The Wayne N. Aspinall Unit, Colorado’s only stake in a federal hydropower system that sells power across the West, is on pace to generate nearly 30% less electricity than its historical average dating to 1978, according to the Bureau of Reclamation. The shortfall is the latest sign of a decades-long decline eroding a system that accounts for about 3% of Colorado’s energy supply.
Aspinall Unit dams
The unit’s three dams on the Gunnison River — including Blue Mesa, Morrow Point and Crystal — make up Colorado’s only piece of the Colorado River Storage Project, a Depression-era network of federal dams selling power to municipalities, cooperatives, tribes and irrigation districts across the West. Blue Mesa Reservoir, the largest body of water entirely within Colorado, is expected to end the year at just 17% of its live storage capacity.
As the river shrinks under the stresses of climate change, so does the unit’s output. And the electricity that the waterway does not help to generate has to come from somewhere else, usually at a higher price.
Nationwide, residential electricity users have already seen an annual price increase of more than 7% in the year ending in March. Judging by Xcel Energy’s recent effort in Colorado to obtain rate increases that might exceed 50% by the end of the decade, additional hits to consumers’ budgets could become the most obvious consequence of the building crisis in the Colorado River Storage Project’s capacity to generate power.
That economic scenario is unfolding as the West braces for a surge in electricity demand from data centers built to power artificial intelligence. On June 18, the Federal Energy Regulatory Commission boosted the effort to hook up those large users when it ordered the nation’s six grid operators to speed transmission connections for AI data centers.
“We are setting the stage for a resilient, reliable, and forward-thinking grid that empowers communities and safeguards consumers by transforming the way large energy users access the grid,” agency chair Laura Swett said.
It’s a lopsided moment, since federal regulators are accelerating new demand onto a grid whose supply side, at least in Colorado, is apparently decaying.
A dangerous threshold
The mechanics of Colorado’s hydroelectricity system are straightforward, even if mostly invisible to consumers. Reclamation operates the dams. The Western Area Power Administration markets the power to “preference customers” at cost-based rates. The Aspinall Unit’s output is pooled with Glen Canyon, Flaming Gorge, and other project dams under the Salt Lake City Integrated Projects Area arrangement, so Colorado utilities hold a share of that pool, not an Aspinall-specific allocation.
Less water also means less pressure, or “hydraulic head,” through the turbines: At full pool, one megawatt-hour at Glen Canyon Dam on the Colorado River takes about 1.9 acre-feet of water and, at today’s lower elevations, roughly 2.9 acre feet, said Jen Pelz of the Flagstaff, Arizona-based Grand Canyon Trust, an environmental organization that advocates for conservation of Colorado Plateau natural resources.
The same mechanism plays out at Blue Mesa. At its current elevation of about 7,446 feet, the reservoir’s generating capacity is approximately 18% below the amount for which it was designed, said Nick Williams, Reclamation’s power manager for the Upper Colorado Basin. Electricity generation stops entirely at 7,393 feet, Blue Mesa’s minimum power pool.

Reclamation moved aggressively this spring to avoid a more dangerous threshold. In April, it projectedinflow at Lake Powell, behind the Glen Canyon Dam, at just 29% of average and warned that without action, the reservoir could fall below its minimum power-pool elevation of 3,490 feet by August. That is the point at which Glen Canyon Dam’s turbines stop generating.

While the agency issued a more optimistic prediction in May, it nevertheless ordered additional emergency releases from Flaming Gorge Reservoir through April 2027 and cut Powell’s release to Lake Mead for the year by roughly 1.5 million acre-feet. That protects Glen Canyon’s generators, partly by drawing down Mead, which has in turn already cut Hoover Dam’s generating capacity by an estimated 5% to 8.5%. The Hoover Dam power production decline is already reflected in the agency’s June forecasts, according to Len Schilling, the Reclamation official overseeing dam operations in the Lower Colorado Basin. None of the agency’s moves solve the shortage. Instead, Reclamation decides, reservoir by reservoir, where the pain lands first.
A test of the cost gap
The clearest documented example of that pain in dollars comes from the Western Area Power Administration’s own numbers. From fiscal 2023 through 2025, the agency paid more per megawatt-hour for replacement power than it charges customers every year and roughly tripled its rate in 2023, narrowing to about 35% above it by 2025, according to a Colorado Newsline analysis of WAPA and federal energy data. WAPA also spent $18.9 million in 2024 and $6.5 million in 2025 on replacement power tied to “Cool Mix,” a protocol that bypasses Glen Canyon’s turbines to protect native fish downstream, according to a Colorado River Research Group report drawing on an Argonne National Laboratory analysis and figures from WAPA.
Platte River Power Authority, which supplies Fort Collins, Loveland, Longmont and Estes Park and holds a direct WAPA allocation, could be the clearest Front Range-based test of that cost gap. A spokesperson for the utility said it could not respond to questions before publication. A recent organization budget cited reduced federal deliveries and rising WAPA rates as adverse financial factors, but current estimated financial consequences for the power authority, and what it will mean for the utility’s customers, remain unclear. WAPA did not respond to requests for comment.
A smaller utility in the state offers a contrasting situation. La Plata Electric Association, the rural cooperative serving Colorado’s southwest corner, relies mostly on the Southwest Power Pool for its electricity supply after joining that regional transmission organization earlier this year. But the association’s chief executive officer, Chris Hansen, said the cooperative still relies on WAPA for a hydropower allocation tied to the Southern Ute Indian Tribe. That WAPA dependence amounts to about 3% of the association’s supply. Hansen said market access and a diversified portfolio buffer the small utility against hydrologic risk.
“Even if that 3% were to double in cost, which is possible, it would have a relatively small impact on our total cost of power purchases,” he said. “So we have low exposure. Other co-ops do not. For us it would be (a) relatively small change.”
Whether joining the Southwest Power Pool can give utilities facing more financial pressure much hedge against rising power costs is not yet clear. Sydney Welter, an energy markets policy advisor at Western Resource Advocates, explained that “with just three months of market operations and without having seen data from Colorado preference customers, I’m not certain what the long-term costs and benefits will be.” While the Brattle Group, an industry watcher, predicted that utilities would save tens of millions of dollars per year by joining power pools, it is not clear whether that is happening.
Rise in demand
Colorado lawmakers considered a bill this year that would have imposed accountability requirements on data centers. Senate Bill 26-102 was killed before the General Assembly adjourned in May, though the issue isn’t likely to fade. Xcel Energy, the state’s largest utility, expects large industrial customers, mostly data centers, to drive roughly two-thirds of its new demand. Nationally, data centers consumed an estimated 4.7% of U.S. electricity, a figure that Lawrence Berkeley National Laboratory projects could reach nearly 12% by 2030. Increasing data center electricity use in Colorado would add pressure to a system that is already experiencing supply reductions caused by the loss of flows at the Aspinall Unit.
That framework also shapes the deeper risk involving a “compact call” to the Lower Basin states demanding delivery of more water from Colorado, New Mexico, Utah and Wyoming. That has never happened in the Colorado River Compact’s history, but it could increase pressure on Western Slope water and power as Front Range cities lease senior water rights across the Continental Divide, according to University of Wyoming law professor Jason Robison.

No one is predicting a call soon. But Pelz argues the standoff between electricity costs and environmental protection is a false choice: The Grand Canyon Protection Act of 1992 already requires dam operations consistent with the river ecosystem’s long-term sustainability, and Congress could have eased the cost pressure through diversified supply or a dedicated fund, but has not done so in the 30 years since that law was enacted. Reclamation is now studying a broader infrastructure fix at Glen Canyon Dam, with initial findings due in 2027.
That may be too late for the pressures already showing up this year at reservoirs like Blue Mesa.

As of July 12, Blue Mesa Reservoir near Gunnison sat only 32% full at 266,000 acre feet of storage water — about 35,000 acre feet less than the historic minimum for that date, down 35%…Severe drought conditions at the reservoir have resulted in critically low storage levels, a limitation on water allocation to the Uncompahgre Valley and its agricultural water users, limited flows for releasing endangered fish species, decreased recreational opportunities on the water that go hand-in-hand with a downturn in the regional recreational economy, and uncertainty over power generation and water usage in the near future. Colorado River District spokeswoman Lindsay DeFrates called it a “crisis”, as the reservoir and the Wayne N. Aspinall Unit — which stores water and generates hydroelectric power through the reservoir as well as the Morrow Point and Crystal Reservoir dams — is one of the upper units that feeds the crucial Lake Powell downstream.
“Everyone’s looking downstream at Lake Powell while we have this happening in our backyard right now,” DeFrates said…

When he was the Division 4 assistant engineer for the Colorado Division of Water Resources (DWR), Jason Ullmann would have never entertained the notion that the Black Canyon of the Gunnison National Park’s portion of the river could ever dry up. Now, as the DWR director and Colorado state engineer, he said it’s unlikely to happen this year or next — but it’s “not an impossibility.”
“The actual inflow from April to July this year was the lowest on record. Barring a change in the climate conditions that produce this monsoon everybody’s waiting for, it doesn’t seem like we’re going to have a significant increase in inflow. We’re going to have one of the lowest inflow seasons — if not the lowest — on record at Blue Mesa,” Ullmann said. “Blue Mesa started the year approximately 20 feet below the normal level it would start the year on. The water levels are very low and will continue to drop.”
Colorado River District Senior Water Resources Engineer Caleb Foy compared 2026 to some of the region’s driest years — 1977, 2002, 2012 and 2018 — and said 2026 “takes the gold medal in terms of poor hydrological conditions”, impacting water storage at Blue Mesa Reservoir which, in turn, has multiple impacts downstream…
Foy noted that the reservoir’s storage could drop below the power pool level, which is the minimum amount of water needed to produce hydropower from the dam. According to the U.S. Bureau of Reclamation’s June 2026 24-month study, this drop could happen as soon as February 2027. According to other forecasts, this drop could happen as soon as the end of this summer if the region sees no monsoon conditions and current operations aren’t modified to preserve storage at the reservoir…A reduction in downstream flow would negatively affect downstream diversions, Colorado River flow, the Black Canyon of the Gunnison, and endangered fish species in both the Gunnison and Colorado rivers. The BOR has worked with Fish and Wildlife to temporarily reduce flow targets while trying to minimize negative impacts to endangered fish species. Ullmann said the minimal target flow for the Endangered Fish Recovery Rights is, in a typical year, no lower than 750 cubic feet per second. This year, the target is at 750 cfs — and last week, the flow was as low as 700 cfs. This has been alarming enough to spark conversations between the state and the BOR.

In the culmination of a process that has been years in the making, Colorado officials Wednesday announced the creation of a state-run water conservation program.
In what officials are calling a “near-term contribution program,” the Upper Basin states (Colorado, New Mexico, Utah and Wyoming) will pay water users to voluntarily cut back in 2027 and 2028, using $100 million in promised funding from the U.S. Bureau of Reclamation. Colorado will now join Utah and Wyoming in setting up a conservation program within their respective states.
The noteworthy, long-expected announcement came at the regular July meeting of the Colorado Water Conservation Board, where board members considered the criteria for the program. A draft list says the program must, among other criteria, avoid negative community impacts; encourage contributions from across the state and water-use sectors; incentivize environmental benefits; encourage tribal participation; and build local drought resiliency. The board is scheduled to finalize the program criteria at its September meeting.
These types of conservation programs have traditionally targeted agricultural water users, often seen as the low-hanging fruit for water savings because they use the majority of Colorado River water. But officials are hoping this program will have participation across all water-use sectors, including municipal and industrial.
“I love that it is called a contribution program because that kind of imagines broader participation and engagement,” said board member Taylor Hawes. “So I think that is good. I think the more flexibility we can have, the better in a program like this.”
But details were scant on exactly how much water Colorado will contribute to the program and how the saved water would be used. And although some experts have begun calling for permanent reductions in water use, it remains — for now — a temporary, short-term program.
“We cannot guarantee a certain amount of water will be conserved in a given year because we don’t know how much water our water users are going to get,” said Amy Ostdiek, interstate section chief at the CWCB. “We have been clear that we just can’t do that.”
In a May letter to federal officials, the Upper Colorado River Commission said it has a goal of saving 100,000 acre-feet by the end of September 2028, which marks the end of water year 2028, but only if sufficient federal funding is available and hydrologic conditions allow. Colorado’s share of the Upper Basin’s allocation is 51.75%, meaning Colorado could be on the hook for 51,750 acre-feet over the next two years.
But Ostdiek said they are not at this time discussing a specific target that Colorado or the Upper Basin would have to contribute in exchange for the $100 million from the Bureau of Reclamation.
“We have felt confident that we can generate up to 100,000 acre-feet by 2028,” Ostdiek said in a Q&A session with the media after her presentation to the CWCB. “But really, what we’re going to be focused on is getting robust participation.”
It’s also unclear exactly how the saved water will be used. Officials said it’s not meant for use by the Lower Basin (California, Arizona and Nevada); it will be for the benefit of the Upper Basin. The water will need to have a home in Upper Basin storage buckets — Lake Powell, Navajo, Blue Mesa or Flaming Gorge reservoirs — but how it will fit into broader reservoir operations is unknown. [ed. emphasis mine]
“I think that is going to be the subject of ongoing discussion, exactly how this water is used and characterized,” Ostdiek said. “I think what we know is that it needs to be credited to or subject to the discretion of the Upper Division states in some way.”

Conservation concept is not new
These types of programs that pay water users to cut back are not new to Colorado, and officials said they are incorporating the lessons learned from previous demand-management studies beginning in 2019, stakeholder input and pilot programs. The state participated in the 2023 and 2024 System Conservation Pilot Program, as well as an earlier version that ran from 2015 to 2018.
But conservation programs remain controversial. The Grand Valley Water Users Association, one of the largest irrigation districts on the mainstem of the Colorado River, did not allow its members to participate in SCPP for fear of negative impacts to other water users in the district.
All of the projects enrolled in SCPP involved agricultural water users on the Western Slope, a potentially risky situation, according to the Colorado River Water Conservation District. The Glenwood Springs-based agency, which represents 15 counties across the Western Slope, had tried to influence the creation of criteria for participation in SCPP to avoid negative impacts to rural agricultural communities.
Ultimately, only the Upper Colorado River Commission determined who got to participate in SCPP. Now, it seems state officials are taking to heart the River District’s recommendations. River District General Counsel Peter Fleming thanked Ostdiek for including some of the criteria that the district had set forth in its principles about how to create a conservation program.
Fleming encouraged the board members to adopt variable pricing to account for the difference in the value of relatively cheap water on the Western Slope versus more-expensive water on the Front Range. Pueblo Water had wanted to participate in SCPP, but the $509 per acre-foot offered in 2024 to Colorado participants was too far below market value.
“You can see the variable economic values of the water assigned there and the need to have variable pricing in order to encourage widespread participation,” Fleming said.
The River District’s position is that the entire burden of a conservation program shouldn’t be borne by the Western Slope, but must also be shouldered by Front Range water providers, who collectively deplete the Colorado River basin by about 500,000 acre-feet a year.
He added that a program should also have a strong element of local control.
“The River District obviously would like to stay involved in this process,” he said.
The creation of a conservation program for Colorado comes at a critical time for the basin, which remains locked in the grip of a historic drought, with combined storage in Lake Powell and Lake Mead at an all-time low since the reservoirs began filling. Although the Upper Basin has argued that it has never used its entire allocation granted by the 1922 Colorado River Compact (and therefore shouldn’t have to cut back), in the face of dwindling flows and calls for conservation from its downstream neighbors, the four states can no longer avoid reducing their water demand.
The Colorado River basin is also in the midst of a management crisis, with the seven states that share the river still unable to find agreement on a new framework after more than two years of failed negotiations. The current guidelines for how shortages are shared and how reservoirs are operated expire this year, and the feds are poised to step in with their own management plan, expected later this month.
The Upper Basin would need separate parallel agreements with Reclamation alongside the federal management plan to account for and get credit for water saved through the contribution program.
In her presentation, Ostdiek gave a preview of Reclamation’s expected plan, which could allow for a pool in Lake Powell to store up to 3 million acre-feet conserved by Upper Basin states. But board chair Barbara Vasquez worried about overestimating the amount of water that could be contributed given the recent historically dry conditions. Farmers and ranchers across Colorado are now experiencing the fallout from the worst snowpack on record in the form of shortages and fallowed fields.
“So prior programs, we spent a lot of money for very little water conserved. I worry that next year may be even worse than this year, and it’s not willingness, but ability,” Vasquez said. Given the water that’s available, she said, “that might disappoint expectations on the part of the negotiators at the table for the Colorado River.”

On July 13th, the Colorado River District, in partnership with the Colorado Water Trust and the Yampa River Fund, began releasing water from Elkhead Reservoir to mitigate the impacts of extreme drought and critically low streamflows in the Yampa River Valley. Beginning with a release of 10 cubic feet per second, the releases are part of the Yampa River Reservoir Release Program, a 2,000-acre-foot pool first established in 2021 with funding from the Colorado River District’s Community Funding Partnership. The program is designed to reduce drought-related pressure on agricultural producers while supporting river health and aquatic habitat.
“While we’re experiencing exceptionally difficult drought conditions, the story of 2026 is neighbors and water users working together. No single reservoir, organization or water user can solve this alone,” said Hunter Causey, Chief Engineer for the Colorado River District. “By coordinating releases, operations and water use across the basin, we can stretch a limited supply further and provide meaningful benefits for agricultural producers, local communities and the river.”
Below-average snowfall and persistent summer drought have reduced streamflows and increased water temperatures throughout the Yampa River Basin. Releases through the Yampa River Reservoir Release Program are intended to support agricultural water users, help delay or prevent a call on the river during periods of critically low flow, and benefit designated critical habitat for four endangered fish species. Releases are expected to increase in the coming weeks and continue through July.
“The Colorado Water Trust is an environmental nonprofit, and our work is keeping water in rivers,” said Blake Mamich, Programs Director for the Colorado Water Trust. “In a drought this deep, that same mission means showing up for agriculture. Coordinating closely with the River District and the Division of Water Resources, we can time these releases so a single pool of water helps irrigators extend a tough season and keeps water in Yampa for habitat and fish.”
“This is a difficult year for producers throughout the Yampa Valley, and we wanted to be part of a practical solution that helps the broader community,” said Yampa Basin rancher Matt Boeddeker of Lily Park Land & Cattle. “Water users across Colorado are making hard choices and working together to stretch limited supplies, and like them, we hope to help our neighbors complete critical irrigation and reduce the immediate impacts of drought.”
The Yampa River is primarily supplied by snowmelt from the Flat Tops and Gore Range and flows through agricultural areas of northwest Colorado before joining the Green River in Dinosaur National Monument. During dry years, coordinated releases from Stagecoach and Elkhead reservoirs supplement streamflows for agricultural water users, river habitat and endangered fish. The Colorado River District and its partners will continue to monitor streamflow, water temperature, irrigation demand, and habitat needs, and will adjust releases as conditions warrant.
The Colorado Division 3 water trial that virtually every farmer and rancher who operates in the Upper Rio Grande Basin is paying attention to is on track to wrap up this week, with former State Engineer Kevin Rein scheduled to testify before final arguments are made, Judge Michael Gonzales signaled Monday.
San Luis Valley Groundwater
The trial in Alamosa water court deals with the Fourth Amended Plan of Water Management for Subdistrict 1 of the Rio Grande Water Conservation District, which outlines a new approach to the aquifer recovery by limiting the subdistrict’s groundwater withdrawals to the amount of surface water that naturally comes into the lands annually. It is the subdistrict with the largest cash crop receipts in the Valley’s growing fields, the subdistrict with the largest volume of groundwater pumping, and the subdistrict under orders from the state to recover the basin’s shallow unconfined aquifer.
The new plan, approved by Rein before he retired as state engineer in 2023, has been dissected by farming operations protesting the plan in water court by arguing groundwater irrigators will be driven out of business because of the plan’s limits on groundwater pumping and a hefty $500 per-acre-foot pumping fee.
“It will be a hard nut to crack,” Dee Greeman, who works the L Cross Ranch, testified Monday.
L Cross is among the operations protesting the plan. Given the multi-decade drought conditions, the overpumping fee and the fact L Cross would no longer be allowed under the new plan to offset its pumping with its own surface water as credits to its groundwater withdrawals, the value of the ranch would be affected long term, Greeman told the court.
“It’s a gamestopper,” he said, if wells can’t pump because it is from its groundwater pumping that L Cross finds profit in producing hay.
Greeman’s testimony on Monday wrapped up presentations by the different protestors to the plan. The state Division of Water Resources, which is defending the plan, will bring back witnesses to rebut different testimony and key to it all will be Rein.
It was the testimony of former state Division of Water Resources engineer Ken Knox at the conclusion of week 3 of the trial that prompted Gonzales to tell the state that it is only common sense for Rein to testify. Knox trashed Rein’s review, saying it didn’t take all the proper steps and didn’t include all the critical information for a state engineer to conduct a review of a water management plan.
Following a motion Monday by Preston Hartman, the state assistant attorney general defending the Fourth Amended Plan in water court, to dismiss the protestors case, Gonzales ruled that the protestors have provided sufficient evidence to keep going and scheduled closing arguments for the end of week after Rein testifies on Wednesday.
Once the final arguments are made, Gonzales will set a timeline for his review and decision.
“This is not something we want to push out too far,” the judge said at the conclusion of Monday’s session.

Even in the driest of years — like this one — powerful Western Slope water rights on the mainstem of the Colorado River draw water downstream, making boating on the state’s major water artery possible.
“For mainstem floating, we should still have pretty darn good flows for the rest of the season for as long as people want to be boating,” said Sam Calahan, a water resources specialist for the Colorado River District. The taxpayer-funded agency is based in Glenwood Springs and works to protect Western Slope water…
On Wednesday, Browns Canyon — a popular section of the Arkansas River near Buena Vista — was flowing at the lowest level in 55 years of data and at 16% of its median flow for that date. Clear Creek near Idaho Springs was flowing at 61 cubic feet per second on Wednesday, also a record low for the date in 72 years of data. The median flow for the date is 347 cfs, or more than five times as much water…But flows on much of the Colorado River were high enough for rafts and kayaks this week. Flows on a popular section near Kremmling were near normal, as were water levels farther downstream in Glenwood Canyon. Two major factors keep water flowing down the Colorado River during drought: large senior water rights owned by farmers in Mesa County’s Grand Valley and the water rights connected to the Shoshone Power Plant, a hydroelectric facility in Glenwood Canyon owned by Xcel Energy. Irrigators and power plant operators can call water to their facilities from upstream reservoirs, like Green Mountain Reservoir, which is on the Blue River — a tributary of the Colorado River — north of Silverthorne. This year, the irrigators began calling down water on July 1, boosting flows in the Colorado River.
Colorado Division 3 Water Court Judge Michael Gonzales said from the bench Friday that he wants to hear from former State Engineer Kevin Rein and without his testimony it will be “very hard for this court” and its decision on whether to allow the Fourth Amended Plan of Water Management in Subdistrict 1 to go into effect.
And that’s how Week 3 of the most important water trial in the past 25 years affecting the Upper Rio Grande Basin ended in Alamosa water court – the judge telling the state Division of Water Resources as it defends the plan that he would like to hear from the state engineer who approved the plan.
“Without hearing from Mr. Rein, it’s a concern,” Gonzales said.
Earlier during Friday’s afternoon session, he cautioned attorneys on their tone and their questioning of witnesses in a week when emotions inside the courtroom ran high.
“Let’s everybody cool their jets,” the judge said before he added an extra 10 minutes to the afternoon courtroom break.
The week opened with State Engineer Jason Ullman telling Gonzales that without the Fourth Amended Plan in action, Subdistrict 1 faces widespread curtailment since it will not meet the “sustainable” level of the unconfined aquifer by 2031 when the current plan of water management expires.
In 2018 Rein first alerted the Rio Grande Water Conservation District that broad curtailment could be on the table given the lack of progress in restoring the unconfined aquifer. It was then the subdistrict began working on a fourth amendment to its water management plan, which was ultimately adopted by the Subdistrict 1 board and then the Rio Grande Water Conservation District before Rein gave his sign off.
Ullman, who succeeded Rein as state engineer, told the court as he wrapped up his testimony that in his view the Fourth Amended Plan of Water Management, which features a one-for-one pumping mechanism, is the “most reasonable I can think of that would be likely to cause the aquifer to increase in level.”
The one-for-one features means the subdistrict would offset its groundwater withdrawals by returning an acre-foot of water for every acre-foot pumped during the irrigation season. The new plan also contains an overpumping fee of $500 per acre-foot which groundwater irrigators would pay if they cannot offset their groundwater withdrawals with their own surface water or surface water credits.
“Like I said, I understand that that decision has consequences, but there’s pretty significant consequences to doing something. And at some point as the policy decision makers, we have to make a decision to do something to meet these goals the General Assembly has set out. And I feel like that’s what we’ve done here. The consequences of doing nothing are much more drastic and draconian than the consequences of this plan,” Ullman told the court.
It was Rein’s review and sign off on the Fourth Amended Plan that has come under scrutiny by opponents to the plan. Rein retired at the end of 2023 after approving the plan and conducted this exit interview with Alamosa Citizen. During the conversation for an episode of The Valley Pod, he was reluctant to dive into the details of the plan because it was headed to water court and Judge Gonzales for a legal review.
“Without saying too much about that and the groundwater management plan for the subdistrict, from my perspective as a state engineer, there’s one critical aspect of that for both cases and that is the sustainability of the unconfined aquifer. As we know, that’s a difficult component of groundwater management in the Valley because we have a statutorily required sustainability objective. And that has found its way into the rules and into the groundwater management plan for the subdistrict,” he said at the time.
He added that under the existing plan of water management for Subdistrict 1, “it’s going to be very difficult to meet that sustainability objective … And I know that the subdistrict has worked hard toward an alternative in this current plan that I approved and is before the court, and the way that plays out is going to be so important to the irrigators in the Valley.”
Ken Knox, a former employee of state Division of Water Resources who at one point served as acting state engineer for approximately 18 months, criticized Rein during his testimony Friday for not conducting a thorough review and that the plan in sections was “devoid of necessary information” to approve the plan by the state engineer.
Rein’s review was a “dramatic step backwards for professionalism of agency standards,” Knox told the court. He was the final expert witness for the Northeast Water Users Association and Sustainable Water Augmentation Group, who are asking Gonzales to throw the plan out on legal grounds.
Rein’s review was a “dramatic step backwards for professionalism of agency standards,” Knox told the court. He was the final expert witness for the Northeast Water Users Association and Sustainable Water Augmentation Group, who are asking Gonzales to throw the plan out on legal grounds.
The farmers opposing the plan are trying to thread a few legal arguments to persuade Judge Gonzales to reject the plan. Their contention is the Northeast Water Users Association and Sustainable Water Augmentation Group are being asked to bear a disproportionate share of the burden in the aquifer recovery efforts because they are groundwater irrigators. They contend Rein didn’t conduct a full legal review of the sustainability and proportionality rules contained in state statutes governing recovery of the unconfined aquifer and the $500 fee makes the plan beyond the economic means of all the irrigators who hold water rights in the subdistrict.
“My land would have no value,” groundwater farmer Asier Artaechevarria testified, acknowledging that his operations rely 100 percent on groundwater withdrawals.
Ernie Myers, another farmer opposing the plan and who served on the Subdistrict 1 board for a several years, said it was after 2002, when the Upper Rio Grande Basin first experienced historic low flows from a lack of snow runoff, that he first began to feel targeted as a groundwater irrigator and had the feeling that surface water farmers were trying to put him out of business.
“I was pumping their water. I had no right to pump their water. I had a few farmers telling me, ‘I’m third, fourth generation. You’re a newcomer. You came in ’73 with your father. You have no right to do what you’re doing,’” Myers testified.
“And were there actually people saying that they intended to put you out of business?” a SWAG attorney asked.
“Yes, yes,” testified Myers.
Myers was the first to testify on behalf of SWAG and the Northeast Water Users Association. Knox was their final witness, and it was after his testimony that Gonzales made his interest in Rein testifying known.
“Common sense means a great deal to me,” the judge said.
Common sense tells the judge he should hear from the person who approved the plan he’s being asked to give legal approval to.
The trial resumes Monday with the L Cross Ranch, another legal opponent to the plan, making its arguments before Gonzales.

This week, rain returned to Pagosa Country, bringing some relief from the dry heat that dominated June and early July and heralding the start of the summer monsoon season. Weather modeling by the National Integrated Drought Information Center (NIDIS) suggests that the summer monsoon season is likely to bring average or above average precipitation to the region — a bounty compared to the approximately 25 to 50 percent of average precipitation Archuleta County received in last month. The National Weather Service Climate Prediction Center forecasts that drought conditions in the area will improve by Sept. 30, although it suggests that current severe and extreme drought levels calculated by the U.S. Drought Monitor will persist through July.
The Pagosa Area Water & Sanitation District is currently in drought stage two, which includes a number of restrictions on outdoor irrigation, as well as additional fees for high water use. In stage two, irrigation is allowed only between 9 p.m. and 9 a.m. every other weekday, with even-numbered addresses able to irrigate on even-numbered days and odd-numbered addresses on odd-numbered days. Weekend irrigation is prohibited. However, drip irrigation and hand watering edible or ornamental gardens is allowed at all times. Residential water use above 4,000 gallons per month is subject to a two times rate multiplier. PAWSD District Manager Andrew Connor explained that, while the rains associated with the monsoons might eventually impact the district’s drought restrictions, changes would require a large amount of rain and would not be immediate. In the summer, the drought stage is primarily driven by the water level in Hatcher Reservoir, flows in the San Juan River and the date…
PAWSD District Engineer Justin Ramsey explained that the district’s drought management plan focuses on irrigation since it composes a large portion of the district’s water use in the summer and because losing green lawn grass or other plants has a smaller impact on people’s lives than restrictions on showering, dish washing or other indoor water uses…The drought stages in the district’s drought management plan align with this goal, imposing progressively tightening restrictions on when irrigation can occur while placing no restrictions on indoor water use except increasing fees for high water consumption. However, for all but the most severe drought stage, these restrictions only cover irrigation done with sprinklers and other automated devices, with the use of drip irrigation devices and hand watering allowed at all times…Manual and drip irrigation encourage people to be more conscious about how they use water by involving them more deeply in the process and requiring more hands-on time, he added. Another way to increase the water available for gardens and landscaping without paying more fees is to reduce water waste in your home, Connor and Ramsey highlighted.

July 16, 2026
Sara Porterfield, Colorado River program director with the conservation nonprofit Trout Unlimited, stood on a narrow, rocky river beach, about as close to Glen Canyon Dam as a boat can go.
“This is not a zero sum game,” she said. “Investing in watershed health is not an either-or. We need the system to be healthy from an ecological perspective in order for the rest of it to function.”
The river, Porterfield said, cannot deliver big volumes of clean water if it does not, at least partially, function like a normal, healthy river. For example, if the river’s upper reaches are dried out, they’ll be susceptible to wildfires and wetland degradation, which make it harder for them to hold on to water and release it slowly into the streams where humans have been able to reliably divert and collect it for generations.
“It’s not just plumbing, but it’s also not just water in a river,” Porterfield said as the dam’s hydroelectric generators emitted a whining hum in the background. “We’re not separate from the natural world, we’re part of it. When we recognize that, and we take help to take care of it, we get a lot further than when we’re just thinking about a plumbing system.”

Porterfield, who has a Ph.D. in Colorado River history, said calling the river a “plumbing system” is a useful way to think about one of its jobs, but not the whole picture. Environmental advocates say the river can be protected while still flowing through the dams and canals that keep the West wet for humans. Those protections can even be part of the wonky and rigid legal policies that dictate where water goes. John Berggren, a water policy manager at the conservation nonprofit Western Resource Advocates, had some recommendations for the next set of river-sharing rules. An important one, he said, is to get the river out of “crisis mode.”
[…]
“You can be much more proactive and thoughtful and careful and intentional about how you manage the river and include river health,” he said.
Another way to help protect the river’s ecosystems, creatures and flows, Berggren said, is by carefully timing the release of water from reservoirs. For example, policymakers can write flexible rules about where and when water is stored, so water that is flowing downstream to cities and farms can also help make life better for native fish. The water can be used to help the environment without being taken away from humans downstream.
“They’re going to move the water anyway,” he said. “Let’s do it in a way that actually benefits ecological conditions.”

From email from Reclamation (Andrew Limbach):
July 14, 2026
Aspinall Unit Operations Update – Release scheduled change to 1,390 cfs on Wednesday, July 15th.
On Wednesday, July 15th, the adjusted scheduled releases from Crystal Dam will decrease to 1,390 cfs from 1,465 cfs.
Gunnison River flows in the Black Canyon/Gunnison Gorge will decrease to 360 cfs.
On Thursday, July 16th, the adjusted scheduled releases from Crystal Dam will decrease to 1,315 cfs from 1,390 cfs.
Gunnison River flows in the Black Canyon/Gunnison Gorge will decrease to 290 cfs.
Reclamation will continue to monitor flows in the Gunnison River, and on Friday, July 17th, the scheduled releases from Crystal Dam may decrease to 1,265 cfs from 1,315 cfs.
Gunnison River flows in the Black Canyon/Gunnison Gorge would decrease to 250 cfs. An additional notification will be sent out confirming any change after Wednesday.
In response to the extreme drought conditions, the BOR has collaborated with US Fish and Wildlife and the National Park Service to reduce the target flows to 500 cfs at Whitewater and 200 cfs through the Black Canyon of the Gunnison until further notice. These releases are made for the authorized purposes of the Aspinall Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the Gunnison while preserving critical storage in Blue Mesa Reservoir.
Contact Andrew Limbach (alimbach@usbr.gov or 970-248-0644) for more information regarding Aspinall operations or the Operation Group meeting.

The Colorado River watershed’s spring runoff — if you can call the measly increase in streamflows “runoff” — peaked in mid-May and was pretty much over by mid-June.
The variations in streamflow showed up as a little bump in Lake Powell’s total inflows, which were augmented by extra releases from Flaming Gorge reservoir on the Wyoming-Utah border, many miles upstream. That buoyed Lake Powell’s surface level to a high point of 3,528 feet in early June, before it began its long decline that’s likely to continue until next year’s runoff.
The reservoir’s surface level is currently at about 3,525 feet, the lowest it has been since 2023 and the lowest it has been on this date since it was filled. It’s also the level that would trigger a reduction in releases from Glen Canyon Dam to 7.48 million acre-feet per year. This year that’s not going to happen, because releases are already on track to be closer to 6 MAF.
The data show why, even with reduced releases, the surface level is falling at about two inches per day as of the beginning of July.
3,527.97; 3,524.99 feet above sea level: Surface elevation of Lake Powell on June 1 and July 6, respectively.
2.1 million acre-feet: Median total inflows into Lake Powell (1991-2020).
399,304 acre-feet: Total inflows into Lake Powell during the month of June 2026, or about 19% of “normal.” The “unregulated inflow,” which is what the inflow would be without augmentation from upstream reservoirs, was just 305,000 af.
507,747 acre-feet: Total releases from Glen Canyon Dam in June 2026. At this level, all releases go through the hydroelectric turbines and generate power.
20,475 acre-feet: Estimated amount of water lost to evaporation from Lake Powell in June 2026.
8,951 acre-feet: Inflow into Lake Powell on July 7, 2026.
15,546 acre-feet: Release from Glen Canyon Dam on July 7, 2026.
788 acre-feet: Estimated evaporation from Lake Powell on July 7, 2026.
(7,383 acre-feet): Lake Powell’s daily water deficit on July 7, 2026.
In other words, as of early July the reservoir was losing nearly 7,400 acre-feet of water each day, or about 220,000 acre-feet per month. If this rate of decline continues or speeds up, then we can expect the reservoir to reach de facto deadpool — or 3,500 feet — before the end of the year.
If the level drops below 3,500 feet, dam operators will no longer be able to release water through the penstocks and hydroelectric turbines, meaning they must rely entirely on the river outlets lower on the dam for all releases. This would not only zero out the dam’s hydropower output, but could also damage the outlet tubes, since they aren’t engineered for long-term, sustained use.
One possible scenario: Dam operators switch to the river outlets for releases, the reservoir’s surface level is drawn down to, say, 3,475 feet, then the river outlet tubes begin deteriorating due to cavitation, forcing them to be shut down. This would then make it impossible to release any water from the dam until the outlets were repaired or the lake level rose back up to 3,500 feet, meaning the Colorado River in the Grand Canyon would effectively dry up completely.
That’s why the Bureau of Rec is so intent on “defending” that 3,500-foot level, presumably even if it means going to a run-of-the-river operation, in which water is released from the dam at the approximate rate that it is flowing into the reservoir, minus evaporation. On July 7, this would have amounted to about 2,800 cubic feet per second, or about one-third of current releases, diminishing hydropower output, and affecting downstream recreation and aquatic life.
If — or more likely, when — this occurs, it will render Lake Powell useless as a water savings account, and reduce it to a marginal power generator, silt collector, and evaporation pool. Boating will still be possible, but most existing boat ramps will no longer be usable. This will lend strength to calls to drain the reservoir, either by decommissioning the dam altogether, or by building bypass tunnels that can be shut down if climatic conditions change and aridification is reversed.
In the video above Katrina Grants from Reclamation explained how her agency is planning operations of Glen Canyon Dam for the next few years and emphasized that they can operate safely with just the outlet tubes, with increased maintenance activity. The planning shows the river hydrology is the primary driver of releases rather than limitations from the tube design. “We can release the water if it is there,” she said.
⛏️ Mining Monitor ⛏️
The U.S. Forest Service granted final approval to South32’s proposal to re-open and expand the Hermosa Mine in southern Arizona to extract battery materials such as manganese and zinc, along with silver and lead.
The mine is on patented claims (private land), but would be expanded onto unpatented claims in the Coronado National Forest in southern Arizona’s Patagonia Mountains, an area long inhabited by the Sobaipuri O’odham and Hohokam people. The mountains occupy the nexus of several different biological provinces and are home to hundreds of species of birds, bees, bats, and butterflies, as well as the unique Madrean Pine-Oak Woodlands.
The approved plan of operations includes:
Disturbance of about 400 acres of Forest Service land, including 225 acres for tailings and waste storage.
Mining will be done by the long-hole open stope method at a projected rate of about 4.7 million tons of ore per year.
The Australian company has approval to discharge up to 4,500 gallons per minute of treated water into Harshaw Creek, Mowry Wash South, and Goldbaum Canyon.
During operations the plan anticipates 169 heavy truck round trips per day and 76 light vehicle or bus round trips per day on the main access road, which will be constructed for the project.
The Biden administration expedited the environmental review for the proposed plan back in 2023 because the materials extracted are considered “critical.” Manganese is used in large capacity batteries; zinc is used to galvanize steel.
Area residents and advocates worry this sort of industrialization will harm the delicate and unique ecosystem and the diverse array of wildlife that depends on it. As is often the case with underground hardrock mining, a primary concern is for its effects on water quality and quantity. Groundwater pumping is expected to deplete area aquifers, which could affect springs and wells. Acid mine drainage is expected to occur in the sulfide ore body, which, if not treated properly, could contaminate groundwater or streams in the arid region.
The West these days is teeming with so many fly-by-night mining companies and speculators staking claims on public lands and launching exploratory drilling projects that it’s hard to tell which ones to take seriously. Most of these bids will likely fizzle out as soon as commodity prices fall.
Faraday Copper’s Copper Creek Project, however, seems to be worth paying attention to, if only because they have some serious financial backing.
The Canada company just finalized its agreement to acquirethe shuttered San Manuel copper mine in southern Arizona from BHP Group Limited. BHP, a global corporation and a co-proponent of the proposed Resolute copper mine at Oak Flat, will take a 30% equity interest in Faraday when the deal is completed later this year.
The San Manuel mine, just outside Mammoth, Arizona, was once the nation’s largest underground copper mine and a significant producer up to its closure in 1999. “The definitive agreement provides a pathway for the development by Faraday of a new copper hub in Arizona,” said a BHP press release, “combining existing infrastructure and mineral inventory at San Manuel with Faraday’s adjacent Copper Creek project.”
Faraday’s Copper Creek Project properties near Mammoth, Arizona.
The proposed Copper Creek mine covers about 78 square kilometers in the Galiuro Mountains about nine miles east of Mammoth. Its open pit would likely be in the middle of Copper Creek, a tributary to the Lower San Pedro River. Last June, the Bureau of Land Management approved Faraday’s plan to construct 67 drill pads, along with associated roads and infrastructure, and the company recently completed the first round of water-intensive drilling. The firm reports that the drilling identified oxide mineralization that “supports potential open-pit resource expansion.”

For now, at least, Faraday is not really a mining company. It holds mining claims at the Copper Creek project in Arizona and another “pre-feasibility” project in Nevada, but it has yet to do any actual mining. It’s an exploratory company that last year posted a net loss of nearly $28 million.
Still, it’s getting some help from some very deep-pocketed interests. First off there’s BHP, assuming the San Manuel deal goes through. And then there’s the backing of the Lundin Group, which owns metal and diamond mining, petroleum, and renewable energy companies around the world. Lundin, which was founded in Sweden, is also known for human rights violations. Two executives of Lundin Oil (now Orrön Energy and owned by another company) allegedly aided and abetted war crimes in what is now South Sudan in the late 1990s and early 2000s. Their trial in Stockholm ended in late May and a verdict is expected later this year.
The development has sparked pushback from residents, advocates, and tribal nations, who worry about the drilling’s potential impacts to water quantity and quality in the Lower San Pedro River, which flows nearby, not to mention the prospect of a giant open pit mine in the biodiverse mountain range. The proposed mine site is also near the Aravaipa Wilderness Area, a stunning canyon and desert riparian zone.

The proposed mine site is also near the Aravaipa Wilderness Area, a stunning canyon and desert riparian zone.
There’s also an ironic twist to this situation. In order for Resolution Copper — a BHP/Rio Tinto partnership — to move forward on its Oak Flat mine near Superior, Arizona, about 40 miles northwest of the Copper Creek project, the company had to do a land exchange. It would take ownership of Oak Flat — USFS land that had been withdrawn from mineral entry in 1955 — in exchange for various private parcels in the region with environmental or recreational significance. One of those gained by the federal government is a 3,050-acre parcel along the Lower San Pedro just east of Mammoth; putting it in federal hands should have protected the stretch from development. But it also covers the Copper Creek-Lower San Pedro confluence, and lies between Faraday’s Copper Creek Project and BHP’s San Manuel Mine. In other words, it would potentially be affected, directly or indirectly, by Faraday’s project.
Actual mining isn’t going to happen anytime soon; Faraday has paused its drilling program for the summer and doesn’t plan to resume until the fall. But the deal with BHP and the funding from Lundin are reason enough to keep an eye on this one.
🥵 Aridification Watch 🐫
Speaking of the San Pedro River, one of southern Arizona’s iconic streams and biodiversity zones, it reportedly has gone dry for only the second time in the last century at its Charleston gage. To be clear, the San Pedro is not a huge river, and it has been reduced to a mere trickle at times. But for it to completely vanish at this particular gage — the last time it happened was in 2005 — is a sign that aridification and groundwater overpumping are coming together to destroy one of the last un-dammed desert rivers in the Southwest.

Of course, the San Pedro is not alone. Nearly every stream in the Interior West is running at below normal flows currently. The Dolores River below McPhee Dam is so depleted that a helicopter searching the stream for water to dump on the Ferris Fire came up empty. The San Miguel River at Uravan, Colorado, is flowing at just 6 cubic feet per second, which is about 2% of the median flow for this date. And the Animas River below Aztec, New Mexico, is running at a measly 16 cfs, which is far too low for Farmington’s surf wave.
And of course, we can’t forget about the beleaguered Rio Grande. Laura Paskus reports that 87 miles of the Middle Rio Grande have gone dry. She has a heartbreaking account of walking a stretch of the dry zone near Albuquerque at her Substack newsletter.
Unfortunately, conditions are likely only to get worse this weekend, as a heat wave moves in and scorches the West, especially parts of the central and northern Rocky Mountains. Temperatures are forecasted to reach the triple digits in places like Hotchkiss and Grand Junction, Colorado. And check out this weekend forecast (7/11-7/14) for Thermopolis, Wyoming.

🤯 Oh, the Humans! 😱
The San Miguel County Sheriff’s Office is a bit irritated, if their social media posts are any indication. This week they received a Garmin SOS signal from someone who had apparently fallen 150 to 200 feet in the Columbine Basin above Telluride, broken his leg, and needed search and rescue’s help.
Following an extensive rescue team deployment, which included a CARE Flight helicopter flying into the scene at 13,000 feet in elevation, the SAR team found the victim walking around. He told them he was BASE jumping on his own, his chute didn’t open, and he was injured in the fall. But the broken leg thing? Nope: He not only refused a helicopter flight, but any assistance at all. Adding to the annoyance: The purported victim had previously triggered a massive SAR operation while BASE jumping in the Swiss Alps that included a $175,000 air evacuation.
“Our SAR team consists of skilled professionals who risk their own lives to help others in need,” said Sheriff Dan Covault in a statement. “This individual chose to participate in an extremely dangerous activity alone, and particularly given his prior rescue history, his actions demonstrated a disregard for the risks involved and the resources required to rescue him. His decisions unnecessarily diverted emergency resources, including a Care Flight helicopter, that may have been needed for other emergencies. The fact that he was able to hike back down shows a profound lack of respect for the tremendous effort and resources devoted to this rescue.”

Some kind of “biblical flood” would have to occur over the next few years for the unconfined aquifer of the Upper Rio Grande Basin to recover, given the current downward measurements and the anticipated negative trajectory of the shallow aquifer’s storage area. That according to State Engineer Jason Ullman, whose testimony Friday wrapped up week 2 of the Subdistrict 1 Fourth Amended Plan of Water Management trial underway in Alamosa state Division 3 Water Court.
Ullman followed by telling the water court that without such a historical climate event, the current Subdistrict 1 Plan of Water Management is unlikely to meet its goal of reaching a sustainable aquifer by 2031, or five years from now and 20 years since the plan was first approved.
His option over the next five years without a new plan of water management, he told Division 3 Water Court Judge Michael Gonzales, would be to not approve annual replacement plans, which is the mechanism groundwater well pumpers use for irrigation.
If annual replacement plans don’t get approved, wells cannot pump.
San Luis Valley Groundwater
“I think I would say that it’s nearly impossible outside of some kind of biblical flood,” he testified of the current state of the unconfined storage area. “And even if that was to happen, there’s a limit to how much water can infiltrate into the aquifer on an annual basis or a monthly basis. So I don’t know that you can infiltrate enough water into the aquifer to reach that level by the 2031 deadline.”
According to monthly readings by Davis Engineering, the unconfined storage study area is measuring as low as it ever has since measurements by the consultant firm began in 1976, the court heard.
“In your opinion, will the current plan’s method of dry-up be able to achieve aquifer sustainability?” Rio Grande Water Conservation District lawyer Pete Ampe followed up with Ullman.
“No,” the state engineer told the water court. “I think it’s clear that based upon previous testimony that the goal in the previous plan was to reach 40,000 acres of dry-up that would’ve resulted or estimated to result in 80,000 acre-feet of reduction in use from the aquifer. And I think previous graphs showed that that has occurred, and yet we still see this precipitous decline.
“I mean, I think some folks have talked about how it’s maybe leveled out some, but if you look here at the graph, if I was to plot a longer term or a longer than five-year average, I think you could agree that the trend is downward. It’s not upward, which is problematic when we have very limited time, five years to reach the sustainable water supply level defined in the current plan.”
The sustainable measurement definition is a five-year running average of water storage at negative-400,000 to negative-200,000 below surface and toward the 1976 readings.The current measurement, according to court exhibits, is 1.2 million acre-feet below and declining.
The state engineer’s office approved the fourth amended plan in June 20203, and it is the state engineer who would order widespread groundwater well curtailment. Gonzales must approve the new plan for it to move forward and Ullman to take that option off the table.
During testimony throughout week 2 of the subdistrict plan of water management trial, state Division 3 engineer Craig Cotten and state engineer Ullman testified to the limited amount of time left, without court approval of the updated plan, before wells are shut off.
“We have other impacts because of the lower aquifer supply that are occurring to other water users, to well owners,” Cotten told the water court. “As I’ve discussed, the amount of electricity costs that it takes to pump water out from a lower aquifer, the lowered efficiency of getting flood irrigation across a field, the impact to the environment from not having a water table at the near surface and potentially some ponds around. So lots of impacts. And I do think that we do need to recover the aquifer in a reasonable time period.”
The water trial is moving along speedier than anticipated during pre-trial conferences when Gonzales set the case to be over five weeks. William Schreüder, who created and maintains the Rio Grande Decision Support System Groundwater Model which is a key exhibit in the case, faced limited cross examination to his testimony, and Clinton Phillips, who maintains the unconfined aquifer storage area study for Davis Engineering and whose monthly storage graph provides key data for the state Division of Water Resources decisions, faced no cross examination.
One attorney, Mirko Kruse who is arguing his family’s specific concern around ditch decrees but overall supports to new plan, told the judge that in trying to be efficient with the court’s time he was prepared to make the very specific legal points to his client’s objections next week, if the judge wanted to hear those early.
The judge declined and said he preferred to hear all the expert witness testimony first.
There is little argument to the problem that the unconfined aquifer storage is declining due to groundwater withdrawals and the warming climate of the era, which is hugely problematic for any natural recovery through high elevation snow melt.
After two weeks, the arguments before Judge Gonzales center around surface and groundwater water rights, recharge decrees, and whether the fourth amended plan was crafted legally and openly and creates an economically fair playing field for all the irrigators in the subdistrict.
“Dr. Schreüder, what in your opinion does this all just come down to?” came the question from RGWCD attorney Pete Ampe toward the end of Friday.
“Well, your Honor, the basic premise of the fourth plan is that they will do one-for-one (pumping) which means we’re going to put more water into the aquifer than we’re going to take out and it’s common sense that under those conditions the aquifer should recover.”
The trial moves into week 3 on Monday, July 13, with State Engineer Ullmann still on the witness stand.

Click the link to read the article on the Pagosa Springs Sun website (Josh Pike). Here’s an excerpt:
July 8, 2026
On July 6, Pagosa Area Water and Sanitation District (PAWSD) District Engineer Justin Ramsey issued a clarification to the district’s stage two drought restrictions, indicating that outdoor irrigation is allowed between 9 p.m. and 9 a.m. In his clarification, he explains that the district’s drought management plan had sections that indicated that irrigation was restricted to between 6 p.m. and 9 a.m. and sections that indicated the limitation was between 9 p.m. and 9 a.m. He adds that the district has now settled on the latter interpretation, which is different from some previous sources of information about the drought restrictions. The other restrictions for drought stage two remain the same. Irrigation is allowed every other day at the designated times on weekdays, with odd-numbered addresses watering on odd-numbered days and even-numbered addresses watering on even-numbered days. Weekend watering is prohibited. Edible and ornamental gardens can still be hand watered or drip irrigated. Residential water use above 4,000 gallons a month is subject to a two times rate multiplier under drought stage two. Restaurants are required to serve water only on request, and hotels are encouraged to only replace towels and bed linens for new guests and at the request of current guests. The goal of drought stage two is to reduce water usage by 20 to 30 percent, according to the PAWSD drought management plan…
The U.S. Geological Survey’s (USGS’s) water flow monitoring data is the primary window into local river flows, which factor into PAWSD’s drought stage calculations. The primary monitoring station for the San Juan River in Pagosa Springs is located underneath the bridge where U.S. 160 crosses the river near 1st Street. The reported flows have undergone significant recalibrations this month, with flows in the San Juan River appearing at times in later June to drop below the historic low flows in 2002 before being revised upward. These revisions are partially driven by last year’s flooding events, explained Kyle Raimer, who works as a hydrologic technician for the USGS Colorado Water Science Center’s Western Colorado Office in Durango. Raimer stated that the monitoring system sends out a radar pulse every 15 minutes, which contacts the water below the monitor and returns to the sensor, allowing it to measure how high the water level is. The flooding event and other construction work near the site have changed the shape of the channel and altered this relationship between water level and river discharge, Raimer indicated. USGS staff are working to rebuild accurate estimates by taking manual river flow measurements of the river at different water levels, Raimer stated, which can then be used to establish the correct correlations between water level and discharge.

The Colorado River, from one viewpoint, is a mess.
The iconic waterway, fundamental to the region’s modern existence – its desert metropolises, its high-tech industries, its agriculture, and its recreation economy – is on the verge of crashing. A two-decade drying trend, aided by carbon pollution in the atmosphere and water use that exceeds supply have nearly drained the basin’s liquid savings accounts.
Nature is now threatening to overwhelm human interventions. Lake Powell is 28 percent of its capacity. Lake Mead, just 24 percent. Climate pressures abound in these hot, dry times. A March heat dome obliterated temperature records. Snowpack was the worst on record. At least five fires larger than 25,000 acres are currently burning in the parched basin.
The basin’s seven states, unable to find consensus on how to live with a shrinking supply, are deadlocked after four years of attempting to negotiate the river’s management rules. State and federal authorities are deciding how much less Colorado River water will be available, anticipating that the reductions will hurt. Knowing that water enables economic growth, they don’t want to be viewed as selling out their constituents.
Look closer, however, and the narrative of warring factions fades a bit. At the local level, water managers are collaborating to ensure residents and businesses have adequate water supplies. They are signing multiparty deals and pursuing joint projects to share resources and keep water flowing to homes and businesses. Such dealmaking is not a remedy to all that ails the basin. But it is viewed as essential in a time of deep climate uncertainty and anxiety.
In June, six water suppliers in Arizona, California, and Nevada signed a memorandum of understanding with the Bureau of Reclamation, a federal agency, to facilitate interstate exchanges of desalinated and recycled water for Colorado River water. The exchanges, taking advantage of spare treatment capacity on the California coast, would introduce new water into a depleting basin.
Earlier this spring, Phoenix, Tucson, and other Arizona water users announced a venture to create an emergency reserve of water for cities facing shortages and to simplify voluntary water transfers in the state – “an easy button” to move water to where it is needed, said Max Wilson, Phoenix’s water resources management adviser.

And in New Mexico, Santa Fe’s water utility is in early talks with neighboring pueblos about joint infrastructure for storing water underground, recycling water, and sharing water between systems in case wildfire pollutes a water source and renders it unusable.
“Cities have the ultimate responsibility to make sure there’s tap water,” said Kathryn Sorensen of Arizona State University and the former director of the Phoenix water utility. “And that means they have to be constantly vigilant and constantly innovate and constantly find new arrangements and new supplies.”
These arrangements, while not a new development, have taken on greater significance as the American West struggles through record heat and aridity this year that is an indicator of worsening water supply challenges in the drying region. Based on a decades-long track record, these arrangements also illustrate that neighbors helping neighbors can be a cost-effective form of climate adaptation.
“It makes sense to me that this happens at the local level because that’s where the risk is,” Sorensen said. She cited the Central Arizona Project, or CAP, as another example. CAP delivers Colorado River water to Phoenix, Tucson and other customers in the state’s populous midsection.
“The risk to the CAP of there not being water in the canal is that the CAP doesn’t deliver water to its contractors and subcontractors,” she said. In other words, a contractual failure.
But for the cities who hold those contracts? A failure to deliver water would hasten a public health and economic crisis. “The risk to a city is there’s no tap water,” Sorensen said. “And that’s just a totally different level of risk. So you see these types of innovations happen at the level where the risk exists.”
Collective Action
Partnerships do not happen spontaneously. They are the product of months and years of discussion, negotiation, and relationship building.
“The biggest challenge is communication, understanding the needs of your partners and clearly their sensitivities,” said Bill Schneider, the Santa Fe water resources manager.
Schneider is part of discussions with four pueblos in the Santa Fe area on joint water infrastructure projects, including water recycling and underground storage.
One clear possibility is that Santa Fe could connect its water system to the Pojoaque Regional Water System, which will serve Pojoaque, Nambé, San Ildefonso, and Tesuque pueblos with Rio Grande water.
Connecting neighboring systems is a form of insurance, Schneider explained. Wildfires are a perpetual risk in the watersheds of northern New Mexico. If a severe wildfire sends ash and debris into the Rio Grande, the polluted water could force water systems to shut off their river intakes. It has happened before on the Rio Grande. The Albuquerque Bernalillo County Water Utility Authority had to close its intake for two months in 2011 after the Las Conchas fire. With an interconnected system, water could be delivered to the pueblos from Santa Fe’s other sources, which include the Santa Fe River and groundwater.
Due to the high cost of building infrastructure, system interties and similar partnerships make financial sense, Schneider said. “It means you don’t have to go out and build an entirely new system.”
These infrastructure arrangements already exist in many places, but especially in Arizona. Nevada, for instance, has banked part of its Colorado River allocation underground in Arizona for more than two decades.
A decade ago, when Sorensen was the director of Phoenix Water Services, Phoenix and Tucson signed a trailblazing water deal. It allowed Phoenix to bank some of its Colorado River water underground in Tucson. When the water is needed, Tucson will be able to pump the groundwater and, in exchange, Phoenix will take some of Tucson’s share of Colorado River water. The deal, which has not yet had to be exercised, makes the most efficient use of the water treatment capabilities and infrastructure in the two cities.
That agreement, Sorensen said, paved the way for other exchange partnerships in central Arizona. Mesa, in a project completed this year, provides treated wastewater to the Gila River Indian Community in exchange for 8,000 acre-feet of Colorado River water. (An acre-foot – 326,000 gallons – can supply about 3.5 households in urban Arizona for a year.)
In Sorensen’s view, dealmaking is fundamental for utility leaders.
“They’re good horse traders, right?” she said. “That’s part of the job. ‘How can we make a win-win exchange or trade here that makes everyone happy and maximizes the resource?’ The water managers are really good at that.”
The latest iteration is the Secure Water Arizona Program, or SWAP, that Phoenix and Tucson are developing with other central Arizona cities.
Details are still being finalized, but the program will have three components. One is an emergency reserve of water that cities can tap as a last resort. A second piece is facilitating water exchanges between willing sellers and willing buyers. The third element is what Wilson calls “the sandbox” – a forum for collaboration on the next generation of central Arizona water projects.
The idea, said Max Wilson, the Phoenix water adviser, is a form of mutual aid. “At its core, the assumption of the SWAP is that water users shouldn’t be letting other water users go dry.”
Even with the benefits, Wilson acknowledged that collaboration needs to be carefully calibrated.
“People don’t want to see water being forcibly reallocated, for sure,” he said. “People don’t want to see their water going to uses that they necessarily wouldn’t see as beneficial. But when people have legitimate needs, I’ve been really impressed by how the water user community has come together and been willing to say, ‘Let’s talk and let’s figure out what a potentially mutually beneficial solution to those needs could be.’”
Attorney: ‘In order to evaluate the current state of the aquifer in context, you would need to know how much the aquifer holds, wouldn’t you?’
Engineer: ‘I don’t believe so’
How much water is in the storage area of the unconfined aquifer? That was a question SWAG attorney Brad Grasmick posed to state Division 3 Water Engineer Craig Cotten and left the Alamosa water court hanging on at the conclusion of Wednesday’s day in water court.
In his first full day of cross examining Cotten, Grasmick covered a variety of territory from surface water credits to the one-to-one pumping feature of the new plan to Cotten’s responsibility to administer the plan. At times he got so deep into the proverbial weeds in grilling Cotten that Gonzales spoke of his own frustration in trying to follow along.
“You’re losing me on focus,” Gonzales told Grasmick as he called for a lunch break.
The question Grasmick posed at the end of his nearly six hours of cross examination offered a unique exchange. Grasmick started by saying he hasn’t seen a figure on how much water the unconfined storage area can hold. It’s been well-established in the testimony of Cotten and HRS hydrologist Matt Seitz that the unconfined aquifer functions as an underground reservoir and was built up initially through early subirrigation practices and then canal diversions.
Storage readings of the unconfined aquifer that go back to 1976 show it responsive to strong spring runoff seasons but now transitioning through the process of aridification to the San Luis Valley floor as it adapts to 25 years of drought and the lack of consistent snow melt.
“Nor have I seen how much water is presently in storage in the unconfined aquifer. Do you agree with that?” Grasmick asked.
Cotten: “Well, we have the Davis Engineering service change in storage, so we know the change in storage from 1976. The total amount of water in storage at the present time, I’m not aware of that number.”
Grasmick: “OK. In order to evaluate the current state of the aquifer in context, you would need to know how much the aquifer holds, wouldn’t you?”
Cotten: “I don’t believe so.”
Grasmick: “Well, and you would also need to know how much is in the aquifer in order to evaluate this decline in context, correct?”
Cotten: “No, I don’t believe so.”
Grasmick: “Well, as an example, if there was a one million acre-foot decline in storage, that’s very different if the reservoir holds one and a half million acre-feet than if it holds say four million acre-feet, isn’t it?”
Cotten: “There again, I don’t believe so if you’re shooting for an actual storage amount, change in storage amount as your goal.”
In the Fourth Amended Plan of Water Management under consideration, Subdistrict 1 is charged with recovering the unconfined aquifer to a “sustainable” level of negative-200,000 to negative-400,000 acre-feet of water storage.
Grasmick continued his questioning: “So you disagree that contextual analysis of data is necessary to ensure that it’s not misinterpreted?”
Cotten: “I don’t agree that we need to know the total storage or the actual storage right now in developing this plan.”
The exchange continued for about another three minutes before Grasmick began to shift to another subject and Gonzales intervened.
“I apologize. I think it’s been a long day, so I think it’s probably a good place to stop,” the judge said.
The water trial on the Subdistrict 1 Fourth Amended Plan of Water Management resumes Thursday [July 9. 2026].

Against the recommendation of an advisory board, Pitkin County commissioners on Wednesday gave preliminary approval to buy more water to boost flows in the often-depleted Roaring Fork River.
Commissioners approved on first reading a resolution and ordinance to spend $442,500 to buy 4.68 shares from the Twin Lakes Reservoir & Canal Co., which is about 3.5 acre-feet of water, according to a staff memo. The deal is in addition to the $6.5 million Pitkin County already agreed to spend earlier this year for about 71 acre-feet from Twin Lakes and another ditch company.
Twin Lakes collection system
The water is currently taken across the Continental Divide to the Arkansas River basin to be used by entities on the Front Range. The deal would allow the water to be released out of Grizzly Reservoir to Lincoln Creek and could help boost the Roaring Fork through Aspen and upstream, which suffers from low flows in dry years.
“I think it’s really critical that we purchase water rights when we can, and this is an opportunity that we can, and we should,” District 1 Commissioner Patti Clapper said.
Pitkin County has long had a goal of increasing the amount of water in the Roaring Fork, a river that has about 40% of its headwaters diverted to the eastern side of the state through the Independence Pass Transmountain Diversion System to be used by Colorado Springs, Pueblo and Aurora. These diversions can often contribute to the depletion of the Roaring Fork through Aspen, and purchasing Twin Lakes water represents a rare opportunity to return water to the Western Slope.
Commissioner Greg Poschman said he supports acquiring the water shares.
“I think it’s great that we are doing this,” he said. “I know it’s expensive; there are some raised eyebrows about that, but I think this is something we have to do.”
Poschman added that he was concerned that the Healthy Rivers board members recommended against buying more water and said he would like to fully understand their reasons. County staff said they were trying to schedule a joint meeting with the Board of County Commissioners and the Healthy Rivers board in August.
Members of the county’s Healthy Rivers board, which advises the BOCC, are concerned that the water will have a small impact on river health but a big impact on the program’s budget. The board held a special meeting June 25 to consider acquiring the shares and approved a motion saying the water yield would potentially be only 1 additional cubic feet per second for two days.
“Additionally, the deleterious effects of the purchase price on the long-term fund balance of the Healthy Rivers Fund will reduce the Healthy Rivers Program’s ability to support programs to address other ballot measure mandates, including water quality, ecological health, recreation opportunities, wildlife and riparian habitat, and promoting water conservation,” the motion reads.
The motion goes on to say that in the future, the county should implement a framework for evaluating the true value of water shares to the Roaring Fork.
At Wednesday’s meeting, County Budget Director Connie Baker told the BOCC that the Healthy Rivers board will have to trim or reallocate about $500,000 from next year’s budget to account for the combined impact of this year’s two water purchases.
Healthy Rivers board member Ned Andrews said he is against the purchase, citing the impact that it will have on the program’s budget.
“None of the analysis or details that would justify such a purchase or a strategy going forward has been done,” Andrews told Aspen Journalism. “I think before you commit essentially a quarter of your budget for the next 15 years, you’d want to have an analysis that shows you what could be accomplished. My gut feeling is that it wouldn’t really accomplish much.”
Andrews also opposed the earlier, larger water share purchase, although the rest of the Healthy Rivers board was supportive.
At their regular June meeting, Healthy Rivers board members went through the budget line by line and considered where they could trim, although those cuts have not yet been finalized.
Spending big bucks in an effort to rescue rivers is not new for Pitkin County, which has spent at least $3.5 million on the Roaring Fork River Park in Basalt, including a water court battle to secure the water right for recreation, several redesigns of problematic waves, and improvements to the riverbank and boat launch.

Bond for original purchase approved
The BOCC at Wednesday’s meeting also approved issuing a bond for the original purchase of Twin Lakes shares. That deal cost the county $6.5 million, although only 45 of those acre-feet represent Western Slope water that is currently diverted to the Front Range. The county plans to sell or trade the other 26 acre-feet, which is owned by the Fountain Mutual Ditch Co. in El Paso County and decreed for use on the east side of the divide.
The 45 acre-feet of water can be released down the Roaring Fork during the irrigation season when flows are low, and it must be used by a downstream water user on the Colorado River before the town of DeBeque. Instream flow for the benefit of the environment is not a decreed use of the water.
This year, according to Colorado Water Resources Division 5 Engineer Tyler Benton, at least some of Pitkin County’s Twin Lakes water was released as part of the Colorado River Water Conservation District’s emergency substitute water supply plan, which the district enacted in response to this year’s historic drought. Benton said he expects the River District to provide a full accounting of how much Pitkin County water has been released Friday.
Grizzly Reservoir is currently drained for dam maintenance, which may have affected how much water could be released under the River District’s plan.
At a time when drought impacts are being acutely felt across the state and climate change continues to rob rivers of their flows, for some, the unique opportunity to put water back into a depleted stream is worth the cost.
“This is expensive water, but it’s the only water you can get up at the headwaters of the Roaring Fork,” said Pitkin County Deputy Attorney Anne Marie McPhee. “So that scarcity makes it more valuable.”
The issue is scheduled for a public hearing and second reading July 22.
The fire situation in the Four Corners area is not improving. The weather remains hot, dry, and windy, and this week’s forecast calls for more of the same. Next week may even be hotter, if longer-range models hold. Meanwhile, air quality has deteriorated in some places that previously seemed to avoid the worst of the smoke. The good news is that the Fourth of July weekend came and went without any new major fire starts in the region.
So far this year some 37,209 fires have burned through about 3.3 million acres, according to the National Interagency Fire Center. That’s the second highest acreage for the first half of the year in the last decade.
Here’s a rundown of some of the Four Corners area fires. By no means is this a complete list.
The Babylon Fire, burning in the higher elevation parts of Bears Ears National Monument in southeastern Utah, had grown to over 96,000 acres by Monday night, making it the nation’s largest active blaze (the Cottonwood Fire in the western part of the state has gone through about the same amount of acreage, according to Watch Duty). The two are also tied for the fourth largest fires in the state’s recorded history. The Babylon Fire is at 0% containment, with the most active area moving up the west slope of the Abajo Mountains, between Shay Mountain and Mount Linnaeus. Air tankers are pulling water from Lake Powell, and officials are asking boaters to avoid the area between Dangling Rope and Rainbow Bridge.
Closed public lands include: The Needles District of Canyonlands National Park, Manti-La Sal National Forest lands within the Monticello Ranger District, and BLM lands in the Indian Creek Corridor, Beef Basin, Dark Canyon, and the Sweet Alice Wilderness Study Area. Still Open: Natural Bridges National Monument, Cedar Mesa, Grand Gulch, and other lower elevation areas in the southern reaches of Bears Ears National Monument.
The Ferris Fire along the Dolores-Montezuma County line in southwestern Colorado initially burned in a northeasterly direction toward the Disappointment Valley. Then the winds shifted and the most active front of the fire curved back to the northwest, crossing the Ponderosa Gorge of the Dolores River, and is within about 12 miles of the town of Dove Creek. As of Monday night the fire was at 51,622 acres and 22% containment.
The Gold Mountain Fire north of Ouray, Colorado, has burned across almost 29,300 acres of San Juan Mountain high country and was 2% contained as of Monday night. Firefighters on Monday conducted strategic backfiring operationseast of Ridgway to provide more protection for structures in that area. There is a chance of thunderstorms this afternoon and evening, which could bring dry lightning along with gusty and erratic winds, with high temperatures reaching the high 80s and low 90s.
The Pocket Fire north of Sedona, Arizona, has reached 26,442 acres and was at 48% containment as of Monday night. Forecasters are predicting more hot and dry weather today, with the mercury topping out around 100° F and sub-20% relative humidity.
On July 6, the Arizona Department of Environmental Quality approved Energy Fuels’ request to amend its aquifer quality permit for a groundwater monitoring well at its Pinyon Plain Mine near the Grand Canyon. The change raises the allowable concentration of arsenic from .050 milligrams per liter to .055 milligrams per liter and the associated alert level from .040 to .050 mg/l.
The Havasupai Tribe strongly condemned the change in a written statement, calling the approval a “profound attack on the Tribe’s inherent responsibility to guard and protect the waters of the Grand Canyon.”
Energy Fuels asked for the revision — and ADEQ granted it — after finding that construction of the mine’s shaft had created a hydraulic sink that allowed naturally occurring arsenic — a known toxic substance — to move toward the facility’s perimeter wells, putting them in violation of their permit.
So, regulators simply altered the permit’s limits and, according to the tribal nation’s statement, “chosen to weaken environmental protections instead of strengthening them.”
Dr. Bradley K. Esser, a retired Lawrence Livermore Laboratory scientist, submitted technical comments on the proposed revision last year. He cast doubt on Energy Fuels’ hydraulic sink explanation, and demonstrated that the arsenic concentrations detected in the monitoring wells are far higher than regional natural background levels. He posited that it was far more likely the elevated arsenic concentrations came from sump water from the mine’s workings contaminating the groundwater.
Uranium, arsenic, and lead concentrations shot up in the Pinyon Plain Mine’s “sump water,” or groundwater that had flowed into the mine shaft, after active mining began in 2023. While an independent scientist acknowledges that it’s possible elevated arsenic levels in perimeter monitoring wells are the result of a mining-related hydraulic sink pulling naturally occurring arsenic to the wells, he posited that it’s more likely that sump water made its way into the groundwater in the wells.

Monsoon season officially kicked off in the Southwest in the middle of last month, but it has yet to bring significant amounts of moisture. Earlier forecasts predicting higher than average precipitation beginning later this month are still in place for some parts of the West, but they likely will be accompanied by above-normal temperatures just about everywhere.
Next week isn’t looking so hot for fire-dousing moisture in the Southwest, but after that the chances of above-normal precipitation start climbing.

Reporting Highlights
Certainty on the River: Tribes have negotiated a settlement to resolve the largest outstanding claim to the Colorado River, while providing billions of dollars for water infrastructure.
Upper Hand: Colorado, New Mexico, Utah and Wyoming — the Upper Basin states — are resisting the deal because it allows the Navajo and Hopi to lease water outside their reservations.
Unfulfilled Promise: It has been 118 years since the Supreme Court ruled that the federal government owes tribes water, but many are still fighting to resolve their rights.
These highlights were written by the reporters and editors who worked on this story.
A deal to bring Colorado River water to Native American communities in northern Arizona, where a third of homes lack running water, is being blocked by neighboring states, caught up in a broader battle over how to divide the dwindling river.
The largest tribal water rights settlement in U.S. history — the product of decades of negotiations to secure water for the Navajo Nation, Hopi Tribe and San Juan Southern Paiute Tribe — was on the verge of being realized before Colorado, New Mexico, Utah and Wyoming stepped in to oppose it being codified by Congress.
Those four states, known collectively as the Upper Basin, are at a stalemate with the Lower Basin states of Arizona, California and Nevada over new rules governing how they share the Colorado River, a key water source for nearly 40 million people. Congress and the White House, under both Democratic and Republican leadership, have declined to approve the settlement until all parties reach an agreement.
For 83-year-old Marilyn Tewa, the stalemate means her family will continue to go without running water. Tewa serves on the Hopi Tribal Council, where her duties include working on the water rights agreement, but her village of Mishongnovi, on the tribe’s northern Arizona reservation, lacks indoor plumbing.
Every other day, she loads 5-gallon buckets into her pickup and drives 5 miles to a windmill originally built for livestock that draws untreated water from underground.
“That’s what keeps us alive,” Tewa said, tapping the spigot on a May afternoon.
Back home, Tewa bustled about her kitchen while her daughter kneaded dough for dinner. There’s no faucet in the kitchen, which is decorated with a framed American flag and a painting of a katsina, a figure with spiritual significance in Hopi culture. Instead, the family stores water in large plastic containers. Because of the lack of indoor plumbing, the Tewa family and its neighbors use portable toilets that stand among the houses.
If passed into law, the Northeastern Arizona Indian Water Rights Settlement Actwould resolve the largest outstanding claim on the Colorado River while providing about $5 billion in federal funding to build infrastructure to transport the water across the reservations. The legislation would also go beyond water rights, creating a reservation for the San Juan Southern Paiute. The tribe’s effort to secure a permanent homeland was added to the settlement due to their difficulty getting it through Congress independently.
“That’s my prayer,” Tewa said, “that we get this settlement through for all three tribes.”

The tribes need pipes, pumps and treatment plants to use the water secured through the settlement. To defray the cost beyond the federal government’s expected contribution, the Navajo and Hopi plan to lease some of their water rights, almost certainly to growing towns around Phoenix. The towns would pay to use the tribes’ water for a set number of years.
While the Lower Basin states support the settlement, the Upper Basin states have latched onto this provision in particular as they stand in the way of the settlement.
The Colorado River’s upper and lower basins don’t precisely follow state borders. Some states have portions in both sections, and the line dividing the two basins cuts across northeastern Arizona and directly through the Navajo reservation. If water moves across that line, they argue, the rules governing the river give them veto power over the settlement. (It’s an open legal question whether approval from all seven states is necessary.)
The Upper Basin states fear that, in the future, water they currently control might be leased on an open market. They view any monetary transaction that moves water downstream as setting a precedent that could allow the highest bidder — possibly thirsty cities with money such as Los Angeles, Phoenix and Las Vegas — to buy vast quantities of their water.
In an effort to assuage that concern and close the deal, the Navajo and Hopi made major concessions over the volume of water and length of time they could lease. The tribes also offered to leave some of their water in one of the river’s drought-depleted reservoirs to help keep water levels high enough that it could continue flowing downstream. But the Upper Basin has not wavered in its opposition.

ProPublica and KJZZ News-Phoenix reached out to the governor, senators and lead negotiator from every Upper Basin state for comment. Utah’s and Wyoming’s lead negotiators deferred to the letter they co-signed. A spokesperson for New Mexico Gov. Michelle Lujan Grisham said in a statement that the tribes addressed most of the state’s concerns but that questions remain as to whether the water that the tribes would lease to Arizona cities could be counted as part of what the Upper Basin states are legally required to send to the Lower Basin. “New Mexico remains committed to finding a workable solution,” the spokesperson said.
A spokesperson for Colorado Gov. Jared Polis also said the state is “committed to finding a path forward” and pointed to the letter that Becky Mitchell, the state’s lead river negotiator, submitted to Congress. Mitchell wrote that the settlement’s leasing provisions violate laws governing the river and that the state was concerned about what the sale of water across the basin would mean for “the security and certainty” of Colorado’s share of the river.
Heather Tanana is an assistant professor at the University of Denver’s law school, where she focuses on federal Indian law. She is also a citizen of the Navajo Nation and said the Upper Basin is “trying to hide behind” how the river has traditionally been managed rather than find a way to give the tribes access to a resource that is rightfully theirs and one that they need to survive.
“It’s a fundamental human rights issue,” she said.
While negotiations drag on, the three tribes continue waiting for water they say will help them to build more housing, grow sustainable economies, better protect public health and preserve cultural practices.
The Hopi believe their ancestors return as clouds to bring the rain that nourishes their corn, but drought is wracking the region. An overreliance on groundwater has dried up springs that have been used for ceremonies and agriculture for centuries. When the settlement brings more water to the reservation, Tewa said, aquifers will have a chance to recharge, restoring the springs.
“I’m speaking on behalf of my children, my grandchildren and their children that haven’t come yet,” she said. “I hope, in the future, that they will have water.”

Fighting for Water Since Elvis Was on TV
That the settlement even reached Congress seemed like a small miracle to those involved.
If the tribes were to use every drop to which they are entitled, the system of sharing the river that supports more than $1 trillion in annual economic output would collapse.
“Everybody’s getting free Navajo, Hopi and San Juan Southern Paiute water right now. The seven basin states are all benefiting in the absence of a settlement,” said Ethel Branch, a former Navajo attorney general who was involved in the negotiations, adding that the water had been “stolen for over a century.”
In 1908, the Supreme Court ruled that, if the federal government confined tribes to reservations, then it owed them enough water to sustain an agrarian economy on that land. But securing that promised water, referred to as “Winters rights,”has proven arduous.
Tribes were excluded from the compacts that apportioned the river. The Navajo in particular were barred from joining a seminal case quantifying other users’ rights, and members of the tribe themselves rejected a proposed settlement in 2012 when they viewed the deal as unfair. So the tribe went back to the Supreme Court, asking that the justices force the federal government to quickly settle the claims. The Navajo once again lost, with the court’s majority deciding that their treaty with the U.S. didn’t require the government to take any “affirmative steps” to deliver the water it owed the tribe.
“At each turn, they have received the same answer: ‘Try again,’” Justice Neil Gorsuch wrote of the Navajo in his dissent. “When this routine first began in earnest, Elvis was still making his rounds on The Ed Sullivan Show.”
Arizona politicians and tribal leaders have since concluded that they needed to combine all three tribes’ claims to finally settle their rights.
That was no simple feat. The Navajo and Hopi have long had a contentious relationship. Underlining their thorny partnership, leaders of various tribes around the region have accused Navajo, the largest tribal nation in the U.S., of flexing their political strength to the detriment of other tribes.

But Navajo and Hopi struck a deal, and Arizona moved off its bargaining position. Now in lockstep, the settlement’s supporters turned to Congress, only to hit more roadblocks: The House of Representatives balked at the spiraling price tag to fund the deals; presidential administrations were unwilling to expend political capital on such settlements; and more than a dozen settlements are in the works, clogging the system. (No settlement has been enacted since 2022.)
“Partisanship has gone to a new low in this country, and Indian water settlements have gotten swept up into that,” said Pam Williams, who spent about two decades as director of the Secretary’s Indian Water Rights Office in the Department of the Interior before she retired last year.
In November 2024, as President Donald Trump prepared for his return to the White House, the tribes believed they had an opening to get their settlement through Congress while President Joe Biden was still in office.
Navajo leadership had supported the Democratic presidential ticket and feared the incoming administration would be vindictive toward them.
Every basin state’s lead negotiator, tribes’ staff and a federal representative descended upon the Arizona Department of Water Resources’ offices in Phoenix for what several attendees described as a “Hail Mary.” At the meeting, the Navajo offered a major compromise: limiting how much water they could lease and for how long they could lease it.
But the Upper Basin states showed up with a list of grievances, multiple attendees told ProPublica and KJZZ News-Phoenix, and weren’t interested in negotiating over the Navajo leasing concessions.
“It’s difficult for the Upper Basin to wrap their heads around this settlement,” said Tom Buschatzke, Arizona’s Colorado River lead.

In March 2026, leaders from the tribes traveled to Washington for a Senate hearing where they made an impassioned plea for Congress to pass a version of the bill that now included the concessions they had offered in the Hail Mary meeting. Sen. Lisa Murkowski, the Alaska Republican who ran the hearing, expressed support for the settlement but worried its $5 billion price tag was too high, a concern echoed by an Interior Department official who testified. (The tribes and department are currently negotiating to shrink that cost.)
All four Upper Basin states submitted comments opposing the settlement. Their main concerns were about the ability to lease across the basin and whether the water for the settlement would be counted against the upper or lower division of the river.
Leasing would last only as long as it’s needed to pay for infrastructure to distribute their newly acquired water, said Navajo President Buu Nygren. It would not set a precedent, he said, because no other tribe straddles both basins.
“We shouldn’t be punished for being in two basins,” Nygren said, “because other tribal nations, other settlements have been able to lease water.”

“How Precious Water Is to Us”
During the decades that the tribes fought to access their water, they helped quench the thirst of growing cities in the Colorado River Basin.
A water intake plant on Navajo land drew from Lake Powell to cool the nearby Navajo Generating Station. The coal plant powered pumps for the Central Arizona Project, the 336-mile series of canals that sends Colorado River water to Phoenix and Tucson.
The power station shut down in 2019, and the intake plant was handed over to the Navajo for the iiná bá-paa tuwaqat’si pipeline, which means “for life” in Diné and “water is life” in Hopi, to deliver water to the three tribes. But for now, the massive pumps remain mothballed, the building sitting musty and dark like a tomb, and the pipeline remains an engineering schematic, waiting for funding from the stalled settlement.
The irony is not lost on tribal leaders, they told ProPublica and KJZZ News-Phoenix: After helping deliver water beyond their lands, they are now blocked from using that same water and infrastructure to sustain their communities. The insult is compounded, they said, by the fact that water use is drastically lower on reservations.
“It’s not about green-grass lawns or golf courses or swimming pools,” said Crystalyne Curley, speaker of the Navajo Nation Council. “It’s just basically turning on the faucet and getting water to boil eggs for your children or turning on a faucet to wipe and clean the table or washing your hands after butchering a sheep.”

For the San Juan Southern Paiute, the settlement is also about having a permanent homeland. They have no reservation but struck a deal with Navajo in 2000 to transfer some of its land. Since the tribes already reached an agreement, it’s an uncontroversial proposition. But, without political clout to get Congress to take it up, the land transfer was pulled into the water settlement.
“During the COVID era, it took a lot of the tribal elders, and there are only a handful that saw the treaty signed and are really wanting to see this before their time is up,” said San Juan Southern Paiute Vice President Johnny Lehi Jr., whose father signed the 2000 agreement. Finally securing a reservation, he said, means the ability to build housing and develop an economy for a tribe that currently rents its government building.
Nearby, on the Hopi reservation, Councilmember Marilyn Fredericks grabbed a pair of hiking poles, donned a hat with a roadrunner pin on it and set out from her village on a recent spring afternoon. To stay fit as she grows older, she walks up and down the hand-carved steps of a terraced garden that used to produce food for her community.
Seven natural springs once fed the garden, but only two still flow. Ponds that stored their excess sit dry, stains on the rock now just a memory of the water. It’s been six years since there was enough to plant.
The settlement would fund a pipeline that would be “our umbilical cord,” Fredericks said. Future generations of Hopi have a right to clean, reliable water, she said. “This is evidence of how precious water is to us.”

The full impact of this past winter’s record-low snowpack is rearing its ugly head in the form of:
Record-low spring stream flows.
Low reservoir storage levels.
An empty reservoir.
And one incredibly rare statistic.
On June 17, Denver Water’s reservoir system hit its peak storage level following a diminished spring runoff.
Water levels in the utility’s reservoirs collectively hit 81% of the system’s storage capacity — the second-lowest peak storage level on records dating back to 1983, considered the beginning of the modern Denver Water collection system.
“Peak storage” is the moment, or day, when the utility’s collection system holds the most water it will hold for the next year. It’s akin to topping off a swimming pool once a year in June to carry the pool through the next year of use.
Typically, the “peak storage” moment happens in mid-June, after the spring runoff.
But in 2026, due to the record-low winter snowpack and low spring runoff, Denver Water’s collection system held more water on Jan. 1 — 83% of capacity — than on June 17, as the runoff dwindled and storage levels inched to 81% of capacity.
There’s only one other year since 1983, when the Strontia Springs Dam was completed, that Denver Water’s storage was higher in the dead of winter than the dawn of summer — the drought year of 2002.
“Having our highest amount of water happen in January is incredibly rare. It speaks to how little snow we saw this winter and the impact of the record-setting warm weather,” said Nathan Elder, Denver Water’s manager of water supply.
“We’ve seen many records fall this year, and unfortunately, they were not good ones.”
Dillon Reservoir reached 80% capacity on June 17, the highest elevation it is expected to see in 2026. Dillon is the largest reservoir in Denver Water’s collection system, storing roughly 38% of the utility’s water supply. Photo credit: Denver Water.
During the spring peak, the amount of water stored in Denver Water’s reservoirs typically hits an average of 97.5% of capacity.
And since 1983, the utility’s peak storage levels have hit at least 95% of capacity (considered sufficient for normal operating conditions) in all but six years.
“Ideally, we like to top off our mountain reservoirs during the spring runoff, but this year our storage levels came up well short,” Elder said.
Record low ‘paycheck’
Why do water managers focus on peak storage numbers?
The peak reservoir storage figure is critical to determining how much water is available until next year’s spring runoff. It’s comparable to a family determining how much money they have to pay the bills until the next paycheck comes through.
“The spring runoff is our annual paycheck from Mother Nature,” Elder said. “The water filling our reservoirs is the cash that fills our bank account. But in our case, that paycheck only comes once a year — and this year we didn’t get anywhere close to the normal amount.”

This year’s meager paycheck was reflected in the record-low peak flows on the rivers and streams that feed Denver Water’s reservoirs.
Mountain snowmelt accounts for 90% of Denver Water’s supply, which provides water to 1.5 million people in metro Denver.
In Summit County, Denver Water recorded this year’s peak stream runoff into Dillon Reservoir at just 404 cubic feet per second, or cfs, on May 29. That’s a record-low “peak inflow” and less than a quarter of the normal peak inflow into the reservoir of 1,750 cfs, which typically happens on June 7.
In Park County, the South Fork of the South Platte River experienced a double-whammy, with record-low flows that occurred abnormally early in the season.
Flows on the South Fork peaked on March 25 at a record-low flow of just 18 cfs. That’s 15% of the normal peak flow of 120 cfs, which usually happens on June 10.

“In a typical year, the rivers and streams start rising in late-April as the snow starts to melt, then they peak in early June, and then they start to ease back to normal flows throughout the summer,” Elder said.
“This year the runoff started about six weeks early in March, and the normal spring surge of water we usually see was basically nonexistent.”
Reservoir impact
The results of the record-low spring flows are having a significant impact on three of Denver Water’s most popular reservoirs.
Dillon Reservoir in Summit County topped off on June 17 at 80% of capacity, with water levels about 18 feet below normal for this time of year. Water levels are expected to drop over the next year until the 2027 spring runoff — hopefully more boisterous than this year’s meager flow — begins.

In Grand County, Williams Fork Reservoir topped off June 21 at merely 53% of capacity, about 35 feet below normal for this time of year and forcing the closure of the reservoir’s boat ramp.

Because of the low snowpack, Denver Water also dipped into its emergency water supply at Antero Reservoir in Park County.
Using water from Antero Reservoir is only done in extremely dry years. It’s comparable to someone having to dip into their 401(k) savings to pay bills until their next paycheck.
Denver Water moved water out of Antero this spring and sent it downstream to Cheesman Reservoir to avoid losing water in shallow Antero due to evaporation.

Early forecasts for the abysmal spring runoff and low peak storage were two factors that led Denver Water to issue a Stage 1 drought declaration in March.
The declaration, which calls on customers to reduce water use by 20% and includes mandatory watering restrictions of two assigned days per week, seeks to stretch existing water supplies until next spring’s paycheck is deposited in the reservoirs.
“While the reservoirs are low this year, they are doing what they were built for, which is to help us get us through a dry year,” Elder said.
“We hope customers notice the low reservoir levels and take steps to conserve water at home so we can stretch our water supplies over the coming months.”
Today’s Colorado River Delta is a far cry from the lush waterway that thrived before the river was forced behind dams that diverted much of its flow for half a century. Now, with just small amounts of water and funding, stretches of the parched riverbed have been transformed into healthy riparian habitats.

A new report from a University of Arizona-led team of researchers has evaluated the effects of the 2014-2025 controlled water releases along the lower Colorado River in Mexico to restore natural habitat. The report also lays out a roadmap for continuing the current binational restoration efforts. The report was published today by the Center for Colorado River Studies at Utah State University.
“It’s hard to find some good news about the Colorado River, but we believe we have some to share,” said first author Karl Flessa, professor emeritus in the U of A Department of Geosciences. “The lessons learned from more than a decade of work show that a small amount of water can do big things.”
The controlled water deliveries to the Colorado River streambed from 2014-2025 were mandated by two addenda of the U.S.-Mexico Water Treaty of 1944, which governs the allocation of Colorado River water between the two countries. The current addendum expires at the end of 2026.
To ensure the restoration sites continue to thrive, Flessa said sustaining this binational success will require a renewed commitment of water and funding by the United States, Mexico and non-governmental organizations.
The report reveals that bird numbers and diversity have increased since restoration began in 2014. The delta is an important rest stop for birds migrating along the Pacific Flyway. Beavers and other wildlife have also increased.

The restoration of the Colorado River Delta began in 2014, in the form of a so-called pulse flow, a one-time water release from Morelos Dam that lasted 57 days. Before that, the riverbed below Morelos Dam was dry. The pulse flow was conducted to allow researchers to assess the effects on the ecosystem once water returned.
The pulse flow of 2014 kickstarted a concerted, binational effort to systematically restore riparian habitat along certain stretches of the formerly dry river delta. Environmental NGOs, both in the U.S. and in Mexico, developed three designated restoration sites by terrain-shaping and planting of native riparian vegetation, including cottonwood trees, mesquite trees and willows – species that once dominated the landscape when the Colorado flowed through a healthy delta.
In 2019, AZPM produced a story on revitalizing the Colorado River delta five years after the 2014 pulse flow.
“These NGOs actually have nurseries on site, in which they germinate an array of Sonoran Desert riparian plants. Those seedlings are then planted and carefully irrigated according to the habitat needs,” said Martha Gomez-Sapiens, a U of A research scientist and co-author on the study. “In some cases you will see irrigation drip lines that go to each individual tree – a system designed to maximize water efficiency in this desert environment.”
Subsequent creation, irrigation and maintenance of 1,381 acres of riparian vegetation attracted birds and other wildlife. Deliveries to the river channel raised water tables, supported existing vegetation and increased the length of the flowing river.
In addition, local communities have benefited from recreational, educational and job opportunities. All three restoration sites have visitor programs that cater to local communities and schools, and one – the Laguna Grande complex, managed by the Tucson-based Sonoran Institute – even boasts a visitor center. All offer recreational opportunities in a region dominated by water scarcity.
While the pulse flow of 2014 demonstrated the feasibility of revitalizing former habitats with controlled and planned water releases, the authors conclude that releasing large amounts of water during a limited timeframe has limited benefits for a long-term revitalization of the delta.
“Most of the pulse flow water infiltrated into the groundwater before it could be used by new vegetation,” Flessa said. “Since then, we have learned how to use the water more efficiently for restoration of riparian habitat.”
Importantly, the report points out that restoration sites are not self-sustaining. Revitalizing degraded river habitat will require continuing maintenance, occasional water allocations and monitoring.
According to the authors, just 6,890 acre-feet per year, which represents approximately 0.05% of the Colorado’s total annual average flow, would suffice to preservethe existing restoration sites. With a little more water and a little more funding, the number or size of the sites could be increased even more, according to the report.
“Effective and sustainable habitat restoration can be done with a little bit of water, a small amount of funding and a lot of hard work.” Flessa said.
Other co-authors on the report are Eduardo González-Sargas in the Department of Biology at Colorado State University and Roberto Real Rangel, of The Nature Conservancy in Mexicali, Mexico.

A grab bag from my friends and colleagues working on Colorado River issues….
The good news
From friend of Inkstain Karl Flessa (the guy who helped get me started thinking about the Colorado River Delta), a new analysis concluding that despite the terrible hydrology and political difficulties, environmental restoration work in the delta is working:

Historic water shortages are drying out the scenic mountains that lie at the heart of Colorado’s tourist economy, prompting the state to issue emergency orders earlier this month allowing water to be shifted to the towns and ranches most likely to run dry.
The Colorado River District, which represents 15 Western Slope counties, is running the emergency response effort and with financial support from the Colorado Water Conservation Board has anted up nearly $1 million to make sure even towns that can’t afford it, will have access to drinking water should it be needed.
To make the plan work, the river district opted not to lease portions of the water it normally holds in two high country reservoirs, Ruedi in the Roaring Fork Basin and Wolford Mountain, near Kremmling, on a first-come, first-served basis, as it normally does. Instead, the water is being doled out based on community need, with people and food production getting the water first, according to Andy Mueller, manager of the river district.
“We had a number of requests to lease that water out, but a lot of it would have gone to wealthy gentlemen rancher … but it wouldn’t have been for the common good,” he said.
Under Colorado law, water can only be diverted, stored and used for a designated purpose, such as city drinking water, farm irrigation, environmental streamflows, and industrial uses. Water rights are also tied to seasons, with some available only in the winter or summer.
But this spring, the river district, seeking more flexibility than the laws typically allow, went to Colorado State Engineer Jason Ullmann and asked for emergency authorization to use its water supplies differently. The state agreed, giving the district until the end of August to conduct emergency releases.
At the same time, large agricultural water users in the Grand Valley agreed to cut their water use in an effort to lessen strain on the Colorado River, and protect some of the small towns and ranchers who would have been cut off otherwise.
At issue is a special pool of water that lies within Green Mountain Reservoir, near Heeney, known as the historic users pool, or the HUP. The water is meant as a backup source that allows towns to pump wells and divert from streams even when their water rights are not in priority on the giant mainstem of the Colorado River.
But this year, because of the drought, Green Mountain’s HUP isn’t projected to fill, something that hasn’t occurred since the 1960s when the pool was created to protect mountain water users who had junior water rights, according to Ullmann. The emergency order means that even without the backup from Green Mountain, these communities and ranches will be unlikely to have their water supplies cut off.
The Eagle River Water and Sanitation District, which serves Vail and other small towns in Eagle County, has water in the HUP.
Working in the shadow of a nearly snowless winter, the Eagle River District moved early to enact watering restrictions, limiting outdoor use to just two days a week back in April, after March saw temperatures soar to 80 degrees and the patchy snow cover evaporate months earlier than normal.
“The writing was on the wall,” said Siri Roman, CEO of the Eagle River Water and Sanitation District. “This is a benefit of being in the headwaters and being a resort,” she said referring to the headwaters of the Colorado River. “Our whole community is so connected to snowpack and snow-water equivalencies and what that means. By February we knew there wasn’t enough snow to change the picture for us. We wanted to get to the decision-makers early and say the red lights are flashing. We need to prepare for a water shortage this summer.”
Eagle residents took conservation messages seriously
In Eagle, Tom Gosiorowski, the utilities manager, was standing in Brush Creek shooting videos for the town’s Facebook page, letting its 10,000 water customers know that the stream was the community’s only source of water and it wasn’t looking good. Eagle also relies on the HUP for some of its backup supplies.
“We are really wholly dependent on the streamflow and the water that is in the creek. It’s different from the big Front Range utilities” that have reservoirs, he said.
The district is limiting outdoor water use to two days a week and is sharply limiting the filling of hot tubs and swimming pools. Gosiorowski said he expects golf courses to be restricted as well as the summer wears on.
“We could get to a point where they can only irrigate tees and greens on the golf course,” he said. “We’ve never had to reduce use, but this is so extreme that I think there will be some.”
Gosiorowski said the town was still working on worst-case scenario planning for the end of summer, when streams are normally at their driest. “It’s hard to know exactly what’s going to happen. We’ve never experienced a drought to this degree in recorded history.”
Aspen has also enacted two-day-a-week watering and is prohibiting the filling of pools and hot tubs.
Grand Lake, another community that could be impacted by the shortages at Green Mountain, is not showing signs of strain yet, though officials there are concerned about lake levels.
Grand Lake, the deepest natural lake in Colorado, is linked to two other reservoirs, Shadow Mountain and Lake Granby. All three are part of Northern Water’s Colorado-Big Thompson Project. The C-BT delivers water from the Colorado River to 1 million customers and hundreds of farms on the northern Front Range.
Mike Cassio is a citizen activist who tracks Grand Lake’s health and works with a coalition of community groups and water agencies to help manage the system. Cassio said he’s worried about late summer water levels falling.
“We know Mother Nature controls everything,” Cassio said. If levels in Lake Granby and Shadow Mountain fall too low, water quality will suffer and that “will be the biggest issue.”
Kathy Chandler-Henry sits on the river district’s board and is a former Eagle County commissioner. She said the brown hillsides and dusty streambeds are unnerving.
“Before it was never a question,” she said. “There was always snowfall, there was always water. … Nothing like this year, when it was 80 degrees in March in Vail.”
Back in the 1980s, she said she participated in some regional planning efforts to help the Western Slope learn how to manage its growth. That there could be a winter without snow was unthinkable, if not downright funny.
“One planning consultant in the workshop asked folks what it would be like without snow,” she said. “And everyone just laughed.”
Despite this summer’s deep dry spell, water users say they are encouraged by recent light rains and cool weather. Just weeks ago, the HUP was projected to barely fill at all, but now the 66,000 acre-foot pool is rising again. It recently topped 33,000 acre-feet and is expected to move higher, providing some relief.
But Mueller, of the river district, said this summer is a dress rehearsal for what lies ahead as climate change and warmer temperatures continue to hamper mountain snows and spring stream levels.
“We are just beginning to grapple with the impacts of climate change. Science indicates that 30 years from now, this year may be on the wetter side.”
Last month, leaders from across Colorado’s Western Slope celebrated the release of $40 million in federal funding for the Shoshone Water Rights Preservation Project. At a time when Colorado is celebrating its 150th anniversary and our nation approaches its 250th birthday, this investment represents more than a funding milestone; it marks one of the most significant water preservation achievements our state has seen in generations. It also would not have happened without the determination of our congressional representative, Jeff Hurd, who made this project a priority and worked tirelessly to deliver results for the communities he serves. What Rep. Hurd understands is the same thing that has united more than 100 local, state, and federal elected officials and leaders in support of preserving these critical senior water rights: the future of the Western Slope is inseparable from the future of the Shoshone water rights. Protecting these rights protects the flows of the Colorado River, sustains our agricultural heritage, strengthens our recreation- and tourism-based economies, and helps preserve the rural communities that make this part of Colorado unique…
I believe that 150 years from now, our grandchildren’s grandchildren will look back on the Shoshone Water Rights project as a turning point. They will see a generation of leaders who understood what was at stake and chose to act. They will see communities that put aside differences, came together, and made a long-term investment in the future of the Colorado River. History will remember the Shoshone project as a major milestone in the stewardship of our most precious resources. From Western Slope ditch companies and water conservancy districts to local governments, state leaders, and members of Congress, countless individuals are still working together to turn this vision into reality. The lesson is an important one. On the Western Slope, progress happens when we pull in the same direction. It takes communities working in harness together to move mountains and sometimes to move water. And it takes elected leaders like Jeff Hurd who are willing to put their shoulders into that work. The Shoshone project demonstrates what is possible when rural Colorado speaks with one voice about protecting its water, its economy, and its future.

Western Slope lawmakers had harsh words for water managers at a state committee hearing last week, questioning whether Colorado has done enough to avoid a lawsuit with its downstream neighbors.
Colorado Sen. Dylan Roberts, a District 8 Democrat who represents several Western Slope counties, including Eagle, Grand, Garfield, Routt and Summit, asked Colorado’s lead negotiator, Becky Mitchell, whether the people of Colorado should have confidence that negotiations among the seven states that share the Colorado River have put the state in the best possible position. The states have been at an impasse for more than two years without a deal for future management as reservoirs continue to decline to record-low levels.
“My constituents just see fighting and intransigence,” Roberts said. “And it’s concerning to me, especially as a Western Slope lawmaker … that the strategy is just ‘Let’s hire more lawyers; we’re going to court no matter what.’ That doesn’t give me confidence, because I don’t think Colorado fares well when we go to court against Arizona and California and Nevada, throwing our fate to the nine justices on the U.S. Supreme Court.”
The remarks came at Thursday’s meeting of the state Water Resources and Agriculture Review Committee in Denver. Along with Mitchell, in the hot seat were state engineer Jason Ullmann and Amy Ostdiek, interstate section chief at the Colorado Water Conservation Board. The three are employees of the state Department of Natural Resources and have the backing of the Attorney General’s office in negotiations.
Roberts’ line of questioning seemed prompted by recent projections that show river flows dipping below a threshold that could trigger litigation. The Lower Basin states (Arizona, California and Nevada) believe that the Upper Basin states (Colorado, New Mexico, Utah and Wyoming) are bound by the 1922 Colorado River Compact to deliver 82.5 million acre-feet of water over a 10-year rolling average. According to the Upper Colorado River Commission, the 10-year average will dip later this year to about 81.3 million acre-feet because of persistent drought.
Some experts believe that this amounts to a “tripwire” that could trigger a lawsuit from the Lower Basin states (Arizona, in particular, has been openly preparing for litigation) that could result in mandatory cuts in water use for the Upper Basin. Upper Basin water managers don’t subscribe to this interpretation, saying their states are only required not to deplete the river’s flows by more than 75 million acre-feet over 10 years.
Mitchell was reluctant to share details of Colorado’s legal strategy in a public forum, but she answered “absolutely” that her team’s work was putting Colorado in the best position. She said cutting back prematurely just to satisfy the Lower Basin’s interpretation of the century-old agreement would be bad for the state.
“If we initiate curtailment now, that is worse for Coloradans,” Mitchell said. “I think that is an important thing to remember.”
Wracked by drought, climate change and a management crisis, the situation on the river has never been more dire. The current management guidelines expire this year, and in the absence of a seven-state deal to share shortages and operate the nation’s two largest reservoirs, Lake Powell and Lake Mead, the feds are poised to step in. The U.S. Bureau of Reclamation plans to release a more detailed, short-term plan to manage the river for the next two years by mid-to-late summer.
State Rep. Julie McCluskie, a District 13 Democrat, said communities in her district have been living with the incredible angst, anxiety and pain of no snow and low reservoirs.
“The frustration I hear in my community is that we have missed multiple deadlines; they are becoming a funny joke,” McCluskie said. “There is such a fear about the lengthy litigation process, the fear of an outcome that is far worse for Colorado than a compromise that we have some control over.”

Conservation conversation is the ‘bare minimum’
Lawmakers also had strong words for state officials regarding conservation, saying legislators must be involved in the creation of any program.
Colorado has dabbled with pilot conservation programs in the past, but traditional programs that pay farmers and ranchers to temporarily cut back on water use remain controversial. This is especially true on the Western Slope, which has long been the target for these types of programs, and where some worry that they could harm rural communities if not done carefully. After two years of exploring how the state could set up a temporary, voluntary and compensated conservation program, officials shelved the idea in favor of focusing on drought-resilience initiatives.
“Other states out of the seven have very clear and actionable roles for their general assemblies, their legislatures,” McCluskie said. “We have less so, and yet the stakes are so high. So I beg of you, decision-makers, that it is essential that we be a part of those next steps.”

Ostdiek said that any program would need to start slow and make sure it incorporates input from people throughout the state.
“I think that we can continue to assess as we go what we might need from you all, and what a program like that might look like,” Ostdiek said. “I think what we can certainly commit to is continuing this dialogue and continuing the discussion about what we might need to make this a success.”
In 2023, Colorado lawmakers tried to force stakeholders to come up with recommendations on conservation programs by creating a statewide task force, which met 10 times over six months. But the group failed to find a consensus, with some saying it was “premature” to create a conservation program.
As part of a post-2026 framework, the Upper Basin states plan to create a “contribution” pool in Lake Powell, which could be used to help stabilize the system, keeping water levels above critical thresholds to protect hydropower at Glen Canyon Dam and acting as an insurance pool against forced cutbacks. In a May 22 letter to federal officials, the Upper Basin states said they have a goal of saving 100,000 acre-feet by the end of water year 2028, but only if sufficient federal funding is available and hydrologic conditions allow.
Three Upper Basin states have different methods for contributing to this pool: Utah has its own demand management program; Wyoming lawmakers passed a law this year allowing for a conservation program; and New Mexico plans to release water from Navajo Reservoir.
But precisely how — and how much — Colorado would contribute to this pool is unclear. The state’s share of the Upper Basin’s allocation is 51.75%, meaning Colorado could be on the hook for 51,750 acre-feet.
And ensuring that saved water actually gets into a pool in Lake Powell remains part of the problem. Currently, conserved water that stays in the river can just be picked up by a downstream user, with no net gain to Lake Powell. Colorado officials say they do not have the authority to “shepherd” water past other water users to the state line unless it is specifically for compact compliance. [ed. emphasis mine]
Last year, some Delta County ranchers asked lawmakers to take up the issue and pass a law that would address this issue, allowing water users to conserve and get credit for contributing water to a Lake Powell pool. But legislators did not take up a bill in the 2026 session.
Colorado officials told lawmakers they were continuing to explore what a program might look like and whether legislation would be needed.
Roberts said conversations with the legislature should be the bare minimum if Colorado is going to have a conservation program.
“If the department or any agency of the state were to pursue a conserved consumptive use program or demand management program that used state tax dollars to pay for it and did not go through the legislature in a formal process, I imagine that all of us on this panel and many of our colleagues would raise holy hell about the unilateral decision-making coming from Denver about programs impacting all parts of the state,” Roberts said. “So, please, let’s just cut that off at my recommendation. Let’s work together on this.”
Officials opened the hearing by highlighting the impacts of this year’s severe drought on Colorado’s farmers and ranchers, noting how even some of the most senior water users will experience shortages as streamflows dwindle. Orchards in the North Fork Valley and row crops in the Uncompahgre River Valley already have unprecedented shortages.
In response to Roberts’ concerns about the failure to find a compromise among the seven states, Mitchell posed a high-stakes rhetorical question: “I would ask, ‘What else do you think we can give?’”

While the Trump administration 2.0 has so far rexfrained from trying to shrink or eliminate national monuments, its non-executive-branch proxies just keep on trying.This week the 10th Circuit federal appeals court issued a decision keeping alive Utah’s lawsuit challenging Joe Biden’s 2021 re-establishment of Grand Staircase-Escalante and Bears Ears national monuments following Trump 1.0’s shrinkage of the same.
The state and Garfield and Kane counties filed one lawsuit in 2022, with the Blue Ribbon Coalition and other parties filing their own suit. In 2023, a federal court dismissed both lawsuits; that ruling was appealed.
This week’s decision confirmed the dismissal of the Blue Ribbon suit. But it also determined that presidential national monument designations under the Antiquities Act are subject to federal judicial review, and sent Utah’s case back to the district court.

The Bureau of Land Management is moving forward with three travel management plans in Utah that will determine which roads, trails, and areas of the respective field offices’ jurisdiction are open to motorized vehicles. Given that the stated aim is to bring the plans in line with Trump’s recent executive order rescinding restrictions on motorized vehicles on public lands, we can assume that the idea here is to expand motorized access to some remote areas. The plans include:
The Moab Field Office has released preliminary alternatives for the Dolores River Travel Management Plan on about 127,000 acres in Grand County, Utah, east of Moab and abutting the Colorado border. This would include roads along the Utah section of the Lower Dolores River, and on mesas and in canyons on either side of it. Maps of the alternatives can be found here. This one is not yet open to public comment.
The Kanab Field Office has released a draft environmental assessment for its Trail Canyon Travel Management Plan on nearly 330,000 acres in Kane County. It is open to public input.
And the Vernal Field Office has also released a draft review for the Dinosaur North Travel Management Plan. The public comment period is open.

I typically stay away from electoral politics, especially the horse-race part of it and polls and such. But sometimes a particular contest or candidate can provide a lens on bigger trends or phenomena, and so are worth looking into.
The latest race that has caught my interest is the one to replace Sen. Cynthia Lummis, the Wyoming Republican who is retiring at the end of this term. Since it’s Wyoming in 2026, it’s safe to assume the winner will be a Republican (though this wasn’t always the case), meaning the primary is the contest that matters. The front-runner, I suppose, is Rep. Harriet Hageman, the Trump sycophant and MAGA extremist who unseated Liz Cheney back in 2022 after Cheney failed to show adequate fealty to Trump.
But it’s one of her challengers that I’m interested in: Sam Mead. Mead is a fifth-generation Wyoming rancher, comes from a long line of Republican Wyoming politicians, and is the nephew of former governor Matt Mead. Mead is young (36), charismatic, has strong conservative credentials on fiscal issues and gun-rights, and a background in engineering and business, having run a whiskey distillery in Kirby. But what really distinguishes him from his opponents is his willingness to speak out against some of Trump’s policies, and his priority on protecting public lands and keeping them in the public’s hands.
Mead, in other words, appears to be an old-school, pre-MAGA Western Republican. He reminds me a bit of Wyoming Gov. Mark Gordon, back before extreme polarization pulled him more and more rightward and into MAGA land. Wyoming’s primary is on Aug. 18.
Meanwhile, Utah just held its primaries, with some surprising results. Utah State Senate President Stuart Adams, a Republican, was defeated by challenger Stephanie Hollist. Adams was a strong supporter of the controversial proposed Stratos Project data center complex on the north shore of the Great Salt Lake. Also, incumbent Rep. Celeste Maloy trounced challenger Phil Lyman in the GOP primary for the 3rd Congressional District, with about 70% of the vote.
While Maloy was endorsed by Trump, and has plenty of extreme views, Lyman is the more MAGA of the two. And Trump pardoned Lyman after his conviction for leading an OHV rally down Recapture Canyon in the southeastern part of the state. Political consultant Taylor Morgan told the Utah News Dispatch that Lyman’s resounding defeat showed that his “very angry, very conspiracy-based, populist, toxic form of Republicanism (is) frankly wearing very thin, especially here in Utah.” Let’s hope he’s right!

I wrote Tuesday about how the Trump administration is eviscerating Biden-era oil and gas rules aimed at reducing methane emissions and ensuring companies clean up their own messes rather than foisting them onto the taxpayers. Now the changes are open for public comment.
Here are a few of the changes Trump and co. are proposing:
Bring back pre-Biden reclamation bond rates, which amount to just over $2,000 per well, which is insane, since the cost to reclaim and plug a single well easily can exceed $100,000. These numbers incentivized petroleum companies to walk away, forsake the bond, and abandon the well, leaving the tab for the taxpayers.
Reduce the current $10 minimum per-acre bid for leasing public land to $2, restore noncompetitive leasing, and slash royalties and filing fees for oil and gas companies.
Implement a new fee for protesting leases. And they plan to cut the 90-day public input period to just 10 days. In other words, they’re trying to cut out the public from decisions regarding public lands.
Gut the waste prevention rule (they wanted to roll it back altogether, but chose to revise it instead because it wasn’t clear which rule would replace it) by removing limits on royalty-free flaring and killing requirements that companies develop leak detection and repair plans.
Trump’s changes to the waste prevention rule will turn back the regulatory clock to the days when oil and gas operations on federal and tribal land vented and flared an average of 44.2 billion cubic feet annually of methane, which is usually accompanied by nasty volatile organic compounds and other dangerous compounds. That’s as bad for the climate as burning around 9 million tons of coal. But it also amounts to lighting money — your money — on fire and throwing it away. That vented methane is basically the same stuff you pay for to run your furnace, or to generate much of the electricity running through the grid. And since operators don’t pay royalties on gas they throw away, that cost American taxpayers some $166 million in lost revenue over a decade.
The result of all of this (and more) will be to rob taxpayers and sacrifice public lands and the climate to subsidize the same energy corporations that are raking in obscene profits thanks to Trump’s disastrous war on Iran. The administration argues that their proposed changes will save petroleum corporations operating on federal lands $17 million annually in compliance costs.
That sounds like a lot of money, until you realize that high oil prices have driven corporation’s profits to absurd highs. During the first quarter of 2026 alone, ExxonMobil raked in $8.8 billion in underlying, adjusted profits. Somehow, I don’t think several million in compliance costs is going to deter them from drilling.
🐟 Colorado River Chronicles 💧
Many of the West’s streams have entered their summer low-flow phase, a period that falls between the end of snowmelt and the beginning of the monsoon, while irrigation diversions are in full-swing. One of the most dramatic cases of this is, perhaps, the Colorado River itself as it flows through Grand Junction. This morning, the river was running at just 366 cubic feet per second near Palisade, which as reader Dave Grossman pointed out is low enough to allow someone to walk across the sprawling river bed.
Some other notably low flows:
Animas River in Farmington, NM: 104 cfs.
Dolores River at Bedrock, CO: .76 cfs (effectively dry)
White River near Watson, UT: 76.4 cfs
Green River above Flaming Gorge: 551 cfs
Green River below Flaming Gorge: 1,590 cfs
San Juan River near Caracas, CO (above Navajo Reservoir): 85 cfs
Colorado River near Hite, UT: 4,300 cfs
This has reduced daily average inflows into Lake Powell to about 4,800 cfs and dropping. It would be much lower than that, except that flows are being bolstered by upstream reservoir releases. Either way, inflows are far less than Glen Canyon Dam releases, which are averaging about 8,500 cfs daily (approx. 6,500 cfs at night and 10,600 cfs during the day). This disparity, exacerbated by reservoir evaporation, is lowering Lake Powell’s surface level, which currently sits at about 3,526.75 feet. Without substantial upstream rain, it will likely drop to 3,520 feet by early August.

Matt Jenkins wrote an excellent overview for the Water Education Foundation of the potential “Grand Bargain” on the Colorado River, which would require both the Upper and Lower basins to give up some of their Colorado River Compact claims not only to keep the system from collapsing, but also to avoid litigation.
The piece lays out the fact that the Compact is not only outdated, but also internally conflicted, in that it apportions the Upper Basin 7.5 million acre-feet of water per year, while also obligating it to allow the same amount of water to flow to the Lower Basin annually. That’s just not possible these days, given that there’s far less than 15 MAF in the river.
Southeastern Utah is known mostly as a mining hotspot for uranium, copper, with lithium emerging more recently. But it also hosts a potash extraction industry, and at least one company is looking to expand the potash footprint. Sage Potash says it has secured permits from Utah and San Juan County to begin drilling at is Sage Plain Potash project.
While this is only exploratory drilling, it’s notable in that it’s not occurring in the Lisbon Valley or near existing potash sites near Moab. Rather it is on the Great Sage Plain southeast of Monticello, in the archaeologically rich zone north of Hovenweep National Monument.

Yet another reason to worry about spewing more carbon dioxide into the atmosphere via fossil fuel burning: It can exacerbate acid mine drainage, the phenomenon that leads to toxic heavy metal loading in streams and other waterways. That’s the conclusion of a peer-reviewed study published in Communications Earth & Environment this April.
Acid mine drainage occurs when a mine excavation exposes once-buried sulfide-bearing rocks such as iron pyrite (FeS2) to oxygen and water. The hydrogen, sulfide, and oxygen come together to form sulfuric acid (H2SO4). Thus, the water becomes acidic, or its pH drops. The acidity dissolves heavy metals and the water picks them up. As the pH level of the water drops below 4.8, acidophilic bacteria begin feeding off the metals, releasing more acid into the solution and causing metal loading to occur up to 1 million times faster than in water with higher pH. Metal loading is bad for fish and other aquatic life.
The study found that elevated atmospheric carbon dioxide levels enhance the acidophilic bacterial activity, which accelerates iron and sulfur oxidation, acid formation, and metal loading. Zinc and cadmium, both of which are harmful to aquatic life, are more sensitive than other metals to rising carbon dioxide levels. Zinc loading is especially problematic in the Upper Animas watershed in southwestern Colorado.

Okay, I really don’t care that Anfield bought its first underground haul truck for its Velvet-Wood uranium mine in the Lisbon Valley of southeastern Utah. But I found this press release interesting for another tidbit: The haul truck was built by Young’s Machine Company, located in Monticello, Utah. I never knew Monticello had this sort of manufacturing industry. I gotta say, it’s kind of cool.

Water Quality in the Greater Yellowstone
A Guest Post by Robert Frodeman
Four million people visit Teton County, Wyoming, each year. They come to hike, float, and ski, snap pictures under the elk antler arches, and to partake in the myths of the American West. As the sign at the top of Teton Pass says, “Welcome Stranger. Yonder is Jackson Hole, the Last of the Old West.” Visitors expect to find a pristine environment. They don’t expect water quality problems reminiscent of a developing nation.
Teton County has some of the best drinking water in the country. Or most of Teton County does: Hoback, in the southern part of the County, has a nitrate problem. Nitrate is a health risk — most acutely to infants under six months, in whom nitrate is converted to nitrite by gut bacteria, interfering with oxygen transport in the blood and causing methemoglobinemia (blue baby syndrome). Many of the water systems in Hoback are on their last legs: two weeks ago, I had no running water and then a boil order at my home.
Jackson is the town, Jackson Hole is the valley that runs north of town in front of the Tetons. (‘Hole’ was what mountain men called a valley.) If you drill 20,000 feet into the valley floor you will hit the same sandstone layer that sits on top of the Tetons. This implies that the Tetons have risen some 25,000 feet over the last 10 million years.
Of course, mountains come down as they go up: the Tetons have been shedding sediment across all that time, piling up thousands of feet of gravel on the valley floor. Still more gravel was brought by the glaciers that flowed down from the Yellowstone Plateau. The Snake River meanders in front of the Tetons, but much of the river passes unseen below the surface, forming what is known as the Snake River Aquifer.
In effect, Jackson and Jackson Hole sit on top of a huge bathtub filled with gravel and water. This provides an abundant source of high-quality water for the town. But the bathtub only extends so far. The southern rim of the tub comes up at Munger Mountain five miles south of town. This is where the Yellowstone glacier stopped, and where the Snake River Canyon begins, which runs for 30 miles to Alpine and the Mormon communities of Star Valley.
Hoback lies four miles south of Munger Mountain — beyond the reach of the aquifer. Local residents must drill for their water. Local wells reach 200 feet down to the Bear River Formation. The water isn’t ideal – it’s brackish and can have a distinct sulfur smell (as do some of the local hot springs). The groundwater is also contaminated from horse farms and pig farms and (mainly) septic tanks and leach fields. Septic tanks can leak, and there is not enough biotic activity at this elevation and latitude for leach fields to function well. The result is nitrate levels in our drinking water which sometimes exceed EPA daily maximums.
Hoback is distinctive not only because of its geology. The billionaires live elsewhere in the County. There are two trailer parks nearby. Historically, local politicians have directed their attention to the Town of Jackson, Wilson, and the ski resort of Teton Village. But this has changed in recent years. Carlin Gerard of the Teton Conservation District formed a Hoback Stakeholders Group in 2019 to highlight drinking water problems. Covid disrupted that effort, but then a local non-profit called Protect Our Water Jackson Hole brought its energy and resources to southern Teton County.
In 2023 Hoback residents formed a water and sewer district. The district has now raised $7 million from the County and the State to build a municipal drinking water system. Water will be drawn from the Snake River just above the confluence with the Hoback. Construction should begin this fall and be done in a year or two depending on the weather.
At first it will only serve 125 residents: the district was made small out of fear of opposition. Teton County is solid blue, but past attempts had failed because of Hoback’s history of Red State, don’t-tread-on-me politics. In any case, it turned out that the demographic transition had already occurred: when the election was held the vote was 36-0 in favor. And there are now plans to annex a new affordable housing development that Teton County hopes will help address the local housing shortage.
Of course, the new system will only isolate residents from the nitrate problem. The environment will remain polluted, and people outside the district will still be on wells. The district has begun to price out a wastewater system, which is liable to be quite expensive. But you’d hope for nothing less for the Greater Yellowstone Ecosystem – and officials would hate to see an article in the New York Times about Teton County’s leaky septic systems.

June 29, 2026
The U.S. Supreme Court will weigh in on a legal battle over one of Colorado’s critical water sources as a neighboring state seeks to use more water from the South Platte River. The nation’s highest court on Monday announced it would hear the case, in which Nebraska officials claim Colorado water administrators are violating a century-old water compact by failing to send enough of the river’s water across the border. They also say Colorado officials are interfering in the neighboring state’s efforts to build a canal that would allow it to take more of the river’s water. Colorado Attorney General Phil Weiser on Monday denied Nebraska officials’ allegations that the Centennial State was violating the 1923 South Platte River Compact.
“Colorado is complying with the South Platte River Compact and not interfering with Nebraska’s efforts to build the Perkins County Canal,” Weiser said in a statement. “Today’s court decision merely opens the door for Nebraska to bring its claims against Colorado. Nebraska’s burden to prove those claims is incredibly high and we will vigorously defend Colorado’s full entitlements under the compact.”

Nebraska officials last year surprised Colorado leaders by taking their allegations to the Supreme Court. The two states had been meeting for months to discuss the proposed canal project. The Supreme Court asked the Office of the Solicitor General to weigh in on whether it should take the case. In May, the federal office — tasked with representing federal interests at the Supreme Court — argued that the court should decide Nebraska’s claim that Colorado is not sending enough water over the state border, but deny consideration of Nebraska’s other issues…Controversy over compact-obligated water deliveries between two states is a “quintessential” Supreme Court question, the brief states. The solicitor general’s office suggested appointing a special master — a subject-matter expert outside of the nine justices — to handle the issue. The solicitor general’s brief argues that the Supreme Court should not hear Nebraska’s arguments that Colorado is obstructing its efforts to build the Perkins County Canal because, the office said, Nebraska has not identified any actions by Colorado officials that have substantially interfered in the project. Other potential canal-related problems identified by Nebraska are hypothetical, the solicitor general said, as the state has just begun the permitting process and, therefore, is not ready for Supreme Court consideration. It’s unclear which issues the Supreme Court will consider as it hears the case. The order Monday allows Nebraska to file its complaint against Colorado.

The most significant water trial the San Luis Valley has ever seen opens this Monday morning in Courtroom A of the Alamosa County Judicial Center. At stake is the Fourth Amended Plan of Water Management for Subdistrict 1 of the Rio Grande Water Conservation District, which calls for a dramatic shift designed to match the amount of groundwater pumping to the amount of natural surface coming into the subdistrict.
Producers in Subdistrict 1 are under pressure to recover the unconfined aquifer of the Upper Rio Grande Basin, but so far the subdistrict has made little to no progress in creating a sustainable aquifer. The trial is scheduled for five weeks before Colorado Water Court Division 3 Judge Michael Gonzales.
The San Luis Valley’s highly-anticipated district water court case — the water trial of this century if you will — was originally scheduled to last five weeks beginning in January. It was pushed back six months to this summer due to the departure of a key witness in the fallout from a series of contentious October emails.
The Fourth Amended Plan of Water Management by Subdistrict 1 in the Rio Grande Water Conservation District has lived a precarious life without ever being implemented, going back to 2022 when it was originally crafted by subdistrict managers and January 2023 when it was adopted by Rio Grande Water Conservation District board.
Later came approval by the state engineer, and then after objections were filed against the new amended plan, Colorado Water Court Division 3 Judge Michael Gonzales set a trial date to commence on Jan. 5, 2026, and to last five weeks.
That is, until the week before Thanksgiving when Gonzales scrapped the January date in favor of June 29, 2026, some four years after the plan was first approved at the subdistrict level and the unconfined aquifer still in a historic decline. The judge did so after a series of emails sent by a key expert witness for the main objectors to the plan surfaced.
The effect is that a new plan to recover the Rio Grande’s unconfined aquifer, which has been approved at the local and state levels but still requires sign-off from district water court, remains in limbo.
Following filings by the Northeast Water Users Association and Sustainable Water Augmentation Group requesting a six-month continuance to the start of the trial, and the Rio Grande Water Conservation District and state Division of Water Resources objecting to the request, Gonzales ruled the two main objectors challenging the new aquifer recovery plan had good reason to ask for a six-month continuance after Taylor Adams, an environmental and water resources engineer for Hydros Consulting in Boulder, resigned from the case due to “personal and family circumstances.”
Adams was set to challenge the Subdistrict 1 water plan on a variety of engineering fronts until a series of emails he sent in October to State Engineer Jason Ullman and Senior Assistant Attorney General Preston Hartmann came to light. In one email, he tells Ullman, “Also, GFY.” In another, he emails that he is “no longer interested in anything other than publicly exploding the rampant corruption at DWR and the AG Office.”
And in an email sent Sunday, Oct. 19, to Attorney General Phil Weiser, Adams writes, “We haven’t met, but I understand that you’re running for governor of Colorado. You should know that if you continue this pursuit without addressing the persistent and laughable perjury that has been carried out in your name by Preston Hatman (sic) and Jason Ullman, you will be the subject of my attention throughout your campaign…”
The Rio Grande Water Conservation District asked Gonzales not to delay the water court proceedings due to the urgency to recover the unconfined aquifer and the lack of “credible evidence that demonstrates that Mr. Adams is unavailable. Rather, they now assert that he ‘should not be pressured into returning to the case at the risk of further harm to his mental health.’”
“In any event,” district water attorneys argued in their objection to a trial delay, “none of this changes the fact that the unconfined aquifer is still over 1.3 million acre-feet below the water levels measured in 1976, and more than 830,000 acre-feet below the water levels previously determined by this Court and the Colorado Supreme Court to be sustainable.”

Subdistrict 1 is home to the San Luis Valley’s richest crops of potatoes, barley and alfalfa. Without recovery of the shallow aquifer, the state is threatening mass shut down of groundwater pumping wells and requires both a master plan and annual replacement plans to show recovery efforts.
The subdistrict’s proposed Fourth Plan of Water Management is its most drastic effort yet to meet the state’s orders. The new plan, crafted in 2022 and adopted by the Rio Grande Water Conservation District in January 2023, is designed to “match the amount of groundwater pumping to the amount of water coming into the subdistrict.”
It does this through a 1-to-1 augmentation, meaning for every acre-foot of water used, an acre-foot has to be returned to the unconfined aquifer through recharging ponds. The amended plan relies on covering any groundwater withdrawals with natural surface water or the purchase of surface water credits.
Farmers in the subdistrict have expressed support for the plan, which includes a $500 per acre-foot overpumping fee that farmers would pay if they exceed the amount of natural surface water tied to the property in their farming operations.
Objections are coming from farmers who do not have natural surface water coming into their property and around the steep fee for purchasing surface water credits from a neighboring operation to offset groundwater pumping irrigation. Both proponents and opponents of the plan say the $500 per acre-foot overpumping fee could put farmers who rely on groundwater pumping out of business.
The five-week water trial will sort through these issues in much more granular detail. Any new strategy to recover the Valley’s ailing aquifer will shift into 2027 at the soonest.

June 25, 2026
In haggling with their down-river states about sharing the rapidly shrinking Colorado River, the headwater states have delivered a consistent message.
We don’t have two big reservoirs named Mead and Powell sitting upstream from us, they say. Mostly we must make do with what the sky delivers.
At the Upper Colorado River Commission meeting in Denver this week, the states reiterated this message, offering ample evidence from places like Emery, Utah, and Kemmerer, Wyo.
Lest anybody miss the message, Chuck Cullom, the director of the upper-basin commission, showed aerial images of farming areas in Colorado and the other upper-basin states. Far less green was evident in the Montrose area and on the Ute Mountain Ute Reservation during June than in 2024.
This exceptional year for drought and heat was described by several speakers in Denver as dire. “I want you all to recognize the significance and severity of the things we’re dealing with,” said the Utah representative, Gene Shawcroft. “Totally unprecedented.”
In western Colorado, a Meeker rancher used the same word to describe withered streams. “The situation here has gone from bad to dire.”
Upper-basin states have been in a tug-of-war for the last three years with lower-basin states about how to share this diminished river. As Becky Mitchell (above), Colorado’s representative, says repeatedly, we have a math problem. It’s impossible to continue releasing more water from reservoirs than flow into them. Upper-basin states, she says, “live within the means of the river.”

In crafting the Colorado River Compact in 1922, delegates assumed annual flows of roughly 17 to 18 million acre-feet annually at Lee Ferry, the legal division point separating the upper and lower basins. The 20th century delivered naturalized flows of 15.2 million on average.
In this century, flows have slackened even more. Since 2019 they have averaged 10.2 million acre-feet. This year less than 1 million acre-feet is expected to flow into Lake Powell other than releases from upstream reservoirs.
The compact pledged 7.5 million acre-feet to each of the two basins. The lower-basin states for many years over-used their allocation. Upper-basin states topped out at about 4.5 million acre-feet, using 3.5 million acre-feet in drier years.
Colorado and other basins states insist upon the right to use more water — if it’s there. Pre-compact rights of all Native American tribes have yet to be realized. All this creates a different math problem.
When the four upper basin states adopted their own compact in 1948, they wisely chose to use a percentage not an absolute number. That would make sense for the Colorado River Basin altogether — if the two basins could agree upon it. Tensions have elevated. Outwardly this marriage looks very rocky.
Might there be another way? Tanya Trujillo, New Mexico’s new representative, offered an intriguing statement at the Denver meeting.
“I think we need to think differently about some things,” she said. “In New Mexico, we’re going to be taking a fresh look at some of the issues that we are facing and really try to look for a collaborative process going forward.”
In time of crisis, she added, it’s important to “project calm, knowledgeable reassurance and try to be part of the solution, not part of the problem.”
For whom was that message intended? It was not clear. However, even in Colorado, some have suggested upper-basin states have overstated their case.
What cannot be contested is Mitchell’s assertion that demands cannot exceed supplies. This year, we’re robbing Peter to pay Paul. Water is being taken from Flaming Gorge and other federal upstream reservoirs to keep water in Powell. Blue Mesa Reservoir near Gunnison may have too little water to release any downstream, a condition called dead pool. The Bureau of Reclamation similarly sees that possibility for Navajo, the reservoir on the Colorado-New Mexico border.
The Bureau intends to release six million acre-feet from Powell for the lower-basin, leaving Powell 80% empty. The agency’s “most probable” projections see reservoir levels at Glen Canyon Dam early next year being too low to generate electricity.
In Grand Junction this week, people stood in the rain with sheer delight. It was a feel-good moment. But will El Niño save us from calamity? Maybe, but don’t bet on it. The warming climate seems to be rewriting the rules about how much water from the Pacific Ocean arrives on our mountains.
hat was the takeaway from a recent presentation by Brad Udall, a scientist scholar affiliated with Colorado State University. El Niños in the past have produced big water years. One was in 1983, the year that flood waters nearly broke Glen Canyon Dam. Often, though, an El Niño produces no more moisture than a La Niña.
“The real question” said Shawcroft, the Utah representative, “is what happens if next year looks like this?”

Some Colorado River experts are floating a concept to address the basin’s water woes that is both radical and mundane: permanently reducing the amount of water used by agriculture.
Many cities have already reduced their water use in recent decades while adding residents, proving that population growth doesn’t have to be tied to an increase in water use. A 2024 study by Colorado River scientists found that agriculture is responsible for about 74% of water used by people in the basin, meaning urban conservation alone cannot solve the crisis.
“I think we need to have permanent reductions in use on the table and agriculture will have to be part of that,” said Anne Castle, a Colorado River expert and a former federal representative to the Upper Colorado River Commission.
Castle was the lead author on a June 1 paper that urgently called on the entire basin to permanently decrease consumptive uses to avoid the worst impacts to reservoirs and water users. Castle and the paper’s other authors are Colorado River experts and academics, and are the brain trust of the basin sometimes referred to as the Traveling Wilburys, a joking reference to the rock music supergroup. But their message is anything but humorous.
The latest paper says another dry winter would deplete remaining storage and result in devastating consequences like run-of-the-river operations where the nation’s two largest reservoirs can only release downstream the same amount of water that flows into them. It’s the last stop before deadpool, when levels are too low to release water. The authors urge water managers to act immediately to reduce use and avoid a system crash.
But permanently cutting the amount of water that goes to agriculture remains a controversial topic, and water managers from both the Upper and Lower basins say drying up land is not a solution for their basin. Most conservation programs up until now either have been temporary or have allowed the saved water to be used elsewhere. Castle said the problem is especially difficult when people’s livelihoods are on the line.
“The folks who are vulnerable to those kinds of permanent reductions are understandably resistant,” Castle said. “But there’s not enough water. The river won’t allow us to use the same amount of water that we’ve been accustomed to using in the past.”
The seven states that share the Colorado River are under increasing pressure to cut water use as one of the worst droughts on record threatens the water supply for millions of people. On the heels of one of the hottest and driest winters since measuring began, spring flows into Lake Powell this year are projected to be the lowest on record.
Much of the $4 billion from the Inflation Reduction Act earmarked for drought mitigation has gone toward short-term conservation. Water users in the Lower Basin states (California, Arizona and Nevada) were paid to temporarily leave water in Lake Mead. And in the Upper Basin (Colorado, New Mexico, Utah and Wyoming), the feds paid irrigators $45 million to leave fields dry during a two-year reboot of a pilot conservation program.
But in the midst of a climate change-fueled megadrought that has already robbed the river of at least 20% of its flows, experts say temporary measures no longer cut it. Water managers are reckoning with the reality that the river will probably never again deliver what was promised a century ago by the Colorado River Compact. The demand for water now far outstrips the dwindling supply.
“Are we going to continue to spend hundreds of millions of dollars a year and not have a permanent solution?” said author and Colorado River expert Eric Kuhn. “I think, at some point, it just makes economic sense to go ahead and say, ‘Let’s buy out the existing demand.’” [ed. emphasis mine]

Buying out demand
Against this backdrop, some in the academic community are advocating for the federal government to either set up a voluntary program to buy and retire lands that use a lot of water or pay landowners who agree to permanent restrictions on water use.
A paper released last year and authored by Kathryn Sorensen and Sarah Porter, who are Colorado River experts at the Kyl Center for Water Policy at Arizona State, lays out how this could be done. Eligible land would have to meet certain characteristics, including being in an area where the economic impacts of not using water are least painful and where impacted crops could be feasibly grown outside of the Colorado River basin, among others.
According to Porter, the federal government should be the entity that buys down demand. The large infrastructure projects funded by the feds in the 20th century are what created booming irrigated agriculture in the West to begin with. And the other entities in the basin that have the ability to buy agricultural water want to use it themselves, not keep it in the system.
“A reset in the Colorado River basin really is needed,” Porter said. “We have a lot of agriculture that’s really a legacy of how the United States was settled… . And now we’re grappling with overallocation and shortage and struggling to figure out a way to manage the Colorado River.”
The proposal is different from the much-derided “buy-and-dry” which usually involves an opportunistic transferring of water from agriculture to cities, not an overall reduction in water use. Still, the potential negative impacts to rural communities have to be considered.
“You have to have a provision for what happens to the land when you remove agriculture and what happens to the local economy when you remove agriculture,” Porter said.
And experts say there is a precedent for the type of federal buyouts that could help the drought-stricken river: the Bankhead-Jones Tenant Farm Act from 1937. This New Deal piece of legislation was a response to the Dust Bowl and allowed the federal government to buy and retire badly eroded or economically unproductive farmland.
The paper says a Colorado River program could start not with those that grow valuable vegetables in winter but, rather, with lands that use a lot of water but have low economic output. The paper says retired agricultural lands could be used for alternative purposes that support local economies such as recreational opportunities or low water-use industries.
Figuring out how to implement conservation programs without harming rural agricultural communities has been a main focus in recent years of the Colorado River Water Conservation District, which works to keep water on the Western Slope. River District General Manager Andy Mueller said that agriculture has a role to play in reducing water consumption, but that permanently retiring agricultural land is a misguided approach that will put the country in danger of not being able to feed itself. Programs should remain temporary, and focus on efficiency improvements and growing less-thirsty crops, he said.
“If it’s temporary, if it’s well-designed in a way that respects local communities, traditions and practices, is custom-built for each community in a way that really tries to do as little economic damage as possible — potentially even bringing some benefits to those farming families that participate — there are ways to do it,” Mueller said.

On the fringe
Although certain academics and experts are talking about permanently drying up agricultural lands as a means of saving water, the concept remains on the fringe of Colorado River politics. It’s both the third rail and the elephant in the room.
“It’s going to pull away from the fringe really quickly when you’ve got to really justify continuing to pay on an annual basis forever,” Kuhn said. “We’re just trying to get the discussion out there, make it acceptable to have the discussion.”
On top of the abysmal hydrologic conditions, the basin is also in the midst of a management crisis. After two years of negotiating, the Upper Basin and Lower Basin states have failed to reach a consensus on how they will share future cuts and have blown past deadlines to come up with a plan. The responsibility for river management now falls to the federal government, which is scheduled to release this summer a short-term operating plan for Lake Powell and Lake Mead.
Part of what makes the problem so tricky is that water managers are still guided by the Colorado River Compact, a century-old agreement that splits the river’s flows evenly between the two basins. Upper Basin water managers still cling to the notion that because their states are already living within the 7.5 million acre-feet of water allotted to them annually, cutbacks are the responsibility of the Lower Basin, which they say uses more than its fair share.
Becky Mitchell, Colorado’s lead negotiator in talks among the seven states, said that permanent dry-up of agriculture in the Upper Basin isn’t necessary because the Upper Basin states already send more than 8 million acre-feet — more than legally required — of water downstream per year. Dry-up may be part of the overall solution, she said, but each state should take its own individual approach to making cuts.
“Those durable reductions are going to be required (for the Lower Basin) to first get in line with their apportionment, but then getting in line with the available supplies is a whole ’nother conversation,” Mitchell said.
California’s representative, JB Hamby, said permanent fallowing doesn’t have a place in reducing the state’s demand either. California is home to the biggest urban and agricultural water districts, as well as the largest allocation of Colorado River water of any of the seven states that share the river.
“In the case of California, there’s no real discussion or interest whatsoever in the retirement of ag lands,” Hamby said. “Land in Southern California that receives Colorado River water is so extremely productive. There is a year-round growing season where every single day of the year there are things being grown.”
Past water savings in Southern California have mostly come from efficiency improvements on farms and in delivery systems, and from deficit irrigation programs in which water is temporarily taken off fields for part of a season. In the absence of a seven-state deal, the Lower Basin states have offered up 700,000 acre-feet of cuts per year through 2028, which is on top of an initial 1.5 million acre-feet in cuts. Most estimates say the basin needs to cut water use by 2 million to 4 million acre-feet.
“There’s full agreement that water should be reduced,” he said. “There’s not agreement in how or where it should be reduced. So the Lower Basin is moving forward, doing our thing, making reductions.”

Ultimately, discussions about permanently reducing the amount of water that goes to farmlands in the basin remain difficult, in part because agricultural water rights are some of the biggest, oldest and most politically powerful in the basin. But there is also an attachment to the American West’s farming and ranching heritage.
“We love agriculture; it’s part of our roots,” Porter said. “We don’t like to think about losing agricultural production. I think we are generally hesitant to have that conversation, and we really haven’t had it as a basin.”

Western Water In-depth: A ‘wild idea’ to defuse the colorado river compact’s legal time bomb has been kept alive by seasoned observers who believe it could still save the river
For the past 20 years, the Colorado River has been operated under a set of guidelines negotiated between the seven states that depend on the river. Those guidelines expire this year, and after five years of grinding negotiations over a new agreement, the upstream states of Colorado, Wyoming, Utah and New Mexico remain deadlocked against the downstream states of California, Arizona and Nevada.
Some 40 million people and 5.5 million acres of farmland depend on the river’s water. But after the states failed to meet two federal deadlines in three months, the river is in a moment of unprecedented crisis. A dire snowpack has left flows just 15 percent of normal, many farms without water and several cities scrambling to secure water supplies as they gird themselves for shortages.
That has set up a showdown over a legal time bomb that’s been ticking away at the heart of the Colorado River Compact since the river’s guiding document was signed more than 100 years ago. The Lower Basin states believe the Compact promised them a minimum delivery of water sent down the river from the Upper Basin. The Upper Basin states believe the Compact promised them a fixed amount of water that they could rely on to meet future growth. As the river’s flows have dwindled, those two supposed guarantees are proving to be irreconcilable.
Experts have seen the showdown coming for a long time, but climate change has accelerated the day of reckoning. In 2000, a drought sunk its teeth into the river and hasn’t let up. Dubbed the Millennium Drought, it is now recognized as one of the worst droughts on the river in more than 1,200 years — and may actually be the beginning of a long-term shift to a drier reality.
Despite near-endless negotiations to find a way to keep the river’s massive reservoir system from crashing — an effort that began over two decades ago — the drought may have finally pushed the Colorado River Compact to its limit. Now, the system is nearly empty and runoff from this winter’s snowpack, the source of any water that might offer even a small hope of relief, will be among the lowest since Glen Canyon Dam was built near the Arizona-Utah border, creating Lake Powell, more than 60 years ago. Flows in the river are perilously close to hitting the primary legal “tripwire” in the Compact. Once that’s crossed, the Lower Basin states would likely try to force the Upper Basin to deliver their water apportionment downstream — a prospect long considered unthinkable.
“All those negotiations helped push the day of reckoning back further, and helped delay the inevitable,” says Doug Kenney, who heads the University of Colorado’s Western Water Policy Program. “But at some point, you just have to acknowledge the fact that the numbers don’t add up and you’re going to have to deal with it. We’re at that point.”
Two obvious paths now lie ahead. One is a courtroom fight, either against the U.S. Secretary of the Interior or a challenge between two states under the terms of the Colorado River Compact, which would go directly before the Supreme Court. A high court case would be a doomsday scenario, a messy and protracted legal battle that, until now, the seven states desperately sought to avoid. The other potential path is a stopgap fix, a short-term interim plan negotiated between the states or imposed by the Interior secretary. That could, at least temporarily, forestall a trip to court, but it wouldn’t resolve the fundamental conflict.
For more than two decades, however, the possibility of a third path has stubbornly persisted in the background: A “grand bargain,” an idea first proposed in 2005 by Colorado’s negotiating team early in the effort to grapple with the worsening drought. The concept was an unorthodox bid to defuse the ticking time bomb — but it would require each basin to trade away its most cherished claim on the river.
‘A WILD IDEA’
Roughly 90 percent of the Colorado River’s flow originates as snowpack in the Rocky Mountains. One of the principal goals of the 1922 Compact, which is essentially a seven-state treaty, was to avoid future legal battles by creating an “equitable division and apportionment” of water between the Upper Basin states in the river’s headwaters and the faster-growing Lower Basin. The Compact apportioned 7.5 million acre-feet a year from the mainstem of the river to each basin. (An acre-foot is 325,851 gallons, enough to supply the average annual needs of roughly 3 households, depending on their location and climate.)
The Colorado River Basin spans seven U.S. states and is divided into Upper and Lower Basins. Lake Powell, upstream from the Grand Canyon, and Lake Mead, near Las Vegas, are the two principal reservoirs in the Colorado River water-supply system. (Bureau of Reclamation)
The Compact also contains a requirement that the headwaters states not deplete the flow of the river below 75 million acre-feet, plus another roughly 7.5 million acre-feet (half of the apportionment earmarked for Mexico), on a 10-year running average. Those provisions were intended to provide surety to the downstream Lower Basin states that they would receive their 7.5 million-acre-foot annual apportionment and that the basins would share equally in the Mexican obligation. If the 10-year running average requirement is violated, the Lower Basin states could — at least in theory — initiate a Compact “call” against the Upper Basin in an attempt to force the headwaters states to deliver more water downstream.
For roughly 80 years after the Compact was signed, the prospect of a Compact call was purely theoretical. Then the Millennium Drought set in. By 2005, the two flagship reservoirs on the Colorado River — Lakes Mead and Powell — were half empty.
The drought was pushing the river’s flows closer to a Compact violation trigger, making the risk of a call by the Lower Basin a growing probability. The Lower Basin, particularly Arizona, was insisting on guaranteed releases of water from Lake Powell. And because Colorado has the biggest share of the river within the Upper Basin and uses a greater portion of its apportionment than the other upstream states, it is most at risk. It began searching for a way to slip out of the legal noose of a Compact call.
In September 2005, the seven states’ top negotiators met in Albuquerque, New Mexico. During a lunch break, Colorado’s team made its pitch. The state’s negotiators proposed that the Lower Basin waive its right to force a downstream delivery through a Compact call. In exchange, the Upper Basin states would limit their water use to less than what’s strictly apportioned in the Compact, thereby reducing potential demand in the headwaters of Colorado and Wyoming that supply nearly the entirety of the river’s flow.
The offer was essentially a simplification and reframing of a dizzying array of technical disagreements over various provisions of the Compact — an attempt to throw spaghetti at the wall to see if it would stick.
Jim Lochhead, who had previously been Colorado’s top negotiator and in 2005 was serving as a legal advisor on the state’s team.
“My recollection was that it was a pretty spontaneous proposal,” says Jim Lochhead, who had previously been Colorado’s top negotiator and in 2005 was continuing to serve as a legal advisor on the state’s team. “We weren’t making any progress, and it was pitched as, ‘If you really want to cut through all of this and get to the bottom, here’s a wild idea.’”
The proposal sparked discussion among all the parties at the negotiating table but also raised difficult issues.
“It was a great concept on paper,” says Pat Mulroy, who was the head of the Southern Nevada Water Authority and Nevada’s principal negotiator at the time. “Whether it was politically doable or not is a whole other ball game.”
In large part, that’s because a grand bargain would have forced both basins to give up assurances in the Compact that they consider sacrosanct.
“I’m not sure the Upper Basin would ever have agreed to limiting their ability to fully develop their 7.5. It’s like giving up your birthright — I’m not sure they could have sold that at home,” says Mulroy. Conversely, she says, “giving up that call provision is really the only weapon the Lower Basin has.”
And, indeed, following its spontaneous birth in Albuquerque, the proposal ran into stiff political headwinds back home in Colorado, where it failed to get then-governor Bill Owens’ blessing.
“I wasn’t directly representing the state of Colorado at that time; I was representing Colorado water users,” Lochhead says. “And when I brought the idea back to the state, it pretty quickly got shot down: ‘No, we can’t agree to anything that would not keep the dream alive of 7.5 million acre-feet being developed in the Upper Basin.’”
The prospect of a grand bargain itself faded from discussion. And yet, in ways that aren’t often acknowledged, it continued to shape the broad contours of the negotiations that unfolded over the next two decades.
The quest to escape the noose of a Compact call has remained central to Colorado’s bargaining position.
“The concept of a waiver of a Compact call is alive and well,” says Anne Castle, a former assistant Interior secretary who is now a senior fellow at the University of Colorado. “The quid pro quo for that waiver has taken different forms.”
To a large extent, the details of the various offers the Lower Basin has made in exchange for a possible waiver — which have sometimes been characterized within the negotiations as “mini grand bargains” — have never become public. What is clear is that the two basins have consistently failed to cut a deal.
Instead, the seven states adopted a more incremental approach, negotiating a series of drought-protection agreements based on smaller, more politically palatable deals. While that’s been a safer path for everyone politically, it has brought other kinds of risk.
“It just added layer upon layer of Gorilla Glue and Band-Aids that’s made it much more complicated to try to unwind or develop new agreements,” Lochhead says, “and has obviously proven to be inadequate in protecting the system.”
A SECOND LIFE
While the concept of a grand bargain led a short life at the negotiating table, it has gone on to live a remarkable second life. The idea was picked up and revived by a loose-knit group of seasoned observers of Colorado River issues who, for years, have called for more durable alternatives to the patchwork of ideas [ed. “The Law of the River”] in play among negotiators.
Eric Kuhn was a member of Colorado’s negotiating team when the grand bargain was proposed in 2005. At the time, he was the general manager of the Colorado River Water Conservation District based in Glenwood Springs and he has written thoughtfully and voluminously about the river’s problems. After his retirement in 2018, he partnered with John Fleck, a former journalist who is now author-in-residence at the University of New Mexico’s Utton Center, to write Science Be Dammed: How Ignoring Inconvenient Science Drained the Colorado River.
Kuhn and Fleck concluded the book by observing that “there is not enough water in the Colorado River for all the lawyers to be right,” and suggested the grand bargain as a way to avoid the courtroom.
“The basic idea of a grand bargain is, in lieu of litigation, we’re going to agree to something that both sides want,” says Kuhn.
He and Fleck weren’t the only ones who pushed for more serious consideration of the idea. Doug Kenney at the University of Colorado also has championed the concept. In 2012, he enlisted Kevin Wheeler, a widely respected engineer and fellow at Oxford University, to undertake modeling analysis of the kinds of trade-offs a grand bargain might require.

In 2021, Wheeler — together with a group of collaborators including Kuhn, climate scientist Brad Udall and Jack Schmidt, the director of Utah State’s Center for Colorado River Studies — published a white paper called “Alternative Management Paradigms for the Future of the Colorado and Green Rivers.” It was a comprehensive assessment of more ambitious strategies for weathering the drought and climate change than had emerged from now-perpetual negotiations between the states.
“New approaches that are responsive to significantly drier climate conditions and changing patterns of consumptive uses may require bolder policy initiatives that exceed the incremental approach of modern management,” the group wrote. “It is critical to explore alternative water management strategies that may extend beyond the framework of the Law of the River as presently interpreted.”
The following year, the team published a paper in the journal Science titled “What Will it Take to Stabilize the Colorado River?” And, it turned out, stabilizing the system would take something that looked a lot like a grand bargain.
Assuming the drought persists as it has since 2000, Wheeler and his partners identified two scenarios that would stabilize the river, both of which assumed the Lower Basin had waived its ability to make a Compact call. In one, the Lower Basin would need to decrease its water use by about 2 million acre-feet a year when Lake Mead and Lake Powell reach low levels. That would assure it of about 78 percent of its apportionment — an amount roughly in line with cuts it has already committed to taking. In exchange, the Upper Basin would have to cap its water use at 4 million acre-feet. But that’s only slightly more than half of its 7.5 million-acre-foot Compact apportionment, and roughly 300,000 acre-feet less than what it currently uses.
The second scenario — call it the “near-parity scenario” for simplicity — more equally distributed the Upper and Lower Basins’ relative cuts in apportionment. In it, the Upper Basin would cap its use at 4.5 million acre-feet, leaving it with 60 percent of its Compact apportionment. The Lower Basin would be able to use about 67 percent of its Compact apportionment when reservoirs are low, just slightly more percentage-wise than the Upper Basin. But it would have to cut its uses by 3 million acre-feet below its apportionment.
That would stabilize the system — or at least go a long way toward doing so — while largely meeting existing water demands in both basins. The Upper Basin currently uses about 4.3 million acre-feet per year. The Lower Basin, after ramping up an aggressive water conservation effort since 2007, has driven its annual use down to about 6 million acre-feet per year, and has signaled that it could likely reduce demand further.
But it would leave practically no leeway for future growth, at least without reshaping the socioeconomic landscape across the entire Basin. In particular, any future urban growth could come only by shifting significant amounts of water from farms to cities.
HARD MATH
Today, there is a simple, hard reality on the Colorado River: The available water supply is already maxed out. Water use throughout the basin needs to be reduced by roughly 25 percent just to make the numbers work now — to say nothing of the future, which is likely to be significantly drier.
In Colorado, that has raised hard questions about fairness, the “equitable division and apportionment” provision of the Compact, and the assurance the state thought it had that its water would be there to develop when it’s finally ready.
“Everyone agrees that there should be an equitable division of water, and the word ‘equity’ is one that everyone will rally around,” says Kenney. “But does equitable mean equal? That’s the crux of the issue.”
Over the past several years, Colorado’s attorney general, Phil Weiser, has been building his office’s staff of water lawyers. This January, Weiser, who is currently running for governor, appeared before a joint hearing of the state legislature’s judiciary committees.
“If we can’t get a deal — and I’m committed to not getting a bad deal just to get a deal — we’ll be in litigation. We’re ready for it,” he said. “If and when we can get a reasonable deal based in reality, I’m for it. But if we can’t, then we will be falling back on our rights under (the) 1922 Compact.”
Because of the peculiarities of the water-rights hierarchy in the Lower Basin, Arizona is arguably most at risk there. In March, that state — whose governor, Katie Hobbs, is running for re-election — retained the high-powered law firm Sullivan & Cromwell to represent it in potential Colorado River litigation. At the time, a spokesman for the governor said, “it’s critical that Arizona be prepared to defend ourselves in court if an agreement cannot be reached or the Law of the River is violated.”

“It is very difficult for a political figure — and they’re all political figures, even if they’re not elected — to agree to reduce the water use of their constituents and keep their career alive,” says Anne Castle. “They have to be able to tell their constituents, ‘I’m fighting for your water. I’m doing everything I can to keep your water secure, and it’s the other guy’s fault.’ The political incentives are directly at odds with the kind of compromise that’s needed in this type of hydrologic situation.”
Following the breakdown in negotiations between the Colorado River states, the federal government has announced its intention to step in. In May, the Bureau of Reclamation, on behalf of the Department of the Interior, revealed that it is preparing the first of what could be a series of five two-year interim plans for the river.
The final details are expected to be released this summer. But the federal government has indicated that the Interior secretary could cut water deliveries to the Lower Basin states by up to 3 million acre-feet — 40 percent of their Compact apportionment. During a briefing for Arizona water users in May, Brenda Burman, the head of the Central Arizona Project, presented modeling analysis of the proposed reductions and noted that, given the diminished releases from Lake Powell, the Upper Basin is “in a definite breach of the Compact by Sept. 30 of 2026.”
Owing to some quirks of river history, the secretary debatably has less authority in the Upper Basin, and so Reclamation has proposed no cuts there. But as climate change continues to eat away at snowpack and river flows, the Upper Basin states will likely be forced to cut back their uses anyway. Regardless of what the Compact says the Upper Basin gets, the water simply won’t be there.
And so now the seven states are facing a situation eerily similar to those in the near-parity scenario Wheeler and his colleagues laid out in their Science paper four years ago — but without a bargain.
COMING FULL CIRCLE?
In many ways, the prospects have never been worse for something like a grand bargain. Yet the fundamental problems the grand bargain was intended to solve have only grown sharper in the 20 years since it was first proposed.
“The grand bargain has gotten a bad name,” Kuhn says. “But if these issues aren’t resolved through a grand bargain, they’re going to be resolved through litigation.” In 2007, he says, the river’s reservoirs still had ample water to work with. “With empty reservoirs, you cannot finesse these issues.”

Litigation could come as soon as August, when Reclamation will likely release a record of decision for its proposed new operating plan. Legal action could take one of several paths. The one with the highest stakes would be direct enforcement of the Compact, likely in the form of a Compact call brought by Arizona and the other Lower Basin states against the Upper Basin states. Because the Compact is essentially a treaty between multiple states, that would go directly before the Supreme Court. But such cases are often grindingly long: Arizona’s 1952 lawsuit against California over Colorado River rights took a dozen years to resolve. A case in the Supreme Court could put the river in protracted litigation during a time of profound crisis.
Other, more limited challenges are possible, most likely against the Bureau of Reclamation or the secretary of the Interior for failure to comply with the Compact or violating environmental laws. But they, too, are not without risk.
“I have a hard time believing you could keep litigation contained, once that genie’s out of the bottle,” says Kenney. “I just have to believe that inevitably blows up into a full-fledged interstate litigation and it bumping right up to the Supreme Court.”
As the odds rise of a legal challenge to the Compact that could ultimately wind up before the highest court in the land, the fundamental tension the grand bargain was intended to resolve will likely be front and center before the justices. And, paradoxically, that could force the states themselves to finally make the really tough sacrifices they’ve been trying to avoid.
“I think that a road to a grand bargain runs through litigation,” says Kuhn.
That’s because in past interstate fights over shared rivers, the Supreme Court has typically appointed a water-law expert known as a special master to referee such cases. The most recent example is the dispute between Texas, New Mexico and Colorado over the Rio Grande. In that case, Kuhn notes, “the special master said, ‘You don’t want me or the court to decide this; get in a room and negotiate it.’ The special master kept the pressure on the states to negotiate.”
This May, the Supreme Court approved a settlement between those three states. Still, even that resolution only came a full 13 years after the case was initially filed, and it involves relatively small reductions in overall water use.
On the Colorado River, both water and time are in far shorter supply.

Last post here, I suggested that at least some of the ongoing failure of the seven Colorado River states to reach agreement on a river management plan for even the next several years, let alone new century, stems from some ‘elephants in the river.’ You know – the big things that nobody wants to look at because they are so big. So big that some of the rules and guidelines we operate under were created to avoid having to address them.
The first ‘elephant in the river’ I discussed last time was the single-minded focus on the Colorado’s surface waters, and a failure to begin considering the whole integrated water supply, surface water and groundwater – of which the surface water is a relatively minor part, with users going to the groundwater in a haphazard way when the surface water is insufficient.
I did make an incorrect statement in that analysis, however. I said that Colorado was the first, and thus far only, state to begin integrating groundwater into its appropriation priority system statewide. (Arizona developed – by federal mandate – a Groundwater Management Plan circa 1970 for those specific parts of the state served by the Central Arizona Project.)
This is true about Colorado – but I was mistaken in implying that the all groundwater use was integrated into its appropriation system by 1969 legislation. Only alluvial groundwater is covered by that law – groundwater that is naturally integrated with surface water, either trickling into the surface streams when the groundwater table is high or drawing riparian water from the surface streams when the water table is low.
Not covered by the Colorado law are ‘non-tributary’ aquifers that have no natural interaction with the surface waters – aquifers like the Oglalla Aquifer in eastern Colorado, or the Denver Basin aquifer. Most of their water filters down from the alluvial groundwater, and only modern pumping technology makes that groundwater accessible to surface use. Most of these deep aquifers have accumulated their water slowly over geological periods of time, and even moderate use of their water dips quickly into ‘water-mining.’ Colorado law for such aquifers attempts to limit annual use to a hundredth of a presumed 100-year supply, but no one knows for sure how much water is really down there, or whether it will truly constitute a 100-year supply.
The standard response throughout much of the basin to shortages in surface water is to go to groundwater pumping; if ‘tributary’ (alluvial) groundwater is tapped, the pumping will gradually lower the water table – which in turn will begin to diminish the surface streams, which in turn will increase the pumping – et cetera, a vicious downward cycle. And the pumping of ‘non-tributary’ aquifers is largely unregulated in the basin.
At any rate – apologies for the error, and thanks to John McClow for pointing it out.
And on to another elephant in the room. Is it finally time to determine limits on the presumed universal applicability of the appropriation doctrine? To avoid being shot before I finish the paragraph, I will say immediately I am not suggesting doing away with the appropriation doctrine; it is a good enough last resort down on the ground where the appropriation doctrine started, for working out local problems of water use on a surface stream when neighborliness fails – that is, when old grumps and feuds preclude the ‘gentlemen’s agreement’ on sharing out what water is available, rather than shutting down the junior users with a ‘call’ so the seniors can get all their decreed water. After two or three generations, seniority can be acknowledged, but is too abstract to apply against your neighbors, if a plan for sharing blameless misfortune can be worked out.
The abstraction, however, becomes more applicable when it is distant water organizations calling out other water organizations upstream, or an earlier developed watershed placing a call on users in an adjacent more recently developed watershed. And when a stream is declared by the district engineer to be over-appropriated – not enough water to fill everyone’s decrees in a near-average year – it becomes even more abstract, a tool for enforcing a status quo, and nothing anywhere about what represents the best uses of the water.
There are, in other words, some areas in which the appropriation doctrine gets stretched beyond its elastic limits by emerging challenges of water use; any questions about ‘best and highest use’ have been essentially declared unanswerable as a matter of conflicting values, and it just seems easier to let seniority of use be the ultimate determinant of priorities.
A century ago, with California quintupling its population in the first two decades of the 20th century, the other six of the seven states in the Colorado River Basin (Arizona, Nevada, Colorado, New Mexico, Utah and Wyoming) began to worry that California might put so much of the river’s water to use that there would not be enough unappropriated water for them to put to use when their time of growth came. They were all committed to versions of the appropriation doctrine within their states, but came to believe that reliance on the appropriation doctrine alone at the interstate level could cause more regional problems than it would resolve.
That concern was affirmed in 1922 when the U.S. Supreme Court resolved a conflict between Colorado and Wyoming over a Laramie River tributary that started in Colorado but was put to use first in Wyoming; the court declared that states who used the appropriation doctrine intrastate would also have to respect each other’s appropriations interstate. This made real the specter of slow-growing upstream states having to let all their Colorado River water go downstream to fill huge Arizona and California decrees.
So they assembled in 1922 to try to do something about that – a fundamental fact about the Colorado River Compact commission that we tend to forget: the original intent of the compact commissioners in 1922 was to develop an alternative to the appropriations doctrine at the interstate level. They came together with the intent of working out a seven-way division of the use of the river, based on possible future development, that would eliminate a horse-race of interstate appropriative competition. Six of the states convened the commission because they feared California, and California reluctantly participated because it knew the feds would never build the big control and storage dam they needed until all seven states were on board with it. That seven-way division trumping interstate appropriation was what the Compact Commissioners assembled to do –and spent a frustrating week early in 1922 trying to do.
They were unable to effect a seven-way split for a couple of reasons: for one thing they had no good measure of how much dependable water was in the river; estimates at the time ranged from 12 to 20 million acre-feet (maf). But for a second thing, the sum total of the water they each felt their state needed, based on rosy early-20th-century estimates, was closer to 24 maf – and nobody wanted to go home having backed down from their carefully imagined numbers.

What they did instead – in order to persuade Congress that there was general agreement – was to cobble together the Compact we are burdened with today; they created what Commission Chair Herbert Hoover called a ‘temporary equitable division’ of the seven states into Upper and Lower River Basins, until ‘ those men who may come after us, possessed of a far greater fund of information’ could do the ‘further division’ of the river among the states.
They also decided – as early 20th-century Americans would – to lean toward the more optimistic estimates of river flow, dividing ‘equally’ between the Basins only 15 maf of a river they presumed would continue running 16-20 maf – hence the 7.5 maf for each Basin written into the compact, to be further divided among the states of each Basin in their own good time. That left some water for Mexico, but they did nothing specific for the Indian tribes in the basins because national Indian policy at that time was ‘soft genocide’ – full assimilation (‘kill the Indian, save the man’), leaving tribal water a concern they thought would disappear.
This all made reasonable sense with a river running a quarter-century average of just under 18 maf – but then through the 1930s the river experienced a drought unsurpassed until the past quarter century. By the end of World War II, Colorado river water users had a ‘far greater fund of information’ about the river’s flow, which would have made it a good time to have ‘fixed’ the Compact – but the growing fund of information was all bad news that no one wanted to incorporate into a more realistic policy. So by default the ‘temporary equitable division,’ with its mythic 18 maf river, took on the permanence of something carried off a sacred mountain carved in stone.
And now – we are seeing it reduced to a sad irony. The states of the Lower Basin had their fears too, and wanted a clause in the Compact stating that, should the Upper Basin states have a wild spurt of growth, they should not ‘deplete the flow’ to the Lower Basin below an average of 7.5 maf a year. But now – when it looks like diminished flows throughout the basin might really drop the flow at the division point between basins below that average – the Lower Basin is threatening the Upper Basin with an Article III(d) ‘call,’ saying the upper states will have to cut their own uses enough to meet the lower states’ fantasy 7.5 maf. States that set out a century ago to create a compact that would transcend the appropriation doctrine at the interstate level are now trying to turn that ‘temporary equitable division’ into what amounts to a senior interstate water right.
There has to be a level, or category, of action in which the law of first-come first-served is transcended by other considerations. And can we not say, at this point a century later, that the original intention of the compact commission has been achieved de facto? No state will ever get the use of more water than it had (or believed it had) around the turn of the century because there is even less water now. For better or worse, the use of the river has been distributed among the states (including some of the tribes) and Mexico.

Whether this is an equitable division is arguable; the states of the Lower Basin have been using roughly two-thirds of the river’s water, the Upper Basin states around one third, rather than the 50-50 split explicit in the Compact (7.5 maf per Basin). But arguably that does reflect the relative productivity of Lower Basin agricultural use (by far the largest use) and also its millions of urbanites drawing on it for at least part of their municipal water. It was a huge step toward reality when the Lower Basin states finally agreed that they must absorb the Lower Basin’s system losses (mostly evapotranspiration) and their half of Mexico’s allotment out of their own shares of the river, rather than relying on a fictional surplus to cover it – a fiction that combined with drought to draw down both Powell and Mead Reservoirs to the dangerous level where they linger today.

The 1948 Upper Colorado River Compact was the first reality-based document in the ‘Law of River’ portfolio because its negotiators knew by then – that ‘greater fund of knowledge’ – that it was doubtful that there would always be 7.5 maf for their use, and actually accepted that as their reality. So the divided their ‘half’ of the river into percentages for each state of whatever was left for the upper states after the Lower Basin got it Boulder Canyon Project Act waters. After three-quarters of a century, the four states are not too far from those percentages in their development of around 4.5 maf; only Wyoming is significantly under its 13 percent; Utah is a little below its 23 percent; and Colorado is a little over its 51.75 percent. Given the geographic irrelevance of western state boundaries (the Little Snake River crosses the Colorado-Wyoming border half a dozen times), this was pretty good 1948 estimating.
The reality today is that all Colorado River water users in all seven basin states are using a finite and measurable resource that will probably continue to diminish for the foreseeable future as we continue to heat up the planet, and we need to come to an agreement on what that means for all users. [ed. emphasis mine]
It seems to me there are three ways to address that diminishing flow. One way is to continue to accept the divine sanctity of the Colorado River Compact, with the Upper Basin states forced by the Supremes (they ride for power, not for the law) to cut back their own uses to meet the 7.5 maf average delivery to the Lower Basin – basically the interstate nightmare (for the upper states) the Compact was meant to address. Call this the stubborn denial option.
A second way would be to accept the evolved eight-way division (seven states plus Mexico) of the use of the river’s water, which was what the seven states wanted to do in 1922, instead of the ‘temporary equitable’ compact they came up with. Percentages for each basin state could be set according to the amount each state was using at the end of the major river development era, say in Y2K (remember that?), when the 70-year average annual flow was ~14.5 maf (1930-2000). Those state percentages of the river’s consumptive use could be retained – but the actual volume of water for each state would gradually diminish as the combination of ‘dry drought’ and ‘heat drought’ continues to diminish the river. Given that losses attributable to climate warming are both everybody’s and nobody’s fault, the losses to each states would be proportionate to their percentage of the river’s consumptive use, with no falling back on seniority, as though it were just a squabble between users. Each state could then either stay with the appropriation doctrine intrastate with junior users bearing the loss, or equitably share out the loss proportionate to use. Call the latter the shared reality option.

A third way lies between stubborn denial and shared reality, and will probably prevail as the default American Way: let money work it out. Municipal and industrial users will continue to work out money-for-water deals with agricultural users, like San Diego and the Metropolitan Water District have done with the Palo Verde and Imperial Valley ag districts, with responsible districts using the money for systemic improvements that minimize the impact of lost water. This is by no means going to ‘dry up’ agriculture. With 75-85 percent of the river’s water being used by agriculture, a doubling of M&I use would only require transfer of 10-15 percent of ag water, although (money being blind to all but profitability) the transfers would probably cause some local tragedies like Crowley County in Colorado where too much water was bought out of a single small irrigation district by Front Range entrepreneurs.
The appropriation doctrine, with its strange ‘property right’ independent of the property for which it was granted, is quite compatible with the money option for resolving water distribution, once over-appropriation is achieved. The idea that water’s seniority in a certain use can be transferred to a totally different use along with the water strikes me as strange – shouldn’t a new use initiate a new right? It is also contradictory to the doctrine’s initial democratic-populist effort to prevent the dominance of big money in water distribution by limiting water rights to what one could put to use. But it does seem to be the American way that everything eventually comes down to money as the base determinant of value.
Enough for today. The elephants in the river. I obviously favor ‘ratifying’ the evolved split of the use of the river, and an equitable proportionate sharing among all states – and within all states – of the consequences of our cultural climate changes. But that will not fly among those who have steadfast faith (senior water right holders) in the appropriation doctrine as the answer to all problems.
The river? It abides, rises and falls with the water table in its surrounding groundwater, and it may occasionally disappear, but it won’t have died, it will just have gone underground until the water table rises again and the ground can’t hold all the water – if we figure out how to let that happen.

On Saturday, June 6, the Colorado River District, in partnership with the Colorado Water Conservation Board, began to release water from Wolford Reservoir as part of a collaborative effort to protect hundreds of water users who depend on the Colorado River from being curtailed due to exceptional drought conditions.
Extremely low snowpack and a warm winter, along with extreme heat in March, prevented the full storage of a critical water supply known as the Historic Users Pool (HUP) which is held in Green Mountain Reservoir (GMR), just north of Silverthorne. Without the protection provided by this supply, hundreds of entities, including towns, HOA’s, and local water districts could have faced curtailment in early June.
The success of this initiative depended on the cooperation of Grand Valley water users, who agreed to temporarily reduce the senior Cameo demand below its full legal limit so these protections could be implemented for other Colorado River water users. By voluntarily curtailing a portion of their own irrigation use, these districts helped keep upstream users whole and delayed a senior call on the river that would have otherwise required the curtailment of HUP beneficiaries.
“Irrigation entities across the Grand Valley chose to reduce water use early in the summer to help build the storage we rely on that was sorely lacking (almost non-existent) due to the warm and dry winter conditions that left us with very little snowpack,” said Roblee Talbott, president of the Orchard Mesa Irrigation District Board of Directors. “What we gained in storage will help carry us further into the season than originally anticipated. Beyond that, we’ve committed to work together to ensure we can finish crops later in the season. While this decision represents some very real risks for the family farms and ranches that sustain our local economy and food supply, it also reflects the strong spirit of collaboration in our Grand Valley agricultural irrigation community.”
“This year has reminded us how connected Western Slope communities truly are,” said Siri Roman, General Manager of the Eagle River Water and Sanitation District. “We are grateful to the Grand Valley water users who voluntarily reduced irrigation to help support upstream communities during these challenging conditions. As drought impacts become more prevalent, we all have a responsibility to use water wisely and support the long-term health of our communities, agriculture, and rivers. In the Eagle River Valley, we are actively working to reduce our outdoor water use and encouraging our customers to make lasting landscaping changes that will decrease water demand for years to come.”
“Having access to this program has been extremely important for our community in western Grand County, and we are grateful for the willingness of the Colorado River District and their partners to work with us,” said Brenda Kellen, board member for the Blue Valley Metropolitan District. “Without this support, we would have struggled to have access to adequate water supplies for our residents this summer. We recognize the challenges involved in managing and protecting water resources, and we appreciate the cooperation and partnership with CRWCD and water users from Grand County to Grand Junction.”

“The drought conditions affecting Colorado this year are creating immense challenges across the state,” said Lauren Ris, Director of the Colorado Water Conservation Board. “The CWCB was pleased to support this effort that demonstrates how partners can work together to develop creative, collaborative solutions that help address immediate drought impacts while providing multiple benefits for water users and the environment. As conditions continue to evolve, we remain committed to working with communities throughout Colorado to explore innovative approaches that strengthen drought resilience and help meet critical water needs.”
“Our duty is to help protect West Slope water users during exceptionally difficult conditions like the ones they are facing this year, and we have been navigating a complex and rapidly changing situation to determine how a limited supply of water can do the most good for the most people,” said ColoradoRiver District General Manager Andy Mueller. “These releases are designed to help a broad array of water users, but they are not a substitute for ongoing conservation. We expect that beneficiaries will do their part by reducing demand where possible, including cutting outdoor domestic watering to one day per week.”
At its April 2026 meeting, the Colorado River District Board of Directors approved $450,000 from the Community Funding Partnership program for use in emergency drought response efforts. The Colorado Water Conservation Board also committed just over $585,000 to the effort at its May meeting in recognition that the releases will be multi-beneficial, supporting in-stream flow benefits, along with municipal, domestic, and irrigation needs. These funds will support the release of over 15,000 acre-feet of water currently stored in Wolford and Ruedi Reservoirs to protect both municipal and agricultural users along the Colorado River and its major tributaries from Grand County to the Grand Valley. These releases will also support in-stream flow needs providing fishery benefits that mitigate high water temperatures and the loss of aquatic habitat due to critically dry conditions.
As of June 17, the HUP was a little more than half full with approximately 40,800 acre-feet of water stored.
The initial release from Wolford Reservoir, which began on June 6, is currently around 9 cfs, and is intended to specifically protect the indoor water uses in Summit, Grand and Eagle counties. Between now and next spring, approximately 3,000 acre-feet of water is available for this purpose from both Wolford and Ruedi Reservoirs.
An additional 12,000-acre-feet of water will also be made available for irrigation and agricultural production in the Grand Valley throughout the summer until supplies run out.
The Colorado River District appreciates the support of the leadership and staff of the Division 5 engineer’s office in the implementation of this effort, as well as the work of the Colorado Water Conservation Board staff and directors to expedite funding, a temporary loan for instream flow use, and emergency substitute water supply plan approval.

Twenty years ago, some might have hoped that drought in the Colorado River Basin would diminish or disappear altogether.
Hope remains but of a distinctly diminished variety. Will the arriving El Niño will bring a rare deluge, bringing the water levels of Lake Powell from the brink of deadpool, too low to release water downstream?
Two books have been written in the last few years with “deadpool” in their titles, indicating how close to the edge we have been. If not for a very big snow year in 2022-2023, we might well have been there in 2023. Now, we’re in the same place or worse.
It’s very possible that Lake Powell will have too little water by September to generate electricity. That is called minimum power pool. Deadpool lies just a few steps below.
Unlike 20 years ago, nobody seems to harbor delusions that this problem will be solved by a turn of nature. As for the El Niño, it may help but Brad Udall advised against too much hope hedging.
Cavitation at the Glen Canyon Dam, the cause of the emergency in 1983 via Flow Science.
Speaking at the Colorado River conference at the University of Colorado Law School in early June, Udall explained that El Niño increased the odds of large impacts as it did in 1983. That year Glen Canyon Dam almost broke with the runoff of 24 million acre-feet. Another big year was 1997 with 19 million acre-feet. And then produced 13.4 million in 2016. Those exceptional years aside, El Niño can be sort of a bust, said Udall, a scientist and scholar affiliated with Colorado State University.
The evidence continues to strengthen that the warming climate — a climate caused by growing greenhouse gas emissions — will continue to rob the river of water. And, as in the past few decades, the warm temperatures will filch water at larger and large volumes.
Udall had been tasked with summarizing what the 2026 water year that ends in September could be in the context of long-term trends and short-term impacts.
NOAA’s Colorado River Basin Forecast Center had predicted 13% of average runoff flows, just 800,000 acre-feet, compared to the more average 6 million. “It’s below even 2002, which was the lowest year on record, just about a million,” said Udall.

As is now widely understood, those who met in Santa Fe in November 1922 to create a framework for sharing the Colorado River had assumed river flows from the upper basin states would be plentiful, 17.5 to 18 million acre-feet. They erred grievously on the side of optimism. The 20thcentury average was 15.2 million acre-feet, and this century bent downward even more. Since 2019, the average has been 10.2 million acre-feet.

Realizing how on-target climate change models have been both comforting and chilling, consider a chapter by the late John Opie, the author of several books about the Ogallala Aquifer. In his concluding chapter in a book published in 1998 called “Sense of he American West,” he mentioned predictions that global temperatures would rise1.5 degrees C by 2030. So far, we’re at 1.2 to 1.35 degrees C.
In the American Southwest, we’re heating more rapidly, about 3.5 degrees C per century, according to a paper issued by the Rhodium Group.
We had a sharp taste of that in March. Temperatures across the Colorado River Basin that month averaged 9 degrees F above the 20th century average. In Colorado, Fort Collins had a new record for the first day above 90 degrees in records going back to 1895. This year that first 90-degree day arrived in March. This year’s first skipped over April. The previous earliest was in May.
What will increased heat mean in terms of precipitation? The short answer is that it increases evaporation and transpiration. So, of the snow or rain that falls, less of it emerges as water in downstream reservoirs or, for that matter, in transmountain diversions.
Taking a more global perspective, Udall pointed to a natural phenomenon that became apparent to scientists only in 1997, called the Pacific Decadal Oscillation. It alters jet streams and storm tracks in the American West. Like El Niño and La Nina, it has different phases. The negative phase of the Pacific Decadal Oscillator pushes storm tracks north, meaning drier conditions in the Colorado River Basin.
Now it seems stuck, according to a paper issued by scientists in 2025. The scientists claim this trend is largely driven by human emissions of aerosols. They cooled the planet, but as we cease their emissions, the effect is to warm the planet. The takeaway from that paper is as long as greenhouse gas emission trends continue, the Pacific Decadal Oscillation will remain stuck, producing drought in the Southwestern states.
Another recent paper examined the North Pacific Ocean and the response to changes in the atmosphere during the last 6,000 years. The takeaway is that the models had under-appreciated the effect of warming, which causes 20% precipitation reductions.
“And I’ll note a 20% decline in precipitation is probably like a 50% decline in river flow,” said Udall.
In other words, 90% of the heat caused by the thickening concentration of greenhouse gases in the atmosphere goes into the ocean, and scientists are still piecing together how that heat in the ocean then affects the climate for the Colorado River Basin.
Even if we reduced our greenhouse gas emissions immediately, the heat will remain for hundreds and then thousands of years.
Think we might see a return to even the 15.2 million acre-feet of the 20th century at Lee Ferry? Forget about it. We might get lucky with an El Niño, but then again, said Udall, the evidence doesn’t support much optimism. The more grounded hope is that the meager snowfall and extraordinary warmth of the last year does not come with an echo this coming winter.

June 23, 2026
Desalination. Pipelines. Cloud seeding. Those are just a few ideas for how the Trump administration should save the desiccated waterway.
The crisis on the Colorado River is simple: The seven Western states that border the essential waterway use more water than it contains. Chronic overuse [ed. allowed and caused by the “Law of the River”] has drained its two largest reservoirs, Lake Powell and Lake Mead, and a two-decade drought cycle has pushed them to the point of collapse.
The dream solution to this crisis is an agreement among all involved to use less water. Such a deal would decide who must reduce consumption, which means asking which cities would ban irrigating lawns and washing cars and which farmers would rip up their fields.
This has proven impossible. The states have been trying to work this out since the last dry spell, in 2022, but talks have ended in frustration and name-calling. The main sticking point is between the Upper Basin states, led by Colorado and Utah (along with Wyoming and New Mexico), and the Lower Basin states of Arizona, California, and Nevada. Each side believes the other has a legal and a moral responsibility to cut usage during dry years. The stalemate means the Trump administration must design a schedule of restrictions ahead of a crucial deadline in September. So far, Interior Secretary Doug Burgum has balked at resolving the quarrel.
Instead, the administration is turning to a far less controversial plan: Throw money at the problem. The Interior Department and Congress are pondering a slew of projects that could increase supply — a reversal of President Trump’s zeal for cutting federal grants. The seven state governors have sent Washington a “wish list” of over $50 billion, and several startups have their hands out as well.
Federal investment makes sense given the scale of the problem and the intractable impasse, said Jennifer Pitt, the Colorado River program director at the National Audubon Society and an expert on the governance of the river.
“It is something easier for people to agree on,” she said. “This is a slow moving crisis, but it is a crisis, and we do see the federal funding come in to address crises in other parts of the country. Just because this is a slow moving one doesn’t make it any less worthy.”
During a Senate committee hearing last week, the Interior Department’s top water official, Andrea Travnicek, said the agency has yet to vet the wish list. She didn’t offer a specific funding request, and urged lawmakers to be “thoughtful” about how they spend taxpayer money. But senators in both parties seemed to encourage new investments. “The basin should not be forced to choose between stabilizing the present and negotiating the future,” said Senator Martin Heinrich, a Democrat from New Mexico.
The possibility of new funding marks a return to the policy of Joe Biden’s administration. During the last extreme drought in 2022, the Interior Department paid farmers billions to leave their fields fallow, but that money, from the Inflation Reduction Act, has almost run dry.
The difference now is that the roster of proposals is far more ambitious, and some far less certain to bolster the basin’s water supply. They range from desalination plants and desert groundwater pipelines to forest ecosystem restoration.
Here are a few of the major solutions state officials and companies are proposing.

Desalination
As the Colorado River crisis has deepened, some cities in the Southwest have eyed desalination, which extracts salt from sea water. A company called Poseidon Water opened such a plant in San Diego in 2015 and tried for decades to open another in Los Angeles. The wish list to the Interior Department requests as much as $6 billion to build one across the border in the Mexican state of Baja California to supplement Arizona’s vanishing Colorado River supplies.
The Interior Department also signed an agreement in early June with San Diego’s water agency that explains how that plant would help. Rather than sending treated seawater inland, states would pay the city to take less from the Colorado River. Arizona stands to lose the most water during drought years, and it would be the most likely to participate in that exchange.
But desalination is expensive, requires enormous amounts of electricity, and state-of-the-art industrial technology. The Poseidon facility cost $1 billion, but San Diego has diversified its water portfolio so much that it no longer needs all the water it must purchase from the plant. Trading water could help it offset some of that cost.
Taming tech and power
Nevada uses less water than any state on the river and has cut usage in Las Vegas by replacing grass with artificial turf. It is now seeking money to slake some of its last thirsty industries: power plants and data centers. These facilities need a fraction of what agriculture requires, but they dominate usage in the Silver State.
The state’s wish list includes $300 million to retrofit its largest natural gas plant and reduce water consumption by an amount equivalent to more than 3,000 average homes. It also seeks $650 million to install zero-water cooling systems in airports, schools, and industrial facilities. These closed-loop systems, which recirculate the same cooled water or, in the case of data centers, blast hot servers with cold air, have become more popular in Western states amid concerns about the tech boom’s growing thirst.

Squeezing rain from the clouds
Whereas Lower Basin states like Arizona and California can draw from the Colorado River’s big reservoirs on demand, northern states at its headwaters only receive the rain and snow that feed it.
These Upper Basin states have been trying for decades to engineer more precipitation, with support from Washington, D.C. It sounds futuristic, but cloud seeding — spraying salt or silver iodide into clouds, forcing them to release water they might otherwise retain — has proven fairly effective on a small scale. Utah spends a few million dollars each year doing this, and officials say it could boost annual snowpack by as much as 10 percent.
In addition, a few startups are pitching cheaper and more scalable versions of this technology. Rain Enhancement, a Florida-based outfit, says it has brought about 15,000 homes’ worth of rain to a river tributary in Utah this year; another, Rainmaker, says it can produce 1,000 times that much by 2031. That’s enough to close the supply gap on the river. That promise is fanciful, but these companies could secure federal funding from an administration that loves the tech industry.
Mining a hoard of desert groundwater
The West teems with companies that have promised miracles, from building a 300-mile pipeline to tapping a hoard of groundwater in Nevada. But perhaps no project has had a longer and more turbulent history than Cadiz, a proposal, almost 30 years old, to export groundwater from an aquifer in the Mojave Desert.
This has drawn vicious opposition from environmentalists and the late California Senator Dianne Feinstein, who called it a “grave threat” to the desert. Cadiz experienced several setbacks during the Biden administration: It lost a federal permit, California ended its pipeline lease, Arizona declined to support it, and its stock price fell to almost zero. But Susan Kennedy, its CEO, says Cadiz is flowing again with a funding agreement from the Interior Department to study exchanges between Cadiz and the Colorado River.
The company still needs to finish two pipelines, one to the Central Valley and another to the aqueduct that carries Colorado River water to California. It also must build a plant to remove contaminants in the water, but Kennedy believes she can have the tap running by 2028.
“This isn’t a competition; it’s an all-of-the-above situation,” she said of the situation on the river. That may be so, but the seven states did not include Cadiz on the wish list sent the Interior Department.

“Colorado River Negotiators” in Cataract Canyon. No clue how the gal in the Earth First! shirt slipped in there? Photo credit: Wild Words
Click the link to read the article on the Wild Words website (Morgan Sjogren):
On Monday, June 15, a new cadre of representatives from seven Colorado River Basin states convened below Cataract Canyon for water negotiations. The open-air meeting was held in an eddy flanked by a thick layer of the Dominy Formation.1 Silt tumbled into the banks in low runoff conditions as the Upper Basin (Colorado, Utah, Wyoming, New Mexico) and Lower Basin (California, Arizona, Nevada) prepared statements about how to reduce over-consumption of the shrinking Colorado River.
The impromptu Colorado River standoff theater was not real. It was a beach game intended to explain water overallocation. That it still resulted in imaginary litigation speaks loudly to this moment in history. The ability to take this lunchtime activity a little too literally was also because the participants were members of Glen Canyon Institute and guides for Holiday River Expeditions. These shenanigans took place in the final hours of a five-day river trip in Cataract Canyon to support GCI’s ongoing efforts for the restoration of Glen Canyon.
The group was certainly highly astute to Colorado River current events to throw down such an intricate dialogue on the spot. Instead of making a list of the very real solutions to distribute Colorado River water to forty million people, the group recognized what is literally standing in the way: seven state representatives who are just as responsible for the looming potential for a Colorado River crash as Glen Canyon Dam.
The basin-wide impasse is by far the most frustrating aspect of explaining the current problems and future management of the Colorado River. The potential solutions are abundant, even obvious. Everyone in the basin needs to use less water.
Other critical changes, like giving all thirty Colorado River-connected tribes a seat at the negotiating table and updating the 1922 Colorado River Compact to actually meet river flows where they are at in 2026 (an average of 12.5 million acre-feet down from 15 million acre-feet a century ago), are long overdue. Not to mention, ensuring the Colorado River’s right to flow, in line with the Colorado River Indian Tribe’s legal personhood status for the river under their Tribal law.
Beyond the dam, is the Colorado River’s most glaring problem, both concealed and amplified by the water crisis-–is this what democracy is supposed to look like? And what can a citizen of the Colorado River watershed actually do about it?
Despite this broken system, advocacy, especially in the long-term, can move the needle. Until recently, opposition to Glen Canyon Dam was viewed by some as a fringe environmental cult.
Yet Glen Canyon Institute has maintained a constant presence on the front lines of this issue. Since 1996, GCI “embarked upon a multi-year campaign to protect and restore Glen Canyon and reverse the decline of Grand Canyon’s fragile ecosystem.” The Fill Mead First plan takes a hard look at the long-term realities of keeping two major reservoirs, Powell and Mead, more than half empty. Then, in 2024, the Bureau of Reclamation made an announcement that opened minds (and some hearts) to consider that Glen Canyon Dam is a major part of the current problem.
Through persistent love and devotion of these advocacy efforts, awareness for the recovery of Glen Canyon continues to gain momentum. So does dealing with Glen Canyon Dam’s outdated infrastructure which is becoming more mainstream and realistic everyday. In a recent letter, the Lower Basin states urged the Bureau of Reclamation to make dam modifications.2
While it is electrifying to be on the pulse of a major change that stands to benefit Glen Canyon and the lower Colorado River, the current negotiation process is still a dystopian nightmare circus.3

For some folks, like myself, this shit show is so fascinating that we are keen to immerse ourselves in the muck. However, even if you care deeply for the Colorado River, this can be overwhelming, especially amid the persistant horrors of this era. Naturally, our instinct may be to turn away. This came up during a riverside policy talk on the trip led by GCI’s projects and development manager Anna Penner and me. With so much going on and the constant information overload online, it is important to trust your gut instinct and give yourself space away from the news. Just don’t pull your heart from the Colorado River itself. [ed. emphasis mine]
The Colorado River carries hope. The side effects of drought, overallocation, and indecision is the steady return of a free flowing Colorado River and Glen Canyon emerging from a shrinking reservoir. I’ve written before that many of us were too late to experience Glen Canyon before the dam, but we are now right on time to witness its resurrection. Cataract Canyon is an ideal place to experience the changes in motion. From muddy sediment-rich river flows and returning rapids to strongholds of native plants like box elders and seep willows propagating in tributary canyons.

For one guest, Tom, these watershed moments for Glen Canyon are major bookends in his life. As a young lad, his family crossed the old Hite Ferry at Dandy Crossing in their station wagon during a road trip. They then drove up the rock-rutted and sandy North Wash, sans road, before it became Highway 95. He also boated on Lake Powell in 1965, before it filled completely, and vividly recalls seeing the fully exposed Hole-in-the-Rock site. Now age seventy seven, Tom and his lifelong friend Paul make time every year to return to the Colorado River with GCI. He has been a member for twenty-one years

This was Aaron’s first Cataract River trip, and a deserved reward for living with my Colorado River obsession. His perpetual and ever-widening smile affirmed how important quality time with the river is, now and always. Post-trip, he told me his favorite part of the trip was “watching the swirling eddy lines at sunset, while sitting on the beach with the group.”
Right now, we are all in an eddy. The decisions made, or not, in 2026 will ripple beyond our lifetime. But so will our unrelenting love for the river and the water that sustains life in the West. Impossible dreams, like the EarthFirst! symbolic crack in the dam, may come to life in yet unimagined ways, so long as we do not give up.

To this, I pause and take another swig of whiskey and muddy water. This spring, I had more than one interview with so-called major environmental groups that sounded more like public relations agents for Glen Canyon Dam and Lake Powell.
Lee continued:
Exhausting? Perhaps. But better tired than apathetic. With tin cups filled with muddy water, this moment asks us to stand with all who have defended the Colorado River in the past and will continue on into the future. Protecting what we love is a journey without end.

WASHINGTON – The chair of the Senate Energy and Natural Resources Committee warned Arizona and two other states that rely on the Colorado River on Wednesday that they will lose access to hundreds of millions in conservation aid if they pursue litigation over water rights.
Roughly $354 million is still available under a 2022 climate law. But the funds expire at the end of September.
“States that choose to sue their fellow basin states over Colorado River operations should not expect Congress to reward that decision with additional federal funding,” Sen. Mike Lee, a Republican from Utah – one of the four Upper Basin states, said at the outset of a hearing on the stalemate among the seven states that share the river. “Federal taxpayers should not be asked to subsidize litigation among the states.”

Arizona, California and Nevada have been at odds with Colorado, Utah, New Mexico and Wyoming over how to divide the dwindling water supply when the most recent 19-year deal expires at the end of 2026.
The funds Lee threatened to block are a key element of the Lower Basin’s most recent proposal from May 1, which relies on the funding to incentivize voluntary water conservation as an alternative to mandatory cuts.
The $354 million comes from the Inflation Reduction Act signed in 2022 by President Joe Biden, which set aside $4 billion for drought mitigation and compensation for voluntary conservation. Funds that remain unused when the current fiscal year ends Sept. 30 will revert to the Treasury.
He chastised officials in the Lower Basin states for, among other things, taking out newspaper ads attacking Upper Basin states.
Negotiators appeared to be “preparing actively for litigation,” he said – and in fact, key officials in both camps have told Cronkite News in recent days they are preparing for that possibility.
Congress “will not be a bystander in this process,” Lee said, noting that under the Constitution, Congress holds approval authority over any long-term interstate compact.
He also expressed sympathy with the Upper Basin’s stance, warning that any proposal asking those states to absorb greater operational burdens without regard to the river’s existing legal framework “will face a difficult path forward” in Congress.
The chairman framed the moment as a failure of collective will, cataloguing a string of missed deadlines. “The basin can no longer afford to wait,” he said.
After Lee delivered his rebuke, Arizona Sen. Ruben Gallego, a Democrat, pressed the Trump administration from the opposite direction.
Gallego asked Andrea Travnicek, assistant secretary for water and science at the Department of the Interior, how the department plans to weigh Arizona’s economic stakes as it finalizes its decision.
“The Colorado River is a lifeline for Arizona,” Gallego said, noting the state is home to the most advanced semiconductor manufacturing hub in the Western Hemisphere and that the success of its industries are essential to the nation.
“The technological industries, the domestic food supply, and energy security are all top priorities for the United States, including the president’s agenda,” he said.
Travnicek said the department cannot accept either the May 1 proposal from the Lower Basin nor the latest Upper Basin proposal as they currently stand.
“We have some concerns and areas where we think that there should be adjustments,” she said.
She confirmed that the Interior Department is coordinating with the Energy Department and U.S. Department of Agriculture, among other agencies. She said an interagency water subcabinet meeting will be held Thursday.
The hearing laid bare the tension that has made a seven-state deal so elusive, with senators from both basins on hand.
Travnicek fielded pressure from both directions without committing to either.
The stakes are straightforward and very high.
Decades of drought have pushed water levels to dangerously low levels even as demand and population grow. The river now provides barely half the amount of water each basin has been legally entitled to draw.
“Delay carries its own consequences,” Lee said, “and the basin can no longer afford to wait.”
THE NEWS:Sen. Mike Lee, the ultra-MAGA Utah Republican, failed once again to diminish public lands protections when his bid to use the Congressional Review Act to revoke Grand Staircase-Escalante National Monument’s management plan expired before getting a vote.
THE CONTEXT: This spring, Lee and Rep. Celeste Maloy, also a Utah Republican, introduced a joint resolution of disapproval in both houses of Congress aimed at repealing the 2024 management plan. That started the clock ticking on a 60-day time-limit for a simple majority vote to overturn the plan. The deadline passed on June 11 without any action, meaning that any effort to toss the plan now would be subject to the Senate filibuster, so would need 60 votes to pass — a highly unlikely prospect.
Had the resolution passed, the national monument’s management would have reverted back to the weak and inadequate 2020 Trump I-era plan, which allowed more grazing, more damaging “vegetation management,” and more off-road vehicle use. Plus the 2020 plan only covered the 1 million acres left in the national monument after Trump removed about 900,000 acres from its boundaries, meaning almost half of the national monument would in a sort of management limbo.
This would have sown chaos and confusion, yet it wouldn’t have diminished the national monument or the protections that were baked into the establishing proclamation. The monument boundaries would have remained intact, along with the prohibition on new oil and gas drilling, mining claims, and other energy development.
Nevertheless, it clearly was intended as an attack on the national monument and the attendant protections, which have been a sore spot for Utah sagebrush rebel-leaning politicians since Bill Clinton established it under the Antiquities Act 30 years ago this September. What Maloy or Lee hoped to actually achieve with the attack is a little less clear, even if it had hit its target.
Maloy likely was trying to brush up on her anti-federal-land-management credentials before what could be a bruising primary. Her challenger is notorious sagebrush rebel Phil Lyman, who led an illegal OHV-ride down the archaeologically rich Recapture Canyon in 2014 to protest what he called “federal overreach.”
So far, Maloy is winning the fundraising race by a healthy margin. Utah Political Watchreports that the Defend our Values Super PAC run by former Rep. Chris Stewart, R-Utah, just donated $900,000 to Maloy’s campaign. The American Conservation Coalition PAC, which says it “helps elect leaders who champion American energy dominance, environmental conservation, and cutting-edge innovation,” has spent over $150,000 in support of Maloy, as well. Maloy isn’t exactly living up to the conservation part of that, but I’m not sure the PAC folks care too much about it, either.
And then there’s Lee. Sometimes it feels as if he’s taking up the tasks Project 2025 guided the Trump administration to execute, but that the administration has backed off from because of how deeply unpopular they have turned out to be. It’s almost as if the administration is tasking Lee with feeding some red meat to the MAGA base, but also is setting him up to fail.

THE NEWS: The U.S. Interior Department is launching a “review” of rock climbing management and wilderness study area policies. On June 15 it opened the 60-day public comment period on its proposals to establish “a consistent approach to recreational rock climbing management across designated wilderness areas,” and to evaluate whether “existing wilderness study areas and lands with wilderness characteristic policies should be updated, clarified, or revised.”
THE CONTEXT: Any time the Trump administration decides to “review” something, it pays to be wary, since more often than not the review leads to the evisceration of some sort of environmental protection. They tend to couch it in euphemisms, however, such as this bit from an Interior press release: “… Interior is focused on expanding outdoor recreation opportunities, removing unnecessary barriers to access, and use, and managing public lands in a way that benefits the American people.”
Wilderness areas are designated by Congress and are governed by a set of specific rules that can’t be altered by the administration. However, the question of whether installing fixed climbing bolts and anchors is permitted or not is vague and has shifted over the years (what is clear is that power drills cannot be used to install them). The administration is looking to clear this up, and to allow fixed anchors in wilderness areas as long as they follow certain guidelines.
Wilderness study areas share many of the same qualities and protections as wilderness areas, but have not been designated as such by Congress. In 1976, Congress tasked the BLM with identifying potential wilderness areas within its domain and make recommendations regarding them. Those that were identified and fit certain criteria but not designated became wilderness study areas, or WSAs. There are currently 491 wilderness study areas covering over 11 million acres. Look at a map of areas that have large swaths of BLM land — particularly in Utah — and you’ll almost certainly find a few.
The Federal Land Policy Management Act directed the BLM to manage the WSAs “in a manner so as not to impair the suitability of such areas for preservation as wilderness”and prevent “unnecessary or undue degradation.” In other words, you couldn’t build a permanent road through a WSA because that would preclude it from being designated as a wilderness area later.
This leaves room for agency interpretation. The current BLM policy, carried out in accordance with a 2012 manual, is to “continue resource uses on land designated as WSAs in a manner that maintains the area’s suitability for preservation as wilderness.” Under that policy, the agency almost certainly would not permit a road through a WSA, because that would preclude it from being designated as a wilderness area later. And, according to the memo, it most likely would not allow motorized or mountain bike use in a WSA.
The current administration is unlikely to get away with allowing permanent roads in WSAs. However, given its language about removing barriers to access, one can expect it to apply a broader and more permissive interpretation of the non-impairment standard to its policies. This might mean allowing motorized vehicle or mountain bike use within WSAs on existing trails, for example, or even some logging or small-scale mining, so long as the agency officials could convince themselves that it would be cleaned up later.
Finally, the BLM also has a policy for managing lands with wilderness characteristics that are not WSAs or designated wilderness areas. The administration is reviewing this policy, as well.
Interior announced all of these policies in one press release, but you need to comment on them individually. Here’s how:

Guest Commentary: A Fair Allocation for the Colorado River
by Levi Tenen
This summer is the last chance for seven Western states to allocate the Colorado River voluntarily before the federal government steps in1. Gridlock persists: Lower Basin states (California, Arizona, and Nevada) have offered to reduce their water usage the most, but they believe that Upper Basin States (Colorado, New Mexico, Wyoming, and Utah) ought to reduce their usage as well if the region dries up too much.2 The Upper Basin states reject this proposal, refusing to reduce the amount of water that was allotted to them under previous agreements.3 The federal government has proposed solutions of its own, all of which seem to favor the Upper Basin states.4
The debate raises fundamental questions: how should resources be allocated in times of scarcity, and do past agreements matter today? From my research in ethics, I think there is an answer, and one that has not been noticed by others. Justice demands that Upper Basin states give up some of their allotted, promised water, but Lower Basin states must greatly limit their water usage and—the new idea—Lower Basin states ought to pay for the extra water they receive.5
To see why, consider a thought experiment from philosopher Jeremy Waldron6: Imagine you and I own ranches in an arid region. We drill wells on our respective properties and enjoy plentiful water. Good times come to an end, however, when a drought sets in and my well runs dry. Unable to relocate, I am stuck in a dire circumstance. Due to the geography of the area, however, you continue to have a surplus of water. What, if anything, do you owe me? Without anyone else around to help me, are you obligated to share your water? The answer is yes, to an extent. It would be wrong, for instance, if you prevented me access to your well just to let the water go unused, leaving me to die. It would also be wrong if you kept me from your well so that you could build a nice new pool, or even so that you could increase your wealth by adding many more head of cattle, all while I perish nearby. Put simply, in times of scarcity and desperation, justice limits a person’s property rights. Justice will never require you to endanger yourself, but more modest sacrifices can become obligatory.
What most people miss, however, is that obligations often fall onto the recipients of aid. Return to the above case. First, even though water is scarce, other resources may not be. So, while you are obliged to give me water, if I have money, labor, or something else to give in return, I ought to do so. It would be unfair, after all, for me to hold onto large amounts of disposable wealth and take your water, leaving you altogether worse off and me only better off.
Secondly, even though I receive water from you, I cannot use it however I want. For, I do not have the right to an endless amount of your water. The water you owe me is only for the basic conditions of life, not for wasting away or for self-serving, economic growth. So, I mustn’t add more cattle to my ranch or build a pretty fountain in my courtyard. Indeed, if scarcity persists, I need to reduce my water consumption greatly, scaling back my ranch operations. To do otherwise would be to limit your future opportunity unjustly.
Carried over to the Colorado River, this much then seems clear: Upper Basin states ought to give some of their unused water to Lower Basin states, even though they all previously agreed to allocate that water to the Upper Basin. The scarce and desperate times limit the past agreements, particularly because the scarcity was unforeseen. And make no mistake: the Lower Basin states are facing dire times. Tens of millions of people in those states depend on the river for drinking water.7 Moreover, 70% of the water goes to food production, with the majority going towards crops in Lower Basin states.8 Running out of water is an existential threat to the cities and peoples in the Lower Basin, and it is a threat to food security the nation over.9
However, the Lower Basin states ought to purchase the water from Upper Basin states and they need to minimize their burden on those states, even if that means ceasing new housing developments and industrial projects. Perhaps if the Lower Basin states add these conditions to their offer, negotiations will move forward and the Upper Basin will accept their share of the burden: sending some of their allotted water downstream.

June 18, 2026
In the next few weeks, we will share a few graphs and charts that we find informative in understanding today’s water supply crisis on the Colorado River. This short paper concerns the present status of reservoir storage.
IN BRIEF
In 2026 and for only the third time in the 21st century, there was no accumulation, and no recovery, of total Basin live storage6 during the snowmelt season. Nor was there any accumulation or recovery of total live storage in Lake Powell and Lake Mead during the 2026 snowmelt season. Total Basin live storage (hereafter, total Basin storage) is all the water available in the Colorado River Basin’s reservoir “savings account” and stored in reservoirs within the watershed.7 On June 1, total Basin storage was 22.94 million acre feet (maf), only 1.62 maf above the previous minimum of March 20238 and less than 2 years supply at the current rate at which water is consumptively used or lost in the Basin. Total Basin storage will almost certainly drop to less than the previous record minimum by March 2027.
THE PRESENT CONDITION
On June 1, 2026, total Basin storage in 46 reservoirs in the Colorado River Basin was 22.94 maf, 9 39% of the content of those same reservoirs in late August 1999, the last time those reservoirs were relatively full.10 On June 1, Lake Mead held 33% of the Basin’s active storage, 32% was in 42 reservoirs upstream from Lake Powell, 25% in Lake Powell, and 10% in Lake Mohave and Lake Havasu. The combined live storage in Lake Mead and Lake Powell was 28% of the total live storage of those two reservoirs in late summer 1999.11
Why Total Basin Storage?
Most policy analysis of reservoir storage in the Colorado River Basin focuses on Lake Powell and Lake Mead or, alternatively, on all federally managed reservoirs in the Basin. These reservoirs are the focus of ongoing negotiations among the Basin states and will be impacted by impending management decisions by the federal government. On June 1, 89% of total Basin storage was held in 12 federally managed reservoirs.12 Slightly more than 60% of live storage upstream from Lake Powell was held in 8 federally managed reservoirs.
Total Basin storage is the total amount of water stored in reservoirs in the Colorado River watershed. In addition to the 12 federally managed reservoirs, Basin storage includes federal project reservoirs managed by other entities and non-federal reservoirs managed by municipal water providers and water conservation and conservancy districts. Some of the non-federal reservoirs act as forebays that facilitate trans-basin diversions to the Colorado Front Range or Utah’s Wasatch Front. Water stored in these non-federally managed reservoirs is not subject to current or proposed federal operating guidelines. In the Upper Basin, however, water stored in the non-federally managed reservoirs is one determinant of total Upper Basin consumptive use.Therefore, the status of storage in all the Basin’s reservoirs is an indicator of the overall condition of the Colorado River reservoir system and its ability to buffer continued declining inflow. Transfer of water from one reservoir to another, such as the on-going transfer from Flaming Gorge Reservoir to Lake Powell, does not affect total Basin storage. Although such management policy is critical to protecting dam infrastructure and maintaining realistically accessible storage in Lake Powell, 13 such policy merely shifts the location of the Basin’s deck chairs. What matters is whether the ship is sinking. [ed, emphasis mine]
Accumulation Period And Depletion Period
In terms of reservoir storage, we have previously distinguished two periods of the year – the period of reservoir rise (i.e., accumulation period) and the period of reservoir decline (i.e., depletion period).14 In terms of total Basin storage, the 2-3 month long accumulation period typically begins in mid-April, although it has begun as early as mid-March (Supplemental Table 1). The accumulation period typically ends in early July but has sometimes ended in early June and as late as early August. In rare cases, as discussed below, there has been no accumulation. The depletion period typically occurs from mid-summer until the following spring and lasts 9-10 months.
BASINWIDE STORAGE SHOWS CONTINUED DOWNWARD TREND DESPITE PERIODIC WET WINTERS
Basin Reservoirs in Spring 2023 Were at an Unprecedented Low.
Figure 1 shows total live storage in 46 reservoirs during the past 3.5 years. The minimum amount of water in those reservoirs was on March 14, 2023, immediately before snowmelt began from the winter 2022/2023 snowpack. At that time, the Basin’s reservoirs only held 21.32 maf. Total Basin storage had not been that low since May 1965 when the newly constructed Colorado River Storage Project reservoirs were beginning to fill.15
Figure 1. Graph showing total storage in 46 reservoirs in the Colorado River Basin since January 1, 2023. The minimum amount during this period occurred in mid-March 2023, when total storage was less than at any time since late May 1965. The amount of increase or decrease in total Basin storage during the accumulation and depletion periods of each year are shown. Updated to June 14, 2026.
Snowmelt in 2023 was unusually large for the 21st century, and reservoir storage significantly recovered. The 8.38 maf increase in reservoir storage during the 2023 accumulation period was the second largest single-year increase of the 21st century and resulted from the second largest unregulated inflow to Lake Powell of the 21st century.16 The Basin’s reservoirs were subsequently drawn down by only 2.15 maf between July 13, 2023, and April 17, 2024, the smallest depletion period since at least 2010. Unregulated inflow to Lake Powell in Water Year (WY) 2024, primarily due to the 2024 snowmelt season, was typical of the 21st century,17 and the Basin’s reservoirs recovered 2.45 maf. Because Basin reservoir recovery exceeded the drawdown during the preceding 2023-2024 depletion period, Basin storage reached its highest recent peak at the beginning of the 2024-2025 depletion period.18
The gains of 2023 and 2024 were subsequently lost between summer 2024 and today, because depletion exceeded accumulation. In spring 2027, total Basin storage is likely to be less than it was in March 2023.
In early July 2024, the multi-year downward turn of reservoir storage began. The Basin’s reservoirs were depleted by 3.60 maf during the 2024-2025 depletion period, more than 1 maf greater than the preceding accumulation. Unregulated inflow to Lake Powell in WY2025 was the fourth driest of the 21st century19, and the Basin’s reservoirs only accumulated 0.55 maf, a small amount. Despite hard-fought, politically contentious, and economically expensive system conservation and assigned water efforts as well as a wet fall in the southern part of the Basin, the Basin’s reservoirs were depleted by 4.00 million af during the 2025-2026 depletion period.20 The most probable unregulated inflow to Lake Powell in WY2026 is forecast to be 3.40 maf, the second lowest inflow of the 21st century.21 There will be no accumulation this year.22
As of June 1, 2026, the Basin’s total storage was only 1.62 maf more than total storage at its record-breaking low in March 2023. It is likely that Basin storage in spring 2027, before the 2027 accumulation season begins, will be lower than at any time since 1965, because depletion during the 2016-2027 period will probably exceed 1.62 maf.23
The depletion of reservoir storage that began in summer 2024 occurred despite a significant effort to reduce Lower Basin water use. Water use in California and Arizona in Calendar Year (CY) 2025 was the lowest and third lowest, respectively, since CY2010, and use in those two states in CY2024 was the fourth lowest since CY2010. Water use in Arizona in CY2026 is forecast to be the lowest since CY2010. Upper Basin use in CY2024 was typical for the period CY2010-CY2024; Upper Basin use data for CY2025 are not yet available.
Despite each spring’s snowmelt inflow, each part of the Basin’s reservoir system that stores water – Lake Mead, Lake Powell, and the reservoirs upstream from Lake Powell – has declined since their recent maximums in summer 2024.
Lake Mead typically peaks between January and March and then declines until August (Fig. 2). This pattern contrasts from that of Lake Powell and of reservoirs further upstream. The winter peaks of Lake Mead in 2024, 2025, and 2026 have been progressively lower each year, and the summer minimums have also been lower each year. In 2026, Lake Mead peaked on February 28 and lost 1.23 maf between March 1 and June 1 and will probably continue to drop during the rest of summer. On June 1, 2026, Lake Mead stored only 0.34 maf more than its recent minimum of January 1, 2023.24
Figure 2. Graph showing live storage in Lake Mead, Lake Powell, in 42 reservoirs upstream from Lake Powell, and in Lake Mohave and Lake Havasu since January 1, 2023. Updated to June 14, 2026.
In the last two years, Lake Powell has dropped more than other reservoirs. Lake Powell lost more than 4 maf of stored water since early July 2024. In 2026, Lake Powell steadily declined from the beginning of the year until May 7 and stabilized following the onset of snowmelt runoff, increased releases from Flaming Gorge Reservoir, and reduction of releases at Glen Canyon Dam.25 On June 1, decline in Lake Powell resumed. The total live storage in Lake Mead and Lake Powell on June 1 was 13.38 maf, significantly less than the capacity of either individual reservoir.
Total storage in 42 reservoirs upstream from Lake Powell also declined during the past 3.5 years. Those reservoirs rise every spring and typically recover until sometime in June or July. Presently, many reservoirs in the headwaters of the upper Colorado River are still rising, 26 as are Fontenelle and Big Sandy in the upper Green River Basin. However, total reservoir storage in the Gunnison and Green River watersheds is already at its lowest of the year. Total reservoir storage in the San Juan River watershed has been declining since mid-April but is not yet at its lowest point for the year.
OVERALL TRENDS IN BASIN STORAGE DEMONSTRATE RATCHET EFFECT IN FULL FORCE
In the context of the entire 21st century, Basin storage significantly dropped during two multi-year dry periods, 2000-2004 and 2020-2022 (Fig. 3).27 In other years, the bounty of snowmelt was temporarily stored but completely consumed in subsequent years. The resulting pattern for the 21st century is jagged, but the overall trend in storage has been relentlessly downward, because Basin average uses and losses have consistently exceeded average inflows. We call this pattern the Ratchet Effect, because a rachet is a mechanical device that only allows movement in one direction, in this case towards ever declining Basin storage and deeper into crisis.28 Despite laudable efforts to maintain balance through system conservation and assigned water programs, the ship continues to sink.

6 Live storage is all water stored in reservoirs that can be vacated by gravity, no matter how difficult or slow would be the process of withdrawing that water. Active storage is all water stored above minimum power pool, and inactive storage is water stored between dead pool and minimum power pool. These definitions differ from those used in previous papers that we have written. In past papers, we used the term active storage to refer to what we now refer to as live storage. This change is made to be consistent with terminology of Bureau of Reclamation.
7 We do not consider reservoirs that store Colorado River water but are located beyond the watershed boundary, such as Horsetooth or Twin Lakes Reservoirs in Colorado.
8 As discussed below, the March 2023 minimum was the lowest total Basin storage since May 1965 when the reservoirs of the Colorado River Storage Project were beginning to fill.
10 The total amount of water in the 46 reservoirs on August 24, 1999, was 59.52 maf. The only previous periods when total Basin storage exceeded that amount were for ~4.5 months between June 9 and October 24, 1983, and during parts of summer 1984, 1985, 1986, and 1998 The largest amount of live storage in these reservoirs was 63.61 maf on July 15, 1983.
11 Total live storage in Lake Mead and Lake Powell peaked at 47.70 maf on September 19, 1999, and was 13.38 maf on June 1, 2026.
12 The contents of these 12 reservoirs are reported in Reclamation’s 24-Month Study reports and include Taylor Park, Blue Mesa, Morrow Point, Crystal, Fontenelle, Flaming Gorge, Vallecito, and Navajo that are upstream from Lake Powell, as well as Lake Powell, Lake Mead, Lake Mohave, and Lake Havasu. The contents of the latter two reservoirs, as well as Morrow Point and Crystal, do not change much during the year.
15 The 12 federal reservoirs had 18.93 maf of active storage on March 14, 2023, and were at their lowest since early May 1965.
16 The largest single-year accumulation of Basin storage was in 2011, when storage increased 8.78 million af. Unregulated inflow in WY2011 was 15.97 maf, and natural flow in WY2011 was the largest of the 21st century (WY2011 = 20.16 million af). Unregulated inflow to Lake Powell in WY2023 was 13.42 million af, and natural flow of the Colorado River in WY2023 was 17.41 million af, the third largest of the 21st century.

June 4, 2026
As campers with boats flocked to Buckboard Marina at the start of Memorial Day weekend, Tony Valdez was busy issuing refunds and repairing broken boat ramps. One older Green River man, who walked with two canes, left with his money refunded for the season after discovering he could not safely make it down to the boat slip. Due to dropping water levels at Flaming Gorge Reservoir, the ramp is now buckled, angling up and down like a pitched roof.
“It’s devastating, not just to me, it’s all the marina owners,” said Valdez, who owns Buckboard Marina, south of Green River. “It’s a big loss, and this is a big loss to the community.”
Along the cliffs and shoreline, darker and lighter lines of rock and sand trace the water’s elevations, showing where the water hits when the marina is full, where it hovered this spring and where it dropped after an initial “flush.” Valdez estimates the reservoir has dropped by 7 feet since April.
But that’s not the worst of it. Valdez anticipates that by the end of this summer, the reservoir will be as low as it’s ever been.
Why the drain?
For all its charm as a beloved recreation spot and its utility as a local economic driver, Flaming Gorge Reservoir owes its existence to a legal compact that essentially regards it as an insurance policy in times of drought.
Its primary purpose, according to federal officials and Colorado River Compact scholars, is to serve as a backup water bank to help maintain the Colorado River system. Specifically, Flaming Gorge and a handful of other reservoirs in the upper Colorado River Basin states of Wyoming, Colorado, Utah and New Mexico are key to ensuring a minimum flow of 7.5 million acre-feet of water, on a running 10-year average, at Lees Ferry just downstream of Lake Powell, a massive man-made reservoir straddling the Utah-Arizona border.
Today, after more than 20 years of drought intensified by human-caused climate change, the Colorado River is in crisis, putting at risk massive agricultural irrigation operations that consume about 80% of its water. This past winter saw historically low snowpack in the Upper Colorado River Basin — a primary source for the river’s flow.

Combined with record heat in March, Lake Powell is at risk of dropping below Glen Canyon Dam’s “minimum power pool,” the point at which it can no longer produce hydroelectric power, according to water officials. If it falls even lower, the dam, which holds back Lake Powell, could be at risk of structural damage or unable to allow water to flow downstream.
The situation triggered a drought response operations agreement that calls for restricting releases from Lake Powell and an order to draw extra water from Flaming Gorge upstream. In total, water managers will release about 1 million additional acre-feet of water from Flaming Gorge in April 2026 through April 2027.
“These actions are expected to lower [Flaming Gorge’s] elevation by roughly 35 feet over the next year to approximately 59% of capacity,” the bureau said in April.
“The elevations are real critical,” Valdez said. At Buckboard Marina, high water has hovered between 6,030 and 6,040 feet above sea level over the past 50 years, he said. Dropping 35 feet could expose 400 feet of shoreline in some places, including marinas with boat ramps, he said.

If the water elevation continues to retreat, it could reach a point where boats can’t be brought in or out.
“By September, this thing is going to be down to 6,000 feet. That’s it,” Valdez said. “Next year, if it goes below that, there’s no more marina here.”
Setting a course
Water managers set a course in April to “stabilize” Flaming Gorge’s outflow to about 1,100 cubic feet per second, representing the rate needed to achieve the 1 million acre-feet of extra water release, according to the bureau. On top of that, there are two previously planned “flushes” from the Gorge. The first, in early May, temporarily increased the outflow to about 8,600 cubic feet per second to enhance the proliferation of razorback sucker larvae, and a second 72-hour flush beginning June 8 will temporarily increase the outflow to about 4,600 cubic feet per second to discourage the proliferation of smallmouth bass.
So far, Flaming Gorge has dropped from about 3 million acre-feet in April (or 82% capacity) to about 2.83 million acre-feet as of May 25. Meanwhile, water managers warn, “This release plan is subject to change depending on evolving river conditions and weather forecasts.”

Those evolving conditions include forecasted versus actual flows from streams feeding the system. For example, those “unregulated” or natural flows are forecasted to be much lower than normal: 70,000 acre-feet of water into Flaming Gorge during May (28% of average), 175,000 acre-feet in June (45% of average) and 84,000 acre-feet (42%), according to the Bureau of Reclamation.
Water officials caution that water flowing from the Flaming Gorge Dam could change, and that those recreating on the Green River below should monitor release schedules at this website. The bureau also noted, “Water will be colder than usual and will run high and swift during periods of elevated releases.”
Water floats recreation economy
Buckboard Marina went through a similar drop in water a few years ago. The Bureau of Reclamation began pulling water from the Flaming Gorge in 2021, and by 2022, the marina’s water level was at an all-time low. While the reservoir recovered somewhat in 2023 thanks to a good year for moisture, Valdez said, the reservoir has continued to decline since then.

Kokanee salmon and trophy-sized lake trout draw tens of thousands of visitors to Flaming Gorge each year, supporting a recreational economy in southwestern Wyoming and northeastern Utah. But as the lake is drawn down, water recedes from shallow shorelines and fish are forced into a smaller space, essentially shrinking the fishery toward the dam side of the reservoir.
One of Valdez’s primary concerns is that water levels could drop below the ideal elevation for kokanee to spawn in the reservoir.
“I think people don’t realize the economic value it brings,” he said. “It is a big deal when you lose your kokanees.”
Valdez has already lost money this year just from people being concerned about water levels. He estimated that the marina lost roughly $30,000 in cancellations when discussions about releasing water began as early as February.
Other problems also start to arise as the water drops. The marina will lose access to drinking water at 6,010 feet, below their floating pump that supplies potable water. It’s only 7 feet away from the current level.
“That’s scary to me,” Valdez said.
The marina can truck in water from Rock Springs, but it costs about $1,200 to bring in 8,000 gallons, which lasts about two weeks. For Valdez, it feels “asinine” to lose water at a marina.
“Why would we run out of water on a lake?”
Water levels also impact the location of the fuel dock and fuel lines extending to it. If the reservoir sinks too low, it could cost up to $100,000 to adapt, he said.
Drawing down water levels quickly — as happened in early May — can damage marina structures. After the 2021-22 drawdown, Valdez said he spent about $130,000 in repairs.

This time, he’d hoped to keep up. He and a group of 10 men worked to keep pace with the dropping water levels, repairing and modifying ramps. It wasn’t enough.
“The drop was dramatic enough to break all of our approaches, our bridges, our stuff, so it broke a lot of the welds, broke a lot of the structured steel, because it just vertically dropped too fast for the weight,” he said.
When structures go from water to land that quickly, the weight is too much for them to hold up, Valdez said.
“I’m re-rigging everything, and this is only a temporary fix ’til September, because that’s when the season ends.”
The marina should remain mostly functional until the summer season ends, he said. But with extra water releases set to continue through the winter, the lake could drop another 10 to 12 feet by the spring.
“We’re getting into numbers that I don’t even want to talk about,” Valdez said. “I mean, there’s no marina.”
What’s next?
“The guy with the boots on the ground that watches this every day,” as Valdez describes himself, can see what water managers can’t, and he questions whether official numbers and estimates match reality.
“It’s hard to watch this when it’s out of your hands.”
Valdez is critical of the 1922 compact, doubting the legal rationale of sending Wyoming water to places like Arizona. He also wonders about the role of local industries — refineries, coal-fired power plants and trona mines — that use large amounts of water, and the idea of adding more industrial facilities that require even more water, like data centers.
“We don’t have the water to give away,” Valdez said.

Bryan Seppie, general manager for the Joint Powers Water Board for Sweetwater County, Rock Springs and Green River, agrees. “The poor hydrology this past winter has affected most all water users in some form or another,” he said.
His board monitors the Colorado River system closely. Just upstream from Flaming Gorge, the Bureau of Reclamation reduced releases from Fontenelle Reservoir due to poor inflow projections. Although the water will still be enough for river users, the low summer flows will have a negative impact.
“Low river flows typically result in higher water temperatures, which generally leads to higher levels of moss/algae and overall lower water quality,” Seppie said in an email.
What about recovery?
Valdez wonders: What’s the plan to allow the reservoir to bounce back?
Wyoming State Engineer Brandon Gebhart and his staff have warned for months that although Flaming Gorge can serve as a backup to Lake Powell this year, it drains the Gorge’s ability to play a similar role next year, or the year after. It takes time for Mother Nature to replenish the bank.
“The big thing that nobody is talking about is the recovery,” Valdez said. “Where is the recovery of our water?”
This year’s drain on Flaming Gorge began at a low point. The reservoir hadn’t fully recovered after the last major pull. Rather than starting at a high point of 6,040 feet, the marina was at about 6,024 feet, he said.
“There’s no recovery plan,” he said. “We can’t just let them keep taking. I mean, where’s this end?”

If there is no grace period for the reservoir to replenish and officials want to take even more in the near future, starting from such a low elevation point, it will be “devastating,” Valdez said.
“The water going down is not the end of the world, it’s the recovery in a timely manner that really matters,” he said. “I can’t preach recovery enough.”
Watching people come to the marina and seeing how happy they are still motivates Valdez to keep going. Despite the drawdown, there’s nowhere else he’d rather be.
“We’re not going to run away. We’re not going to give up,” he said. “We’re going to fight.”

June 14, 2026
…it remains unclear whether Denver Water will ever be able to fill the reservoir to its new full capacity as a yearslong court battle lumbers on between the utility and environmentalists. Months of mediation between the parties have failed. Denver Water is now asking a federal appeals court to reverse a lower court judge’s 2025 order barring the utility from filling the expanded reservoir and ordering the yearslong federal permitting process to be redone. A panel of three judges for the 10th U.S. Circuit Court of Appeals is scheduled to hear arguments in the case on July 31 in Santa Fe…
U.S. District Court Judge Christine Arguello in 2024 found that federal regulators violated environmental protection laws when they failed to properly analyze the environmental impact of the project or consider reasonable alternatives to the dam expansion that would be less harmful. She later issued the order against filling the reservoir. Environmental groups argued in court, and in their filings, that regulators failed to evaluate how siphoning more water from the drought-stricken Colorado River would impact the basin as a whole. And the groups charged that they failed to weigh other project options that wouldn’t require the clear-cutting of a half-million trees or risk damage to wetlands. The case has drawn the attention of other Front Range water providers, lawyers from across the county and the U.S. Chamber of Commerce — all of which have filed briefs in the appeals case…
While the dam structure itself is complete, at least a year of work remains to fully finish the project, Martin said. Construction crews must finish the spillway and place the final topper foot of concrete on the completed dam structure. Divers will place a gate between the reservoir’s water and the dam’s intake tubes. But the crews on site will diminish in the coming months, from up to 500 workers a day to closer to 100. On the morning of June 3, crane operators already worked to remove from the dam crest the heavy machinery that was necessary to build the main structure.
Roller-compacted concrete will be placed on top of the existing dam to raise it to a new height of 471 feet. A total of 118 new steps will make up the new dam. Image credit: Denver Water.

May 7, 2026
Drought in Colorado isn’t abstract—it’s shaping decisions right now, from headwater streams to major reservoirs. And this year, the signals are hard to ignore. At the same time, conversations about water are tightening. There’s more concern and more sensitivity—especially around anything tied to water availability.
Snowpack across the Upper Basin has dropped to record or near-record lows. By early April, snow water equivalent in many areas fell to a fraction of normal, and snow cover reached the lowest levels observed in the satellite record. At the same time, this winter ranked among the warmest on record—reducing snow accumulation, accelerating melt, and increasing evaporative losses. These patterns are consistent with the impacts of climate change across the Colorado River Basin, where rising temperatures are diminishing snowpack reliability and reducing overall runoff efficiency.
June 1, 2026 seasonal water supply forecast summary.
Those conditions are now reflected in forecasts. Runoff across the Upper Basin watersheds is expected to be among the lowest on record, with sharply reduced inflows into Lake Powell. Meanwhile, Lake Powell and Lake Meadcontinue to sit near historic lows—leaving very little buffer in the system.
Even where spring storms have brought some relief, the underlying deficitremains. Dry soils, warm temperatures, and reduced snowpack mean less water ultimately reaches rivers.
This is not just a dry year. It’s a system under compounding stress.
Why This Matters: Ecological Drought
Ecological drought helps explain what those conditions mean on the ground.
That definition matters because it expands how we think about drought.
It’s not just about precipitation. It’s about how drought moves through a system:
From snowpack to soil moisture
From soil moisture to vegetation and habitat
From ecosystems to the services people depend on
Modern droughts are also changing. They are becoming hotter, longer, and more widespread, with impacts amplified by both climate conditions and human water use.
And those impacts don’t stay contained.
Ecological drought is fundamentally about connected systems. When ecosystems cross critical thresholds—losing wetland function, shifting vegetation, or degrading habitat—those changes feed back into water supply, with wide-ranging implications to agriculture, wildfire risk, and community stability.
What it Looks Like Right Now
In Colorado, ecological drought is showing up as a shift in timing, duration, and connectivity.
Even with recent moisture:
Peak river flows are shorter and less effective
River baseflows drop earlier
Floodplains connect less often
Wetlands and side channels dry sooner
These aren’t always dramatic changes—but they compound, especially when they occur in back-to-back years, reducing recovery time.
That’s a critical shift. Drought is no longer just episodic. It’s increasingly persistent, with ecosystems spending less time in recovery and more time under stress.
Birds Are Early Indicators
For birds, these shifts are immediate.
Migratory species depend on wetlands that function like stepping stones across the landscape. When those wetlands shrink or disappear earlier, habitat becomes compressed.
Riparian birds like the Northern Yellow Warbler and Song Sparrow rely on dense, water-supported vegetation during breeding season. Earlier drying reduces both cover and food availability.
And beneath all of this, food webs shift. Aquatic insects emerge differently under drier conditions, creating mismatches with nesting cycles.
Birds are often the first to show us what’s changing—but they’re not the only ones affected.
People Are In This System, Too
Ecological drought makes one thing clear: this is a single, connected system responding together. The same processes that shape habitat also shape outcomes for people. Soil moisture influences forage conditions for agriculture. Water timing and availability affect the reliability of community supplies. River flows support recreation and local economies, while connected floodplains help reduce risk and support recovery after disturbance.
This is what we mean by ecosystem services—the benefits people receive from functioning natural systems. When those systems are strained or begin to break down, those benefits decline as well.
What This Means for the Basin
The science is pointing to something bigger than a single dry year.
The Colorado River Basin is increasingly operating in a warmer, drier regime, where snowpack is less reliable and variability is higher. Recent conditions mirror some of the most consequential low-flow years in recent history—and they are becoming more frequent.
At the same time, current operating guidelines are set to expire, and the decisions made now will shape how the system responds to these conditions going forward.
What’s needed is a shift—from reactive, year-to-year crisis management to more durable and flexible operations; from short-term fixes to sustained investment in long-term resilience; and from fragmented efforts to stronger alignment across states, Tribes, and water users.
There is growing recognition that solutions must include conservation, efficiency, infrastructure, and watershed health—including restoration that improves how water is stored and functions across the landscape. Without that kind of alignment, risks will continue to compound—ecologically, economically, and socially.
A Clearer Lens for What’s Ahead
Ecological drought is not a new agenda. It’s a way to understand how drought actually works in today’s world—how water shortages move through ecosystems, how impacts cascade, and how those impacts ultimately reach people.
It connects snowpack to rivers, rivers to habitat, and habitat to communities. And it underscores something essential: when ecosystems are pushed beyond their limits, the consequences don’t stay ecological—they become systemic.
That’s why this matters now. Because the question in front of us isn’t just how we respond to this year’s drought. It’s whether we’re building a system that can function—ecologically and socially—under the conditions we know are coming (or are here).

In response to extreme drought conditions throughout northwestern Colorado, the Colorado River District, in partnership with the Colorado Water Conservation Board (CWCB), is offering up to 420 acre-feet of supplemental agricultural water from Elkhead Reservoir for irrigators in the Yampa River Valley. Modeled on the successful joint CWCB-River District program implemented in 2021, this effort will provide additional supplies during critical times of agricultural production.
“The drought conditions this year have been exceptional and unpredictable,” said Colorado River District’s Director of Asset Management, Hunter Causey. “And it’s that kind of unpredictability that hits small family farms and ranches the hardest. The Yampa Valley, the western slope, and our entire region depend on local agriculture to drive economies, produce local food, and preserve landscapes. While a program like this cannot solve the drought problem at large, we can be strategic in how we use our available supplies and support our constituents wherever possible.”
“The challenges posed by this year’s drought call for creative solutions and strong partnerships,” said Lauren Ris, CWCB Director. “This project reflects what can happen when local water users and water management agencies work together to respond to emerging needs. We’re pleased to support this collaborative effort in the Yampa Valley and remain committed to working with communities across Colorado to explore creative, locally driven solutions that help address drought impacts and strengthen drought resilience.”
Program Structure:
Water will be allocated using a lottery with an initial round of allocations of up to 50 AF per applicant, totaling 420 AF.
Any water remaining after the lottery will be awarded equally to initial round applicants that expressed a need beyond 50 AF. If there is any remaining water, it will be available on a first-come, first-served basis and will need to be contracted at no cost with the District.
Successful participants in the lottery will need to enter into a no-cost contract with the River District for direct delivery and/or use of the District’s Elkhead water through administrative exchange.
In the event there is a mainstem Yampa River call and to the extent that lessees are out-of-priority, water will be released at the diversion rate plus transit losses.
Water will be available for delivery or exchange beginning on July 10, 2026.
At current agricultural water marketing rates, the total project will cost $18,375. On June 4, the Colorado River District Board of Directors agreed to make $4,594 available from the Board’s previously authorized CFP expenditures for the District’s 2026 Drought relief effort. The CWCB has committed to providing the remainder of the funds – approximately $13,781.
Applications are due by June 26th, and a lottery will be conducted for the initial round of contracts on July 1st. Available augmentation water is limited. Those interested in applying should contact the Colorado River District’s Director of Asset Management, Hunter Causey, at hcausey@crwcd.org or visit HERE for more information.

Federal officials announced on Thursday that they plan on using a shorter-term framework for future Colorado River management so they can be more responsive to changing conditions and reservoir levels.
Acting Commissioner of the U.S. Bureau of Reclamation Scott Cameron said at an annual conference on water policy that the agency will be using a 10-year framework, issuing new operational guidelines every two years. In the absence of a seven-state deal for sharing shortages and managing reservoirs, river management now falls to the federal government — an outcome nearly everyone had hoped to avoid.
“We would love to have a 20-year deal or a 30-year deal but, frankly, we haven’t even been able to get the seven states to agree on what a two-year deal would look like,” Cameron said. “Given the highly unusual hydrological situation in the basin … we think it makes sense to take a second look at decision making every couple of years.”
As part of the required process under the National Environmental Policy Act, Cameron said Reclamation will release a final Environmental Impact Statement with its “preferred alternative,” in mid-to-late summer. It will lay out a more detailed 10-year operations plan for the nation’s two largest reservoirs, Lake Powell and Lake Mead, and will include short-term operational guidelines for 2027 and 2028. He said the plan provides a stable, transparent and adaptable framework for river management.

“We want to pay more attention to what’s actually happening in the river and what’s happening in terms of the elevation of the reservoirs,” Cameron said. “We want to manage conservatively during low inflow periods and hopefully be able to transition to recovery as conditions improve across the basin to keep the system stable and resilient.”
Cameron left the door open for a return to future management by the states and added that if they eventually come to an agreement, it could supplant the federal plan.
Cameron’s update came at the Colorado Law Conference on Natural Resources at the University of Colorado Boulder, hosted by the Getches-Wilkinson Center and the Water & Tribes Initiative. Water managers from around the basin gathered at the Wolf Law School in the midst of one of the worst droughts on record that threatens the water supply for about 40 million people in the American Southwest. Record hot temperatures and one of the worst snowpacks since measuring began resulted in streamflows that peaked much lower than normal and, in some reaches, a month early. Reclamation’s most recent projections put spring runoff into Lake Powell at just 800,000 acre-feet, which would be 13% percent of normal and the lowest on record.
On top of the abysmal hydrologic conditions, the basin is also in the midst of a management crisis. The Upper Basin states (Colorado, New Mexico, Utah and Wyoming) and Lower Basin states (California, Arizona and Nevada) after two years of negotiating have failed to reach a consensus on how they will share future cuts and have blown past deadlines to come up with a plan. The current guidelines, which have determined shortages and releases since 2007, expire at the end of the year. But for all intents and purposes, water managers need a new plan in place by the start of the new water year on Oct. 1.
Some of the problem still centers around the 1922 Colorado River Compact, which allocated half of the river’s flows (7.5 million acre-feet a year) to each basin. But this framework no longer applies under 21st century conditions, which has seen flows decline by 20% due to climate change. Despite indications a year ago that the states were moving to a supply-driven model based on each year’s snowpack and available water — rather than a fixed allocation of water — a new management framework the states can agree on has remained out of reach.

Beyond the band-aid
The feds’ operating plan for the first two years may be based on a proposal submitted by the Lower Basin states in early May, in which they propose to cut another 700,000 acre-feet of water per year through 2028, on top of the 1.5 million acre-feet they had already promised. California and Arizona will each take another 300,000 acre-feet of cuts and Nevada will take a cut of 100,000 acre-feet. The proposal does not include any mandatory conservation from the Upper Basin.
Federal officials responded in a May 28 letter with adjustments to make the proposal feasible, including the requirement that the Lower Basin states help pay for the 700,000 acre-feet of conservation. In the past, conservation programs have depended heavily on federal funding.
Becky Mitchell, who represents Colorado in the negotiations among the states, said during a Friday panel that the feds’ plan was a starting point but raises some concerns. Constantly renegotiating an operating plan every two years would be hard to fathom, she said.
“How do we fund and finance if we’re constantly renegotiating?” Mitchell said. “And how do we create the certainty that the 40 million people deserve?”
The feds have already stepped in this spring to prevent the worst consequences of the exceptionally dry winter and keep water levels at Lake Powell from falling below the threshold for making hydropower at Glen Canyon Dam. They are releasing up to 1 million acre-feet from Flaming Gorge Reservoir to prop up Powell and holding back Powell releases by about 1.5 million acre-feet. Cameron conceded, however, that these are temporary, stop-gap measures meant to address a critical situation.
“I think we succeeded in making everybody unhappy and everybody mad, which maybe means we’re doing the right thing in terms of Lake Powell,” Cameron said.
The Upper Basin states, including Colorado, are exploring ways to contribute water to a pool in Lake Powell as a means of maintaining higher water levels and an insurance policy against drastic cuts. But officials have not budged from their position that the Upper Basin is limited in what it can do and that cutting Lower Basin overuse is the primary solution to the Colorado River crisis.
Brad Udall, a water and climate scientist at Colorado State University whose presentation kicked off the conference, asked water managers not to waste this unique opportunity to redo 100 years of law and policy around how to manage a critical resource. And he directed a plea at the Upper Basin, saying that they, too, are part of the problem.
“We need everybody with a shoulder to this wheel,” Udall said. “We understand that the Upper Basin is different. We understand that they don’t have (large upstream) reservoirs and that every year people suffer. But we need you to help. Please help us.”

I’ve been on a “Colorado River sabbatical” of late, but I took a peek last week at Reclamation’s latest 24-month study. Holy moly things have gotten bad since the last time I looked!
Those not on sabbatical already know all of this, but to keep Lake Powell above a surface elevation of 3,500 feet, Reclamation is:
increasing releases out of Flaming Gorge on the Wyoming-Utah border
dropping releases out of Lake Powell to 6 million acre feet this year
Even with those two “hail Mary” moves, Lake Mead is projected in the “most probable” scenario to drop to elevation 1,020 by summer 2027. Under the “minimum probable” forecast, Mead drops all the way to elevation 1,008 in 2027.
We are on the brink, as a group of my colleagues explains in a new analysis out this morning (Monday June 1, 2026), of a system crash:
Even a wet year, my friends conclude, would only provide a short reprieve from the need to significantly reduce consumptive use.
Building on a similar analysis done last September (I was a co-author on that one), the authors attempt to overcome one of the shortcomings of the traditional Colorado River accounting systems, which is to treat any water above “dead pool” as usable storage. This is not the case, with clear do-not-cross lines in the reservoirs that are maintained for technical reasons well above the bottom, defined by my colleagues as…
One of the reasons for my “sabbatical” is, frankly, an agonized frustration with the abject failure of Colorado River governance at the basin scale, and a desire to turn my attention to the local level, which is where the problem solving responsibility seems to rest right now. Each community needs to be having a serious conversation right now about the specifics of its Colorado River water supply, and how it intends to go about using less. Blaming other people for using too much isn’t particularly useful at this point, we seem to have chosen to hand that set of questions (the rule-based part of “who is entitled to how much”) over to the courts, and who knows what that process holds. We know the answer for everyone is “use less water”, and each community needs to be getting on with that conversation.

This story is part of ongoing coverage of the Colorado River, produced by KUNC in Colorado and supported by the Walton Family Foundation. KUNC is solely responsible for its editorial coverage.
Water negotiators, river enthusiasts, Native tribes and lots of lawyers convened at the University of Colorado Law School on Thursday to take stock of the future of the dwindling Colorado River.
Here are five things KUNC’s water and environment reporter learned on the first day of the gathering.
There’s a thirst for treating the river as more than something to be consumed, and monetized and stretched out
Dale Sinquah, a tribal council member for Arizona’s Hopi tribe, is among a growing number of people who view the Colorado as a living being that should have the same rights as a person.
“If you look at it at that level and you allow it to, then it starts changing the ways in which you think about it, and maybe your actions,” he said.
Late last year, the Colorado River Indian Tribes of Arizona and California voted to give their namesake waterway the same legal rights as a person, saying the ‘living being’ deserves more protection while it’s being threatened by overuse and drought.
Sinquah said he had mixed reviews of the discussions at the water conference halfway through the first day.
“I’m kind of wondering if we’re stuck in that mode where you know personal interest (is winning) instead of how do we fix this as a whole, as a group,” he said. “It works better when you work together as a group.”
There’s still no finalized federal plan for the river yet, and the White House could have the final say…
Scott Cameron, the acting commissioner of the Bureau of Reclamation overseeing the operations of Lake Powell and Lake Mead, said the Interior Department is expecting to publish a short term operating plan for the reservoirs by “mid-summer.”
He said the plan would have to be renegotiated every two years and could be replaced at any time with one that the seven states can agree on.
“The good news is that the White House is very interested in what’s going on with the Colorado, so we’ll probably have to brief the White House on the (Secretary of the Interior’s) decision before it’s final,” Cameron said.

River negotiations are ongoing, but details are scarce…
First governors from all seven states in the river basin were summoned to Washington, DC, ahead of the Feb. 14 deal deadline they missed.
Then, after that didn’t work, came the Microsoft Teams meeting.
Scott Cameron, the acting commissioner of the Bureau of Reclamation, said Interior Secretary Doug Burgum recently talked with the seven governors again on the virtual meeting platform.
“The fact that he is trying to wrangle his gubernatorial colleagues twice, I think, indicates how seriously Secretary Burgum takes what’s happening in the Colorado River,” Cameron said.
However, no deal has yet to materialize as the states remain at an impasse, and some in the upper basin have called for a different mediator to intervene.

Forecasts for the river have gotten worse in recent months. And there was an acknowledgement that the status quo is not sustainable.

Could the feds get more involved in the management of upper basin reservoirs like Flaming Gorge? The answer is murky…
The audience asked Cameron, the Bureau of Reclamation official, about his thinking on how Interior should manage four large reservoirs in the upper basin that are collectively known as the upper initial units (they include Flaming Gorge on the Wyoming-Utah border).
Flaming Gorge is currently being partially drained so water can be sent down to Lake Powell so it doesn’t get so low that it stops producing hydropower.
Cameron said the Interior Secretary could exert more control over the reservoirs in the future in the event of an “emergency.”
“And what an emergency is, I think, is probably in the eyes of the beholder,” he said. “Now, you put four or five lawyers in a room. You’ll probably get nine answers on how much discretion the secretary has or doesn’t have in the upper initial units.”
Parts of the lake that have only recently been uncovered are full of old beer cans and other relics of boating escapades, including sunken boats.
But deeper down, Podmore shared photos of Native artifacts that have survived decades of being submerged.
New ecosystems are also taking shape.

June 7, 2026
Doug Kenney, principal organizer of annual gathering in Boulder, talks about how the growing tensions among basin states pose challenges in setting the agenda
The Colorado River has always had a magnetic appeal to the public consciousness. John Wesley Powell and his crew were instant national heroes after they emerged from the Grand Canyon in 1869.
That interest continues to this day. Bathtub rings are an absorbing visual, an easy way to communicate declines in the two biggest reservoirs in the basin, Mead and Powell. The river is being hammered by a warming climate and archaic governance of the shared resource.
This provides much to chew on, and that discussion continued again on June 4-5 at the Colorado River Conference hosted by the Getches-Wilkinson Center at the University of Colorado Law School. Organizers reported 373 people were registered to attend in person and another 132 remotely, a record for both. This surpasses a record set last year.
Afterward, Big Pivots sat down with Doug Kenney, the principal organizer of the conference, to take stock of what had just transpired. He directs the Western Water Policy Program and chairs the Colorado River Research Group.
What year did this conference begin? What was the thinking that gave birth to it?
I believe 1983 was the first one. This was mostly a creation of Larry MacDonnell, (the first director of the Natural Resources Law Center, a position he held from 1983 to 1994).
Larry pursued a dual mandate of researching key issues but also of trying to involve the public and other constituencies. A conference was a natural thing to do. We are an educational institution.
I’ve done the last 30 or so of them, but Larry got it started,
It seems like two or three, maybe three years ago, the tribes became a major presence in attendance and on the agenda. How did this come about?
Mostly through our professional networks. We knew people who were associated with the (Colorado River Basin) Water and Tribes Initiative. They wanted to broaden their reach and their influence. At the same time, we’ve here always wanted to involve tribal interests in what we do, going back to the work of David Getches and Charles Wilkinson.
We decided we’d try co-hosting a conference. It’s a partnership, and like all partnerships, it grows over time. But it’s working pretty well, I think.
Am I wrong? Was I missing something? I didn’t notice much of tribal presence in the agenda or participation until just a few years ago.
We’d usually maybe have one tribal speaker sprinkled in the program somewhere, but it was pretty hit and miss, in part I think because you kind of need a critical mass of involvement from the tribal community for other tribes to feel like this is a place that they’d be taken seriously and that they’d be welcomed. It wasn’t a slow linear growth to where we’re at today. There was a pretty dramatic shift four or five years ago.
How new is the Water Tribal Initiative?
They’ve been around I think for about a decade. They’re co-managed by Matt McKinney, who wasn’t here, and Daryl Vigil.

It’s not a national thing, but the Colorado Basin has 30 different tribes. That’s a pretty big number of tribes to keep track of. It’s a network as much as it is anything, and every so often they try to get together. They consider this conference their big convening. They also get to get together at CRWUA (Colorado River Water Users Association, which holds an annual conference during December in Las Vegas).
They have also produced a few research reports. This week they talked about their report on tribal sovereignty. And they have particular initiatives within the Water and Tribes Initiative, such as universal access to clean water. They are pushing, mostly through federal legislation, to provide assurances that all tribes have access to clean water.
Do they have a strong benefactor?
I don’t think so, but they have a very broad base of funders and supporters. A lot of water agencies, a lot of people, and a lot of organizations that know tribes have been treated poorly and that tribes have legitimate interests in the basin but (know) that many tribes just don’t have the resources to do this without some assistance.
As I’ve attended most years since 2002, I have noticed some ebbs and flows. There were some empty seats this afternoon, but the seats were mostly occupied through the first day and a half, and that’s somewhat different than, say, 10 years ago. What explains the ebb and flow?
I attribute that mostly to two things: one is this partnership with the Water and Tribes Initiative. The other thing is the fact that we’re talking about the Colorado River, which by every measure is in a crisis. It’s easier to get people’s attention when you’re talking about a crisis than when you’re talking about something that’s still not that serious. That’s part of it.
We used to be in another building. This is clearly a better facility for audience and speakers alike. That helps us attract a larger audience. We’ve had good foundation support, good funders. It takes a lot of money to do this, but we’ve had funders that see value in it. That has allowed us to make this a bigger event.
The conference is always the first week of June, so when do you begin rough-drafting the agenda?
Usually January. In some years it’s easier than others. This year was the most difficult. It was the easiest year in terms of attracting an audience. The hardest year in terms of putting the program together.
Everyone’s mad at each other, and everyone is — I can’t tell you all the back stories. Becky Mitchell said something today about how it’s hard to negotiate and prepare for litigation at the same time. She’s right. And I was thinking to myself, it’s hard to bring people together to talk at a conference while acknowledging the fact that they’re all mad at each other, and some of them are about to sue each other, and some can’t be in the same room with each other because they’re that angry, and some will be deeply offended if someone else is there.
It’s one of these years that there’s just so many delicate issues and angry folks — and angry for legitimate reasons; I’m not discounting that. But it’s been a really challenging year.
Your answer anticipates my next question, but I’ll ask it nonetheless. If memory serves me, a few years ago you had representatives of all seven basin states at the same table. This year you had two. I guess it’s fair to say that agenda setting has become more politically sensitive.
Every year for the last four or five years we’ve given all seven principals, all seven states, an opportunity to sit at the same table and have a discussion. In every passing year it becomes more difficult to do that.

You have seen this at CRWUA as well. Some years they had to divide into two sessions, upper and lower basin sessions. For awhile we were thinking of just having a lower basin session. The lower basin folks were happy to do that, but the upper basin folks weren’t as comfortable. We (also) thought about a different part of the session or a different location.
Ultimately we came to the conclusion that everyone could agree if it would be a conversation, not a posturing or confrontational thing. (Having) one upper basin person and one lower basin person, that was a format that could work. That’s what we did (with Becky Mitchell from Colorado and John Entsminger of Nevada). Anything more elaborate than that I don’t think was viable this year. It’s a really delicate time.
In terms of conferences devoted to the Colorado River do you have rivals for what you’re doing? Are there other places in Arizona or California, for example, that are kind of like must-go sessions?
There are two must-attend Colorado River conferences each year, and this is one of them. CRWUA (in Las Vegas) is the other one.
We specifically try to be different than CRWUA. We’re the opposite end of the calendar, roughly six months away. CRWUA is in many respects much more of a social event. We try to be more academic and about policy, with serious talk about serious issues. CRWUA, just like us, ebbs and flows from year to year in terms of what it looks like. But we try to be a little more hard-hitting and less of a, you know, take-the-family-and-have-a-vacation sort of event. I don’t mean to sound like I’m negative on CRWUA. I think we’re the perfect compliment.
Aside from that, there are some meetings such as CLE, Continuing Legal Education. It always has a Colorado River event. This year was quite good. Many other years, it’s not as strong. For practicing attorneys, that’s something that they want to go to every year, because they can get some credits there.
Still another one in New Mexico that’s held each year kind of commemorates the signing of the compact.
How do you measure success? I’m sure you constantly ask that question of yourself.
You understand the challenge of it all. We can measure success by the size of the crowd and that they mostly seemed to have a good time. In that sense, that’s success.
The other side of that is that we’ve been focused just on the Colorado River issues for the last five or six of these, and things have only gotten worse on the river. Obviously, we don’t think we’re to blame for that. But clearly, there’s no great success story that we can lay credit to either.
So I think we’re successful in that we promote conversation and the exchange of ideas, and we shine a light on new and innovative ideas, and we give a voice to people who sometimes don’t have a voice. This is where the tribes come into play again.
Some elements I think are successful, but in the very big scope of things, the issues that we’ve been addressing in our conference aren’t getting any better. It does force me to think about (and question) whether there is a better way for us to make a difference. I don’t know what that would be, but I do think about that a lot.

The Trump administration is attacking public lands again, this time in an apparent effort to open more special places to off-road vehicles. Late last Friday, Trump issued an executive order revoking a Nixon-era policy aimed at ensuring “that the use of off-road vehicles on public lands will be controlled and directed so as to protect the resources of those lands, to promote the safety of all users of those lands, and to minimize conflicts among the various uses of those lands.”
No, this does not mean unfettered swarms of ATVs will be kicking up dust on your favorite public lands next week. But it does bolster the off-road vehicle lobby’s effort to open up motorized access to federal lands, and takes away one of the long-term planning tools used by land management agencies to protect those places from off-road vehicle use and abuse.
In the nearer-term, Trump’s order could end or diminish the ban on OHVs in national parks, allowing the vehicles to travel backroads in, say, Capitol Reef National Park. This might not sound so bad: If a three-ton SUV can drive there, why not let a smaller side-by-side or four-wheeler on the same road?
The answer lies in the nature of the newer OHVs, namely “side-by-sides” or razors, which more closely resemble souped-up dune buggies than conventional SUVs. While some people use OHVs as mere modes of transportation, the vehicles are more commonly treated and utilized like recreational playthings — very powerful, fast, and noisy toys that tend to travel in herds. They therefore bring their own type of impacts.

Anyone who has traveled on or hiked around the Alpine Loop in the San Juan Mountains of southwestern Colorado on a busy summer day has likely experienced these particular impacts first-hand. Those roads were first opened up to OHVs in the early 2000s. Since then Alpine Loop traffic numbers have exploded, with at least half of the motorized traffic made up of OHVs.
Law enforcement officers now spend a disproportionate amount of time and energy trying to keep the OHV drivers on designated routes and in compliance with traffic laws. OHV crashes, often resulting in serious injury, are not uncommon. And each summer several riders surrender to the temptation to illegally leave the road — these are off-road vehicles, after all — and rip across the tundra, causing irreversible damage. Unlike regular vehicles, OHVs tend to travel in herds, spewing exhaust and kicking up dust, their collective buzzing reaching far beyond the roads on which they travel. It has become almost impossible during the high season to completely escape the incessant din of OHVs on the Alpine Loop, even in wilderness study areas.
This same phenomenon could now be coming to a national park near you.
The administration claims it eliminated the policy because it was outdated, vague, and redundant, because Congress has since passed a host of other laws protecting public lands from OHVs and other uses. The order goes on to say:
This makes very little sense. Sure, the restrictions on OHVs could hamper energy or timber development if it required destructive off-road vehicle use, but you’re not going to haul a drill rig into the backcountry on a side-by-side. And the idea that a hiker might feel “banned” from a trail because they couldn’t ride get there on an OHV is just silly.
The dubious statement reeks of the rhetoric of the crowd that claims that motorized vehicle restrictions are locking folks out of public lands, and therefore are discriminating against the type of people who drive these vehicles. But the discrimination claim simply does not fly. Mountain bikes are banned from wilderness areas, from a majority of trails in national parks, from some trails on BLM land, and are not allowed to ride off-trail on all federal land. This has nothing to do with the people who ride the bikes, or even the funny clothes they tend to wear, and everything to do with the vehicles’ potential impacts.
Trump probably did this at the behest of the Blue Ribbon Coalition and the likes of Sen. Mike Lee, who has pushed legislation that would open up national parks to OHVs. Maybe he’s trying to garner support from somewhere, given his terrible favorability ratings. Or perhaps he’s trying to appease the motorized crowd, which is probably a bit miffed that their drug of choice — gasoline — is so damned expensive thanks to Donny’s dumb war. Maybe he’s even trying to increase national park entry fee revenues so he can funnel it to his ballroom/drone-port or his White House UFC fight.

🐟 Colorado River Chronicles 💧
It pretty much goes without saying that if next winter is as bad as this past winter, in terms of mountain snowpack, then the collective users of the Colorado River and its infrastructure will be toast — at least figuratively (maybe literally, too?). Now, my favorite team of Colorado River wonks1 [Anne Castle, Jack Schmidt, Eric Kuhn, Kathryn Sorensen, Katherine Tara] have crunched the latest water numbers, and they’ve found that even a nearly “normal” winter won’t stop depletion of “reasonably accessible storage in Lake Powell and Lake Mead, leading to “devastating consequences.”
Back in 1999, the Colorado River’s storage system, which consists of Lake Powell, Lake Mead, and several other smaller reservoirs in the Upper and Lower basins, was almost full, holding about 60 million acre-feet of active, or available, storage. This provided a robust savings account that could be tapped during the inevitable dry spells on the notoriously fluctuating river system.
The reserve, however, was not adequate for the megadrought — or long-term aridification — that started in 2000 and continues today. Instead of following the usual up-down cycle, the Colorado River’s flows began a downward trend that is on track to hit its lowest point so far this water year, while consumptive use stayed more or less steady. Demand exceeded supply more years than not, drawing the savings account down significantly. That has forced the Bureau of Reclamation to take extraordinary measures, such as reducing downstream releases and tapping upstream reservoirs, to keep Lake Powell’s surface level from dropping below 3,500 feet, or what I call de facto dead pool 2.
Thanks in part to extra releases from Flaming Gorge Reservoir in May, Lake Powell’s surface level climbed slightly to 3,528 feet last month. Given that spring runoff in the Upper Basin has peaked and most tributary flows are decreasing, we can expect that number to start dropping, perhaps precipitously, at least until the monsoon arrives.
The wonks wanted an idea of how things might play out in the slightly longer-term, so they modeled two scenarios:
In the first scenario, they assume that the Colorado River’s natural flow, or the estimated amount of water in the river without human consumption or interference, will be similar to water year 2025, when the mountain snowpack was below average but not nearly as slim as this year. They also assume that consumptive uses will remain at the lowest levels in recent years.
Natural flow: 8.5 MAF at Lees Ferry + .70 MAF from Grand Canyon and Virgin River = 9.20 MAF Consumptive use: 3.56 MAF Upper Basin (includes evaporation and other losses) + 8.23 MAF Lower Basin + Mexico (incl. evap and other losses) = 11.79 MAF Deficit and resulting reservoir drawdown: 2.59 MAF Realistically accessible storage (RAS) remaining in Mead, Powell, and Flaming Gorge: 3.63 MAF
For the second, they plug in snowpack/flow numbers similar to those from water year 2023, which was a huge winter. Consumptive use would be about the same as in 2023.
Under the first scenario, the BoR will almost certainly have to go to a run-of-the-river situation on Glen Canyon Dam to defend 3,500 feet. That would mean releases would be approximately equal to inflows minus evaporation and seepage from the reservoir, and might drop to 3,000 to 4,000 cubic feet per-second or even lower. In the summer of 2002 inflows at times dropped below 1,000 cfs. This would turn the river through the Grand Canyon into a relative trickle, and cause a significant drawdown of Lake Mead.
The second scenario would be far better, but is far from an enduring solution. At best it would buy a little time, perhaps enough for the feds to build bypass tunnels around Glen Canyon Dam to allow for sustained releases below 3,500 feet. If it were followed by another three or four 2023-like winters, then things would start to look pretty darned good.
But if it were followed by just one more dry year it would bring everything back to today’s rather dire situation.
Since there’s no way to bolster supplies, the only way out of this mess is to continue to slash demand. The paper’s authors write:
Oof.
As long as we’re on the topic, the BoR recently released its Lower Basin accounting report for 2025, which tallies up consumptive uses in the basin. As you can see from the following graphs, which the Land Desk whipped up using the BoR data, the Lower Basin uses significantly less water now than it did in 1999, just before the current megadrought began. Upper Basin consumptive use figures for 2025 are not yet available. The following figures do not include reservoir evaporation, conveyance losses, or Mexico’s use.
All three Lower Basin states have substantially reduced Colorado River water consumption since 1999. However, more cuts will be needed if current climatic and streamflow trends continue. Data: USBR, Graphic: The Land Desk

Has Enchant Energy finally found a raison d’être? The Farmington-based company was created in 2019 to try to save the San Juan coal-fired power plant from retirement by retrofitting it with carbon capture equipment. Enchant would then sell the carbon to oil producers in the Permian Basin, while also receiving generous federal tax credits. Basically they wanted to turn the power plant into a taxpayer subsidized carbon dioxide factory. It flopped for various reasons. Now the San Juan plant — and all of its pollution — are no more. We suspected Enchant Energy had met a similar fate.
But then I received a press release letting me know the not-so-up upstart is not dead, but has instead signed a letter of intent with Creekstone Energy to capture carbon from the tech firm’s proposed hyperscale Delta Gigasite data center in Delta, Utah. As is often the case, Creekstone touts all of the renewable energy it plans on building for its center, but the first phase will be powered by natural gas, which emits carbon dioxide.
Enchant hopes to capture the carbon from the gas plant and convert it into marketable fuel. The company has apparently given up on trying to give coal-burning a slightly more climate-friendly veneer (after all, Trump has declared coal to be “clean” and “beautiful”). Instead, it looks like they’re jumping on the data center bandwagon, along with wannabe nuclear reactor developers and the like.
Who knows, maybe this is the thing that finally gives Enchant some meaning. But we’re not holding our breath. After spending gobs of money on lobbying, pulling in some hefty federal grants, then failing spectacularly with the San Juan generating bid, Enchant partnered with another firm and tried to buy the Intermountain coal plant in Delta to use it to power its own data center. That didn’t work, either.

🔋Notes from the Energy Transition 🔌
Yes, the energy transition may have run into some stumbling blocks, i.e. the Trump administration’s hatred for anything that might compete with coal and oil and gas, but it’s still quietly underway. For example, out by the aforementioned, defunct San Juan coal plant, DESRI recently broke ground on two utility-scale solar installations: the 170-megawatt Foxtail Flats solar-plus-battery storage array; and the 100-MW Four Mile Mesa solar-plus-storage project.
That’s some pretty serious generating capacity and adds to the existing San Juan solar facility nearby. Los Alamos County has signed on to purchase power from Foxtail Flats, and Meta will be drawing electricity Four Mile Mesa via PNM to power its data centers.
Both of the new facilities are under development on Ute Mountain Ute tribal land.

In last week’s comments, ncoffey94 asked what kind of bike I ride. It’s a 2023 Niner RLT, with an aluminum frame, carbon fork, and SRAM Apex parts. It’s nothing fancy and isn’t super light. But I dig it for riding on the roads, dirt, and even singletrack. It’s got 40 mm tires, so isn’t so great in the sand, and with no suspension I don’t do big drops or super-cobbly stuff. But it sure is nice having just one bike for all uses.

2 Water can no longer be released through the penstocks and hydropower turbine below 3,500 feet, forcing dam operators to rely on the lower river outlets for all downstream water releases. Those outlets are not engineered for sustained, long-term use, however, and could be damaged. The feared scenario looks kind of like this: The penstocks are closed; the river outlets release water faster than reservoir inflows; the reservoir surface level drops down to, say, 3,450 feet; the river outlets get damaged so must be shut down altogether, trapping the remaining water behind the dam and halting all releases until the water climbs back up to 3,500 feet. This would effectively dry up the Grand Canyon and cause Lake Mead to start plummeting as well. Of course, no one wants this to happen, so BoR is doing all it can to defend 3,500 feet, making that level the effective dead pool, even though technically 3,370 feet (the river outlet elevation) is the actual dead pool.

Poor soil moisture and snowpack conditions have led to well below normal April-May observed unregulated streamflow volumes, which are summarized in the below table.
Much of the CBRFC area experienced its warmest and least snowy winter on record. Following this, an unprecedented heatwave in March initiated significant snowmelt in areas that would usually still be building a snowpack. April brought cooler and wetter weather, and May generally continued this trend, with temperatures remaining mostly near normal across the CBRFC area. Portions of the GB and UCRB experienced periods of snowfall accumulation through May, but above normal precipitation was limited to small areas within the Green River Basin and Colorado River headwaters. In the LCRB, central/eastern AZ into western NM ended the month with significantly above normal precipitation, but this is a function of the very dry climatology as most of the LCRB routinely receives near zero precipitation in the month of May.
Water year 2026 precipitation summary.
Snowpack Conditions
Snow water equivalent (SWE) has been at or below record low for most of the snow accumulation season. The significant heatwave during the last half of March led to historically low April 1 snow water equivalent conditions across the region. UCRB and GB SNOTEL SWE peaked around March 8, which is 3-4 weeks earlier than the 1991-2020 normal peak date. June 1 SWE across the UCRB and GB is generally less than 25% of normal, with more favorable conditions in the Upper Green River Basin. SWE conditions are summarized in the figures and table below.

Soil Moisture
CBRFC hydrologic model soil moisture conditions impact water supply forecasts. Basins with above average soil moisture conditions can be expected to experience more efficient runoff from rainfall or snowmelt while basins with below average soil moisture conditions can be expected to have lower runoff efficiency until soil moisture deficits are fulfilled. The timing and magnitude of spring runoff is impacted by snowpack conditions, spring weather, and soil moisture conditions.
Mid-November 2025 soil moisture conditions were below average across most areas as a result of warmer and drier than normal weather during the 2025 water year. Early June soil moisture conditions are generally well below average across the region due to the lack of snow. CBRFC hydrologic model soil moisture conditions are shown in the figures below.

Upcoming Weather
Temperatures are heating up across the CBRFC area as June begins. Precipitation chances in the near-term are limited to warm, convective showers and storms, mainly over eastern areas. The 7-day precipitation forecast and the Climate Prediction Center (CPC) 8–14 day temperature and precipitation outlooks are shown in the figures below.

In a brief order Tuesday, the court accepted the recommendation of a special master to move forward with agreements first proposed last year by New Mexico, Texas and Colorado. The settlement calls for reducing groundwater pumping along the dwindling river and retiring water rights from irrigated farmland in southern New Mexico. The states held up the proposal as a promise to restore order to an elaborate system of storing and sharing water between two vast irrigation districts in southern New Mexico and western Texas.
“We’re very excited to be redirecting resources from costly and lengthy litigation to solutions on the ground,” Hanna Riseley-White, director of the Interstate Stream Commission, said Wednesday…
Those solutions will include everything from long-term fallowing programs and more efficient irrigation infrastructure to developing new sources of water, like tapping brackish supplies or importing water, and improving stormwater management so more runoff can be captured and stored.
