January 27, 2026

As Colorado continues to negotiate with the seven Colorado River basin states on the post-2026 operations of Lake Powell and Lake Mead, the stateโ€™s attorney general and lead negotiator are ready for a legal battle if the states continue to clash.

โ€œIf it comes to a fight, we will be ready,โ€ said Becky Mitchell, the Colorado River commissioner, who represents the state on the Upper Colorado River Commission, at the Jan. 23 SMART Act hearing for the Colorado Department of Natural Resources, where the agency provided its annual update on priorities and programs to lawmakers. 

After two years of back and forth, Colorado River basin states remain deadlocked, unable to agree on the guidelines for how Lake Powell and Lake Mead should operate beyond 2026. The operations of these two critical reservoirs have widespread implications for the approximately 40 million people, seven states, two counties and 30 tribal nations that rely on the river…In Colorado, the Colorado River and its tributaries provide water to around 60% of the stateโ€™s population.ย 

โ€œWe developed priorities that continue to serve as my north star as we negotiate these post-2026 operational guidelines,โ€ Mitchell said. โ€œThe most important of these priorities is to protect Colorado water users. This means that our already struggling water users and reservoirs cannot be used to solve the problem of overuse in the lower basin.โ€ย 

[…]

Despite disagreements over how the reservoirs should operate in an uncertain future, reaching a consensus between the seven Colorado River basin states remains the objective for all involved, but time is ticking.ย  The U.S. Bureau of Reclamation โ€” which manages Lake Powell and Lake Mead โ€” has given the states until Feb. 14 to reach an agreement before the federal agency steps in and makes the decision itself.ย  Mitchell told lawmakers that she was still โ€œoptimisticโ€ about reaching a consensus by the deadline, adding that she will โ€œsit in the room with the full intent to negotiate,โ€ as long as there are โ€œwilling parties.โ€ย 

โ€œFolks should start worrying when Iโ€™m no longer in the room,โ€ she said. โ€œI will, 100%, be focused on a deal until thereโ€™s not a deal to be had.โ€

๐ŸŒต Public Lands ๐ŸŒฒ

If youโ€™ve ever floated the Gunnison River in western Colorado through the Dominguez-Escalante National Conservation Area between Delta and Grand Junction, youโ€™ve probably noticed that the land on either side of the stream alternates between public parcels and private ranch land. If the Bureau of Land Management has its way, some 4,000 acres of that private land will soon be entering the public domain, according to reporting from the Grand Junction Daily Sentinel. Thatโ€™s right, the agency is putting more lovely land into the publicโ€™s hands. 

The parcels were formerly operated as a ranch by Dick Miller. After he died, the Conservation Fund purchased the land from Millerโ€™s son for an undisclosed amount in order to sell it to the BLM. The associated BLM grazing leases will reportedly be transferred back to the BLM, but it isnโ€™t clear whether theyโ€™ll be made available for grazing again.


The BLM is also looking to put a lot of public land into oil and gas companiesโ€™ hands. The agency is seeking public input on proposals to lease 74 parcels covering 33,530 acres in New Mexico, and 271 oil and gas parcels totaling 357,358 acres in Wyoming

The New Mexico parcels are mostly in the Permian Basin, but do include tracts in the San Juan Basin located north and northeast of Chaco Culture National Historical Park (but not within the ten-mile buffer zone, which remains in place โ€” for now). 

The Wyoming parcels are concentrated in the southern part of the state between Rawlins and Green River, the central part of the state, and the Powder River Basin.

๐Ÿฆซ Wildlife Watch ๐Ÿฆ…

Wolves in the West have had a rough go of it ever since white settlers showed up in the 1800s and proceeded to slaughter them en masse. And while theyโ€™ve been able to recover somewhat in the Northern Rockies, thanks in part to endangered species protections and reintroduction efforts, the move to bring them back to Colorado and the Southwest has hit obstacles โ€” and tragedy, including:

  • Another reintroduced wolf has died in Colorado, reports the Colorado Sunโ€™s Tracy Ross, bringing the total number of wolf fatalities since the start of reintroduction to 11. The cause of death has not been determined.
  • Meanwhile, Colorado Parks and Wildlife has paused new wolf reintroductions because it hasnโ€™t been able to find another state or tribal nation to provide the animals.
  • Utah Department of Agriculture officials killed three wolves in the northern part of the state on Jan. 9. While wolves are protected by the Endangered Species Act in most of the state, they were delisted in one small section along the Wyoming border when protections were lifted for the Northern Rockies population. Now, apparently, the state will kill any wolves that wander into that area, just because they can, and to prevent them from going into the protected zone. Thatโ€™s despite the fact that the three animals had not killed or stalked any livestock. โ€œI have not heard any of my neighbors, and we havenโ€™t had the experience ourselves that weโ€™ve had actual issues with our cattle and wolves,โ€ area livestock owner Launie Evans told KSL.
  • And in more sad news: โ€œTaylor,โ€ the Mexican gray wolf that wandered out of southern New Mexico and into the Mt. Taylor region, was found dead on I-40 near Grants. Taylor first roamed onto Mt. Taylor early last year, apparently not realizing that the feds donโ€™t allow wolves to cross I-40. Wildlife officials captured him and deported him back to the southland, but he was persistent, and simply turned around and headed north again. He was removed again in November, but couldnโ€™t stay away from Mt. Taylor. This time, on his return journey, he was struck by a vehicle.

    โ€œTaylorโ€™s death is a heartbreaking reminder that highways like I-40 are not just lines on a map, they are lethal barriers for wildlife,โ€ said Claire Musser, executive director of the Grand Canyon Wolf Recovery Project, in a statement. โ€œAbolishing I-40 as a management boundary is long overdue. If we are serious about recovery, we must allow wolves to move freely across suitable habitats and invest in wildlife crossings and landscape-scale connectivity so highways no longer function as death traps.โ€
  • And, finally, CPWโ€™s latest map of wolf activity is out (at the top of this section), and it shows that wolves have been wandering into new parts of the state. Folks in the Silverton area might just be seeing some soon. If you think you see one, but arenโ€™t sure if itโ€™s a wolf or coyote, this little guide from CPW might help:

โ›๏ธ Mining Monitor โ›๏ธ

Public Citizen just released an accounting of some of the ways the Trump administration is subsidizing global mining corporations and their operations on public lands โ€” and the ways in which executives made off like bandits as a result. Itโ€™s worth reading the whole report, but here are just a small sampling of highlights:

  • $8.8 million: Amount 13 mining corporations, including Rio Tinto, Resolution Copper, South32, Lithium Americas, and Ambler Metals, spent on lobbying in 2025.
  • $3.5 million: Amount Lithium America paid Interior Department official Karen Budd-Falenโ€™s husband for water rights for its Thacker Pass mine in Nevada. The federal government also took a 5% stake in the company and the mine as a condition of preserving a Biden-era loan.
  • $400 million: Amount the U.S. Defense Department paid for a stake in Las Vegas-based MP Materials, which owns the Mountain Pass rare earths mine in California. The Pentagon also loaned the company $150 million.

The Bureau of Land Management approved the Grassy Mountain gold and silver mine on 469 acres of public land in Malheur County, Oregon. The action allows Paramount Gold Nevada to develop an underground mine, an onsite mill, and โ€œassociated storageโ€ (which Iโ€™m taking to mean theyโ€™ll be able to dispose of toxic mill tailings on public land mining claims).

January 31, 2026

Arizona Gov. Katie Hobbs and leaders of the six otherย Western states that rely on the Colorado Riverย ended a Friday meeting in Washington, D.C. with no deal to endย a stalemate over rights to the river’s dwindling water supply. Hobbs indicated that progress was made thanks to newfound flexibility from upstream states over their willingness to make commitments to cut some of their river water use, as the Lower Basin states, including Arizona, have already done. But Colorado officials all but directly contradicted Hobbs’ comments, saying they and Upper Colorado River Basin states were sticking to their position opposing any mandatory water use cuts on their part. The meeting was hosted by U.S. Interior Secretary Doug Burgum…

โ€œI was encouraged to hear Upper Basin governors express a willingness to turn water conservation programs into firm commitments of water savings,โ€ [Katie] Hobbs posted on social media after the two-hour meeting. “Arizona has been and will continue to be at the table offering solutions to the long-term protection of the river so long as every state recognizes our shared responsibility…

Mitchell said, “Colorado is committed to being part of the solution, and with our Upper Basin partners, we have offered every tool available to us. This includes making releases from our upstream reservoirs and establishing a contribution program as part of a consensus agreement. However, any contributions must be voluntary, and we have real ideas and plans to achieve the goals…”As several upper basin governors clearly stated at the meeting, we cannot and will not impose mandatory reductions on our water rights holders to send water downstream,” she wrote. “Our water users are already facing uncompensated reductions through state regulation. In many cases, these reductions impact 1880s water rights that predate the (Colorado River) Compact. Any contribution program must recognize our hydrologic realities: we simply cannot conserve water that we do not get to begin with.โ€

[…]

Mitchell spoke in even stronger terms earlier in the week at a public talk she gave in Aurora, a suburb of Denver. She spoke at the annual meeting of the Colorado Water Conference, a professional association that advocates for policies and laws that protect the stateโ€™s waters.


Upper Colorado River Commissioner Becky Mitchellโ€™s prepared remarks โ€œThis is the river we actually live withโ€ for the Colorado Water Congress Annual Convention January 28, 2026 — Coyote Gulch


โ€œFor more than a century, we built a system on optimism and entitlement. We planned for abundance, labeled it normal, wrote it in the law, and when the water showed up, we spent it,โ€ Mitchell told the gathering, in remarks reported by the Colorado Sun news website. โ€œWhen it didnโ€™t, we blamed the weather, climate change or each other. Anything but the simple math.โ€

The seven states need to tie reservoir releases more closely to the actual amount of water coming in, Mitchell said in an interview after the speech. That was a nonnegotiable for the Friday meeting, she said. Overuse by the Lower Basin is draining the system, Colorado officials say.

With the deadline to reach a water usage agreement looming, leaders from the seven Colorado River Basin states expressed cautious optimism that their โ€œhistoricโ€ meeting in Washington, D.C., will spur the compromise needed to reach a consensus.

U.S. Secretary of the Interior Doug Burgum called the meeting at the request of Arizona Gov. Katie Hobbs, after the states blew past a Nov. 11 deadline to reach an agreement. The new Feb. 14 deadline was set by the Bureau of Reclamation, which manages water in the West under the Interior Department. 

Arizona stands to see the largest cuts if the states canโ€™t reach an agreement, because its Central Arizona Project is one of the newest users of the river water, making it legally one of the first to be cut.

The Colorado River is a vital source of drinking water for 40 million people in the seven basin states, Mexico and 30 Native American tribes, and provides water for farming operations and hydroelectricity. 

One of the biggest disagreements between the Lower Basin states โ€” Arizona, Nevada and California โ€” and Upper Basin states โ€” Colorado, New Mexico, Utah, and Wyoming โ€” is over which faction should have to cut back on their water use, and by how much.

โ€œThis is one of the toughest challenges facing the West, but the Department remains hopeful that, by working together, the seven basin governors can help deliver a durable path forward,โ€ Burgum, the former governor of North Dakota, said in a statement. โ€œLooking at this as a former governor, the responsibility each of them carries to meet the needs of their constituents cannot be understated, and we are committed to partnering with them to reach consensus.โ€

The meeting in the nationโ€™s capital lasted more than two hours, Christian Slater, a spokesman for Hobbs, told the Arizona Mirror. The governors of all of the basin states attended the meeting, except for Gov. Gavin Newsom of California, who had a prior family commitment and sent California Natural Resources Secretary Wade Crowfoot in his place. 

โ€œItโ€™s actually a pretty historic meeting, and I donโ€™t use those words lightly,โ€ John Entsminger,  Nevadaโ€™s Colorado River negotiator, said. โ€œIโ€™ve been working on the river for more than 25 years, and Iโ€™ve never seen that many governors and a cabinet secretary in one room talking about the importance of the Colorado River.โ€

In a post on X Friday afternoon, Hobbs described the meeting as meaningful and productive. 

โ€œI was encouraged to hear Upper Basin governors express a willingness to turn water conservation programs into firm commitments of water savings,โ€ Hobbs wrote. โ€œArizona has been and will continue to be at the table offering solutions to the long-term protection of the river so long as every state recognizes our shared responsibility.โ€

Reaching a water usage agreement is vital to the basin states because the Colorado Riverโ€™s water supply has been in decline for around 25 years due to a persistent drought spurred on by climate change. The decline is expected to continue into the future. 

Water levels in the two major reservoirs on the river, Lake Mead and Lake Powell, have also been in decline for the last quarter century. 

โ€œOne thing is certain: Weโ€™ll have less water moving forward, not more,โ€ New Mexico Gov. Michelle Lujan Grisham said in a statement. โ€œSo, we need to figure this out. There isโ€ฏstill a lot of work ahead to get to an agreement, but everyone wants an agreement, and weโ€™ll work together to create a pathway forward.โ€

Lower Basin states want all seven states to share mandatory water cuts during dry years under the new guidelines. But the Upper Basin, which is not subject to mandatory cuts under the current guidelines, argue that they already use much less water than downstream states and should not face additional cuts during shortages.

State negotiators for both the Upper and Lower Basin have said they would prefer a seven-state agreement over alternative river management options proposed by the federal government.

Tom Buschatzke, director of the Arizona Department of Water Resources, told reporters last week that the Grand Canyon State does not like the options proposed by the federal government as they place almost the entire burden for cuts on Lower Basin states. 

The Colorado River Compact dates back to 1922, when the seven states made their initial agreement, allocating 7.5 million acre-feet of water each year to be shared by the Upper Basin states and another 7.5 million to be used among the Lower Basin states. 

In 2025, for the fifth year in a row, the federal government imposed water allocation cuts on the Colorado River  due to the ongoing drought and Arizonaโ€™s cut amounts to a loss of 512,000 acre-feet of water for the year. 

โ€œTodayโ€™s discussion was productive and reflected the seriousness this moment requires,โ€ Colorado Gov. Jared Polis said in a statement. โ€œSince 2022, Colorado and the Upper Basin states have shown up to the negotiating table ready to have hard conversations. We have offered sacrifices to ensure the long-term viability of the Colorado River and we remain committed to working collaboratively to find solutions that protect water for our state, while supporting the vitality of the Colorado River and everyone who depends on it.โ€ 

Complicating matters this year is scant snowpack in the Rocky Mountains. Small snowpack means very little runoff, the source for almost all of Coloradoโ€™s water. 

The Lower Basin states have undertaken significant conservation efforts for Colorado River water since 2014 and have reduced their consumption from 7.4 million acre-feet in 2015 to just over 6 million in 2024.

The Upper Basin states have increased their usage in the past five years, from 3.9 million acre-feet in 2021 to 4.4 million in 2024. 

Buschatzke, who attended the meeting in D.C. on Friday alongside Hobbs, has remained insistent that itโ€™s time for the Upper Basin states to do their part. Hobbsโ€™ statement indicated that the states had made some progress toward that. 

If the states canโ€™t reach an agreement and are forced to take one of the federal governmentโ€™s proposals, it will likely lead to litigation โ€” something that the states agree they would prefer to avoid. 

โ€œWe all have to keep working together,โ€ Entsminger said. โ€œWe have to find a compromise, and we have to find a way that the states stay in control of this process and donโ€™t turn it over to the courts.โ€

Last year, Arizona put a total of $3 million to its Colorado River legal defense fund, and Gov. Katie Hobbsโ€™ proposed budget for this year would put another $1 million toward that fund. 

Entsminger said that he thinks the meeting improved the chances of the states meeting  the Feb. 14 deadline. 

โ€œWhether we have a final deal on February 14 or not, weโ€™re still going to have to keep working,โ€ he said. โ€œThatโ€™s not to say I donโ€™t think weโ€™ll meet the deadline, but I do think we keep working until we have a deal, regardless of what day in the future that occurs.โ€

January 28, 2026

Fellow Coloradans,

First I want to thank Christine Arbogast and the Colorado Water Congress for allowing me to speak today. I will be brief as Amy Ostdiek will be on a panel tomorrow giving a bit more detail of the status of the negotiations. I will be heading to Washington DC with my fellow commissioners to have more discussions.

Letโ€™s start with a truth that somehow still feels radical:

The Colorado River is not broken.

We are.

The river is doing exactly what rivers do when you take too much from them for too long. It is responding to reality. And right now, for many, reality is inconvenient.

For more than a century, we built a system of optimism and entitlement. We planned for abundance, labeled it โ€œnormal,โ€ and wrote it into law. When the water showed up, we spent it. When it didnโ€™t, we blamed the weather, climate change, or each otherโ€”anything except the simple math.

The river never signed those agreements. And it is not interested in our love story with the past.

Lake Powell and Lake Mead were supposed to protect the system. Instead, we turned them into shock absorbers for delay.ย We wanted them to be savings accounts, when in reality we treated them like credit cardsโ€”use now, pay later.

Well, interest has accrued and the bill has arrived. Both reservoirs are in a treacherous situation.

The Colorado River fills Glen Canyon, forming Lake Powell, the nationโ€™s second-largest reservoir. The reservoir could drop to a new record low in 2026 if conditions remain dry in the Southwestern watershed. (Alexander Heilner/The Water Desk with aerial support from LightHawk)

Lake Powell was never meant to be drained so that hard decisions could be postponed downstream. It was designed to stabilize the system, to smooth out highs and lows; not to prop up demand that no longer matches supply. Year after year, Powell has been drawn down to protect uses elsewhereโ€”even as inflows decline and the margin for error disappears.

Lake Mead tells the same story from the other end. Despite conservation programs, pilot projects, and voluntary agreements, Mead keeps dropping. Not because we lack creativityโ€”but because we are still taking more water out of the system than the river is putting in.

Reservoirs donโ€™t lie.They are the silent accountants of what we actually do, not what we say weโ€™re doing.

Here in Colorado, when the river runs low, the impacts are immediate. We donโ€™t have a giant reservoir upstream to hide behind. Shortages here are hydrologic. They are real. Farmers fallow fields. Municipalities restrict use. Communities adaptโ€”not next year, not after another study or more modeling, but now. These impacts should be the indicator of the level of action that is needed across the entire Basin.

That lived experience mattersโ€”especially as we head into a post-2026 world.

Post-2026 is not just another chapter in the Law of the River, it is a reckoning.

The Interim Guidelines were written for a different riverโ€“-a river of the past. The drought contingency plans were emergency patchesโ€”not as a permanent fix but to buy time at a cost of more than a billion dollars until the next deal. We all know now those bandaids donโ€™t fix holes in reservoirs. And the idea that we can simplyย extendย these frameworks or merely modify them โ€”while Powell and Mead hover near critical elevationsโ€”is not leadership. Itโ€™s hope, not based on reality or experience, but avoidance.

In the post-2026 world, operations must be supply-based. Not demand-based. Not entitlement -justified. And not built on the hope that the next big year will save us. The harm will be irreversible because the Colorado River is NOT TO BIG TO FAIL.

Right now, the Basin States have a chance to prevent further irreversible damage and try to avoid bankruptcy. But that will only be possible if we all work together and see the stark reality of our present circumstances with clear eyes. We must build a framework that recognizes and adapts to the math problemโ€“supplies that regularly give us all less than our full rights and entitlements, that improves efficiencies for water intensive sectors, allows us flexibilities to help our neighbors when we can, and requires full transparency for measurement, monitoring, and accounting across the Colorado River System to build trust between us. Trust is difficult to rebuild when some donโ€™t acknowledge or adhere to the agreements already made.

That means releases from Lake Powell must reflect actual inflows, not political pressure.

It means protecting critical elevations is not optional.

And it means Lake Mead cannot continue to serve as a pressure valve for overuse.

We cannot manage scarcity with delay.

We cannot store our way out of imbalance with water that isnโ€™t there-that may never be there.

And we cannot negotiate with the simple arithmetic, no matter how many times we tell ourselves it will be different this time.

As sparks fly in the interstate negotiations, it is important to keep these realities in mind despite the rhetoric that attempts to distract.

Colorado is often told to โ€œcome to the table,โ€ as if weโ€™ve been absent. But weโ€™ve been here the entire timeโ€”bringing hydrology, realism, and a simple message:ย if reductions arenโ€™t real, reservoirs wonโ€™t recover. It is telling that what some refer to as an extreme negotiating position is based solely on the simple facts of hydrologyโ€”using more than the supply will bankruptthe entire system for everyone. How does the saying go? Doing the same thing over and over again and expecting a different result is the definition of insanity.

We are not asking for special treatment. We are not asking for a pass on doing our part to help save the system from collapse. We are asking for honesty. For reductions from both basins that are measurable, enforceable, and in proportion to useโ€”not in proportion to who can avoid the truth the longest.

Because if we donโ€™t choose how to live within the riverโ€™s limits, the river will choose for us. And it will not be gentle.

This is not a call for conflict.

Itโ€™s a call to face the reality of this unprecedented situation and come together to manage the River with wise and mature decision-making.

Lake Powell and Lake Mead are no longer warnings. They are verdicts. They are telling usโ€”clearly and without spinโ€”that the era of surplus, overuse, of clever deals is over.

The question facing all of us post-2026 is simple:

Do we align the rules with the river we actually haveโ€”or keep clinging to a past that no longer exists?

So as I head East I take you with me, because I know you all are doing the real work back on the home front. This year’s current hydrology demands it. I know Coloradans will be prepared, like they always have been. Fields will be fallowed, municipalities will be preparing to manage within their resources, deals will be made to protect fish and flows. Junior priority water users know that years like this one will call for collaboration and innovation, senior priority water users will work within the law and with those that are suffering, you will help each other pay the bill from Mother Nature because you know we all rise and fall together.

You all are here doing the real and hard work, and I will take that with me.Coloradans should be proud that we are choosing reality over fantasy, science over slogans, and responsibility over delay.

That is not weakness.

Thatโ€™s leadership.

January 29, 2026

This story is part of ongoing coverage of the Colorado River, produced by KUNC in Colorado and supported by the Walton Family Foundation. KUNC is solely responsible for its editorial coverage.

Governors in the Colorado River basin and their negotiators are meeting with Interior Secretary Doug Burgum in Washington on Friday to try and break a yearslong impasse among states over how to share the dwindling waterway.

On the eve of the high-stakes summit, negotiators from both the upper and lower river basins are not sounding confident they can reach an agreement before a fast-approaching Feb. 14 deadline.

โ€œIt depends on the day that you ask me,โ€ Coloradoโ€™s negotiator, Becky Mitchell, said Tuesday when asked by KUNC News if she thinks the states are heading toward a court battle. โ€œBut I will tell you the level of commitment that we have, both within Colorado and the upper basin, is strong to try to find some way to make a deal. Thereโ€™s some things that we can’t give on.โ€

Negotiators are currently working against the backdrop of record low-snowpack across much of the West and worsening forecasts for the Colorado River’s water supply. 

Mitchell said negotiators are continuing to talk at least twice each week.

But leaders from the upper and lower basin states say they still have sticking points.

They continue to differ on how water cuts should be handled and how releases from Lake Powell should be managed during dry years.

“Some in the lower basin wanted some sort of guaranteed supply, irrespective of hydrologic conditions,โ€ Mitchell said. โ€œAnd I think asking people to guarantee something that cannot be guaranteed is a recipe that cannot get to success.โ€

The lower basin states of California, Arizona and Nevada are proposing to cut 1.5 million acre feet of their water use. Theyโ€™re also asking for water restrictions to be mandatory and shared among all seven states. 

Negotiators from the different basins spoke at public events on Wednesday to set the stage for the summit in Washington.

โ€œItโ€™s tough to say I’m looking forward to it, because that would be a lie,โ€ Mitchell told a large crowd Wednesday at a water conference in Aurora.

Her speech was fiery at times.

โ€œOperations must be supply based, not demand based, not entitlement justified, and not built on a hope that the next big year will save us,โ€ she said. โ€œThat harm will be irreversible, because the Colorado River is not too big to fail.โ€

As Mitchell was addressing the water conference in a hotel ballroom, Californiaโ€™s water negotiator, J.B. Hamby, was talking to roughly 600 people on a webinar about his take on the state of negotiations.

He largely focused on his desire to still find a compromise among the seven states in the river basin.

โ€œIt’s better to be able to work something out across the negotiating table, to do something that makes sense and protects our users and people and agriculture in our state, and as a result of that, getting a seven-state agreement that protects those interests,” he said.

Hamby said the federal government is โ€œleaning inโ€ and becoming more involved in the negotiations by offering potential options.

Hamby called the feds’ ideas helpful.

โ€œContinued back and forth between the basins havenโ€™t really been moving the ball forward,โ€ he said. โ€œThe administrationsโ€ฆhave this important role in sometimes knocking heads together, sometimes encouraging consensus, and having diplomatic discussions between the states to be able to move conversations forward.โ€

He pointed to Herbert Hooverโ€™s role in 1922 as then Commerce Secretary to broker a deal among states in the river basin over how to share water. 

โ€œItโ€™s going to take everyone chipping in and making the necessary (water) reductions to balance the supply with the demand we have moving forward,โ€ Hamby said.

January 2026

As Colorado River supplies and demands reach razor-thin margins, new tools to provide adaptive capacity will play a critical role in sustaining communities across the West. We mustย reduce our consumption of water, while finding ways to cushion the impact. One of the most innovative tools for doing this, developed over the last two decades, is โ€œAssigned Waterโ€ – giving users the ability to store conserved water earmarked for their own future use.

Originally developed as โ€œIntentionally Created Surplusโ€ in the 2007 Colorado River Interim Guidelines, Assigned Water has been revised and expanded through U.S.-Mexico Treaty Minutes and as part of the 2019 Drought Contingency Plan. While conceptually simple and demonstrably valuable – a savings bank for conserved water – it is crucial to get the policy tools right as Colorado River management rules evolve.

For agencies granted access to the tool, Assigned Water provides important adaptive capacity to prepare for and manage shortfalls on a volatile river with shrinking supplies. But nearly two decades of operational experience also have exposed unintended consequences. With Assigned Water likely to play a critical role in basin management going forward – including its potential expansion to the Upper Colorado River Basin – it is important to review the strengths of the existing program, and essential lessons learned, to guide the development of river management policies after the current operating rules expire at the end of 2026.

HOW ASSIGNED WATER WORKS

Assigned Water allows some users to either conserve water that would have been used, import some categories of tributary water to the mainstem, or to fund system improvements to conserve water that would otherwise have been lost to inefficiencies. This water is then earmarked for the creating agenciesโ€™ use, sitting outside of the priority system through which the rest of the Colorado Riverโ€™s water is allocated. Agencies can pay users to take out their lawns, or fallow farm fields, banking the saved water for future use. By planning ahead, water agencies secure a reliability hedge against shortages as the river shrinks.

But at a time when overall water supplies are declining, Assigned Water creates a category of โ€œprivate water,โ€ available only to specific users, while remaining water allocated to all users under the existing priority system continues to shrink.

Assigned Water created a tool to overcome the โ€œuse it or lose itโ€ problem that left little incentive for water agencies to conserve. Its usefulness and subsequent expansion have led to the existence of 3.5 million acre feet now are stored in Lake Mead, representing the bulk of the available water currently in the reservoir.

UNINTENDED CONSEQUENCES

Delaying Shortage Actions

By keeping Lake Mead levels higher than they otherwise would have been, Assigned Water delayed formal shortage declarations in the Lower Colorado River Basin. While this was an intended benefit, it has had the practical effect of putting off water use reductions to the detriment of reservoir storage.

Subsidizing Evaporation

Although current rules apply some reductions to Assigned Water accounts, they often fail to fully account for actual evaporation. This results in a subsidy for Assigned Water holders at the expense of water available to everyone else.

Crowding Out

Assigned Water creates incentives for agencies to focus their conservation efforts primarily on programs that benefit their own users, potentially at the expense of the kind of broader efforts that will ultimately be needed to bring Colorado River Basin use into balance with physical supply. We must remember that Assigned Water does not permanently reduce the use of a quantity of water; instead it stores it for later, simply deferring that use to the future.

Inequitable Access

Assigned Water is currently available only to a select group of major Colorado River water agencies, depriving other users of the program’s benefits.

KEY RECOMMENDATIONS

Operational Neutrality

Assigned Water should not be included in the reservoir levels used to make shortage declaration and determine reservoir operations.

System Assessment

Agencies granted access to Assigned Water should pay a โ€œsystem assessmentโ€ for the privilege. This mechanism would credit their earmarked storage account for a portion of the conserved water while converting the remainder to โ€œSystem Water,โ€ helping to rebuild storage and meet broad Basin needs.

Evaporation Assessment

Accounting for evaporation should use the best available science, to avoid subsidizing Assigned Water accounts at the expense of the rest of the Basinโ€™s water users.

Expand Access

A wider range of users should be given the opportunity to participate in and benefit from Assigned Water tools.

ADDRESSING THE COLORADO RIVER BASINโ€™S TRAGEDY OF THE COMMONS

For more than a century of development, Colorado River governance has lived under a tension between individual communitiesโ€™ desires to use more water and the collective need to balance basin-scale supply and use for the benefit of the region as a whole. Incentives favoring individual communities at the expense of the collective good have brought us to the edge of the current crisis.

Going forward, Assigned Water can provide a crucial management tool, but the policies we use to implement it must find the balance between individual benefit and collective good.


GLOSSARY OF KEY TERMS

  • Priority Water:ย Water diverted within the U.S. generally under the prior appropriation system of water allocation.
  • Mexican Water:ย Water that flows past the international border into Mexico pursuant to the 1944 U.S.-Mexico treaty
  • Assigned Water: Water resulting from water use reduction programs that is stored in Colorado River Basin reservoirs earmarked for the specific use of the users who created it, outside the normal priority system. Assigned water functions as a sort of private water savings account for those agencies granted the privilege of using the tools.
  • System Water:ย System Water: The collective term for all water in the reservoirs, including Priority, Mexican, and Assigned Water.
  • Intentionally Created Surplus: The term used for the Assigned Water initially created under the 2007 Colorado River Interim Guidelines, which became the prototype for similar programs that followed.
  • System Conservation: Programs that fund reductions of water use to benefit the
  • Colorado River Basin as a whole by creating System Water for rebuilding reservoir storage or general use under the priority system rather than being allocated to the accounts of specific users.

APPENDIX OF ALL RECOMMENDATIONS

NEUTRALITY

  • In any newly developed operational guidelines for Lake Powell and Lake Mead, volumes of Assigned Water created after 2026 should be invisible for purposes of determining shortage conditions.
  • Other than for flood control releases, volumes of Assigned Water created after 2026 should be invisible for purposes of determining surplus in Lake Mead.
  • Volumes of Assigned Water in Lake Mead and Lake Powell created after 2026 should spill before all other water, a condition that also functions as a de-facto limit on total accumulation of Assigned Water.
  • In any newly developed operational guidelines for Lake Powell and Lake Mead, volumes of Assigned Water created after 2026 and held in Lake Mead or Lake Powell should be invisible for purposes of calculating annual releases from Lake Powell.

EVAPORATION

  • Reclamation should establish evaporation coefficients applicable to calculation of evaporation caused by storage of Assigned Water. These evaporation coefficients should be based on on-going monitoring and best available science and appropriately funded. Evaporation coefficients should be reassessed every five years, especially in light of a changing climate.
  • Future volumes of Assigned Water in any reservoir should be assessed a realistic and conservatively high annual evaporative loss based on these coefficients and on the amount of Assigned Water in storage.
  • Future deliveries of Assigned Water should be assessed transit losses where appropriate. Transit losses should also be estimated based on best available science, updated by monitoring and scientific studies, and revised every five years.
  • Future volumes of Assigned Water in any reservoir should proportionately share the evaporative (and transit) losses that occur due to Mexican Water delivery obligations (other than for Mexican Assigned Water, which should bear its own losses) and should be assessed a realistic and conservatively high annual evaporative loss based on these coefficients and due to Mexican Water delivery obligations. The evaporative assessment should reflect the proportionate share of Assigned Water and Priority Water in storage.
  • Evaporative losses should be assessed under all conditions, including shortage.

SHORTAGES AND DELIVERIES

  • Deliveries of Assigned Water should be restricted if necessary to protect critical dam infrastructure.
  • Alternative: The federal government should compel the sale of Assigned Water for immediate conversion to System Water during years in which reservoirs are at critically low levels.

PARTICIPATION

  • In years in whichย System Water storage in Lake Powell and Lake Mead is deemed to be inadequate, any Assigned Water developed or acquired by the federal government in those years should immediately be converted to System Water. Use for other purposes should be allowed only in conditions in which System Water storage is adequate.
  • Dedication of federally-controlled Assigned Water for purposes other than conversion to System Water should occur through a robust and transparent public process.
  • Because they are among those most exposed to involuntary shortage, CAWCD subcontractors that rely on deliveries of Colorado River water to surface water treatment plants should be allowed to create, own and acquire Assigned Water.
  • Entities without an entitlement to Colorado River water should not be allowed to own Assigned Water.
  • The Secretaryโ€™s approval should be required for all agreements for creation, transfer, or sale of Assigned Water.
  • Any Colorado River entitlement holder, with the concurrence of the Secretary, should be allowed to participate in transactions in any state to develop, own or use Assigned Water created from projects in the U.S. (So long as adequate protections are afforded Priority Water and there is agreement between the states regarding accounting for Assigned Water deliveries under the Compact).
  • To avoid profiteering, the Assigned Water held by any given Colorado River entitlement-holder should be proportional to its Colorado River entitlement. The annual accumulation and balance of Assigned Water for a single entity in any reservoir should be limited to some (relatively small) multiple of its annual entitlement to Colorado River water.
  • To ameliorate concerns about permanent water transfers between states, agreements to create Assigned Water from consumptive-use reductions in one state for delivery in another state should be structured such that there is reasonable means for entities within the state in which the reduction in consumptive-use derives to make use of that water within the state in the future. One means to do so would be to allow agreements to create Assigned Water from consumptive-use reductions in one state for delivery in another state only if the agreements expire after five years and do not include a provision for automatic renewal. Existing Assigned Water storage could continue beyond expiration.
  • To ameliorate controversies associated with the transfer of agricultural water for municipal use, agreements to create Assigned Water from consumptive-use reductions in agriculture should include a requirement that the funder of the Assigned Water pay a tax assessed per acre-foot paid to the county or counties from which the consumptive-use reductions derive. The tax could derive from the value of the agricultural economy. Waivers could apply if the Assigned Water creation program creates a net increase in economic value in an agricultural area (e.g., crop switching or crop insurance).

ASSIGNED WATER CREATED THROUGH SYSTEM EFFICIENCIES

  • The federal government should fund efficiency projects for creation of System Water up until the amount of water that results from such projects sufficiently ameliorates the impacts of the annual, national obligation to Mexico to Priority Water users.
    • Thereafter, the creation of Assigned Water via efficiency projects in the U.S. should only be allowed if a) System Water storage in Lake Powell and Lake Mead is deemed to be adequate or b) the efficiency project benefits System Water over Assigned Water on a ratio of 90/10 over the ensuing five years.
  • To the extent participation is offered, participation in efficiency projects in the U.S. in exchange for Assigned Water should be awarded based on an allocation method determined through an open and transparent process (e.g. highest bidder) and should be subject to any limitations on participation,ย total Assigned Water annual accumulation and balance for that entity.
  • The federal government should hold the right of first refusal to purchase any Mexican Assigned Water up for sale and to fully fund any conservation projects in Mexico that can become Assigned Water during years in which System Water stores are deemed to be inadequate for the sole purpose of converting it to System Water.
  • Mexican treaty obligations increase the risk of shortage in the Lower Division and increase the risk of a Compact call. Those in the Lower Division with lowest priority contracts and subcontracts and those in the Upper Division most at risk of curtailment due to a Compact call should be given the second right of refusal up to an amount that equals projected involuntary cuts to Priority Water for each entity over the next two years.
  • Thereafter, purchase of Mexican Assigned Water should be awarded to domestic entity with the highest bid and should be subject to any limitations on participation, total Assigned Water annual accumulation and balance for that entity.

MEASUREMENT AND BASELINES

  • An audit independent of Reclamation should be conducted on the existing Assigned Water program in the Lower Division and Mexico. The goals of the audit should be:
    • to examine claimed savings for accuracy,
    • to assemble a list of lessons learned on measurement and accounting from twenty years of program administration and
    • to assemble a list of qualifying activities for reduction of consumptive use, alongside recommended terms and conditions, that can form the foundation of future agreements.
  • The audit should be made available to the public with and opportunity to review and comment.
  • Assigned Water in any reservoir should only be allowed under a program that accurately measures Assigned Water creation, shepherding, storage and deliveries.
  • Owners of Assigned Water should be assessed an annual fee to fund robust measurement and enforcement programs.
  • Assigned Water created through water savings should derive from a baseline of historic consumptive use, not entitlement or filed water right claims.

FORBEARANCE/SHEPHERDING

  • Forbearance/shepherding should be based on qualifying activities, not participants. In other words, withholding of forbearance/shepherding should not be a veto used to exclude participants that would otherwise qualify for development of Assigned Water.
  • The means of creating Assigned Water that meet the threshold for agreements to forbear/shepherd should be decided ahead of time. Allowing additional qualifying activities down the road increases flexibility but also potentially undermines trust in Assigned Water programs between participants and more importantly among non-participants who rely solely on the prior appropriation system.

TRANSPARENCY

  • Reclamation should compile a centralized, searchable, easily accessible library of all agreements and documents associated with Assigned Water programs.
  • Reclamation should develop a new Assigned Water annual report that clearly shows ownership of the several different types of Assigned Water, the status of funding agreements and the flow of dollars, transactions involving Assigned Water, Assigned Water creation by creation category, method and partner, relevant shepherding arrangements, assessments, evaporative losses, deliveries and ending balances and other relevant details.
  • Graphs and charts of reservoir elevations should clearly delineate Assigned Water by ownership and method of creation.

PROGRAM LENGTH

  • The ability to create or purchase Assigned Water under a given Assigned Water program should expire 20 years after program initiation, a duration long enough for bond financing of capital projects. The ability to store Assigned Water should expire no more than 5 years after expiration of the program under which it was created.

LOANS AND CONVERSIONS

  • Loans against Assigned Water balances should not be allowed where default diminishes the amount of System Water in storage.
  • Conversion of existing Assigned Water into another form of Assigned Water governed by different rules should only be allowed after a robust and transparent public process.
  • Loans between Assigned Water owners for Assigned Water should be allowed in future programs.
  • With proper guardrails, loans from Assigned Water owners to Priority Water users should be allowed, including across state lines.
  • With proper guardrails, loans and/or conversions from Assigned Water to the Priority Water pool should be mandatory when Priority Water stores are deemed to be seriously inadequate.

ADDRESSING THE TRAGEDY OF THE COMMONS

  • Future creation of Assigned Water should be assessed a percentage deduction that becomes System Water at the time of creation to help rebuild System Water in reservoirs.
    • The assessment should be determined based on a sliding scale; a 30% assessment should apply in water years in which System Water stores are deemed to be inadequate. The assessment should then decrease incrementally to 10% as total storage increases.
  • Alternative: Colorado River entitlement holders must agree to take shortages above and beyond shortage levels described in the 2007 Guidelines before being allowed to create Assigned Water.
    • The amount of shortage should equal 30% of the proposed deposit in years in which System Water stores are deemed to be inadequate. The shortage should then decrease incrementally to 10% as total storage increases.
  • During years in which System Water stores are deemed to be inadequate the federal government should hold the right of first refusal to purchase any Assigned Water offered up by willing sellers for the sole purpose of converting it to System Water.

ASSIGNED WATER OPPORTUNITIES IN THE UPPER DIVISION

  • Where possible while still maintaining neutrality to Priority Water, and assuming agreement between the states on how to account for Assigned Water deliveries between the Divisions under the Compact, the amount of Assigned Water stored in different reservoirs should be adjusted to optimize for hydropower, environmental and recreational benefits.
  • Assigned Water created in the Upper Division must be properly shepherded into the relevant downstream reservoir and assessed appropriate transit losses.

All alternatives harmful to #Arizona: The Central Arizona Projectโ€™s response to the Draft Environmental Impact Statement for post-2026 #ColoradoRiver operations — DeEtte Person #COriver #aridification

January 26, 2026

Reclamation has released a Draft Environmental Impact Statement (DEIS), a required step in the process to develop new operating guidelines for Colorado River operations by the end of the year when the current operating guidelines expire. It comes amid two-plus years of ongoing meetings and negotiations led by Reclamation working with the seven Colorado River Basin states, the Colorado River Basin tribes and other stakeholders.

The DEIS lays out five alternatives for how the Colorado River might be managed after 2026. These include one โ€œno actionโ€ alternative required by law, three alternatives that would require agreements among the basin states, and one โ€œno dealโ€ alternative which may be imposed if there is no agreement among the states.

The DEIS places all the risk of a dwindling Colorado River on the Lower Basin, and all the alternatives proposed are harmful to Arizona.

The โ€œno dealโ€ alternative in particular piles virtually all the mandated cuts on the State of Arizona and Central Arizona Project. The DEIS ignores the obligations of the Upper Basin states to deliver water under the Colorado River Compact and the federal government to release water from the Colorado River Storage Project dams.

The โ€œno dealโ€ alternative would result in a crushing blow to Central Arizonaโ€™s water supply, including tribal water supplies. Millions of Arizona residents would be negatively affected โ€“ including those in the fifth largest city in the United States, as would several of the nationโ€™s key industries, including manufacturing, microchips and national defense.

Our economy is integrated regionally and nationally, which means if Arizona is suffering, neighboring businesses and our national defense are too.

In contrast, the โ€œno dealโ€ alternative imposes no federal cuts to the Upper Basin and allows the Upper Basin to increase water use in the future.

Implementation of any of the DEIS alternatives would likely force Arizona to seek legal options. [ed. emphasis mine]

The basin states and the Bureau of Reclamation can do better than any of these alternatives with a negotiated agreement. As history has shown, the Colorado River has worked best when all basin states agree on how it is managed.

We remain committed to working with the basin states and Reclamation so long as the path is toward recognizing the shared risks and responsibilities for the river and fairly sharing reductions to protect vital infrastructure that benefits the entire Colorado River Basin.

Hereโ€™s what CAWCDโ€™s Board members have to say about the DEIS:

โ€œEach alternative put forward places the risk of a dwindling Colorado River on the Lower Basin โ€“ none of them are good for Arizona and certainly not for Central Arizona Project. In the Lower Basin, weโ€™ve demonstrated that we can accept that the River has less water now and likely in the future. But we cannot bear the shortage alone. The Upper Basin shows no willingness to conserve and in fact demands more water, yet these alternatives do nothing to deny their greed. Thatโ€™s not acceptable to CAP whose millions of water users and billions in industrial investments will bear the brunt of these devastating alternatives.โ€ย  โ€“ Terry Goddard, CAWCD Board President

โ€œThe alternatives laid out for post-2026 Colorado River operations are potentially disastrous for millions of Arizonans โ€“ including the residents of the fifth largest city in the United States. Further, these alternatives all negatively impact several of the nationโ€™s key industries, including manufacturing, microchips and national defense. This means harm not just to Arizona, but to the entire country.โ€ย  โ€“ Alexandra Arboleda, CAWCD Board Vice President

โ€œArizonans have been smart water stewards, conserving water for decades in our desert environment. Whatโ€™s more, weโ€™ve worked with our Lower Basin partners to protect Lake Mead, by voluntarily conserving water beyond the mandatory reductions Arizona has taken for the past several years. Weโ€™ve done our part and itโ€™s so disappointing to see alternatives that make Arizona bear the burden for all Colorado River users.โ€ย ย  โ€“ Karen Cesare, CAWCD Board Secretary

โ€œPinal County has already shouldered the brunt of the Colorado River reductions Arizona has been taking for the past several years. And this has had a monumental negative impact on our agricultural community. Weโ€™ve already felt a great deal of pain and these alternatives would be rubbing salt in the wound and would continue to devastate Arizona.โ€ย  โ€“ Stephen Miller, CAWCD Board Member, Pinal County

โ€œCAP delivers more tribal water than any other entity in the United States. The alternatives proposed for post-2026 Colorado River operations would have a damaging effect on those deliveries, which are part of settlement agreements with the federal government. The negative effects of these alternatives impact all of CAPโ€™s water users โ€“ cities, industries and tribes.โ€ย  โ€“ Justin Manuel, CAWCD Board Member, Pima County and member of Tohono Oโ€™Odham Nation

As deal deadline approaches, #ColoradoRiver stewards debate a broad range of options — Scott Franz (KUNC.org) #COriver #aridification

The Colorado River flows through Grand County, Colo. on Oct. 23, 2023. Negotiators from seven states remain at an impasse over how to share and conserve the river’s water despite four days of recent meetings together in Utah.

Click the link to read the article on the KUNC website (Scott Franz):

January 25, 2026

This story is part of ongoing coverage of the Colorado River, produced by KUNC in Colorado and supported by the Walton Family Foundation. KUNC is solely responsible for its editorial coverage.

Itโ€™s crunch time for negotiators from seven western states trying to strike a deal before Feb. 14 on how to share the dwindling Colorado River.

But four days of talks in a Salt Lake City conference room earlier this month did not appear to have sparked a breakthrough.

โ€œWe got tired of each other,โ€ Utahโ€™s negotiator, Gene Shawcroft, said Tuesday at a public board meeting, days after the meeting ended. โ€œAnd two of the days, we made some progress, but one day we went backwards almost as much progress as we made in two and a half days.โ€

The states in the lower and upper basins remain at an impasse over how cuts to water use should be handled during times of drought.

In another sign that talks remain stalled, Interior Secretary Doug Burgum reportedly invited governors from the seven states in the river basin to attend a meeting in Washington on Jan. 30. 

A spokesperson for Colorado Gov. Jared Polis confirmed the meeting invitation to KUNC and said in a statement that Polis โ€œhopes to attend this meeting if it works for the other Governors.โ€

Meanwhile, the Interior Department recently released a playbook of options for how to manage the river in the future.

John Berggren, a water policy expert at Western Resource Advocates, said many of the scenarios on the table can only be taken if all the states in the basin agree to them.

โ€œThe fact that the states don’t have a seven state agreement right now means that we can’t consider some of these really good, new, innovative tools that are in some of the alternatives,โ€ he said Tuesday. And so that’s pretty frustrating.”

What could management of the vital waterway look like after the current rules expire in August?

Berggren, who got his Ph.D. at the University of Colorado focusing on sustainable water management in the Colorado River Basin, helped KUNCโ€™s water desk summarize the five options on the table from the feds.

He said an eventual deal might incorporate pieces from several of the alternatives.

Basic coordination

This is the only path the feds say they currently have the legal power to take if the seven states fail to reach an agreement.

Berggren said this option would likely โ€˜normalizeโ€™ 1.48 million acre feet of water shortages each year in the lower basin states.

โ€œAnd this would just basically say every year, thatโ€™s a given,โ€ Berggren said.

It is mostly filled with mountain snowmelt from Utah, Colorado, Wyoming and New Mexico. Photo credit: Alex Hager/KUNC

Upper basin states, including Colorado, would not be forced to contribute more water in dry years.

Berggren said this option โ€œdoes not do enough.โ€

โ€œThereโ€™s many years where the system crashes,โ€ he said.

A crash means Lake Powell and Lake Mead reach deadpool, a scenario where theyโ€™re so critically low that hydroelectricity stops and water stops flowing through their dams.

Millions of water users in the west could see impacts.

Enhanced coordination

Berggren calls this plan โ€˜a little more innovative.โ€™

Highlights include the power to use conservation pools that encourage and incentivize states and water users to find ways to save water.

That could mean the feds paying states to conserve water. Lower basin states could also put water they save in Lake Mead to stay there until they need it.

โ€œItโ€™s water security, because if we can save water today, weโ€™ll put it into storage and we can withdraw it later when we need it,โ€ Berggren said.

This option also includes contributions from the upper basin states each year that would gradually increase over time.

The Interior Department writes this option โ€œseeks to protect critical infrastructure while benefitting key resources (such as environmental, hydropower, and recreation) through an approach to distributing storage between Lake Powell and Lake Mead that enhances the reservoirsโ€™ abilities to support the Basin.โ€

No action

This plan might sound like the path with the least impact, but thatโ€™s far from the case.

This path would revert the operating procedures at Powell and Mead to what they were almost 20 years ago.

โ€œIt basically says Reclamation will shoot to release 8.23 million acre feet of water from Powell, and thatโ€™s kind of it,โ€ Berggren said. โ€œNot a lot of authority for lower basin shortages, not a lot of authority to modify your reservoir operations to try and prevent the worst from happening. No action very clearly crashes the system quickly, and no one wants it.โ€

According to the Interior Department, โ€œthere would be no new mechanisms to proactively conserve and store water in Lake Powell or Lake Mead.โ€

This option was legally required to be included in the feds report on operating scenarios.

Maximum flexibility 

This proposal was developed by a group of seven conservation groups.

Interior said this alternative is โ€œdesigned to help stabilize system storage, incentive proactive water conservation, and extend the benefits of conservation and operational flexibility to a wide range of resources.โ€

Itโ€™s also designed to give dam operators more flexibility to respond to the impacts of climate change.

As water levels in Lake Powell keep dropping, some say they could fall too low to pass through Glen Canyon Dam at sufficient levels. Ted Wood/The Water Desk

Berggren said this option allows water users to conserve water and store it in reservoirs.

It would also change the way water releases are handled.

A โ€œclimate response indicatorโ€ would be introduced to help decide how much water should be released from Lake Powell.

โ€œIf the last three years have been really dry or exceptionally dry, then you adjust your Lake Powell releases,โ€ he said.

Berggren and his environmental group, Western Resource Advocates, had a hand in developing this alternative along with the six other organizations.

All seven of the organizations that crafted the river management proposal have received funding from the Walton Family Foundation, which also supports KUNCโ€™s Colorado River coverage.

Supply driven alternative

โ€œAll this does is say that what you release from Lake Powell down to Lake Mead is based on some percentage of the preceding three years,โ€ Berggren said. โ€œYou look at the past three years, and you take some percentage of that, and that’s what you release from Glen Canyon Dam, and that’s basically it.โ€

He said the plan, which incorporates ideas from the states themselves, was nicknamed โ€œthe amicable divorce of the basins.โ€

โ€œBecause it was basically the upper basin will do its thing with Lake Powell and its upper basin reservoirs,โ€ he said. โ€œAnd then whatever gets released, lower basin deals with that, deals with Lake Mead, deals with lower basin shortages.โ€

Shortages in the lower basin could be up to 2.1 million acre feet a year in this scenario, according to the Interior Department.

Public comment is being accepted on all five alternatives through early March.

Driving a system to crisis — Andy Mueller (#Colorado River District) #ColoradoRiver #COriver #aridification

From email from the Colorado River Water Conservation District (Andy Mueller):

January 17. 2026

The Colorado River system is on the brink of collapse, drained by decades of overuse in the lower basin states and accelerated by the impacts of climate change. While this is not the first time that we have stared down a crisis at Lake Powell, in the past, we have gotten lucky, saved by big snows and cold winters.

This year, however, it does not appear that Mother Nature is going to bail us out.

On the Western Slope, we spent our holidays staring at snowless, brown hillsides and dry, rocky riverbeds as water year 2026 began setting records โ€” all in the wrong direction. At the Colorado River District, our job is to protect the water security of the Western Slope, regardless of the condition of the snowpack. We canโ€™t make it snow, but we can hold decision-makers accountable for their choices, and as we near the deadline of the post-2026 river operation guideline negotiations, we can demand that they do not continue to make the same mistakes which have driven us to this crisis.

In recent months, as pressure and public scrutiny have grown around the negotiations between the seven Colorado River Basin states, it has become clear that the Lower Basin states of Arizona, California, and Nevada are looking for a scapegoat. They have begun loudly accusing the Upper Basin states of Colorado, Utah, Wyoming, and New Mexico of being inflexible and unwilling to compromise on a solution to balance the system. They believe that their political might and economic clout entitles them to continue to use more than their share and absolves them of responsibility for their part in the collapse of the system.

But that is not reality.

Over 100 years ago, the Colorado River Compact was designed with exactly this moment in mind. It was created to allow Upper and Lower Basin states to develop their water separately, to meet the needs of their unique communities on their own timeline, and to steward their resources responsibly.

In eight pages, the Compact makes it clear that the communities of suburban Phoenix are not more important than those of western Colorado.

Think about it like this: in 1922, the Upper and the Lower Basin each bought a brand-new truck. Both came with contracts and manuals explaining proper use and maintenance, limits and legal obligations.

For years, their engines hummed.

During this time, the Lower Basin chose to modify their purchase contract to upgrade. They signed on the dotted line to accept the feds as their water master when they wanted to build Hoover Dam, and Arizona agreed to take junior water rights on the system to develop the Central Arizona Project.

But as things heated up in the early 2000s, the warning lights began to come on.

The Upper Basin quickly adapted to changing conditions, slowing down, or driving carefully around uncertain terrain. Without large reservoirs upstream and guaranteed water deliveries, water managers and agricultural producers in these states had to make tough decisions every month based on how much water was actually in the river.

The Lower Basin, however, chose to ignore the warning lights on their dashboard. Despite being told by multiple mechanics that they couldnโ€™t continue to drive full speed anymore, they kept their foot on the gas.

Regardless of worsening hydrology, they overused their allotment by as much as 2.5 million acre-feet per year by not accounting for evaporative and transit loss or their full tributary use. In addition to this, Arizona hoarded over 300,000 acre-feet annually of Colorado River water by dumping it into the ground.

Left unaddressed, the problems compounded. Now their truck is seizing up, and the driver is trying to explain to everyone onboard why their broken vehicle is someone elseโ€™s fault.

In western Colorado, we have never had the luxury of looking away from the wear and tear caused by prolonged drought. Every year, we adjust our use to meet our obligations downstream and protect the health of our communities.

The 1922 Compact is not being renegotiated, but the interim rules governing water apportionment on the river are.

Any new agreements must recognize the hydrologic reality that water is a finite and shrinking resource and be consistent with our existing legal framework. New agreements must end the fiction that growth can continue without considering hydrology and reject any deal that forces western Colorado to subsidize decades of overuse elsewhere.

January 20, 2026

After last weekโ€™s somewhat wonky dispatch on the Colorado River, a couple of readers asked about some of the terminology used. That, along with the fact that the deadline for an agreement on how to operate the riverโ€™s plumbing is fast approaching, prompted me to put together a bit of a glossary/primer on the Colorado River to give a little more context to related news, which is likely to come fast and furious over the next several weeks. 

If I miss anything, or if you have other questions, please let me know and Iโ€™ll try to answer them soon. Also, Iโ€™ll be doing a host of data-driven, Colorado River-related dispatches in coming weeks to go over some of last yearโ€™s statistics on water consumption, water pricing, alfalfa production and exports, and so forth.

Colorado River Basin: A 250,000 square-mile watershed that includes southwestern Wyoming, western Colorado, southern and eastern Utah, southern Nevada, western New Mexico, Arizona, and eastern California. For administrative purposes, it has been split into the Lower Basin (CA, AZ, NV) and the Upper Basin (CO, WY, UT, NM), with the dividing line at Lees Ferry.

Law of the River: This isnโ€™t an actual law, but rather a collection of agreements, compacts, treaties, laws, and Supreme Court decisions that serve as a framework for governing the Colorado River.

Doctrine of Prior Appropriation, aka First In Time, First in Right: This is the basis for most Western water law, which says that the first entity to put a set amount of water on a stream to beneficial use at a specific place has the highest or most senior priority of water rights. If a senior rights holder is not receiving their full appropriation due to drought or overuse, they can make a โ€œcallโ€ on the river, forcing upstream, junior rights holders to stop diverting water from the stream or its tributaries.

Acre-foot (AF): Amount of water that would cover one acre one foot deep. 1 acre-foot = 325,851 gallons. MAF = million acre-feet.

Consumptive Use:ย The amount of water diverted from a stream minus the amount returned to it. For example, last year Nevada pulled about 443,000 acre-feet of water from the Colorado River, mostly via pumping plants in Lake Mead. But it returned about 244,000 acre-feet of treated wastewater to the reservoir via Las Vegas Wash, leaving it with a total consumptive use of about 198,000 acre-feet for the year. Evaporation and transpiration (or uptake by and evaporation from plants) are considered consumptive uses. Agriculture is the largest consumptive user in both the Upper and Lower basins.

Colorado River Compact: In 1922, representatives from the seven Colorado River states entered into a compact aimed at ending interstate conflict and litigation to clear the way for developing dams and diversions on the river. The compact gives each basin exclusive beneficial consumptive use of 7.5 million acre-feet of water per year, but also mandates that the Upper Basin โ€œnot cause the flow of the river at Lee Ferry to be depleted below an aggregate of 75 million acre-feetโ€ for any 10-year period. A 1944 treaty reserved an additional 1.5 million acre-feet to Mexico, which would be covered by surplus or borne equally by the two basins.

I like to run this one again from time to time, just to remind folks how much the population of the West has grown over the last century. This is what the signers of the Colorado River Compact were dealing with as far as water users go โ€” compared to some 40 million users now. Source: USGS.
  • The Upper Basin divided its 7.5 MAF by percentage:ย 51.75%ย to Colorado;ย 11.25%to New Mexico;ย 23%ย to Utah;ย 14%ย to Wyoming (plus an additionalย 50,000 acre-feetย for the portion of Arizona in the Upper Basin).
  • The Lower Basin allottedย 4.4 MAFย to California;ย 2.8 MAFย to Arizona;ย .3 MAFย to Nevada.
  • 20 million acre-feet: Presumed total annual natural flow of the river upon which the compact was based and which was considered โ€œmore than sufficient to water all lands now being irrigated and all lands which can be economically developed for forty years to come.โ€
  • 17.3 million acre-feet: The actual annual flow recorded by the he U.S. Geological Survey during the nine years leading up to the compactโ€™s ratification, with yearly flows ranging from 9.9 million acre-feet to 26.1 million acre-feet. That was during an unusually wet period.
  • 14.3 million acre-feet: Median annual natural flows at Lees Ferry from 1907 to 2025.
  • 8.5 million acre-feet: Estimated natural flow at Lees Ferry in 2025.
  • 2 million to 4 million acre-feet: Estimated amount of consumptive use that must be reduced to bring the Colorado River supply and demand into balance.

Natural Flow at Lees Ferry: This is a calculated estimate of the amount of water that would flow past Lees Ferry if there were no upstream dams, diversions, or human consumptive use. This estimate would guide the supply driven option for dividing up the river. The USBR describes the method for determining it as such:

  • Provisional Natural Flow at Lees Ferry = observed annual flow at Lees Ferry + average Upper Basin consumptive use for the last 5 published years +/- net change in mainstream storage +/- net change in off-mainstem storage +/- net change bank storage + mainstem reservoir evaporation.
The estimated โ€œnatural flowโ€ at Lee Ferry. Some of the alternatives would base Lake Powell releases on recent average natural flows at Lee Ferry. If the recent past is an indicator of whatโ€™s to come, we could expect a relatively minuscule amount of water running through the Grand Canyon to the Lower Basin states. Source: Bureau of Reclamation.

Winters v. the United States:ย 1908 Supreme Court ruling establishing that when the federal government โ€œreservedโ€ land for a tribal nation, it also reserved rights to water. And the appropriation date for those water rights would be the date the reservation was established, whether or not the tribe put the water to โ€œbeneficial useโ€ at that time.ย Wintersย did not quantify the amount of water tribes were entitled to, except that it should be โ€œsufficient โ€ฆ for irrigation purposes.โ€

  • By rights, this would give the 30 tribal nations within the watershed the most senior rights to most if not all of the water in the Colorado River. Five lower Colorado River tribes currently have quantified and settled rights to about 900,000 acre-feet, while Upper Basin tribes have settled and quantified about 1.1 million acre-feet. But other tribes have yet to settle or quantify their rights, so they remain in a sort of limbo.
  • In many cases, the tribal nations lack the infrastructure for putting their water rights to use, meaning they end up relying on federal infrastructure โ€” and on the respective appropriation dates for the infrastructure. An example: The Ute Mountain Ute tribe has 1868 water rights on the Dolores River in southwestern Colorado. But they actually receive their water via the Dolores Project, which only has 1968 rights โ€” which are junior to most of the white farmers on the river. That means during very low water years, the tribe can lose most of its water.

Eugene C. LaRue:ย One of the early 20th centuryโ€™s foremost authorities on the Colorado River, who warned the Colorado Compact signatories that their negotiations were based on overestimates of the riverโ€™s supply. In 1916, he wrote: โ€œEvidently, the flow of the Colorado River and its tributaries is not sufficient to irrigate all the irrigable lands lying within the basin.โ€ LaRue also warned against building Hoover Dam because evaporation would further deplete water supplies and suggested banning trans-basin diversions, or exporting water from the Colorado River watershed to other parts of the seven basin states. The signatories heard LaRue but clearly didnโ€™t heed his warning, even though he repeated it many times prior to the compactโ€™s signing. (He eventually resigned in protest.)

Minimum Power Pool: Surface elevation of Lake Powell or Lake Mead below which hydroelectric production is no longer possible because it is lower than the damโ€™s penstocks. This is especially critical at Lake Powell because if water canโ€™t be released through the penstocks and turbines, it must go through lower river outlets, which are not equipped for long-term releases and could be damaged by constant use. Also, the electricity from the dam is critical to Southwestern power grids, and sales of it raise revenue for endangered native fish recovery programs.

Deadpool: Surface elevation of Lake Powell or Lake Mead below which no water can be released from the dam. So in Lake Powell, this means the water would drop below the river outlets, which could happen if the reservoir is drawn down to the river outlet level, and then reservoir seepage and evaporation exceeds inflows (which could happen late in a hot, dry summer).

Run of the River: This is the term for when releases from a dam are equal to reservoir inflows minus evaporation and seepage at any given time. In other words, if inflows were 20,000 cfs, releases would be slightly lower, and the dam wouldnโ€™t hold any water back (or release any storage). Glen Canyon dam operators could use this method to keep Lake Powell from dropping below minimum power pool.

Transbasin Diversion: Moving water from one watershed to another, within the same state, e.g. from the Colorado Riverโ€™s headwaters to the stateโ€™s populous Front Range, or from the Navajo River (a tributary of the San Juan, which is a tributary of the Colorado) to the Chama River (a tributary of the Rio Grande).

Central Arizona Project: The 366-mile canal and pumping system that delivers Colorado River water to the Phoenix and Tucson areas. The projectโ€™s water rights have a 1968 appropriation date, making them junior to California users such as the Imperial Irrigation District. That has meant that Arizona must reduce consumption prior to California. 

Imperial Irrigation District: A major agricultural area in southern California and the Colorado Riverโ€™s largest single water user.

January 20, 2026

There continues to be no new information from the ongoing negotiations among the protagonists for the seven states trying to work out a new two-basin management plan for the Colorado River. The Bureau of Reclamation, however, is pressing ahead; it recently went public with its โ€˜Draft Environmental Impact Statementโ€™ (DEIS) for โ€˜Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead.โ€™

The five alternative โ€˜operational guidelines and strategiesโ€™ analyzed in this DEIS were announced back in the fall of 2024; the Bureau has spent the past year-plus examining their environmental impacts. Iโ€™m not going to go into their analyses right now; Iโ€™m still working on skimming, skipping, sprinting and plowing my way through enough of the 1600 pages or so of the report to feel reasonably informed on its contents.

But I will note that the first action analyzed (skipping past the mandatory โ€˜No Actionโ€™ alternative) is for the Bureau to go ahead and run the river system as it sees fit, without input from the seven states/two basins โ€“ not something they want to do, but would have to do since the system will not wait while the states stare at their chessboard stalemate. That action would of course precipitate lawsuits from some of the states since the Bureau would have to go ahead with some of the things that are part of non-debate behind the stalemate.

Anyone wishing to submit themselves to the torture of an EIS can find the home page and Table of Contents for the report by clicking here.

And in the meantime, Iโ€™ll go off again on what I hope might be at least a more interesting tangent, and maybe more creative โ€“ fully believing that the only way out of our ever-unfolding river mismanagement is some centrifugal push to get beyond the tight centripetal pull of the Colorado River Compact and its two-basin expedient that has become gospel.

Two posts ago here, I acknowledged a need to explain why I titled all these posts โ€˜Romancing the Riverโ€™ โ€“ โ€˜romanceโ€™ being a degraded term these days for many people, most commonly referring to formulaic fiction about chaotic and improbable couple-love relationships. This is a sad degradation of a word that, in more imaginative times, referred to a much larger quality or feeling of adventure, mystery, something beyond or larger than everyday life โ€“ โ€˜your mission should you choose to accept it,โ€™ as it was expressed in Mission Impossible and The Hobbit.

โ€˜Romanceโ€™ has been used to describe our relationship with the Colorado River for more than a century. C. J. Blanchard, a spokesperson for the Bureau of Reclamation in 1918, spoke of the โ€˜romance of reclamation,โ€™ observing that โ€˜a vein of romance runs through every form of human endeavor.โ€™ The first book compiling the history of the Euro-American exploration of the Colorado River was titled The Romance of the Colorado River. Written by Frederick Dellenbaugh, something of an explorer himself, he first encountered the Colorado River in the company of one of the riverโ€™s greatest romantics, John Wesley Powell, on Powellโ€™s second adventure into the canyon region of the river.

Now wait a minute, you may say: John Wesley Powell a romantic? Everyone knows he was a scientist! Well, yes, that too. A romantic scientist. Let me try to explain.

Science is a discipline, perhaps summarized in the caution: Look before you leap. Science is the discipline of looking, studying, analyzing for causes in some studies, for effects in others, basically trying to map out what is demonstrably going on in the system or structure being studied. But most scientists will acknowledge being also moved by feelings, convictions, beliefs that lie outside of or beyond the linear relationships of cause and effect explorations. The extreme example might be scientists who believe in a god or gods that oversaw the creation they are studying. More subtly, the very desire to pursue a life in science reflects a belief beyond evidence that the work is important as well as interesting. This is the โ€˜romanceโ€™ underlying science and those who pursue it.

The same year Dellenbaugh published his Romance, 1903, another southwestern writer, Mary Hunter Austin, came out with her Land of Little Rain, a poetic collection of her explorations in the deserts of the lower Colorado River region. In that book she offered what might be a cautionary note about โ€˜romancing the river.โ€™ In an observation about a small central Arizona tributary of the Colorado River, โ€˜the fabled Hassayampa,โ€™ she reports an unattributed legend: โ€˜If any drink [of its waters], they can no more see fact as naked fact, but all radiant with the color of romance.โ€™

That could be construed into a kind of spectrum, the โ€˜naked factsโ€™ of any situation at one end, the โ€˜radiant colors of romanceโ€™ dressing up the naked facts at the other end. The discipline of science is to stay as close to the โ€˜naked factsโ€™ as possible. But is it a bad thing to allow feelings or beliefs to dress up the naked facts with the radiant color of romance?

Hold that question for a bit, and back to Major John Wesley Powell. Powell was a scientist by nature โ€“ meaning born a curious fellow who collected information about things that made him curious. He studied science in a couple of colleges, but never completed a degree โ€“ partially, probably, because college science was a little too tame. One of his early โ€˜field tripsโ€™ was a solo trip the length of the Mississippi River in a rowboat. Another was a four-month walk across the โ€˜Old Northwest Territoryโ€™ state of Wisconsin. Both of those trips pretty unquestionably fall more into the category of โ€˜romantic adventuresโ€™ than โ€˜scientific expeditions.โ€™

As a son of an itinerant farmer/preacher immigrant, growing up on farms in rural New York, Ohio and Illinois, he also shared, to some extent, the romantic Jeffersonian vision of โ€˜another America,โ€™ a nation of small decentralized and mostly locally-sufficient communities of farm families โ€“ now just a nostalgic fantasy-vision of nation building that still haunts the imperial urban-industrial mass society that America has become. But trips to the west had convinced Powell that the mostly arid lands of the West were largely unsuitable for the spread of that agrarian vision, without the development of an appropriate system for settlement and land management specifically for the arid lands.

He had ideas about that, things to say, but he was basically just a high-school teacher who spent his summers adventuring west; how could he get a hearing for his concerns and ideas? He needed some way to gain public attention. So he turned his destiny over to his romantic adventurer side: he would do a scientific investigation into one of the remaining blank spots on the continental map, the region beginning where the rivers draining the west slopes of the Southern Rockies disappeared into a maze of canyons, and ending where a river emerged from the canyons โ€“ a river thick with silt and sand, indicating a pretty rough passage through canyons still in the creation stage.

Wallace Stegner, in his great book about Powell and the development of the arid lands, Beyond the Hundredth Meridian, credited Powellโ€™s scientific grounding with getting him through his 1869 expedition into the canyons: โ€˜Though some river rats will disagree with me, I have been able to conclude only that Powellโ€™s party in 1869 survived by the exercise of observation, caution, intelligence, skill, planning โ€“ in a word, Science.โ€™

Iโ€™m one of those who disagree with Stegner on that point. The advance planning for the trip sank in the first set of Green River rapids, with the wreckage of one of the boats containing a large portion of both their food supply and scientific instruments. They gradually acquired some skill at negotiating rapids (and knowing when to portage instead), but they started with no skill and paid the price. Observation was limited to the stretch of river before the next bend. Dellenbaugh asked Powell, on the second trip in 1871-72, what he would have done had he come to a Niagara-scale waterfall with sheer walls, no room for portage and no way back upriver. Powell answered, โ€˜I donโ€™t know.โ€™ Scientific caution was not a factor in this trip; they leapt before looking because there was no way to look first.

Stegner to the contrary, I would argue they survived the way adventurers survive (and sometimes donโ€™t): a kind of adaptive intelligence, for sure, figuring out how to make rotten bacon and moldy flour edible, how to fabricate replacement oars, how to deal with the unexpected quickly and decisivelyBut mostly, just gutting it out, keeping spirits from crashing completely with morbid humor and routines โ€“ Powell getting out the remaining instruments to take their bearing rain or shine, getting back in the boats every morning and turning their lives over to the will of the river again.

And it worked out. Ninety-one days after starting, they made national headlines when they floated half-starved into a town near the confluence with the Virgin River. And Powell, a national hero after that, procured a government job doing a โ€˜surveyโ€™ of the Utah territory.

Then Powell the scientist took over โ€“ but the romantic side of his nature shaped his scientific work. The unstated purpose of the western surveys by the 1870s was to map out potential resources for the fast-growing industrial empire โ€˜back in the statesโ€™; Powell covered those bases, but the heart of his 1879 โ€˜Report on the Lands of the Arid Regionโ€ฆโ€™ was analysis of the potential of the arid lands for fulfilling Jeffersonโ€™s romantic agrarian vision for America. All agricultural activity, he argued, would require irrigation, and there was only enough water to irrigate many three percent of the land.

John Wesley Powell’s recommendation for political boundaries in the west by watershed

He made a strong case for replacing the Homestead Actโ€™s one-size-fits-all 160-acre homestead allotments with two alternatives for the arid lands: 1) 80-acre allotments for intensive irrigated farming, that being as much as a pre-tractor farm family could successfully tend; or 2) โ€˜pasturageโ€™ allotments on unirrigable land of 2,560 acres, four full sections, for stockgrowers, with up to 20 irrigable acres for growing some winter hay and the ubiquitous kitchen garden. He went even further than that: settlement should not be done on a willy-nilly โ€˜first-come-first-served basisโ€™; instead each watershed should be developed by an organized ditch company working from a plan assuring that every member got a fair allotment of water and that the water was most efficiently distributed. And the right to use that water should be bound to the land, he said. No selling your water right to some distant city!

Powell did not just recommend this in his report; he included model bills for state and federal legislation. He was of course thoroughly ignored because everything that he suggested was contrary to the romantic mythology of the Winning of the West โ€“ Jeffersonโ€™s legendary โ€˜yeomanโ€™ conquering the wilderness, the rugged American individualist going forth with rifle, ax and Bible.

Acequia La Vida via Greg Hobbs.

That American mythology from the start was always โ€˜all radiant with the color of romance,โ€™ with very little attention to โ€˜the naked factsโ€™ โ€“  which is the main reason why two out of three homesteads failed as settlement moved into the semi-arid High Plains and the arid interior West. โ€˜The naked factsโ€™ of aridity, on the other hand, had been foundational to the communal land-grant system imported from Spain to Mexico, and it was already known to many of the native peoples already in the Americas: it takes a village and a stream to raise good crops in the arid lands. Powell observed it in the Utah Territory, where the Mormons had borrowed it from the natives and Mexicans.

Powell was philosophical about being ignored โ€“ and kept on pushing. He was โ€˜present at the creationโ€™ of the United States Geological Survey (USGS) in 1879, the same year he presented his โ€˜Report on the Lands of the Arid Region.โ€™ And two years later he became director of the USGS, where he tried to keep both the Agrarian Romanceย andย โ€˜the naked factsโ€™ of aridity front and center. He tried to sell the idea of doing a complete survey of the interior West to map its water resources and the adjacent areas of possibleย successfulย settlement, and he was actually a vote or two from achieving that, and actually shutting down the homesteading process until the study was done. But once some of the senators fronting for the industrialists realized what he was doing, they shut him down with a vengeance โ€“ he quickly realized that to save the USGS, he had to resign from it, and did so in 1894. Western extractive industries depended to some extent on failed homesteaders for their labor supply.

Powell was not out of work, however. From his pre-canyon days he had been interested in the First Peoples of the West. While most Euro-Americans saw them, at best, as raw material for conversion to Christianity and industrial labor, and at worse, as vermin to be wiped off the land, Powell saw them as people who had survived and even thrived in the region with Stone Age technology, some still semi-nomadic, some settled in agrarian communities, and therefore people from whom something might be learned. His efforts to communicate with those he encountered in his Utah survey led to the 1877 publication of a book,ย Introduction to Indian Languages โ€“ย which led, two years later to the creation of the U.S. Bureau of Ethnology in the Smithsonian Institute with Powell as director โ€“ a position he held until his death in 1902, finally producing the firstย comprehensiveย linguistic survey of indigenous tongues,ย Indian Linguistic Families of America, North of Mexico(1891).

In both ethnology and the geology survey Major Powell established a high standard for government science โ€“ attention to the naked facts while still trying to carry forward what Bruce Springsteen called โ€˜the country we carry in our heartsโ€™ โ€“ the ever evolving, devolving, careening, diverted, perverted, and currently severely damaged Romance of the American Dream. Next post, weโ€™ll take a look at what happens when that standard gets out of balance.

But I want to leave you with a Colorado River image of Powell, related in Dellenbaughโ€™s Romance of the Colorado River: there were afternoons in that second voyage in the canyons, in the placid stretches between rapids, when the men would rope the boats together, and Major Powell would sit in his chair on the deck of the Emma Dean and read to them from the romantic adventure stories of Sir Walter Scott. Romancing the River.

January 30, 2026

With just weeks to decide how to share the Colorado Riverโ€™s shrinking water supply, negotiators from seven states hunkered down in a Salt Lake City conference room.ย 

Outside was busy traffic on State Street and South Temple. Inside was gridlock that eased up for a time, only to return, Utahโ€™s chief negotiator, Gene Shawcroft said Tuesday of last weekโ€™s meetings.

The states moved forward on a deal for two-and-a-half days, then went back by almost as far as theyโ€™d come, Shawcroft said. 

โ€œI would just tell you that four days is too long. We got tired of each other,โ€ he said. 

Shawcroft reiterated Tuesday what he and his counterparts from the other Colorado River states have said in recent months: They donโ€™t have a deal, but they do have a commitment to keep talking and meet their upcoming February deadline. 

The earlier goal was to reach a 20-year deal, but Shawcroft told Utah News Dispatch the states are now working on an agreement for a shorter time frame. 

โ€œI think itโ€™ll be fairly simple, but I think itโ€™ll allow us to operate for the next five years,โ€ Shawcroft said.

The river provides water to 40 million people across the U.S. and Mexico, contributing 27% of Utahโ€™s water supply. It is shrinking because ofย drought, [ed. and aridification]overuse and hotter temperatures tied to climate change.

Time for negotiators is also drying up as a Feb. 14 deadline set by the federal government approaches. The current agreement runs through late 2026.

The four Upper Basin states โ€” Utah, Colorado, New Mexico and Wyoming โ€” are at odds with the Lower Basin states of Nevada, Arizona and California.

The upstream states donโ€™t want to make mandatory cuts in dry years, saying they typically use much less than theyโ€™re allocated. The downstream states say all seven need to absorb cuts in difficult years.

Conservation groups have criticized the states for not reaching a deal yet, saying โ€œescalating risksโ€ โ€” including declining storage in lakes Powell and Mead โ€” are piling up every month they fail to agree on a plan.

The debate centers in part on upstream reservoirs like Flaming Gorge on the Utah-Wyoming border and whether theyโ€™ll be managed under the new plan. 

โ€œLower Basin believes those reservoirs ought to be used at the beck and call of the lower basin to reduce their reductions,โ€ Shawcroft said at the meeting. โ€œObviously, we think differently.โ€ 

Arizona Gov. Katie Hobbs, for her part, has criticized the upstream statesโ€™ โ€œextreme negotiating posture,โ€ saying they refuse to participate in any sharing in managing water shortages.

Demand for water is outpacing the riverโ€™s supply, and extended dry periods arenโ€™t helping. At the meeting, board members viewed a map covered in yellow, orange and red, noting the entire Colorado River watershed is experiencing some level of drought. 

Earlier this month, the U.S. Bureau of Reclamation, the federal agency that oversees water in the West,released five options for a framework on managing the riverโ€™s biggest reservoirs, Lake Mead in Nevada and Lake Powell on the Utah-Arizona line.

Amy Haas, executive director of the Colorado River Authority of Utah, said she and her colleagues were still reviewing the 1,600-page document but one thing is clear.  

โ€œNone of the five can provide what for Utah is really the central consideration for the deal, and that is a waiver of compact litigation,โ€ Haas said. 

States can sacrifice more than just time and money in lawsuits over water use. In Texas, similar litigationgave the federal government more leverage in negotiations. 

One of the Bureau of Reclamationโ€™s plans would have Nevada, Arizona and California face potential water shortages. It could go into effect next year if the seven states donโ€™t reach a deal.  

โ€œThe river and the 40 million people who depend on it cannot wait,โ€ Andrea Travnicek, assistant interior secretary for water and science, said in a Jan. 9 statement announcing the five alternatives. โ€œIn the face of an ongoing severe drought, inaction is not an option.โ€

Key Points

  • After negotiators for the seven Colorado River states failed to reach a water-sharing agreement, federal officials have invited governors to continue talks.
  • The feds may impose their own plan if states cannot agree, potentially leading to major cuts for Arizona, with its junior water rights.
  • The states face a mid-February timeline to present a “deal in principle” to replace guidelines expiring in September.

Interior Secretary Doug Burgum has invited all seven governors and their negotiators to meet in Washington in late January, [Tom] Buschatzke said. Perhaps getting the governors face-to-face could lead to a breakthrough, he added..The seven states haveย tried unsuccessfully for more than a yearย to reach a voluntary agreement to replace dam-operating guidelines that will expire with the end of the water year in September. The U.S. Bureau of Reclamation has asked states to submit an agreement by Feb. 14. That date falls on a weekend and likely isnโ€™t a hard deadline for every detail in the plan, Buschatzke said, but a โ€œdeal in principleโ€ probably needs to take shape by then if the states want to control their own destinies.

January 17, 2026

While the four Upper Basin states in the compact โ€” Colorado, New Mexico, Utah, and Wyoming โ€” rely predominantly on snowpack for water supply, the Lower Basin states โ€” Arizona, California, and Nevada โ€” rely on releases from Lake Powell and Lake Mead..Itโ€™s not the compact, but the 2007 operational guidelines for Lake Powell and Lake Mead that are being renegotiated as they are set to expire this year. A decision must be made prior to Oct. 1, 2026, according to the Bureau…The federal government, seven states and 30 tribal nations all agree the best path forward is for a consensus between the upper and lower basins. However, with the looming deadline and unresolved disagreements about the future of the river, the Department of the Interior and its subagency, the Bureau of Reclamation, are forging ahead.ย ย 

โ€‹โ€‹โ€The Department of the Interior is moving forward with this process to ensure environmental compliance is in place so operations can continue without interruption when the current guidelines expire,โ€ said Andrea Travnicek, the assistant secretary of water and science for the Bureau of Reclamation, in a news release announcing the agencyโ€™s latest draft options. โ€œIn the face of an ongoing severe drought, inaction is not an option.โ€ 

One of the main disagreementsย throughout negotiationsย has been who should be making cuts to water use. The Lower Basin states have advocated for basin-wide water use reductions. The Upper Basin states, however, have pushed back on the idea, claiming they already face natural water shortages driven primarily by the ups and downs of snowpack…The draft Environmental Impact Statement released by the Bureau of Reclamation last week offersย five optionsย โ€” including a required โ€œno actionโ€ alternative and four others โ€” that represent a broad range of operating strategies. The draftโ€™s publication initiates a 45-day public comment period ending on March 2, 2026.ย  In a statement, Scott Cameron, acting lead of the Bureau of Reclamation, said that the federal agency has purposefully not identified a preferred alternative, โ€œgiven the importance of a consensus-based approach to operations for the stability of the system.โ€ย  The expectation is that whatever agreement is reached incorporates elements of all five options offered by the Bureau of Reclamation, Cameron added.ย 

The five options identified are: 

  • No Actionย 
  • Basic Coordination
  • Enhanced Coordinationย 
  • Maximum Operational Flexibilityย 
  • Supply Drivenย 


Each option offers differing methods for how the Bureau of Reclamation will operate Lake Powell and Lake Mead, particularly under low reservoir conditions; allocate, reduce or increase annual allocations for consumptive use of water from Lake Mead to the lower basin states; store and deliver water that has been saved through conservation efforts; manage and deliver surplus water; manage activities above Lake Powell; and more.ย

January 15, 2026

Federal officials have released detailed options for how the Colorado River could be managed in the future, pushing forward the planning process in the absence of a seven-state deal. But some Colorado River experts and water managers say cuts donโ€™t go deep enough under some scenarios and flow estimates donโ€™t accommodate future water scarcity driven by climate change.

On Jan. 9, the U.S. Bureau of Reclamation released a draft of its environmental impact statement, a document required by the National Environmental Policy Act, which lays out five alternatives for how to manage the river after the current guidelines expire at the end of the year. This move by the feds pushes the process forward even as the seven states that share the river continue negotiating how cuts would be shared and reservoirs operated in the future. If the states do make a deal, it would become the โ€œpreferred alternativeโ€ and plugged into the NEPA process.

โ€œGiven the importance of a consensus-based approach to operations for the stability of the system, Reclamation has not yet identified a preferred alternative,โ€ Scott Cameron, the acting Reclamation commissioner, said in a press release. โ€œHowever, Reclamation anticipates that when an agreement is reached, it will incorporate elements or variations of these five alternatives and will be fully analyzed in the final EIS, enabling the sustainable and effective management of the Colorado River.โ€ 

For more than two years, the Upper Basin (Colorado, New Mexico, Utah and Wyoming) and the Lower Basin (California, Arizona and Nevada) have been negotiating,ย with little progress, how to manage a dwindling resource in the face of an increasingly dry future. The 2007 guidelines that set annual Lake Powell and Lake Mead releases based on reservoir levels do not go far enough to prevent them from being drawn down during consecutive dry years, putting the water supply for 40 million people in the Southwest at risk.

The crisis has deepened in recent years, and in 2022, Lake Powell flirted with falling below a critical elevation to make hydropower. Recent projections from the U.S. Bureau of Reclamation show that it could be headed there again this year and in 2027.

John Berggren, regional policy manager with Western Resource Advocates, helped craft elements of one of the alternatives, Maximum Operational Flexibility, formerly called Cooperative Conservation.

โ€œMy initial takeaway is thereโ€™s a lot of good stuff in there,โ€ Berggren said of the 1,600-page document, which includes 33 supporting and technical appendices. โ€œTheir goal was to have a wide range of alternatives to make sure they had EIS coverage for whatever decision they ended up with, and I think that there are a lot of innovative tools and policies and programs in some of them.โ€

Alternatives

The first alternative is โ€œno action,โ€ meaning river operations would revert to pre-2007 guidance; officials have said this option must be included as a requirement of NEPA, but doesnโ€™t meet the current needs. 

The second alternative, Basic Coordination, can be implemented without an agreement from the states and represents what the feds can do under their existing authority. It would include Lower Basin cuts of up to 1.48 million acre-feet based on Lake Mead elevations; Lake Powell releases would be primarily 8.23 million acre-feet and could go as low as 7 million acre-feet. It would also include releases from upstream reservoirs Flaming Gorge, Blue Mesa and Navajo to feed Powell. But experts say this alternative does not go far enough to keep the system from crashing. 

โ€œIt was pretty well known that the existing authorities that Reclamation has are probably not enough to protect the system,โ€ Berggren said. โ€œEspecially given some of the hydrologies we expect to see, the Basic Coordination does not go far enough.โ€

Theย Enhanced Coordination Alternativeย would impose Lower Basin cuts of between 1.3 million and 3 million acre-feet that would be distributed pro-rata, based on each stateโ€™s existing water allocation. It would also include an Upper Basin conservation pool in Lake Powell that starts at up to 200,000 acre-feet a year and could increase up to 350,000 acre-feet after the first decade.

Under the Maximum Operational Flexibility Alternative, Lake Powell releases range from 5 million acre-feet to 11 million acre-feet, based on total system storage and recent hydrology, with Lower Basin cuts of up to 4 million acre-feet. It would also include an Upper Basin conservation pool of an average of 200,000 acre-feet a year. 

These two alternatives perform the best at keeping Lake Powell above critical elevations in dry years, according to an analysis contained in the draft EIS. 

โ€œThere are really only two of these scenarios that I think meet the definition of dealing with a very dry future: Enhanced Coordination and the Max Flexibility,โ€ said Brad Udall, a senior water and climate research scientist at Colorado State University. โ€œThose two kind of jump out at me as being different than the other ones in that they actually seem to have the least harmful outcomes, but the price for that are these really big shortages.โ€

The final scenario is the Supply Driven Alternative, which calls for maximum shortages of 2.1 million acre-feet and Lake Powell releases based on 65% of three-year natural flows at Lees Ferry. It also includes an Upper Basin conservation pool of up to 200,000 acre-feet a year. This option offers two different approaches to Lower Basin cuts: one based on priority where the oldest water rights get first use of the river, putting Arizonaโ€™s junior users on the chopping block, and one where cuts are distributed proportionally according to existing water allocations, meaning California could take the biggest hit. 

This alternative is based on proposals submitted by each basin and discussions among the states and federal officials last spring. Udall said the cuts are not deep enough in this option.

โ€œYou can take the supply-driven one and change the max shortages from 2.1 million acre-feet up to 3 or 4 and itโ€™s going to perform a lot like those other two,โ€ he said. โ€œI think what hinders it is just the fact that the shortages are not big enough to keep the basin in balance when push comes to shove.โ€

Pivotal moment

In a prepared statement, Glenwood Springs-based Colorado River Water Conservation District officials expressed concern that the projected future river flows are too optimistic.  

โ€œWe are concerned that the proposed alternatives do not accommodate the probable hydrological future identified by reliable climate science, which anticipates a river flowing at an average of 9-10 [million acre feet] a year,โ€ the statement reads. โ€œThe Colorado River Basin has a history of ignoring likely hydrology, our policymakers should not carry this mistake forward in the next set of guidelines.โ€

The River District was also skeptical of the Upper Basin conservation pool in Lake Powell, which is included in three of the alternatives. Despite dabbling in experimental programs that pay farmers and ranchers to voluntarily cut back on their water use in recent years, conservation remains a contentious issue in the Upper Basin. Upper Basin water managers have said their states canโ€™t conserve large volumes of water and that any program must be voluntary. 

Over the course of 2023 and 2024, the System Conservation Pilot Program, which paid water users in the Upper Basin to cut back, saved about 101,000 acre-feet at a cost of $45 million.

The likeliest place to find water savings in Colorado is the 15-county Western Slope area represented by the River District. But if conservation programs are focused solely on this region, they could have negative impacts on rural agricultural communities, River District officials have said.

โ€œAdditionally, several alternatives include annual conservation contributions from the Upper Basin between [200,000 acre-feet] and [350,000 acre feet],โ€ the River Districtโ€™s statement reads. โ€œWe do not see how that is a realistic alternative given the natural availability of water in the Upper Basin, especially in dry years.โ€

In a prepared statement, Colorado officials said they were looking forward to reviewing the draft EIS.

โ€œColorado is committed to protecting our stateโ€™s significant rights and interests in the Colorado River and continues to work towards a consensus-based, supply-driven solution for the post-2026 operations of Lake Powell and Mead,โ€ Coloradoโ€™s commissioner, Becky Mitchell, said in the statement.

The release of the draft EIS comes at a pivotal moment for the Colorado River Basin. The seven state representatives are under the gun to come up with a deal and have less than a month to present details of a plan by the fedsโ€™ Feb. 14 deadline. Federal officials have said they need a new plan in place by Oct. 1, the start of the next water year. This winterโ€™s dismal snowpack and dire projections about spring runoff underscore the urgency for the states to come up with an agreement for a new management paradigm. 

Over a string of recent dry years, periodic wet winters in 2019 and 2023 have bailed out the basin and offered a last-minute reprieve from the worst consequences of drought and climate change. But this year is different, Udall said.

โ€œWeโ€™re now at the point where weโ€™ve removed basically all resiliency from the system,โ€ he said. โ€œBetween the EIS and this awful winter, some really tough decisions are going to be made. โ€ฆ Once we finally get to a consensus agreement, the river is going to look very, very different than it ever has.โ€

The draft EIS will be published in the Federal Register on Jan.16, initiating a 45-day comment period that will end March 2.

January 15, 2026

Absent a crucial but elusive consensus among the sevenย Colorado Riverย states, federal authorities are forging ahead with their own ideas on how to divvy up painful water cuts as climate change diminishes flows in the critical river. The Bureau of Reclamation last week made public a 1,600-page behemoth of a document outlining five potential plans for managing the river after current regulations expire at the end of this year. The agency did not identify which proposal it favors, in hopes that the seven states in the river basin will soon come to a consensus that incorporates parts of the five plans. But time is running out. The states โ€” Colorado, Wyoming, Utah, New Mexico, California, Arizona and Nevada โ€”ย already blew past a Nov. 11 deadlineย set by federal authorities to announce the concepts of such a plan. They now have until Feb. 14 to present a detailed proposal for the future of the river that makes modern life possible for 40 million people across the Southwest. They were set to meet this week in Salt Lake City to continue negotiations. Federal authorities must finalize a plan by Oct. 1…

โ€œThe Department of the Interior is moving forward with this process to ensure environmental compliance is in place so operations can continue without interruption when the current guidelines expire,โ€ Andrea Travnicek, the assistant secretary for water and science at the Department of the Interior, said in a news release announcing the document.  โ€œThe river and the 40 million people who depend on it cannot wait. In the face of an ongoing severe drought, inaction is not an option.โ€

A 45-day public comment period opens Friday onย the proposed plansย for managing the river system, contained in a document called a draft environmental impact statement. The current operating guidelines expire at the end of 2026, but authorities need a replacement plan in place prior to the Oct. 1 start to the 2027 water year. The water year follows the water cycle, beginning as winter snowpack starts to accumulate and ending Sept. 30, as irrigation seasons end and water supplies typically reach their lowest levels…

Already, Lake Mead โ€” on the Arizona-Nevada border โ€” and Lake Powell are only 33% and 26% full, respectively. Projections from the Bureau of Reclamation show that, in a worst-case scenario, Powellโ€™s waters could fall below the level required to run the damโ€™s power turbines by October and remain below the minimum power pool until June 2027. Experts monitoring the yearslong effort to draft new operating guidelines said any plan implemented by Reclamation must consider the reality of a river with far less water than assumed when the original river management agreements were signed more than a century ago.

The Colorado River’s Reaches

Post by Robert Marcos (Robert Marcos Studio):

By now everybody’s sick and tired of the term “Dead Pool”. But what about reaches? Last summer as I was driving from Denver to Grand Junction I was horrified to see that the Mighty Colorado that had been flowing outside my left window had suddenly dried up, completely. This was nine miles east of Glenwood Springs. The view of the dessicated riverbed reminded me of a scene from a post-apocalyptic movie.

The culprit of course was the Shoshone Hydroelectric Generating Station which diverts 1250 cfs from a diversion at Hanging Lake, then returns that water 2-1/2 miles downstream after it’s been used to drive the plant’s hydroelectric turbines.

As the name implies Grand Junction’s “15 mile reach” is much longer. In the late summer a full 15-miles of dry river bottom can be seen along the I-70 beginning at the Cameo Diversion Dam and ending 15 miles downstream at the confluence of the Gunnison River. The Cameo Diversion Dam supplies 1.2 million acre feet of river water annually to irrigate Grand Valley farms, then returns about half of that water to the Colorado river at a variety of points downstream.

Not surprising these dry patches are hell for native fish, at least four of which are on the verge of extinction. The Bonytail – which has no wild populations left, the Colorado Pikeminnow, the Razorback Sucker, and the Humpback Chub, are all critically imperiled due to habitat loss from dams and competition from non- native species.

Gratefully one organization has ponied up to keep the water flowing. The Colorado Water Trust uses donations from people like me to buy water from sources that are upstream of these reaches in order to maintain a limited amount of water flow, year round. It may not be much but they’re hoping it’s enough to keep these fish, and many other aquatic species alive through the summer.

I can’t help but wonder whether those who are responsible for managing the river couldn’t do more to balance its many uses in order to ensure that the river’s ecological health isn’t left hanging by such a fragile thread.

Reclamation releases draft environmental review for post-2026 #ColoradoRiver operations: Process advances planning for future river management amid prolonged #drought and ongoing negotiations #COriver #aridification

Click the link to read the release on the Reclamation website:

January 9, 2026

The Bureau of Reclamation today released a draft Environmental Impact Statement evaluating a range of operational alternatives for managing of Colorado River reservoirs after 2026, when the current operating agreements expire. The draft EIS evaluates a broad range of potential operating strategies. It does not designate a preferred alternative, ensuring flexibility for a potential collective agreement. 

 Prolonged drought conditions over the past 25 years, combined with forecasts for continued dry conditions, have made development of future operating guidelines for the Colorado River particularly challenging. 

 โ€œThe Department of the Interior is moving forward with this process to ensure environmental compliance is in place so operations can continue without interruption when the current guidelines expire,โ€ Assistant Secretary – Water and Science Andrea Travnicek said.  “The river and the 40 million people who depend on it cannot wait. In the face of an ongoing severe drought, inaction is not an option.โ€ 

ย The draft EIS evaluates a broad range of operational alternatives for post-2026 reservoir management informed through input and extensive collaborative engagement with stakeholders, including the seven basin states, tribes, conservation organizations, other federal agencies, other Basin water users, and the public. It includes the following alternatives that capture operational elements and potential environmental impacts:

  • No Actionย 
  • Basic Coordinationย 
  • Enhanced Coordinationย 
  • Maximum Operational Flexibilityย 
  • Supply Drivenย 

The document will be published in the Federal Register on January 16, 2026, initiating a 45-day comment period that will end on March 2, 2026. The draft EIS and additional information on the alternatives are available on Reclamationโ€™s website.  

 “Given the importance of a consensus-based approach to operations for the stability of the system, Reclamation has not yet identified a preferred alternative,” said Acting Commissioner Scott Cameron. “However, Reclamation anticipates that when an agreement is reached, it will incorporate elements or variations of these five alternatives and will be fully analyzed in the Final EIS enabling the sustainable and effective management of the Colorado River.” 

 The Colorado River provides water for more than 40 million people and fuels hydropower resources in seven states. It serves as a vital resource for 30 Tribal Nations and two Mexican states, sustaining 5.5 million acres of farmland and agricultural communities throughout the West, while also supporting critical ecosystems and protecting endangered species.  

 The Draft EIS addresses only domestic river operations. A separate binational process addressing water deliveries to Mexico is underway and the Department is committed to continued collaboration with the Republic of Mexico. The Department will conduct all necessary and appropriate discussions regarding post-2026 operations and implementation of the 1944 Water Treaty with Mexico through the International Boundary and Water Commission in consultation with the Department of State. 

 To provide certainty for communities, tribes, and water users, a decision regarding operations after 2026 will be made prior to October 1, 2026 โ€“ the start of the 2027 water year.

Key Takeaways

  • The consensus-based effort to develop new rules to manage the Colorado River system hasnโ€™t worked โ€“ itโ€™s time for a new approach
  • Federal leadership and the credible threat of managing reservoirs to protect the system is that new approach

Missing Deadlines

Way back at the end of the last century, at the annual Colorado River conference in Vegas, Marc Reisner repeated the Margaret Thatcher quote that consensus is the absence of leadership. On Veterans Day, the seven Colorado River basin states missed yet another deadline to reach consensus on a conceptual plan for managing the shrinking Colorado River after the current rules expire in 2026. Valentineโ€™s Day marks the next holiday deadline, this time for a detailed plan, but multiple missed deadlines give no indication that the states will reach consensus then, either.

The basin states canโ€™t agree on the substance of a new agreement. They also disagree on the process to get there. While Arizona has called for the federal government to break the negotiation logjam, Colorado opposes federal intervention and continues to call for consensus. Each basin-state negotiator acts to protect their stateโ€™s interests, often at the expense of the short and long-term resilience of the Colorado River system as a whole and the 35 million people who rely on it. The continued failure to negotiate a plan challenges the efforts of irrigators, cities, businesses, and river runners throughout the basin to plan for 2027 and beyond.

Meanwhile, river runoff and reservoir storage get lower and lower and snowpack lags well below average. This is not a zero-sum game, with winners and losers. The more appropriate metaphor here is a shrinking pie, with smaller and smaller pieces.

Leadership

The basin state negotiators have met for years behind closed doors, without success. Itโ€™s time for a new approach. Aggressive federal intervention and the credible threat of a federally-imposed Colorado River management plan would offer political cover โ€“ or a political imperative โ€“ for the negotiators. The credible threat of a federal plan would give the negotiators the space to compromise without having to do so unilaterally and then being accused of not protecting their stateโ€™s interests.

But federal leadership alone is not enough โ€“ it must be coupled with a plausible federal plan that compels the states to act and can meet the magnitude of the ongoing crisis. As the Department of the Interior announced in its 6/15/2023 press release, the purpose of and need for the post-2026 guidelines is โ€œto develop future operating guidelines and strategies to protect the stability and sustainability of the Colorado River.โ€ To date, the development of the post-2026 guidelines has prioritized routine operations of Glen Canyon and Hoover dams over the system as a whole, a focus inconsistent with the magnitude and urgency of the problem. Prioritizing routine dam operations and hydropower generation over water delivery and environmental protection elevates the tool over the task. Seeking to preserve routine operations of the dams while imposing draconian cuts on water users is not a path to resilience and precludes alternatives that would help stabilize the system.

The Plan

Instead, by early next year, the Secretary should announce that Interior will implement a federal plan incorporating the following elements:

  1. Grant Tribal Nations the legal certainty and the ability to access, develop, or lease their water.
  2. Make accessible (โ€œrecoverโ€)ย the roughly 5.6 million acre-feet (MAF)ย of water stored in Lake Powell below the minimum power pool elevationย and avoid the additional ~0.25 MAF of annual evaporative losses from Powell by storing such water in Lake Mead and using Powell as auxiliary storage.
  3. As a condition precedent, the Lower Basin states agree not to place a โ€œcompact callโ€ for the duration of the agreement.
  4. Implement annual Lower Basin water use reductions for the following calendar year based on total system contents on August 1:
    • 75% โ€“ 60%: cuts to Lower Basin water uses increasing from 0 to 1.5 MAF<60% โ€“ 38%: static cut to Lower Basin water uses of 1.5 MAF<38% โ€“ 23%: increasing cuts to Lower Basin water uses of up to 3.0 MAF total
    • below 23% of total system contents โ€“ cut Lower Basin water uses to the minimum required to protect human health and safety and satisfy present perfected rights
  5. If the Lower Basin states do not satisfy the condition precedent in #3 above, Reclamation limits Lower Basin deliveries to the minimum required to satisfy present perfected rights when total system contents are <75%.
  6. Recover water stored in federal Upper Basin reservoirs unless the Upper Basin states reduce annual water use based on total system contents:
    • <34% โ€“ 23%: Assuming the first 0.25 MAF โ€œreductionโ€ would be contributed by the elimination of Powellโ€™s evaporative losses and gains from Glen Canyon bank storage, reduce Upper Basin water uses up to 0.65 MAF
    • below 23% of total system contents โ€“ limit total Upper Basin water uses to 3.56 MAF (the minimum volume reported this century)
  7. Expand the pool of parties eligible to create Intentionally Created Surplus (ICS) beyond existing Colorado River contractors, to include water agencies and other entities with agreements to use Colorado River water.
  8. Eliminate the existing limits on the total quantity ofย Extraordinary Conservation ICS and DCP ICSย that may be accumulated in ICS and DCP ICS accounts, while maintaining existing limits on delivery of such water.
  9. Fully mitigate the on-stream and off-stream community and environmental impacts of the water use reductions identified above.
  10. After a three-year phase-in period, condition Colorado River diversions on a clear โ€œreasonable and beneficial useโ€ standard predicated on existing best practices for water efficiency, including but not limited to the examples listed below (state(s) that already have such standards):
  • Require removal of non-functional turf grass (California, Nevada)
  • Incentivize landscape conversion and turf removal statewide (California, Colorado, Utah)
  • Adopt stronger efficiency standards for plumbing and equipment (Colorado, California, and Nevada)
  • Require urban utilities to report distribution system leakage, and to meet standards for reducing water losses (California)
  • Require all new urban landscapes to be water-efficient (California)
  • Require metering of landscape irrigation turnouts (Utah)
  • Ensure that existing buildings are water-efficient when they are sold or leased (Los Angeles, San Diego)
  • Require agricultural water deliveries to be metered and priced at least in part by volume (California)

Many of the elements listed above raise important questions about federal authorities, accounting and data challenges, the roles and obligations of state water officials to implement coordinated actions in-state, water access for disadvantaged communities, environmental compliance, and potential economic and social costs, among others. For each item listed, many details will need to be refined. Similarly, the planโ€™s duration will need to be determined. But as temperatures again climb into the high 40s in the Rockies near the Colorado Riverโ€™s headwaters (in mid-December!), drying soils and reducing next yearโ€™s runoff, and the National Weather Service issues red flag fire warnings for Coloradoโ€™s Front Range, the need for bold action is clear.

The Dominy Bypass

Recovering water stored in Lake Powell will require the construction of new bypass tunnels around Glen Canyon Dam. Former Reclamation Commissioner Floyd Dominy sketched the design of such tunnels almost thirty years ago (see image). Such tunnels would enable the recovery of about 5.6 MAF of water stored below the minimum power pool elevation โ€“ more water than the Upper Basin states consume each year. Current operating rules and the scope of the current planning process effectively treat this massive volume of water as โ€œdead storageโ€ โ€“ a luxury the system can no longer afford. After Reclamation constructs the bypass tunnels, water recovery should be timed to maximize environmental and recreational benefits in the Grand Canyon.

Avoiding a Worse Outcome

Last yearโ€™s Colorado River conference featured a panel on the risks of litigation. Unfortunately, the continued failure to reach a dealgrowing litigation funds, and the preference for repeating the same action thatโ€™s led to the continuing impasse suggest that some believe litigation could generate a better outcome (for them). Both sides have attorneys who assure their clients of victory. Yet, as Arizona learned in 1968winning in the Supreme Court doesnโ€™t ensure a better outcome and certainly wonโ€™t increase Colorado River flows. Placing faith in Congress could entangle this basin with challenges in other basins and other political considerations.

Running the River

Almost 160 years ago, John Wesley Powell โ€“ the reservoirโ€™s namesake โ€“ demonstrated bold leadership, going where no (white) man had gone before. With leadership and a clear goal, he charted a route through the Colorado Riverโ€™s iconic canyons. Now is the time for more bold leadership, a clear goal, and a plan to get there.

January 5, 2025

A recent study by Colorado Parks and Wildlife and a Colorado Springs Tribune article by Jonathan Ingraham have raised concerns about the adverse effects certain whitewater parks might have on local fish populations โ€“ but local CPW officials said they are pleased to report Salida and Buena Vistaโ€™s parks arenโ€™t among them. For Salidaโ€™s Scout Wave, CPW collaborated with Mike Harveyโ€™s company to design the fish passage part of the wave, CPW aquatic biologist Alex Townsend said. โ€œIt definitely took some forethought.โ€ Though there are examples of whitewater parks that are not built with fish welfare in mind, Townsend said the parks in Salida and Buena Vista are built that way, and other whitewater park designers need to be sure to work with biologists and wildlife experts…

When building the fish passage, they have a gradient that extends a little further than the wave itself, with planned drops and pools below those drops. They also created rough elements, which create vortices for the fish to have flow refuge, he explained, resulting in the fish passage being nowhere near the same velocity as the wave…

Mike Harvey, project manager of Recreation and Engineering Planning, who constructed the Scout Wave and fish passage, said, โ€œWeโ€™ve been working with CPW over 15 years. This is not something that is new to us.โ€ In regards to the Tribune article, he said, โ€œItโ€™s a little surprising that this is coming up again,โ€ he said…

Building the fish passage did not require any extra labor on their part, nor was it difficult, he said. โ€œYouโ€™re going to set rocks anyway, so you just set them in the configuration that they need.โ€

A mayfly loving trout โ€” speckled, shiny and perfectly hand-sized for that Instagram hero shot. A five-foot-long torpedo of a predator, capable of powering through floodwaters and migrating hundreds of miles. A three-inch minnow, living only a couple of years and content with life in a small pool in an ephemeral creek. Which fish is the true Colorado native?

The answer is all of them. A state with waterways as diverse as Coloradoโ€™s has naturally produced a diverse assortment of native fish to match. We have cutthroat trout, lovers of pristine, high-elevation streams on both sides of the Continental Divide. Large, long-lived species like Colorado pikeminnow and humpback chub fight their way through the whitewater of the Western Slope. Tiny brassy minnows and redbelly dace ply the shallow, sandy creeks of the Eastern Plains. Each is adapted to its own ecological niche, body and behavior tailored to its particular home waters and the other aquatic creatures that evolved alongside it.

Humans have dramatically altered this delicate balance in a very short time span. While some native populations still thrive, many others struggle as their habitats and predators have changed. Starting a couple of hundred years ago, mining pollution, overfishing, and haphazard stocking of non-native fish led some Colorado species to plummet, or even go extinct. Today, native fish still grapple with climate change, dams, water diversions, and competition with invasive species. But humans are also working to turn back the clock and restore these native species. Follow along on this tour of Coloradoโ€™s waterways, meeting our home-state fish โ€” and learning what it takes to help them endure.

Headwaters

Letโ€™s begin where the rivers do: high in the Rocky Mountains, where clean, cold streams form and flow downhill, eventually feeding the stateโ€™s largest rivers. This is the realm of Coloradoโ€™s poster fish, the cutthroat trout. Colorful, beautiful and beloved by anglers, cutthroats โ€” recognizable by the iconic red slash markings under the jaw that give the species its name โ€” live in the headwaters of almost every river basin in the state. Cutthroat trout are at home where thereโ€™s oxygenated water, gravelly bars for spawning, and good vegetative cover on stream banks.

โ€œCutthroat troutโ€ isnโ€™t just one type of fish in Colorado, but rather, six. Thereโ€™s the greenback cutthroat trout, originally from the South Platte River Basin on the east side of the Divide. The yellowfin cutthroat came from the Arkansas River Basin, but is now considered extinct. Moving southwest, the Rio Grande cutthroat rose from the Rio Grande Basin. Then, on the Western Slope, the Colorado River cutthroat is further divided into three lineages: the Green River lineage, found in the Green, White and Yampa rivers; the Uncompahgre lineage, of the Dolores, Gunnison and Upper Colorado rivers; and the San Juan lineage, of the San Juan River Basin.

Thatโ€™s not to say the average angler โ€” or indeed, the average fish biologist โ€” can tell the cutthroats apart just by looking at them. Nor can they be identified based on where theyโ€™re caught these days. Humans, from regular people trying to create new fishing opportunities to professional fisheries managers, spent much of the last couple of centuries moving cutthroats around the state with little understanding of the differences between subspecies. โ€œItโ€™s really hard to put the genie back in the bottle once that happens,โ€ says Jim White, southwest senior aquatic biologist for Colorado Parks and Wildlife (CPW). โ€œOne of the great mysteries in cutthroat trout distributions was, what went where? What did these river basins look like before we started widespread stocking of cutthroats and non-natives?โ€

Biologists didnโ€™t know the answer until 2012, when a landmark study led by University of Colorado Boulder researchers conducted DNA analysis on museum fish specimens gathered at the beginning of European contact with the West. Those results confirmed the existence of the six genetically distinct types of cutthroat โ€” five previously known to science, and one brand-new one, the San Juan lineage trout. The study speculated that San Juan cutthroats had also gone extinct, but CPW biologists had to be sure. โ€œWe beat the bushes, surveyed all the populations, and conducted molecular tests on fin clips from all known cutthroat trout populations in the San Juan Basin,โ€ says Kevin Rogers, CPW aquatic research scientist and co-author on the 2012 genetic study. โ€œIndeed, there were about a half-dozen populations that [matched] the fish that had been collected in the mid- to late 1800s.โ€

One thing all five remaining Colorado cutthroat varieties have in common is a reduction in the amount of habitat they occupy. The stateโ€™s cutthroats are now relegated to just 12% of their historical habitat on the high end, down to half a percent on the low end, says Boyd Wright, native aquatic species coordinator with CPW. โ€œMost of the lower elevations have been invaded by non-native trout, so cutthroats are persisting only in the headwaters,โ€ Rogers says. Greenback cutthroats are federally listed as threatened, and Rio Grande and Colorado River cutthroats (occupying just 12% and 11% of their historic habitat, respectively) are state species of special concern. The culprits? What began with pollution, overharvesting and the stocking of non-native fish in the era of Western colonization continues today.

Non-native fish pose a major threat to native cutthroats, particularly the brown, brook and rainbow trout that have been stocked statewide and now thrive in Coloradoโ€™s waters. โ€œTo sum it up, thereโ€™s hybridization, thereโ€™s predation, and thereโ€™s competition,โ€ White says. โ€œAll of those three things can interact to disadvantage our native fish populations.โ€ Rainbow and cutthroat trout can breed, resulting in the hybrid cutbow. Non-native trout sometimes even eat the natives. They also compete with cutthroats for food, and often win. Brook and brown trout spawn in the fall and hatch in the spring โ€” so when the cutthroat fry hatch in late summer, their non-native rivals have already had several months to grow bigger.

Climate change isnโ€™t helping. โ€œWe have the two ugly stepchildren that come along with a changing climate: drought and wildfire,โ€ Rogers notes. โ€œThe toll wildfire can take on cutthroat is substantial. The debris flows that invariably happen afterward can wipe out populations.โ€ Drought can also lower or dry up streams, further contracting ranges.

But CPW and partner organizations like the U.S. Fish and Wildlife Service are actively working to conserve Coloradoโ€™s native cutthroats. Biologists raise the trout in hatcheries for stocking back in their native streams, but thereโ€™s a lot more to it than that. First, managers must prep the waterways by removing non-native trout, often by poisoning with natural fish toxicants, a process that can take years. Any present pathogens, like whirling disease, must be eradicated. Managers also have to make sure non-native fish canโ€™t reinvade the stream, usually by building a barrier, like a waterfall. Despite the difficulty and expense, the state is actively working on recovery projects for all five cutthroat varieties. โ€œThatโ€™s what weโ€™re about, trying to preserve diversity for future generations to enjoy,โ€ Rogers says.

Desert Rivers

As the mountain streams follow gravity into the western lowlands, they flow into larger networks: Rivers like the Yampa, White and Animas feed the desert arteries of the Green and San Juan, and these, together with the Gunnison, Dolores and others join the Colorado. The entire basin touches seven states, from Wyoming and Colorado up north to Arizona and California in the southwest.

The cold swift headwaters give way to rivers that historically swung between huge springtime floods and slow, turbid flatwater. And the trout give way to large, long-lived fish with bodies suited to big water and wild rapids.

Just over a dozen fish species evolved with the chops to survive in the larger rivers within the Colorado River system. Three of them, called just โ€œthe three speciesโ€ by biologists, are the flannelmouth sucker, bluehead sucker, and roundtail chub. These omnivorous swimmers persist in todayโ€™s rivers, though managers keep a close eye on conserving their populations so that they donโ€™t go the way of four other native species.

These four โ€” all federally listed as endangered or threatened โ€” have struggled in the face of drastic, human-caused changes to their habitats. The bonytail, a large-finned, skinny-tailed omnivore, is the worst off, with no sustainable wild populations left. Its relative, the humpback chub, sports a pronounced bump behind its head, all the better to stabilize the fish in whitewater. Its populations have stayed stable over the past few years, with most of them found near the Grand Canyon, and the species was downlisted from endangered to threatened in 2021. The Colorado pikeminnow, a powerful swimmer shaped like a missile, is the largest minnow in North America. It can migrate 200 miles annually and lives 40 years or more. Its numbers are slowly increasing in the Upper Colorado and San Juan subbasins, but are declining in the Green River. And the razorback sucker, a bug- and plankton-eater, features a similar keel behind its head that helps it maneuver through high flows.

All four populations have crashed in response to human water use and reduced water availability resulting from drought and climate change, which has altered the habitats they once inhabited. โ€œWe have cross-basin diversions that feed water from the Western Slope over to the Front Range,โ€ says Jenn Logan, native aquatic species manager for CPW. โ€œWe donโ€™t have the volume of water that we used to see in the spring. With dams and water going into ditches and filling reservoirs, runoff is nowhere near where it used to be. We donโ€™t have sandbars formed in the way that we used to, and these systems relied on sediment to form complex habitats.โ€ Not only that, but dams change water temperature, with released water alternately cooling or warming the river downstream depending on where in the reservoir it comes from. And of course, they form a physical barrier for fish that evolved migrating through a huge, interconnected river system.

Then thereโ€™s the non-native interlopers โ€” primarily smallmouth bass, northern pike, walleye, and green sunfish โ€” all introduced, either purposely or accidentally, by humans looking for expanded angling opportunities. โ€œTheyโ€™re predatory species โ€” they get in the river and can really compete with and consume the native fish in the Colorado River,โ€ says Josh Nehring, deputy assistant director, aquatic branch, of the CPW fish management team. All have found happy homes in the modern Colorado River Basin with its dams, reservoirs and warmer waters.

But just as in the mountain streams, fisheries managers on the Western Slope are working aggressively to protect the natives. The Upper Colorado River Endangered Fish Recovery Program and the San Juan River Basin Recovery Implementation Program oversee the recovery of the four fish species listed as threatened or endangered. The recovery programs are coalitions of water users, federal, state and tribal agencies, plus nonprofits and energy organizations. They take steps like installing nets at the edge of reservoirs to keep non-natives contained and stocking sterile non-native fish in reservoirs to keep them from establishing a population if they do get out. Other work looks like electrofishing stretches of river โ€” that is, introducing a current that stuns fish in the water โ€” and physically removing the non-natives, leaving the native fish to recover and swim another day; and gillnetting northern pike in their springtime spawning habitats. Water managers go so far as to recontour river channels on the upper Yampa to cut off access to northern pikeโ€™s spawning wetlands.

Dam management is another useful tool for both helping native fish and disadvantaging the non-natives. The Upper Colorado River Endangered Fish Recovery Program works with the U.S. Bureau of Reclamation at Utahโ€™s Flaming Gorge Dam on the Green River on timed releases โ€” releasing water when biologists detect the yearโ€™s razorback sucker larvae โ€œto attempt to move them down to their wetland habitats,โ€ Logan says. Theyโ€™ll release water to disrupt smallmouth bass nesting, when possible. And in the Lower Basin downstream of Lake Powell, managers have begun releasing cooler water specifically to make the Colorado River there less hospitable to smallmouth bass. As long-term drought has dropped water levels in Lake Powell, โ€œWeโ€™ve been seeing increases in water temperature releases coming through the dam,โ€ says Ryan Mann, aquatic research program manager for the Arizona Game and Fish Department. Some smallmouth bass made their way into the river below the dam in years past, but the water had been cold enough to keep them from reproducing. But in 2022, biologists found baby bass. Last summerโ€™s cold-water releases prevented widespread spawning, and managers may continue them into the future.

Todayโ€™s Colorado River Basin is a radically different place than in centuries past, and, โ€œUnless thereโ€™s some amazing technology that comes along to remove all non-native fish or a way to return flows to historic conditions weโ€™re not going to be able to move [major river systems] back to native fish,โ€ Nehring says. But that doesnโ€™t mean those species are doomed. CPW and its partners are actively raising threatened species in hatcheries and reintroducing them to targeted habitats. โ€œWeโ€™re really focusing on the tributaries, to keep the natives alive in enough areas where we know theyโ€™ll persist,โ€ Nehring says.

As alpine streams flow east, they meander through Front Range cities, then spread across the arid plains. The water warms, rocky beds grow sandy, and habitats shrink as creeks dry up seasonally. Waters dominated by a single species explode with different fish. โ€œWeโ€™ve got this melting pot of biological diversity along the transition zone,โ€ says Wright. โ€œYou go from historically a one-species profile in the mountains to more than 28 as you go farther east. These [plains] are very harsh, unpredictable environments.โ€

The fish that evolved to thrive on the plains, from the regionโ€™s western edges in Colorado out into Kansas, Oklahoma and Nebraska, are largely the opposite of the big, long-lived species on the Western Slope. Theyโ€™re a few inches long, live just a couple of years, and reproduce early. These fish are used to biding their time in small pools until rain or spring runoff reconnects the intermittent creeks, finally allowing them a change of scenery.

But the Eastern Plains havenโ€™t escaped the challenges affecting Coloradoโ€™s other rivers โ€” its native fish are struggling, too. โ€œMost of our plains fishes are declining or locally extinct because of habitat modification or loss,โ€ says Ashley Ficke, fisheries ecologist with engineering firm GEI Consultants. Humans have diverted water to farms and municipalities, redirected streams into straight channels lacking habitat complexity, and even drained some waters completely. That hits fish like the plains minnow particularly hard, as its semi-buoyant eggs float vast distances between spawning grounds and ideal nursery habitat. โ€œIt needs vast portions of unfragmented stream habitat,โ€ Wright says. โ€œWeโ€™ve really lost that in Colorado, and thatโ€™s a big reason why theyโ€™re very rare.โ€

As elsewhere in the state, though, fish managers are working to replenish the swimmers of the plains. At a hatchery in Alamosa, CPW breeds 12 rare native fish, half of them eastern species: plains minnow, suckermouth minnow, northern and southern redbelly dace, Arkansas darter, and common shiner. โ€œWeโ€™re working with private landowners that have streams or ponds that would be suitable for these native fish, working with them to maintain or improve that habitat, and stocking those waters with the native fish,โ€ Nehring says. By preserving and restoring enough of the plainsโ€™ stream habitats, managers hope to give back sufficient waters for these little fish to persist.

โ€˜Sustainabilityโ€™ is a foundational tenet of modern natural resource management. The concept of sustainable development gained global recognition in 1987 when the United Nationsโ€™ Brundtland Commission published its report on Our Common Future, in which sustainable development was defined as โ€œmeeting the needs of the present without compromising the ability of future generations to meet their own needs.โ€ In simple terms, this means avoiding the depletion of natural resources and loss of species over time.

Brian Richter

Our research group has just published our third detailed assessment of water resources management in three major river basins in the western United States. Our three studies โ€” focusing on the Colorado River, the Great Salt Lake basin, and the Rio Grande-Bravo โ€” clearly document that water managers and political leaders are failing in their efforts to manage these water resources for long-term sustainability, meaning that they have not balanced water consumption with natural replenishment from snowmelt runoff, rainfall, and aquifer recharge. As a result, reservoir and groundwater levels are falling, rivers are shriveling, and numerous endangered species are in great jeopardy. The livelihoods and well-being of tens of millions of people dependent on these water systems, along with the extraordinary ecological systems and species sustained by these waters, are now at great risk.

As a Native American friend said recently, โ€œour world is out of balance.โ€

These systemic failures share a common history with hundreds of other stressed river basins and aquifers around the planet. For thousands of years, the human populations dependent on each water source were small enough that water consumed for human endeavors had little to no impact on water sources and associated ecosystems, i.e., their use of water was โ€˜renewableโ€™ and โ€˜sustainable.โ€™ But over the course of the 20th century, the growth of human populations and associated food needs grew rapidly โ€” largely without constraint or control โ€” to the point of consuming all of the renewable annual water supplies in many river basins, including the three we studied. Then as we entered into the 21st century, climate warming began reducing the replenishment of rivers, lakes, and aquifers. The balance between water consumption and replenishment became overweighted on the consumption side as the replenishment side got lighter. Our world went out of balance.

The Risks of Continued Imbalance Are Very Frightening

The potential consequences of this imbalance are nothing short of horrific and dangerous in the three basins we studied. Here are some of the highlights from our trilogy of recent papers:

Colorado River “Beginnings”. Photo: Brent Gardner-Smith/Aspen Journalism
  • Colorado River Basin:ย Since 2000, more water has been consumed than replenished in this basin in three out of every four years, on average. These recurring deficits in the basinโ€™s annual water budget has been offset by depleting water stored in the basinโ€™s reservoirs and aquifers, analogous to pulling money out of a savings account to make up for overdrafts in a checking account. As a result, the basinโ€™s two biggest reservoirs โ€” Lake Powell and Lake Mead โ€” are now 70% empty. There is great concern that if the water level in Lake Powell drops below 3490โ€ฒ elevation (see graph below), it could become physically impossible to release sufficient water through the Grand Canyon to meet the water needs of ~30 million people downstream. In a worst case scenario, the volume of water flowing out of Glen Canyon Damย could intermittently shrink to a trickleย if the damโ€™s managers determine that continuous use of the lowest river outlets is too structurally risky and releases into the Grand Canyon must be drastically reduced. This calamity would further imperil unique freshwater ecosystems and wipe out the $50 million/year whitewater rafting industry in the Grand Canyon. We estimate that average annual water consumption needs to be reduced immediately by at least 13% below the recent 20-year average to rebalance water consumption with natural replenishment in this basin.

  • Great Salt Lake Basin:ย The lake has lost nearly half of its volume since 2000, dramatically shrinking the area of the lakeโ€™s surface and exposing extensive salt flats around the lakeโ€™s perimeter. Those salty soils are loaded with toxic heavy metals including arsenic, lead, and mercury. Recurring high winds blow that dangerous dust into the nostrils and lungs of more than two million people living in the Salt Lake City area. Brine shrimp living in the lake also suffer at low lake levels due to extreme salinity, greatly reducing the food supply for more than 10 million migratory birds along the Pacific Flyway and decimating production of brine shrimp eggs that are a critical feed source for the worldโ€™s aquaculture industry. The reduced evaporation from a shrinking lake also impacts the formation of storm clouds that drop the โ€œworldโ€™s greatest snowโ€ onto the Wasatch Mountains, site of the upcoming 2034 Winter Olympics. Water consumption in the basin needs to be rapidly reduced by 21% to stabilize the lake.

  • Rio Grande-Bravo:ย Reservoir storage in this large international basin is now three-quarters empty. New Mexicoโ€™s reservoirs hold only 13% of their capacity, presenting a โ€œDay Zeroโ€ scenario in which the remaining reservoir storage could be wiped out in just one or two more bad water years. This has created heated political conflict: New Mexico has been failing to deliver the volume of water it owes to Texas under the Rio Grande Compact, and Mexico has been unable to deliver sufficient water to the US under the terms of an international water treaty. Also of great concern is plundering of the vast groundwater reserves in the basin that has accelerated as surface water supplies have run short (see map of groundwater depletion below). Only half of the water being consumed for human endeavors in this basin is sustained by natural replenishment; the other half depends on unsustainably depleting reservoirs and groundwater aquifers and drying the river.

Governance Failures

The response to these crises has been woefully inadequate. Instead of addressing these imbalances at the scale and speed necessary to avert catastrophe, political leaders and water managers have been unable or unwilling to mobilize sufficient corrective actions to rebalance these water budgets. From my observations, there are multiple interacting causes of these governance failures:

  • There is continuing belief among many political leaders and water users that more bountiful replenishment years in the future will restore the massive accumulated deficits in reservoir and aquifer volumes. This belief runs contrary to the evidence of 25+ years of declining water trends and many scientific assessments warning that replenishment will continue to decline due to climate warming and aridification.
  • Water users have not been adequately or truthfully educated about the potential consequences of continued depletion of reservoirs and aquifers, and the rapid rate at which risks are increasing. The lack of honest communication and misunderstanding of pending dangers perpetuates complacency and inaction. What is needed is full and honest disclosure about the degree to which water consumption is out of balance with replenishment, and which water users and economic sectors are at great risk from deepening water shortages in future years.
  • Fearing hostile reaction to any mandated cutbacks in water consumption, political leaders lack the will to force or incentivize the actions required to rebalance consumption with (diminishing) replenishment.ย There are no plansย in the three basins described above for correcting imbalances at the necessary scale and speed. Legislative appropriations to address these crises have been orders of magnitude smaller than what is needed. These meager appropriations serve to placate the general public by giving the impression that responsible actions are being taken, serving as a smoke screen hiding the monstrous dangers on the horizon.
  • Instead of facing the reality that consumption needs to be speedily reduced, water managers continue to flout pipe dreams for augmenting water supplies such as long distance water importation schemes (bring water from the Great Lakes! bring water from the Yukon!), or desalinating ocean water, or recycling water โ€˜producedโ€™ from oil and gas fracking operations. There is no truthful reporting of how much additional water can be secured by these schemes, how much that water will cost, and who will be able to afford it. Irrigated agriculture is by far the dominant water consumer in the three basins we studied, but there is no way that farmers are going to be able to afford these water augmentation dreams.

The Way Forward: Sustainability Principles

Throughout my career Iโ€™ve always said that one should not deliver criticism without also offering solutions. In my Chasing Water book I outlined seven principles for sustainable water management.

Seven Principles

Credit: Sustainable Waters

I continue to believe in this recipe for water sustainability. But I need to offer some important clarifications:

  • Principle #1 is arguably the most important. Given that water consumed on farms is typically much greater than is consumed in cities, it is critically important to meaningfully engage farmers in water planning because they will bear the greatest burden of any limitations placed on water consumption. They can bring their best ideas forward, and in doing so help to ensure that water plans address both their concerns and their abilities to adapt. But it is essential that any water plans be built upon an honest and technically credible assessment of how much water will be available in the future.
  • Principles #2 and #3 should not be permanent, static volumes. Under a changing climate, the imposed limits need to be adaptive to changing water availability; during wet periods more water can be consumed, but lesser volumes should be allocated during dry times. I believe that the best way to do this is to set a 5-year fixed volume (a โ€œcapโ€œ) on annual consumption based on an average of how much water has been available in the recent 5 years, and then allocate portions or shares of that volume to each user (i.e., to each geopolitical unit, community, or individual water user). The cap volume needs to be updated every five years. I like a 5-year adaptive cap because it gives water users enough time to plan and implement changing allocations while not allowing any overconsumption to cause severe problems before readjusting the cap.
  • Principle #6 acknowledges the reality that water conservation measures can be costly for both rural and urban users, and can impact the profitability of farms. Subsidization of these expenses or losses will be essential in rebalancing these water systems for sustainability, enabling both urban and rural communities to transition to lower water use as rapidly as possible, and with least economic and social impact. The price tags may seem exorbitant or impossible at first blush, but the costs of continued unsustainable water use will be much, much greater.
  • Principle #7 requires investment in continuously monitoring reservoir, aquifer, and river levels, and enforcement of water allocations. One of the most important indicators of management performance is whether reservoir or aquifer levels or annual river flow volumes are declining. If this is the case, allocations need to be adjusted until balance returns.

Passing the Torch to a New Generation

Today is my retirement day.

In my Chasing Water book, I mused about the fact that when I was born in 1956, the western US was in the grips of one of the longest and most severe droughts in American history. It seems fitting to have spent my professional life focusing on water scarcity and environmental flows.

But I now find it quite depressing to acknowledge that our society has still not become any better at sustainable water management. Many river basins, including the three summarized above, are now facing their most dangerous crises.

When I was teaching water sustainability at the university level, I would point out to my students that in my birth year of 1956 virtually all of the Colorado Riverโ€™s water was being consumed. Why we allowed greater and greater use of water in that river basin for another half-century continues to astonish and bewilder me to this day. Why is our species so incapable of recognizing clear and present dangers and so inept at responding accordingly?

But I leave you eternally hopeful. The students that Iโ€™ve taught, and the many younger adults Iโ€™ve met through my work in more than 40 countries, have the intellect and the passion to bend the arc of water management back towards sustainability, if we give them the chance. I urge them to take up this charge, to find ways to gain positions of authority and power to lead toward better days ahead.

Iโ€™ll leave these next generations with one bit of advice: The management of water cannot remain solely in the hands of hydrologists and engineers and economists. We need legions of young new professionals that understand social science, political science, behavioral science. And we need artists.

After all, managing water is about people, and the human spirit.

10 Big Wins for Rivers in 2025: A snapshot of our biggest river successes from this past year — Hannah Axtell (AmericanRivers.org)

Rio Grande, Colorado | National Park Service

Click the link to read the article on the American Rivers website (Hannah Axtell):

December 19, 2025

Despite the escalating threats to rivers, this past year brought real progress worth celebrating. To highlight the positive strides being made across the country, weโ€™ve curated a list of 10 exciting wins for rivers, community safety, people, and wildlife. From proposed Wild and Scenic protections for nearly 100 miles of the Gallatin and Madison rivers, to major investments in river restoration and wildfire resilience in California, and stronger permit safeguards for the Rappahannock River, 2025 proved to be a year of meaningful breakthroughs for waterways nationwide. 

In no particular order, hereโ€™s a snapshot of 10 of our biggest river wins of 2025: 

  1. Secured major wins for Americaโ€™s Most Endangered Riversยฎ of 2025ย 

Our 2025 Americaโ€™s Most Endangered Riversยฎ report ranked the Tijuana River #2 due to toxic pollution threatening border communities. This designation, developed with partners Surfrider Foundation and Un Mar de Colores, helped catalyze swift federal action. Within three months of the April report release,โ€ฏAmerican Rivers and others were invited to meet with EPA Administrator Lee Zeldin in southern California, which helped build momentum for a landmark agreementbetween the United States and Mexico toโ€ฏaddress the ongoing public health crisis. This demonstrates how strategic advocacy, combined with persistent community leadership, drives solutions forโ€ฏrivers and their communities. 

The Rappahannock Riverโ€™sโ€ฏdesignation as one ofโ€ฏAmericaโ€™s Most Endangered Riversยฎ of 2025โ€ฏbrought crucial national attention to the threats facing Virginiaโ€™s longest free-flowing river. But this spotlight did more than raise awareness; it galvanized action that delivered tangible results. Working alongside our dedicated partners, The Friends of the Rappahannock, the Rappahannock Tribe, and the Southern Environmental Law Center, we achieved a significant victory for the river and the communities that depend on it. This collaborative effort secured permit changes for a proposed data center, banning industrial cooling withdrawals and reducing drought withdrawals by millions of gallons.

  1. Mobilized action to protect Public Lands and Roadless Areasย 

Bipartisan public outcry over a disastrous sell-off provision in a massive tax and spending bill led to the protection of public lands and the rivers that flow through them. Victory was snatched from the jaws of defeat thanks to supporters like you

The Trump administration is looking to rescind the Roadless Rule, which protects clean water and wildlife habitat by preventing road construction and timber harvest on roughly 45 million acres of national forests. This would be a significant setback (100,000 river miles) to our goal of protecting one million miles of rivers. Our team is making sure decision makers understand the impacts to clean drinking water supplies and we are mobilizing our supporters (weโ€™ve collected more than 10,000 signatures so far) in support of these important river protections.

  1. Safeguarding Montanaโ€™s Gallatin and Madison Riversย 

Rep. Ryan Zinke (MT) introduced the Greater Yellowstone Recreation Enhancement and Tourism Act (GYREAT Act) โ€“ Wild and Scenic legislation to protect nearly 100 miles of the Gallatin and Madison rivers and their tributaries in southwestern Montana. This legislation was developed through collaboration with American Rivers and our partners. If passed, these protections would create a vital corridor linking the rivers of Yellowstone National Park to the headwaters of the Missouri River.

  1. Defending healthy rivers and Tribal sovereigntyย 

American Rivers helped rally national, regional, and local partners in urging the Department of Transportation to protect aquatic connectivity programs โ€” efforts that restore fish passage, reconnect rivers and wetlands, and replace outdated culverts and road crossings. The joint comment letter was signed by 140 groups โ€” including Tribes, anglers, businesses, universities, research institutions, conservation organizations, community leaders, agencies, faith groups, and planners โ€” all united for healthier, more connected waterways. 

Additionally, when the Department of Energy urged the Federal Energy Regulatory Commission to roll back its 2024 policy protecting Tribal sovereignty in hydropower permitting, American Rivers acted fast. Working with Tribal attorneys, Native networks, and partner organizations, we mobilized national opposition and filed formal comments โ€” demonstrating our deep commitment to Tribal leadership and ensuring healthy rivers. Weโ€™ll continue working alongside Tribal partners to ensure these protections remain strong.

  1. Restoring mountain meadows in Californiaย 

American Rivers is a key member of The Sierra Meadows Partnership, a coalition of environmental organizations working together to restore 30,000 acres of mountain meadows by 2030. These meadows act as natural sponges that store water, improve drought resilience, and provide essential wildlife habitat. Through this collaborative effort, we successfully secured a $24.7 million block grant from the Wildlife Conservation Board to support our restoration work.

  1. Advanced critical protections for New Mexicoโ€™s waterwaysย 

After naming New Mexicoโ€™s waterways #1 on Americaโ€™s Most Endangered Riversยฎ of 2024 list, weโ€™re celebrating significant wins across the state. In the Pecos watershed โ€” home to elk, black bears, Rio Grande cutthroat trout, and generations-old acequia farms โ€” the Department of Interior paused new mining claims across 165,000 acres while pursuing longer-term protections. Through advocacy with our partners, we helped secure Outstanding National Resource Waters protection for over 250 miles of rivers across five watersheds, including the Rio Grande. And now, Senator Heinrich (NM) and the All Pueblo Council of Governors are championing protection of the Caja del Rio โ€” a 107,000-acre landscape along the Rio Grande and Santa Fe rivers that holds deep cultural significance for Puebloan and Hispanic communities while supporting diverse wildlife.

  1. Furthering community safety through dam awarenessย 

American Rivers spoke on panels and hosted webinars addressing the deadly threat of low head dams, generating hundreds of participants from across the dam removal and safety industries. A low head dam is a human-made structure that spans the full width of a river and is designed to allow water to continuously flow over it, creating a dangerous hydraulic and earning them the nickname โ€œdrowning machines.โ€ Our educational workshops brought together leading experts to discuss solutions for addressing these public safety hazards while advancing river restoration solutions.

  1. Building momentum for dam removal across the Northeastย 

American Rivers is celebrating a wave of funding that will free multiple rivers across the Northeast. We were awarded $220,000 to remove the Yopp Pond dam on the Fourmile River in Connecticut โ€” the first barrier blocking this coastal river that drains to Long Island Sound. Fisheries biologists note this removal will be transformational for alewife runs in this critical watershed. Additionally, New Hampshire Fish and Game committed $150,000 to support two strategic dam removals: North Branch Gale dam in the Upper Connecticut River watershed and Mead Brook dam in the Contoocook River watershed. Both dams impact excellent cold-water habitat and are scheduled for removal in 2026. Additionally, the Davis Conservation Foundation granted $20,000 for our hydropower relicensing work in Maine.

  1. Defended Idahoโ€™s Salmon Riverย 

Along with our partners at Advocates for the West and coalition members in Idaho, American Rivers and our Action Fund filed a lawsuit against the Forest Service to prevent a massive open-pit gold mine at the headwaters of the South Fork Salmon River. This important waterway is a national treasure that provides critical spawning habitat for the longest-distance, high-elevation salmon migration on Earth, as well as world-class whitewater recreation and fishing. It has been listed as one of Americaโ€™s Most Endangered Riversยฎ for three consecutive years.

  1. ย Improved wildfire resilience in Californiaย 

American Rivers and our partner, Terra Fuego Resources Foundation, completed prescribed fire burns on 160 acres as part of a 570-acre fuel reduction and prescribed fire project โ€” a critical effort to protect the South Yuba River and the communities of Nevada City and Grass Valley from catastrophic wildfire. In a major boost for river restoration, the California Wildlife Conservation Board approved nearly $5 million to launch the Pickel Meadow Restoration Project on the West Walker River. Construction begins this summer, marking an exciting next chapter for this important watershed.

December 29, 2025

The Colorado River Water Users Association annual conference met in Las Vegas [December 16-18, 2025]. Each year, over a thousand government officials, members of the press, municipal water district leaders, water engineers, ranchers, and tribal members meet to discuss the management of the mighty Colorado River. Hanging over the three-day conference was a stalemate between the upper and lower basin states over how to manage the Colorado River after current operational guidelines expire at the end of 2026.

Throughout the conference, the statesโ€™ inability to reach a consensus deal produced ripple effects. The stalemate held back progress on both near term shortage concerns (experts predict that Lake Powell will be only 28% full at the end of the โ€™25-โ€™26 water year) and long-range planning, such as the development of the next โ€œMinuteโ€ agreement between the United States and Mexico.

The closing act of CRWUA 2025 was an orderly (and familiar) report from each of the basin statesโ€™ principal negotiators that their state is stretched thin but remains committed to finding a consensus agreement. This final session had no discussion or Q&A. The basin states now have until February 14th to provide the Bureau of Reclamation with their consensus deal, which would presumably be added to an Environmental Impact Statement (EIS) draft that is expected to be released in early January. With time running short, many worry that public participation in the EIS process โ€“ vital to informed decision-making โ€“ will be greatly reduced.

Still, as Rhett Larson of Arizona State University said on the first day of the conference, โ€œDesert rivers bring people together.โ€ Tribal governments continue to innovate in the areas of conservation and storage, even in spite of ongoing challenges to meaningful access of federally reserved tribal water rights. For instance, the Colorado River Indian Tribes, or CRIT, shared news of a Resolution and Water Code recently passed by their Tribal Council which work together to recognize the Colorado Riverโ€™s personhood under Tribal law. This provides CRIT with a holistic framework for on-reservation use and requires the consideration of the living nature of the Colorado River in off-reservation water leasing decisions. John Bezdek, who represented CRIT at the conference, put it this way: โ€œIf laws are an expression of values, then this tribal council is expressing to the world the importance of protecting and preserving the lifeblood of the Colorado River.โ€ Among others, Celene Hawkins of The Nature Conservancy and Kate Ryan of the Colorado Water Trust also shared about the unique, and often unlikely, partnerships formed to protect stream flows and the riparian environment across the Colorado River basin.

Notwithstanding the basin statesโ€™ current deadlock, one theme rang true at CRWUA 2025: Despite the dire hydrologic and administrative realities facing decision-makers today, the Colorado River continues to bring unlikely parties together.

December 19, 2025

The single most important gathering of Colorado River Basin officials came and went โ€” with no significant announcements regarding the often frustrating yet crucial seven-state negotiations for how to divvy up the river over the next 20 years…Here are three takeaways as the states wrestle with basinwide overuse of water, declining river flows due to a warming world and how to meet the federal governmentโ€™s Valentineโ€™s Day deadline for a consensus-based deal.

States far from deal โ€” with less than 60 days left

Unlike last yearโ€™s conference, the seven states agreed to sit on a panel that was added to the agenda for the last day. The ballroom was still packed for the early morning session. Thatโ€™s because the stakes are high for states to meet Burgumโ€™s Feb. 14 deadline for a seven-state agreement. Should they not deliver one, Burgum could intervene and states are likely to sue. The Lower Basin states have agreed to shoulder the brunt of a massive deficit the system faces that totals 1.5 million acre-feet, or almost 489 billion gallons. However, the Upper Basin states of Colorado, Utah, New Mexico and Wyoming say they donโ€™t have more water to give should cuts in their jurisdictions become necessary. Conflicts exist with state laws, too…

Temporary deal could be on the table to avoid courtroom

Nevadaโ€™s governor-appointed negotiator, John Entsminger, spoke last on the panel and called out the other six states for failing to cede any ground on further conservation in their remarks. Without some compromise from each state on these long-standing arguments, the negotiations are โ€œgoing nowhere,โ€ he said. While the states have been expected up until this point to deliver a 20-year deal, Entsminger suggested on the panel that a temporary, five-year deal could be on the table to comply with the Feb. 14 deadline.

Poor outlook sending shockwaves throughout basin

The underlying issues of the Colorado River are making this moment much more precarious. Several experts presented a dismal picture for the system at large. Carly Jerla, senior water resource program manager at the Bureau of Reclamation, said the agencyโ€™s most recent projections place flows into Lake Powell anywhere between 44 percent to 73 percent of average this upcoming year. And since 2006, that replenishment of the reservoir has declined about 15 percent because of poor snow years, evaporative losses and more…

Here the water level is above dead pool, meaning water can be released via the river outlets, but it is below minimum power pool, so water cannot yet enter the penstocks to generate electricity.

Jack Schmidt, who leads the Center for Colorado River Studies at Utah State University, has published several papers this year alongside a group of experts throughout the basin. By his estimation, should snowpack in the Rocky Mountains fail to impress again this winter, water managers may be blowing through a crucial buffer that ensures water can be released from Lake Powell into Lake Mead โ€” and that hydropower generation can continue.

December 16, 2025

A new report from Colorado Lawโ€™s Colorado River Research Group warns the Colorado River Basin is โ€œout of time,โ€ describing conditions so severe they threaten the regionโ€™s water supply, economy and governance. Called โ€œColorado River Insights 2025: Dancing with Deadpool,โ€ theย reportย details a dire assessment of the basinโ€™s worsening crisis and offers options for reform. According to the report, reservoirs that once stored four years of river flows are now more than two-thirds empty. The authors note a single dry year or two could push Lake Powell and Lake Mead below critical thresholds, jeopardizing hydropower, water deliveries, and even physical conveyance downstream. The report concludes that current operating rules through 2026 are unlikely to prevent this scenario.ย 

โ€œThis report underscores that the basin is out of time, the crisis is no longer theoretical,โ€ said Douglas Kenney, director of the Western Water Policy Program of the Getches-Wilkinson Center at the University of Colorado Law School and chair of the Colorado River Research Group.

โ€œPost-2026 negotiations must produce durable, equitable, climate-realistic solutions โ€” and they must do so urgently. The message is stark: the Colorado River system is now dancing with Deadpool.โ€

Among the key challenges:

  • Severe shortage risk: The authors warn that if the next two winters are dry, combined usable storage in Powell and Mead could fall below 4 million acre-feet โ€” far short of whatโ€™s needed for water supply and compact obligations.
  • Climate-driven decline: Rising temperatures, shrinking snowpack efficiency and ocean-atmosphere interactions are reducing runoff and precipitation.ย 
  • Safety nets collapsing: Groundwater reserves are rapidly depleting, while federal capacity โ€” funding, staffing and science programs โ€” are eroding. Interstate cooperation is fraying, and litigation may be on the table.

Authors stress that many challenges are self-inflicted and, in their view, solvable with technical, legal and financial tools already available.

The big reservoirs Mead and Powell remain perilously low and the seven states that share the basin have been unable to agree on cuts that would reduce their reliance on the shrinking river.

Reservoir operating rules expire at the end of 2026. If no agreement is reached the federal government could step in, or the states could take their chances in court. Itโ€™s a risky move that no one in principle seems to want. Yet brinkmanship and entrenched positions have stymied compromise.

The basinโ€™s Indian tribes, which collectively have rights to more than a quarter of its recent average annual flow, are adamant that their interests โ€“ and more broadly, the river itself โ€“ be protected. โ€œAny progress made in the negotiations to date is merely rationing a reduced supply, not actively managing and augmenting it as a shared resource with strategies and tools that can benefit the entire basin,โ€ the leaders of the Gila River Indian Community wrote on November 12.

The Colorado River Indian Tribes, whose riverside reservation includes lands in Arizona and California, voted in November to extend legal personhood to the river under tribal law.

National Park Sites Along #ColoradoRiver Grappling With Declining Water — National Parks Traveler #COriver #aridification

National Park Service officials at Lake Powell (above) and Lake Mead are grappling with declining Colorado River levels/NPS file.

December 23, 2025

At Lake Mead National Recreation Area in Nevada, “the National Park Service’s focus remains on sustaining boating access and visitor services across the park, including operations at Hemenway Harbor, Callville Bay Marina, Echo Bay, Temple Bar Marina, and South Cove to the extent feasible,” the National Parks Traveler was told.

“As part of that effort, construction began at Hemenway Harbor last summer to extend the launch ramp and help maintain access as conditions change. Lake levels are closely monitored, and NPS operations continue to be adjusted as needed to support safe recreation while protecting park resources,” the Park Service said.

Two years ago Lake Mead officials adopted a plan to “maintain recreational motorboat access in the event water declines to 950 feet.” As of Tuesday, the elevation wasย 1061.76 feet, according to the U.S. Bureau of Reclamation. Atย Glen Canyon National Recreation Area, which straddles the Utah-Arizona border, the Park Service hasย spent more than $100 millionย in recent years to extend boat ramps and relocate a takeout for river runners coming down the Colorado River throughย Canyonlands National Park.

“The public is encouraged to make informed decisions before they plan their visit to Lake Powell by viewing lake level data on the Bureau of Reclamation website at 40-Day Data | Water Operations | UC Region | Bureau of Reclamation and projected reservoir levels at 24-Month Study | Upper Colorado Basin | Bureau of Reclamation,” the Park Servicxe said.

December 25, 2025

Western states that rely on the Colorado River have less than two months to agree on how to manage the troubled river โ€“ and pressure is mounting as the federal government pushes for a compromise and a troubling forecast for the riverโ€™s two biggest reservoirs looms.

Top water officials for the seven Colorado River Basin states โ€” Arizona, California, Nevada, Colorado, New Mexico, Utah, and Wyoming โ€” gathered for the three-day Colorado River Water Users Association conference at Caesars Palace in Las Vegas last week.

Colorado River states have until Feb. 14 to reach a new water sharing agreement before current operating rules expire at the end of 2026 โ€”or the federal government will step in with their own plan.

Despite the fast-approaching deadline, states reiterated many of the same issues they did during previous years at the conference, namely, which water users will need to sacrifice more water to keep the Colorado River stable as overallocation, climate change, and rising demand sucks the river dry.

Nevadaโ€™s chief river negotiator and general manager of the Southern Nevada Water Authority John Entsminger offered a succinct but sharp assessment of the negotiations during a panel discussion Thursday.

โ€œIf you distill down what my six partners just said, I believe thereโ€™s three common things: Hereโ€™s all the great things my state has done. Hereโ€™s how hard/impossible it is to do any more. And here are all the reasons why other people should have to do more,โ€ Entsminger said.

โ€œAs long as we keep polishing those arguments and repeating them to each other, we are going nowhere,โ€ he continued.

The seven states that share the riverโ€™s flows have been deadlocked for nearly two years over how to govern the waterway through the coming decades โ€” even as water levels at Lake Mead and Lake Powell are forecasted to reach record lows after two straight years of disappointing snowpack across the West.

The Colorado Riverโ€™s headwaters saw a weak snowpack last winter, contributing to one of the worst spring runoff seasons on record. Water flow into the river this year was only 56% of average, leading to significant reductions in Lake Powell, according to the Interior Departmentโ€™s Bureau of Reclamation.

Federal officials also released a troubling forecast of expected flows for the river in 2026, which were significantly lower than previous predictions. Projections from the Bureau of Reclamation found the Colorado Riverโ€™s inflow next year would likely be 27% lower than normal, with worst-case scenarios predicting even lower flows.

Without a strong winter snow season, itโ€™s possible Lake Powellโ€™s levels could drop low enough to cease hydropower production by next October โ€” a scenario that would also limit the departmentโ€™s ability to send water downstream to Arizona, California and Nevada.

The federal government has refrained from imposing its own plan for the river, preferring the seven basin states reach consensus themselves. But the Interior Department has ramped up pressure on states to reach a deal.

The Bureau of Reclamationโ€™s Acting Commissioner Scott Cameron said he and other federal officials have intensified efforts to bring states to a consensus, flying out West every other week since early April to meet with the seven statesโ€™ river negotiators.

โ€œThe expiration of the current agreements is not a distant horizon. Itโ€™s less than a year away. The time to act is now,โ€ said Cameron.

Within the next few weeks, the Bureau of Reclamation will release a range of proposals to replace the riverโ€™s current operating rules, but said they would not identify which set of operating guidelines the federal government would prefer

During the conference, negotiators for the seven states repeated that they are still committed to finding a consensus despite missing previous deadlines. Californiaโ€™s biggest water districts said they were willing to โ€œset aside many of their legal positionsโ€ in order to reach a seven-state agreement.

However, a long-term multidecade strategy for managing low river flows is likely out of reach.

โ€œI went into this processโ€ฆadvocating strenuously for a 20- to 30-year deal,โ€ said Entsminger. โ€œI no longer believe thatโ€™s possible with the time we have left and with the hydrology that weโ€™re facing.โ€

Entsminger said the โ€œbest possible outcome at this junctureโ€ is a short-term five-year deal that sets new rules around water releases and storage at Lakes Powell and Mead.

During a panel of state negotiators, states highlighted water conservation efforts they have undertaken to reduce water use and protect the river, but all explained why their state canโ€™t take on more cuts.

โ€œOur savings accounts are totally depleted,โ€ said Utahโ€™sโ€™s river negotiator, Gene Shawcroft. โ€œReserviours were full when we started this process. Theyโ€™re empty now.โ€

One of the biggest disagreements between the Upper and Lower Basin states is over which faction should have to cut back on their water use during dry years.

The Lower Basin โ€“ Nevada, Arizona, and California โ€“ have agreed to take the first 1.5 million acre-feet in water cuts needed to address deficits and evaporation that are reducing flows in the river, but say any additional cuts during dry years must be shared with upstream states. Under the current agreement, Lower Basin states must take mandetory cuts when water levels in Lakes Powell and Mead are low.

The Upper Basin, which is not subject to mandatory cuts under the current guidelines, say they already use much less water than downstream states and should not face additional cuts during shortages.

Any more cuts to water users in downstream states during dry years will be politically perilous, explained Arizonaโ€™s top negotiator, Tom Buschatzke. Arizona requires the state legislature to approve any changes to Colorado River management rules impacting the state.

Buschatzke called for the Upper Basin โ€“ Colorado, Wyoming, New Mexico, and Utah โ€“ to split any additional water cuts with the Lower Basin states 50-50.

โ€œWe need conservation in the Upper Basin that is verifiable and mandatory,โ€ Buschatzke said, during the panel.

โ€œI have to go to my legislature and get that approval,โ€ he continued. โ€œAnd I will say right now, I do not think there is anything on the table from the Upper Basin that would compel me to do that today.โ€

New Mexicoโ€™s river negotiator, Estevan Lรณpez, responded, โ€œI think weโ€™ve been pretty clear. We are unwilling to require additional mandatory reductions on our water users.โ€

December 17, 2025

Federal officials have released a โ€œsoberingโ€ forecast of 2026 water levels in the Colorado River, with expected flows plummeting from previous predictions. Precipitation later in the winter could turn those dire forecasts around, officials say, but the current outlook is grim for a river already flirting with crisis.  Officials published the new forecast on Monday, only a day before negotiators and stakeholders from the riverโ€™s basin states gathered in Las Vegas for a three-day conference. The federal government has given states until February to agree on a longer-term strategy for managing low river flows. The Colorado Riverโ€™s flow in 2026 (specifically, the unregulated inflow to Lake Powell) could be 27% lower than normal, according to the most probable scenario in the December forecast, with worst-case scenarios predicting even lower flows. The projection has worsened estimates released in November (16% lower than normal in most probable scenarios).

โ€œWe all know Mother Nature is a trickster and can often confound our expectations. We certainly hope she intends to do that this year,โ€ said Wayne Pullan, the Bureau of Reclamationโ€™s regional director for the Upper Colorado River Basin, on Tuesday. โ€œBut Decemberโ€™s outlook is troubling.โ€

The bureau, which manages federal dams, will delay water releases at Lake Powell to conserve supplies in the reservoir during the dry winter months in 2026, Pullan said. Even with those efforts, however, the lakeโ€™s water levels could fall to critical levels in 2027 as another disappointing year hits the basin. A bad water year in 2026 would compound already poor conditions from 2025, when river flows have been less than half of normal. The new forecast increases the possibility that water levels in Lake Powell could drop below the intakes for hydropower turbines and that releases from the lake could fall below the annual average required to meet the requirements of the 1922 Colorado River Compact, which governs water allocation between the seven states that use the river. Without above-average flows in future years to bring averages back up, or an interstate deal on how to manage drought, those low releases could set the stage for a legal battle on the river.

The Rundown

  • Colorado Riverย states have been given less than two months to agree on how to share water cuts from the shrinking river.
  • Homeland Securityย waives environmental lawsย to speed the construction of a border wall in parts of New Mexico.
  • A federal judge proclaims federal authority over the contentiousย Line 5 oil pipelineย that crosses the Great Lakes.
  • U.S., Mexican governments signย Tijuana Riverย sewage cleanup agreement.
  • The House passes a bill to changeย environmental reviewsย for infrastructure permitting.
  • USGS study finds lower water levels in Coloradoโ€™s Blue Mesa reservoir the cause of increasedย toxic algal blooms.

And lastly, a draft EIS for post-2026 Colorado River reservoir operations, when current rules expire, will be published in the coming weeks.

โ€œLet me be clear, cooperation is better than litigation. Litigation consumes time, resources, and relationships. It also increases uncertainty and delays progress. The only certainty around litigation in the Colorado River basin is a bunch of water lawyers are going to be able to put their children and grandchildren through graduate school. There are much better ways to spend several hundred million dollars.โ€ โ€“ Scott Cameron, acting commissioner of the Bureau of Reclamation, speaking at the Colorado River Water Users Association conference on December 17, 2025. Cameron encouraged the states to reach an agreement on water cuts and reservoir operating rules instead of suing each other.

By the Numbers

February 14: New Interior Department deadline for the seven Colorado River states to reach an agreement on water cuts and reservoir operations. If the states fail at that, Interior could assert its own authority. There could also be lawsuits. A short-term agreement might be necessary.

The deadline, according to Interiorโ€™s Andrea Travnicek, is for several reasons. It gives states time to pass legislation, if necessary. It provides time for consultation with Mexico and the basinโ€™s tribes. And it allows for reservoir operating decisions in 2027 to be set this fall.

โ€œTime is of the essence, and it is time to be able to adjust those stakes, to arrange so compromises can be made,โ€ Travnicek said.

Line 5 Oil Pipeline Court Case
A U.S. district judge ruled that the federal government, not the state of Michigan, has authority over the contentious Line 5 oil pipeline that crosses the Great Lakes at the Straits of Mackinac.

Michiganโ€™s top officials have attempted to shut down Enbridge Energyโ€™s Line 5 since 2020 when Gov. Gretchen Witmer revoked the companyโ€™s easement.

In his ruling, Judge Robert Jonker determined that the federal Pipeline Safety Act gives the U.S. government the sole authority over Line 5โ€™s continued operation, the Associated Press reports.

U.S. and Mexican representatives signed an agreement that will facilitate the cleanup of chronic sewage pollution in the Tijuana River, a shared waterway.

Called Minute 333, the agreement outlines actions and sets timelines. A joint work group will assess project engineering and feasibility studies. Mexico will build a wastewater treatment plant by December 2028 and a sediment control basin by winter 2026-27. The agreement also addresses monitoring, planning, and data sharing.

Permitting and Land Use Bills
House Republicans used the week before the holiday break to pass a bill that changes infrastructure permitting processes.

The SPEED Act, which passed with support from 11 Democrats, changes the National Environmental Policy Act and the environmental reviews it requires for major federal projects. It restricts reviews to immediate project impacts, sets timelines, and limits lawsuits.

The best solution might be keeping the reservoir high enough, the report says. That will not be easy in a drying and warming region with competing water demands.

On the Radar

Colorado River Draft EIS Coming Soon
In the coming weeks โ€“ in early January if not by the end of the year โ€“ the Bureau of Reclamation will publish a draft environmental impact statement for changes to how the big Colorado River reservoirs will be managed.

Reclamation began its environmental review about two and a half years ago. The agency had hoped to slot a seven-state consensus agreement into the document. But since there is no agreement, the document will instead describe a โ€œbroad rangeโ€ of options, said Carly Jerla of Reclamation, who spoke at the Colorado River Water Users Association conference.

The draft will not select a preferred option, Jerla said. Instead that will come in the final version.

โ€œWeโ€™ve set up a draft EIS that reflects a range of carefully crafted alternatives to enable the further innovation and the ability of the basin to come to a consensus agreement to be able to adopt in time for the 2027 operations,โ€ Jerla said.

December 18, 2025

The seven states that rely on theย Colorado Riverย to supply farms and cities across the U.S. West appear no closer to reaching a consensus on a long-term plan for sharing the dwindling resource. The riverโ€™s future was the center of discussions this week at the annual Colorado River Water Users Association conference in Las Vegas, where water leaders from California, Nevada,ย Arizona, Colorado, New Mexico, Utah and Wyoming gathered alongside federal and tribal officials. It comes after the states blew past a November deadline for a new plan to deal with drought and water shortages after 2026, when current guidelines expire. Theย U.S. Bureau of Reclamationย has set a new deadline of Feb. 14.ย  Nevadaโ€™s lead negotiator said it is unlikely the states will reach agreement that quickly.ย 

โ€œAs we sit here mid-December with a looming February deadline, I donโ€™t see any clear path to a long-term deal, but I do see a path to the possibility of a shorter-term deal to keep us out of court,โ€ John Entsminger of the Southern Nevada Water Authority told The Associated Press.

The federal government continues to refrain from coming up with its own solution โ€” preferring the seven basin states reach consensus themselves. If they donโ€™t, a federally imposed plan could leave parties unhappy and result in costly, lengthy litigation. Not only is this water fight between the upper and lower basins, individual municipalities, tribal nations and water agencies have their own stakes in this battle. California, which has the largest share of Colorado River water, has over 200 water agencies alone, each with their own customers.

โ€œItโ€™s a rabbit hole you can dive down in, and it is incredibly complex,โ€ said Noah Garrison, a water researcher at the University of California, Los Angeles.

Lower Basin states pitched a reduction of 1.5 million acre-feet per year to cover a structural deficit that occurs when water evaporates or is absorbed into the ground as it flows downstream. An acre-foot is enough water to supply two to three households a year. But they want to see a similar contribution from the Upper Basin. The Upper Basin states, however, donโ€™t think they should have to make additional cuts because they already donโ€™t use their full share of the water and are legally obligated to send a certain amount of water downstream.

โ€œOur water users feel that pain,โ€ said Estevan Lรณpez, New Mexicoโ€™s representative for the Upper Colorado River Commission.

December 18, 2025

Federal water officials addressed the increasingly grim river conditions and laid out their options for dealing with plummeting reservoir levels over the first two days of the largest annual gathering of water managers in the Colorado River Basin.

On Monday, the U.S. Bureau of Reclamation released its monthly report, which projects a two-year hydrology outlook for the operation of the nationโ€™s two largest reservoirs: Lake Powell and Lake Mead. The report provided a sobering backdrop to the Colorado River Water Users Association conference at Caesarโ€™s Palace in Las Vegas.

Westwide SNOTEL basin-filled map December 18, 2025. via the NRCS.

With the slow start to winter in the Upper Basin (Colorado, New Mexico, Utah and Wyoming), the report showed a drop in Lake Powellโ€™s projected 2026 inflow of 1 million acre-feet since the November forecast. Under the โ€œminimumโ€ possible inflow, Lake Powell would fall below the surface-elevation level of 3,490 feet needed to generate hydropower by October 2026 and stay there until spring runoff briefly bumps up reservoir levels in summer 2027; but the water level would again dip below 3,490 in the fall of 2027. 

Under the โ€œmost probableโ€ forecast, the reservoirโ€™s level stays above minimum power pool, but falls below the target elevation of 3,525 until the 2027 runoff. (Reservoir levels below the target elevation trigger more drastic emergency actions.)  The reservoir is currently about 28% full, down from 37% at this time last year.

Wayne Pullan, regional director for the bureauโ€™s Upper Basin, called the December projections troubling.

โ€œThat outlook is sobering for all of us,โ€ Pullan said at Tuesdayโ€™s meeting of the Upper Colorado River Commission. 

Snowpack, which is lagging across the Upper Basin, hovered at around 61% of median Wednesday. Snowpack in the headwaters of the Colorado River was 53% of median.

The Colorado River basin has been locked in the grip of a megadrought since the turn of the century. Climate change and relentless demand have fueled shortages, pushed reservoirs to all-time lows and sent water managers scrambling. 

Pullan laid out four tools that the Bureau of Reclamation can use to respond to the projected low water levels to prevent the surface of Lake Powell at the Glen Canyon Dam from falling below 3,500 feet in elevation.

The first tool is shifting some winter releases to the summer months when runoff into the reservoir will compensate for those releases. The second is releasing water from upstream reservoirs to boost Lake Powell. The third is reducing releases when water levels hit a certain trigger elevation. 

Representatives from the Upper Basin and Lower Basin (Arizona, California and Nevada), which share the river, have been in talks for two years โ€” with long periods of being deadlocked in disagreement โ€” about how to manage the river after the current guidelines expire at the end of 2026. The 2007 guidelines set annual Lake Powell and Lake Mead releases based on reservoir levels and did not go far enough to prevent them from being drawn down during consecutive dry years.

โ€œWe have learned that if we failed at all in these last 25 years, it might have been that our vision wasnโ€™t sufficiently pessimistic,โ€ Pullan said.

Statesโ€™ representatives have said they are still committed to finding a consensus after they blew past a Nov. 11 deadline to come up with an outline of a plan. Federal officials have set a second deadline of Feb. 14 for the states to submit a detailed plan. 

While water managers across the basin wait for an agreement from the states, federal officials are moving ahead with the National Environmental Protection Act review process and crafting an environmental impact statement for future reservoir operations. Reclamation officials said that they plan to release a draft EIS around the end of the year and that the alternatives analyzed in the EIS will be broad enough that they would capture any seven-state agreement. The draft EIS will not choose a preferred alternative.

โ€œProbably all of you have heard us say, ad nauseum, this emphasis on creating a broad range of alternatives,โ€ Carly Jerla, a senior water resource program manager at the Bureau of Reclamation, said Wednesday. โ€œWe really went about this by taking input over the last almost two years from you all โ€ฆ to craft a broad range that really reflects the ideas on how to operate the system.โ€

Not a routine water source

This isnโ€™t the first time the basin has experienced dire straits. In 2021, as Lake Powell flirted with falling below minimum power pool, the Bureau of Reclamation made 181,000 acre-feet in emergency releases from three Upper Basin reservoirs โ€” Flaming Gorge, Navajo and Blue Mesa โ€” to protect critical Lake Powell elevations. 

These reservoirs are part of the Colorado River Storage Project, and their primary purpose is to control the flows of the Colorado River. But the unilateral action by the feds rubbed Upper Basin water managers the wrong way. The 36,000 acre-feet released from Blue Mesa cut short the boating season on Coloradoโ€™s largest reservoir, which is on the Gunnison River.

On Tuesday, Coloradoโ€™s representative, Becky Mitchell, said Upper Basin reservoirs are not a routine water source for the Lower Basin.

โ€œI appreciate as weโ€™re in critical and dire situations how we use our resources to protect our infrastructure, but we have to shift,โ€ Mitchell said. โ€œOur biggest resource is post-2026 and figuring out how do we do this in a way that doesnโ€™t create those to be routine water sources.โ€

So far, the basin has avoided the worst outcomes by getting last-minute reprieves in the form of wet years in 2019 and 2023. But overall, Jerla said, the Colorado River can expect to see persistent dry years and challenging conditions in the future, and water managers will need more adaptive, flexible solutions. 

โ€œ(This is) really our last year together operating under the existing agreements, kind of stretching the flexibilities and the bounds and stability which those agreements provide,โ€ she said.

December 19, 2025

At the Colorado River Water Users Association annual conference in Las Vegas, Colorado River Basin states remain at an impasse over how to cut their water use as Lake Mead and Lake Powell verge on record lows.

The Colorado River Basin is, quite literally, 50 feet away from collapse, and an agreement to save it is nowhere in sight. 

Water titans clashed at Caesars Palace in Las Vegas this week, where negotiators from each of the seven Colorado River Basin states outlined what they have done to protect the riverโ€”and pointed fingers at each other, demanding more.

Talks over how to manage the river after 2026, when current drought mitigation guidelines expire, began two years ago. Federal deadlines have come and gone, and the stakes are higher than ever as climate change and overuse continue to push the river that 40 million people rely on to the edge. Still, the states are refusing to budge. 

โ€œItโ€™s now 2025, weโ€™re here in a different hotel a couple years later and the same problems are on the table. In the last two years, weโ€™ve been spinning our wheels,โ€ said JB Hamby, Californiaโ€™s lead negotiator, at the annual Colorado River Water Users Association conference.โ€œTime has been wasted, and like water, thatโ€™s a very precious resource.โ€

The Colorado River flows from Wyoming to Mexico, supplying water to seven U.S. states, two Mexican states and 30 tribes. But the bedrock law guiding its management, the 1922 Colorado River Compact, overestimated how much water the river could provide, leading to state allocations that promised more than was ultimately available. The nationโ€™s two largest reservoirs, lakes Mead and Powell, which for decades have met the excess demand driven by overly optimistic allocations, are at the brink. Lake Mead is 33 percent full; Powell is just 28 percent full. If the latterโ€™s water levels drop by an additional 50 feet, the water behind Glen Canyon Dam would be trapped, limiting deliveries to California, Arizona and Nevada, and preventing the dam from generating hydropower.ย 

The federal governmentโ€™s data indicate that Lake Powell could drop to that level, known as โ€œdeadpool,โ€ by the summer of 2027 if significant cuts arenโ€™t made.

Yet, the states remain stuck on the same points that, for years, have prevented any of them from agreeing to reduce their long-term use enough to prevent the collapse of the Colorado River system.

The structural deficit refers to the consumption by Lower Basin states of more water than enters Lake Mead each year. The deficit, which includes losses from evaporation, is estimated at 1.2 million acre-feet a year. (Image: Central Arizona Project circa 2019)

In aย proposalย to the federal government from March 2024, Arizona, California and Nevada, the three states that make up the Lower Basin, which uses the greatest amount of the riverโ€™s water and has historically over-consumed its allotments, put annual cuts of 1.5 million acre feet of water on the table for a post-2026 agreement. [ed. This includes 1.2 MAF for the “Structural Deficit”. The Lower Basin has never been charged for shrink in Lake Mead and in the Colorado River mainstream. USBR said earlier in the Post-2026 guideline negotiations that the LB would have to be charged for shrink going forward.] They want to see any necessary reductions after that, which experts estimate could range from anotherย 2 to 4ย million acre-feet per year, divided among all seven states. One acre-foot of water is enough to supply somewhere between two and four households for a year.

The Upper Basin states of Colorado, New Mexico, Utah and Wyoming have proposed taking voluntary reductions. They argue they should not face mandatory cuts because the Upper Basin has never used the full amount of water it was allocated under the 1922 compact, which apportions 7.5 million acre-feet to each basin. Due to climate change and a lack of storage infrastructure, they say theyโ€™re already living with cuts while delivering the required water to the Lower Basin. 

In closing comments on Thursday, which provided a rare opportunity for the public to hear what have otherwise been behind-closed-doors conversations, negotiators expressed frustration, rehashing the same talking points they have used for years.

โ€œAs long as we keep polishing those arguments and repeating them to each other, we are going nowhere,โ€ said John Entsminger, Southern Nevada Water Authorityโ€™s general manager, and that stateโ€™s negotiator. He added that at this point, the best he could envision was an interim five-year operating plan agreement, not the multi-decadal deal that would be necessary to bring certainty to the region. Even a short-term deal still requires resolving debates about what each state can commit to. 

The impasse heightens the risk that the federal government will have to step in to implement a plan to protect its infrastructure. Many fear that a failure to reach state consensus could lead to exorbitantly expensive litigation, delay needed action for years and cause uncertainty throughout the region.

The federal Bureau of Reclamation has told the basins to develop a plan by Feb. 14, 2026, after the states blew past a previous Nov. 11 deadline, so it can include their agreement in the federal governmentโ€™s environmental analysis of a post-2026 plan to operate Lakes Mead and Powell and oversee their dam releases.

Lorelei Cloud, chair of the Colorado Water Conservation Board and co-founder of the Indigenous Womenโ€™s Leadership Network, cautioned against federal intervention. The federal government has fallen short of its trust responsibility to the tribes by failing to provide water, she said. 

โ€All the people on the ground really need to step up and provide a solution,โ€ she said.

Bill Hasencamp, manager of Colorado River Resources for the Metropolitan Water District of Southern California, said that federal intervention would mean reverting to pre-2007 operating guidelines under which water allocations are determined annually. That would make it harder for Metropolitan, which serves 19 million people across Southern California, to plan for the future.

โ€œWe might invest in sources that we donโ€™t need, but also we may have to restrict water deliveries from time to time, as weโ€™ve done in the past,โ€ said Hasencamp. โ€œFor us, thatโ€™s a fail.โ€

But Tom Buschatzke, the director of the Arizona Department of Water Resources and the stateโ€™s lead negotiator, told Inside Climate News that federal leadership could break the deadlock between the states, a move that Arizona Gov. Katie Hobbs has called for recently. 

Buschatzke feels that nothing the Upper Basin has proposed would withstand scrutiny from Arizona legislators, who would have to approve it. Visibly upset, he said the Upper Basinโ€™s claim that they canโ€™t take more cuts is โ€œabsurdโ€ and is based on them not getting their โ€œpaperโ€ waterโ€”a term used to refer to water that exists legally but has never been put to use or proven to currently be available. 

โ€œThey need mandatory conservation that results in more water being in Lake Powell that can be moved to Lake Mead,โ€ he said.

Upper Basin negotiators counter that it is not their responsibility to cut their use to accommodate Lower Basin users who have long overdrawn the system. โ€œWe cannot subsidize overuse,โ€ said Becky Mitchell, Coloradoโ€™s negotiator.

Lower Basin water use since 1964. 2025 data provisional, based on USBR projections Oct. 29, 2015.

At one point, the Lower Basin used several million acre-feet more water per year than it was allocated, but it has since reduced its consumption and now uses less than it is legally entitled to. California, the riverโ€™s biggest user, touted drastic conservation measures that have reduced water use to its lowest levels since the 1940s, despite booming growth in the state. Lower Basin leaders argue, too, that the regionโ€™s biggest cities, farms and economic outputs from the river are within the three states.

Upper Basin officials argue they have the right to grow as the Lower Basin has, and itโ€™s unfair for those four states to sacrifice their future.

Earlier this week, leaders in both basins saw a preview of the federal governmentโ€™s draft environmental review, which included a range of options for managing Lake Powell and Lake Mead. Some in the Lower Basin expressed concern that the options relied too heavily on them making future cuts. Hamby, Californiaโ€™s negotiator, emphasized that if the basin states eventually reach an agreement, it will determine how the federal government manages the river.

โ€œUltimately, none of it should matter if we get to a seven-state consensus,โ€ said Hamby, who is also a board member of Southern Californiaโ€™s Imperial Irrigation District, the riverโ€™s single-largest water user. โ€œBut as part of the [environmental review] process, what we look forward to seeing from California is an equally balanced risk across the basin that motivates people to develop a seven-state consensus.โ€

Brandon Gebhart, Wyomingโ€™s state engineer and Colorado River negotiator, called the analysis โ€œbroad enough to accommodate any seven-state consensus agreementโ€ in an email.

Andrea Travnicek, assistant secretary for water and science at the Interior Department, said the government expects to publish the environmental impact statement in the last week of December or first week of January. 

Despite the urgency, conference attendees werenโ€™t surprised that negotiations remain stalled and no deal appeared imminent.

Cynthia Campbell, the director of policy innovation for the Arizona Water Innovation Institute at Arizona State University, said she expects one of two outcomes in the next 18 months, and perhaps both: the system will collapse or there will be litigation.

The public, she said, will then ask what happened, and leaders will have no good answers.

โ€œI came with very low expectations, and they were met,โ€ she said.

December 18, 2025

In the next few weeks, the public will get their first look at a critical document two and a half years in the making that will define how the Colorado River is managed for the next decade.

The Bureau of Reclamation โ€“ which manages water in the West under the Interior Department โ€“ is on track to release a draft environmental review by early January with a range of options to replace the riverโ€™s operating rules, which are set to expire at the end of 2026.

Several elements of the draft were shared during the annual Colorado River Water Users Associationโ€™s conference in Las Vegas at Caesars Palace Wednesday.

Negotiations between federal officials and the seven western states that rely on the Colorado River have largely remained behind closed doors since 2023, but any new operating rules will be required to go through a public environmental review process before a final decision can be made.

Interior Department Assistant Secretary for Water and Science, Andrea Travnicek, said the agency is committed to meeting the self-imposed January deadline in order to finalize new rules before the current ones expire.

โ€œThe Department of the Interior recognizes a shrinking timeline is in front of us in order to operate under a new potential agreement,โ€ Travnicek said.

In an unusual move, federal water officials said the draft will not identify which set of operating guidelines the federal government would prefer, which is typically included in environmental reviews. 

โ€œWe will not be identifying a preferred alternative, but we anticipate the identification of that between the draft and the final,โ€ said Bureau of Reclamationโ€™s senior water resource program manager, Carly Jerla.

Instead, the draft environmental review will list a broad range of possible alternatives designed to enable states to continue working towards a seven-state consensus agreement on how to share the riverโ€™s shrinking water supply. 

โ€œWe want to continue to facilitate, but not dictate these operations. The goal here is to inform decision makers and encourage parties to adopt agreements that put consultation and negotiation first,โ€ Jerla continued.

Lower Basin states โ€” California, Arizona, and Nevada โ€” and Upper Basin states โ€” Colorado, Wyoming, Utah and New Mexico โ€” have been at an impasse for months over how to manage the Colorado Riverโ€™s shrinking water supplies.

Last month, the states missed a federally-imposed deadline to submit a preliminary seven-state consensus plan that could replace the riverโ€™s operating guidelines after days of intense closed-door negotiations.

Statesโ€™ last chance to share a final consensus-based plan will be mid-February 2026 in order to reach a final agreement in the summer  with implementation of the new guidelines beginning in October 2026.

The Bureau of Reclamationโ€™s Acting Commissioner Scott Cameron said he and other federal officials have intensified efforts to bring states to a consensus, flying out West every other week since early April to meet with the seven statesโ€™ river negotiators.

โ€œThere are a number of issues from decades past that some people are having some difficulty getting past,โ€ Cameron said, adding that states must โ€œbe willing to set aside previous perceived inequities and unfairness.โ€

One of the biggest disagreements between the Upper and Lower Basin states is over which faction should have to cut back on their water use, and by how much.

Lower Basin states want all seven Colorado River states to share mandatory water cuts during dry years under the new guidelines. The Upper Basin, which is not subject to mandatory cuts under current guidelines, say they already use much less water than downstream states and should not face additional cuts. [ed. Also, the UB states face cuts every year from Mother Nature with the variability, but generally lower, snowpack each season.]

Despite states missing past deadlines, Cameron said he was โ€œcautiously optimisticโ€ states will reach a consensus deal by the February deadline.

โ€œItโ€™s not unusual in the negotiating process that tougher decisions get made the closer you get to the deadline. And frankly, there are tough decisions that have to be made,โ€ Cameron said.

On Tuesday, Californiaโ€™s biggest water districts said they were willing to โ€œset aside many of their legal positionsโ€ in order to reach a seven-state agreement.

The Bureau of Reclamation provided a broad overview of the components that will be included in draftโ€™s range of options, including guidelines to reduce water deliveries from Lake Mead during shortages, coordinated reservoir operations for Lake Mead and Lake Powell, and storage and delivery mechanisms for conserved water.

Jerla, Reclamationโ€™s senior water resource program manager, said the draft alternatives will include some components previously proposed by states.

She said the agency has adopted a number of temporary operational agreements since 2008 to address changing conditions on the river. Those agreements have served as test runs for a long term agreement and emphasized the need for more flexibility when managing the river from year-to-year.

โ€œWe want to preserve ourselves the flexibility to come back to the table, to do reviews, to make consensus adjustments if needed,โ€ Jerla said.

That flexibility to operations will likely be needed again this year due to a less-than-average upcoming snow season, that combined with a dry spring or early summer in 2026, could create conditions for another low runoff year.

โ€œWeโ€™re monitoring the forecast, and weโ€™re seeing not a great start to water year 2026. Itโ€™s still early in the year, but the way things are setting up it isnโ€™t looking good,โ€ Jerla said.

The two biggest reservoirs in the country, Lake Powell and Lake Mead, are currently at a fraction of their full capacity. Lake Mead is at 32% capacity, while Lake Powell is at 28%. 

Additionally, water inflow into the reservoirs in 2026 are projected to most likely be 75% of the average, according to the federal agency. The minimum probable inflow forecast for 2026 is 44% of average, indicating a potentially very dry year.

LAS VEGAS โ€”ย About [1,700] people from every corner of the Colorado River Basin flocked to the palm tree-lined Caesars Palace casino in Las Vegas this week thirsty for insights into the stalled negotiations over the future management of the river.

New insights, however, were sparse as of Tuesday morning.

The highly anticipated Colorado River Water Users Association conference is the largest river gathering of the year. Itโ€™s a meet up where federal and state officials like to make big announcements about the water supply for 40 million people, and when farmers, tribal nations, city water managers, industrial representatives and environmental groups can swap strategies in hallway chats.

The meetings started Tuesday morning before the conference officially kicked off. Officials from basin states, including Colorado, set the tone by digging into their oft-repeated rhetoric about the worrisome conditions in the basin, impacts in their own states and conservation efforts. Conference-goers pushed state leaders for more transparency and progress in the discussions over the riverโ€™s future.

The basinโ€™s main reservoirs, lakes Mead and Powell, have fallen to historic lows despite pouring state and federal dollars into broad conservation efforts, said Commissioner Becky Mitchell, Coloradoโ€™s governor-appointed negotiator on Colorado River issues.

โ€œWeโ€™re in a precarious time because none of that is enough,โ€ Mitchell told hundreds of audience members during an Upper Colorado River Commission meeting Tuesday. โ€œIt has not been enough.โ€

Natural flows โ€” which is a calculation of how much water would pass Lees Ferry without upstream human intervention โ€” has trended downward since the mid-1980s. Even before that, however, the river rarely carried as much water as the drafters of the 1922 Colorado River Compact presumed it did. They based the Compact on a median flow of 20 million acre-feet. The 1906-2025 median flow has actually been just 14.3 MAF, while the most recent six-year average has been just over 10 MAF. Data source: Bureau of Reclamation via The Land Desk.

As the riverโ€™s water supply is strained by a 26-year drought and human demands, officials are trying to replace an expiring agreement from 2007, which manages how Mead and Powell capture water from upstream states and release it downstream for water users in Arizona, California, Nevada and Mexico.

The Department of the Interior is managing the effort, dubbed the post-2026 process, but deciding new rules is simpler said than done: Basin officials will have to address a changing climate and decide on painful water cuts going forward.

The Interior Department has given the seven basin states until Feb. 14 to reach a consensus. If they can agree, the feds will use the statesโ€™ proposal to manage the basinโ€™s reservoirs. If not, the federal officials will decide what to do.

Officials from the Upper Basin states โ€” Colorado, New Mexico, Utah and Wyoming โ€” did not share examples of progress in the post-2026 negotiations. They said the basinโ€™s water cycle, not its legal issues, are the main problem.

โ€œItโ€™s not political positions. Itโ€™s not legal interpretations,โ€ Brandon Gebhart, Wyomingโ€™s top negotiator, said. โ€œItโ€™s the hydrology of the entire basin.โ€

Others, including some of the 30 tribes in the basin, saw it differently. Some tribal representatives called for more transparency. Others said they couldnโ€™t support a plan that is geared toward sending water to downstream states.

โ€œDespite those that think hydrology is the problem, itโ€™s not, and it canโ€™t always be the scapegoat,โ€ said Kirin Vicenti, water commissioner for the Jicarilla Apache Nation, located within New Mexico just south of the Colorado state line. โ€œOur planning and policies must allow flexibility, and innovative and dynamic solutions.โ€

Relationships between upstream states and Lower Basin states โ€” Arizona, California and Nevada โ€” have been strained since the post-2026 effort kicked into gear in 2022 and 2023.

On the other side of the casino wall from the Upper Basin meeting, the Colorado River Board of California met Tuesday morning. Each audience could hear muffled clapping from the other room as the officials spoke to their constituents.

โ€œWe know one thing for sure, which is that we have a smaller river and that requires less use,โ€ JB Hamby, chairman of the Colorado River board and Californiaโ€™s top negotiator, told the gathering.

He lauded Californiaโ€™s โ€œmassiveโ€ and expensive efforts to address the riverโ€™s shrinking supply while still growing the stateโ€™s economy and agriculture industry.

Lower Basin water use since 1964. 2025 data provisional, based on USBR projections Oct. 29, 2015.

California has cut its water use to 3.76 million acre-feet, the lowest it has been since 1949, state officials said. It has a proposed plan to conserve 440,000 acre-feet of river water per year.

One acre-foot roughly equals the annual water use of two to three households.

โ€œWe hear lots of applause lines from our friends next door, and we encourage them to take some examples from what California has been able to put together,โ€ Hamby said. โ€œWe must all live with the resources we have, not the ones that we wish for.โ€

Crossing basin lines

While the states might be divided in water politics, conference attendees like Ken Curtis of Colorado moved between the rooms to hear each groupโ€™s discussion.

โ€œWe appear to be talking past each other,โ€ said Curtis, the general manager of the Dolores Water Conservancy District in southwestern Colorado.

Some water managers from central Utah said they were already looking beyond the current negotiations to the next few decades. The basinโ€™s challenges donโ€™t end next fall โ€” this is just a speed bump in a long future ahead, they said.

Others were waiting for updates from federal officials, scheduled for Wednesday. The Department of the Interior is set to release a highly anticipated look at different options for how to manage the basin around the end of the year.

Curtis said he is at the conference mainly to learn how other states were grappling with the tough water conditions and to get more insight into the negotiations beyond whatโ€™s in the media, he said.

โ€œSqueezing it (water) out of the Upper Basin isnโ€™t going to make enough water for the Lower Basin demands,โ€ Curtis said. โ€œAnd that may be a biased view, obviously, so Iโ€™m trying to get a little bit beyond my own biases.โ€

Where the wild things thrive: Finding and protecting natureโ€™s #ClimateChange safeย havens — Toni Lyn Morelli and Diana Stralberg (TheConversation.com)

The idea began in Californiaโ€™s Sierra Nevada, a towering spine of rock and ice where rising temperatures and the decline of snowpack are transforming ecosystems, sometimes with catastrophic consequences for wildlife.

The prairie-doglike Beldingโ€™s ground squirrel (Urocitellus beldingi) had been struggling there as the mountain meadows it relies on dry out in years with less snowmelt and more unpredictable weather. At lower elevations, the foothill yellow-legged frog (Rana boylii) was also being hit hard by rising temperatures, because it needs cool, shaded streams to breed and survive.

As we studied these and other species in the Sierra Nevada, we discovered a ray of hope: The effects of warming werenโ€™t uniform.

We were able to locate meadows that are less vulnerable to climate change, where the squirrels would have a better chance of thriving. We also identified streams that would stay cool for the frogs even as the climate heats up. Some are shaded by tree canopy. Others are in valleys with cool air or near deep lakes or springs.

These special areas are what we call climate change refugia.

Identifying these pockets of resilient habitat โ€“ a field of research that was inspired by our work with natural resource managers in the Sierra Nevada โ€“ is now helping national parks and other public and private land managers to take action to protect these refugia from other threats, including fighting invasive species and pollution and connecting landscapes, giving threatened species their best chance for survival in a changing climate.

Across the world, from the increasingly fire-prone landscapes of Australia to the glacial ecosystems at the southern tip of Chile, researchers, managers and local communities are working together to find and protect similar climate change refugia that can provide pockets of stability for local species as the planet warms.

A new collection of scientific papers examines some of the most promising examples of climate change refugia conservation. In that collection, over 100 scientists from four continents explain how frogs, trees, ducks and lions stand to benefit when refugia in their habitats are identified and safeguarded.

Saving songbirds in New England

The study of climate change refugia โ€“ places that are buffered from the worst effects of global warming โ€“ has grown rapidly in recent years.

In New England, managers at national parks and other protected areas were worried about how species are being affected by changes in climate and habitat. For example, the grasshopper sparrow (Ammodramus savannarum), a little grassland songbird that nests in the open fields in the eastern U.S. and southern Canada, appears to be in trouble.

We studied its habitats and projected that less than 6% of its summer northeastern U.S. range will have the right temperature and precipitation conditions by 2080. https://www.youtube.com/embed/W2VmrdbCbmU?wmode=transparent&start=0 The grasshopper sparrow. American Bird Conservancy

The loss of songbirds is not only a loss of beauty and music. These birds eat insects and are important to the balance of the ecosystem.

The sand plain grasslands that the grasshopper sparrow relies on in the northeastern U.S. are under threat not only from changes in climate but also changes in how people use the land. Public land managers in Montague, Massachusetts, have used burning and mowing to maintain habitat for nesting grasshopper sparrows. That effort also brought back the rare frosted elfin butterfly for the first time in decades.

Protecting Canadaโ€™s vast forest ecosystems

In Canada, the climate is warming at about twice the global average, posing a threat to its vast forested landscapes, which face intensifying drought, insect outbreaks and destructive wildfires.

We have been actively mapping refugia in British Columbia, looking for shadier, wetter or more sheltered places that naturally resist the worst effects of climate change.

The mapping project will help to identify important habitat for wildlife such as moose and caribou. Knowing where these climate change refugia are allows land-use planners and Indigenous communities to protect the most promising habitats from development, resource extraction and other stressors.

British Columbia is undertaking major changes to forest landscape planning in partnership with First Nations and communities.

Lions, giraffes and elephants (oh, my!)

On the sweeping vistas of East Africa, dozens of species interact in hot spots of global biodiversity. Unfortunately, rising temperatures, prolonged drought and shifting seasons are threatening their very existence.

In Tanzania, working with government agencies and conservation groups through past USAID funding, we mapped potential refugia for iconic savanna species including lions, giraffes and elephants. These areas include places that will hold water in drought and remain cooler during heat waves. The iconic Serengeti National Park, home to some of the worldโ€™s most famous wildlife, emerged as a key location for climate change refugia.

Combining local knowledge with spatial analysis is helping prioritize areas where big cats, antelope, elephants and the other great beasts of the Serengeti ecosystem can continue to thrive โ€“ provided other, nonclimate threats such as habitat loss and overharvesting are kept at bay.

The Tanzanian government has already been working with U.S.-funded partners to identify corridors that can help connect biodiversity hot spots.

Hope for the future

By identifying and protecting the places where species can survive the longest, we can buy crucial decades for ecosystems while conservation efforts are underway and the world takes steps to slow climate change.

Across continents and climates, the message is the same: Amid our rapidly warming world, pockets of resilience remain for now. With careful science and strong partnerships, we can find climate change refugia, protect them and help the wild things continue to thrive.

๐Ÿฅต Aridification Watch ๐Ÿซ

A new report from the Colorado River Research Group, aptly named โ€œDancing with Deadpool,โ€ paints a grim picture of the critical artery of the Southwest. Reservoir and groundwater levels are perilously low, the 25-year megadrought is likely to persist โ€” perhaps for decades, and the collective users of the river have yet to develop a workable plan for cutting consumption and balancing demand with the riverโ€™s dwindling supply.

Amid all the darkness however, the report also delivers a few glimmers of hope, noting that mechanisms do exist to avert a full-blown crisis, and that humans do have the power to slow or halt human-cased global heating, which is one of the main drivers of reduced flows in the river.

Those reduced flows seem like a good place to start, since the Colorado River Basin is experiencing the very phenomenon that Jonathan Overpeck and Brad Udall write about in the second chapter, โ€œThink Natural Flows Will Rebound in the Colorado River Basin? Think Again.โ€

Natural flows โ€” which is a calculation of how much water would pass Lees Ferry without upstream human intervention โ€” has trended downward since the mid-1980s. Even before that, however, the river rarely carried as much water as the drafters of the 1922 Colorado River Compact presumed it did. They based the Compact on a median flow of 20 million acre-feet. The 1906-2025 median flow has actually been just 14.3 MAF, while the most recent six-year average has been just over 10 MAF. Data source: Bureau of Reclamation.

The authors call the Southwest โ€œmegadrought country,โ€ since tree rings and other sources show that severe, multi-decadal dry spells โ€” like the one gripping the region currently โ€” have occurred somewhat regularly over the last 2,000 years. The current drought, then, is likely a part of this natural climate variability.

But thereโ€™s a catch: The previous megadroughts most likely resulted from, primarily, a lack of precipitation. The current dry-spell is also due to lack of precipitation, but it is intensified by warming temperatures, which are the clear and direct result of climate change. They also find evidence that climate change may also be exacerbating the current climate deficit.

The takeaway is that even when we move through the current dry part of the cycle, the increasingly higher temperatures will offset some of the added precipitation and continue to diminish Colorado River flows. And, when the natural cycle comes back around to the drought side, itโ€™s going to be even worse thanks to climate change.

Water year 2026 is so far looking like an example of the former, with normal to above-normal precipitation accumulating, but as rain, not as snow, leaving much of the West with far below normal snowpack levels.

If the trend continues, it will not bode well for the Colorado River, according to the chapter written by Jack Schmidt, Anne Castle, John Fleck, Eric Kuhn, Kathryn Sorensen, and Katherine Tara. In an updated version of aย paper they put out in September, they find that if water year 2026 (which weโ€™re about 2.5 months into) is anything like water year 2025, Lake Powell is in trouble, and โ€œlow reservoir levels in summer 2026 will challenge water supply management, hydropower production, and environmental river management.โ€

The top water users on the Lower Colorado River Basin. Imperial Irrigation District in southern California once again tops the list. But itโ€™s notable how much consumption theyโ€™ve cut since 2003; the IID is expected to use even less water in 2025. Nevada is broken out as a state here because of the way the accounting works. Nearly all of Nevadaโ€™s Colorado River allocation goes to Southern Nevada and the Las Vegas metro area. Data source: Bureau of Reclamation.

In order to avoid a full-blown crisis in the near-term, Colorado River users must significantly and quickly cut water consumption โ€” independent of whatever agreement the states come up with for dividing the riverโ€™s dwindling waters after 2026.

While there is a long-running debate over whether the Upper Basin or the Lower Basin will have to bear the brunt of those cuts, the math makes it indisputable that the agricultural sector in both basins will have to pare down its collective consumption. Thatโ€™s because irrigated agriculture accounts for about 74% of all direct human consumptive use on the River, or about three times more than municipal, commercial, and industrial uses.

Chart showing how water from the Colorado River is used. Source: โ€œNew accounting reveals why the Colorado River no longer reaches the sea,โ€ by Brian Richter et al.

Thatโ€™s why, in recent years, the feds and states have paid farmers to stop irrigating some crops and fallow their fields. While this method has achieved meaningful cuts in overall water use in those areas, it is in most cases not sustainable because the deals are temporary, and because they rely on iffy federal funding. So, in another of the reportโ€™s chapters, Kathryn Sorensen and Sarah Porter offer a different proposal: The federal government should simply purchase land from willing sellers and stop irrigating it (or at least compensate landowners for agreeing to stop or curtail irrigation permanently).

They emphasize that this is not a โ€œbuy-and-dryโ€ proposition, where a city buys out the water rights of farms to serve more development. That doesnโ€™t actually save any water, since the city is still using it, and it wrecks farms and communities. Instead, this proposal would actually convert the farmland into public land, and put the water back into the river. This proposed program would target high-water-use, low economic-water-productivity land in situations where the water savings would benefit the environment and the land transfer would help local communities.

Even then, this would be disruptive, in that it would take land out of agriculture and potentially remove farms โ€” and the farmers โ€” from the community. There would also be the question of how toย manage the freshly fallowed fieldsย so that they donโ€™t become weed-infested wastelands or sources of airborne, snow-melting dust.

In the following chapter, a quartet of authors suggests a slightly softer approach, in which farmers adapt to dwindling water amounts by shifting crops or to reduce cattle herd sizes or approaches.

The report concludes with a call for a basin-wide approach to managing the Colorado River, and the creation of an entity that would address Colorado River issues in a more comprehensive, transparent, and inclusive way. The current approach, which arbitrarily cuts the watershed in half along an imaginary line, pitting one set of states against another while excluding sovereign tribal nations, and trying to operate within an outdated framework known as the Law of the River, is an opaque mess that has thus far resulted only in gridlock.

The authors propose, instead:

And, finally, a little smidgeon of hope from the reportโ€™s second chapter, although itโ€™s hard to be hopeful about reversing climate change in times like these and with a presidential administration intent on burning more and more fossil fuels โ€ฆ

๐Ÿฆซ Wildlife Watch ๐Ÿฆ…

The News: Colorado Parks and Wildlife last week thanked New Mexico wildlife officials for successfully capturing gray wolf 2403, a member of Coloradoโ€™s Copper Creek pack that had roamed over the state line. The wolf was re-released in Grand County, Colorado, where officials hope it will find a mate.

The Context: WTF!? Are these folks trying to bring an extirpated species back to a state similar to the one that existed before it was systematically slaughtered โ€” i.e. the โ€œnaturalโ€ state โ€” or are they running a zoo? 

The CPW said that the wolfโ€™s capture was in compliance with an agreement with bordering states that is purportedly intended to โ€œprotect the genetic integrity of the Mexican wolf recovery program, while also establishing a gray wolf population in Colorado.โ€

Iโ€™m no wildlife biologist, but it sure does seem to me that if a gray wolf from Colorado heads to New Mexico in search of a mate, as is their instinctual tendency, then thatโ€™s a good thing. And trying to confine the wolves to artificial and arbitrary political boundaries is counterproductive.

โ€œHistorically, gray wolf populations in western North America were contiguously distributed from northern arctic regions well into Mesoamerica as far south as present day Mexico Cityโ€ explained David Parsons, former Mexican Wolf Recovery Coordinator for the US Fish and Wildlife Service in a written statement. โ€œThe exchange of genes kept gray wolf populations both genetically and physically healthy, enhancing their ability to adapt and evolve to environmental changes.โ€ He added that 2403โ€™s walkabout, along with that of โ€œTaylor,โ€ the Mexican gray wolf that has defied attempts to constrain him to southern New Mexico by traveling into the Mt. Taylor region, were โ€œsimply retracing ancient pathways of wolf movements. Rather than being viewed as a problem, these movements should be encouraged and celebrated as successful milestones toward west-wide gray wolf recovery efforts.โ€

Amen to that. 

Itโ€™s clearly very tough to run a predator reintroduction program in the rural West, fraught as it is with political and cultural complications. And I respect and admire the folks that are running the project, and understand they are working within serious constraints. Still, there has to be a better way to let nature run its course.

#Breckenridge and #Gypsum Join Effort to Secure Shoshone Water Rights — Lindsay DeFrates (#ColoradoRiver District) #COriver #aridification

December 15, 2025

The effort to permanently protect the historic Shoshone water rights gained additional momentum as two more west slope communities committed funding in their 2026 budgets toward the Colorado River Districtโ€™s $99 million purchase agreement with Xcel Energy. The Town of Breckenridge has pledged $100,000, and the Town of Gypsum has committed $15,000, underscoring the importance of reliable Colorado River flows for communities from the headwaters to the state line and beyond.

By committing financial support for the Shoshone Water Rights Preservation Project, Breckenridge and Gypsum join a large and growing coalition of Western Slope partners working to safeguard flows that support local economies, healthy rivers, and long-term water security for Colorado.

โ€œThe Shoshone water rights are a cornerstone of the Colorado River system and a critical part of protecting our quality of life in the high country,โ€ said Breckenridge Mayor Kelly Owens. โ€œBreckenridge is proud to stand with partners across the West Slope and headwaters region to keep water in the river, support our outdoor recreation economy, and protect this vital resource for generations to come.โ€

Town of Gypsum via Vail.net

โ€œLook, in Gypsum we see it every single day, our local ranches, our jobs, our families all depend on the Eagle and the Colorado running strong and flowing,โ€ said Gypsum Mayor Steve Carver.  โ€œBacking Shoshone just makes sense. It gives us some certainty when water gets tight. Weโ€™re happy to jump in with everybody else and keep that water right here on the Western Slope.โ€

The Shoshone Water Rights Preservation Coalition, led by the Colorado River District, now includes 35 local governments, water entities, and regional partners across the Western Slope, as well as support from across the state. Together, these partners have committed over $37.3 million toward the $99 million purchase price, in addition to state and federal investments to protect a critical piece of Coloradoโ€™s water security.

โ€œCommunities across the West Slope continue to step up together in a powerful way,โ€ said Andy Mueller, general manager of the Colorado River District. โ€œSupport from Breckenridge and Gypsum reflects a shared understanding that Shoshone is about more than one community or region. Itโ€™s about working together to keep the Colorado River and its tributaries flowing for the environment, agriculture, recreation and local communities across Colorado that rely on this water.โ€

Shoshone Hydroelectric Plant back in the days before I-70 via Aspen Journalism

The Shoshone hydroelectric plant, located in Glenwood Canyon, holds nonconsumptive senior water rights that date back to 1902. These rights are essential for supporting flows in the Colorado River, benefiting agriculture, recreation, rural economies, and water users across the West Slope and beyond.

In December 2023, the Colorado River District entered a purchase and sale agreement with Xcel Energy to acquire and permanently protect the water rights, with plans to negotiate an instream flow agreement with the Colorado Water Conservation Board. This agreement would safeguard future flows, regardless of the Shoshone plantโ€™s operational status.

In January 2025, the Bureau of Reclamation awarded $40 million in federal funding through a program authorized by the Inflation Reduction Act. The River District continues to work with the Bureau and remains optimistic that the projectโ€™s broad support and clear public benefit will secure the necessary federal funds to complete this once-in-a-generation investment.

The Erosion of the Colorado River โ€œSafety Netsโ€ is Alarming — Doug Kenney (#ColoradoRiver Research Group) #COriver #aridification

Graphic credit: Colorado River Research Group from the report “Dancing with Deadpool”

Click the link to access the report Dancing with Deadpool on the Getches-Wilkinson Center website (Doug Kenney1):

The rapid loss of storage in Lakes Mead and Powell is certainly deserving of the attention and angst it has generated and continues to generate, but it is the tip of larger trends altering the landscape of risk in the basin. The dismantling of many other โ€œsafety nets,โ€ defined broadly, is happening at a pace far surpassing the already unprecedented declines in reservoir storage. Presumably thatโ€™s not an immediate problem if new post-2026 rules are able to recover and protect storage in Mead and Powell (and some of the other upstream facilities), but does anyone have that much faith in the power of new reservoir operating rules to combat the forces that have brought us to this point? What about when we have a 10 million acre-feet/year river?

(b) Spatial variation in TWS trends for the Colorado River Basin for the investigated period (mm/year) (c) Time series comparison of the change in storage ฮ”S/ฮ”t derived from the water balance equation (Equation 1) and GRACE/FO. ฮ”S/ฮ”t calculated from GRACE/FO TWS anomalies in km3. The light shading represents uncertainties.

From Groundwater to Governance

Perhaps the most obvious of those other diminishing safety nets is groundwater. Data on groundwater reserves throughout the basin is spotty at best. One approximation of a truly regional assessment comes from a creative use of satellite-based toolsโ€”namely NASAโ€™s GRACE (Gravity Recovery and Climate Experiment) system that can detect tiny changes in gravitational forces associated with the fluctuating mass of aquifers losing (or gaining) storage. Those findings paint a truly disturbing picture. Despite the familiar (and troubling) images of bathtub rings emerging at Mead and Powell, researchers using GRACE data now estimate that, from 2002 to 2024, nearly two-thirds of storageโ€”both surface and groundwaterโ€”lost in the Colorado River Basin actually came from groundwater depletions.2ย Significant groundwater losses have occurred throughout the basin, but the problem is particularly acute in Arizona and is likely to accelerate as shortages in Central Arizona Project (CAP) deliveries are likely offset by groundwater pumpingโ€”an ironic outcome given that CAP was originally proposed as the solution to groundwater mining in the region. Simply shifting unsustainable surface water uses to unsustainable groundwater uses does nothing to address the core mismatch of supplies and demands.

A very different and multi-faceted trend undercutting the regional safety nets is happening within the federal government, where federal agencies, programs and science programs are being systematically dismantled under the guise of โ€œefficiency.โ€ Itโ€™s hard to understate the significance of these actions, as it is the federal government that, presumably, has the scope, mandate and resources to oversee the entirety of the River and the full diversity of its roles and values. Interior Department agencies in 2025, like much of the overall federal bureaucracy, have been tasked to achieve significant staffing reductions, and to eliminate (or significantly scale back) spending on key water conservation programsโ€”including programs under the Inflation Reduction Act (IRA) and WaterSMART.3

Additionally, agencies across the federal landscape have mobilized to coerce and shut down climate-related science and scientists, despite the nearly universal acknowledgment among water managers of the central role of climate change in the unfolding crisis.4 Collectively these efforts constitute a systematic effort to discredit and hide the primary cause of the broken water budget, while sabotaging the most effective coping mechanisms available. As members of the research community, the Colorado River Research Group (CRRG)unfortunately has a front-row seat to this culling of the people and programs essential to long-term data collection and analysis. It defies logic, and is dangerous.

Unfortunately, hostility toward the people and programs essential to responding to the Colorado River crisis is not the full extent of federal obstruction. One largely unappreciated threat to the water budget resulting from federal policy shifts comes from efforts to โ€œre-carbonizeโ€ (and accelerate) water-intensive energy generation, in part to meet the demands of AI, a particularly troubling trend given that the previous emphasis on renewable energy generation and enhanced energy conservation was one of the few positive trends working to repair the regional water budget.5ย Attempts to weaken or dismantle bedrock environmental laws, such as NEPA and the Endangered Species Act, are an additional wildcard likely to inflict irreparable harm on already strained species and ecosystems.6

Given the turmoil at the federal level, itโ€™s tempting to absolve the States for stubbornly clinging to a policy making system reliant on 7-state dealmaking, but that would ignore the reality that the governance of the river has been a problem for decades. A seemingly never-ending series of crisis-inspired negotiations, held in largely secretive forums without direct tribal involvement or tools for meaningful public or scientific engagement, is an uninspired way to manage and protect the economic, cultural and environmental heart of the American Southwest. The river is too big and too important to govern in such an ad hoc and primitive manner. [ed. emphasis mine]

That this approach mostly โ€workedโ€ to keep deliveries flowing for so longโ€”except, of course, for the tribes and the environmentโ€”rested, in part, on the accepted norm that decisions would emerge collaboratively from the States and would not spill over to the federal courts. But even that governance safety net is eroding, as the States seem to be increasingly resignedโ€”and almost โ€œcomfortableโ€โ€”with the notion that the resolution of existing conflicts may not emerge from a negotiated 7-state agreement. For those parties and viewpoints that have historically been left out of the state-dominated processes and the resulting agreements, then maybe this prospect is welcome. But all would concede that would be a stunning outcome with ramifications that are difficult to predict.

Ever since the Arizona v. California experience, the use of litigation to resolve interstate (and/or interbasin) conflicts in the basin has been a third rail issue, and for very good reasons. As shown by the basinโ€™s earlier foray into Supreme Court action, the process would undoubtedly be lengthy, expensive, and likely to create as many issues and questions as it resolves. It certainly wouldnโ€™t reduce risk, as the states, and the water management community more broadly, would lose control over the process of managing the shared resource. In fact, judicial intervention might be the impetus to trigger yet another traditionally feared decision pathway to be invokedโ€”a Congressional rewrite of river allocation and managementโ€”either before or after the litigation concludes. In this setting, the extreme disparity in political influenceโ€”as measured by the number of Congressional representativesโ€”between the Upper and Lower Basin is an obvious concern, as is the realization that congressional involvement means the future of the Colorado now becomes a national issue and, potentially, a bargaining chip to be used in the political logrolling necessary to enact legislation in dozens of otherwise unrelated areas.

Rowing in the Wrong Direction

Managing water in the arid and semi-arid West is often more about risk than water. From the seniority concept in prior appropriation to the sizing of infrastructure based on low probability events, the goal of water management is often to clearly define and then minimize the risks of running out. Given that, youโ€™d think that the communities dependent upon Colorado River water would be more committed to protecting (and enhancing) the safety nets that are increasingly critical as storage in Lakes Mead and Powellโ€”the basinโ€™s primary risk management toolsโ€”increasingly flirt with deadpool. But at the basin scale, thatโ€™s typically not what I see. Sure, individual water managers serving major cities or districts have their own risk management plans focusing on everything from new infrastructure to market solutions, but thatโ€™s far from a comprehensive or integrated approach, and safety nets designed by and for the โ€œestablished playersโ€ only deepen the inequities that increasingly divide the Colorado River community.

Thereโ€™s a lot of work left to do in this basin, both prior and after the 2026 deadline. Viewing the problems through the lens of risk management is not a bad place to start. But if doing so, itโ€™s also not a bad idea to remember that poor risk management often comes at expense of diminished equityโ€”an indispensable element of an equitable apportionment. Numerous examples around the world remind us that water scarcity can be the impetus for joint problem-solving in a spirit of camaraderie and mutual support, or it can sharpen and refine alliances that further distance the powerful from the weak. In this regard, Iโ€™m inclined to think we are rowing in the wrong direction.ย โ—

Historic Step Forward to Secure Environmental Flows in the #ColoradoRiver — Hannah Holm (AmericanRivers.com) #COriver #aridification

December 11, 2025

On the evening of November 19, a packed conference room in the Denver West Marriott erupted in cheers when theย Colorado Water Conservation Board approvedย one of the largest ever dedications of water for the environment in Coloradoโ€™s history. This new deal, if completed, will ensure that water currently running through the aging Shoshone Hydropower Plant on the Colorado River, deep in the heart of Glenwood Canyon, will keep flowing through the canyon when the plant eventually goes off-line. Itโ€™s not a sure thing yet โ€“ water court wrangling over the details and financial hurdles remain. But the Boardโ€™s action was a crucial step forward.ย 

Currently, when the plant is running full steam, 1,400 cubic feet/ second (think 1,400 basketballs full of water passing by every second) is diverted out of the river into a tunnel and then into massive pipes visible against the canyon walls, where the power of falling water spins turbines to generate electricity. The water is then returned back to the river. Under the new deal, when the plant stops operating (it is over 100 years old and vulnerable to rockfall), the water would instead stay in the river, vastly improving conditions for fish and the bugs they eat in the 2.4-mile reach between the diversion and the powerplantโ€™s return flows. The dedication of the plantโ€™s water rights to that stretch of river would bring benefits that ripple hundreds of miles up and downstream because of the crucial role these water rights play in controlling the riverโ€™s flow through Western Colorado.ย ย 

Shoshone Power Plant, Colorado | Hannah Holm

In Colorado, as in most of the West, older water rights take priority over newer ones when thereโ€™s not enough water to satisfy everyoneโ€™s claims.ย  On the Colorado River, the Shoshone Hydropower rights limit the amount of water that can be taken out of the river upstream by junior rights that divert water from the riverโ€™s headwaters through tunnels under the Continental Divide to cities and farms on the eastern side of the Rocky Mountains. The new deal to enable the Shoshone rights to be used for environmental flows would preserve those limitations on transmountain diversions in perpetuity.

Upstream from the power plant, near the ranching town of Kremmling, Colorado, the river carries less than half the water it would without the existing transmountain diversions. This stresses fish populations and the iconic cottonwood groves that line the river. The Shoshone rights downstream prevent these diversions from being even larger. Because the power plant returns all the water it uses to the river without consuming it, the water continues to provide benefits downstream from the plant to rafters, farms, cities and four species of endangered fish that exist only in the Colorado River Basin. Securing these flows for the future is particularly important as climate change continues to reduce the riverโ€™s flow, which has already declined by roughly 20% over the past two decades.  

The people cheering in the hearing room represented cities, towns, counties and irrigation districts from up and down the Colorado River. Their entities had pledged ratepayer and taxpayer dollars to help secure the rights in the complex transaction spearheaded by the Colorado River Water Conservation District. Environmental organizations, including American Rivers, Audubon, Trout Unlimited and Western Resource Advocates, were also parties to the hearing and supportive of the deal, but were vastly outnumbered.  

The Coloradans cheering in that room were there because their constituentsโ€™ livelihoods, clean drinking water and quality of life depend on a living Colorado River. American Rivers is proud to stand with them and will continue advocating for the completion of this historic water transaction.

Here’s the preface:

Welcome to theย Colorado River Research Groupโ€™s (CRRG)ย inaugural Colorado River Insights report. This publication marks a new (and still evolving) direction for the CRRG, transitioning away from the group-authored policy briefs of the past to more personal โ€œIndividual Submissionsโ€ that allow members to be more focused, direct and sometimes prescriptive than in the past efforts authored jointly and requiring unanimous consent. While each of the Individual Submissions (i.e., Chapters) that follows is unique in structure and tone and detail, each member was given the same charge: to speak directly about issues on the river where they have been directing much of their current focus, and where feasible, to identify a path forward on those issues. Given this approach, each Individual Submission is truly individualโ€”or, in several cases, the product of small groupsโ€”and thus should not be attributed to the entire body, although in practice there is usually very little internal conflict on any of the major themes featured throughout these pages. One byproduct of this approach is that it shines a light on some of the CRRGโ€™s most glaring holes in terms of disciplines and substantive expertise, helping to steer us to new potential members (and guest contributors) and, perhaps, new approaches. Unless or until that happens, we readily acknowledge that our collective snapshot of current and emerging basin issues is far from comprehensive. But how could it be? Thatโ€™s an impossible standard for a river as vast in size, importance and complexity as the Colorado.

We are hopeful that this new approach can be helpful in better funneling the knowledge emerging from the research community into the hands of decision-makers, journalists, NGOs, water users, and other concerned parties in a more hands-on position to implement the changes needed to restore the economic and environmental sustainability of the River. Clearly, we are in an era screaming for new ideas and new approaches; the status quo isnโ€™t working. โ€” Doug Kenney, CRRG Chair

On President Trump’s arroyo-phobic Clean Water Act rule: Plus: Congress kills another RMP, sows chaos; President Trump endangers Endangered Species Act — Jonathan P. Thompson (LandDesk.org)

November 25, 2025

The News: The Trump administration last week weighed in on the 53-year battle over what waterways are covered by the 1972 Clean Water Act โ€” with a draft rule that would narrow the definition of โ€œWaters of the United States,โ€ or WOTUS. The rule would effectively remove federal CWA protections from hundreds of arroyos, rivers, and ephemeral streams in the Southwest, giving developers industries more latitude to alter or pollute those waterways. The public has until Jan. 5 to submit comments.

The Context: For years, the Environmental Protection Agency and Army Corps of Engineersโ€”the agencies charged with enforcing the CWAโ€”considered WOTUS to include everything from arroyos to prairie potholes to sloughs to mudflats, so long as the destruction or degradation thereof might ultimately affect traditionally navigable waters or interstate commerce (which could include recreation, sightseeing, or wildlife watching). It was a broad definition that gave the agencies latitude to โ€œrestore and maintain the chemical, physical, and biological integrity of the Nationโ€™s waters,โ€ as Congress mandated when creating the law in 1972.

Developers and property rights ideologues pushed back on this definition, saying it was too broad and therefore gave the feds too much power to curb pollution or restrict development. The issue ended up in the courts and, ultimately, to the U.S. Supreme Court.

The waters were muddied, so to speak, by the 2006 Supreme Court split decision on the Rapanos case. The late Justice Antonin Scalia wrote what would become the right-wingโ€™s preferred definition of waters of the U.S. He argued that they should include only โ€œrelatively permanent, standing or continuously flowing bodies of water โ€ฆ described in ordinary parlance as streams[,] โ€ฆ oceans, rivers, [and] lakes.โ€ Scaliaโ€™s definition emphatically excluded โ€œephemeral streamsโ€ and โ€œdry arroyos in the middle of the desert.โ€ Justice Anthony Kennedy disputed Scalia, saying instead the CWA should extend to any stream or body of water with a โ€œsignificant nexusโ€ to navigable waters, determined by a wetlandโ€™s or waterwayโ€™s status as an โ€œintegral part of the aquatic environment.โ€

Then, in 2023, in its ruling on the Sackett case, the SCOTUS majority deferred to Scaliaโ€™s Rapanos definition, writing: โ€œโ€ฆ we conclude that the Rapanos plurality was correct: the CWAโ€™s use of โ€˜watersโ€™ encompasses โ€˜only those relatively permanent, standing or continuously flowing bodies of water forming geographical features that are described in ordinary parlance as streams oceans, rivers and lakes.โ€™โ€

Itโ€™s up to the relevant agencies to translate these rulings into actual rules, often adding their own ideological twists. The W. Bush, Obama, and Trump I administrations issued their own post-Rapanos definitions of WOTUS, Biden weighed in post-Sackett, now Trump II is submitting its own set of industry-friendly, deregulatory definitions.

The EPAโ€™s proposed definition of โ€˜โ€˜waters of the United Statesโ€™โ€™ would include:

โ€œRelatively permanent,โ€ under the new rule, would mean

And then thereโ€™s this weird and vague, yet critical, term, โ€œwet season,โ€ which the rule defines as:

Sometimes you have to wonder whether the bureaucrats who come up with these things have ever even been to the Western U.S., particularly the arid Southwest.

The โ€œrelatively permanentโ€ requirement clearly excludes thousands of arroyos, ephemeral streams, washes, gullies, and even rios and rivers โ€” from the Santa Cruz to the Rillito to the Santa Fe to the Puerco and the Dirty Devil โ€” from CWA jurisdiction. Indeed, it leaves huge swaths of the Southwest without Clean Water Act protections, and at the mercy of respective states or counties. A 2008 EPA study estimates that ephemeral and intermittent streams make up 59% of all of the waterways in the U.S. (excluding Alaska) and over 81% in the arid and semi-arid Southwest (AZ, NM, UT, CO, CA).

Source: U.S. EPA.

The ecological benefits of ephemeral streams are obvious to any Western wanderer who happens to venture down a seemingly dry and barren arroyo bed, where they may find cool air, the smell of water even on the hottest day, tiny tracks of animals seeking sanctuary from the sun, the lascivous bloom of a datura, and cottonwoods and even willows miles and miles away from any โ€œrelatively permanentโ€ water source. And if thatโ€™s not enough, then consider that peer-reviewed research has found that these same ephemeral streams are major contributors to the water quantity and quality of the entire river drainage network of which they are a part.

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

A 2024 study by Craig Brinkerhoff et al concludes: โ€œThis ephemeral influence directly implicates downstream water quality standards: Excluding ephemeral streams from coverage under the CWA would substantially narrow the extent of federal authority to regulate water quality in the United States.โ€

While the administration was looking to provide โ€œclarity,โ€ the โ€œwet seasonโ€ provision does exactly the opposite, especially when one tries to apply it to the desert Southwest. If southern Arizona has a wet season, wouldnโ€™t it be the days and weeks of the late summer monsoon? Many arroyos do run continuously during a good monsoon season, even if it is only for two or three weeks. So would that put them back under CWA jurisdiction?

How these proposed changes would play out on the ground is a bit of a puzzle โ€” especially given the โ€œwet seasonโ€ ambiguity. But what is clear is that developers of big housing projects in the desert outside Phoenix or Las Vegas or Tucson, for example, would be allowed to fill in or build roads through arroyos and washes without obtaining a federal CWA permit from the Army Corps of Engineers. That would leave it to the state and county to implement their own, similar, permitting systems if they chose to do so.

As one might expect, the energy industry, developers, ranchers, and farmers generally support the changes, since it will eliminate some of the red tape that tangles up and delays projects.

โ€œFor U.S. oil and natural gas operators, this is a game-changer,โ€ wrote the head of a Texas petroleum industry group in the Odessa American. โ€œPicture the Permian Basin or Bakken Formation: vast swaths dotted with intermittent draws and playas that previous rules treated like sacred rivers, triggering Section 404 permits under the U.S. Army Corps that could drag on for years and cost millions in mitigation. Now, with ephemeral features sidelined and groundwater off-limits, operators can overcome those hurdles for well pads, access roads, and seismic surveys.โ€

If you live in the West, you probably live near at least one of the ephemeral streams that would lose federal protections under these new definitions. You might want to go walk up it sometime soon before it goes away.

News Roundup: Arroyos on trial; Superstition Vistas; Lake Powell bridge — Jonathan P. Thompson

๐ŸŒต Public Lands ๐ŸŒฒ

Congressional Republicans have apparently decided that the best way to turn over public lands to the extractive industries is to do away with the plans guiding management of those lands. Earlier this year, Congress revoked three Bureau of Land Management resource management plans in Montana, North Dakota, and Alaska. Now, theyโ€™ve done the same for the RMP for the BLMโ€™s Buffalo Field Office in Wyoming, which covers a good portion of the coal-rich Powder River Basin.

These mark the first times ever that the Congressional Review Act, which is intended to give Congress the power to review and possibly revoke recently implemented administrative rules, has been used in this manner. Thatโ€™s in part because RMPs have not been considered โ€œrulesโ€ in the past, meaning they are not subject to congressional review.

Resource Management Plans provide a framework for managing large swaths of land and authorize the BLM to permit mining, drilling, grazing, and other activities. They endeavor to balance the agencyโ€™s multiple-use mandate with environmental protections, guiding resource extraction and development away from sensitive areas and toward more appropriate ones, for example. They can take years to develop, and incorporate science, legal considerations, court orders, tribal consultation, and input from local officials and the general public.

And then, with just a few hours of debate and no opportunity for public input, Congress can toss the whole thing into the can. 

In this case, the main target was a provision of the Biden-era RMP that halted new coal leasing on that swath of public land. While the moratorium was celebrated by environmentalists and panned by fossil fuel lovers when it was implemented late last year, it was largely symbolic, since existing leases contain enough coal to meet demand at least until 2040. So revoking the ban similarly wonโ€™t lead to any new mining anytime soon, nor are resulting lease sales likely to fetch much industry interest or acceptable bids. 

But in their haste to scrap the ban, Congress also may have taken away the BLMโ€™s power to issue new leases altogether โ€” not just for coal, but for oil and gas drilling, grazing, or any other use. And not just for the Buffalo Field Office, either. This is a bit wonky, but basically it goes like this:

  • By applying the CRA to RMPs, Congress is saying that RMPs are โ€œrules.โ€
  • According to the CRA, rules must be submitted to Congress before they can take effect.
  • No RMP that has been implemented since 1996 has been submitted to Congress.
  • Therefore, no post-1996 RMP has legally taken effect, making it invalid.
  • The Federal Land Policy Management Act says the BLM can only issue permits, leases, rights of way, and other authorizations โ€œin accordance withโ€ a valid land use plan, or RMP.
  • Therefore all permits, leases, ROWs, and other authorizations issued under post-1996 RMPs โ€” including over 5,000 oil and gas leases, and hundreds more coming up for auction in the near future โ€” are invalid.

This summer, 31 law professors and public land experts called on Congress to refrain from using the CRA to revoke RMPs. โ€œThe resulting uncertainty could trigger an endless cycle of litigation,โ€ they wrote, โ€œeffectively freezing the ability of the BLM and other agencies to manage public lands for years, if not decades to come.โ€

Just last week, a group of conservation organization legal analysts expanded on the potential for chaos, and called on the BLM to pause new leasing and address the โ€œpotential legal deficienciesโ€ of oil and gas leases covering some 4 million acres that were issued under now potentially invalid RMPs. The agency should not issue drilling permits for those leases, the analysts wrote, and it should consider canceling the leases.

Somehow, I donโ€™t think the BLM under the current administration is going to follow that suggestion. Given its track record, it seems more likely that the agency will see the sudden lack of valid RMPs as an open gate through which it can ferry its pro-extractive agenda. This one is almost sure to end up in court.

๐Ÿฆซ Wildlife Watch ๐Ÿฆ…

The Trump administration is proposing new regulations that would dial back Endangered Species Act protections and weaken the landmark law to โ€œstrengthen American energy independence,โ€ according to an Interior Department news release.

The new rules would:

  • Make it more difficult for the U.S. Fish & Wildlife Service to designate critical habitat in areas that are not currently occupied by an endangered species โ€” likely because they were extirpated from the area โ€” but that are essential for the conservation of that species. This would make recovering an endangered species that much more difficult.
  • Remove a rule that extends ESA protections to species that are listed as โ€œthreatened,โ€ which is one step away from โ€œendangered.โ€ This would potentially remove protections for species such as the marbled murrelet, vernal pool fairy shrimp, western snowy plover, Gunnison sage grouse, northern sea otter, and many others.
  • Direct agencies to give economic impacts greater weight when deciding whether to extend ESA protections to a species. This could have potentially pushed the feds to, say, back off on listing the Tiehmโ€™s buckwheat under the ESA, because doing so would potentially restrict or nix a proposed lithium mine in its only known habitat.
  • Make it more difficult for the U.S. Fish & Wildlife Service to designate critical habitat in areas that are not currently occupied by an endangered species โ€” likely because they were extirpated from the area โ€” but that are essential for the conservation of that species.

โ€œThis plan hacks apart the Endangered Species Act and creates a blueprint for the extinction for some of Americaโ€™s most beloved wildlife,โ€ said Stephanie Kurose, deputy director of government affairs at the Center for Biological Diversity, in a written statement.

Click the link to read the release on the Colorado River District website (Lindsay DeFrates):

The acceptance of the Shoshone water rights marks a landmark partnership between the State of Colorado and the western slope.

Today, Wednesday, November 19, the Colorado Water Conservation Board (CWCB) voted unanimously to accept the joint offer by the Colorado River District and Public Service Company of Colorado (PSCo) of a perpetual interest in the use of the Shoshone Water Rights for instream flow purposes.

Once confirmed by water court, this acquisition will create the largest environmental water right in the stateโ€™s history and permanently protect the historic flow of the Colorado River.

โ€œThe importance of todayโ€™s vote cannot be overstated as a legacy decision for Colorado water and the western slope. It secures an essential foundation for the health of the Colorado River and the communities it sustains,โ€ said Andy Mueller, General Manager of the Colorado River District. โ€œWe continue to be impressed by, and thankful for, the broad coalition of voices that have come together in support of protecting the Shoshone Water Rights. Without them, we would not have been able to meet this historic milestone.โ€

โ€œToday, the CWCB demonstrated its deep commitment to Coloradoโ€™s water security by taking bold, permanent action to protect our namesake river. We are proud to stand with the State and with our many partners across the West Slope in securing these flows for the benefit of all Coloradans,โ€ said Sen. Marc Catlin, president of the Colorado River District Board of Directors. โ€œThis agreement strengthens water security for hundreds of communities within our state and represents a proactive, durable solution for the 40 million people who rely on the Colorado River downstream. The Shoshone Water Rights Preservation Project keeps the river as whole as possible, keeping water in its natural basin and safeguarding this lifeline for generations to come.โ€

The boardโ€™s decision today was the final step in the instream flow acquisition process that began with the formal offer in May 2025. Following a contested hearing in September โ€“ requested by four Front Range water entities โ€“ the Colorado River District and PSCo granted the CWCB additional time to continue deliberations and fully consider the historic proposal and partnership at their November meeting.

35 entities filed for party status in support of the Shoshone Water Rights ISF proposal. These include West Slope towns and counties, water districts, as well as local and regional non-profits. Over 400 positive public comments were also submitted over the summer.

โ€œTodayโ€™s decision by the CWCB is a tremendous step forward for the health of the Colorado River and the communities that rely on it,โ€ said Senator Dylan Roberts. โ€œThe Shoshone Permanency effort reflects years of collaboration and a shared commitment to protecting our headwaters, and Iโ€™m grateful to all the partners who brought us to this point. There is still important work ahead, but this vote positions Colorado to take advantage of the years of effort and protects these flows for generations to come.โ€

โ€œThe Shoshone water rights are a lifeline for western Colorado,โ€ said Mesa County Commissioner Bobbie Daniel. โ€œOur farmers, ranchers, recreation enthusiasts, and energy producers depend on this water, and we are proud to see the CWCB support this project. These flows are the future of our families and communities, and now, more than ever, it is critical that we are doing everything we can to protect them.โ€

Xcel Energy provided the following statement: โ€œXcel Energy recognizes the significant collaboration and effort that brought us to todayโ€™s decision by the Colorado Water Conservation Board. We appreciate the engagement from all parties throughout this process and look forward to continuing the work ahead. This agreement represents an important step in ensuring reliable, clean energy for the communities we serve while supporting responsible stewardship of Coloradoโ€™s water resources.โ€

The CWCB also issued their own press release, which is available on their website here: https://cwcb.colorado.gov/category/news-articles

In December 2023, the Colorado River District and Public Service Company of Colorado (PSCo), a subsidiary of Xcel Energy, entered into a $99 million Purchase and Sale Agreement (PSA) to acquire the historic Shoshone Water Rights, senior (1902) and junior (1929) non-consumptive rights that stabilize flows on the upper Colorado River. The PSA is the product of decades of work by the statewide Shoshone Water Right Preservation Coalition.

To close the transaction, the PSA requires four conditions: execution of an Instream Flow Agreement with the CWCB (approved today), receipt of a water court decree approving the change of water rights, securing commitment of full project funding ($99 million), and approval from the Colorado Public Utilities Commission. So far, the Shoshone Water Rights Coalition has secured commitments of over $57 million from West Slope entities, the State of Colorado, and the Colorado River Districtโ€™s Community Funding Partnership. The Bureau of Reclamation awarded the project $40 million through the Inflation Reduction Act Funds in January 2025 โ€“ those funds remain under review by the current administration.

Todayโ€™s CWCB decision fulfills that critical Instream Flow Agreement requirement, moving the project significantly closer to final completion and the permanent protection of the Shoshone flows.  The River District, PSCo, and the CWCB will be initiating the water court process to add instream flow use to the Shoshone water rights. The River District and its full coalition of supporters will also be turning their focus on fully securing the previously awarded federal funds.

In a historic move Wednesday evening, the state water board voted unanimously to accept water rights tied to the Shoshone hydropower plant, a major step toward securing those flows in perpetuity for the Western Slope.

The Colorado Water Conservation Board said the Shoshone water rights, which are some of the oldest and most powerful on the mainstem of the Colorado River, can be used to benefit the environment. 

โ€œThe Shoshone acquisition makes a lot of sense to me, and Iโ€™m very proud to be a part of the work that everybodyโ€™s put into it,โ€ said Mike Camblin, who represents the Yampa, White and Green river basins on the CWCB. โ€œI hope that our children and our grandchildren look back and realize we made the right decision on this.โ€

The Glenwood Springs-based Colorado River Water Conservation District plans to purchase the Shoshone water rights for $99 million from Xcel Energy, but the district first needed the approval of the CWCB, which is the only entity in the state allowed to hold instream-flow water rights to benefit the environment. Because the water is returned to the river after it runs through the hydroplantโ€™s turbines, downstream cities, irrigators, recreators and the environment all benefit.

River District General Manager Andy Mueller called it a fantastic day in Colorado history. 

โ€œI think that was the right decision for the Colorado River and the right decision for our whole state,โ€ Mueller said. โ€œI think the state for generations to come, centuries in the future will benefit from having that water in the Colorado River.โ€

Importantly, the instream-flow agreement approved by the board says that the Western Slope, along with the CWCB, will retain some control over exercising the rights. The River District and its constituents drew a hard line in the sand regarding this point and said they would walk away from the deal if they had to cede control solely to the CWCB.

Though not totally unprecedented, co-management is a departure from the norm, as the CWCB has never shared management of an instream-flow water right this large or this powerful with another entity. 

In attendance at Wednesdayโ€™s CWCB meeting in Golden were representatives of ditch companies, elected officials and water managers from across the River Districtโ€™s 15-county area. Some of the attendees said during their public comments that if the River District didnโ€™t retain some control over the water rights, they would pull their funding and withdraw their support from the Shoshone campaign. 

Mesa County Commissioner Bobbie Daniel said the joint-management proposal is a safeguard that ensures that Western Slope interests are not pushed aside. Mesa County has committed $1 million toward the purchase of the water rights.

โ€œThe Shoshone call is one of the great stabilizing forces on the river, a heartbeat that has kept our valley farms alive, our communities whole and our economy steady, even in lean years,โ€ Daniel said. โ€œIf a joint management is not adopted, Mesa County will withdraw its support for this acquisition. Itโ€™s not out of anger or politics, but because anything less would fail the people that we serve.โ€

Blow to the Front Range

The CWCBโ€™s decision was a blow to Front Range water providers, who objected to the River Districtโ€™s having a say over how to manage the water rights, even though they supported the overall goal of protecting flows for the environment. Denver Water, Northern Water, Aurora Water and Colorado Springs Utilities argued that the CWCB has exclusive authority over the rights, according to state statute. 

Critically, because the Shoshone plantโ€™s water rights โ€” one that dates to 1902 for 1,250 cubic feet per second and another that dates to 1929 for 158 cfs โ€” are senior to many other water users, they have the ability to command the flows of the Colorado River and its tributaries upstream all the way to the headwaters. This means that the owners of the rights can โ€œcall outโ€ junior Front Range water providers with younger water rights that take water across the Continental Divide via transmountain diversions and force them to cut back. 

The fact that Front Range water providers take about 500,000 acre-feet annually from the headwaters of the Colorado River is a sore spot for many on the Western Slope, who feel the growth of Front Range cities has come at their expense. These transmountain diversions can leave Western Slope streams depleted. 

The Shoshone call pulls water west much of the time. But the Front Range parties wanted assurances that during extreme droughts or emergency situations, the call would be โ€œrelaxed,โ€ allowing them to take more water to their citiesโ€™ millions of customers. 

Alex Davis, assistant general manager with Aurora Water, said the CWCB should retain the ability to relax the call as a โ€œbackstopโ€ under extremely rare circumstances. 

โ€œIt is asking that in those emergency situations, the board has the ability to step in and say: Weโ€™re going to do what we think is best for the state of Colorado,โ€ Davis said.

The agreement approved by the board lays out a collaborative process to consider a call relaxation, with a stakeholder panel of water managers from both sides of the divide. The specific wording of this agreement was hashed out during Wednesdayโ€™s meeting, with lawyers representing the CWCB and River District conferencing to tweak language and make edits.

The CWCB had been set to decide on the Shoshone rights at its meeting in September, but the River District granted an eleventh-hour 60-day extension so they could address issues raised by the board and try to negotiate a consensus with the Front Range parties. 

Despite all the detailed arguments laid out by the parties, thousands of pages of technical and legal documents, and hours of testimony and public comment over the September and November CWCB meetings, the boardโ€™s scope of decisionmaking remained narrow: Should the CWCB accept a perpetual interest in the Shoshone water rights and will these rights preserve the natural environment to a reasonable degree? 

In the end, the board decided yes, and also determined that it did, in fact, have the authority to allow the River District to co-manage the Shoshone water rights alongside it.

โ€œI really think itโ€™s pretty incredible that thereโ€™s no objection to the environmental aspects of this flow and the purpose of this water right for environmental purposes,โ€ said CWCB Director Taylor Hawes, who represents the mainstem of the Colorado River where the Shoshone plant is located. โ€œ(The River District is) donating that water right. It seems like they should have a say. And while I realize this case is unique, I donโ€™t see anything in the statute or the rules that prohibits us from doing this.โ€

But the fight to keep Shoshone flowing west is not over for the River District. The CWCB, River District and the water rightsโ€™ current owner, Xcel, now plan to file a joint application in water court to make the deal official by adding the instream-flow use to the water rights. 

The water court process will decide another contentious issue that is sure to again highlight disagreement between the Western Slope and Front Range as they compete for the stateโ€™s dwindling water resources: precisely how much water is associated with the water rights, a number based on the plantโ€™s past use.

โ€œI also very much understand the concerns of both sides of the divide in not wanting the other side to have a windfall,โ€ Hawes said. โ€œThat has been kind of the heart of all of this. And I hope we can all trust that the water courtโ€™s process will give us a result where we donโ€™t have to worry about that. Everyoneโ€™s concerns will be addressed in that process.โ€

November 20, 2025

 In a momentous decision for the Western Slope, state water officials unanimously approved a controversial proposal to use two coveted Colorado River water rights to help the river itself.

Members of the Colorado Water Conservation Board voted to accept water rights tied to Shoshone Power Plant into its Instream Flow Program, which aims to keep water in streams to help the environment.

The decision Wednesday is a historic step forward in western Coloradoโ€™s yearslong effort to secure the $99 million rights permanently. But some Front Range water providers pushed back during the hearings, worried that the deal could hamper their ability to manage the water supply for millions of Colorado customers.

For the state, the two water rights will be a crown jewel in its five-decade environmental effort to help river ecosystems. Itโ€™s one of several steps in the agreement process, and it could take years before the river feels that environmental benefit.

โ€œThe Shoshone acquisition makes a lot of sense to me, and Iโ€™m very proud of the work that everybodyโ€™s put into it,โ€ said Mike Camblin, who represents the Yampa and White river basins on the Colorado Water Conservation Board. โ€œI hope that our children and our grandchildren look back at this and realize we made the right decision.โ€

Over 100 Colorado water professionals and community members gathered in Golden for a six-hour hearing about the environmental proposal, brought forward by the Colorado River District, which represents 15 counties on the Western Slope.

The small hydropower plant off Interstate 70 near Glenwood Springs has used Colorado River water to generate electricity for over a century. But the aging facility has a history of maintenance issues, and Western Slope water watchers have long worried about what happens to the rights if it were to shut down for good.

The Colorado River District wants to add the environmental use as part of a larger plan to maintain the โ€œstatus quoโ€ flow of water past the power plant, regardless of how long it remains in operation.

Western Slope communities, farms, ranches, endangered species programs and recreational industries have become dependent on those flows over the decades and broadly supported the districtโ€™s proposal.

โ€œIโ€™m good. Iโ€™m much more relaxed now,โ€ Andy Mueller, the districtโ€™s general manager, said after the vote Wednesday. โ€œThe reality is, we have set up our state, through this instream flow agreement, for success for centuries on the Colorado River.โ€

Some powerhouses in Colorado water support the general permanency effort but oppose parts of the agreement. Northern Water, Colorado Springs Utilities, Denver Water and Aurora Water said the proposal would give the Colorado River District too much sway in decisions that would impact them.

These water managers and providers are responsible for delivering reliable water to millions of people, businesses, farms and ranches across the Front Range. Any change to Shoshoneโ€™s water rights could have ripple effects that would affect over 10,000 upstream water rights, including some held by Front Range water groups.

The negotiations over the agreement continued throughout the meeting. Board members had about 24 hours to review a stack of documents marked with tweaked phrasing and proposed edits.

Both sides are concerned that the other could get a water windfall through the agreement, said Taylor Hawes, who represents the Colorado River on the board. Those concerns can be addressed in the next step of the process: Water Court.

โ€œThat has been the heart of all of this,โ€ Hawes said. โ€œI hope we can all trust that the water courtโ€™s process will give us a result where we donโ€™t have to worry about that.โ€

Who will control the flow of water?

The Colorado Water Conservation Board was supposed to make its final ruling on the environmental use proposal in September. Then Public Service Company of Colorado, the Xcel subsidiary that owns the rights, and the Colorado River District filed an 11th-hour extension to delay until the meeting Wednesday.

Thatโ€™s, in part, because they needed more time to address a central conflict in the agreement: Who makes the final decisions when managing the powerful rights?

Shoshone uses two rights to access the Colorado River: one for 1,250 cubic feet per second that dates back to 1905, and a right to 158 cubic feet per second that dates back to 1940.

They amount to a big chunk of water. Plus, these rights can be used year-round, and they supersede more recent, junior rights like several held by Front Range water providers.

Under the agreement, the water rights will be co-managed by the Colorado River District and the Colorado Water Conservation Board.

Western Slope parties were adamant about this. Several speakers said they would pull their funding, and there would be no agreement if the River District did not have a say in how the water rights would be used.

โ€œIf joint management is not adopted, Mesa County will withdraw its support for this acquisition,โ€ Bobbie Daniel, Mesa County Commissioner, said. โ€œItโ€™s not out of anger or politics, but because anything less would fail the people that we serve.โ€

The Front Range groups said the state should make the final decision if Colorado River District staff and CWCB staff disagreed over how to manage the water rights. They argued the board has exclusive authority under state law.

Alex Davis with Aurora Water said her team was pushing for a โ€œhammerโ€ โ€” an entity, preferably the state, that could force water providers on either side of the Continental Divide to come to the negotiating table or that could make the final decision, especially in times of crisis.

Aurora pulls about 25,000 acre-feet of water from the Western Slope, through mountain tunnels and into its water system each year, she said. (An acre-foot of water is about what two to three  households use in a year.) But when Shoshone is using its 1905 water right to its fullest, nearly all of Auroraโ€™s transmountain diversions are turned down or turned off.

The city might want to ask Shoshone to use less water to provide some relief in an emergency. The agreement seems to give the Colorado River District a veto, Davis said.

โ€œBy the River District having that decision-making power, it may lead to less incentive on the West Slope side in those emergency situations,โ€ Davis said in an interview with The Sun. โ€œThatโ€™s what we were worried about.โ€

Colorado Water Conservation Board members decided to continue with the co-management approach, saying they were not giving up authority or working outside of state statute by doing so.

Mueller said the agreement is a win for the river and the entire state. It will protect endangered fish and a critical 15-mile stretch of habitat near Grand Junction. It includes exceptions that will protect cities during multi-year droughts and emergency situations, he said.

โ€œThe CWCB and the River District can act together for the best interest of the state,โ€ Mueller said in an interview. โ€œWeโ€™ll have to earn some trust in that realm over the years, but Iโ€™m quite convinced we can do it.โ€

About that $99 million billโ€ฆ

The Colorado River District has entered into a $99 million agreement with Xcel Energy to buy the Shoshone water rights.

The stateโ€™s decision to accept Shoshoneโ€™s water rights into its environmental program met one of four key closing conditions of that purchase agreement, Amy Moyer, chief of strategy for the Colorado River District, said.

The deal still needs approval by Coloradoโ€™s Public Utilities Commission. Itโ€™ll be weighed in Water Court, where Western Slope and Front Range representatives will wade through another thorny issue: What has Shoshoneโ€™s โ€œstatus quoโ€ water use been over the last century?

The Colorado River District and its Western Slope supporters need to pay up. Although theyโ€™ve pulled together over half the asking price, theyโ€™re still waiting to hear about whether a request for federal funding will be approved.

If the deal passes those hurdles, then the resulting purchase and instream flow agreement will go on indefinitely. It will provide more predictability for water users across the state, and it will continue to factor into how Colorado communities grow, officials said Wednesday. โ€œWeโ€™re making some very far-reaching decisions here,โ€ Nathan Coombs, the boardโ€™s Rio Grande Basin representative, said. โ€œI still think this is the right choice right now with the information we have.โ€

November 19, 2025, Golden, CO โ€“ This evening, the Colorado Water Conservation Board (CWCB) voted to approve the long-anticipated Shoshone water rights acquisition, to secure two water rights associated with the Shoshone Power Plant, including one of the stateโ€™s most significant Colorado River water rights, for permanent instream flow protection. The vote launches the next phase of the process, including water court, and begins the work of preserving and improving the 2.4-mile reach of the Colorado River between the Shoshone Power Plant Diversion Dam and Tunnel and the Shoshone Power Plant Discharge Outlets.

โ€œSecuring one of the stateโ€™s most significant Colorado River water rights for permanent instream flow protection is a momentous achievement,โ€ said Lauren Ris, CWCB Director. โ€œThis outcome reflects a tremendous amount of work, from extensive technical analysis and stakeholder engagement to thorough regulatory review and legal preparation. This careful evaluation ensures our investment delivers long-term benefits for the river and for Coloradans.โ€

The agreement passed on a unanimous vote, with two directors recused. The decision follows the Colorado River Districtโ€™s authorization of an extension from the September hearing to the November Board meeting, allowing additional time for review of the information presented and continued efforts to achieve a negotiated resolution of contested issues. 

โ€œI want to thank all the people who have worked so hard to inform this decision for the Board and the diverse range of stakeholders who earnestly engaged,โ€ said Dan Gibbs, Executive Director, Colorado Department of Natural Resources. “Acquiring the Shoshone water rights for instream flow use is a once-in-a-lifetime opportunity to preserve and improve the natural environment of the Colorado River. But I also want to stress that the state is committed to ensuring that the historical use of the water rights is maintained at the status quo and we are committed to participating in any process to settle and resolve these issues for all water users. I am confident in our ability as a state and as a water community to come together in a way that is beneficial to all.โ€

Over the last two months, the CWCB and the Colorado River District met with Front Range entities and other interested parties to work toward resolving the issues raised at the September hearing. The next step in the process is the filing of an application in water court, for approval of the change of water rights to include instream flow use in a way that will not cause injury to decreed water rights.

This milestone follows significant commitments from the Colorado River District, local partners, and the CWCB, including the Stateโ€™s $20 million Projects Bill contribution, to secure the long-term future of the Shoshone water rights.
