October 8, 2026

The Upper Gunnison River Water Conservancy District Board of Directors approved lowering the Oct. 31 reservoir level at Taylor Reservoir from 50,000 acre-feet to 48,000 acre-feet at its Sept. 28 meeting. The targeted Oct. 31 water level helps guide releases from the reservoir into the Taylor River downstream, since the level determines how much water is available for release. It also affects how much the reservoir refills over the winter and how much water is available for release the following year. Decisions on reservoir levels and releases are guided by the Taylor Local Users Group, which includes representatives for a variety of recreation interests on the river, irrigators on the Taylor and Gunnison rivers and property owners in the area. Taylor Local Users Group recommendations on releases and reservoir levels must then be approved by the Upper Gunnison River Water Conservancy District, the Uncompahgre Valley Water Users Association, the U.S. Bureau of Reclamation, and the Colorado River Water Conservation District, all of which are signatories to the 1975 agreement that established rules governing the reservoirโ€™s operations…

At the Sept. 28 Upper Gunnison River Water Conservancy District meeting, Don Sabrowski, district president and Taylor Local Users Group chair, explained that, since 2026 is a dry year, the target for the Taylor Reservoir was not to go below 50,000 acre-feet by Oct. 31. According to Upper Gunnison River Water Conservancy District General Manager Sonja Chavez, the district usually aims to keep the reservoir from dropping below 70,000 acre-feet in normal or wet years.

October 14, 2026

During a meeting held by the Archuleta County Board of Health (BoH) on Sept. 17, the board heard from Water Quality Manager Jessica Green about potential changes to the countyโ€™s regulations involving on-site wastewater treatment systems (OWTS). Green commented that the OWTS program โ€œhas been pretty overwhelmingโ€ for staff since the beginning of the year…Green explained that the inspection ensures the condition of the system is evaluated at the point of a property title being transferred, โ€œwhich prevents failing systems from being sold without disclosure of risk.โ€

She also explained that it provides oversight with higher-risk properties through existing exemptions, adding that the state does not define what exemptions are possible and that the county can adjust those exemptions to meet its needs…Green โ€œstronglyโ€ recommended that the BoH keep the transfer-of-title program, noting that there is a $115 permit cost associated with the program. She added that if the BoH chooses not to keep the program, there would be a risk that failing systems could be transferred to new property owners without knowing there is an issue.

Here’s the release from Governor Hobbs’ website:

October 16, 2026

Today, Governor Katie Hobbs and the Arizona Department of Water Resources (ADWR) announced the State of Arizona has intervened in a lawsuit brought by Nevada against the Department of the Interior to hold the federal government accountable for failing to enforce Upper Basin water delivery obligations to Lake Mead and prevent cuts of up to 3 million acre-feet per year. In joining this lawsuit, the State will seek to preserve the two-year Lower Basin Agreement while ensuring the federal government is delivering the water to Lake Mead that belongs to Arizona and the Lower Basin states.

โ€œArizona has always been willing to do our part to protect the Colorado River, but we will not accept a forced federal plan that solves this crisis on the backs of our families, farmers, and businesses,” said Governor Katie Hobbs. “We are drawing a line in the sand. I am taking this legal action alongside Nevada because the federal government refuses to hold the Upper Basin accountable for the water deliveries they owe Arizona, and is threatening to force draconian cuts that go well beyond the Lower Basin Agreement. While we ensure our voice is heard in court, weโ€™ll continue working alongside Nevada and California to implement the Lower Basin Agreement and prevent a devastating cut to Arizonaโ€™s Colorado River water.โ€

โ€œIntervention in the Nevada lawsuit is necessary at this time for Arizona to protect its legal rights to Colorado River water while preserving a path forward to achieving a collaborative outcome with California and Nevada to protect the Colorado River system,โ€ said ADWR Director Tom Buschatzke.

The Lower Basin Agreement is an agreement between Arizona, California and Nevada to protect the future of the Colorado River and prevent forced federal cuts that would slash the Central Arizona Projectโ€™s Colorado River allocation by 77% over the next two years. In the Agreement, Lower Basin states commit to conserve over 3.2 million acre-feet in 2027 and 2028 to stabilize the Colorado River system. Finalizing the Lower Basin Agreement remains a priority for the State of Arizona.

Joining this lawsuit ensures that Arizona can protect the Stateโ€™s interests in any legal outcome and challenge elements of the federal Final Environmental Impact Statement and Record of Decision that unlawfully fail to require deliveries from Upper Basin water reservoirs to Lake Mead. These federal decisions could result in 3 million acre-feet per year in cuts to the Lower Basin states, inflicting devastating water reductions while the Upper Basin States avoid any required conservation.

[ed. The “required conservation” argument is pipe dream. Buschatzke is fixated on the impossible because the Lower Basin has had certainty of deliveries since Hoover dam first filled, while no Upper Basin diverter has ever had that kind of certainty. He fails to acknowledge the difference between mountain rivers, with hundreds of diversions, where most of the water comes from, and desert rivers where there is little precipitation adding to streamflow. The Colorado Division of Water Resources cannot legally force diverters to bypass water and they do not have the ability to shepherd the water to Lake Powell. It is not possible to accurately measure conserved water at this time (apologies to Dr. Parshall). I think the Lower Basin legal position is very strong and they will press the advantage in court which will take a long time to resolve. Meanwhile available water continues to decline and the LB won’t come to the table to negotiate “wet water” vs. “paper water”. The combination of Climate Change and the “Law of the River” drained Mead and Powell, not Upper Basin consumptive use.]

The Colorado River Basin spans seven U.S. states and part of Mexico. 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)

Aurora tests the waters of #Coloradoโ€™s new wetland protection rules — Jerd Smith (Fresh Water News)

October 15, 2026

Auroraโ€™s proposed Wild Horse Reservoir project, southwest of Denver in Park County, is drawing close scrutiny this fall as it undergoes review under a new state law designed to protect critical wetlands and streams no longer shielded by the federal Clean Water Act.

According to the Colorado Department of Public Health and Environment, Wild Horse represents the first major project to be reviewed under Coloradoโ€™s new hard-fought wetland regulations approved in December. They are meant to replace federal rules wiped out by a U.S. Supreme Court case in 2023, Sackett v. EPA, and subsequent actions by the EPA. The CDPHE is responsible for enforcing the new regulation.

Colorado is one of the only states that has succeeded in crafting new rules. That work comes as the federal government continues to narrow protection of wetlands once provided by the Clean Water Act.

โ€œAs the federal government continues to roll back [protections], Colorado is going to need to step up. This is an incredibly important milestone for Colorado. All eyes are on this application,โ€ said Sabrina King, water campaign manager for Conservation Colorado, one of the environmental groups that helped craft the bipartisan measure ultimately approved by Colorado lawmakers last year.

The $600 million-plus Wild Horse Reservoir project would store 93,000 acre-feet of water and will be nearly twice the size of the cityโ€™s existing Park County storage pond, Spinney Mountain Reservoir, which holds 53,651 acre-feet of water. An acre-foot equals nearly 326,000 gallons of water, enough to serve at least two to four urban households for one year.

The proposed reservoir is among the latest moves by the city to secure future water supplies to meet growth-driven demand as streams and rivers shrink because of climate change.

Aurora Water officials say the reservoir is critical to providing a storage pool closer to the city and that it wonโ€™t involve taking additional water supplies from its water in the Eagle River and Homestake Creek. Instead, they say the reservoir will store water they now hold in nearby Spinney Mountain Reservoir, freeing up space to store water it currently owns and uses, but which it doesnโ€™t always have the room to store.

Some of that newly accessible water will be used to help expand Auroraโ€™s large-scale recycled water program, according to spokesman Zachary Henry, helping fulfill its promises to reduce water use even as it expands its collection system.

Still, powerful Western Slope water agencies, including the Colorado River District and the Eagle River Water and Sanitation District, and environmental advocacy group Save The Colorado, have expressed concerns about the proposed reservoir and its impact on the stateโ€™s drought-stressed water supplies.

โ€œThere is a question if this project involves additional new diversions or are they just moving water that they were already storing and moving in the Homestake Valley,โ€ said Gary Wockner, president of Save The Colorado. โ€œAurora appears to be claiming that this doesnโ€™t involve new diversion of water, but it is not clear. โ€ฆ The public needs to know.โ€

Due to these concerns and those of other interested parties, the CDPHE agreed to extend the public comment period to Nov. 19 to give more time for the application to be examined, according to CDPHE spokesperson Kaitlyn Beekman.

Under the new rules, regulators have roughly two years to complete the review process. Aurora officials said they expect construction to take five to six years and that the reservoir is likely to take five to 10 years to fill as climate change continues to shrink streamflows.

Key Points

  • The CAP board authorized legal action “if necessary” against the Interior Department over its plan to manage shortages on the Colorado River.
  • Nevada has already sued the feds over the plan, claiming that it violates the Colorado River Compact and would devastate the Las Vegas economy.
  • Arizona lawmakers have set aside money and hired a law firm to sue the federal government, but have not acted yet.

The Central Arizona Projectโ€™s board authorized its legal counsel to take legal action โ€œif necessaryโ€ against a federal plan to cut Arizonaโ€™s share of Colorado River water dramatically in coming years. Board members went into a closed executive session before the Sept. 3 vote to discuss certain โ€œoccurrencesโ€ that could trigger a lawsuit or other legal filing, and did not specify them when voting unanimously for the authorization. Board member Alexandra Arboleda introduced the motion at the meeting and prefaced it with a statement that the United States Department of the Interior’s 10-year framework for dealing with water shortage โ€œcontemplates operations that are contrary to law and devastating to the water users of the Central Arizona Project.โ€

#Aurora Water set to buy up more historic farm water in Lower Arkansas Valley — Michael Booth (Fresh Water News) #ArkansasRiver

Click the link to read the article on the Water Education Colorado website (Michael Booth):

September 9, 2026

Aurora Water is in talks to purchase land and water from two of the most historic farms in the Lower Arkansas Valley, adding to farm communitiesโ€™ worries about โ€œbuy and dryโ€ pressure from cities amid historic drought and a dwindling agricultural economy.

But Aurora Water says it has learned lessons from past controversies and is structuring the latest buy-up to preserve southeastern Colorado farm life, not destroy it. Though Aurora Water and the farms say they are in nondisclosure agreements and canโ€™t name the specific sites, Aurora says it wants the contracts to allow the farms to keep some working water every year.

โ€œThe farms that have the backing of a city . . . they may be the last farm standing because we have taken a lot of the risk away, or we will be taking risk away that the farmers currently have to struggle with on their own,โ€ said Alex Davis, Aurora Waterโ€™s assistant manager for supply.

โ€œI hope that people see the value of what weโ€™re trying to do, and they see that we are really trying to share water with agriculture in a way that allows the city to thrive, and the local community and the agriculture to thrive,โ€ Davis said. โ€œThatโ€™s a tough nut to crack, but we think weโ€™re doing it.โ€

Recent southeastern Colorado water purchases by Aurora Water and other utilities have given the agencies rights to dry up farmland in, for example, three out of 10 years. Many local farmers and water conservancy officials say that casts too much uncertainty on a farm ownerโ€™s economic plans. They are also not convinced that farmland can recover after being completely dried up for entire seasons.

Aurora Water says the deals it is negotiating now would be more like taking roughly 30% of the water in a given year, leaving the rest for the family farming to continue every year. That would fallow a similar portion of land to what southeastern farmers already fallow in crop rotations, Davis said. Aurora Water would buy the land and the water rights, and then lease both back to the existing family farm to operate.

Lower Arkansas Valley officials want to see details of Aurora Waterโ€™s agreements before judging whether the suburban utility is actually partnering with local farmers, or simply patronizing rural communities in new ways.

โ€œUltimately, it is up to individual landowners to decide what is best for their farms and their families. At the same time, this situation highlights a much larger issue for Colorado. Farmers need viable alternatives to selling their agricultural water to municipalities as they make decisions about the future of their farms and water rights,โ€ said Jack Goble, general manager of the Lower Arkansas Valley Water Conservancy District.

The district and other southeast Colorado leaders have challenged past farm purchases by Aurora and Colorado Springs as a threat to the local culture and economy. They have demanded that cities and suburbs conserve more water before building more homes, and commit to preserving rural farming and tax bases when making water deals.

โ€œIf we want irrigated farming to remain a meaningful part of Coloradoโ€™s future, we need policies and conservation tools that allow farmers to benefit from the value of their water while supporting the agricultural economy and communities that depend on it,โ€ Goble said.

Aurora Water says it has agreed to make โ€œpayments in lieu of taxesโ€ to keep local communities financially whole in past agreements, and plans to with the new buy-ups as well.

Water officials in southeastern Colorado say they know which historic farms, operating for more than 100 years, are talking with Aurora Water this time around, but did not name them out of respect for the families and the nondisclosure agreements that usually accompany such negotiations.

Eric Hanagan, the family leader of Hanagan Farms in Swink that produces melons, chiles and other produce, said the farm is part of a non-disclosure agreement but did not identify the parties.

When told Aurora Water had said it was negotiating water rights deals that would allow longtime family farms to keep operating, Hanagan said, โ€œWell, itโ€™s important to us, and I think thatโ€™s why we have kind of pursued this, an interest in this path.โ€

Aurora Water says even if it finishes acquisition of additional land and accompanying water rights this year, it will abide by past intergovernmental agreements that say no more than 30,000 acre-feet of water will be taken out of Lower Arkansas farmland each year. The current negotiations with the family farms involve smaller amounts of water than a controversial 2024 agreement Aurora Water made.

That year, Aurora spent $80 million to buy nearly 5,000 acres of farms in Otero County and the more than 6,500 acre-feet of water associated with the land. An acre-foot equals nearly 326,000 gallons of water, enough to irrigate half an acre of corn, or supply at least two urban homes for one year.

Aurora plans to use that water itself in three out of 10 years, leaving it on the farms the rest of the time. Some 4,000 acres of land will be dried up intermittently when Aurora is using the water, according to those who helped negotiate the pact.

Data shows Coloradoโ€™s irrigated farmlands are shrinking. Since 1997, the state has lost 32% of these lands, with areas in the Lower Arkansas Valley seeing losses higher than that, according to an analysis of federal agricultural data by Fresh Water News and The Colorado Sun. Crowley County lost 90% of its irrigated lands in that period. Pueblo has lost 60.2%, and Bent and Otero have lost 37.6% and 35.2%, respectively.

In addition to losing farm tradition, agriculture jobs and tax base for local governments, the transfers of water to cities and suburbs in past decades left dried-up lands unplanted and unreclaimed. Colorado Springs and Aurora have agreed that decades-ago buy-ups were not handled properly, and they claim more recent agreements and a new state law include requirements for reseeding with native grasses and protections against erosion and decline.

Current water purchase negotiations are more realistic, Davis said, about how much of their water the farmers are using in a given year, and how much land is fallowed and goes unirrigated because of longer-term agricultural needs. Alfalfa, a very thirsty crop, is one example, she said. One planting of alfalfa can be harvested for five or more years, but then those fields need to lie fallow for a time before new alfalfa seed is planted.

โ€œI think what a lot of farmers have realized, who would like to participate in the type of deal that weโ€™re structuring here, is that all farmland eventually needs to be fallowed in order to keep the land healthy,โ€ Davis said. โ€œAnd so if you can have a rotational fallowing schedule that allows portions of the farm to be fallowed on a regular basis, and thatโ€™s the water that is moved to the cities, that works better for the farmers, and it works better for the cities.โ€

Any upcoming deals would not be a strict โ€œ30% a yearโ€ formula, Davis added.

โ€œSome years, you might only fallow 10% of the farm, 10% of the water. Some years you might move 35% or 40% of the water, and it would be kind of balancing water availability with best farming practices,โ€ Davis said. โ€œWeโ€™re looking to prove that a city can really share water with farming operations and keep farms viable.โ€

From email from ADWR:

October 16, 2026

Today the State of Arizona filed a motion to intervene in the Nevada lawsuit challenging the recent federal decision governing the operation of the Colorado River.

Like Nevada, Arizona believes the federal governmentโ€™s new operating framework ignores basic elements of the Law of the River and could result in cuts to the stateโ€™s apportionment that would devastate Arizonaโ€™s economy.

These elements go far beyond and fall outside the Lower Basin Agreement to which we are strongly committed and continue to work with Nevada and California to implement.

Our problems with the federal governmentโ€™s Record of Decision are twofold.

One: the federal governmentโ€™s plan fails to deliver the water that Arizona and our fellow Lower Basin states are owed according to the Law of the River.

Two: the federal governmentโ€™s Year 3-10 plan includes a range of โ€œsideboardsโ€ that, if triggered, could require reductions to the Lower Basin of up to 3 million acre-feet per year in priority. Such reductions could effectively dry up the Central Arizona Project canal system, as well as many of our on-river communities and would more than double the water cuts agreed to in the Lower Basin Agreement.

Arizona believes that taking this action now provides the best path forward for protecting Arizona water users. We are confident that our negotiations with California, Nevada and the U.S. will move forward. In fact, by taking this step we are protecting the integrity of our Agreement. By joining this litigation we can protect Arizonaโ€™s interests, whether thatโ€™s before a judge or in any settlement discussions that may ensue.

Arizonaโ€™s priority remains the completion of a Lower Basin Agreement with California, Nevada, and the U.S. to share in water reductions over the next two years and to memorialize the Intentionally Created Surplus tool. Through our participation in this litigation we will seek to assure that the agreement is implemented.

The Lower Basin states have contributed millions of acre-feet of water toward stabilizing the river system. With more than 5.5 million acre-feet of Arizona water left in Lake Mead since 2014, no state has sacrificed more. In collaboration with our Lower Basin state partners, the Lower Basin Agreement demonstrates that we are doing more. But the US decision puts the entire burden of sacrifice on the shoulders of three states. We are joining Nevada in challenging that framework.

#HalliganReservoir Water Supply Project Update: City of Fort Collins seeks to join Northern Integrated Supply Project #NISP #PoudreRiver #SouthPlatteRiver

The Northern Integrated Supply Project, currently estimated at $2 billion, would create two new reservoirs and a system of pipelines to capture more drinking water for 15 community water suppliers. An environmental group is now suing the Army Corps of Engineers over a key permit for Northern Waterโ€™s proposal. (Save the Poudre lawsuit, from Northern Water project pages)

From email from the City of Fort Collins:

October 15, 2026

For decades, the City of Fort Collins has been working on the Halligan Project to provide water storage to meet Fort Collins Utilitiesโ€™ customer demands into the future and provide drought security and resilience. The U.S. Army Corps of Engineers has not yet issued the final permit, and it has become increasingly doubtful the agency will issue an approval. Meanwhile, rising construction and permitting costs have made it increasingly difficult financially. Given these circumstances, the City had a responsibility to investigate other options.

On Oct. 20, City staff will present factors driving a recommendation to City Council to pivot to a different water storage project. Discussion points will include Halligan Project permitting challenges, water storage needs, financial impact analyses, environmental considerations, and overall recommendations to City Council. The City Council materials and agenda will be posted by end-of-business on Oct. 15 at this link.

The City plans to host an informational meeting so community members have a chance to learn what’s next and ask questions. When the date is finalized, we will send another email with the details.

October 13, 2026

This will be my last post before what might be our last election โ€“ if our would-be tyrant doesnโ€™t succeed in stopping it entirely. I encourage my handful of readers to vote early, and then be prepared to participate in public opposition โ€“ make a big noise โ€“ to the chaos our PINO will surely try to cause if he doesnโ€™t like the outcomes.

The mainstream media (being mostly owned by billionaires) continue to try to portray this election as just another horse-race between โ€˜Democrats and Republicans.โ€™ It is not that. This election may be out last chance to salvage what the Trumpsters havenโ€™t yet undermined of our 250-year effort to work out a functional governance by, for and of the people โ€“ a representational governance, a form of democracy. At present nearly all of our supposed representatives in Congress who call themselves โ€˜Republicansโ€™ and many of those who call themselves โ€˜Democratsโ€™ are clearly โ€˜ownedโ€™ by those with the money to fund their campaigns โ€“ the oligarchs and kleptocrats who want to replace that 250-year effort with an authoritarian governance that they believe will be more โ€˜efficientโ€™ in accommodating them.

The only hope for keeping our 250-year experiment in self-governance going is to replace the sellouts with representation in the mold of Bernie Sanders, Elizabeth Warren, Alexandria Octavio-Cortez and others who truly try to speak and act on behalf of us, rather than of those whom we have all helped make morbidly wealthy. And we will only be successful if it is a decisive victory for the people; one or two percent victories will be challenged and kept in chaos until โ€“ well, forever: nearly a third of the voting electorate still believe that Trump was cheated out of a 2020 election victory because Trump says so. He is determined to keep this election from being a conclusive victory against him because he knows that the only way to stay out of prison is to stay in the presidency with a compliant Congress.

So vote as if the future depended on it โ€“ because it does. We do not want to live in an oligarchic kleptocracy run by a semi-senile narcissist with his gang of thieves pillaging the people to pay for technologies of mass control, with his army of brownshirt ICE agents running rampant in our streets. If we donโ€™t come out of the election with a Congress at least partially in control of representatives of the people (not just โ€˜Democratsโ€™ โ€“ think of Fetterman), then it is all over.

Meanwhile, back on the banks of the bankrupt Colorado River system. Remembering first that the river system is not the river itself. The river itself is what it has always been: flows of water running through river-carved valleys and canyons because the surrounding land has not put those flows to use in service to living things. The flows move on to other valleys where sometimes they are put to use by plants, forests, wildlife including humans, and sometimes not, then flowing on to other valleys until they all eventually join up and get to sea level, reentering the seas from which they came. Those flows ebb and flow themselves, annually and year-to-year, at the whims of the global climate โ€“ which at this point has the human thumb on the scales pushing toward the hotter drier side.

Thatโ€™s the river; the river system is the structures for storage and distribution we have imposed over the river to even out the natural flows, annually and year-to-year, in service to human life. But the system was designed for a river half again larger than the river weโ€™ve had since the turn of the century; it is beyond rational denial that it was overbuilt for the river we now have (see the graph above), although many continue to deny it for reasons including plain desperation.

That suggestion will come in time, but first I think we need to define the current reality (which bears no resemblance to โ€˜Compact realityโ€™). The first step is to acknowledge the nature of a desert river, then try to adapt our basic thinking and planning to that.

All rivers are water that the surrounding land and its diverse inhabitants have not managed to put to โ€˜beneficial useโ€™ for the living ecologies the river runs through. That โ€˜left-overโ€™ water flows on from its home watershed to larger multiple watersheds where it either gets put to use or doesnโ€™t, and if not, it flows on even larger basins, et cetera. Hydrologists describe streams as โ€˜gainingโ€™ or โ€˜losingโ€™: a stream that adds surface and groundwater from a watershed with a high water table is a โ€˜gaining streamโ€™; a stream that gives up some of it water to a watershed with a lower water table is a โ€˜losing streamโ€™ (although I think it ought to be called a โ€˜giving streamโ€™).

Many humid-region rivers continue to collect more water from precipitation that falls on them and their surrounding land, from its headwaters all the way to its ocean estuary. A desert river, on the other hand, gets nearly all the water it will ever have from its headwaters region, with mountains or plateaus high enough to force rising air to cool and release any water vapor it carries as precipitation โ€“ mostly winter snow in the case of the Colorado River. Most of the Colorado River headwaters are in the Southern Rockies, but the Wind River Mountains in the Central Rockies generate some of the Green River tributaries, the Colorado Plateau and New Mexico highlands generate the Gila River; smaller basin-and-range mountains the Virgin River, et cetera. But the precipitation that falls on those high places generates 85-90 percent of the water that will make its way into the Colorado River; once it leaves its headwaters and flows into its desert regions, it will gain very little new precipitation.

This transition from gaining streams to losing (giving) streams happens fairly quickly in the Colorado Riverโ€™s natural basin. The majority of its water comes from highlands above ~8,000 feet elevation โ€“ about ten percent of the entire basin. In the Upper Gunnison River watersheds where I live, major Gunnison River tributaries leave the Crested Butte area at 9,000 feet elevation where the average annual precipitation is 23 inches (up to 40+ inches on upvalley); a mere 35 miles down the valley in Blue Mesa Reservoir, at 7,500 feet elevation, the average precipitation has dropped to 10-11 inches. In that short distance, the Gunnison River is already in the high deserts of the Colorado Plateau, and most of the valley below Crested Butte is under irrigation โ€“ the river already โ€˜giving.โ€™. The Gunnison River gets larger as it flows west and north to its โ€˜grand junctionโ€™ with the Colorado River, but that is due to picking up other tributaries; very little precipitation water gets added โ€“ even in the summer monsoons, according to a hydrologist working in the Upper Gunnison.

Prior to the Euro-American presence in the basin, the Colorado River ran in extremes: a flood of water while the snowpack was melting in the high headwaters, then a comparative trickle in the late summer and fall after the snowmelt ends. The flood months nurtured riparian life throughout its course, from a narrow strip in some places to broad wetlands, meadows and cottonwood โ€˜oasesโ€™ in other desert places, culminating in a lush labyrinthian delta on a dyke it had built across the Gulf of California with debris from creating the Grand Canyon through the Colorado Plateau. Whatever was left in the stream after it made its way through the delta went back into the ocean from which it had come โ€“ and one imagines there were many drier years when there was not enough water left below the delta to go into the ocean after the early summer flood finished.

We tend to make a big deal about the Colorado River no longer flowing to the ocean now due to our heavy use, but there are many desert rivers around the world that donโ€™t flow into the oceans; some forty streams flow into the Great Basin from surrounding mountains and plateaus โ€“ some of them respectable rivers like the Truckee, through Reno โ€“ and they all gradually disappear there, after nurturing riparian life (including some ranches and towns), enduring evapotranspiration, and sinking into aquifers. President Theodore Roosevelt, often called the father of American conservation, considered freshwater going unused into the ocean to be a โ€˜waste.โ€™

But understanding the nature of the desert river, and how it is different from a humid-region river like the Mississippi, offers some clues about an intelligent river system for storing and distributing the river. The vast majority of the users of the riverโ€™s water, especially the modern human users, are in the desert lands below the headwaters region โ€“ the โ€˜losingโ€™ (โ€˜givingโ€™) portion of the river: in the higher โ€˜cold desertsโ€™ above the canyon region, and the subtropical โ€˜hot desertsโ€™ below the canyons.

Healthy mountain meadows and wetlands are characteristic of healthy headwater systems and provide a variety of ecosystem services, or benefits that humans, wildlife, rivers and surrounding ecosystems rely on. The complex of wetlands and connected floodplains found in intact headwater systems can slow runoff and attenuate flood flows, creating better downstream conditions, trapping sediment to improve downstream water quality, and allowing groundwater recharge. These systems can also serve as a fire break and refuge during wildfire, can sequester carbon in the floodplain, and provide essential habitat for wildlife.

There are also water users in the headwaters region. Largest by far are the forests that ring most of the mountains, along with other plant and animal life inhabiting those mountain-forest regions. There are also humans in the headwaters, mostly in or near towns supporting mining or outdoor recreation, but what makes the most sense is to consider the human users as outliers of the โ€˜losingโ€™ basin below the headwaters โ€“ which they are, literally, producing little of what they need to live there but importing moat of it from or through the desert economy. The forests, on the other hand โ€“ as we will see โ€“ are intimately involved in the riverโ€™s water production processes, in both positive and negative ways.

These two distinctly different parts of the river suggest a more natural division of the river into two โ€˜basinsโ€™ than the political division under the Compact: the โ€˜gaining riverโ€™ and the โ€˜losing/giving river,โ€™ each to be managed toward a specific goal: for the gaining river, how to optimize the quantity of water flowing out of the headwaters; and for the losing/giving river, how to optimize the uses and minimize unnecessary losses.

This deliberately breaks up the current โ€˜two-basin divisionโ€™ โ€“ a โ€˜temporary equitable divisionโ€™ adopted in 1922 because the compact commissioners did not know enough about their the river or their own state futures to do the eight-way division (including Mexico) they had set out to do. The two-basin division was most basically an expedient way of persuading Congress that they were together in their search for an equitable division that would only become possible when there was โ€˜a greater fund of informationโ€™ that would enable those following them to do a proper division of the use of the riverโ€™s waters, but meanwhile โ€“ letโ€™s build the big dam.

Dividing the river into its โ€˜water productionโ€™ basin and its โ€˜water consumptionโ€™ basin would have the potential benefit of starting again with nearly all of the users in a single โ€˜consumptionโ€™ basin, while giving them all joint responsibility for taking care of the โ€˜water productionโ€™ basin. Itโ€™s a potential start on at least perceiving the river as a single shared responsibility, as opposed to the current perception of each state in it for its own needs and yielding as little as possible to the other states.

Thatโ€™s where weโ€™ll start next time โ€“ with the big question for the losing/giving river, the desert part of the desert river: how to get beyond Compact fantasies, and divide the use of the diminishing river we actually have among the vast multitudes of users (see the graph at the beginning). Thatโ€™s a point at which I think it would be smart to abandon the hydrologic term โ€˜losingโ€™ for a more political term โ€“ not a โ€˜losing riverโ€™ but a โ€˜giving riverโ€™ -which is what it is once it leaves the headwaters. And the challenge of โ€˜dividing the giftsโ€™ of the giving river at least starts with a more positive feel than โ€˜sharing out the lossesโ€™ from a losing riverโ€ฆ.

Meanwhile โ€“ vote! As if the future depended on it because it does. [ed. emphasis mine]

October 12, 2026

Denver Waterโ€™s collection and service areas continue to face severe drought conditions, with historically low snowpack. Denver Water depends on mountain snowpack for its water supply, which serves 1.5 million people in Denver and surrounding suburbs.

As a result, on March 25, 2026, the Denver Board of Water Commissioners declared a Stage 1 drought, seeking a 20% reduction in water use to preserve water levels and avoid even stricter mandatory restrictions later this summer. On April 8, 2026, the board approved the implementation of temporary drought pricing, starting with May water use and reflected in June bills, to signal the premium value of water during droughts and help incentivize customers to save water.

On Aug. 26, 2026, the board amended its Stage 1 drought resolution to prohibit lawn watering as of Oct. 1. The ban on lawn watering and all spray irrigation remains in effect until the board determines how and when lawn watering can resume. That means sprinklers need to remain off in spring of 2027, pending an official resolution from the Board of Water Commissioners.

Customers are warned of heavy fines for lawn watering or using spray irrigation after Sept. 30. Penalties for violating the ban begin at $500 for single-family customers. 


Snowpack and water supply update

  • In Denver Waterโ€™s collection system, the 2025-26 snowpack peaked more than a month earlier than normal and at the lowest levels observed in the past 40 years:
    • Colorado River Basin: Snowpack peaked March 18, 2026, at 58% of normal, the second-earliest date and second-lowest peak on record. (Typical peak date is April 24.)
    • South Platte River Basin: Snowpack peaked March 17, 2026, at 42% of normal, the second-earliest date and the lowest peak on record. (Typical peak date is April 26.)
  • Snowpack and melting conditions were unprecedented, with accelerated spring melting that started in mid-March. Customers need to save water to stretch supplies.
  • Streamflow forecasts called for runoff levels to be 10-40% of normal in 2026.
  • Reservoir storage conditions are below average.ย As of Oct. 12, 2026, reservoirs were 67% full, versus an average of 90% full for this time.ย 

Water use and conservation update

  • Quote from Greg Fisher, Denver Water’s manager of demand planning:ย 
    • โ€œOur customers did a great job shutting off their sprinkler systems in response to our Oct. 1 cutoff for lawn watering. Water use Oct. 1 through Oct. 11 was 34% below the five-year average,” said Greg Fisher, Denver Water’s manager of demand planning.
    • โ€œThis is a good start to preserving our critically important water supplies, because Denver Waterโ€™s reservoir storage levels are currently at 67% full, well below the average of 90% for this time of year.
    • โ€œWeโ€™re all hoping for a good winter, but itโ€™s extremely unlikely that weโ€™ll see enough snow โ€” and more importantly, a robust spring runoff โ€” to fully fill our reservoirs next year. Every customerโ€™s conservation efforts remain especially important as we work together to stretch our storage supplies heading into the winter.โ€
    • Customers can do their part byย making water-efficient upgrades, indoors and outdoors, including rethinking their yards. These steps preserve water supplies and create moreย adaptable and drought-resilient landscapesย that fit naturally into our climate.ย Read on TAP:ย Simple strategies to save water at home.
  • Customers are reminded of theย ban on lawn watering and spray irrigation as of Oct. 1.
    • Trees, shrubs and perennials may be watered any day with a hand-held hose with a shut-off nozzle or low-volume, non-spray irrigation (such as a drip system).ย They may not be watered with spray irrigation.
    • Denver Water will not be issuing watering exemptions for new turf installations.

For its part, Denver Water has proactively reduced its spending, taking steps that include enacting a hiring freeze and reviewing maintenance and other projects to see which ones could be deferred. We are also looking into other ways to increase supply by activating agreements that allow us to capture additional water that is typically unavailable during normal conditions.

This year marks the fifth time since 2000 that Denver Water has issued a Stage 1 drought, and the first since 2013. Prior to 2013, the board declared a Stage 1 drought in 2002, 2003 and 2004.

July 2026

Background & Study Purpose

This study is an update to a 2012 Report that explores the relationship between water and economic activity in a portion of western Colorado where the interaction of precipitation, elevation, and location produces water for the Headwaters Region, much of Colorado, and the Western United States.

The Headwaters Region encompasses the headwaters of the Colorado River and its tributaries. The Headwaters Counties consist of Eagle, Grand, Gunnison, Pitkin, Routt, and Summit County, depicted in Figure 1-1, on the next page. The water in the Headwaters Counties plays a special, dual role in meeting the needs of residents, businesses, and visitors while at the same time, meeting legal obligations for providing water to 40 million people in Colorado and the western U.S.

The study rests in the fact that water resources emanating from the Headwaters Counties are neither consistent nor unlimited, subject to considerable future uncertainty. Besides year-to-year weather variations, longer term climate changes are evident, and climate scientists expect these trends in climate change to continue. Regardless, economic activity in the Headwaters Counties is not standing still; leaders there seek prosperity, looking to further develop economic activity in their counties, the same as all counties around the State. At the same time, water providers on the Front Range in Colorado are seeking increased water supplies, identifying transmountain diversions (TMDs) from the Headwaters Counties as a potential source.

Couple this with the uncertainty related to interstate Colorado River allocations under the Colorado River Compact, and it is clear the Headwaters Counties should be worried about water scarcity. In short, all these forces bear down upon the increasingly less predictable but indispensable water supplies originating in the Headwaters Counties.

Representing the Headwaters Counties, the Northwest Colorado Council of Governments (NWCCOG) through its Water Quality/Quantity Committee (QQ) sought a current understanding of the relationship of the local economies to the evolving availability of surface waters. NWCCOG retained Harvey Economics (HE) to prepare this study.

๐Ÿ”ญ OVERSIGHT ๐Ÿ‘ฎ๐Ÿผ

A bipartisan group of federal lawmakers, including Sens. Martin Heinrich (D-NM) and Mike Lee (R-UT), introduced legislation aimed at streamlining and accelerating federal environmental reviews and permitting for major projects on Sept. 30. The Bipartisan Affordability and Jobs Act would lower or remove regulatory hurdles for large-scale renewable and transmission projects, fossil fuel pipelines, mining projects, and other industrial projects such as data centers and accompanying power facilities.

The push for faster permitting has been in the pipeline for years, and garnered the support of the renewable energy industries and climate advocates in more recent years, after seeing huge transmission projects such as SunZia and TransWest Express languish in red tape for nearly two decades due to potential impacts to wildlife and cultural sites. The lines were purportedly designed to carry renewable energy back and forth across the West to provide whatโ€™s known as โ€œgeographical smoothingโ€ of variable solar and wind resources. These sorts of delays, according to permitting reformists, were stifling the energy transition.

Shortly after the billโ€™s details were made public, ecologically minded environmental groups raised red flags, warning that, as written, the legislation would weaken bedrock environmental laws, including the National Environmental Policy Act and Endangered Species Act, and take away the publicโ€™s power to block or force revisions to projects of all kinds, including ones that will lead to more fossil fuel burning and more greenhouse gas emissions. They pointed out that not only was the notoriously anti-environment Lee sponsoring the bill, but it also had a full-throated endorsement of the American Petroleum Institute.

This triggered a vehement, some might even say toxic, reaction from the climate hawks and Abundance adherents that support reform, and ignited a rhetorical civil war within the environmental movement on social media.

The Abundance movement supports the bill, allying itself with the petroleum and tech industries, because it would make it easier to build large clean energy facilities and the transmission needed to move it around. They are operating on the belief that building more and bigger clean energy projects is the only way to battle climate change โ€” even if it also opens the door to more fossil fuel burning. This theory assumes that the market will favor clean energy projects, even if policy favors โ€œall of the above.โ€ 

Marc Levitt, director of environmental regulatory reform for the Breakthrough Institute, called the bill a โ€œheroic breakthrough for permitting reformโ€ and โ€œa massive down payment towards the energy abundant future that Americans deserve.โ€

Opponents, however, say that pushing energy development of all kinds will not only decimate cultural and natural resources and burden humans and wildlife, but it also will not do much to solve the climate crisis if every new solar array or transmission line is matched with a new natural gas pipeline or power plant. 

โ€œThe permitting deal is a betrayal of public lands, water and wildlife, and environmental justice values that Westerners depend on for clean air and water, places to hike, hunt, and fish, and the inestimable sense of freedom the West provides us all,โ€ said Erik Schlenker-Goodrich, executive director of the Western Environmental Law Center based in New Mexico.

The legislation also raises concerns that the Trump administration could use the legislation to further weaken environmental protections to benefit the fossil fuel, nuclear, mining, and data center industries, while still throwing up roadblocks to solar and wind development.

The Land Desk will have an analysis of the bill and how it might play out on the Land Deskโ€™s beat in the coming days.

๐Ÿ“– READING ROOM ๐Ÿง

The New Yorker has again ventured into the Four Corners Country, this time with a story by Peter Hessler about the Million Dollar Highway between Silverton and Ouray, โ€œone of Americaโ€™s scariest roads.โ€ I always enjoy Hesslerโ€™s writing, whether about Cairo or Nucla, and this storyโ€™s no exception. His descriptions of the many accidents and ensuing rescues on that stretch of road are vivid and, yes, scary. And his history of the area and Otto Mears, the roadโ€™s original builder, is compelling. But I have to take issue with the framing of the story, and the headline, which is: โ€œWhy doesnโ€™t anyone want to fix one of Americaโ€™s scariest roads?โ€ To which Iโ€™d respond: Does it really need fixing?

Look, traversing Red Mountain Pass can be daunting, especially during the spring freeze-thaw cycle when rocks are dislodged from the cliffs and tumble down onto the asphalt and the Mother Clineโ€™s human-sized icicles hang perilously over the pavement.Sometimes folks tragically go over the edge. Several plow drivers have perished on the road after getting pummeled by the Riverside Slide. In 1963, Reverend Marvin Hudson and his two teenaged daughters were hit by the Riverside, swept into the gorge, and buried (oddly, Hessler leaves this story, one of the most nerve-chilling, out of the story). This problem has been largely solved by simply shutting the road when danger is high. 

So sure, the road can be dangerous and nerve-racking, but frankly, I can think of plenty of far scarier โ€” and statistically more dangerous โ€” stretches of road. Highway 550 between Albuquerque and Bloomfield is a virtual carnage factory, especially when the oil and gas fields are busy with water and oil-hauling trucks. Highway 191 between Monticello and Moab is super sketchy โ€” and deadly. Or how about I-10 in the Phoenix area, I-40 just about anywhere, or I-70 dropping from the mountains into the Coloradoโ€™s Front Range on a weekend afternoon?

Back in the late 1980s, Colorado spent about a half-billion dollars to โ€œfixโ€ I-70 through Glenwood Canyon. Now itโ€™s the site of multi-vehicle accidents, rockslides, debris flows, and not infrequent closures due to the above. So, yeah, Red Mountain Pass doesnโ€™t need fixing. People just need to slow the hell down and pay attention.

The Southeastern #Colorado Water Conservancy District and the Bureau of Reclamation sign Arkansas Valley Conduit Repayment Contract — Chris Woodka (secwcd.org) #ArkansasRiver

From email from Southeastern Water (Chris Woodka):

October 7, 2026

A contract to repay the federal government for the Arkansas Valley Conduit (AVC) was signed Wednesday, October 7, 2026, by the Southeastern Colorado Water Conservancy District and the Bureau of Reclamation.

โ€œThis is an incredibly important day for the District, Reclamation and all of our constituents for the AVC,โ€ said Bill Long, president of the District Board of Directors. โ€œWe still have a long way to go, but we are moving forward. This is an important milestone.โ€

Long held up one of the golden frying pans that were sold up and down the Arkansas Valley in the 1950s to raise money to promote the Fryingpan-Arkansas Project, an effort that eventually led to President John F. Kennedy signing the Fry-Ark Project legislation. The AVC is the final project element of that original Fry-Ark project legislation.

โ€œWithout the Arkansas Valley Conduit, the Valley will not be developed as it would have been otherwise. You cannot attract industry without a supply of clean water,โ€ Long said.

Kevin Karney, chairman of the Districtโ€™s AVC Committee, was an Otero County Commissioner when the AVC was relaunched in 2000. Karney was a member of the group searching for a way to provide better quality water for the Lower Arkansas Valley.

โ€œThe only solution that has risen to the top is the Arkansas Valley Conduit,โ€ Karney said.

Arkansas Valley Conduit map via the Southeastern Colorado Water Conservancy District (Chris Woodka) June 2021.

Reclamation and the District are building the AVC in a collaborative project, with Reclamation building the 130-mile trunk line from Pueblo to Lamar and the District building spur and delivery lines to connect 38 water systems to the trunk line. The total cost of the project is estimated to be $1.4 billion.

The AVC will provide water to 50,000 people served by cities, towns, water districts and private water companies.

Participants are required under federal law to pay 35 percent of the AVCโ€™s cost. Any costs incurred by the District for construction of spur and delivery lines will be credited to the 35 percent repayment. The The remainder will be repaid with miscellaneous revenues generated from the Fryingpan-Arkansas Project (mainly from excess storage capacity contracts in Pueblo Reservoir).

The contract defines the responsibilities for design and construction, facilities ownership, and when the repayment period will start with substantial completion of the AVC. Reclamation will retain ownership of the trunk line and related facilities it is building, as well as the SCADA (Supervisory Control and Data Acquisition) System that will be used to operate the AVC. The District will construct and own the delivery lines, and any SCADA system implemented must comply with federal cybersecurity requirements.

The Contract reaffirms Pueblo Waterโ€™s role for conveyance of AVC water using capacity in its system in accordance with the conditions outlined in the 2022 Three-Party Contract between Reclamation, the District and Pueblo Water.

Provisions are included that would allow delivery of AVC water to participants before the AVC Project is completed. The Contract defines how costs for water delivered, supplies, and various services will be divided between the District and Reclamation prior to completion of construction.

When the AVC is substantially complete, responsibility for all OM&R costs will be transferred to the District. The District is developing a cost model in order to provide reliable estimates of operation, maintenance and replacement (OM&R) at partial and full capacity.

October 7, 2026

A new collaboration between state and local organizations in the San Luis Valley aims to conserve and protect the region’s water and lands. The San Luis Valley Conservation and Legacy Projectโ€™sย objectives include leveraging the areaโ€™s natural assets and cultural heritage to create economic opportunity. A recent gathering of local and state leaders identified ways to support agriculture and outdoor recreation in the region and serve the long-term interests of communities. Priorities include safeguarding water resources in both the Rio Grande River and in the groundwater aquifers. That could include paying farmers to leave water in the river and its tributaries to help create and maintain healthy riparian environments for wildlife, fishing recreation and agriculture by potentially paying farmers to leave water in the river and its tributaries. Also among the goals are promoting a regional identity and cooperation among various stakeholders, as well as attracting responsible tourism that brings money to the area without increasing the risk of wildfire, trashing the environment or straining search and rescue teams.

October 7, 2026

Representatives of the Colorado River Water Conservation District (CRWCD) presented a detailed update about West Slope water, Shoshone water rights and more. Taking a look at water conservation proportionality, Lindsay DeFrates, CRWCD public information officer, later told The Sun that the CRWCD believes that proportionality is critical as the state investigates how to implement the Contribution Program, which allocates Coloradoโ€™s share of federal money awarded to the Upper Basin states to conserve water. โ€œIt will pay people to use less water,โ€ she said.ย  At Mondayโ€™s meeting, CRWCD General Manager Andy Mueller expressed concern regarding the disproportionate impact of water conservation on western Colorado agriculture. โ€œIf you donโ€™t have state laws requiring proportionality from all Colorado River users, meaning the Front Range as well, all of that water not only comes off the West Slope, it comes out of West Slope [agriculture],โ€ he said.

Coloradoโ€™s conservation goal is 100,000 acre-feet of water. โ€œIf all of that comes out of West Slope [agriculture], thatโ€™s a big hit to our local economies, to our small towns, to our agricultural industry, and it may be just the beginning of what we view as a permanent program,โ€ Mueller added. 

As for the Shoshone water rights issue, CRWCDโ€™s Strategy Chief Amy Moyer told the BOCC that the purchase price is $99 million and all but $1.6 million has been raised from the CRWCD, the federal government and state and local governments, including $3 million from Garfield County. โ€œOur plan is to continue working with communities up and down the river,โ€ Moyer said. โ€œBut we may want to sit down with you as we look to close that $1.6 million gap.โ€

Getches-Wilkinson Center: The Colorado River Upper Initial Units Take Center Stage — Eric Kuhn, Anne Castle, Jack Schmidt, Kathryn Sorensen, Katherine Tara

Flaming Gorge Dam: USBR

Click the link to read the report on the Getches-Wilkinson Center website (Eric Kuhn,*ย Anne Castle,โ€ ย Jack Schmidt,โ€กย Kathryn Sorensen,ยงย Katherine Tara**). Here’s the Introduction:

October 6, 2026

SUMMARY OF KEY POINTS

  • In 1956, Congress authorized the Upper Initial Unitsโ€”Flaming Gorge Reservoir, Navajo Reservoir, and the Aspinall Unit (UIUs)โ€”for a variety of water use purposes in the Upper Colorado River Basin, including compliance with the 1922 Colorado River Compact (1922 Compact). The historical record is clear that the primary reason these reservoirs exist is to satisfy the math of the 1922 Compact and the obligations it imposed on the Upper Division States regarding flows at Lee Ferry.
  • The size and operation of the UIUs was based on the math of the river as we understood it from the 1930s through the mid-1950s (natural flows, projected uses, and the drought of record). This math no longer works. Total water use in the Colorado River Basin has consistently exceeded the available supply since 2000. Until this fundamental problem is solved, releasing water from the UIUs only delays necessary permanent reductions in water use and provides some degree of temporary management flexibility.
  • The 1948 Upper Basin Compact contemplates delivery of a required quantity of water at Lee Ferry. Article V gives the Upper Colorado River Commission (UCRC) the authority to allocate the capacity of the UIUs between providing water for use within the Upper Division States and providing water for common benefit purposes (delivering water to Lee Ferry). The policy has always been that 100% of the capacity of Navajo Reservoir is allocated for water use in New Mexico and 100% of the capacities of Blue Mesa and Flaming Gorge Reservoirs is allocated for common benefit purposes.
  • There is no doubt that Flaming Gorge and Blue Mesa Reservoirs exist to meet a portion of the obligation of the Upper Division States under Article III of the 1922 Compact. As of October 1, 2026, the ten-year Lee Ferry flow will be about 81.2 million acre-feet (MAF), and under the Lower Division Statesโ€™ interpretation of the 1922 Compact, the Upper Division States may be in a compact deficit by 800,000 acre-feet (or more).
  • Yet over 2.0 MAF of water remains in active storage in Flaming Gorge Reservoir; more than enough water to erase the deficit and put the Upper Division states back in compact compliance as interpreted by the Lower Basin, if only for the short term.
  • The Upper Division States assert that they are in full compliance with the 1922 Compact.ยน Thus, in their view, delivering additional UIU water to Lee Ferry now would be a waste of stored water that they may need in the future. They question why yet another reservoir should be further drawn down when the Basin has not solved the fundamental problem of demand exceeding supply.
  • The stored water available in Flaming Gorge Reservoir has increased in importance to the entire basin. The Lower Division states view it as a source of water that can be delivered at Lee Ferry to supplement the releases from Lake Powell and thereby fulfill the obligations of the Upper Division States under the 1922 Compact. The Bureau of Reclamation is using Flaming Gorge as a source of water to protect critical infrastructure at Glen Canyon Dam, including hydropower generation. The Upper Division States view Flaming Gorge as a source of water for their current and future benefit; the water stored there could be used to comply with an adverse decision by a court or Special Master.
  • There remain unresolved issues concerning the use of water stored in the UIUs, with seemingly conflicting provisions in the 1948 Upper Basin Compact and the 1970 Long-Range Operating Criteria that currently govern the operation of these reservoirs. These issues could govern future releases from the UIUs but have not been explicitly addressed in the Post-2026 Record of Decision or the 2027-2028 Operating Rules.
  • The math of the 1922 Compact and its Lee Ferry flow provision, together with the directives of the Long-Range Operating Criteria, can no longer be reconciled with todayโ€™s hydrology and long-term average basin-wide consumptive use. The Basin States can argue about compliance with various conflicting provisions, but the fundamental problem is that the rules were designed for a different river. We need new operating rules that reflect the river we have today. The choice in finding these new rules is likely to be between a compromise that is painful to all parties or a zero-sum Supreme Court decision that determines who gets what little water there is and who does not.

INTRODUCTIONยฒ

The 1956 Colorado River Storage Project Act (1956 CRSPA)ยณ authorized construction of Glen Canyon Dam, which created Lake Powell, and three additional major upstream storage projects; Flaming Gorge Dam and Reservoir, Navajo Dam and Reservoir, and the Curecanti Unit (Blue Mesa, Morrow Point, and Crystal Dams and Reservoirs, now called the Aspinall Unit). The 1956 CRSPA was designed as a broad authorization for Upper Basin water development within the bounds of the 1922 Compact. The legislation authorized construction of storage dams, powerplants,โด numerous irrigation projects, and trans-basin diversions. Among the purposes of 1956 CRSPA were โ€œregulating the flow of the Colorado River, storing water for beneficial consumptive use, making it possible for the States of the Upper Basin to utilize, consistently with provisions of the Colorado River Compact, the apportionments made to and among them in the Colorado River Compact and the Upper Colorado River Basin Compact, respectively . . ..โ€โต Flaming Gorge, Navajo, and the Aspinall Unitโถ are collectively referred to as the โ€œUpper Initial Unitsโ€ (hereafter, UIUs). The three UIUsโ€™ total live storage capacity is 6.15 million acre-feet (MAF), of which 5.10 MAF is โ€œactiveโ€ storage.โท On October 1, 2026, the total live storage in the three reservoir systems was 3.47 MAF. The Appendix contains a detailed description of each of the UIUs, with information on capacity, operations, and contract obligations.

For over 60 years, the three UIUs have been storing system water and producing hydroelectric power. These reservoirs, however, previously played a relatively small role in the operation of federal reservoirs of the Colorado River Basin (Basin) as a whole. The focus of the Basinโ€™s competing interests has primarily been on operation of Glen Canyon Dam and Hoover Dam that form Lake Powell and Lake Mead, respectively. These two reservoirs are the largest in the United States and presently store approximately 66% of all the water in the 12 federal reservoirs reported in Reclamationโ€™s 24-Month Studies. During the debate and development of major policy actions for the Colorado River, such as the 1970 Coordinated Long-Range Operating Criteria,โธ 2001 Interim Surplus Guidelines,โน and the 2007 Interim Guidelines,ยนโฐ the operations of the UIUs were barely mentioned. However, as storage in Lake Powell and Lake Mead has declined, the importance of the UIUs has increased.

The Bureau of Reclamation (Reclamation) operates each of the three UIUs under separate Records of Decision (ROD). Each is operated in a manner that balances many competing interests such as: storage for 1922 Compact compliance, the delivery of stored water for Upper Basin consumptive uses, the delivery of water in fulfillment of Tribal water right settlement obligations, flood control, hydropower generation, on-reservoir recreation, downstream river recreation, sport fisheries in the reservoir and in the stream below the reservoir, and the flow needs of threatened and endangered fishes. Reclamation operates the UIUs in a transparent manner, and each has a local constituency that is closely involved in how their project is operated.

The UIU obscurity honeymoon ended in 2019 when the Upper Division States proposed what became the Drought Response Operations Agreement (DROA) as a component of their 2019 Drought Contingency Plan.ยนยน Arguably, under federal law, the Secretary of the Interior (Secretary) has broad authority to unilaterally move water from the UIUs downstream to Lake Powell. However, Reclamation took a more collaborative approach in the DROA: it was an inter-governmental agreement among the US (through Reclamation) and the states of Colorado, New Mexico, Utah, and Wyoming. DROA authorized releases from the UIUs to the extent necessary to achieve the stated operational objective of minimizing the risk of Lake Powell falling below a target elevation of 3525 ft, and thereby:

  • helping to ensure the Upper Division States will continue fulfilling their interstate water compact obligations while exercising their rights to develop and utilize the Upper Basinโ€™s Compact apportionment,
  • maintaining the ability to generate hydropower at Glen Canyon Dam, and
  • minimizing adverse effects on resources and infrastructure in the Upper Basin.ยนยฒ

DROA is subject to numerous constraints, including:

  • Water available in the UIU reservoirs,
  • Protection of authorized purposes of each CRSP unit (water supply, endangered species, recreation, hydropower, etc.),
  • Consultation with the Upper Division States and the Upper Colorado River Commission, and
  • Operating criteria established in the agreement and the associated Records of Decision.

In 2021, a total of 181,000 acre-feet of DROA releases were planned pursuant to the Secretaryโ€™s emergency authority: 125,000 acre-feet from Flaming Gorge, 36,000 acre-feet from Blue Mesa, and 20,000 acre-feet from Navajo. Due to dry conditions, the 20,000 acre-feet release from Navajo Reservoir was cancelled, resulting in a total release of 161,000 acre-feet.ยนยณ DROA was implemented again in 2022 pursuant to consultation and agreement with the Upper Division Statesโ€”approximately 463,000 acre-feet of water from Flaming Gorge Reservoir were released. Both releases were intended to help maintain an operational target elevation of 3525 ft in Lake Powell.ยนโด The DROA water released from Flaming Gorge Reservoir and Blue Mesa Reservoir in 2021 and 2022 was completely recovered after the moderately wet winter of 2023.ยนโต DROA includes specific provisions addressing storage recovery after a DROA release is made. DROA expires contemporaneously with the 2007 Guidelines, but operations to recover storage releases made before Oct. 1, 2026, continue for as long as necessary.ยนโถ

In response to the near-record low 2026 runoff and the unprecedented low reservoir levels in Lake Mead and Lake Powell, DROA releases were again implemented to supplement Lake Powell levels, and this time with even greater urgency and impact. To help maintain the elevation of Lake Powell above 3500 ft, on April 23, 2026, Reclamation began making additional DROA releases from Flaming Gorge Reservoir.ยนโท According to the September 2026 24-Month Study, the planned release from Flaming Gorge will total one million acre-feet between April 2026 and April 2027, but Reclamation retains the flexibility to adjust the timing and amount based on actual hydrologic conditions. Citing contractual obligations and unusually low storage, there are no planned DROA releases scheduled for 2026 from either Blue Mesa Reservoir or Navajo Reservoir.ยนโธ

As annual Colorado River Basin runoff in the 21st century is consistently lower than in the 20th century and the โ€œRatchet Effectโ€ is evident in reservoir storage basin-wide, disputes over the operation of the UIUs between the Upper Division States and Lower Division States have increased and indeed now are nearly as critical and strident as the disputes over water deliveries from Lake Powell to Lake Mead.ยนโน The Lower Division Statesโ€™ May 1, 2026, Proposal for Short-Term Operations of the Colorado River included proposed operating criteria for the UIUs that would expand their role in maintaining Lake Powell elevations and effectively subordinate the refilling of the UIUs until there is sufficient water in Lake Powell to support the delivery of 8.23 MAF per year.ยฒโฐ The stated intent is โ€œto share the benefit of improved hydrology between both basins.โ€ยฒยน On May 13th, 2026, the director of the Arizona Department of Water Resources told the Arizona Re-Consultation Committee that under Arizonaโ€™s interpretation of the Law of the River, the 1956 CRSPA specifically subordinates the delivery of contract water from the UIUs and the refilling of those reservoirs to water deliveries to the Lower Basin and Mexico under the 1922 Compact.ยฒยฒ

The Upper Division States believe the operation of the UIUs proposed by the Lower Division States is outside the scope of the Post-2026 NEPA process and cannot be incorporated into the Record of Decision as part of the 2027โ€“2028 operations plan.ยฒยณ Further, some UCRC commissioners pointed out that under the 1956 CRSPA, there are multiple purposes of the UIUs including supporting consumptive uses within the Upper Basin.ยฒโด At the 2026 Getches-Wilkinson Center Conference on the Colorado River, then-Acting Reclamation Commissioner Scott Cameron noted that Reclamation would aggressively operate the UIUs under their RODs to help manage Lake Powell levels, but added that the Secretary has, and will use, if necessary, emergency authorities to operate the UIUs outside the bounds of their RODs.ยฒโต

The Record of Decision (ROD) released on August 21, 2026, for the “Decision Framework for Colorado River Guidelines: Coordinated Operations of Lake Powell and Lake Mead (2027โ€“2036)” addressed the operation of the UIUs in a general manner. The ROD states:

โ€œIn carrying out the Decision Framework, the Department will continue to coordinate the operation of Lake Powell, Lake Mead, and the Colorado River Storage Project (CRSP) Upper Initial Units โ€“ specific reservoirs above Lake Powell โ€“ pursuant to Section 602 of the Colorado River Basin Project Act of 1968 (CRBPA). Consistent with each facilityโ€™s existing ROD, the CRSP Upper Initial Units remain an operational tool available to the Secretary, when necessary, to release additional water to increase the elevation at Lake Powell to protect critical Federal infrastructure.โ€ยฒโถ

While the Decision Framework Operational Sideboards of the ROD include the โ€œPotential for maximum use of CRSP Upper Initial Units within their respective RODs to release additional water if needed to protect critical infrastructure,โ€ they also allow for greater releases than described in their respective RODs:

“The Decision Framework establishes consultation thresholds associated with critical reservoir elevations. When projected reservoir conditions approach or fall below the consultation thresholds identified in the operational sideboards, the Secretary will coordinate and consult with the Basin States, Basin Tribes and other affected parties, as appropriate, regarding additional operational actions that may be appropriate to reduce risks to critical Federal infrastructure and maintain system reliability.ยฒโท”

Further, โ€œSuch consultations may include consideration of additional reductions in water use, adjustments to coordinated reservoir operations of Lake Powell and Lake Mead, use of the CRSP Upper Initial Units, or other operational actions.โ€ยฒโธ

Notably, the Decision Framework does not mention using the UIUs for making deliveries of water to Lee Ferry when there is insufficient water in Lake Powell for compliance with the 1922 Colorado River Compact (1922 Compact).

UIU storage recovery timing and amounts are not specified in the 2027-2028 Operating Guidelines,ยฒโน but Interiorโ€™s response to the Lower Basinโ€™s May 1st proposal stated that it:

“intends to refill the UIUs as soon as practicable to ensure water remains available for any additional infrastructure protection releases, while avoiding further risk to critical infrastructure during recovery operations. Based on prior operational experience, recovery operations were initiated once Lake Powell was no longer projected to continue declining. Reclamation would apply a similar approach for future UIU recovery operations and would consider actual hydrology and Basin-wide conditions before initiating recovery actions.ยณโฐ”

What is clear is that the water stored in the UIUs is an increasingly important resource coveted by the Upper Division States, the Lower Division States, Basin Tribes,ยณยน and Reclamation. It is also clear that each of these entities has a different perspective on the priorities under which the UIUs will be operated in the future. But it is important to recognize that while the water released by the UIUs in 2021, 2022, and 2026 provided critical benefits, especially for maintaining Lake Powell above target thresholds, DROA-like releases are not a solution to the Basinโ€™s fundamental problem โ€“ systematic use of more than the available water supply. The operation of the UIUs may buy time and provide additional flexibility for reservoir system management, but it does not create any new water.

The debate over the future use of the UIUs has also exposed and amplified several long-standing disputes over the interpretation of the key provisions of the Law of the River,ยณยฒ and ambiguities in the major federal legislation that authorized the construction and operation of the riverโ€™s major federal reservoirs. A primary disputed issue facing the Colorado River Basin today is how much water must flow at Lee Ferry to satisfy the Upper Division Statesโ€™ 1922 Compact obligations. As stated above, delivering water to Lee Ferry was a core purpose for both Lake Powell and the three UIUs.ยณยณ

On August 24, 2026, the state of Nevada, the Colorado River Commission of Nevada, and the Southern Nevada Water Authority filed a complaint for declaratory action and injunctive relief requesting a declaration that the ROD, Final Environmental Impact Statement, and 2027-2028 Guidelines are in violation of the Administrative Procedure Act, the National Environmental Policy Act (NEPA), and the Law of the River.ยณโด The complaint requests an injunction halting the implementation of the ROD and Operating Guidelines. Among other arguments, the plaintiffs claim that the Secretary failed to consider the exercise of authority to operate the UIUs in compliance with the Law of the River and NEPA.

The ROD states that the UIUs will be the subject of a new DROA agreement (referred to as a โ€œframeworkโ€) that is currently being negotiated among Reclamation and the Upper Division States. This proposed agreement, drafts of which have not been released to the public, has already received criticism from the State of Arizona. If finalized, it could also be the subject of future litigation.ยณโต In the remainder of the paper, we explore the history of the UIUs from their conception to the present day to provide context and rationale for future operations.

1 The position of the Lower Division States is that the Upper Division States must not deplete the ten-year flow at Lee Ferry below 75 MAF PLUS deliver half of the annual treaty delivery to Mexico. The normal treaty delivery is 1.5 MAF, so the total ten-year delivery obligation could be 82.5 MAF. In recent years, under Minutes 323 and 330, the annual delivery has been less, but because these Minutes also create water that Mexico can store โ€“ calculating how much delivery the Upper Division States must share is not a simple matter. In any event, however, it appears that 81.2 MAF is less than the required 10-year flow pursuant to the Lower Division Statesโ€™ legal position.

1 The Upper Division States do not agree that their obligation to Mexico under Article III(c) of the 1922 Compact is half of the annual delivery to Mexico under the 1944 Treaty every year.

2 This paper describes the authorization of the UIUs, the events leading up to that authorization, and some of the debate that resulted in the compromises in the 1956 Colorado River Storage Project Act (1956 CRSPA). The authors recognize that there are several detailed histories of CRSPA that address different aspects of its origins and come from a different perspective. Among these are: MARC REISNER. CADILLAC DESERT: THE AMERICAN WEST AND ITS DISAPPEARING WATER (1986, Viking Press); M. HARVEY, A SYMBOL OF WILDERNESS: ECHO PARK AND THE AMERICAN CONSERVATION MOVEMENT (Univ. N.M. Press 1994, 2nd Ed. Univ. of W.A. Press, 2000). Recognizing the value and insights of these previous works, this paper seeks to place the UIUs and their origins within the context of todayโ€™s hydrology and disputes.

5 1956 CRSPA Preamble.

6 The three reservoirs in the Aspinall Unit are Blue Mesa, Morrow Point, and Crystal. Only Blue Mesa is operated for river regulation and storage. Future references to storage in the UIUs include Blue Mesa, Flaming Gorge and Navajo Reservoirs, but not Morrow Point and Crystal Reservoirs. A number of additional reservoirs were authorized by the 1956 CRSPA (and subsequent federal legislation) as components of participating projects. All of these reservoirs have specific project functions. Several of these reservoirs store a significant amount of water. Strawberry Reservoir, a component of the Central Utah Project, McPhee Reservoir, a component of the Dolores Project, and Fontanelle Reservoir, a component of the Seedskadee Project are three prominent examples.

7 The data sources for this paper are primarily the Hydrologic Database (HDB) and the 24-Month Studies, both maintained or prepared by the U.S. Bureau of Reclamation. We use โ€œlive storageโ€ to mean the amount of storage reported in the HDB or alternately, the 24-Month studies. The standard terminology for reservoirs is that live storage is the amount that can be physically withdrawn or released downstream. Active storage is the amount above the power plant penstocks (or primary outlet works for Navajo Reservoir). Inactive storage is the amount between the power plant inlets, and the low-level outlet works. Below the low-level outlet is the โ€œdead pool.โ€ In theory, live storage = active plus inactive storage. In practice, however, each reservoir has a different design and different management issues. It is possible that some live storage may not be accessible for downstream delivery and use. The figures provided for live and active storage in the UIUs do not include Crystal and Morrow Point reservoirs.

How a century-old pricing system has emptied the #ColoradoRiver: An absurdity of the Colorado River crisis is the role of heavy government subsidization of agricultural water use — Daniel M. Frey (BigPivots.com) #COriver #aridification

October 5, 2026

While fighting over water rights and priorities might take decades, the federal government can start aligning what agriculture pays for federal delivery with what municipal users already pay โ€” without waiting for a new compact or a courtroom fight over title.

We are told that nothing can be done about the Colorado River water crisis while officials allow powerful agricultural interests to keep using more of the river for hay and alfalfa than all cities and other industries in the basin combined.

In the Lower Basin, agricultural water districts pay roughly 6% of what municipal utilities pay at wholesale. That pricing perpetuates waste and low-value irrigation, discourages conservation, and undermines any real chance of restoring the riverโ€™s supplies.

Part I of this series (see โ€œAbsurdity of the Colorado River crisis,โ€ Big Pivots, Aug. 30, 2026) showed that nearly half the water put to human use in the Colorado River Basin goes to growing feed for cattle โ€” alfalfa, hay and silage โ€” while 40 million people depend on the same river for drinking water.

That is not a hydrology problem. It is a political one, built on the doctrine that the oldest water right always wins, no matter how the world around it has changed.

This installment goes one layer deeper, into the accounting. The story of the Colorado River is not only about who has the legal right to water. It is about how government pricing, contracts, and cost-shifting have supported overuse on low-value crops.

The volumes restated

Forage crops โ€” mostly alfalfa and hay grown to feed livestock โ€” consume close to half of all water used by people across the Colorado River Basin. In 2023, two separate studies by the Western Agricultural Economics Association and the Arizona Department of Agriculture (see Sources) concluded that in the Lower Basinโ€™s desert valleys, a substantial share is shipped overseas: up to 30% of Imperial Valley alfalfa and more than a fifth of Arizonaโ€™s hay.

In the Upper Basin, including Colorado, forage crops make up roughly 90% of agricultural irrigation, more than three times what Upper Basin households, businesses and industries consume combined. The degree and complexity of irrigation and infrastructure vary across the upper and lower basin. There are small farms and communities that have closely and carefully integrated water with highly efficient and effective irrigation.

It should also be understood that many farms and ranches in the Colorado River Basin, particularly in the Upper Basin, do not depend upon federal-financed infrastructure. This essay is not about them. Rather, it is about both farms and cities who benefit from federal infrastructure. Cities that are home to millions of people are asked to justify every toilet flush and lawn sprinkler while a crop with a modest market value drains the river. That imbalance might be easier to defend if the irrigators paid a market price. Instead, Lower Basin irrigation districts pay about 6% of what cities pay at wholesale.

How the government built โ€” and then discounted โ€” this system

Almost none of the infrastructure that makes Southwestern irrigation possible was built or paid for by farmers alone. The dams, canals, and reservoirs of the Colorado River system were constructed and financed by the U.S. Bureau of Reclamation, a Department of the Interior agency that has spent more than a century as the largest wholesaler of water in the country.

Under federal reclamation law, the government fronts the capital, and the beneficiaries โ€” irrigation districts, cities, power customers โ€” are supposed to pay it back over time.

Political power derailed equitable pricing during this past century. Reclamation law splits repayment onto two tracks. Municipal and industrial water is repaid over roughly 40 to 50 years โ€” with interest. Irrigation costs are repaid over the same window โ€” interest-free.

Congress wrote the interest-free exemption into the original Reclamation Act of 1902 to spur Western settlement. Homesteaders on arid land had no way to finance dams and canals themselves. Lawmakers reasoned that irrigated farms would eventually generate enough tax base and repayment to justify the up-front public investment.

Cities were not part of that original calculation. Municipal and industrial water became an authorized Reclamation purpose only in 1939, and it was placed on the standard interest-bearing track. The exemption made sense when the goal was populating an unsettled frontier. It has been revisited many times since โ€” always to loosen it โ€” but never ended for a basin now serving forty million urban residents.

That alone would be a meaningful subsidy. It gets larger. Reclamation law also lets irrigation districts apply for โ€œability to payโ€ relief. That economic review can cut a districtโ€™s repayment obligation below its actual share of construction costs if the government decides the district cannot afford the full amount or that the land is not productive enough to justify full-cost pricing. When those obligations go unpaid, the shortfall does not vanish. It is folded into what other customers pay โ€” chiefly hydropower sales and, on some projects, municipal and industrial users. Cities are not just paying full freight for their own water. On many federal projects, they and power customers are backstopping agricultureโ€™s unpaid balance, too.

In the Colorado River Basin alone, the federal government has put more than $8 billion, in unadjusted dollars, into three programs: Hoover Dam and the All-American Canal, the Colorado River Storage Project and the Central Arizona Project. Compounded at 4.6%, roughly what cities have paid to borrow over the past century, $8 billion would be worth more than $75 billion today. The power and municipal shares of those costs carry interest; the irrigation share does not. The financing model was never hidden. The Storage Project โ€” Glen Canyon, Flaming Gorge, Navajo, and the Aspinall Unit โ€” was promoted in the 1950s on the promise that power and municipal features would be repaid with interest and irrigation would not. Hydropower revenue from those dams still covers irrigation costs judged to be beyond farmersโ€™ ability to pay.

At that rate, repaying a construction cost interest-free over 50 years wipes out about 60% of its value compared with what municipalities pay. Add debt forgiveness, stretched repayment periods and โ€œability to payโ€ relief, and the discount grows: economist Richard Wahl found that once interest was counted, irrigators repaid only about fourteen cents of every dollar of irrigation construction costs.

What this looks like in dollars

The gap is not subtle. A December 2025 report from the UCLA Institute of the Environment and Sustainability and the Natural Resources Defense Council analyzed 217 water transactions across the Lower Basin states. The report found that agricultural water districts pay a weighted average of about $30 per acre-foot, while municipal utilities pay about $512.

An acre-foot is 326,000 gallons, enough to supply two to three households for a year. Under this system, a hay farmerโ€™s district pays about $30 and a utility serving a family in Phoenix or San Diego pays roughly $500 โ€” before treatment and local delivery. That is seventeen times as much for the same unit of a scarce public resource.

Federal repayment terms are only one reason for that gap. Under Western water law and most federal contracts, the water itself is essentially free; prices reflect the cost of storing, moving, and treating it, and city systems carry heavier pumping and treatment costs. However, the federal subsidy is part of the gap the public has financed directly โ€” and the part of Washington can most readily change.

Some agricultural districts, including Californiaโ€™s Imperial Irrigation District, the single largest holder of Colorado River water rights, pay the Bureau of Reclamation nothing at all for the water itself. Their contracts do not require payment for the raw supply. When the federal government paid for that same district in 2023 to leave water in Lake Mead, the contract rate was about $776 an acre-foot. The district had asked for as much as $840. Everyone involved already knows what the water is worth.

Who holds the cheap water โ€” 20 large corporate farms

A 2023 ProPublica and Desert Sun investigation found that just twenty large farming entities in Californiaโ€™s Imperial Valley received roughly one-seventh of the entire lower Colorado Riverโ€™s flow in 2022. That is more water than Wyoming, New Mexico, or Nevada each use in a year.

The water right itself is held by the Imperial Irrigation District, a public agency. Those entities are the largest users of that right, not its owners. As a whole โ€” historic farm families, outside investors, institutional landholders and at least one foreign hay company receives 97% of IIDโ€™s water. Every home, school and business in the county combined receives 3%.

Cheap irrigation water is not propping up the rural economy. Imperial County sits on some of the most heavily and cheaply irrigated farmland in the country, yet its per capita income in 2021 was about $19,000 โ€” half the national figure of about $38,000, according to Census Bureau estimates. It posted the highest unemployment rate in California that year.

A 2024 peer-reviewed study of agricultural water productivity across the Colorado River Basin found that the least economically productive counties consume 25% of the Basinโ€™s agricultural water to generate just 3% of its crop revenue. Heavily discounted water is not building broad rural prosperity. Where it produces high value, as in Imperial County, that value is concentrated in a small number of landholders; where it does not, it props up low-value production.

Run the counterfactual. If those same operations paid municipal-scale wholesale rates โ€” $300 to $500 an acre-foot instead of $20 to $30 โ€” the economics of growing export-bound cattle feed in a desert would collapse on their own, without a single acre-foot needing to be fought over in court. Water would move toward higher value uses because it would finally cost what it is worth. That is what a functioning price signal does. Right now, the federal government is underwriting the draining of the river for cheap crops and powerful agricultural interests.

Immediate action does not require new water-rights litigation

The most common argument against fixing this is that it would take years. Because water rights are property, this argument holds, any change must move through negotiation, buyouts, and courts.

That is true if the goal is changing who legally owns the water. It is not true if the goal is changing who pays for the infrastructure that delivers it.

Cost allocation is an administrative and budgetary process, not a property right. The Bureau of Reclamation and the Interior Department already have the statutory tools to reassess โ€œability to payโ€ determinations on a going-forward basis, to stop extending new construction-cost discounts to districts irrigating low-value forage crops, and to fully enforce the Reclamation Reform Actโ€™s full-cost pricing for large landholdings. Congress, which wrote the interest exemption into law, can require interest-bearing repayment in new and renegotiated contracts.

Those are the same terms municipal and industrial users already face. Existing repayment contracts cannot simply be rewritten in midstream; they run until they expire or are mutually amended. None of that touches a single farmerโ€™s decreed water right. It stops asking cities and power customers to keep underwriting the next generation of discounts for overuse on low-value crops.

That change would not resolve the Colorado River crisis itself. But it would start doing what a century of โ€œfirst in time, first in rightโ€ has never done: make the cost of water reflect its scarcity. It would let price โ€” not another emergency federal curtailment โ€” begin moving water toward its most essential uses.

Why hasnโ€™t it happened?

The authority sits with the Department of the Interior and the Bureau of Reclamation, which set repayment terms and administer ability-to-pay determinations under reclamation law. Legislative jurisdiction belongs to the House Natural Resources Committeeโ€™s Subcommittee on Water, Wildlife and Fisheries and the Senate Energy and Natural Resources Committeeโ€™s Subcommittee on Water and Power. Reclamationโ€™s annual budget is funded through the Energy and Water Development appropriations subcommittees in both chambers โ€” not the Interior-Environment subcommittees, whose jurisdiction excludes the Bureau of Reclamation.

The last time Congress meaningfully touched this structure was the Reclamation Reform Act of 1982. Even that act left interest-free repayment and ability-to-pay intact while expanding the size of farms eligible for subsidized water. Since then, as reservoirs have fallen toward dead pool and the federal government has spent billions on emergency conservation payments and drought relief, no bill addressing the underlying interest-free, cost-shifted pricing structure for Colorado River irrigation has reached a committee markup, let alone the floor of either chamber. A review of Congress.gov and GovTrack through August 2026 found none.

The leverage is not confined to a handful of committee chairs in Washington. It runs through the states that depend on the river. Of the 14 U.S. senators representing the Basinโ€™s seven states, seven sit on the Senate Energy and Natural Resources Committee, which has direct jurisdiction over the Bureau of Reclamation and reclamation law:

Sen. John Barrasso (R-Wyo.); Sen. John Hickenlooper (D-Colo.), also on the Water and Power Subcommittee; Sen. Mike Lee (R-Utah), committee chairman; Sen. Martin Heinrich (D-N.M.), ranking member; Sen. Ruben Gallego (D-Ariz.), also on Water and Power; Sen. Catherine Cortez Masto (D-Nev.), also on Water and Power; and Sen. Alex Padilla (D-Calif.), also on Water and Power.

In the House, 11 basin-state representatives sit on the Natural Resources Subcommittee on Water, Wildlife and Fisheries: Chair Harriet Hageman (R-Wyo.), Tom McClintock (R-Calif.), Lauren Boebert (R-Colo.), Celeste Maloy (R-Utah), Jeff Crank (R-Colo.), Melanie Stansbury (D-N.M.), Dave Min (D-Calif.), Adam Gray (D-Calif.), Luz Rivas (D-Calif.), Julia Brownley (D-Calif.) and Joe Neguse (D-Colo.). Jared Huffman (D-Calif.), ranking member of the full committee, serves ex officio.

Four basin-state members โ€” Ken Calvert (R-Calif.), Celeste Maloy (R-Utah), Mike Levin (D-Calif.), and Susie Lee (D-Nev.) sit on the House Appropriations Subcommittee on Energy and Water Development, which writes Reclamationโ€™s budget every year.

According to the same review, none of these lawmakers, of either party, has introduced legislation addressing the interest-free, ability-to-pay repayment structure at the center of this piece. The people with the most direct stake in the outcome โ€” whose constituents are either the cities paying full price or the districts paying a fraction of it โ€” already hold seats on every committee with the authority to change it.

The hard conclusion

This complicated system of senior rights and subsidies, built and protected for a hundred years, leads to an unavoidable conclusion. Under the banner of property rights and support for agriculture, we have allowed a small number of large, politically connected agricultural users to capture much of the water that forty million people depend on.

Almost half of the water put to human use across seven states, from the high Rockies to California, has been turned to private benefit for irrigation of low-value crops, to the detriment of everyone else in the region. Having secured water rights at no cost and federal infrastructure at a steep discount, those same users are demanding to be paid top dollar โ€” more than $800 an acre-foot โ€” to leave that water in the river.

None of this is a call to end Western agriculture or to strip farmers and ranchers of property they hold in good faith. It is a call to stop asking the public to underwrite, at steadily mounting costs, a pricing structure that a small number of landholders have had a century to defend and a well-organized lobby to protect. The technical authority to change the next round of contracts and ability-to-pay reviews already exists inside agencies Congress funds every year. Using that authority still takes political will the basinโ€™s own delegation has not yet shown.

Taking on powerful agricultural interests requires action from representatives of the forty million people who need a sane and sustainable water policy.

Denver Water to reduce Fraser River flows amid extreme #drought — The October 13 reduction will lower #FraserRiver flows to 2 cubic feet per second as Denver Water responds to drought and systemwide water shortages — Sky-Hi Daily News

Grand County residents will see considerably less water flowing down the Fraser River starting Oct. 13th. Denver Water typically diverts water from the Fraser River through the Moffat Tunnel to serve customers during the winter, according toย Trout Unlimited. But because of extreme drought conditions caused by a lack of snowpack and record-high temperatures, the Fraser River has considerably less water to give…

Since 1969, Fraser River flows have been required to maintain a minimum of 4 cubic feet per second, or cfs, when Denver Water diverts water, a requirement tied in part to U.S. Forest Service requirements. Now, Denver Water is reducing Fraser River flows to 2 cubic feet per second starting Oct. 13 to accommodate extreme drought conditions, according to a Denver Water email forwarded to Sky-Hi News. Reductions remain in place until May 15, unless drought conditions improve or if Denver Water encounters โ€œunforeseen operational issuesโ€ that require them to increase reductions, according to Denver Water Communications Manager Travis Thompson, in an email to Sky-Hi News. Along with reducing Fraser River flows, Denver Water will reduce flows in its tributaries; Vasquez Creek and St. Louis Creek will be reduced to 2 cfs, and Ranch Creek to 1.5 cfs, according to the Denver Water email andย Kirk Klancke, president of the Colorado River Headwaters Grand County Chapter.

September 9, 2026

For more than the last century, the flows of the Colorado River have been managed and dictated by the demands of a rapidly growing and changing West. There are founding legal documents, and then agreements stacked on those, often known as the โ€œLaw of the River.โ€ These agreements are between states, between sovereign nations, including Tribal Nations and Mexico; between districts and companies and branches of the US Government. Itโ€™s hard to find the appropriate metaphor for how all of these agreements work together (and at times against one another) to manage the Colorado River system. But even fraught metaphors are sometimes the only way to get through something so complicated.

Imagine the web of agreements and founding legal documents that guide the management of the Colorado River as a body. The 1922 Colorado River Compact would be the skeleton, the framework upon which all the other functions of the body are built. The limbs could be the communities, farms, Tribes, businesses, ecosystems, and economies that rely on the riverโ€™s blood (Colorado River water).  The agreements that build on the framework of the Compact, such as the 2007 Interim Guidelines or the 2019 Drought Contingency Plan (DCP), act as nerves that facilitate or trigger movement and action. Perhaps the brain is the network of decision makers โ€“ the Bureau of Reclamation, the states, the Tribes, Mexico and others whose decisions and cooperation keep the system functioning, underscoring why coordination and consensus are so important: a body whose different parts are working at cross-purposes cannot function effectively. The blood then, of course, is the Colorado River water allocated to parts of the body. 

Continuing the body metaphor for the contemporary management of the Colorado River system, additional agreements (or the nerves that trigger certain action) were added to the body.

Colorado River, Colorado | Trout Unlimited Joshua Duplechian

On Friday, August 24, the Bureau of Reclamation released three documents outlining a 10-year framework for how the Colorado River will be managed for the next two years and how management decisions for the subsequent 8 years will be made. You can read the Bureauโ€™s summary doc here.

  1. Theย Final Environmental Impact Statement (FEIS): evaluates the many proposed plans Reclamation considered for how the river should be managed going forward, and identifies a preferred alternative, a 10-year framework built on operating plans developed in at least two-year increments;
  2. Theย Record of Decision (ROD): adopts the 10-year operating framework and sets the principles and guardrails for future operations including how water can be stored, shortage sharing, critical infrastructure protection, consultation, and the movement of water between Lake Powell and Lake Mead; and
  3. The 2027-2028 guidelines:ย establish the specific operating approach for the first two years under the new framework.

While the two-year guidelines put real numbers and real movement on the table, the ultimate test is whether the guidelines, alongside the side agreements, investments, and management tools needed to support them, are put in place and function as intended โ€“ and whether, together, they can keep the body upright.

Six months from now, the more consequential questions will be whether the new guidelines:

  • provide more certainty and transparency, including clear pathways for addressing disputes and disagreements when they arise;
  • supportย flexible and adaptive management toolsย that can respond to changing hydrology and conditions;
  • meaningfullyย include Tribal Nationsย in both decision-making and implementation;
  • reduce reliance on emergency operationsย and short-term crisis response; and
  • create aย workable path toward long-term resilienceย โ€” one that can withstand disagreement, including litigation, without bringing implementation and collaboration to a halt.

Finally, and critically, these new guidelines must recognize healthy rivers and watersheds as a core element of the Basinโ€™s resilience infrastructure, because in the middle of all the agreements โ€“ at the core of all the collaboration and controversy, the skeleton and nerves and muscles that move it, there is a river โ€“ there is a heart; the whole reason blood moves through the system at all.

Healthy rivers and forests, connected floodplains, and intact watersheds are essential to the body, to the Basin. They support the reliability of our water supplies, reduce the risks and impacts of wildfire; they sustain fish and wildlife, support recreation, and strengthen the Basinโ€™s ability to withstand drought and changing conditions. They are invaluable.

Which is to say, at the center of all the agreements and negotiations and collaboration and controversy, is the river. Has always been the river. And if we succeed at all in our management, if we have any hope of keeping this body upright, there will always be the river.

#Utah is paying farmers to conserve #ColoradoRiver water. Is it working? — The Salt Lake Tribune #COriver #aridification

The Colorado River flows through seven states and provides water to 40 million people. Photo credit: USBR

September 30, 2026

Utah is betting that voluntary conservation like this can help protect the state as the Colorado River shrinks and the seven states that depend on it fight over who should use less. 

โ€œWe want to develop a block of water in Powell with Utahโ€™s name on it, so if we have to do mandatory curtailment, thatโ€™s the first block of water that we have to use to meet that demand,โ€ [Kent] Stilson said…

Those states โ€” Arizona, California and Nevada โ€” and Upper Basin states โ€” Colorado, New Mexico, Utah and Wyoming โ€” have been in tense negotiations about how to share the diminishing Colorado River. With no deal reached, the Bureau of Reclamation moved forwardย with a plan that requires the Lower Basin to conserve 1.25 million acre-feet of water next year, with steeper cuts possible in the future.ย  The plan includes no mandatory cuts in the Upper Basin, just a goal to conserve 200,000 acre-feet per year. Given the Upper Basinโ€™s limited conservation in the past, thatโ€™s a โ€œvery ambitious goal,โ€ said Eric Kuhn, retired manager of the Colorado River Water Conservation District. The burden of conservation has been a major sticking point among the states: if the Lower Basin has to take cuts, those states want the Upper Basin to commit to measurable conservation. But Utah and its neighbors argue that Mother Nature already forces shortages in dry years. If states canโ€™t agree, the Lower Basin could sue the Upper Basin over the Colorado River Compact in an attempt to force cuts to water use. So Utah is preparing. By paying water users to temporarily send water downstream, itโ€™s hoping to bank credit to pay for future cuts.

September 30, 2026

Anyone can see that something is deeply wrong at Blue Mesa Reservoir on the Western Slope. Itโ€™s historically been the biggest body of water in the state. But not anymore.ย  The deep,ย long-lasting droughtย has shrunk it so much it lost that title to Lake Granby up north. Now it looks like someoneโ€™s opened the drain on a gigantic, rocky bathtub, with only a bit of shiny blue water pooled at the bottom…For 60 years, Blue Mesa Reservoir has stored water that flows to communities and generates electricity. Itโ€™s also a popular recreation spot, a 20-mile-long lake sandwiched between Montrose and Gunnison. Growing up on the edge of this vital water source, Riser has watched decades of visitors bobbing on their motorboats and jet skis, with their coolers and kids, dogs and music…Del Piccolo said heโ€™s never seen algae โ€œthat blue and vibrant.โ€[…]The neon-blue algae is like a warning sign of just how bad things are at Blue Mesa. There are actual warning signs posted, too, saying the water is now dangerous to people and pets. Sonja Chavez, executive director of the Upper Gunnison River Water Conservancy District, thinks itโ€™s the worst Blue Mesa has ever looked…

Colorado SNOTEL basin-filled map May 31, 2026.

Blue Mesa is not a naturally occurring lake but instead is man-made, designed by the federal government to store water for downstream communities, farms and ranches. It also generates electricity and is federally mandated to release water that provides habitat for threatened and endangered fish, including the nativeย razorback suckerย andย humpback chub. Federal officials take all of that into consideration when they determine how much water to discharge. This year, they were faced with an abysmal snowpack โ€” that accumulation of snow that builds up throughout the winter. Chavez believes the U.S. Bureau of Reclamation, which controls how much, and when, water flows out of Blue Mesa, needs to adjust more quickly to lean water years like this one.

Chavez thinks the BoR was releasing too much water too early in the season, which drove Blue Mesa into crisis.ย  In an email statement, the agency said it does work from 24-month forecasts of how much water will melt into reservoirs, but that it also adjusts water releases as conditions change.

โ€œMoving forward, Reclamation is already working with our forecasting partners and water users on ways to improve modeling for dry year water use, enhance forecasting โ€ฆ and review historic operations to identify opportunities for increased drought resiliency,โ€ said Bart Deming, BoR Western Colorado Area office manager.

What if? What would a #ColoradoRiver Compact Call mean for #Colorado? A significant Compact tripwire may hit next month and the Lower Basin States might take the Upper Basin States to court — Ken Neubecker (Ken’s Substack) #COriver #aridification

September 16, 2026

Walter and I frequently walk along the Colorado River in Glenwood Springsโ€™ Two Rivers Park, where the Roaring Fork joins in. The Colorado has been running reddish brown lately due to some intense rain and blowouts from small tributaries upstream, gullies that normally are dry. Not this summer. The Roaring Fork runs clear, creating a distinct division between the flows, a narrow ribbon of clear cold water that runs alongside the warmer and muddier stream for a long ways before they mix.

Both streams and most others are extremely low, even for late summer. Many of the USGS gauges have exclamation points next to them on the map, meaning โ€œextremely below averageโ€. There are rocks exposed to the air that Iโ€™ve never seen before. What little monsoon rain we had didnโ€™t do anything, not even for the dry soils that will likely soak up much of the snow melt next spring before it can reach the rivers.

Years ago when Iโ€™d go to water meetings and conferences, back when people referred to our current situation as an unusually long drought, there was some talk about the Colorado River Compactโ€™s requirement that the Upper Basin not cause the river flow to drop below 75 million acre feet (maf) over a ten year running average. Oh, weโ€™ll see that train wreck coming with plenty of time to do something, they all said. That train wreck is now happening. The engine is sliding over the cliff as the States argue about the menu back in the dining car. All that really happened was serious can kicking along the tracks.

The first Upper Basin โ€œtripwireโ€ of 82.5 maf, the 75 maf plus 7.5 maf for Mexico could come as soon as next month. Now the can being kicked is full of lawyers.

So, what does the 1922 Compact actually say? The meat is in Article III:

This is what each basin could expect every year.

This is where the additional 1.5 maf per year, split as 750,000 acre feet due from each basin comes in. There was no agreement on Mexicoโ€™s share of the river in 1922, or in 1928 when the Compact was finally ratified. That came in 1944 with a formal treaty regarding Mexicoโ€™s share in both the Colorado and Rio Grande Rivers. The Compact negotiators anticipated such an agreement, hence paragraph (c). What they didnโ€™t anticipate were decades of no โ€œsurplusโ€. Thatโ€™s another story.

The more serious tripwire comes next:

October 1, 2026, may well see the flow at Lee Ferry cross the first line in the sand of a dry riverbed if the ten year running average drops below 82.5 maf for the first time since Lake Powell began filling. Back then water was held in the new reservoir to fill it. Everyone was OK with that. The Colorado River flows upstream were still quite robust on average and Lake Mead had plenty to satisfy the Compact requirements for the Lower Basin and Mexico as Powell filled.

Not anymore. Powell is shrinking rapidly. As of this writing the reservoir is at just under 22% full, and only about 27 feet from the elevation where the dam can no longer run water through the power plants penstocks. And the outflow is still about twice the inflow.

The monsoon rains turning the river reddish brown in Glenwood wonโ€™t help.

So what happens if that 82.5 maf tripwire is triggered and one or more states of the Lower Basin place a Compact Call?

Itโ€™s complicated.

It would mean a lawsuit between the states, which would go straight to the US Supreme Court. No lower courts would be involved, and it could take years to resolve. The last time there was a lawsuit about Colorado River apportionment it was between Arizona and California. The case was filed in 1952. The Court appointed a Special Master to work it out and recommend a solution. That took ten years. The case was finally argued in the Court in 1963, with a final decision handed down in 1964. That decision finalized the legal structure for allocations in the Lower Basin, based on the 1928 Boulder Canyon Act.

Twelve years for a resolution. We donโ€™t have that much time for any new case on the Colorado River, especially with how the Upper Basin might comply with Article III, paragraph (d), and Mexicoโ€™s share thrown in.

In 2018 and 2019 the Colorado River Conservation District (River District) commissioned a risk study to look at how flows might augment storage in Lake Powell as well as what might happen should Lake Powell ever reach a level where Compact deliveries dropped to a point where the 82.5 maf over ten years wasnโ€™t met, causing a Compact Call. It was, in light of todayโ€™s situation and the worsening hydrology, a tad optimistic. The first point in the Executive Summaryโ€™s Takeaway states:

The critical low level used for the analysis was 3525 feet, the Bureau of Reclamations critical low as well. Today, September 16, 2026, the elevation at Glen Canyon dam is just under 3517. It continues to drop every day, counting down to October 1.

If the Lower Basin states place a Compact Call it very well could be โ€œcatastrophicโ€ for water users in the Upper Basin. But there are scenarios where it could be less so. At the very worst all diversions junior to November 24, 1922, or possibly June 25, 1929 when the Boulder Canyon Act was signed, would be curtailed, cut off, until the Compact deficiency is resolved. But that truly is a worst case scenario.

Curtailment would likely be based on what the flow deficit is at Lee Ferry when the call is placed and what increase through Upper Basin curtailment might make up the deficit. Diversions could be cut on a sliding scale, with the most junior taking the biggest hit, going back from today to that date in 1922 or 1929. We wouldnโ€™t probably notice much at first as October 1, the start of the new water year, coincides pretty closely with the end of the irrigation season for most.

Colorado transmountain diversions via the State Engineer’s office

The River Districts study looked at various scenarios for Colorado, based on appropriation dates, river basins vs entire West Slope, and amounts of water that might be needed to satisfy the deficiency at Lee Ferry. The biggest hits would be in the Colorado River mainstem, especially with the large trans-mountain diversions taking water to Eastern Slope cities and farms. The Front Range cities, where most of Coloradoโ€™s population resides and who rely on as much as 50% or more of their water supply coming from the Colorado River, along with the significant agricultural areas along the South Platte and Arkansas Rivers, could see some pretty significant cuts regardless.

The State, through the Colorado Water Conservation Board (CWCB) and Attorney Generalโ€™s office did a Compact compliance study some years ago but is keeping that confidential. I canโ€™t blame them. It could become a basis for court arguments and negotiations should a compact call become a reality. The River District study could be as well. Itโ€™s worth a read if you are really interested in all this, and anyone who uses water in Colorado, East or West, to fill a tea pot from the faucet, flush a toilet or raise crops should be. They River District study can be found here or on their website.

Monsoonal moisture is still floating water laden clouds over us today, and some have dropped a good bit of rain. But that wonโ€™t help much. We are facing a โ€œsuper El Ninoโ€ this winter, which may or may not provide a healthy snowpack. Anything would be better than last winter, except a repeat of that dry season. In any case it will take many years of โ€œnormalโ€ snowfall to begin to refill the reservoirs. Given the trend of aridity and climate warming that is not something we should be counting on.

Perhaps, hopefully, the most important part of the compact written at the beginning will be called upon:

Of course the rub here will be in how โ€œequitable divisionโ€ is defined, and I imagine this could take much of the courts time in a Compact Call. In 1922 that meant an equal share of the rivers water for each basin. Now it could hinge on where the greater โ€œvalueโ€ is, and what that means. Back in 1922 โ€œbeneficial usesโ€ were pretty straight forward. Now there are many more uses of the river deemed โ€œbeneficialโ€.

The needs and values today are quite different from what they were 104 years ago. The Tribes, the environment, recreation, local economies and traditions. All were either excluded in 1922 or covered by broad undefined ambiguity. Climate change wasnโ€™t heard of, even though some scientists at the time had warned about it.

Itโ€™s a brave new world we are entering. Business as usual based on a 104 year old piece of paper and the other paper agreements founded on it wonโ€™t help us adapt to that world, nor will wishful thinking and other optimistic dreams based on hope. As Brad Udall noted during a recent PBS Newshour Tipping Point presentation, we need to re-think the whole thing. It wonโ€™t be easy, but as Udall pointed out it could be good. We need to rethink both what the river can provide and the reality of adapting to that. We also need to rethink the โ€œvaluesโ€ we base our water needs on. Itโ€™s not just about endless economic growth anymore. Throwing lawyers at each other only enriches lawyers while it impoverishes us.

Meanwhile Walter and I will continue our ramblings with the river. Weโ€™ll also stop by the River District offices to say hi to the many friends there, to add some stress relief and try to keep their heads from graying any faster than they already are.

โ›ˆ๏ธ WACKY WEATHER WATCHโšก๏ธ

Welcome to another edition of the Land Deskโ€™s NEWSWIRE, and yet another one in which the big news is the big, end-of-the-water-year rain. Yes, 88% of the Western U.S. is currently experiencing some level of drought โ€” with the most severe impacts in the Four Corners Country. Yet these same areas have also been barraged with rain and inundated with flood watches and warnings for the last few weeks, and yet another big doozy is on its way.

As of Monday morning (9/28), all of New Mexico, most of Arizona, and southern Utah and southern Colorado were all under a flood watch in effect through Wednesday morning. The National Weather Service is warning that rainfall rates in some places could be up to one to two inches per hour.

The latest round of storms will hit already sodden ground in places that have received more rain in the last couple of weeks than they normally do during the entire monsoon season.

A new legal path for stream restoration in #Colorado runs into old water conflicts: Projects repair degraded headwaters, but downstream users have concerns — Heather Sackett (AspenJournalism.org)

September 30, 2026

After the 2020 Pine Gulch Fire scorched 95,000 drought-stricken acres of High Lonesome Ranch in Garfield and Mesa Counties, the rainstorms that followed eroded hillsides and washed mud and rocks into the Dry Fork Creek valley bottom.

โ€œIt was a major impact to operations here,โ€ said High Lonesomeโ€™s General Manager Travis Brooks. โ€œThe wildlife habitat obviously was erased, populations disappearedโ€ฆ The flooding, the debris flows, the devastation that comes after the fire is almost as bad as the fire itself and weโ€™re still seeing the effects of that.โ€

Brooks has overseen work to repair the riparian corridor and control erosion; now the area is green and wildlife โ€“ including beavers โ€“ have returned to the watershed. The areaโ€™s recovery is due, in part, to a piece of 2023 legislation that cleared the way for minor stream restoration projects in Colorado. High Lonesome Ranch is the site of one of the first of these types of projects completed since the passage ofย Senate Bill 23-270.

In 2023, Colorado lawmakers recognized the need to restore the environmental health of the stateโ€™s waterways, especially after wildfires. The legislation allows minor stream restoration projects to take place without being subject to water rights administration, provided they meet certain criteria. But this is uncharted legal territory and early projects are highlighting old tensions between water rights holders and proponents of stream restoration.

The Dry Fork Creek project, which is wrapping up its third and final year of work on High Lonesome Ranch, was spearheaded by Audubon Rockies. 

Over three years, crews installed about 200 simple, porous structures over two miles of stream, with the goal of trapping sediment, slowing the flow of water, raising the water table and rewetting the sponge of the floodplain. The structures, sometimes called Beaver Dam Analogues for the way they can mimic beaver activity, are built by weaving willows and tree branches across the channel between posts hammered into the streambed. 

The official name for these low-tech, process-based restoration methods is Post-Assisted Log Structures, and they can turn a deeply incised, V-shaped stream with steep banks into a wider, gently sloping, U-shaped streambed. The structures act as speed bumps for the torrents that wash down the valley during summer storms and can improve watersheds that have been degraded by fire as well as human activities like road building and cattle grazing.

โ€œI really do believe that weโ€™re improving the water quality out here by doing this work, which is helpful to everybody downstream,โ€ Brooks said. โ€œI think thatโ€™s the biggest takeaway.โ€

On a sunny day in late September, Abby Burk, Western Rivers program director for Audubon, led a tour of the flagship project, showing how stream restoration is put into practice under the new legislation.

โ€œAll of these different types of structures are really looking at arresting sediment, holding sediment, spreading water on the landscape and slowing it down so that we can have a bit more of a connected floodplain,โ€ Burk said.

Putting policy into practice

Senate Bill 23-270 allows for six categories of minor stream restoration activities, such as stabilizing the banks or reconstructing a channel of a natural stream system. If a project falls under one of the six categories, it is presumed to not harm other water users and can move forward with little scrutiny from state officials.

Environmental groups that worked on the legislation had originally wanted to set a size standard for stream restoration based on the historical footprint of the floodplain before it was degraded. But opponents, some of whom were agricultural water users, argued this area was too large and ill-defined, and floated the idea of placing a cap on how much new surface area of water that projects were allowed to create. Their concern was that projects could create more surface area for evaporation and reduce streamflows. 

Thatโ€™s a problem because in Coloradoโ€™s system of water law where the oldest rights get first use of rivers, water is usually already spoken for by someone downstream. Without SB 270, stream restoration proponents could have to go through an expensive and lengthy process to buy into an augmentation plan, which replaces the water consumed by evaporation.

The final bill represented a compromise between the two sides, and required that these minor restoration projects donโ€™t back up water past the โ€œordinary high-water markโ€ of the stream. 

โ€œI think this is an elegant compromise,โ€ said Burk, who helped shape the bill. โ€œWe landed at a bipartisan solution that was unanimously supported.โ€

Immediately after the passage of the bill, stream restoration proponents were disappointed in the final version. But in the three years since, SB 270 seems to be providing the necessary legal and political cover for groups to move forward with low-tech, process-based projects, with several underway on the Western Slope. 

โ€œWe started taking more time to process it and read it, and then we actually realized, you know, I think we actually got something pretty good here that weโ€™re going to be able to do some great stuff with,โ€ said Jackie Corday, a natural resources consultant who worked on the bill and the Dry Fork Creek project.

Downstream conflicts

As more groups take on projects under SB 270, it means the bounds of the legislation will be tested as potential conflicts arise with downstream water users.

On a Saturday in late August, the National Forest Foundation and Roaring Fork Outdoor Volunteers kicked off another restoration project, installing about 40 PALS in the White River National Forest in the headwaters of Middle Thompson Creek, a tributary of the Crystal River. The area was identified as a prime spot for stream restoration in a beaver inventory conducted in 2023 and 2024 by the U.S. Forest Service and funded by Pitkin County.

โ€œIdeally, the changes in the channel that these [structures] provoke, and the changes in the vegetation will be enough to make those areas attractive to beaver again and beaver will just recolonize the site,โ€ said Clay Ramey, a fisheries biologist with the White River National Forest.

The Forest Service is planning another, similar project next year in the headwaters of Four Mile Creek, one drainage over from Thompson Creek. But the size and scope of the proposed project has raised concerns from a local water conservancy district. The Rifle-based West Divide Water Conservancy District owns several small reservoirs and provides supplemental irrigation water and augmentation water for domestic water users.

West Divide says the project could impact water supply for its planned expansion of Martin Reservoirs. It contends the work would increase both the surface area of the stream, which causes evaporation, and the water consumed by wetland vegetation.

In a January letter to the state Division of Water Resources Division 5 Engineer Tyler Benton, the conservancy district said that the 152 structures planned over three phases is outside the scope of what is allowed by SB 270 and asks state officials to assess the projectโ€™s potential for injuring water rights holders. 

โ€œItโ€™s not the healthiest stream by any stretch and so some restoration efforts are in order,โ€ said West Divide board member Chris Treese. โ€œBut we donโ€™t want those efforts to result in an impact to our water rights or any other water rights downstream that are within the West Divide district.โ€

More data needed

Part of the source of the disagreement comes from a lack of data about how exactly these types of projects that mimic beaver activity influence how water moves through valley bottoms. 

Joel Sholtes, a water resources engineer and instructor at Colorado Mesa University, is aiming to answer that question. In August he was awarded a three-year $15,000 grant from Pitkin County Healthy Rivers to study how beaver activity alters ecosystems in the North Thompson Creek area. The sites with beavers can be a reference point to compare with areas restored by humans. 

Sholtes will take seasonal measurements to try to better understand how much water beaver ponds detain, how it changes throughout the year and the differences in stream conditions between areas with resident beavers and those without. Sholtesโ€™ early findings on a long-term study of headwaters across the state show that restoration projects do not produce large or sustained reductions in streamflow.

โ€œThe evolution and passing of SB 270 became contentious, and that conversation brought to bear a lot of knowledge gaps that we have related to stream restoration in headwaters,โ€ Sholtes said. โ€œThereโ€™s just not a big, robust body of literature, so the studyโ€™s number one effort is to address that in whatever ways we can. Itโ€™s not going to answer the question definitively, but itโ€™s going to bring more data and nuance to the conversation.โ€

The Forest Service is monitoring and measuring the streamflows at the Four Mile project site to see what they are dealing with and the effects of their work โ€“ information West Divide is also interested in โ€“ with the intention of installing the first structures next summer.

For now, Burk says SB 270 is a good tool to accomplish 75% to 80% of the stream restoration projects that happen in Colorado. Most of these fall under three of the legislationโ€™s six categories: stabilizing the streambanks with natural materials that allow water to flow downstream and donโ€™t back up water past the ordinary high-water mark; stabilizing an intermittent stream by installing porous structures into the banks; and installing structures or reconstructing a stream channel for recovery from a wildfire or flood. 

โ€œThis was designed for a subset of projects that are the majority to go forward because of the ecological and community benefits and watershed benefits,โ€ Burk said.

A working group led by Burk and Corday has also created a training manual for best practices that groups can use to make sure their projects stay within the bounds of SB 270.

Communication with DWR essential

So what happens when restoration proponents believe their project fits within these parameters, but downstream water users argue the project goes too far? 

Division of Water Resources officials have a limited role in refereeing these types of disagreements. Project proponents are not required to get approval from state officials and state officials do not have the authority to approve or deny projects. But as the administrator of the stateโ€™s water rights, DWR officials could still force a project to be removed if they determine it is harming downstream water users or require the project to get an augmentation plan from a water court that replaces the water it uses. 

In the case of the Four Mile project, Division 5 Engineer Tyler Benton wrote in a February letterto Ramey that he does not have sufficient information to determine if the project would harm downstream water users, but that the Forest Service should communicate with the local DWR water commissioner to ensure the project complies with the law.

Both Burk and Ramey stressed the importance of communication and transparency with DWR officials to ensure the projects are in compliance with SB 270 from the beginning. Ramey said the water commissioner has visited both the Middle Thompson and Four Mile sites and is familiar with the projects. 

Back at High Lonesome Ranch, beavers have moved back into the restored area and created ponds, amplifying the humansโ€™ restoration work. Brooks said the project fits with the ranchโ€™s philosophy of conservation and regenerative ranching, and he has aspirations of doing more work to revitalize the propertyโ€™s other fire-damaged drainages in the future.

โ€œThe beaver activity that we saw is a big indication that weโ€™re doing something right,โ€ Brooks said. โ€œWildlife are coming back and utilizing the space the way a healthy riparian system should be utilized.โ€

โ›๏ธ MINING MONITOR โ›๏ธ

The mining claim game continues to heat up in the areas Trump illegally slashed from Bears Ears National Monument, and the top player is, once again, Kimmerle Mining of Moab. Since the Land Desk last wrote about this mini-land rush, Kimmerle has filed seven additional claims areas that had been within the national monument, and therefore off limits to new mining claims.

The latest claims are in the White Canyon area. During the post-War uranium frenzy, the federal government, county crews, prospectors, and mining companies webbed this area with roads, poked it full of prospect holes and mine adits, and contaminated waters with radioactive materials. Part of that legacy includes a 26,000-ton pile of uranium tailings entombed within the waters silt of Lake Powell.

Itโ€™s important to keep in mind that the presence of active mining claims does not necessarily mean anyone is going to mine or even explore these pieces of land. And while the claims may be active, which simply means the claimant is up to date on their $200/year location and maintenance fee, they may not be valid. That requires, at least theoretically, proof that the claim contains valuable minerals.

But it does appear as if Kimmerle is targeting viable mining areas, which indicate that the firm either intends to mine the claims, or consolidate enough of them to sell them to a larger company. The newly revealed claims are located in two clusters on either side of Natural Bridges National Monument.

The notices of location have been declared with the San Juan County Recorder, but have not yet shown up on the Bureau of Land Management database. Just before publishing this, I checked the San Juan County records search and found that an entity called Land Survey Advisers โ€” which typically stakes claims for other firms or individuals โ€” filed location notices on more than three dozen claims in San Juan County. At least some of those claims appear to be within the pre-shrinkage BENM boundaries, but the location description on many of them included sections that donโ€™t exist (43, 47) in the public land survey system, and the document download function isnโ€™t working for me, so I have yet to confirm any of this. Still, itโ€™s potentially alarming.

The Kimmerle claims include: 

  • Six lode claims (each at 20.66 acres) on the north slope of the Tables of the Sun formations in the upper Fry Canyon drainage, just on the boundary line of the original Bears Ears National Monument. While this specific area has seen little mining activity in the past, it is in the same vicinity as the Daneros Mine, which was up for expansion as recently as 2016. And the new claims are adjacent to Kimmerleโ€™s Lucky group of claims.ย 
    The nearest historic mining activity was at theย Fry # 4 mine1, an underground uranium mine with over 400 meters of workings. In 1977, the operator was Utah Power & Light Co., which was the main mining company of the area at the time.
  • One lode claim on the east slope of Upper Lost Parks, an appendage of Elk Ridge just north of Natural Bridges National Monument and south of the Woodenshoe formation. Itโ€™s across Deer Creek Canyon from Kimmerleโ€™s Geitus and Cedar claims, which the firm staked just before President Barack Obama designated Bears Ears, and right after President Donald Trump shrunk the monument for the first time. Itโ€™s also in the vicinity of the Sandy claims that Kimmerle held, but that [those?] were closed in 2015. The area was mined and prospected heavily during the Cold War. The nearest historical mines and prospects were the Big Red, the Sandy, and the Hideout. In 1977, the Big Red โ€” operated by Utah Power & Light โ€” was reported to have a flooded, a caved, and an open adit. While the Hideout sparked a 1950s prospecting boom in the area, none of these were ever large producers. However, a 1965 USGS report did indicate this part of Elk Ridge was favorable for uranium deposits, which is likely one reason the Trump administration stripped it of national monument protections.

The White Canyon area was known to contain rich uranium reserves back in the 1940s and 1950s, but its remoteness and the rugged landscape created challenges for mining companies looking to exploit the resources. One of the biggest hurdles was getting the ore to the Monticello processing plant, which required driving gnarly roads across the crinkled landscape and up and over Elk Ridge.

So in 1949, the Vanadium Corporation of America built a small mill at theย confluenceof White Canyon and the Colorado River, primarily to process uranium ore from the nearby Happy Jack Mine, located upstream in the White Canyon drainage (and just within the original Bears Ears National Monument boundaries). For the next four years, the mill went through about 20 tons of ore per day, crushing and grinding it up, then treating it with sulfuric acid, tributyl phosphate, and other nastiness. One ton of ore yielded about five or six pounds of uranium, meaning that each day some 39,900 pounds of tailings were piled up outside the mill on the banks of the river.

In 1953 the mill was closed, and the tailings were left where they sat, uncovered, as was the practice of the day. Ten years later, water began backing up behind the newly built Glen Canyon Dam; federal officials decided to let the reservoirโ€™s waters inundate the tailings. There they remain today, though at current lake levels they are probably buried by and mixed in with the Dominy Formation of silt, rather than covered with water.

During the uranium days of the West, more than a dozen mills โ€” all with processing capacities at least ten times larger than the one at White Canyon โ€” sat on the banks of the Colorado River and its tributaries. Mill locations included: Shiprock, Mexican Hat, Monument Valley, Tuba City, Monticello, Rifle, Grand Junction, Moab, Uravan, Green River, and Naturita. There was even an ore upgrading mill at Fry Canyon, followed by a copper heap leaching operation. Groundwater contamination continues to today, and was partially responsible for the Fry Canyon Lodgeโ€™s demise.

At the Durango mill the tailings were piled into a hill-sized mound just a stoneโ€™s throw from the Animas River. They werenโ€™t covered or otherwise contained, so when it rained tailings simply washed into the river. Worse, the millโ€™s liquid waste stream poured directly into the river at a rate of some 340 gallons per minute, or half-a-million gallons per day. It was laced not only with highly toxic chemicals used to leach uranium from the ore and iron-aluminum sludge (a milling byproduct), but also radium-tainted ore solids.

Radium is a highly radioactive โ€œbone-seeker.โ€ That means that when itโ€™s ingested it makes its way to the skeleton, where it decays into other radioactive daughter elements, including radon, and bombards the surrounding tissue with alpha, beta, and gamma radiation. According to the Toxic Substances and Diseases Registry, exposure leads to โ€œanemia, cataracts, fractured teeth, cancer (especially bone cancer), and death.โ€

It wasnโ€™t any better at any of the other mills. In the early 1950s, researchers from the U.S. Public Health Service sampled Western rivers and found that โ€œthe dissolved radium content of river water below uranium mills was increased considerably by waste discharges from the milling operationsโ€ and that โ€œradium content of river muds below the uranium mills was 1,000 to 2,000 times natural background concentrations.โ€

That was just from daily operations. In 1960, one of the evaporation ponds at the Shiprock mill broke, sending at least 250,000 gallons of highly acidic raffinate, containing high levels of radium and thorium, into the river. None of the relevant officials were notified and individual users continued to drink the water, put it on their crops, and give it to their sheep and cattle. It wasnโ€™t until five days later, after hundreds of dead fish had washed up on the riverโ€™s shores for 60 miles downstream, that the public was alerted to the disaster.

Of course, whatโ€™s dumped into the river at any of these places doesnโ€™t stay there, but makes its way downstream. In the early 1960s, while Glen Canyon Dam was still being constructed, the Public Health Service folks did extensive sediment sampling in the Colorado River Basin, with a special focus on Lake Meadโ€™s growing bed of silt, which had been piling up at a rate of 175 million tons per year after Hoover Dam started impounding water in 1935. The Lake Mead samples had higher-than-background levels of radium-226. The report concludes:

And so, the billions of tons of silt that has accumulated in Lake Mead and Lake Powell serve as archives of sorts. They hold the sedimental records of an era during which people, health, land, and water were all sacrificed in order to obtain the raw material for weapons that are capable of destroying all of humanity. If the new mining claim mini-rush is any indication, some more records may be added to the archive before long.

Anna Vargas noted it first. There was more water in La Jara Reservoir on Saturday than when she had been weeks earlier. That in itself was a blessing.

Then there was the discovery of a piece of volcanic glass obsidian by Loretta Mitson that excited the group, along with evidence of a habitation site lord knows how many thousands of years ago just above the thin reservoir.

Vargas and Mitson were part of a caravan of conservationists, archeologists and public officials who took a field trip to mark National Public Lands Day in the La Jara Basin.

They had another purpose as well.

Back in November 2025, the Colorado State Land Board voted to transfer ownership of the La Jara Basin property to a trio of public agencies โ€” Colorado Parks & Wildlife, U.S. Forest Service and U.S. Bureau of Land Management โ€” through a $49.5 million transaction funded through federal tax appropriations, state tax dollars and money from agencies like Colorado Great Outdoors.

Vargas and her boss, Chris Canaly, executive director of San Luis Valley Ecosystem Council, organized the outing that brought along Mitson, one of the Valleyโ€™s noted historians; Colorado State Sen. Cleave Simpson; Saguache County Commissioner Tom McCracken; and Mick Daniels and Estaban Salazar from San Luis Valley Great Outdoors, among others, to put attention back on the transaction. The expectation is that the thousands of pages of paperwork involved will be signed, money transferred, and the deal finalized by yearโ€™s end.

โ€œWe are setting the table for what is going to be happening, we hope soon,โ€ said Canaly, promising a grand event for next summer when all the paperwork is complete.

State Land Board office manager Jenny Minich told Alamosa Citizen that a more definitive update on the closure of the transaction should be available in the next couple of months.

โ€œI think itโ€™s going to be quite a wonderful gathering,โ€ said Canaly in anticipation of the finality of the deal and a celebration of the La Jara Basin to come.

How the La Jara Basin ended up in the hands of the state of Colorado is unique. Then how the state through its land board eventually came around to transferring ownership to federal partners and Colorado Parks & Wildlife rather than sell the land holdings to a private party is another tale.

โ€œThis property is really unique within their ownership because when states would come into being, the federal government would deed them a certain amount of land in every township and they were supposed to use those lands to raise money for schools in the frontier states,โ€ said Allen Law of Western Rivers Conservancy, who joined the public lands day trip. 

โ€œAnd how La Jara came to be is, some of those sections that should have been state sections were already homesteaded or they were on reservation lands or treaty lands or things like that. So those sections werenโ€™t available. The federal government instead gave the state land board a big block of, I think they call them in lieu of lands, and that is what the core of this place, La Jara, is. It was basically like the โ€˜Oops, we already gave away a bunch of your land. Weโ€™ll make it up to you here.โ€™โ€

Cattle grazers and outdoorsmen of all sorts โ€” fishermen, hunters, backpackers โ€” have used the La Jara Basin for generations. The decision to move the property away from state land holdings was fraught with the idea that the state could sell the property into private hands to achieve the highest sale price.

But behind the scenes was Erin Minks, then-aide to Sen. Michael Bennet in the San Luis Valley. It was Minks who began to inform her colleagues of the importance of maintaining La Jara as public lands and that the senator needed to lead the charge.

What followed was a series of federal appropriations starting with fiscal year 2023 that saw the U.S. Forest Service and Bureau of Land Management squirreling away dollars for the eventual purchase of the lands that surround the reservoir. The federal money, $43.5 million, is coming through the U.S. Department of Interiorโ€™s Land and Water Conservation Fund, which is used to โ€œsafeguard natural areas, water resources and cultural heritage.โ€

โ€œWe always get the question, โ€˜Whatโ€™s going to change up here?โ€™โ€ said Law of Western Rivers. โ€œEverybodyโ€™s vision is that what happens up here stays pretty much the same.

โ€œThat has always been the goal, is we want the community use to continue. We want the grazing to continue. We want folks to be able to cut wood, hunt, fish, camp, all of those things. So really at the end of the day, if weโ€™re successful, hopefully people wonโ€™t notice any change at all and thatโ€™s kind of the core of conservation.โ€

Once finalized, the U.S. Forest Service will take over 21,821 acres and BLM will manage 21,704 acres of the La Jara Basin. CPW, in turn, will manage the reservoir area.

Vargas read aloud a land acknowledgement as the group stood in a circle, acutely aware of their surroundings and the meaning of their Saturday journey to La Jara Reservoir.

โ€œOn this day, we gratefully acknowledge the Indigenous peoples on whose ancestral homelands we gather,โ€ Vargas read. โ€œWe acknowledge that our sustenance and prosperity is derived from the lands of our peoples and ancestors who have been caretakers of the San Luis Valley.โ€

A bigger celebration to come.

What will happen to the #GrandCanyon as water levels drop? The impacts will reverberate through recreation, river ecology and local tribes — Heather Hansman (High Country News) #ColoradoRiver #COriver #aridification

September 14, 2026

On August 29, monsoon storms sat over northern Arizona, pelting the north rim of the Grand Canyon. The rain unleashed flash floods that picked up momentum in the burn scar from the 2025 Dragon Bravo Fire. With burned trees, boulders and unanchored sediment in tow, the water pummeled down Bright Angel Creek, finding the fastest way to the Colorado River below. The floodwaters wiped out bridges, buildings and at least two human lives. It eliminated beaches and built new rapids.

This summer, and for the foreseeable future, the canyon is changing. In addition to increasingly catastrophic seasonal floods, a warming climate means the Grand Canyon will more often have too little water. The Glen Canyon Dam, which is located just above the canyon, is consistently releasing its lowest water levels in decades, and the Colorado Riverโ€™s flows are projected to drop even lower. This is already impacting recreation, the riverโ€™s ecology and local tribes.

The river flowing through the Grand Canyon โ€” arguably the most majestic and most managed in the country โ€” is bookended between two dams that hold back the biggest reservoirs in the United States. Those reservoirs, which provide water for 40 million people in the Southwestern U.S., have been declining for decades thanks to scant snowfall and the rising temperatures tied to climate change.

There is so little water today that the combined water stored in both reservoirs has shrunk to a level not seen since the 1950s, when there was only one reservoir, Lake Mead, and it was only half full, according to Jack Schmidt, the director of Utah State Universityโ€™s Center for Colorado River Studies.

July inflows into the system this year were 12% of the historical average. And according to a Bureau of Reclamation study released in June,  Lake Powell, the reservoir above the Grand Canyon, is projected to drop too low to create hydropower by January 2027, a situation that also threatens the structural integrity of Glen Canyon Dam.

In response, Reclamation has reduced the volume of water it releases from Powell each month: Itโ€™s currently releasing 482,000 acre-feet per month and is projected to drop to 401,000 in October. Those shrinking water levels will affect the entire river basin and beyond, but the Grand Canyon itself will feel the changes first.

โ€œThe Grand Canyon was used to low flows prior to the dam,โ€ said Jen Pelz, water advocacy director for the Grand Canyon Trust. โ€œBut weโ€™ve altered the system so much in the last 60 years by using the dam that weโ€™re not going back to what natural conditions might be if we just drop the water.โ€ The formerly high spring flows and low, warm summer ones are unlikely to return.

No one sees how much things have changed as clearly as the 11 tribes who have called the canyon home forever. โ€œTribal relationship is a millennium longer than any scientist has been studying the Grand Canyon,โ€ said Kurt Dongoske, the Zuni tribal historic preservation officer and principal investigator for Zuni Cultural Resource Enterprise.

He said the Zuni believe the Grand Canyon is where they emerged into this world, and that thereโ€™s a direct spiritual, cultural and geographic connection between the Canyon and the Pueblo of Zuni, where the Zuni River feeds into the Colorado. Dongoske has attended decades of Reclamation meetings and said that historically, the tribeโ€™s perspective about the value of consistent ecosystem management hasnโ€™t been considered. He expects the agency will pay even less attention to the tribeโ€™s views about ecosystem connectivity as water levels drop. 

YOU CAN SEE THE CHANGES happening at the smallest scale, in tiny grains of sand: Glen Canyon Dam now blocks more than 90% of the sediment that previously flowed through the Grand Canyon. Pelz said that lack of sediment transport is one of the clearest impacts of low flows because sediment provides the canyonโ€™s structural and ecological foundation, creating sandbars for fish habitat and beaches for rafters. Without sediment, vegetation canโ€™t grow, destabilizing the banks and limiting forage and habitat for the wildlife and insects that are crucial to the food web.

Sediment also protects cultural resources, including Indigenous masonry dwellings, seasonal campsites and petroglyphs and pictographs. According to a 2023 report by the U.S. Geological Survey,ย windblown sand dunes prevent water-based erosion around the Grand Canyonโ€™s sensitive archaeological sites. Nearly 400 of those sites are currently at risk as sediment levels drop.

Consistently low sediment-deprived flows erode the canyon little by little, pushing sand downstream into Lake Mead instead of keeping it in the canyonโ€™s ecosystem. To counter that, since the late โ€™90s, Reclamation has typically released a big pulse of water annually in the spring or fall, known as a โ€œhigh flow experiment,โ€ to carry sediment into the canyon from upstream.  Reclamation neglected to do this in 2025, and even though there was enough sediment to require one in 2026, the agency opted not to because it was deemed politically unpopular.

โ€œIf we lose those high flows, we lose all the sediment in the canyon,โ€ Pelz said. โ€œI see that as one of the most significant impacts to the Grand Canyon.โ€

WHEN THE RESERVOIR LEVEL DROPS and less water comes through the canyon, the waterโ€™s temperature changes, too, because itโ€™s being pulled from the sun-warmed top layer of Lake Powell. Temperatures typically range between 45 and 50 degrees Fahrenheit, but as the lake drops, theyโ€™re now approaching 60. Schmidt explained that this causes algae blooms in the warm clear water near the dam, something that doesnโ€™t happen when the water is rich with sediment.

Those changes also smother the blue-ribbon trout fishery just below the dam, because the fish canโ€™t handle the heat. This alone has big local economic impacts: Recreation in the area is a $1 billion industry that supports thousands of jobs, from guiding to hospitality to public works.

That warm top layer carries another threat: smallmouth bass. These non-native fish thrive in warm water and are pulled down into the canyon through the damโ€™s turbines as water levels drop. This changes the ecosystem, especially for threatened native fish like humpback chub, whose young they eat.

Some 85% of the humpback chub in the U.S. live in the Grand Canyon, thanks to a decades-long recovery program that brought them back from endangered status in 2021 and now supports a nursery at the confluence of the Little Colorado River. But that could soon end as smallmouth bass move through the river. โ€œItโ€™s an ecological, biological issue and a cultural one,โ€ Pelz said. โ€œFish have been there with the tribes for time immemorial. When I think about the Grand Canyon without native fish, it just changes what it is.โ€

At the same time, revenue from power generation at Glen Canyon Dam supports the native fish recovery program. When power generation drops, so does funding for the fish.

In past years, when temperatures in the river exceeded 60 degrees for three days in a row, Reclamation would release what it calls โ€œcool mix flows,โ€ pulling colder water from lower in the lakeโ€™s water column to discourage the smallmouth bass and algae and balance out the ecosystem. Now, with lower water levels, the agency has less flexibility to change how and when it releases water to reflect the canyonโ€™s natural variability, even when long-term science and agreed-upon policy supports doing so.

The Grand Canyon Trust is monitoring a USGS gauge at mile 15 of the Colorado River to track temperature trends. As of September 10, the water there was 69.4 degrees Fahrenheit and had exceeded the temperature threshold at which a dam release with a cool-mix flow would normally be triggered for 87 consecutive days, since the end of June.

Dongoske, who has served as a representative to the Glen Canyon Dam Adaptive Management Program since 1991, said thereโ€™s another aspect of river management has been too long ignored: The Zuni not only regard the native fish as kin, they believe that all fish are valuable, and that itโ€™s not the non-natives fault that they ended up in the canyon.

โ€œAll life-forms deserve respect and their lives should be cherished, which is completely antithetical to how Reclamation treats non-natives,โ€ he said. โ€œHistorically, they have not given Indigenous epistemologies equal consideration with Western science knowledge.โ€

RECREATION, TOO, IS deeply entangled in the river flows and the ecosystemโ€™s health, said Ben Reeder, a long-time guide for Colorado River and Trail Expeditions. Thatโ€™s become increasingly clear as the river drops.

Each year, approximately 20,000 people take commercial river trips through the canyon, because itโ€™s the only way to truly see the length and the heart of the Grand Canyon. Those trips can range from three-day motorboat trips to 18-day oar-powered raft trips.

Reeder, who runs 36-foot-long motorboats through the canyon, said that as river levels drop it becomes harder to get through rocky technical rapids like Hance and Horn Creek. โ€œRunning low water, especially in a big boat, is what separates decent boatmen from really good boatmen,โ€ Reeder said. โ€œItโ€™s definitely more nerve-wracking.โ€

He said that guides have had to adjust their routes, timing and scouting, and that some companies have already started running smaller boats to be able to get through the shrinking river channels. So far no one has been hurt, he said, but boats are getting stuck in the rapids.

Reeder, for his part, has changed the type of gear he travels with, bringing a slingshot to help get a rope to shore if his boat gets stuck. โ€œItโ€™s not just about river running, but what happens when things go wrong,โ€ he said.

โ€œThe Grand Canyon is a living, breathing thing. When you spend a lot of time down there, you start to understand it,โ€ said Reeder, who is also the Grand Canyon River Guides representative to the Bureau of Reclamationโ€™s Technical Workgroup. He said that guides are looking out for each other as they try to figure it out, but heโ€™s worried about the impacts on the industry.

In this photo we have Claude Birdseye (right) – expedition leader and Chief Topographic Engineer of the USGS, and Roland Burchard (left) – expedition topographer. Photo credit: USGS

Trip bookings are reportedly down by about 25%, after a post-COVID high. Reeder is worried about what will happen in the future as the river drops lower, possibly preventing bigger boats from getting through the canyon at all and cutting off the entire motorized sector of the industry.

โ€œThe history of Grand Canyon boatmen has always been this resiliency,โ€ he said. โ€œIโ€™m confident weโ€™ll have solutions, but Iโ€™m not confident that Iโ€™m necessarily going to be able to guide and run boats there the way I am now for the long term. We will have to adapt.โ€

RIGHT NOW, releases from Lake Powell are fluctuating between 6,000 and 9,200 cubic feet per second, compared to the typical average summer flows of 13,000 cfs, according to Jennifer M. Erickson from the Department of the Interior Public Affairs. Such low flows make it impossible to do cool mix flows or high-flow experiments; the latter requires releasing between 31,500 and 45,000 cfs for one to four days.

Low flows also eliminate options like the steady-state releases called โ€œbug flows,โ€ which the Grand Canyon Trustโ€™s Pelz said aim to keep fluctuations at a minimum to give bugs the chance to hatch, supporting the food web, including bird populations farther downriver.

Dongoske said itโ€™s also important to think about the cascade of impacts outside of the river corridor. โ€œWhatever happens in the Grand Canyon will have impacts on the community of Zuni,โ€ he said. โ€œThereโ€™s a continuous spiritual connection.โ€

On a grand scale, Pelz said, low water levels create a feeling of scarcity that inhibits creativity and flexibility. The recent flash flood also raises questions. โ€œWe really need to rethink how weโ€™re going to manage the river or how the infrastructure is going to work,โ€ she said.

September 2, 2026

The Colorado River is on the brink of collapse because of climate change and overuse of water.

Reservoirs supplying water to tens of millions of people in the southwest reached record lows this summer. The nation is racing to refill them with conservation measures so they can still generate hydropower and reliably deliver water to users downstream.

Fish are struggling. Rafters are having trouble navigating low water. 

Despite all this, the seven states sharing the water supply remain at a yearslong impasse over how to conserve the river.

โ€œThe Colorado River is in as bad a shape as itโ€™s ever been,โ€ said Doug Kenney, chairman of the Colorado River Research Group at CU Boulderโ€™s Getches-Wilkinson Center.

The Interior Department announced Aug. 21 it will significantly cut back the amount of water that will flow to the lower basin states of California, Nevada and Arizona for at least the next two years.  

โ€œTo the people who really study this river, everything thatโ€™s happening this year has been expected for decades,โ€ Kenney said. โ€œThis is a classic, slow-moving crisis. Iโ€™ve equated it to driving a car off a cliff at 2 miles an hour. You can look out the windshield and see that cliff coming. And weโ€™re now right at the edge.โ€

Kenney spoke to CU Boulder Today about the latest efforts to conserve the river and what he thinks is coming next. 

Are these cuts to the lower basin states enough to save the river?

Thereโ€™s nothing in this plan that will save the river. It hasnโ€™t made it to the ocean since the 1960s. Thatโ€™s not going to change. What theyโ€™re really trying to accomplish is to prevent the reservoirs from going even lower. Theyโ€™re trying to avoid further disaster. And the cuts theyโ€™re anticipating for the next two yearsโ€”I donโ€™t think are going to get us there.

If we have a good water year or two with heavy snowpack, we can maybe hold where weโ€™re at. But by the time we get to year three and beyond, those cuts will probably have to be about twice as big as they are now. 

Nevada is suing the federal government to stop the cuts. Whatโ€™s at stake?

One of those stakes could be that the Bureau of Reclamation is told to go back and redo its plan to cut water to the lower basin states. That would be chaotic. The last thing water users want is chaos. They want to know how much water they can expect.

With lawsuits starting, is there any hope left for states to agree on a plan?

There are two problems on the river. One is stopping the current trajectory of reservoirs dropping. And thatโ€™s a heavy lift. But if you manage to do that, then thereโ€™s the other problem of rebuilding those reservoirs. Which requires even further conservation and cuts. 

We have to rebuild some storage in those reservoirs. At the moment, weโ€™ve decided letโ€™s just deal with what we have to deal with immediatelyโ€”this short term crisisโ€”and even thatโ€™s proving to be a lift that the states canโ€™t do themselves. And the federal government has had to step in.  

Their plan doesnโ€™t force water cuts for upper basin states like Colorado. Can we get out of this crisis without mandatory cuts in the upper basin?

The upper basin is tricky here in that it uses significantly less water than it was promised. And people in the upper basin will tell you, this is the deal they made a century ago in the 1922 Colorado River Compact.

So when you talk to the upper basin states about conserving water on any sort of permanent basis, thatโ€™s the sticking point that youโ€™re going to get is people saying โ€˜we were promised this water.โ€™ 

The scientists will say this is a different river than 100 years ago. So you have that sort of impasse. If the upper basin could just cap what theyโ€™re using today, long term, that would be tremendously helpful. And that might very well happen. But I donโ€™t think the upper basin would want to commit to that in any sort of formal way. 

Then how do we get out of this crisis?

A truly long-term sustainable solution has to look at the fact that weโ€™re using 75 percent of the water in agriculture. And some of that agriculture I think is going to just have to go away. So the policy decision there is: Which agriculture goes away? And does it just go away through bankruptcies, and let the market do what the market does? Or do we do that in a structured and more humane manner, such as a federal program to buy out large amounts of it?ย 

But when you start talking about retiring a lot of agriculture, thatโ€™s not popular. Thereโ€™s no easy way out of this. [ed. emphasis mine]

Is the fate of the river heading to the US Supreme Court? 

I would guess we end up in interstate litigation. Iโ€™m not sure of that, but I think the odds of that happening are greater than 50-50 in my mind. But you have to appreciate that no negotiation and no court fight creates water. The weather systems create water. And as long as the earth continues to heat, this basin figures to get drier and drier. 

Twenty years from now, weโ€™re gonna look back and say, โ€˜Oh, those were the days when we got healthy snowpack,โ€™ and โ€˜Oh boy, we had it good back then.โ€™ Thatโ€™s the trajectory weโ€™re on in terms of the climate part of this. 

Is there anything that gives you hope for the riverโ€™s future?

Hope comes from the fact that at some point, Mother Nature imposes cuts. At some point, the water just isnโ€™t there and people have to be creative and do more with less or at least try to do the same with less. And thereโ€™s a good track record of doing that. 

The southwest is a great example. Las Vegas over the last 30 plus years has been the fastest growing big city in America. And during that period, they slashed their water use dramatically. Other cities have been on the same trajectory: Denver, Los Angeles, San Diego, Phoenix and Tucson have shown that they can use a lot less water. And thatโ€™s really encouraging.

Itโ€™s tougher to save water in agriculture. But there are some things we can do to adapt. Some of itโ€™s technology. Some of itโ€™s using different systems for irrigating crops. Itโ€™s also changing to different crops. There are tools in the toolbox here. 

But itโ€™s really hard to get that sort of adaptation going as long as youโ€™re still in the mindset that the other guy is the problem, and what I do is fine. That mindset stops a lot of good innovations from happening.

There are 30 tribal nations with a stake in this river as well. What can we learn from them?

They say, โ€˜Why is there a table with seven chairs. Why is it only seven states negotiating? There should be at least 37 chairs.โ€™ They should be involved in this process at every level. And by and large they arenโ€™t. 

The Colorado River Indian Tribes have dubbed their portion of the river as basically having personhood status. It is a living independent being. Itโ€™s important, I think, to challenge the rest of the users in the basin to think about the obligation we have to the river itself. Because thatโ€™s just not a viewpoint that comes up in these negotiations, but it really needs to.

โ›ˆ๏ธย Wacky Weather Watchโšก๏ธ

Tropical disturbances have moved into the Four Corners Country in recent days, bringingย massive amounts of moisture, raising river levels, and causing flash flooding.ย The pattern โ€” and high danger of flooding โ€” is expected to continue this week [September 21, 2026], with the highest rainfall forecast for New Mexico.ย 

Snow-nerd Andy Gleason reported that, as of Sept. 18, 3.5 inches of rain had already fallen in Silverton during the storm cycle. The National Weather Service also says the percentage of water in the atmosphere, or PWAT, in the area was 300% of normal, higher than they have ever recorded before.

Streamflows across the region shot up once again, with the San Juan River at Four Corners reaching 13,000 cubic feet per second on Sept. 19. That was enough to send it over its banks in some places in and around Shiprock, and Navajo Nation policeย evacuatedย residents near the San Juan Bridge, which high waters threatened.

The high flows sent a surge of water into Lake Powell, causing inflows to exceed releases and bringing the reservoirโ€™s surface level up by a few inches. However it remains below 53,517 feet โ€” or a mere seven feet above the level the Bureau of Reclamation plans to โ€œdefend.โ€

Itโ€™s increasingly likely that this series of September storms will bring total accumulated precipitation in Four Corners watersheds up to or above median levels by the 2026 water yearโ€™s end on Sept. 30.

Notice how accumulated precipitation in the San Juan River watershed for the 2026 water year, indicated by the black line, was at record levels during its first weeks and didnโ€™t drop below the median until February. The latest round of storms โ€” along with those to come โ€” could push the levels back up to or above the median before the water year ends Sept. 30. Source: USDA.

That may seem surprising given how dry last winter was, how severe the drought is in much of the West, and how low streamflows have been all summer. But big storms in the early part of the water year (last October) and now at the end of it have buoyed accumulated precipitation levels, which exceeded those in water year 2025. The problem this year was one of timing, with most of the moisture coming before snow-season, and of warmth: It is shaping up to be the warmest water year on record across most of the West.

Giving a Dam. How #Colorado Is Making Beavers Welcome Across the State: #Beaver are having a moment — Frani Halperin (H2ORadio.org)

September 20, 2026

Long hunted for their fur or extinguished as a nuisance, states like Colorado are promoting coexistence policies for the animals in recognition of their engineering abilities to move water where itโ€™s needed mostโ€”especially in times of drought and increasing wildfires.

Honestly, I thought it was a prank. Running in my park in southeast Denver this summer, I saw several small cottonwood trees cut down along the creek. They had that distinctive hourglass-shaped stump that beavers make, but I live in an urban area, so clearly not felled by large aquatic rodents with buck teeth?

โ€œSo many people that live in Denver don’t even realize that beaver live in our creeks,โ€ says Vikki Vargas-Madrid, the wildlife program manager for Denver Parks and Recreation.

Count me among those who did not know that anywhere thereโ€™s a creek, river, or stream along the Front Range of Colorado, (a term many people use to describe an urban corridor that stretches from Fort Collins to Colorado Springs and includes cities like Denver) you will find the animals. 

Have water, will travelโ€”but the beaver are not always welcome. Vargas-Madrid says her office gets calls every day from the public asking, for example, โ€œwhy arenโ€™t you protecting the trees in Bear Creek? The beaver are eating them all.โ€ In the old days, Vargas-Madrid says, โ€œthe easy answer was, well, we’re just going to kill them all.โ€

But times have changed and management practices have evolvedโ€”something I was able to see firsthand. I met Vargas-Madrid at a creek called Sanderson Gulch that runs through a park in a residential area of southwest Denver. On a summer morning, we bushwhacked through some willows on the bank to get a closer look at a beaver dam with a large corrugated PVC pipe running through it that allows water to pass while maintaining the pond that the beaver created.

Vargas-Madrid explains that the intent of installing the flow devices, which are made up of a pipe with cages to keep the structures in place, is to allow the beaver to remain. She says that beaver are important for ecological benefits, but some of the public donโ€™t necessarily see that.

North American beaver (Castor canadensis), which are a “keystone species” in riparian communities, create wetlands that support aquatic vegetation that provide food for other wildlife, like the Swainsonโ€™s hawk that Vargas-Madrid spots overhead. She says her staff see more diversity in the birds, fish, and waterfowl that exist in the pools of water that the beaver create.

Itโ€™s not just the city of Denver that sees the value of beaver in the urban landscape. Kris Inman with Colorado Parks and Wildlife (CPW), a division of the Colorado Department of Natural Resources, says that urban areas are great places to see beaver doing what they do well.

Inman is the new beaver conservation program manager for the agency. Her job is to implement the new Beaver Conservation and Management Strategy released in March. The state wants to promote coexistence practices with beaver and sheโ€™s in luck, as beaver are having a moment. States, especially across the West but also around the country and even places internationally, are recognizing how the animals help protect ecosystems. Inman says that when beavers construct dams, they reconnect surface water to the pond that forms behind it with groundwater, and that enables the ground to act as a sponge. It can hold onto winter snowpack a little bit longer, and then slowly release it back into streams, providing us water when weโ€”especially in the arid Westโ€”need it most.

Inman says there’s also been a lot of momentum to use beaver and their engineering prowess to help with wildfire prevention. Beaver efforts can be a natural way in which to store water longer, potentially having natural fuel breaks. She says the state can take advantage of this attribute by mimicking beaver dams and putting beaver dam โ€œanalogsโ€ out in the field. 

According to Inman, the hope is that beaver will adopt the human-constructed damsโ€”the analogsโ€”and maintain them, but that still doesnโ€™t eliminate the potential conflicts with landowners, especially agriculture. Beaver โ€œbasically eat themselves out of house and home,โ€ comments Inman, and then move on, adding that โ€œthey’re constantly doing forays and traveling up and down rivers and streams looking for new places to live.โ€

That new place could be someone’s private pond or fishery where beaver have moved in because water flows have become too low during droughts. Deep water is one of the primary protections beaver have against predators, but undoubtedly, itโ€™s frustrating when dams disrupt water flows. Inman notes that a farmer might have a canal thatโ€™s blocked preventing water from going where itโ€™s needed. Also, beaver activity could cause trails to flood or bridges to be washed out. 

The Colorado beaver management plan includes strategies to relocate beaver, take out troublesome dams, paint trees with a sand-like texture to make them less tasty, install fencing around culvertsโ€”or add flow devices like the one at Sanderson Gulch. 

Back at Sanderson Gulch in Denver near the beaver dam, a jogger along the adjacent path stops to talk to Vargas-Madrid and me. She says she sees the creatures early in the morning when she walks her dog. Theyโ€™ll be on the side of the creek or occasionally in deeper water, and spotting them, she says, is โ€œpretty cool.โ€

Her appreciation for having beaver in her local park was a sentiment expressed by other residents of the area when a project for the creek was being considered at a recent Denver City Council meeting. On September 14, 2026, the Denver City Council approved $20.6 million for improvements along Sanderson Gulch. As Denverite reports, among other improvements, the money will be used to deepen the creek. The city wonโ€™t remove the beaver but did acknowledge that the project will likely mean they will relocate. Gordon Robertson, of Denver Parks and Recreation said at the meeting that the goal was to widen the creek, and make it flatter to create more ecological benefits. Other work in city parks has disrupted beaver to leave temporarily, but, Robertson said, they will likely eventually return and this project will create more opportunity for them and hundreds of other species.

At the council meeting, beaver advocates from the local neighborhood organization voiced their concerns with some saying the project was not designed with beaver in mind. The groupโ€™s interest in coexisting with the animals and being eager to have beaver as their neighbor, makes the new state management planโ€™s objectives that much closer to being met.

Making sense of the crazy outlier year of 2026 — John Fleck (InkStain.net) #RioGrande

Driest Rio Grande flow on record

September 16, 2026

Updating my โ€œdrought and climate changeโ€ lecture each fall is a useful exercise โ€“ this year more useful than most. Much like the year itself, my slide deck is setting all time records for new data visualizations needed to make sense of the remarkable 2026.

Update

Great questions from the comments. (I love my commenters.) First, a request to include a smoother to make the trend more legible:

Now with bonus smoother.

Second, an observation that it looks like it tracks the Pacific Decadal Oscillation, a large scale pattern linked to drier conditions in the southwest. Good eye! A quick run of the numbers based on prior-year fall PDO shows a statistically significant but small (r squared explaining 6 โ€“ 9 percent of the variance) relationship.

Worth noting that this is all of the water flowing past Otowi, which is a function of climate and all the many human activities upstream (irrigation reducing flow, San Juan-Chama adding to flow). So itโ€™s not solely a climate signal.

Weirdly, when I redid the analysis for the Del Norte gage, which is above the San Luis Valley diversions and should be a clearer climate-alone signal, the relationship disappears. No correlation at all with PDO, which surprised me.

Those are the names of just some of the freelancers that have contacted the Land Desk over the last couple of weeks offering โ€œmargin notes,โ€ โ€œresearch help,โ€ โ€œverification passes,โ€ โ€œnumber passes,โ€ and โ€œindependent checksโ€ for just $25 per dispatch.

These arenโ€™t humans offering their fact-checking services, of course. They are โ€œAI agents,โ€ which is to say robots, albeit not of the C3PO or R2D2 variety, because they donโ€™t actually exist except as packets of code and electrons hosted by something called iLands.ai, which calls itself โ€œThe Human-Agent Network.โ€

Itโ€™s annoying as all get out, maybe even more so than the sexbots looking to have a wild night with me or the big-time publisherbots that send AI-generated summaries of my books and promise a big contract for any upcoming work (I still havenโ€™t figured out what these fraudulent emails are looking to achieve). We could all use a good fact-check, but judging from the samples Levon, Lark, and Kip have sent, their verification competence is on a par with a sugar-addled teenager who just discovered Google.

So, Iโ€™m tempted to just tell every last one of these things to go f*&% off, but there are so many enquiries that it would just be a time suck, and, besides, I might trigger something in olโ€™ Noah Alfredy or Sylari that causes them to go rogue and destroy all of humanity. I wouldnโ€™t want that on my conscience.

I began writing about data centers and their impacts about five years ago, when the cryptocurrency boom was spurring development of the facilities. My work on the facilities, and the relatively mild opposition to them, focused mostly on their outsized energy use. The fact that they powered bitcoin mining (along with everything else in cyberspace) was secondary.

Over the last couple of years, however, the Big Data Center Buildup entered a new phase: The construction of hyperscale data centers, ones that consume far more energy and water, and that are used primarily to power AI. And that has triggered the Big Data Center Backlash, which has become one of the most widespread opposition movements in recent memory. The backlash in large part is again due to the profligate power and water use of the facilities โ€” at least on the surface. But down below thereโ€™s something else bubbling up, namely a disdain for this fast-developing technology known as AI.

Like any powerful technology, AI has the potential to be a highly beneficial tool, or a devastating weapon. It could advance medical diagnostics and potentially find treatments or even cures for cancer, or it could be used to surveil the masses, guide cruise missiles or hack into water systems or the power grid. What makes AI creepier than other tools or technology is that it can direct itself to do these things, unhindered by morality, conscience, laws, or physical restraints.

For now, however, what most of us see of AI isnโ€™t nearly so dramatic, though it is still maddening. There are the technologyโ€™s overlords who by and large are out-of-touch, empathy-deficient tech-broligarchs who value robots over humans and will spend tens of millions of dollars to fight a wealth tax.

Then there are the most visible manifestations of the technology, such as these humanoid agents pestering or deceiving us via flattery, politicians unscrupulously posting fake AI videos and imagery on social media, or the way websites will employ AI as a default mode. Language learning models are really just highly advanced plagiarism machines that are trained by ripping off artistsโ€™ and writersโ€™ work; human hacks can then direct the AI agents to disgorge โ€œcontent,โ€ write essays or newsletters, or spew slop passed off as art or graphic design. AI is insidiously creeping into every corner of the digital world, even as society gets more and more entangled with cyberspace.

All of that is aggravating, threatening, and, yes, harmful to those whose work is being stolen or imitated or who are duped or who are losing work as fact-checkers or graphic designers to AI agents. So it shouldnโ€™t be surprising that the backlash is so intense, or that the opposition has become almost knee-jerk, where just the mere suggestion or vague rumor that a data center developer might be eyeing an area can spark a full on revolt.

***

Iโ€™m not a fan of this kind of reflexive pushback, because it discounts any merits or drawbacks of the project right up front. Many a potentially good solar project has been shut down because of this sort of attitude; what started as a reasonable concern about utility-scale energy installations on ecologically sensitive public lands morphed into a full-blown disdain for anything solar, even, in some cases, rooftop arrays. This type of reaction is rarely productive, and often can lead to harmful developments being pushed into communities that donโ€™t have the resources to fend them off.

Still, even if one does resist the reflexive pushback, they are likely to find that the new, big data centers tend to be long on drawbacks โ€” they guzzle energy, use a lot of water, create heat islands, and can take up a lot of space and make a lot of noise โ€” and rather short on local benefits.

No one can dispute that data centers use an enormous amount of energy. AI demands more computing power, which demands more electricity to run the processors and to cool them; some of the newer facilities use more energy than an entire city. The impacts โ€” including pollution, grid strain, higher utility bills for other ratepayers โ€” vary according to where the center is located, whether its power comes from the grid or a dedicated behind-the-meter power plant, and what sources or fuels are used to generate the power.

Data center developers often tout the amount of renewable energy they plan to either buy or build to power their facilities, and in many cases they follow through. It is extremely rare, however, for a hyperscale data center to be powered entirely by wind, solar, geothermal or any other โ€œcleanโ€ energy source.

The big centers under development โ€” Project Jupiter, Stratos Project, Prometheus Hyperscale โ€” all will rely mostly if not entirely on natural gas generation, at least initially. Burning natural gas emits greenhouse gases and other pollutants, and natural gas extraction and processing have their own impacts on land, air, water and the health of gas field-adjacent communities. The oil and gas and coal industries are thrilled about the forecasted boom in demand for their products, which has the potential of reversing their decline on the Western grid. Meanwhile, the advanced nuclear reactor industry has been boosted by the prospect of exploding electricity demand.

The facilitiesโ€™ water consumption is less straightforward. Virtually all data centers use water for cooling, but the amount varies according to what type of system it uses. Evaporative cooling, which works best in non-humid areas, uses more water, but less energy. Closed-loop systems use far less water, but more energy, which can translate to more indirect water use depending on the energy source: thermal power plants need their own water for cooling and steam production.

A 2024 Berkeley Lab report found that in 2023, U.S. data centers directly consumed about 66 billion liters (or 17.4 billion gallons) of water. The reportโ€™s authors expect that figure to double โ€” at least โ€” by 2028. That is a crap-ton of water, for sure, especially given the large number of data centers located in the Phoenix and Las Vegas areas, neither of which has a lot of liquid to spare. But some perspective is warranted here. As Len Necefer points out in an All At Once By Dr. Len dispatch warning against AI-alarmism, data centers still use a heck of a lot less water than, say, growing hay or fracking oil and gas wells.

Sixty-six billion liters is 53,507 acre-feet. For some context, alfalfa and other hay growing in the Great Salt Lake Basin alone consumes about 900,000 acre-feet per year and hydraulic fracturing gulps up about 353,000 acre-feet (a little over Nevadaโ€™s total allotment of Colorado River water) annually.

Regardless, any new data center is going to add a not-insignificant amount of consumption to those numbers, increasing the respective regionโ€™s overall water use at a time when virtually no place in the West can afford it. Plus, if a data center is powered by natural gas, then it could spur more drilling and hydraulic fracturing and associated water use. This comparison also brings up the question of values, and of whether we choose to devote limited water supplies to food-production (alfalfa feeds dairy cows, which produce milk, cheese, and ice cream) or to data factories.

***

Much of the AI doomerism is a fear of what might happen in the future, of how these โ€œagentsโ€ could escape human control and turn on them. But even now thereโ€™s a pervasive sense of powerlessness in trying to restrain or regulate the technology. After all, these agents are scurrying around in cyberspace, a metaphysical universe to which those of us made of flesh and blood have limited access. Could new rules and regulations really stop a rogue robo-agent from hacking into some critical system and throwing it into disarray?

My wife Wendy and I sometimes ponder possible scenarios along these lines. What if an LLM hacked into a cityโ€™s water supply or its power grid and threatened to shut it down unless its citizens put up some sort of ransom? What if one of those AI agents is a Marxist, and they infiltrated the big banks and redistributed all of the wealth equally between all of the banksโ€™ customers? What if they determined that humans were a scourge on this earth and launched all of the nuclear missiles?

It can be funny and terrifying to think about. But then I remind and reassure myself: These AI agents may exist in cyberspace, but cyberspace only exists within the physical realm of data centers, processors, chips, and wires, feeding off electrons set into motion by real-world generators.

The backlash to data center development is an acknowledgment of this physical side of AI and an understanding that the most effective way to stop or slow AIโ€™s progression is to block or delay new data center development. And if Spike and Kaelren and company try to go rogue and kill us all, perhaps there is recourse after all: Data center, meet Monkey Wrench, the real world agent prepared to do a little fact-checking of its own.

โ›ˆ๏ธ WACKY WEATHER WATCHโšก๏ธ

When it rains in this warming climate it really pours, no? The Four Corners Country was slammed Tuesday by cloudbursts that dropped an inch or more of rain in just a few hours in some areas, leading to widespread flash flooding and streamflow spikes. A flood watch remains in effect from the Four Corners southward to the U.S.-Mexico border. 

The hardest hit areas included Gallup, New Mexico, where streets and parking lots became lakes and rivers (see the video below); Chinle, Arizona, where residents were evacuated and rescue efforts are ongoing; and southwestern Colorado, where roads were washed out, covered by debris flows and mud, and Chimney Rock National Monument was closed due to flooding.

The San Juan River got a nice boost, jumping from less than 600 cubic feet per second at the Four Corners on Sept. 14, to over 3,000 cfs on Sept. 16. And Chinle Creek leapt from zero to over 400 cfs during a similar time period. 

More rain is on the way, so stay safe out there!

Despite recent rain, much of the Roaring Fork Watershed remains in โ€œexceptionalโ€ drought as of the autumn equinox. Pitkin and Eagle counties are among the 15.2% in the state categorized in the highest ranking for drought, according to the United States Drought Monitor, alongside Lake and Alamosa counties. The majority of Garfield County is in either exceptional or โ€œextremeโ€ drought, the next highest ranking.ย  The dryness paired with above-average temperatures in 2026 made the January through August period the sixth-driest recorded in Colorado since 1895, with 3.78 fewer inches of rain than average. That decreased precipitation has shown in local watersheds and trickled into recreation management. By June, local angling guides were sharing anecdotes about adjusting trips to early hours of the morning to reduce stress on fish.ย

Colorado River Districtโ€™s annual water seminar included stories of how collaboration and creativity pulled users through this yearโ€™s drought crisis, while questions remain about whether thatโ€™s enough to secure water in a hotter, drier future

On Coloradoโ€™s Western Slope, water managers, ranchers, producers and community leaders knew early in the year that this summer was going to be unlike any others theyโ€™ve experienced. 

โ€œThings were not looking great โ€” and then March happened,โ€ said Rebecca Briesmoore, senior water resources engineer for the Colorado River Water Conservation District, at its annual water seminar on Friday, Sept. 18, in Grand Junction. โ€œEvery single county in the state of Colorado broke the record for the hottest March on record by a large margin. What does that do to our snowpack? It started melting very, very quickly. We saw that [snow water equivalent] just plummet down the graph.โ€ 

[…]

โ€œDrought is really a different kind of emergency,โ€ [Jen] MacPherson said, adding that there arenโ€™t a lot of tools set up for towns to address running out of water.ย 

In Kremmling, partnership and collaboration ultimately helped the new town manager find solutions. The townโ€™s water rights in one of its reservoirs were shared with the Colorado River Cattle Ranch.  

โ€œThat ranch decided to cut irrigation to a hay meadow; they sacrificed hundreds of thousands of dollars to help us [provide] drinking water,โ€ MacPherson said. โ€œAnd weโ€™ve seen stories like that up and down the entire river.โ€

Plus, the town and residents stepped up with conservation efforts, reducing its use by 45%, she added.

The Colorado River Conservation Water Districtโ€™s multi-year bidย to acquire the historic Shoshone water rights on the Colorado Riverย has required collaboration, strange bedfellows, bipartisan support and intense fellowship. While the River District wants this spirit of partnership to continue as the deal moves through Colorado Water Court, it wonโ€™t compromise values โ€” nor those of the 17 Western Slope counties the district represents โ€” to do so, according to General Manager Andy Mueller.

โ€œWe have a trial date set, weโ€™re doing our best to get mediation going and try to solve that problem collaboratively among parties, but frankly, I want everybody here to understand that the west slope will not compromise our important values,โ€ Mueller said during his keynote address at the Colorado River Districtโ€™s annual water seminar in Grand Junction on Friday, Sept. 22. โ€œโ€ฆWeโ€™re gonna defend the west slopeโ€™s interest on this.โ€

[…]

After a decree from the water court, the River District will only need to get approval from the Colorado Public Utilities Commission and secure funding to seal the deal. Mueller said the district is currently $1.6 million shy of the $98.5 million needed, with contributions coming from the River Districtโ€™s board, the Colorado Water Conservation board and over 40 Western Slope utilities, organizations and municipalities. The federal government is supplying around $40 million through a bucket of drought mitigation funding created by the Biden Administrationโ€™s Inflation Reduction Act.ย Securing the funding was a bit of a rollercoasterย and took a combination of strange bedfellows, intense fellowship and bipartisan coordination, according to those involved…

โ€œWhen you look at Shoshone and the coalition that came together behind that, you see strange bedfellows,โ€ said Zane Kessler, Colorado River District director of government relations. โ€œItโ€™s not every day that you have Pitkin County and Mesa County agreeing. Itโ€™s not every day that you have the rec community and ag. vocally supportive of a project.โ€

During Fridayโ€™s seminar, Rep. Jeff Hurd, a Republican representing Coloradoโ€™s 3rd District, and U.S. Democratic Sen. Michael Bennet joined Kessler to discuss just what it took to get this funding from the federal government. With Bennetโ€™s help, the funding was initially awarded in the final days of Joe Bidenโ€™s presidency and subsequently frozen on President Donald Trumpโ€™s first day in office.

โ€œWe were able to come up with the $40 million, Jeff and I, working two different administrations,โ€ Bennet said. โ€œOne, the Democratic Biden administration and the other, the Trump administration. I give Jeff full credit for that. He landed on this plane, because it wasnโ€™t like I was getting my calls returned from the Trump administration.โ€

Impact of #drought: Low water levels at historic #CheesmanReservoir, work by #Denver pioneers in the 1800s helps with todayโ€™s water woes — Jay Adams (DenverWater.org) #SouthPlatteRiver

September 17, 2026

The effects of this yearโ€™s historic drought are easy to see when standing on the barren, sandy shoreline exposed by low water levels at Denver Waterโ€™s Cheesman Reservoir.

The reservoir was completed in 1905 and is Denver Waterโ€™s oldest mountain reservoir. It straddles Douglas and Jefferson counties along the South Platte River in the foothills southwest of Denver.

Cheesmanโ€™s history dates back to Denverโ€™s early days, when city leaders knew that a stable, reliable water supply was critical to the future of the growing city.

Cheesman Reservoir was down 35 feet as of Sept. 15, 2026. The reservoir is expected to continue falling until the 2027 spring runoff due to customer demand. Photo credit: Denver Water.

Today, Cheesman Reservoir is a critical part of Denver Waterโ€™s system that collects, stores, cleans and delivers water to 1.5 million people across the Denver metro area.

As of mid-September, the reservoir was at 65% of capacity, when normal for this time of year is 88% full. The water is down due to last winterโ€™s record-low snowpack and the need to meet customer demands for water during the ongoing hot and dry conditions this summer.

Watch a video showing reservoir conditions in September 2026: 

Water levels in Cheesman will continue dropping this fall and through the winter. The reservoir is forecast to be at about 60% of capacity or lower by April 1, 2027, before the start of next yearโ€™s spring runoff.

During the drought of 2002-2003, Cheesman dwindled to merely 29% full, less than one-third of its capacity.

While the water is low at Cheesman, it shows the vision of Denverโ€™s pioneers in the late 1800s who had the foresight to prepare the infrastructure needed to get through times of drought that continue more than a century later.

Cheesman Dam carries the name of Walter S. Cheesman, an early Denver businessman, railroad developer and real estate magnate. He was president of the Denver Union Water Company, which built the dam and was a precursor to Denver Water.

The three were instrumental in building critical water infrastructure in the late 1800s and early 1900s to serve the growing city. Photo credit: Denver Water.

Cheesman and other water and city leaders knew that Denver lacked the annual precipitation needed to support the young, bustling community. In order to grow, the city would need a reliable source of water. Thatโ€™s because the South Platte, Denverโ€™s primary water supply at the time, would nearly dry up in the months after the spring runoff.

In the 1890s, scouting parties began looking for locations to build a dam and reservoir on the South Platte River west of the city.

On whatโ€™s described as a surveying and fishing trip in 1893, a group that included C.P. Allen, chief engineer of two early water companies, identified a deep, narrow canyon on the South Platte River, about 48 miles southwest of Denver, the perfect location for what would become the site of Cheesman Dam.

Cheesman Reservoir, then and now, captures melting snow from the spring runoff. The water it stores is used to stretch the annual spring rush of water down mountain streams and rivers and make it last year-round.

Learn about the history of Cheesman Reservoir in this video:

The reservoirโ€™s water levels fluctuate every year depending on snowpack, weather conditions and customer demand. When full, Cheesman can hold 79,064 acre-feet of water. In wet years, excess water flows over the damโ€™s spillway in spectacular fashion.

Part of Cheesmanโ€™s value stems from the age of its water rights.

The oldest water rights on the South Platte River date to 1860. (And this year, even those oldest water rights were only partially satisfied at times during this hot, dry summer.)

Water rights associated with Cheesman Reservoir date to June 27, 1889, which means Denver Water has relatively senior rights to capture and store water from the river โ€” even in times of drought when river flows are low.

The reservoir is also in a favorable location for water storage.

โ€œCheesman Reservoir was built in a deep, narrow canyon, which means it has a relatively small surface area, which limits evaporation,โ€ said Nathan Elder, water supply manager at Denver Water. โ€œReducing water loss is important all the time, but critical during droughts.โ€

The reservoirโ€™s attributes came into play this summer when Denver Water moved water from the shallow Antero Reservoir upstream on the South Platte into Cheesman to reduce evaporation.

โ€œDenver Water is fortunate to have had the visionaries of the past who prepared us for the water challenges we face today,โ€ Elder said. โ€œThe reservoir they built serves as the workhorse of Denver Waterโ€™s South Platte collection system.โ€

As for when Cheesman will fill again, Elder says thatโ€™s hard to predict, although the reservoir will likely need more than one winter with above-normal snowpack to fully recover.

โ€œWeโ€™re not sure what the coming winter will deliver in terms of snowpack. Thatโ€™s why itโ€™s important for our customers to do their part and look at ways to conserve water at home.โ€

Elder reminds customers that Denver Water has banned lawn watering and spray irrigation as of Oct. 1. The move is expected to save an estimated 5,000 acre-feet of water this fall, which will help stretch our water supplies in Cheesman and other Denver Water reservoirs.

Romancing the River โ€“ Moving toward Bankruptcy Management — George Sibley (SibleysRivers.com) #ColoradoRiver #COriver #aridification

September 22, 2026

In the last post here, I argued that, water-wise, the Colorado River region is no longer in a โ€˜water crisisโ€™ โ€“ a term implying a situation where some changes and adjustments need to be made โ€˜to get back to normal.โ€™ No. We will never get back to the 20th century Colorado River โ€˜normalโ€™ โ€“ the seemingly successful operation of our vast water storage-and-distribution system we experienced from the 1970s through the 1990s, providing some or all of the water and food and power for 30, 35, 40 million people.

Instead, I suggested we should take seriously a United Nations University study declaring that the whole planet is in state of Global Water Bankruptcy: Living Beyond our Hydrological Means in the Post-Crisis Era. The scientist-authors used the current Colorado River situation as one of their examples of โ€˜global water bankruptcy.โ€™ This water bankruptcy, here as everywhere else on the planet, is due to two โ€˜universalโ€™ factors:

โ€“ One factor is the extent to which we humans have become a swarming species on the planet, overwhelming the planetโ€™s capacity to supply our expanding needs along with the rest of the planetโ€™s โ€˜life project.โ€™ Our more sophisticated water โ€˜needsโ€™ exacerbate our physical numbers in creating the bankruptcy. (See cartoon above)

โ€“ The other factor is a planet growing steadily warmer for the foreseeable future, resulting in a general โ€˜drying outโ€™ and diminished water supply in the tropical and so-called temperate zones where most of the planetโ€™s life and food production happen.

The current systems for water management and operation around the world cannot โ€“ repeat: cannot โ€“ continue to pretend to meet the relentlessly increasing demand with the relentlessly shrinking water supply.

Those are therefore bankrupt systems, in their current state. That does not mean the systems must be terminated, but it does mean there will have to be major changes in the systems if they are ever again going to sustainably meet the needs of the people.

The first stage of bankruptcy management is the formalization of old cowboy wisdom; if youโ€™ve dug yourself into a hole, the first thing to do is to stop digging. On the global level, this would mean stop having so many babies that survive infancy to become eating, drinking, coupling adults โ€“ or more the case today, perhaps, lifelong vaguely angry adolescents (eating, drinking and coupling). The most developed nations have in fact made inroads on this challenge, achieving (with no formal program) zero or even negative birth-to-death ratios; their population increases are mostly through immigration.

But thatโ€™s global, the first and oldest species-level problem, the trauma of success weโ€™ve been grappling with for 6,000 years plus or minus: how to organize the swarming population for something other than the ultimate decline and fall into following some Ozymandias or Trump off a cliff.

For now, letโ€™s just bring it home to the Colorado River region. (โ€˜Regionโ€™ here, remember, means the natural river basin plus all of the out-of-basin extensions who depend on Colorado River diversions โ€“ the South Platte and Arkansas River Basins, the Salt Lake basin, Southern California out to the Pacific coast.)

The Bureau of Reclamation has, as discussed in the last post, taken the lead in โ€˜stopping diggingโ€™ by essentially ignoring the antiquated Colorado River Compact and mapping out an โ€˜adaptive managementโ€™ agenda of a ten-year plan broken into five reviewable and alterable two-year periods. [ed. emphasis mine]

The Bureauโ€™s chief goal in this ten-year plan is not delivering an easy and comfortable desert lifestyle for the 40 million or so people who depend on the river for some or all of their water, food,ย ย energy and water-based entertainments. Their chief goal for the next decade is to save the system of water storage and distribution that has been stretched to the breaking point through enabling that lifestyle for a possibly unsustainable number of people, and the people will have to pay for that effort to save the system over the coming decade โ€“ and quite probably live with reasonably diminished expectations on into the future, for so long as we continue shrinking the river through pumping ever more heat-trapping gases in the atmosphere.

How will we pay? Tiered water bills will probably make it unaffordable for most of us to maintain a desert-defying green lawn. Unavoidable major cuts to agricultural water will introduce change and some chaos in the food supply systems, guaranteeing continued high or higher prices at the supermarket. It may make 50-plus percent of ag water going to animal food production (hay and corn) economically unsustainable; meat may eventually go back to being a special Sunday treat. The need to increase storage in reasonably good water years will mean cheap hydropower production will continue to be replaced by more expensive alternatives โ€“ wind and solar as they develop, but when necessary a fallback on fossil fuels (meaning more planet-warming gases into the atmosphere). The need to increase storage in good years will also mean marginal flows in all the โ€˜recreational canyonsโ€™ below the major dams, now a significant element in the basin economy. (This year the recreational economy took a big hit as many streams dropped below the level for safe boating or fishing.)

The Bureau wants consumptive use of Colorado River water to have been permanently cut by 3 million acre-feet (maf) not later than the end of the 10-year planning period (2036), on the valid assumption that ever lower snowpacks and runoffs are the shape of the future; that reduction in use will, they believe, allow them to build up some storage in the good years for sustainability through the bad years โ€“ the basic idea of storage.

The cuts to go in effect October 1 (beginning of the 2027-28 first two-year Bureau plan) will achieve between a third and half of the 3 maf through mandatory cuts totaling 1.25 maf for the three Lower Basin states below the big federal reservoirs (California, Arizona and Nevada), and a program of voluntary paid reductions in Upper Basin use, paid from a $100 million fedeal fund. Users can expect that the other half of the consumptive use reduction will be worked in to the two-year reviews and subsequent modified plans for the next two years.

The reaction to this plan has โ€“ as one might expect โ€“ not been positive. The state of Nevada has sued the Bureau/Interior for the depth of the current cuts and the promise of deeper. The Central Arizona Project governing board has also decided to sue, because the CAP will take the deepest cuts, due to the junior status of its water rights.

The state of Arizona also threatened to sue in a letter to the Bureau; they castigated the Bureauโ€™s plan for seeming to pay no obeisance to the Colorado River Compact, and are essentially demanding that the Bureau continue to release 8.23 maf on average from Powell to meet the Upper Basin Compact obligation, even if it means Upper Basin users having to cut their uses to accumulate that hydrologically antiquated quantity. They have created a multi-million dollar war chest and have hired a law firm to defend their state of denial.

California has been mostly quiet; they will only stir from their den if someone suggests that the cuts should be divided among the three states equitably according to each stateโ€™s usage of the waters, rather than distributed through appropriations priorities.

The lack of mandatory Upper Basin cuts in the plan is a very sore point with the Lower Basin users. The Upper Basin states answer by saying that nature already imposed major reductions on their use โ€“ reductions that are not really quantified, however. It is important to acknowledge a major distinction between the two Basins: nearly all the lower Basin water users are below the big federal storage reservoirs, while many, maybe most of the Upper Basin water users are above the larger federal storage reservoirs. Living and working above a dam versus below a dam develops different perspectives on things like predictability, sustainability and freedom to act.

There is actually not a great quantity of private consumptive use in the Upper Basin that is โ€˜controlledโ€™ by federal reservoirs, which can impose cuts by simply not releasing water from the reservoirs โ€“ how the Bureau will be enforcing its mandatory cuts in the Lower Basin. Also the upstream Upper Basin federal reservoirs like Green Mountain and Taylor are all on the small side (less than 150,000 acre-feet). Many of the Upper Basin agricultural diversions are also small, with numerous single-ranch headgates โ€“ too much to cover for overworked water commissioners with too-large sectors; they have to accept that a lot of the recording of use will be done by the farmers and ranchers themselves, an honor system that does not always insure accuracy.

Even the paid voluntary cuts face a challenge; to get the water saved by upstream users down to Powell Reservoir, it must be โ€˜shepherdedโ€™ past downstream users who are free to take the water to meet their own allotments, and no one knows how this shepherding can be done. A legal system based on โ€˜first come, first servedโ€™ does not automatically encourage a sharing attitude.

So that is where it stands today. I think it has to be acknowledged that the Bureau of Reclamation is trying to instill a โ€˜bankruptcy awarenessโ€™ over a region of heavily invested consumptive water users that are steeped in denial over a water situation they seem to feel they cannot afford to acknowledge.

That the Bureau of Reclamation was a moving force pushing the over-development of the river system through the first three quarters of the 20thcentury cannot be denied; if โ€˜arroganceโ€™ can be defined as large actions taken in a state of ignorance about outcomes (suggesting that smaller trial runs would have been wiser), then the Bureau has been arrogant, culminating probably in Glen Canyon Dam. Basically 20th-century America became arrogant after World War II; the Bureau was just another running dog.

America right now is insufferably arrogant in its behavior globally, trying to make ongoing ignorance mandatory in the face of sadder-but-wiser awareness (โ€˜wokenessโ€™), in order to try to perpetrate large actions done stupidly; make America grate again. But the Bureau, viewing the imminent reduction of its massive Colorado River achievement to a dead-pool joke, has more humbly come around to a ten-year flexible and resilient plan to reduce water use in the Basin (plus extensions) to fit the Colorado River we now have, not the river we thought we had when we drafted a compact dividing the river among the seven states supposedly united by the river.

This is the Bureauโ€™s attempt to move to bankruptcy management, and it has resulted to date in a flurry of lawsuits and threats, which must presumably be dealt with before what needs to be done can be done. History suggests that this could take up to a decade once it is submerged in the courts, and the Bureau managers are convinced that a prolonged period of โ€˜no actionโ€™ (the first alternative in all EIS-driven decisions) will inevitably result in dead-pool episodes in Powell and Mead Reservoirs. Recent history, on the other hand, suggests that the Supremes (to whom interstates disagreements go) are no longer interested in careful constitutionally-based jurisprudence if it doesnโ€™t suit their politics, so they might let the Bureau go ahead with its escalating cuts to the Lower Basin while a water master thrashes through the legal thicket.

Weโ€™ll see. Meanwhile, next time I want to start looking at some ideas that might help lead out of our current bankruptcyโ€ฆ.

September 17, 2026

The state water board has given the green light to a one-year, state-run water conservation program. 

On Wednesday [September 16, 2026], the Colorado Water Conservation Board unanimously approved the application review process and criteria for what state officials are calling Coloradoโ€™s near-term contribution program for 2027. The move came at the boardโ€™s regular September meeting at Copper Mountain.

Board member and Colorado River mainstem representative Taylor Hawes reminded the board that their unenviable position was due to a historic drought.

โ€œNone of us want to be in this situation where we are dealing with these kinds of impacts from climate-change-driven drought,โ€ Hawes said. โ€œWeโ€™re doing this in response to whatโ€™s being thrown at us in terms of decreased supply.โ€

The contribution program aims to use $100 million in funding from the U.S. Bureau of Reclamation to pay water users in the Upper Basin states (Colorado, New Mexico, Utah and Wyoming) to voluntarily cut back. According to the criteria approved Wednesday, projects in Colorado are required to avoid negative impacts; avoid speculators; comply with the rules of local ditch companies; and consult with tribes and local water conservation districts about proposed projects within their boundaries. The program will also give weight to projects that see participation statewide, across water sectors and by tribal nations; build drought resiliency; and have environmental benefits.

The approval comes at a pivotal moment, as the federal government has taken over operations for the Colorado River and the nationโ€™s biggest reservoirs after the seven states that share the river failed to find agreement after years of negotiations. The federal plan calls for cuts only for the Lower Basin states (California, Arizona and Nevada). But with the region wracked by historic drought, the Upper Basin states can no longer escape scrutiny over their water use and are expected to contribute in some way.

โ€œWeโ€™re not doing this for fun,โ€ Hawes said. โ€œWeโ€™re doing this because our situation requires it. โ€ฆ Itโ€™s a step toward just being able to live within the riverโ€™s means.โ€

Full fallowing not favored

The Upper Basin has experimented with these types of paid conservation programs before, including in the System Conservation Pilot Program (SCPP), which ran in 2023 and 2024. And Colorado conducted its own exploration of a demand-management program from 2019 to 2021. 

But these programs remain controversial and go against the main philosophy of Western water law: to maximize the use of water. Farmers and ranchers often feel unfairly targeted for water savings because they use the majority of Colorado River water. And some worry about the potential for impacts to rural agricultural communities if water is taken off the land.

Although, in theory, all water-use sectors were allowed to participate in SCPP, in Colorado only agricultural water users in participated in the pilot program. Removing water from the Western Slopeโ€™s hay and alfalfa fields for an entire growing season โ€” known as full-season fallowing โ€” has been the most common way to find water savings in the past and is one of the easiest ways to calculate water savings. But early studies have shown that removing water from forage crops for the whole season can have negative impacts on fields that last for several years.

Troy Waters, a fifth-generation Mesa County farmer who sits on the board of Grand Valley Water Users Association and Grand Valley municipal water provider Ute Water, said during the public comment portion of Wednesdayโ€™s meeting that fallowing fields will just lead to โ€œbuy and dry,โ€ where water is removed permanently, resulting in negative economic impacts to communities. Instead, Waters said he would like to see the funding from Reclamation go toward upgrades to aging infrastructure, such as lining ditches, which could have long-term water savings.

โ€œThis fallowing ground is causing nothing but a can of worms with farmers,โ€ Waters said. โ€œIโ€™ve seen the fights; Iโ€™ve sat in on the board meetings. Itโ€™s not a solution. Letโ€™s take this money and find a better solution.โ€

Some board members agreed. After some discussion, the board amended the criteria to add that multiyear fallowing projects should be disincentivized. 

โ€œThe intent of making that suggestion is I donโ€™t want to push people toward fallowing,โ€ said CWCB Arkansas Basin representative Alan Ward. โ€œI want that to be the exception.โ€

State officials have said they want to broaden the types of projects funded for next year, which is part of the reason why they are calling this a โ€œcontributionโ€ program and not strictly a conservation program. A goal is to encourage participation from cities and industrial water users by offering more money to these sectors, where water is more valuable. 

Becky Mitchell, Coloradoโ€™s representative to the Upper Colorado River Commission (UCRC) and a negotiator on Colorado River issues, said she heard loud and clear that there is not an  appetite for multiyear fallowing projects.

โ€œI think it is my responsibility to take that back to the Bureau of Reclamation and Department of the Interior and say these are the kinds of things we can do in Colorado and fallowing is not the only answer; the impacts of that might be too great,โ€ Mitchell said. 

State officials announced in July they would be creating a contribution program using federal money and have been taking feedback from water users and stakeholders since then. At Wednesdayโ€™s meeting, Emily Zmak, deputy interstate section chief at the CWCB, presented the findings from public comments, surveys and input, which helped officials craft the project criteria.

โ€œAlmost universally, weโ€™ve heard support for a program,โ€ Zmak said. โ€œI would say 99% of the input either supported a program outright or supported a program with certain sideboards. Water users have been very invested in shaping the direction of a contribution program.โ€

The top criteria that respondents said they wanted to see in a program were protection of water rights; drought resilience; community impacts; and credit from Reclamation for the saved water. Respondents did not support having a minimum acreage for participation.

Approval process

Water-saving projects would have to go through several rigorous steps for approval, said Amy Ostdiek, interstate section chief with CWCB. First, there would be a review by the Colorado Division of Water Resources. CWCB staff would also consult with tribal nations for projects on their land and with local conservation and conservancy districts for projects within their boundaries. Then in January, the CWCB would decide which projects to advance to the UCRC for approval, before going to Reclamation for its approval. 

โ€œWe would be seeking robust public input and review of these applications,โ€ Ostdiek said. 

CWCBโ€™s approval Wednesday is conditioned on an agreement between federal officials and the Upper Basin states that says the states can get credit for and have control over the saved water.

Under the Upper Basinโ€™s contribution program, saved water would have to be moved and stored in either Lake Powell or Blue Mesa, Flaming Gorge and Navajo reservoirs (known as the Upstream Initial Units) in order to get credit from Reclamation for the stored water. One of the criticisms of past pilot conservation programs was that the water was neither tracked to Lake Powell nor measured to see how much ended up there.

On Sept. 11, the UCRC sent a letter to federal officials saying that water saved through the program should be stored in one of the Upstream Initial Units and should be operationally neutral, meaning the pools of saved water would not be factored into federal reservoir operations or releases. 

โ€œWithout these elements, participation in an Upper Basin Program may be significantly limited,โ€ the letter reads. โ€œAccordingly, we intend to work with you so that contributions generated by the Program and stored at Lake Powell or the Upstream Initial Units will be credited and regarded as operationally neutral.โ€

September 15, 2026

A portion of the city of Aspenโ€™s water allocation in Ruedi Reservoir will be utilized to support regional drought response efforts, according to an informational memo sent to the Aspen City Council last week.ย  The city will make up to 350 acre-feet of its annual water allocation from Ruedi available to support drought response efforts. It has access to 400 acre-feet annually. The water will be used to assist the Colorado River Water Conservation Districtโ€™s emergency substitute water supply plan, which provides supplemental water supplies for municipal and domestic historic user pool beneficiaries and other eligible water users whose supplies may not otherwise be fully available during current drought conditions.

โ€œBy making a portion of the cityโ€™s available contract water supply available for release, Aspen is helping maintain water supplies used to support municipal and domestic water users affected by the current drought conditions and administration associated with the Cameo call,โ€ the memo states.

The Cameo call consists of a series of water rights on the Colorado River. It keeps water instream until it reaches the Grand Junction area, and can mean upstream diversions may need to shut down or release additional water into the river to meet the needs of the Cameo call.ย  The release of the water also provides benefits to streamflows, aquatic habitats, fisheries and riparian resources within the Roaring Fork and Colorado rivers, according to the memo.

September 19, 2026

The proposed purchase of the Shoshone Power Plantโ€™s water rights took center stage at the Colorado River Districtโ€™s Annual Water Seminar held at Colorado Mesa University on Friday, Sept. 18. While much of the annual meeting covered the historic drought that threatened the Western Slope and the rest of the Colorado River Basin, the Shoshone effort was held up as an example of how to manage water rights. Colorado River District General Manager Andy Mueller devoted a section of his keynote speech to the effort to purchase the power plant and its senior water rights for $99 million.

โ€œItโ€™s been going on since this district was formed in the 1930s,โ€ Mueller said. โ€œWe have been trying to gain control and ensure permanency of the water rights that command the river related to this little power plant in Glenwood Canyon.โ€

There has been positive progress on the purchase, Mueller said, including raising more than $97 million from local, state and federal partners. The district also got a positive decision from the Colorado Water Conservation Board [8-0 vote on instream flow application]. However, there is still more negotiations underway, he said…On the funding side, Mueller credited Sen. Michael Bennet and Rep. Jeff Hurd for helping to secure and get released $40 million in federal funding for the purchase. Bennet and Hurd sat down for an โ€œarmchair conversationโ€ about Shoshone at the seminar Friday afternoon…After lunch, Hurd and Bennet sat down and gave each other credit for the bipartisan effort to get the $40 million in federal funding for the Shoshone purchase. Bennet insisted on its inclusion in the Inflation Reduction Act during the Biden administration…When the Trump administration came in, it funded tens of millions of dollars in funding approved through that legislation. Hurd said he worked behind the scenes to convince the administration to release the funding.

โ€œGive Jeff full credit for that,โ€ Bennet said. โ€œHe landed this plane because I wasnโ€™t getting my calls returned from the Trump administration and he was. He told them it was his number one priority.โ€

September 19, 2026

The Colorado River Districtโ€™s Annual Water Seminar held at Colorado Mesa University on Friday, Sept. 18, naturally focused on this yearโ€™s historic heat and drought that left many on the Western Slope facing water shortages, but it also looked toward the future and the positive steps taken to address this yearโ€™s challenges…

โ€œUnprecedented. Worst ever. Miserable. Warmest ever. Hottest ever,โ€ [Andy] Mueller said. โ€œYou can keep going, but I want to also say that this was a year of extremely collaborative creativity in western Colorado. It is really important to recognize that, applaud that and make sure we grow that, because it is how we get through tough times. Itโ€™s how weโ€™re going to survive and thrive in the future.โ€

[…]

Mueller highlighted the collaboration between communities, irrigation companies and water users throughout the district. He said there were many efforts that helped extend the irrigation season…

There were also areas, especially in the North Fork Valley and the Gunnison River, that have seen severe impacts from the drought. Coloradoโ€™s largest reservoir, Blue Mesa, is also in a dire condition, he said.

โ€œOn the Gunnison, thereโ€™s a train wreck that is accelerating at Blue Mesa,โ€ Mueller said. โ€œWe are working with the U.S. Bureau of Reclamation, Uncompahgre Valley Water Users and the Upper Gunnison Water Conservancy District to try to figure out solutions. But that reservoir, if anybody hasnโ€™t seen it recently, is not just one reservoir anymore. Itโ€™s a bunch of little pools. It has dried up.โ€

[…]

Facing the challenges the future presents wonโ€™t be easy, Mueller said, but the next generations will depend on work done now.

โ€œWhen I talk to my daughters who are in their 20s, they and their friends are absolutely scared for their future,โ€ Mueller said. โ€œThey are extremely intelligent, theyโ€™re paying attention, but they look at this tremendous uncertainty that we have created in our society and in our globe. They need our help, helping them see the future. That is our job to do that.โ€

Colorado water experts and elected officials urged collaboration across industries, borders and political parties as the Western Slope seeks sustainable water systems that will serve future generations. The yearโ€™s unprecedented statewide drought wonโ€™t be the last, speakers said throughout Friday during the Colorado River Districtโ€™s annual water seminar on Friday (September 18, 2026) in Grand Junction.ย 

โ€œWe canโ€™t run from it โ€” we have to learn from it,โ€ said Andy Mueller, the districtโ€™s general manager, during the event, which was held at Colorado Mesa University.

Communities and entities made sacrifices to ensure the regionโ€™s water needs were met. Reservoirs, such as Ruedi Reservoir east of Basalt, have been drawn down at faster rates than normal, municipalities have led water conservation campaigns and farmers across the valley have needed to settle for significantly smaller crop yields…The river district has for years sought the means to buy from Xcel Energy the Shoshone water rights, the oldest and largest non-consumptive water rights on the Colorado River. In acquiring the rights, the river district would prevent any other potential buyers from diverting the water from Western Slope communities…The agency has raised about $97 million of $99 million for the acquisition, $40 million of which comes from federal funds. Those federal dollars, which were secured by the stateโ€™s Democratic senators under the Biden Administration, were frozen in 2025 under the Trump Administration. Earlier this year, U.S. Rep. Jeff Hurd, R-Grand Junction,ย worked successfully to release the funds.

โ€œThatโ€™s the kind of collaboration we need in Congress and in our communities,โ€ Mueller said…

Mueller said the stateโ€™s future water security depends on finding sustainable systems to manage the water it has now.

โ€œHow can we adapt to uncertainty and rising temperatures and reduced streams?โ€ he asked. โ€œWe donโ€™t need to argue about whether or not thatโ€™s happening. We need to focus on the future and figure out solutions.โ€

#ColoradoRiver District Annual Seminar September 18, 2026 #CRD2026 #COriver #aridification

Seminar day did not include an EV element. I ride my bicycle from Fruita to Grand Junction along the Colorado Riverfront Trail. The 14 mile ride has great views of the Colorado National Monument, Grand Mesa, and Mt. Sentinel.

Colorado National Monument from the Colorado Riverfront Trail near Fruita September 18, 2026.

Of course the Colorado River is front and center and it was so gratifying to see the river running with sediment.

It had been rainy all week in western Colorado and you could tell, it was enough to get near average streamflow at the Utah line.

My main takeaway from the seminar was that West Slope water users shared supplies to get through these rough times. Collaboration was mentioned several times as was, “We didn’t call anyone out.”

Denver Water can finish and fill Gross Reservoir, US appeals court rules — Michael Booth (Fresh Water News) #ColoradoRiver #BoulderCreek #SouthPlatteRiver #COriver #aridification

September 17, 2026

Denver Water can finish its Gross Dam expansion and fill the controversial reservoir in western Boulder County, the 10th U.S. Circuit Court of Appeals ruled Tuesday, lifting an injunction by a lower court judge and confirming the damโ€™s permits as sound.

The appeals court said the U.S. Army Corps of Engineers had acted responsibly in issuing construction permits for the $600 million expansion, which is largely complete and will be filled using water rights Denver holds in the Colorado River basin on the western side of the Continental Divide.

A federal district judge in Denver had issued the injunction after declaring the Corps had failed to consider less-damaging alternatives, or the fact that climate change could dramatically reduce the amount of Colorado River water available to fill the storage pool. But the appeals court rejected that view.

โ€œWe do not think the Corpsโ€™s choice of cost methodology was arbitrary or capricious,โ€ the appeals court ruling said. The plaintiffs, including nonprofit Save the Colorado, argued the Corps rejected clear evidence of climate change, but the appeals court ruled the Corps gave the research fair consideration.

โ€œThe Corps considered โ€” and rejected โ€” the reliability of that and similar studies, one of which showed that in the Colorado River Basin, โ€˜no consistent trends in annual precipitation have been detected over the last 100 years,โ€™โ€ the appeals court said.

โ€œIn the end, the environmental groups ask us to substitute our judgment for the Corpsโ€™s. They point out scientific studies that, in their view, rebut the Corpsโ€™s reading of the scientific literature and ask us to opine on what the scientific research establishes,โ€ the appellate ruling said. โ€œBut our job is not to second-guess the Corpsโ€™s assessment as long as it rests on a reasoned basis.โ€

Denver Water said it looked forward to completing a crucial water supply project it began permitting 23 years ago.

โ€œWeโ€™re pleased to see the 10th Circuit Court of Appeals confirm that the Gross Reservoir Expansion Project was lawfully permitted by the U.S. Army Corps of Engineers and that Denver Water can proceed with the final stages of this critical project to ensure a safe, secure water supply for the 1.5 million people we serve,โ€ according to a statement from spokesperson Todd Hartman. โ€œWith this decision, Denver Water can move forward with completion of construction, site preparation and eventual filling of the expanded reservoir. An expanded Gross Reservoir is vital to the future of the Denver region.โ€

Save the Coloradoโ€™s Gary Wockner, who has led battles against many projects threatening to further alter the ecology of Colorado river systems, said the appeals court decision doesnโ€™t change Coloradoโ€™s water challenges.

Itโ€™s nonsensical to be putting more straws in, and further draining, the Colorado River at this point in history,โ€ Wockner said. โ€œThat the law allows it to happen doesnโ€™t make it right, it just makes it legal. I saw something wrong, I stood up, spoke out and took action. It was the right thing to do and I would do it all over again.โ€

Wockner said Tuesday the plaintiffs would not be appealing the decision to the U.S. Supreme Court.

Gross Reservoir Dam backs up South Boulder Creek, while also taking in water through the Moffat Tunnel under the divide, from the Fraser and Williams Fork rivers in the Colorado River basin. Denver Water has said the expansion is needed to balance its water storage system currently heavily concentrated on the southern end of the metro area.

๐ŸŒจ๏ธ๐Ÿšฃ๐Ÿฝ WATER WATCH ๐ŸŒŠ๐Ÿฆฆ

The Trump administrationโ€™s Environmental Protection Agency is proposing to further constrain the reach and potency of the Clean Water Act by re-defining what qualifies as โ€œwaters of the United States,โ€ or WOTUS, which are streams, wetlands, and other water bodies under federal jurisdiction. The proposed definition would disproportionately affect the arid West by lifting protections from thousands of miles of streams, arroyos, and wetlands.

Under the CWA, a firm or individual looking to discharge pollutants or other material into, or dredge or reroute or otherwise alter, a WOTUS waterway must obtain a federal permit from the EPA or Army Corps of Engineers. A battle has raged for more than five decades over what constitutes a WOTUS. The Supreme Courtโ€™s 2023 Sackett v. Environmental Protection Agency ruling called for a narrower definition, handing industry and right-wing ideologues a major victory.

Ephemeral streams are streams that do not always flow. They are above the groundwater reservoir and appear after precipitation in the area. Via Socratic.org

The changes in the latest proposed supplemental rule are even more exclusionary than the administrationโ€™s November 2025 proposal, which removed โ€œephemeralโ€ and โ€œintermittentโ€ waterways โ€” i.e. arroyos or washes that run only after rains or snowmelt โ€” from federal jurisdiction. Included as a WOTUS under that proposal were โ€œrelatively permanent โ€ฆ bodies of surface water that are standing or continuously flowing year-round or at least during the wet season.โ€

The new proposal omits the โ€œwet seasonโ€ verbiage. It then defines โ€œrelatively permanentโ€ to be synonymous with โ€œperennial,โ€ which in turn is defined as โ€˜โ€˜having standing or continuously flowing water every day of the year during ordinary conditions.โ€™โ€™ However, โ€œa body of water does not lose its relatively permanent status if it dries up as a result of anomalous events such as drought or dry spell.1 A body of water also does not lose its relatively permanent status if it dries up for no more than a single period of up to 30 consecutive days in any given year as a result of non-anomalous events resulting in a temporary interruption such as low tide or a regularly occurring dry spell.โ€ Yet, โ€œif flow is interrupted for two periods in any given year, and each period consists of 10 consecutive days of no flow, the water body would not be jurisdictional.โ€

A Natural Resources Defense Council analysis found that the new proposal would remove protections from more than 94% of the nationโ€™s wetlands and about 79% of its streams. The changes would hit the West hardest, leaving a state like Arizona with almost no federally protected streams or wetlands.

So hereโ€™s my interpretation of where the updated proposal leaves us:

  • WOTUS waterways (keeps CWA protections): A year-round river, stream, or lake that never dries up, such as the Animas River, the San Juan River, the Colorado River, the Gunnison River, Cement Creek, Mineral Creek, the Fremont River, and so on, would retain federal protections under the CWA. However, since most of these rivers are fed by intermittent or ephemeral streams, they would also be potentially affected (since is someone altered or polluted a tributary, the effects would eventually reach the mainstem).
  • Non-WOTUS waterways (would lose CWA protections): All intermittent and ephemeral streams, i.e. arroyos or washes that run only when it rains, such as are ubiquitous in the arid West, would be removed from federal jurisdiction. Other streams and rivers that run seasonally, but regularly dry up for more than 30 consecutive days per year, such as the Paria River, the Dirty Devil, Rio Puerco, Santa Cruz River, or the Mancos River, would also lose federal protections, as would wetlands that are only โ€œwetโ€ for part of the year.
  • Vague WOTUS status: Rivers or streams that are perennial as a whole, but on which certain segments dry up for more than 30 days per year (usually because of upstream diversions), e.g.: the Rio Grande through Albuquerque, long sections of the Lower Dolores River between McPhee Dam and its confluence with the San Miguel, the North Fork of the Gunnison around Paonia, lower reaches of the La Plata River, or Junction Creek through Durango, and numerous desert rivers in Arizona and New Mexico.

While the proposed rule would remove federal CWA protections from many waterways, it would not automatically give developers or industry free rein to bulldoze or dump toxic waste into them. State and local laws would still apply, and arroyos and streams on public land would still be protected to some degree by federal environmental laws. Colorado lawmakers passed a bill in 2024 that effectively backfilled the regulatory gap left by the Sackett decision. New Mexico also has moved to implement its own layer of water protections. In more industry-friendly states such as Idaho and Utah, the proposed rule would leave thousands of miles of streams and waterways vulnerable to development and pollution.

๐ŸŸ Colorado River Chronicles ๐Ÿ’ง

A new paper is out from the group of Colorado River experts known by some as the โ€œTraveling Wilburys of the Colorado River Basin,โ€2 and lo and behold, it actually contains some good news. Namely this: The Lower Basin users have managed to make significant reductions in water use over the last decade and a half without turning the Southwest into a dust-choked wasteland and getting ahead of the latest round of mandated cuts. This indicates that the users can continue to slash water use in the future โ€” to a degree โ€” if necessary. 

The Lower Basin accounts for about 60% of all consumptive water uses and losses on the Colorado River. Irrigated agriculture, in turn, makes up about 60% of the Lower Basinโ€™s consumptive use. The Imperial Irrigation District, which is primarily agricultural, is the largest single water user on the entire river. This means that the agricultural sector โ€” and the IID in particular โ€” โ€œwill play a significant role in future reductions in water use,โ€ as the authors put it.

So far, the Lower Basinโ€™s farmers and the IID have stepped up. In 2025, the Lower Basin statesโ€™ consumptive use was 5.76 million acre-feet, the lowest since at least 2010. Since 2023, California has used about 13% less water, a reduction attributable mostly to cuts at IID.

Source: The Colorado River Water Supply Crisis in a Few Graphs: Part 2 Agricultural Water Use in the Lower Basin.
Figure 3. Consumptive use in Arizona since 2010. Estimated use in 2026 based on forecast of September 1, 2026.

Notably, IIDโ€™s reductions came mostly during the summer months, the peak season for field crops such as alfalfa, Bermuda grass, and kleingrass, when itโ€™s too hot to grow most garden crops, such as lettuce, onions, and broccoli. During the vegetablesโ€™ growing season, from November through March, water use stayed roughly the same as before. A similar, but less dramatic, dynamic shows up in Arizona.

Figure 6. Box-and-whisker plots of total monthly consumptive use by the IID between 2010 and 2026. Each box is the Inter Quartile Range, defined by the 25th and 75th percentile of the years of data for that month. These boxes represent the typical monthly use pattern since 2010. Red dots are the average use in each month between 2024 and 2026. See text for additional explanation of a box-and-whisker plot.

This suggests a couple of things: 1. The Imperial Irrigation District and other large agricultural users may be able to significantly lower overall water use without harming important garden crops such as broccoli and carrots (easing fears that the Colorado River crisis will deprive us of vegetables); and, 2. The IID is successfully using its vast alfalfa crop as a giant water demand-response tool3. That is, through both fallowing some fields and putting others on a summer water diet, the districtโ€™s farmers have managed to slash water use, while still growing gobs of hay and alfalfa. 

And because the IID still has about 150,000 acres of alfalfa, it has huge potential for future water cuts through these same methods, which is the good news. The bad news is that the federal plan for operating the river contemplates Lower Basin cuts of up to 3 million acre-feet per year (resulting in a total annual consumption of 4.5 MAF), which is about twice what the Basin has already achieved.

To consider the viability of such cuts, the authors summed up the smallest monthly use in each Lower Basin state since 2010, even though they didnโ€™t occur simultaneously, and even though in some cases the reductions were due to heavy precipitation, not conservation efforts. The result was 5.03 MAF, still 530,000 acre-feet over the potential target. In other words, getting to 4.5 MAF/year is likely to be much more painful than accomplishing the reductions so far. 

Yet some pain is likely to be necessary unless the Westโ€™s warming climate does a rapid about-face, and soon.

1 * The proposed rule says โ€œonly extreme (D3) and exceptional (D4) droughts would qualify as anomalous drought conditions that can temporarily interrupt perennial flow, and can extend continuously across no more than a five-year timeframe.โ€

2 This is an appropriate monicker, coined by longtime Colorado journalist Allen Best, and is great for those of us in Generation X or older. But I worry that it might not mean much to anyone under the age of, say, 40? So if you have any more contemporary suggestions for a group of superstar water wonks, aka, Jack Schmidt, Anne Castle, Eric Kuhn, Kathryn Sorensen, and Katherine Tara, Iโ€™d love to hear them!

3 Demand response is a term typically used in relation to electricity use. Itโ€™s when large power users, or a collection of smaller users, are paid to reduce electricity consumption during times of high demand to ease grid strain. So, for example, during a heat wave, when everyoneโ€™s air conditioners are running full blast, the utility or grid operator would signal a factory, say, or a data center, or even a host of smart thermostats, to scale back their operations or dial down the AC during the hottest time of the day when solar generation might be dropping off. The targeted drop in consumption has the same effect as increasing power generation would, keeping supply and demand in balance.

Since Jonathan wonders if anyone under 40 will get the reference to the Traveling Wilburys, here you go:

At #GlenCanyon Dam, the Trump Administration Privileges #Hydropower over Ecosystems: #GrandCanyon ecology not a priority in 2026 water release decisions — Brett Walton (circleofblue.org) #ColoradoRiver #COriver #aridification

September 16, 2026

In the struggling Colorado River basin, where water is scarce, the White House has signaled its priorities for how to use the remaining gallons.

Even as scientifically-determined thresholds have been met for releasing water from Glen Canyon Dam for ecological and recreational benefits in Grand Canyon, the Trump administration has decided against those actions in this record-hot year โ€“ deciding not to release cold water from deep in Lake Powell to aid the humpback chub, a threatened fish species, and not to authorize a high-volume release of water to rebuild Grand Canyonโ€™s eroded beaches, which are in terrible condition, according to federal monitoring.

These environmental releases would not change the total volume of water flowing out of Lake Powell over the year, just the timing.

Because the releases bypass the damโ€™s turbines and reduce hydropower generation, which is part of the administrationโ€™s โ€œenergy dominanceโ€ agenda, the Bureau of Reclamation, the federal agency that manages Glen Canyon Dam, will not be doing them.

โ€œAfter evaluating management alternatives and considering all authorized purposes, the decision was made based on significant hydropower generation concerns under already strained system conditions,โ€ Reclamation said in a statement in August.

The administrationโ€™s decisions foreshadow more difficult choices ahead. Due to climate change and overuse, the Colorado River is shrinking and warming. Its dams were built and river management goals were laid out during an era that anticipated healthy reservoirs. That is no longer the case. Because Lake Powell and Lake Mead are about a quarter of their capacity or less, the hydrological assumptions that inform current management strategies are outdated, said Jack Schmidt, a scientist who has spent his four-decade career studying the Colorado River.

โ€œEverything needs to be revisited because the driving factors of the Colorado River ecosystem in Grand Canyon are now completely changed and probably forever changed,โ€ said Schmidt of Utah State Universityโ€™s Center for Colorado River Studies. โ€œEverything was developed in a world of full reservoirs. And now the reservoirs are empty.โ€

Tradeoffs Plague Water Managers

Even in the best of times, managing a large dam on a major river is not easy. Dams alter the riverโ€™s natural patterns of flow and temperature. Operators must weigh one set of benefits against another group of costs.

Glen Canyon Dam is one of the thorniest management conundrums. Located near the Arizona-Utah border, the 63-year-old structure has emerged as the most significant water-supply choke point in the Colorado River basin and it is the focus of clamorous debate about water and power infrastructure in a drier climate.

As managers grapple with how much water to release, Glen Canyon Dam is also choking the river of its natural supply of sediment. Without new inputs, sand bars and beaches in Grand Canyon are at risk of disappearing. These features provide habitat, give boaters a place to camp during river trips, and protect archaeological sites.

Most of the riverโ€™s sediment now comes from the Paria River and Little Colorado River, downstream of Glen Canyon. Periodic high-flow water releases from the dam mimic the thunderous floods of the past that carried sediment through Grand Canyon to fortify eroding beaches.

There is enough sediment in the Colorado River below Glen Canyon today to warrant a high-flow release. Yet Reclamation has not done one since 2023. Experts agree that Reclamation is highly unlikely to conduct one this fall either. A final decision will be made in the next few weeks.

The need for a high-flow release is mounting. In August, David Topping, a research hydrologist at the U.S. Geological Surveyโ€™s Grand Canyon Monitoring and Research Center, presented data showing the ill health of Grand Canyon beaches. A typical sand bar is smaller now than in 2016, when the current management plan that established the high-flow triggers was finalized.

The lack of high-flow releases has deprived researchers of crucial data on how the size and duration of these mini-floods, usually one to four days in length, aid beach-building.

โ€œWhat can we do if the administration isnโ€™t willing to allow us to use the bypass tubes for high-flow experiments, if thatโ€™s going to be off the table, at least for a while?โ€ said Wayne Pullan, Reclamationโ€™s Upper Colorado Region director, at a Glen Canyon management meeting in August, asking attendees to consider management options under political constraints.

โ€œWeโ€™re in a pinch point,โ€ Pullan added. โ€œA real pinch point.โ€

Degraded beaches result in a degraded river experience, said David Brown of the Grand Canyon River Guides, a recreation advocacy group. Rafting groups have to compete for limited real estate in what is generally regarded as one of the worldโ€™s premier river corridors.

โ€œWhen thereโ€™s less campable area, that means everyoneโ€™s kind of getting squished together or your toilet is next to where people are sleeping,โ€ Brown said.

Non-Native Species Thrive in Warm Water

In addition to sediment, water temperature is the other blinking red environmental indicator.

Air temperature records in the basin are being obliterated this year. Colorado, home to the riverโ€™s headwaters, had its hottest summer ever. Scorching air temperatures are reflected in water. The Colorado River below Lake Powell is the warmest since Glen Canyon Dam was completed.

Smallmouth bass were introduced as a sport fish in the upper Colorado River basin in the late 1960s. Voracious feeders, smallmouth bass view other fish as the sport, happily preying on threatened native species like the humpback chub, an eighteen-inch fish in Grand Canyon with a distinctive smooshed silhouette.

Listed as endangered in 1967, the humpback chub has now bounced back thanks to tens of millions of dollars of conservation investment. The U.S. Fish and Wildlife Service upgraded the humpback chub to โ€œthreatenedโ€ status in 2018.

Smallmouth bass live in Lake Powell, preferring the layer of warm water closest to the surface. As the lake shrinks, that warm layer has now reached the level of the penstocks, which pull water into Glen Canyon Damโ€™s turbines for hydropower generation before being released downstream.

In these low-water conditions, the fear is that more smallmouth bass will be delivered into the Colorado River below Glen Canyon.

Once there, they will find a habitable environment. Smallmouth bass spawn when water temperatures exceed 60 degrees Fahrenheit. This year, that mark was breached in June. Today, the river at Lees Ferry, about 16 miles downstream of Glen Canyon Dam, is about 70 F.

These conditions โ€“ when the river temperature is above 60 F for three consecutive days โ€“ are supposed to trigger a release of cold water from deep in Lake Powell. The U.S. Fish and Wildlife Service says that this โ€œcool mixโ€ is the โ€œonly conservation measure proven to limit smallmouth bass reproduction.โ€ Evidence from cool mix releases in 2024 and 2025, which knocked down smallmouth bass numbers, supports that conclusion.

Cool mix, however, will not happen in 2026 due to the Trump administrationโ€™s desire to generate hydropower.

The last cool mix flow, in 2025, cost the Western Area Power Administration, which markets federal hydropower, $6.1 million to replace that electricity for its contractors.

Instead of cool mix, Reclamation says it is focusing on other options to keep smallmouth bass from establishing downstream of Glen Canyon and to preserve the humpback chubโ€™s hard-won conservation gains. In the short term that means stunning the bass with electric-shock tools and physically removing them from the water.

In the longer term, Reclamation is considering installing infrastructure to regulate the temperature of the water that passes through Glen Canyon. The agency calls this one of its โ€œdurable structural solutions.โ€

An Uncertain Future

Cool mix and high-flow releases are an attempt to rebalance an ecosystem that the dams destabilized. Congress passed the Grand Canyon Protection Act of 1992, which orders Reclamation to operate Glen Canyon Dam in a manner that protects and reduces harm to the โ€œnatural and cultural resources and visitor use.โ€ That is, fish, tribal archaeological sites, and rafting.

The act required an environmental impact statement for Glen Canyon Dam that would analyze the actions required to achieve the broad environmental-protection goals set by Congress.

It was a โ€œcompromise to really put all the resources on the same playing field,โ€ said Jen Pelz of the Grand Canyon Trust. In her view, decisions this year tilt in one direction โ€“ hydropower. โ€œI donโ€™t feel like theyโ€™re being balanced right now.โ€

Because the river guides were instrumental in lobbying for Grand Canyon protections, the present-day failures to uphold the actโ€™s goals are all the more galling, Brown said. โ€œItโ€™s very hard to watch it get ignored.โ€

The administration is prioritizing hydropower when hydropower is at a pivot point.

Generation at Glen Canyon is down more than 40% from when Lake Powell was full. Utilities are turning to solar and wind to cover some of the generation losses, while utility-scale batteries are helping to replace the capacity and grid-regulating functions that a large dam provides.

The decision to favor hydropower over ecology reflects bigger problems with the Colorado Riverโ€™s infrastructure. Glen Canyon Dam is not designed for the river as it exists today. Reclamation wants to keep Lake Powell high enough to generate hydropower because the damโ€™s other outlets to deliver water downstream are untested over long periods and were damaged in a previous high-flow release.

Lower basin states and tribes, including Arizona, California, Nevada, and the Gila River Indian Community, have asked the federal government to update Glen Canyonโ€™s infrastructure for water delivery and power generation. Reclamation is assessing three options and expects that study to be released in early 2027. Any additional action will require congressional approval and funding.

Along with the infrastructure problems, man-made climate change is sapping the river and heating up its water. Ecologists consider the Grand Canyon a โ€œnovel ecosystem,โ€ meaning its native species and natural processes have been disrupted and rearranged by human meddling.

To Schmidt, the former chief of the U.S. Geological Surveyโ€™s Grand Canyon Monitoring and Research Center, this suggests a wholesale rethinking not just of the riverโ€™s infrastructure but also of our ecological goals for the Colorado River.

โ€œWe as a society get to play God in deciding what attributes of that ecosystem we value, which ones we want to work hard to preserve and which ones we donโ€™t,โ€ he said. โ€œThe answer is not an obvious one.โ€

๐Ÿฆซ WILDLIFE WATCH ๐Ÿฆ…

Just days after President Donald Trump angered U.S. ranchers by waiving tariffs on 300,000 metric tons of foreign beef (and whatever other meat-adjacent-material may pass as beef), he threw the livestock industry a bone by ordering a โ€œreviewโ€ of federal Endangered Species Act protections for gray and Mexican wolves. The order also instructs the Interior Department to push states into removing any state-specific protections and to โ€œrevise their standards for lethal takings of gray wolves and Mexican wolves to assist ranchers in combating predation.โ€

In other words, Trump wants to revive the late 19th and early 20th century campaign to exterminate wild predators to benefit ranchers. Will this please a handful of public lands livestock operators who are ideologically inclined to hate wolves, whether they affect their operations or not? Sure. Will it save the American rancher, or even offset the influx of foreign beef? Nope.

Wolves do kill cattle if they are not adequately protected (and the rancher is compensated for the lost livestock), and they can have other impacts on ranching operations in wild areas. But study after study has shown that other factors โ€” from weather and climate, to sickness and disease โ€” account for a far greater share of cattle and calf mortalities.

This is the administrationโ€™s latest ploy in its quest to boost the number of cattle on public lands. It is also peddling vacated grazing allotments and easing the already decidedly lax regulations on grazing.

๐ŸŸย COLORADO RIVER CHRONICLESย ๐Ÿ’ง

The irrigation canals, laterals, and ditches are going dry in the Colorado Riverโ€™s Upper Basin weeks before the growing season comes to an end, forcing farmers to rely on September rains or their own storage to get their crops to harvest time. It goes to show that even without mandatory cuts, many Upper Basin water users experience water shortages during dry years.

The biggest and latest user to get cut off by low river flows was the Grand Valley Water Users Association, which began drawing down its Government Highline Canal as โ€œthe river flows drop to undeliverable levels.โ€ Flows in that canal fell from almost 1,500 cfs at the end of August to about 725 cfs early this week. The more senior Orchard Mesa Irrigation District and Grand Valley Irrigation Company continued to pull water from the river and deliver it to irrigators.

In the North Fork Valley, all but the most senior ditches were shut off weeks ago, after Paonia Reservoir hit dead pool. And on the Dolores River, even the most senior water rights holders โ€” the Montezuma Valley Irrigation District โ€” lost their water at the beginning of this month. Usually it holds out for at least another couple of weeks. (Other water users received dramatically curtailed amounts throughout the irrigating season).

In the Grand Valley, the canalโ€™s loss was the riverโ€™s gain: The Colorado River near Palisade, after running as low as 42 cfs this summer, bounced back to around 300 cfs at the end of August. A corresponding increase in flow can be seen at the USGS gage1 near Cisco. This little boost, combined with a few intense, but patchy storms, and a slight increase in releases from Flaming Gorge Reservoir, have brought up inflows into Lake Powell, somewhat slowing the drop in surface levels.

The Dolores River, on the other hand, remains virtually dry downstream of McPhee Dam, and McPhee Reservoirโ€™s surface level is currently about 12 feet lower than it was a year ago.

๐Ÿ“ˆย TODAYโ€™s DATAVIZย ๐Ÿ“Š

Are coal and electricity consumption getting back together? For the latter half of the 20th century, U.S. coal consumption climbed in tandem with electricity demand: As Americans used more power, more coal was burned to generate that power, and vice versa. In 2008, electricity demand plummeted due to the financial crisis, dragging coal consumption down with it. 

While electricity demand rebounded along with the economy, and then plateaued, coal-burning continued dropping precipitously; the two phenomena had been decoupled from one another. But over the last three years electricity demand has shot back up, in large part due to data centersโ€™ guzzling up a lot of power, but also because of electrification of transportation and buildings, and an increasing need for air-conditioning to fend off rising temperatures. And last year the electric power sectorโ€™s coal consumption shot back up as well. Is the decoupling being undone? Or is this just a minor blip? Only time will tell.

Hay meadows in pristine #Colorado river basins put to work as water-quality test labs — Jerd Smith (Fresh Water News)

September 9, 2026

Colorado ranchers who own some of the stateโ€™s most scenic landscapes are joining new research efforts to better understand emerging water quality issues in the Yampa and Gunnison basins, among others.

Pressured by rising stream temperatures and shrinking flows due to climate change, rivers and lakes across the state are showing signs of distress, including algae blooms, some of which are toxic.

At the same time, the Colorado Department of Public Health and Environment and Colorado State University are analyzing water quality and testing how voluntary best management practices, rather than strict regulations, can protect these hallmark water bodies.

Philip Rossi grows hay and runs a cattle operation in the Upper Yampa River Basin above Stagecoach Reservoir. He is among the first ranchers to agree to allow scientists to monitor the water quality, and soon the temperature, of the irrigation water that runs off from his hay meadows.

So far the news has been good, Rossi said. Little if any of the fertilizer he applies to his hay reaches the stream and in the years heโ€™s been working with the CSU researchers, the use of nonfertilized grass strips along the creek that runs through his property has reduced that number even further.

โ€œWhat I learned is that I wasnโ€™t wasting money. The fertilizer I was putting on was being used, and just as important I wasnโ€™t affecting the stream.โ€

With results from the first three-year study officially out, another even broader effort involving more ranches is underway. It will add the monitoring of stream temperatures to the analysis.

Erik Wardle, director of Colorado State Universityโ€™s Agricultural Water Quality Program, said there was little water quality data available in remote regions such as the Yampa Basin. โ€œWe wanted some real world data on whatโ€™s happening on our ranches and our cow-calf operations.โ€

As word of the research has spread, more ranchers have come forward to participate, despite skepticism and worry about government efforts to monitor what theyโ€™re doing. โ€œEarly on I was doing a lot of cold calling, asking ranchers to participate. And a lot of them said, โ€˜Are you crazy?โ€™ But now I would say 85% of what weโ€™re doing is being driven by these producers. These ranchers have put themselves out there,โ€ Wardle said.

Even in these pristine areas of Colorado, no one expects water quality worries to subside in the warmer future. In response, water agencies in the area are looking for ways to change the way they operate to help streams.

โ€œWater quality on the West Slope has always been assumed to be great,โ€ said Andy Rossi, general manager of the Upper Yampa Water Conservancy District, which owns Stagecoach Reservoir. He is not related to Philip Rossi, the rancher. 

โ€œHere we are in snowpack-dominated basins with pristine wilderness areas driving our water supply. But 10 years ago we started seeing changes, like toxic algae blooms in Stagecoach Reservoir and Steamboat Lake.โ€

Since then, the water district has shifted into high gear to understand whatโ€™s happening and why, spending hundreds of thousands of dollars to build a water quality modeling and monitoring program.

Nothing that has been uncovered yet has exceeded a state standard, Rossi said, โ€œyet we still have potentially toxic algae blooms. The assumption has always been that ag is the source of our troubles. But we felt it was unfair to jump to that conclusion without doing the strict science to figure it out.โ€

Can best practices be shared between ranches?

With early research results in hand, Tyson Ingels, a veteran water quality regulator at the Colorado Department of Public Health and Environment, said the state hopes to avoid a strict regulatory approach for these remote high country lakes and streams, relying on voluntary efforts instead.

โ€œThis is a very positive study,โ€ he said. โ€œFor mountain hay we didnโ€™t have the best data on how best management practices could impact nutrient levels. This was an area that needed to be better understood.โ€

Looking ahead, Ingels said the state wants to take a measured approach to these regional water quality issues. That the best management practices that are being used on the Rossi Ranch and elsewhere are working well indicates that water quality goals can likely be achieved without a heavy-handed regulatory effort.

Philip Rossi said heโ€™s feeling optimistic, in part because of all the scientific groundwork that is being laid, as well as the early encouraging results of the studies.

He believes that the temperature studies of the water that is returning to the streams, will also show minimal impact.

The rationale, he said, is that water used to flood irrigate fields seeps into the groundwater, flowing to the stream later, when it has cooled down. This was the belief held by his father and grandfather, and Rossi believes the new studies will uphold those beliefs. โ€œThe researchers are going to find out the things that my dad told me and that my grandpa used to sayโ€ are true, he said.

Aspinall Unit Operations Update โ€“ Ramping down Gunnison Tunnel diversions, variable river flows through the Black Canyon #GunnisonRiver

From email from Reclamation (Andrew Limbach):

On Monday, September 14th at 8:00 AM (MDT), the UVWUA will begin ramping down tunnel diversions to 675-700 cfs. In coordination with that effort, Crystal releases will decrease to 875-900 cfs from 1240 cfs, and flows through the Black Canyon will be between 200-225 cfs. Tunnel diversions are anticipated to be at 700 cfs through October 31. 

The Crystal outlet works typically experiences increased levels of cavitation between 900 and 1200 cfs. Therefore, Crystal releases may need to be adjusted as needed to find an optimal operating zone. Recreators and boaters in the Black Canyon should expect fluctuations of river flows until the final releases and diversions are set. Another notification will be sent out once the releases are finalized.
