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.

Let’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 “normal,” and wrote it into law. When the water showed up, we spent it. When it didn’t, we blamed the weather, climate change, or each other—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. We wanted them to be savings accounts, when in reality we treated them like credit cards—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 nation’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 elsewhere—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 creativity—but because we are still taking more water out of the system than the river is putting in.

Reservoirs don’t lie.They are the silent accountants of what we actually do, not what we say we’re doing.

Here in Colorado, when the river runs low, the impacts are immediate. We don’t have a giant reservoir upstream to hide behind. Shortages here are hydrologic. They are real. Farmers fallow fields. Municipalities restrict use. Communities adapt—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 matters—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 river–-a river of the past. The drought contingency plans were emergency patches—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 don’t fix holes in reservoirs. And the idea that we can simply extend these frameworks or merely modify them —while Powell and Mead hover near critical elevations—is not leadership. It’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 problem–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 don’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 isn’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 “come to the table,” as if we’ve been absent. But we’ve been here the entire time—bringing hydrology, realism, and a simple message: if reductions aren’t real, reservoirs won’t recover. It is telling that what some refer to as an extreme negotiating position is based solely on the simple facts of hydrology—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 use—not in proportion to who can avoid the truth the longest.

Because if we don’t choose how to live within the river’s limits, the river will choose for us. And it will not be gentle.

This is not a call for conflict.

It’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 us—clearly and without spin—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 have—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.

That’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.

“It depends on the day that you ask me,” Colorado’s negotiator, Becky Mitchell, said Tuesday when asked by KUNC News if she thinks the states are heading toward a court battle. “But 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. There’s some things that we can’t give on.”

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,” Mitchell said. “And I think asking people to guarantee something that cannot be guaranteed is a recipe that cannot get to success.”

The lower basin states of California, Arizona and Nevada are proposing to cut 1.5 million acre feet of their water use. They’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.

“It’s tough to say I’m looking forward to it, because that would be a lie,” Mitchell told a large crowd Wednesday at a water conference in Aurora.

Her speech was fiery at times.

“Operations must be supply based, not demand based, not entitlement justified, and not built on a hope that the next big year will save us,” she said. “That harm will be irreversible, because the Colorado River is not too big to fail.”

As Mitchell was addressing the water conference in a hotel ballroom, California’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.

“It’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 “leaning in” and becoming more involved in the negotiations by offering potential options.

Hamby called the feds’ ideas helpful.

“Continued back and forth between the basins haven’t really been moving the ball forward,” he said. “The administrations…have 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.”

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

“It’s going to take everyone chipping in and making the necessary (water) reductions to balance the supply with the demand we have moving forward,” 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 must 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 “Assigned Water” – giving users the ability to store conserved water earmarked for their own future use.

Originally developed as “Intentionally Created Surplus” 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 agencies’ use, sitting outside of the priority system through which the rest of the Colorado River’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 “private water,” 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 “use it or lose it” 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 “system assessment” for the privilege. This mechanism would credit their earmarked storage account for a portion of the conserved water while converting the remainder to “System Water,” 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 Basin’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 BASIN’S TRAGEDY OF THE COMMONS

For more than a century of development, Colorado River governance has lived under a tension between individual communities’ 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: Water diverted within the U.S. generally under the prior appropriation system of water allocation.
  • Mexican Water: 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: 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 which 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 Secretary’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, 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 Project’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 “no action” alternative required by law, three alternatives that would require agreements among the basin states, and one “no deal” 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 “no deal” 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 “no deal” alternative would result in a crushing blow to Central Arizona’s water supply, including tribal water supplies. Millions of Arizona residents would be negatively affected – including those in the fifth largest city in the United States, as would several of the nation’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 “no deal” 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.

Here’s what CAWCD’s Board members have to say about the DEIS:

“Each alternative put forward places the risk of a dwindling Colorado River on the Lower Basin – none of them are good for Arizona and certainly not for Central Arizona Project. In the Lower Basin, we’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. That’s not acceptable to CAP whose millions of water users and billions in industrial investments will bear the brunt of these devastating alternatives.”  – Terry Goddard, CAWCD Board President

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

“Arizonans have been smart water stewards, conserving water for decades in our desert environment. What’s more, we’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. We’ve done our part and it’s so disappointing to see alternatives that make Arizona bear the burden for all Colorado River users.”   – Karen Cesare, CAWCD Board Secretary

“Pinal 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. We’ve already felt a great deal of pain and these alternatives would be rubbing salt in the wound and would continue to devastate Arizona.”  – Stephen Miller, CAWCD Board Member, Pinal County

“CAP 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 CAP’s water users – cities, industries and tribes.”  – Justin Manuel, CAWCD Board Member, Pima County and member of Tohono O’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.

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.

It’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.

“We got tired of each other,” Utah’s negotiator, Gene Shawcroft, said Tuesday at a public board meeting, days after the meeting ended. “And 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.”

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 “hopes to attend this meeting if it works for the other Governors.”

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.

“The 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,” 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 KUNC’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 ‘normalize’ 1.48 million acre feet of water shortages each year in the lower basin states.

“And this would just basically say every year, that’s a given,” Berggren said.

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

Berggren said this option “does not do enough.”

“There’s many years where the system crashes,” he said.

A crash means Lake Powell and Lake Mead reach deadpool, a scenario where they’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 ‘a little more innovative.’

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.

“It’s water security, because if we can save water today, we’ll put it into storage and we can withdraw it later when we need it,” 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 “seeks 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 reservoirs’ abilities to support the Basin.”

No action

This plan might sound like the path with the least impact, but that’s far from the case.

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

“It basically says Reclamation will shoot to release 8.23 million acre feet of water from Powell, and that’s kind of it,” Berggren said. “Not 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.”

According to the Interior Department, “there would be no new mechanisms to proactively conserve and store water in Lake Powell or Lake Mead.”

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 “designed to help stabilize system storage, incentive proactive water conservation, and extend the benefits of conservation and operational flexibility to a wide range of resources.”

It’s also designed to give dam operators more flexibility to respond to the impacts of climate change.

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 “climate response indicator” would be introduced to help decide how much water should be released from Lake Powell.

“If the last three years have been really dry or exceptionally dry, then you adjust your Lake Powell releases,” 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 KUNC’s Colorado River coverage.

Supply driven alternative

“All 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,” Berggren said. “You 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.”

He said the plan, which incorporates ideas from the states themselves, was nicknamed “the amicable divorce of the basins.”

“Because it was basically the upper basin will do its thing with Lake Powell and its upper basin reservoirs,” he said. “And then whatever gets released, lower basin deals with that, deals with Lake Mead, deals with lower basin shortages.”

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.

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 — 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 can’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 couldn’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 else’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 week’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 river’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 I’ll try to answer them soon. Also, I’ll be doing a host of data-driven, Colorado River-related dispatches in coming weeks to go over some of last year’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 isn’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 “call” 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: 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 “not cause the flow of the river at Lee Ferry to be depleted below an aggregate of 75 million acre-feet” 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 — compared to some 40 million users now. Source: USGS.
  • The Upper Basin divided its 7.5 MAF by percentage: 51.75% to Colorado; 11.25%to New Mexico; 23% to Utah; 14% to Wyoming (plus an additional 50,000 acre-feet for the portion of Arizona in the Upper Basin).
  • The Lower Basin allotted 4.4 MAF to California; 2.8 MAF to Arizona; .3 MAF to Nevada.
  • 20 million acre-feet: Presumed total annual natural flow of the river upon which the compact was based and which was considered “more than sufficient to water all lands now being irrigated and all lands which can be economically developed for forty years to come.”
  • 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 compact’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 “natural flow” 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 what’s to come, we could expect a relatively minuscule amount of water running through the Grand Canyon to the Lower Basin states.

Winters v. the United States: 1908 Supreme Court ruling establishing that when the federal government “reserved” 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 “beneficial use” at that time. Winters did not quantify the amount of water tribes were entitled to, except that it should be “sufficient … for irrigation purposes.”

  • 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 — 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 — 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: One of the early 20th century’s foremost authorities on the Colorado River, who warned the Colorado Compact signatories that their negotiations were based on overestimates of the river’s supply. In 1916, he wrote: “Evidently, the flow of the Colorado River and its tributaries is not sufficient to irrigate all the irrigable lands lying within the basin.” 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 didn’t heed his warning, even though he repeated it many times prior to the compact’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 dam’s penstocks. This is especially critical at Lake Powell because if water can’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 wouldn’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 River’s headwaters to the state’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 project’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 River’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 ‘Draft Environmental Impact Statement’ (DEIS) for ‘Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead.’

The five alternative ‘operational guidelines and strategies’ analyzed in this DEIS were announced back in the fall of 2024; the Bureau has spent the past year-plus examining their environmental impacts. I’m not going to go into their analyses right now; I’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 ‘No Action’ 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 – 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, I’ll go off again on what I hope might be at least a more interesting tangent, and maybe more creative – 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 ‘Romancing the River’ – ‘romance’ 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 – ‘your mission should you choose to accept it,’ as it was expressed in Mission Impossible and The Hobbit.

‘Romance’ 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 ‘romance of reclamation,’ observing that ‘a vein of romance runs through every form of human endeavor.’ 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 river’s greatest romantics, John Wesley Powell, on Powell’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 ‘romance’ 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 ‘romancing the river.’ In an observation about a small central Arizona tributary of the Colorado River, ‘the fabled Hassayampa,’ she reports an unattributed legend: ‘If any drink [of its waters], they can no more see fact as naked fact, but all radiant with the color of romance.’

That could be construed into a kind of spectrum, the ‘naked facts’ of any situation at one end, the ‘radiant colors of romance’ dressing up the naked facts at the other end. The discipline of science is to stay as close to the ‘naked facts’ 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 – 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 – partially, probably, because college science was a little too tame. One of his early ‘field trips’ was a solo trip the length of the Mississippi River in a rowboat. Another was a four-month walk across the ‘Old Northwest Territory’ state of Wisconsin. Both of those trips pretty unquestionably fall more into the category of ‘romantic adventures’ than ‘scientific expeditions.’

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 ‘another America,’ a nation of small decentralized and mostly locally-sufficient communities of farm families – 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 – 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 Powell’s scientific grounding with getting him through his 1869 expedition into the canyons: ‘Though some river rats will disagree with me, I have been able to conclude only that Powell’s party in 1869 survived by the exercise of observation, caution, intelligence, skill, planning – in a word, Science.’

I’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, ‘I don’t know.’ 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 don’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 – 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 ‘survey’ of the Utah territory.

Then Powell the scientist took over – 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 ‘back in the states’; Powell covered those bases, but the heart of his 1879 ‘Report on the Lands of the Arid Region…’ was analysis of the potential of the arid lands for fulfilling Jefferson’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 Act’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) ‘pasturage’ 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 ‘first-come-first-served basis’; 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 – Jefferson’s legendary ‘yeoman’ 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 ‘all radiant with the color of romance,’ with very little attention to ‘the naked facts’ –  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. ‘The naked facts’ 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 – and kept on pushing. He was ‘present at the creation’ of the United States Geological Survey (USGS) in 1879, the same year he presented his ‘Report on the Lands of the Arid Region.’ And two years later he became director of the USGS, where he tried to keep both the Agrarian Romance and ‘the naked facts’ 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 possible successful 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 – 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, Introduction to Indian Languages – which led, two years later to the creation of the U.S. Bureau of Ethnology in the Smithsonian Institute with Powell as director – a position he held until his death in 1902, finally producing the first comprehensive linguistic survey of indigenous tongues, 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 – attention to the naked facts while still trying to carry forward what Bruce Springsteen called ‘the country we carry in our hearts’ – the ever evolving, devolving, careening, diverted, perverted, and currently severely damaged Romance of the American Dream. Next post, we’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 Dellenbaugh’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.

January 30, 2026

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

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

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

“I would just tell you that four days is too long. We got tired of each other,” he said. 

Shawcroft reiterated Tuesday what he and his counterparts from the other Colorado River states have said in recent months: They don’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. 

“I think it’ll be fairly simple, but I think it’ll allow us to operate for the next five years,” Shawcroft said.

The river provides water to 40 million people across the U.S. and Mexico, contributing 27% of Utah’s water supply. It is shrinking because of 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 — Utah, Colorado, New Mexico and Wyoming — are at odds with the Lower Basin states of Nevada, Arizona and California.

The upstream states don’t want to make mandatory cuts in dry years, saying they typically use much less than they’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 “escalating risks” — including declining storage in lakes Powell and Mead — 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 they’ll be managed under the new plan. 

“Lower Basin believes those reservoirs ought to be used at the beck and call of the lower basin to reduce their reductions,” Shawcroft said at the meeting. “Obviously, we think differently.” 

Arizona Gov. Katie Hobbs, for her part, has criticized the upstream states’ “extreme negotiating posture,” saying they refuse to participate in any sharing in managing water shortages.

Demand for water is outpacing the river’s supply, and extended dry periods aren’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 river’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.  

“None of the five can provide what for Utah is really the central consideration for the deal, and that is a waiver of compact litigation,” 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 Reclamation’s plans would have Nevada, Arizona and California face potential water shortages. It could go into effect next year if the seven states don’t reach a deal.  

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

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 have tried unsuccessfully for more than a year 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 isn’t a hard deadline for every detail in the plan, Buschatzke said, but a “deal in principle” probably needs to take shape by then if the states want to control their own destinies.

While the four Upper Basin states in the compact — Colorado, New Mexico, Utah, and Wyoming — rely predominantly on snowpack for water supply, the Lower Basin states — Arizona, California, and Nevada — rely on releases from Lake Powell and Lake Mead..It’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.  

​​”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,” said Andrea Travnicek, the assistant secretary of water and science for the Bureau of Reclamation, in a news release announcing the agency’s latest draft options. “In the face of an ongoing severe drought, inaction is not an option.” 

One of the main disagreements throughout negotiations 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 offers five options — including a required “no action” alternative and four others — that represent a broad range of operating strategies. The draft’s publication initiates a 45-day public comment period ending on March 2, 2026.  In a statement, Scott Cameron, acting lead of the Bureau of Reclamation, said that the federal agency has purposefully not identified a preferred alternative, “given the importance of a consensus-based approach to operations for the stability of the system.”  The expectation is that whatever agreement is reached incorporates elements of all five options offered by the Bureau of Reclamation, Cameron added. 

The five options identified are: 

  • No Action 
  • Basic Coordination
  • Enhanced Coordination 
  • Maximum Operational Flexibility 
  • Supply Driven 


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.

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 don’t go deep enough under some scenarios and flow estimates don’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 “preferred alternative” and plugged into the NEPA process.

“Given the importance of a consensus-based approach to operations for the stability of the system, Reclamation has not yet identified a preferred alternative,” Scott Cameron, the acting Reclamation commissioner, said in a press release. “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.” 

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, 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.

“My initial takeaway is there’s a lot of good stuff in there,” Berggren said of the 1,600-page document, which includes 33 supporting and technical appendices. “Their 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.”

Alternatives

The first alternative is “no action,” meaning river operations would revert to pre-2007 guidance; officials have said this option must be included as a requirement of NEPA, but doesn’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. 

“It was pretty well known that the existing authorities that Reclamation has are probably not enough to protect the system,” Berggren said. “Especially given some of the hydrologies we expect to see, the Basic Coordination does not go far enough.”

The Enhanced Coordination Alternative would impose Lower Basin cuts of between 1.3 million and 3 million acre-feet that would be distributed pro-rata, based on each state’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. 

“There 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,” said Brad Udall, a senior water and climate research scientist at Colorado State University. “Those 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.”

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 Arizona’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.

“You can take the supply-driven one and change the max shortages from 2.1 million acre-feet up to 3 or 4 and it’s going to perform a lot like those other two,” he said. “I 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.”

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.  

“We 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,” the statement reads. “The Colorado River Basin has a history of ignoring likely hydrology, our policymakers should not carry this mistake forward in the next set of guidelines.”

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 can’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.

“Additionally, several alternatives include annual conservation contributions from the Upper Basin between [200,000 acre-feet] and [350,000 acre feet],” the River District’s statement reads. “We do not see how that is a realistic alternative given the natural availability of water in the Upper Basin, especially in dry years.”

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

“Colorado is committed to protecting our state’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,” Colorado’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 feds’ 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 winter’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.

“We’re now at the point where we’ve removed basically all resiliency from the system,” he said. “Between the EIS and this awful winter, some really tough decisions are going to be made. … Once we finally get to a consensus agreement, the river is going to look very, very different than it ever has.”

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

🥵 Aridification Watch 🐫

Just over a month before the deadline for the Colorado River states to agree on a plan for sharing the river’s diminishing waters, the feds released their options, one of which could be implemented if the states don’t reach a deal. The Bureau of Reclamation’s “Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead” offers five alternative scenarios for how to run the river, all of which are aimed at keeping the two reservoirs viable through different methods of divvying up the burden of inevitable shortages in supply.

The document, and the need to deal with present and future shortages, is necessary because human-caused climate change-exacerbated aridification has diminished the Colorado River’s flow, throwing the supply-demand equation out of balance. So it is somewhat surreal to peruse the voluminous report that was published by an administration whose leader has called climate change a “hoax” and a “con job.”

My cursory search of the document turned up only one occurrence of the term “climate change.”1 Yet the authors do acknowledge, if obliquely, that global warming is shrinking the river. “The Basin is experiencing increased aridity due to climate variability,” they write, “and long-term drought and low runoff conditions are expected in the future.” This tidbit also evaded the censors: “Since 2000, the Basin has experienced persistent drought conditions, exacerbated by a warming climate, resulting in increased evapotranspiration, reduced soil moisture, and ultimately reduced runoff.”

All of the alternatives put most of the burden of cutting consumptive use on the Lower Basin states, while directing the Upper Basin to take unspecified conservation measures. I’ll summarize the alternatives below, but first, it seems telling to see which which proposed alternatives the Bureau considered, but ultimately eliminated from detailed analysis.


Colorado River crisis continues — Jonathan P. Thompson


The alternatives do not include:

  • The “boating alternative,” which would prioritize maintaining Lake Powell’s surface level at or above 3,588 feet to serve recreational boating needs. This proposal was put forward in the “Path to 3,588” plan by motorized recreation lobbying group BlueRibbon Coalition. It was dismissed because, basically, it would sacrifice downstream farms and cities for the sake of boating.
  • The ecosystem alternative, which would prioritize the Colorado River’s ecosystem health by focusing management and reducing consumptive human use to protect wildlife, vegetation, habitats, and wetlands.
  • One-dam alternative, a.k.a. Fill Mead First. This proposal would entail either bypassing or decommissioning Glen Canyon Dam with the aim of filling Lake Mead. The Bureau said they rejected the plan because it would be inconsistent with the Law of the River and might be unacceptable to stakeholders (even though some Lower Basin farmers got a little Hayduke-fever a couple of years back, suggesting that ridding Glen Canyon of the dam might be the best way to manage the river).

Okay, so that’s what’s NOT going to happen. So what might happen if the feds feel the need to intervene? Here’s a very short summary of each alternative:

  • No Action: This is always offered in these things, and it just means that they would revert back to the pre-2007 interim guidelines era, when releases from Lake Powell were fixed at an average of 8.23 million acre-feet per year and shortages were determined based on Lake Mead levels and would be distributed based on priority.
  • Basic Coordination Alternative: Lake Powell releases would range from 7 to 9.5 maf annually, based on the reservoir’s surface level, and releases from upper basin reservoirs would be implemented to protect Glen Canyon Dam’s infrastructure. Lower Basin shortages (and cuts) would be based on Lake Mead elevations and would be distributed based on water right priority (meaning Arizona gets cut before California).
  • Enhanced Coordination Alternative: Lake Powell annual releases would range from 4.7 maf to 10.8 maf, based on: a combination of Powell and Mead elevations; the 1-year running average hydrology; and Lower Basin deliveries. The Upper Basin would implement conservation measures to bolster Lake Powell levels if needed, and the Lower Basin shortages would range from 1.3 maf (when Mead and Powell, combined, are 60% full) to 3.0 maf (when Mead and Powell are 30% full or lower) annually. The Lower Basin shortages would be distributed proportionally, meaning that California — which has the largest allocation — would take 49% of the cuts, Arizona 31%, Nevada 3.3%, and Mexico 17%.
  • Maximum Operational Flexibility Alternative: Lake Powell annual releases would range from 5 maf to 11 maf, based on total Upper Basin system storage and recent hydrology. But when Lake Powell’s surface level drops to 3,510 feet, Glen Canyon Dam would be operated as a “run of the river” facility, meaning that it would release only as much as what it running into the reservoir minus evaporation and seepage to keep the elevation from dropping further. Lower Basin shortages would be on a sliding scale, starting when Powell and Mead drop below 80% full, reaching 1 maf when the two reservoirs are 60% full. When the reservoirs drop below 60%, then shortages would be determined by the previous 3-year flows at Lee Ferry, topping out at a maximum shortage of 4 maf. Shortages would be distributed according to priority and proportionally.
  • Supply Driven Alternative: This one is based on the amount of water that is actually in the river (go figure!). Lake Powell releases would range from 4.7 maf annually to 12 maf, or about 65% of the 3-year natural flows at Lees Ferry. Lower Basin shortages would kick in when Lake Mead’s surface elevation drops below 1,145 feet, reaching a maximum of 2.1 maf at 1,000 feet and lower. (As of Jan. 12, Mead’s level was 1,063 feet). Shortages would be distributed according to priority and proportionally.
The estimated “natural flow” 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 what’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.

The Lower Basin states reportedly aren’t too happy about any of the alternatives, because they put most of the onus for cutting consumption on the Lower Basin. Under the Maximum Flexibility option, for example, Lower Basin shortages could go as high as 4 million acre-feet, or about half of those states’ total annual consumptive use. And under another, California alone could have to cut up to 1.5 million acre-feet of water use, which could trigger litigation, since California users have some of the most senior rights on the river. Some of the alternatives would potentially nullify the Colorado Compact’s clause ordering the Upper Basin to “not cause the flow of the river at Lee Ferry to be depleted below an aggregate of 75 maf for any period of ten consecutive years.”

The Bureau does not pick a “preferred” alternative, like federal agencies typically do with environmental impact statements, leaving readers guessing about which option or combination of options might be chosen should the need arise. But it also gives more room for the states to reach some sort of agreement to pick an option from the provided list.

* It is found in the Hydrologic Resources section: “While the flows in the Colorado River would not affect groundwater in the region, changes to the groundwater systems in the Grand Canyon due to climate change may be an additional environmental factor that affects flows in the Colorado River.”


The snowpack remains dismal in most of the West, and it’s not just because of lack of precipitation. In fact, it’s probably more due to the crazy-warm temperatures. The average temperatures across the Interior were way above normal in November and December, as the map below shows. And January’s similarly unseasonably balmy so far. Yikes.

Precipitation levels were mixed across the West during late autumn and early winter, but temperatures were warmer than normal across the entire region, diminishing snowpack and leading to rather unwintery conditions. Source: NOAA.

🌵 Public Lands 🌲

Last week the new public lands media outlet, RE:PUBLIC, warned readers of “major shrinkage” this year. They meant, of course, that the Trump administration will probably get around to eliminating or eviscerating at least one national monument in the next twelve months. It’s probably a pretty safe bet, given that in Trump’s first term he shrank Bears Ears and Grand Staircase-Escalante national monuments, and Project 2025, which the administration has hewn closely to, calls for even more reductions.

Indeed, I’m surprised they haven’t already moved to eliminate some of these protected areas, especially the more recently designated ones like Bears Ears, Baaj Nwaavjo I’tah Kukveni-Ancestral Footprints of the Grand Canyon National Monument, or Chuckwalla National Monument in California. An optimist might hope that the Trump administration has realized how deeply unpopular this would be, or has come to terms with the fact that the Antiquities Act only allows presidents to establish national monuments, not eliminate them. But I think it’s more likely they were simply too busy dismantling other environmental safeguards — and, for that matter, democracy — to get around to diminishing national monuments.

I was a little surprised by RE:PUBLIC’s list of vulnerable national monuments, however. It included Bears Ears et al, which makes sense, but then also speculates about other “likely targets, due to their proximity to energy and mining interests,” including: Aztec Ruins, Dinosaur, Hovenweep, and Natural Bridges national monuments.

I hate trying to predict what the Trump administration will do in the future, but I’m going to go out on a limb here and say that these particular national monuments are not in the administration’s crosshairs. While these protected areas are close to energy-producing areas, and probably have some oil and gas, uranium, lithium, and/or potash producing potential, they simply offer too little to the extractive industries to make it worth the political blowback from eviscerating them.

For those who may be unfamiliar with these places, I’ll take each one individually:

  • Aztec Ruins: First off, this tiny national monument adjacent to the residential neighborhoods of Aztec, New Mexico, is an amazing place and well worth the visit. The Puebloan structures here are built in the style of Chacoan great houses, and the community — which was established at the end of Chaco’s heyday — may have been become succeeded Chaco as a regional cultural and political center. It is in the San Juan Basin coalbed methane fields and is surrounded by gas wells. In fact, there are a few existing, active wells within the monument boundaries. But no one is champing at the bit to drill any new wells in this region, and they certainly don’t need to do so in this tiny monument.
  • Dinosaur National Monument, in northwestern Colorado, is probably somewhat vulnerable, given its size and proximity to oil and gas fields. But again, there’s not a whole lot of new drilling going on in the area. It was established in 1915 to protect dinosaur quarries — clearly in tune with the Antiquities Act — so shrinking it would be met with serious bipartisan political pushback.
  • When Warren G. Harding designated Hovenweep National Monument in 1923 to protect six clusters of Puebloan structures in southeastern Utah from development and pothunters, he strictly followed the Antiquities Act’s mandate to confine its boundaries to “the smallest area compatible with proper care and management of the objects to be protected.” As such, the boundaries of each “unit” is basically drawn right around the pueblo and a small area of surroundings, leaving little room for shrinkage. Though it lies on the edge of the historically productive Aneth Oil Field, oil and gas drillers have no need to get inside the boundaries to get at the hydrocarbons. Besides, Trump and Harding have a lot in common, so Trump’s not likely to want to erase his predecessor’s legacy.
  • Natural Bridges: It’s odd to me that this one, which is currently surrounded by Bears Ears National Monument, is included on this list. Yes, there are historic uranium mines nearby, and yes, White Canyon, where the monument’s namesake formations are located, was once considered for tar sands and oil shale development. But the small monument itself — which was designated by Teddy Roosevelt in 1908 — is not getting in the way of any of this sort of development. It’s much more likely that Trump would remove the White Canyon area from Bears Ears National Monument, as he did during his first term, potentially opening the area around Natural Bridges back up to new uranium mining claims, while leaving the national monument’s current boundaries intact.

So, in summary: Don’t fret too much about these national monuments getting eliminated or shrunk anytime soon. And for now, maybe we shouldn’t worry about any national monument shrinkage. It is possible that Trump won’t go there this term. Trump shrunk Bears Ears and Grand Staircase-Escalante during his first term in part out of spite toward Obama and Clinton, but also to get then-Sen. Orrin Hatch’s legislative support. That the shrinkage also re-opened some public lands to new mining claims and drilling was a secondary motivation.

This time around, Trump has come up with far more generous gifts for the mining and drilling companies, and much more sinister ways to attack his political adversaries. Besides, he’s got his eyes on much bigger prizes — like Greenland.

January 15, 2026

Absent a crucial but elusive consensus among the seven Colorado River 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 — Colorado, Wyoming, Utah, New Mexico, California, Arizona and Nevada — already blew past a Nov. 11 deadline 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…

“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,” Andrea Travnicek, the assistant secretary for water and science at the Department of the Interior, said in a news release announcing the document.  “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.”

A 45-day public comment period opens Friday on the proposed plans 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 — on the Arizona-Nevada border — and Lake Powell are only 33% and 26% full, respectively. Projections from the Bureau of Reclamation show that, in a worst-case scenario, Powell’s waters could fall below the level required to run the dam’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.

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. 

 “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,” 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.” 

 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 Action 
  • Basic Coordination 
  • Enhanced Coordination 
  • Maximum Operational Flexibility 
  • Supply Driven 

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 Reclamation’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 – the start of the 2027 water year.

Key Takeaways

  • The consensus-based effort to develop new rules to manage the Colorado River system hasn’t worked – it’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. Valentine’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 can’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 state’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. It’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 – or a political imperative – 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 state’s interests.

But federal leadership alone is not enough – 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 “to develop future operating guidelines and strategies to protect the stability and sustainability of the Colorado River.” 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 (“recover”) the roughly 5.6 million acre-feet (MAF) of water stored in Lake Powell below the minimum power pool elevation 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 “compact call” 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% – 60%: cuts to Lower Basin water uses increasing from 0 to 1.5 MAF<60% – 38%: static cut to Lower Basin water uses of 1.5 MAF<38% – 23%: increasing cuts to Lower Basin water uses of up to 3.0 MAF total
    • below 23% of total system contents – 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% – 23%: Assuming the first 0.25 MAF “reduction” would be contributed by the elimination of Powell’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 – 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 of Extraordinary Conservation ICS and DCP ICS 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 “reasonable and beneficial use” 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 plan’s duration will need to be determined. But as temperatures again climb into the high 40s in the Rockies near the Colorado River’s headwaters (in mid-December!), drying soils and reducing next year’s runoff, and the National Weather Service issues red flag fire warnings for Colorado’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 – 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 “dead storage” – 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 year’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 that’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 doesn’t ensure a better outcome and certainly won’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 – the reservoir’s namesake – demonstrated bold leadership, going where no (white) man had gone before. With leadership and a clear goal, he charted a route through the Colorado River’s iconic canyons. Now is the time for more bold leadership, a clear goal, and a plan to get there.

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 states’ 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 ’25-’26 water year) and long-range planning, such as the development of the next “Minute” agreement between the United States and Mexico.

The closing act of CRWUA 2025 was an orderly (and familiar) report from each of the basin states’ 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 – vital to informed decision-making – will be greatly reduced.

Still, as Rhett Larson of Arizona State University said on the first day of the conference, “Desert rivers bring people together.” 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 River’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: “If 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.” 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 states’ 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 — 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 government’s Valentine’s Day deadline for a consensus-based deal.

States far from deal — with less than 60 days left

Unlike last year’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. That’s because the stakes are high for states to meet Burgum’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 don’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

Nevada’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 “going nowhere,” 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 agency’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 — and that hydropower generation can continue.

December 16, 2025

A new report from Colorado Law’s Colorado River Research Group warns the Colorado River Basin is “out of time,” describing conditions so severe they threaten the region’s water supply, economy and governance. Called “Colorado River Insights 2025: Dancing with Deadpool,” the report details a dire assessment of the basin’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. 

“This report underscores that the basin is out of time, the crisis is no longer theoretical,” 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.

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

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 — far short of what’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. 
  • Safety nets collapsing: Groundwater reserves are rapidly depleting, while federal capacity — funding, staffing and science programs — 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. It’s a risky move that no one in principle seems to want. Yet brinkmanship and entrenched positions have stymied compromise.

The basin’s Indian tribes, which collectively have rights to more than a quarter of its recent average annual flow, are adamant that their interests – and more broadly, the river itself – be protected. “Any 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,” 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.

Click the link to read the article on the National Parks Traveler website. Here’s an excerpt:

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 was 1061.76 feet, according to the U.S. Bureau of Reclamation. At Glen Canyon National Recreation Area, which straddles the Utah-Arizona border, the Park Service has spent more than $100 million in recent years to extend boat ramps and relocate a takeout for river runners coming down the Colorado River through 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 – and pressure is mounting as the federal government pushes for a compromise and a troubling forecast for the river’s two biggest reservoirs looms.

Top water officials for the seven Colorado River Basin states — Arizona, California, Nevada, Colorado, New Mexico, Utah, and Wyoming — 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 —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.

Nevada’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.

“If you distill down what my six partners just said, I believe there’s three common things: Here’s all the great things my state has done. Here’s how hard/impossible it is to do any more. And here are all the reasons why other people should have to do more,” Entsminger said.

“As long as we keep polishing those arguments and repeating them to each other, we are going nowhere,” he continued.

The seven states that share the river’s flows have been deadlocked for nearly two years over how to govern the waterway through the coming decades — 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 River’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 Department’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 River’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, it’s possible Lake Powell’s levels could drop low enough to cease hydropower production by next October — a scenario that would also limit the department’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 Reclamation’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 states’ river negotiators.

“The expiration of the current agreements is not a distant horizon. It’s less than a year away. The time to act is now,” said Cameron.

Within the next few weeks, the Bureau of Reclamation will release a range of proposals to replace the river’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. California’s biggest water districts said they were willing to “set aside many of their legal positions” in order to reach a seven-state agreement.

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

“I went into this process…advocating strenuously for a 20- to 30-year deal,” said Entsminger. “I no longer believe that’s possible with the time we have left and with the hydrology that we’re facing.”

Entsminger said the “best possible outcome at this juncture” 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 can’t take on more cuts.

“Our savings accounts are totally depleted,” said Utah’s’s river negotiator, Gene Shawcroft. “Reserviours were full when we started this process. They’re empty now.”

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 – Nevada, Arizona, and California – 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 Arizona’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 – Colorado, Wyoming, New Mexico, and Utah – to split any additional water cuts with the Lower Basin states 50-50.

“We need conservation in the Upper Basin that is verifiable and mandatory,” Buschatzke said, during the panel.

“I have to go to my legislature and get that approval,” he continued. “And 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.”

New Mexico’s river negotiator, Estevan López, responded, “I think we’ve been pretty clear. We are unwilling to require additional mandatory reductions on our water users.”

In Brief

The rains of mid-October caused significant flooding in the San Juan River basin and increased reservoir storage throughout that basin and in Lake Powell.7 However, basinwide reservoir storage remains low, and the October rainfall offerings were insufficient to alleviate the peril of declining overall water supply.

While the attention of the Basin’s water management community remains focused on the thus far unsuccessful effort to forge a seven-state agreement on future long-term operating rules, the Basin continues to face the risk of short-term crisis. If winter 2025-2026 is relatively dry and inflow to Lake Powell and other Upper Basin reservoirs is similar to that of 2024-2025, low reservoir levels in summer 2026 will challenge water supply management, hydropower production, and environmental river management. Under such a scenario, it is likely that less than 4 million acre feet in Lake Powell and Lake Mead would be realistically available for use during the nine months between late summer 2026 and the onset of snowmelt runoff in 2027. If winter 2026-2027 is also dry, water supply would be further constrained. The present reservoir operating rules that remain in place through 2026 are insufficient to avert this potential water supply crisis. Action to further reduce consumptive water use across the basin is needed now.

How did we get here?

The Basin’s reservoirs were nearly full in late summer 1999,8 acting as a buffer against dry years and serving their fundamental purpose. At that time, the 46 Colorado River Basin reservoirs tracked by the Bureau of Reclamation in its Hydro database held 59.5 million acre feet (maf) in active storage,9 more than four times the Basin’s average consumptive uses and losses in the 1990s (Fig. 1).10 Beginning in 2000, five years of below average runoff11 resulted in a 46% reduction in storage in the Basin’s reservoirs.12 During that time, the reduction in storage in Lake Powell and Lake Mead accounted for 90% of the Basin’s total loss in storage, because most of the Basin’s water was stored in those two reservoirs.

During the next fourteen and a half years, the amount of storage in the Basin’s reservoirs changed little, despite four years of large runoff (2005, 2011, 2017, and 2019). The increase in storage during the few wet years was nearly completely consumed during the more frequent dry years, and active storage in Powell and Mead was only 5% greater in late July 2019 than it had been at the beginning of 2005.13 When dry years of low runoff returned between 2020 and 2022,14 the Basin’s water users had little of the buffer that they had at the beginning of the 21st century. Combined active storage of Powell and Mead was halved again between mid-July 2019 and mid-March 2023,15 reducing the combined contents of these two reservoirs to only 27% of what it had been in late summer 1999.16 If next winter’s runoff is as low as it was in 2025 17 and consumptive use is not significantly reduced, Powell and Mead will drop below the previous unprecedented low stand of mid-March 2023.

How much of active storage is realistically available?

One of the challenges of the current water supply crisis is uncertainty over how much water is actually available in the reservoirs for use. Although Reclamation regularly reports the amount of water in active storage, our analysis identifies realistically accessible storage as the more appropriate metric of the amount of water that is available for use without challenging the integrity of the dam structures, efficient production of hydroelectricity, or implementation of environmental river management protocols, especially in Grand Canyon.

The back of Glen Canyon Dam circa 1964, not long after the reservoir had begun filling up. 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.

Reservoir water that can be physically released from a dam is termed active storage. In virtually all reservoirs, there is a small amount of water below the elevation of the lowest outlets–the infamously named dead pool. Active storage is everything above dead pool–water that can be physically released through the reservoir’s lowest outlets.

We know, however, that not all the water above dead pool is readily usable. Engineering assessments have indicated that infrastructure constraints at Hoover and Glen Canyon Dams require that higher reservoir elevations be maintained, thereby constraining utilization of the lowest part of the active storage. We defined realistically accessible storage as the volume of water whose release does not impact previously identified engineering or hydropower-production constraints.

At Glen Canyon Dam, for example, the lowest release tubes, called the “river outlets,” are at elevation 3370 ft. Reservoir water below that elevation cannot be released and constitutes the dead pool. Above the river outlets, at elevation 3490 ft, are the intakes for the power generating turbines, known as the penstocks. The penstocks are the conduits that withdraw water from the reservoir into the powerplant to generate electricity, and thereafter discharge the water to the Colorado River downstream from the dam. When the reservoir falls below the elevation of the penstocks, the river outlets are the only means of discharging water through the dam (Fig. 2). The river outlets are not routinely used to release water; virtually all normal releases go through the penstocks.

Experience has shown that the river outlets were not designed for continuous release at the discharge rates required to meet downstream obligations. If the river outlets were to be used continuously, there is significant concern that structural damage to those outlets could occur.18

Accordingly, Reclamation has determined that it will take steps to avoid Lake Powell elevation declining below 3500 ft, considered a safe elevation for continuous withdrawal of water through the penstocks without risk of harm caused by cavitation to the turbines that produce electricity.19 Similarly at Lake Mead, Reclamation has indicated its intent to protect the reservoir from going below elevation 1000 ft.20

Figure 2. Diagram showing schematic of Glen Canyon Dam elevations at which Lake Powell’s waters can be released downstream, and the volumes of water defined by these elevations. Active storage between 3370 and 3500 ft is not realistically accessible for continuous downstream release without risk to engineering infrastructure at the dam and powerplant. Hydroelectricity cannot be produced below 3490 ft, and 3500 ft has been established as a minimum safe level for intake through the penstocks.

The total volume of active storage in Lake Powell above dead pool but below elevation 3500 ft is 4.2 maf. Release of this stored water is constrained, because it cannot be safely withdrawn through the penstocks, and continuous use of the river outlets is considered unwise. At Hoover Dam, there is 4.5 maf of active storage below elevation 1000 ft, also not realistically accessible. In these two largest reservoirs of the Colorado River Basin, there is a total of 8.7 maf of active storage below the elevations required for safe and efficient operation of the infrastructure (Fig. 3). Thus, of the 14.9 maf of active storage at Lake Powell and Lake Mead on November 15, 2025, only 42% of that active storage, 6.2 maf, was realistically accessible.

Implementation of environmental river management protocols at Glen Canyon Dam are constrained when the elevation of Lake Powell is low. Since 1996, controlled floods, administratively termed High Flow Experiments (HFEs), have been conducted at Glen Canyon Dam to rebuild eddy sandbars along the river’s margin and conserve sediment. HFEs are now an essential component of the Long Term Experimental and Management Plan for Glen Canyon Dam.21 Reclamation did not, however, release an HFE in 2021 or 2022 when sediment conditions were sufficient to trigger implementation of the HFE Protocol because Lake Powell was low. In early October of those years, when decisions about implementing HFEs were made, active storage in Lake Powell was 7.3 maf (elevation 3545.3 ft) and 5.8 maf (elevation 3529.4) in 2021 and 2022, respectively. Reclamation cited low storage as the reason not to release those controlled floods.22 Although administrative decisions change with time, it is doubtful that any HFEs would be released if Lake Powell fell below elevation 3500 ft.

Low reservoir levels also impact Reclamation’s ability to control the invasion into Grand Canyon of smallmouth bass, and other warm water reservoir fish species, that dominate the recreational fish community of Lake Powell. These nonnatives are significant predators and competitors of endangered or threatened native fish species and live near the surface of Lake Powell. At moderate and low reservoir elevations, water withdrawn through the penstocks (termed fish entrainment) includes some fish that survive passage through the powerplant turbines and are delivered into the Colorado River downstream from the dam. These fish have the potential to successfully spawn downstream from the dam if river temperatures are relatively warm, such as occurs when Lake Powell is low and water is only released through the penstocks.

Reclamation has implemented a protocol to eliminate the potential of smallmouth bass population establishment in Grand Canyon by releasing some cooler water through the river outlets when the water released through the penstocks is warm. The objective of these Cool Mix releases is to disrupt smallmouth bass spawning downstream from the dam. Water released through the river outlets bypasses the powerplant and does not produce electricity, and Western Area Power Administration (WAPA) must purchase electricity on the open market to replace electricity that the agency contractually committed to provide. WAPA estimated that the cost of replacing contracted electricity was $18.9 million23 and $6.5 million24 during the Cool Mix releases of 2024 and 2025, respectively. The risk of fish entrainment from Lake Powell increases significantly as Lake Powell’s elevation drops, and the need to implement the Cool Mix protocol therefore increases. The risk is minimized if Lake Powell is higher than 3590 ft (10.8 maf active storage) and significantly increases when Lake

Powell is below 3530 ft (5.8 maf active storage).25 When water is no longer withdrawn through the penstocks, the risk of entrainment decreases, because all water passes through the lower elevation river outlets.

What would happen if the coming winter and spring snowmelt is similar to 2024-2025?

In an analysis released in September 2025, we reviewed what might happen in the coming year if runoff is the same as it was last year and Basin consumptive uses and losses are the average of the past four years. We used a simple mass balance approach and estimated the available water supply and consumptive uses and losses, and calculated the difference between the two. The available water supply is the sum of the natural flow of the Colorado River at Lees Ferry plus inflows that occur in the Lower Basin, primarily in Grand Canyon. Consumptive uses and losses are those associated with diversions that support irrigated agriculture, municipal and industrial use, water exported from the Basin by trans-basin diversions, and reservoir evaporation. The difference between supply and use is the net effect on reservoir storage. We then estimated the effect of the Basinwide imbalance between supply and use on the combined realistically accessible storage in Powell and Mead, i.e., above elevations 3500 and 1000 ft in Lake Powell and Lake Mead, respectively.

In the scenario that we considered, we assumed that natural flow at Lees Ferry in the coming year will be 8.5 maf, the same as in Water Year 2025,26 and inflow in the Grand Canyon is 0.8 maf. Thus, we assumed a total supply in the coming water year of 9.3 maf. We analyzed a scenario wherein consumptive uses and losses in the United States portion of the Colorado River would be the average of the most recent four years (2021-2024), namely 11.5 maf,27 and we assumed that 1.4 maf would be delivered to Mexico.

The gap between supply and use under this scenario is 3.6 maf, which would have to be met by additional withdrawals from reservoir storage. Assuming that 75% of this deficit would be withdrawn from Lake Powell and Lake Mead (2.7 maf), then the realistically accessible storage in these two reservoirs would be reduced to 3.5 maf, slightly less than the 21st century low that occurred in mid-March 2023 (Fig. 3). Our analysis of this one realistically low inflow scenario–the coming year’s supply is just like last year’s and consumptive uses and losses are the average of the past four years–is consistent with, but less dire than, Reclamation’s most recent 24-Month Study minimum probable forecast28 for the coming year. That study projects that total storage in Lake Powell and Lake Mead will be drawn down by 3.8 maf during the next year, 2.9 maf from Lake Powell alone. Under Reclamation’s minimum probable projection, the elevation of Lake Powell would drop below 3500 ft in August 2026. All of the remaining realistically accessible storage, 2.5 maf in the scenario modeled by Reclamation, would be in Lake Mead. Under the assumption that the current operating rules remain in effect in 2027, Reclamation’s projection is that the elevation of Lake Powell would stay below elevation 3500 ft through at least July 2027.

Further complicating the situation is that the status and ownership of water in Lake Mead at very low storage levels is unclear. Lake Mead holds (a) water available for allocation in the Lower Division under the prior appropriation system, (b) at least some amount of the water due to Mexico under treaty obligations, and (c) assigned water. Assigned water, commonly known as Intentionally Created Surplus or ICS, is water that can be delivered independent of the Lower Basin’s prior appropriation water allocation system and that is held in Lake Mead by the Secretary of the Interior for the benefit of a specific entity. Assigned water also includes delayed water deliveries held for the benefit of the Republic of Mexico that can be delivered subsequently in amounts in excess of the U.S. treaty obligation to Mexico of 1.5 maf/year. Owners of assigned water have the right to withdraw that water when Lake Mead water levels are above 1025 ft, but entitlement holders in the priority system also have a right to water deliveries, as does Mexico via treaty.

Sketches by Floyd Dominy show the way he’d end the Glen Canyon Dam. From the article “Floyd Dominy built the Glen Canyon Dam, then he sketched its end on a napkin” on the Salt Lake Tribune website.

So long as there is water in Lake Mead adequate to fulfill all required and requested deliveries, no conflict arises. However, as the amount of water in Lake Mead decreases, the potential for a clash increases. International treaty obligations take precedence over deliveries pursuant to the priority system within the U.S., but it is unclear how competing priorities and entitlements will be resolved within the U.S. Holders of higher-priority entitlements would likely contest the Secretary’s authority to reduce their deliveries while withholding assigned water from the priority system. As of the end of 2024, there was approximately 3.5 maf of assigned water in Lake Mead, almost the same as the amount of realistically accessible water in storage above elevation 1000 ft. If Lake Powell ever became a “run of the river” facility, the potential for conflict over access to water in Lake Mead would also increase.

Implications

We are not weather forecasters and have no crystal ball that reveals the coming winter snowpack. We are not predicting that our assumptions about the gap between supply and use/losses and the resulting drawdown of Lake Powell and Lake Mead will inevitably occur. Our scenario is merely one of many possibilities, but our assumptions are sufficiently realistic to serve as a warning of how close the Basin is to a true water crisis. Our results should serve as a call to action. We need to adopt additional and immediate measures across the Basin to reduce water consumption even further during the next year, well before any new guidelines are in place.

Taking steps now to decrease consumptive uses across the Basin will reduce the need to implement draconian measures next summer or in the following years. Every acre foot saved now is an acre foot available for our future selves, slowing the rate of reservoir decline and creating more room for creative Colorado River management solutions. If, on the other hand, we delay reducing water usage and addressing reservoir drawdown, we may find ourselves in more significant distress at the beginning of the Post-2026 guidelines. As we wrote in October, continued reduction in Lake Powell releases also brings the Basin perilously close to the Colorado River Compact “tripwire,” the point at which the ten-year rolling total of water delivered from the Upper Basin to the Lower Basin might trigger litigation asking the U.S. Supreme Court to interpret long avoided ambiguities in rules written a century ago by the drafters of the Colorado River Compact.

We do not presume to make specific recommendations about the steps that should be taken immediately to reduce consumptive use in the Basin. There are many smart and experienced individuals in the Colorado River community whose sole focus is on the mechanics of operating the Colorado River water system and the impacts of operations on their particular constituencies.

We can, however, highlight the available mechanisms for reduction of consumptive use that should be explored for their immediate utility in diminishing the looming jeopardy to the overall system. Such mechanisms include:

    • Releases from federal reservoirs upstream of Lake Powell to stabilize storage in Lake Powell.
      • Such releases would be made pursuant to the Drought Response Operations Agreement or similar successor agreement or pursuant to the Secretary of the Interior’s inherent authority to operate federal water projects. Obviously, such releases do nothing to solve the imbalance between supply and demand and will create additional depletions in the system when these reservoirs are refilled. Such releases can, however, provide a temporary bulwark against exceptionally low levels in Lake Powell.
    • Additional reductions in deliveries from Lake Mead under the Secretary’s Section 5 delivery contracts in the Lower Basin, as authorized by Section II.B.3 of the decree in Arizona v. California, 376 U.S. 340 (1964).
      • By reducing deliveries from Lake Mead, releases from Lake Powell could also be reduced without the risk of causing exceptionally low storage in Lake Mead.
    • Extension of system conservation programs in the Lower Basin, and facilitation of an Upper Basin water conservation program, both funded through compensation from federal or state governments or other water users in the Basin, and requiring specific quantities of saved water.
      • Relying on compensated annual forbearance alone is unsustainable, however, because it is not feasible to pay water users in the long term to forgo the use of water that nature no longer supplies. Permanent reductions in consumptive use are both necessary and also the most productive use of limited funding. In addition, to be effective, changes to state law in some Upper Basin states may be necessary, including recognition of water conservation as a beneficial use for the purpose of avoiding litigation concerning the Colorado River Compact. Finally, authorization for shepherding of saved water to the intended place of storage is essential, including across state borders.
    • Reductions in deliveries to Mexico through negotiation of a new minute.
    • Reductions in consumptive use by federal water projects in the Upper Basin, if allowable pursuant to the Secretary’s authority.
      • It should be noted, however, that in order to benefit the Colorado River system, any such reductions must be recognized at the point of diversion and shepherded to the intended place of storage.

    It is obvious that any long-term agreement for future Colorado River operations among the Basin States should be evaluated based on its immediate ability to reverse the storage declines experienced in recent years and anticipated in the future under similar hydrology. An agreement that does not reliably balance supply with uses and losses is not sustainable. Similarly, any operational alternative proffered by the Department of the Interior must achieve the same objectives. When our reservoir storage is as low as it is now, we have very little buffer to rely on–we simply cannot use more water than nature provides.

    The focus within the Basin and among its principal water users and state negotiators has been on the formulation of the Post-2026 guidelines for operation of the river. But action is necessary now to avoid creating conditions that will doom the next set of operating principles by initiating their implementation when the Basin is in full crisis mode. No governmental administration, state or federal, wants to see the Colorado River system fail on its watch. Negotiators have worked tirelessly to reach agreement, yet have come up short. The hour is late. The Secretary must take decisive action.

    December 17, 2025

    Federal officials have released a “sobering” 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 river’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 River’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).

    “We all know Mother Nature is a trickster and can often confound our expectations. We certainly hope she intends to do that this year,” said Wayne Pullan, the Bureau of Reclamation’s regional director for the Upper Colorado River Basin, on Tuesday. “But December’s outlook is troubling.”

    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 lake’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 River states have been given less than two months to agree on how to share water cuts from the shrinking river.
    • Homeland Security waives environmental laws to speed the construction of a border wall in parts of New Mexico.
    • A federal judge proclaims federal authority over the contentious Line 5 oil pipeline that crosses the Great Lakes.
    • U.S., Mexican governments sign Tijuana River sewage cleanup agreement.
    • The House passes a bill to change environmental reviews for infrastructure permitting.
    • USGS study finds lower water levels in Colorado’s Blue Mesa reservoir the cause of increased 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.

    “Let 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.” – 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 Interior’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 basin’s tribes. And it allows for reservoir operating decisions in 2027 to be set this fall.

    “Time is of the essence, and it is time to be able to adjust those stakes, to arrange so compromises can be made,” Travnicek said.

    On the Radar

    Colorado River Draft EIS Coming Soon
    In the coming weeks – in early January if not by the end of the year – 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 “broad range” 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.

    “We’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,” Jerla said.

    December 18, 2025

    The seven states that rely on the Colorado River 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 river’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, 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. The U.S. Bureau of Reclamation has set a new deadline of Feb. 14.  Nevada’s lead negotiator said it is unlikely the states will reach agreement that quickly. 

    “As we sit here mid-December with a looming February deadline, I don’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,” 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 — preferring the seven basin states reach consensus themselves. If they don’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.

    “It’s a rabbit hole you can dive down in, and it is incredibly complex,” 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, don’t think they should have to make additional cuts because they already don’t use their full share of the water and are legally obligated to send a certain amount of water downstream.

    “Our water users feel that pain,” said Estevan López, New Mexico’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 nation’s two largest reservoirs: Lake Powell and Lake Mead. The report provided a sobering backdrop to the Colorado River Water Users Association conference at Caesar’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 Powell’s projected 2026 inflow of 1 million acre-feet since the November forecast. Under the “minimum” 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 “most probable” forecast, the reservoir’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 bureau’s Upper Basin, called the December projections troubling.

    “That outlook is sobering for all of us,” Pullan said at Tuesday’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 — with long periods of being deadlocked in disagreement — 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.

    “We have learned that if we failed at all in these last 25 years, it might have been that our vision wasn’t sufficiently pessimistic,” Pullan said.

    States’ 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.

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

    Not a routine water source

    This isn’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 — Flaming Gorge, Navajo and Blue Mesa — 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 Colorado’s largest reservoir, which is on the Gunnison River.

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

    “I appreciate as we’re in critical and dire situations how we use our resources to protect our infrastructure, but we have to shift,” Mitchell said. “Our biggest resource is post-2026 and figuring out how do we do this in a way that doesn’t create those to be routine water sources.”

    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. 

    “(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,” 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 river—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. 

    “It’s now 2025, we’re here in a different hotel a couple years later and the same problems are on the table. In the last two years, we’ve been spinning our wheels,” said JB Hamby, California’s lead negotiator, at the annual Colorado River Water Users Association conference.“Time has been wasted, and like water, that’s a very precious resource.”

    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 nation’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 latter’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. 

    The federal government’s data indicate that Lake Powell could drop to that level, known as “deadpool,” by the summer of 2027 if significant cuts aren’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 a proposal 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 river’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 another 2 to 4 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 they’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.

    “As long as we keep polishing those arguments and repeating them to each other, we are going nowhere,” said John Entsminger, Southern Nevada Water Authority’s general manager, and that state’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 government’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 Women’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. 

    ”All the people on the ground really need to step up and provide a solution,” 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.

    “We might invest in sources that we don’t need, but also we may have to restrict water deliveries from time to time, as we’ve done in the past,” said Hasencamp. “For us, that’s a fail.”

    But Tom Buschatzke, the director of the Arizona Department of Water Resources and the state’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 Basin’s claim that they can’t take more cuts is “absurd” and is based on them not getting their “paper” water—a term used to refer to water that exists legally but has never been put to use or proven to currently be available. 

    “They need mandatory conservation that results in more water being in Lake Powell that can be moved to Lake Mead,” 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. “We cannot subsidize overuse,” said Becky Mitchell, Colorado’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 river’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 region’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 it’s unfair for those four states to sacrifice their future.

    Earlier this week, leaders in both basins saw a preview of the federal government’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, California’s negotiator, emphasized that if the basin states eventually reach an agreement, it will determine how the federal government manages the river.

    “Ultimately, none of it should matter if we get to a seven-state consensus,” said Hamby, who is also a board member of Southern California’s Imperial Irrigation District, the river’s single-largest water user. “But 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.”

    Brandon Gebhart, Wyoming’s state engineer and Colorado River negotiator, called the analysis “broad enough to accommodate any seven-state consensus agreement” 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 weren’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.

    “I came with very low expectations, and they were met,” she said.

    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 – which manages water in the West under the Interior Department – is on track to release a draft environmental review by early January with a range of options to replace the river’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 Association’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.

    “The Department of the Interior recognizes a shrinking timeline is in front of us in order to operate under a new potential agreement,” 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. 

    “We will not be identifying a preferred alternative, but we anticipate the identification of that between the draft and the final,” said Bureau of Reclamation’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 river’s shrinking water supply. 

    “We 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,” Jerla continued.

    Lower Basin states — California, Arizona, and Nevada — and Upper Basin states — Colorado, Wyoming, Utah and New Mexico — have been at an impasse for months over how to manage the Colorado River’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 river’s operating guidelines after days of intense closed-door negotiations.

    States’ 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 Reclamation’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 states’ river negotiators.

    “There are a number of issues from decades past that some people are having some difficulty getting past,” Cameron said, adding that states must “be willing to set aside previous perceived inequities and unfairness.”

    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 “cautiously optimistic” states will reach a consensus deal by the February deadline.

    “It’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,” Cameron said.

    On Tuesday, California’s biggest water districts said they were willing to “set aside many of their legal positions” in order to reach a seven-state agreement.

    The Bureau of Reclamation provided a broad overview of the components that will be included in draft’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, Reclamation’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.

    “We want to preserve ourselves the flexibility to come back to the table, to do reviews, to make consensus adjustments if needed,” 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.

    “We’re monitoring the forecast, and we’re seeing not a great start to water year 2026. It’s still early in the year, but the way things are setting up it isn’t looking good,” 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.

    December 17, 2025

    LAS VEGAS — 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. It’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 river’s future.

    The basin’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, Colorado’s governor-appointed negotiator on Colorado River issues.

    “We’re in a precarious time because none of that is enough,” Mitchell told hundreds of audience members during an Upper Colorado River Commission meeting Tuesday. “It has not been enough.”

    Natural flows — which is a calculation of how much water would pass Lees Ferry without upstream human intervention — 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 river’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 states’ proposal to manage the basin’s reservoirs. If not, the federal officials will decide what to do.

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

    “It’s not political positions. It’s not legal interpretations,” Brandon Gebhart, Wyoming’s top negotiator, said. “It’s the hydrology of the entire basin.”

    Others, including some of the 30 tribes in the basin, saw it differently. Some tribal representatives called for more transparency. Others said they couldn’t support a plan that is geared toward sending water to downstream states.

    “Despite those that think hydrology is the problem, it’s not, and it can’t always be the scapegoat,” said Kirin Vicenti, water commissioner for the Jicarilla Apache Nation, located within New Mexico just south of the Colorado state line. “Our planning and policies must allow flexibility, and innovative and dynamic solutions.”

    Relationships between upstream states and Lower Basin states — Arizona, California and Nevada — 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.

    “We know one thing for sure, which is that we have a smaller river and that requires less use,” JB Hamby, chairman of the Colorado River board and California’s top negotiator, told the gathering.

    He lauded California’s “massive” and expensive efforts to address the river’s shrinking supply while still growing the state’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.

    “We 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,” Hamby said. “We must all live with the resources we have, not the ones that we wish for.”

    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 group’s discussion.

    “We appear to be talking past each other,” 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 basin’s challenges don’t end next fall — 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 what’s in the media, he said.

    “Squeezing it (water) out of the Upper Basin isn’t going to make enough water for the Lower Basin demands,” Curtis said. “And that may be a biased view, obviously, so I’m trying to get a little bit beyond my own biases.”

    Where Colorado and other Upper-Basin states need to retreat from trying to develop full compact allocation. But Lower Basin states need to acknowledge Mother Nature.

    This was published on Dec. 13, 2025, in the Calexico Chronicle, a publication in California’s Imperial Valley. It is reposted here with permission, and we asked for that permission because we thought it was an interesting explanation from a close observer who was reared in an area that uses by far the most amount of water in the Colorado River Basin.

    This week is the annual gathering of “water buffaloes” in Las Vegas. It’s the Colorado River Water Users Association convention. About 1,700 people will attend, but probably around 100 of them are the key people — the government regulators, tribal leaders, and the directors and managers of the contracting agencies that receive Colorado River water.

    Anyone who is paying attention knows that we are in critical times on the river. Temporary agreements on how to distribute water during times of shortage are expiring. Negotiators have been talking for several years but haven’t been able to agree on anything concrete.

    I’m just an observer, but I’ve been observing fairly closely. Within the limits on how much information I can get as an outsider, I’d like to propose some principles or guidelines that I think are important for the negotiation process.

    A. When Hoover Dam was proposed, the main debate was over whether the federal government or private concerns would operate it. Because the federal option prevailed, water is delivered free to contractors. Colorado River water contractors do not pay the actual cost of water being delivered to them. It is subsidized by the U.S. government. As a public resource, Colorado River water should not be seen as a commodity.

    B. The Lower Basin states of Arizona, California, and Nevada should accept that the Upper Basin states of Colorado, New Mexico, Utah, and Wyoming are at the mercy of Mother Nature for much of their annual water supply. While the 1922 Colorado River Compact allocates them 7.5 million acre-feet annually, in wet years, they have been able to use a maximum of 4.7 maf. During the long, ongoing drought, their annual use has been 3.5 maf. They shouldn’t have to make more cuts.

    C. However, neither should the Upper Basin states be able to develop their full allocation. It should be capped at a feasible number, perhaps 4.2 maf. As compensation, Upper Basin agencies and farmers can invest available federal funds in projects to use water more efficiently and to reuse it so that they can develop more water.

    D. Despite the drought, we know there will be some wet years. To compensate the Lower Basin states for taking all the cuts in dry years, the Upper Basin should release more water beyond the Compact commitments during wet years. This means that Lake Mead and Lower Basin reservoirs would benefit from wet years and Lake Powell would not. In short, the Lower Basin takes cuts in dry years; the Upper Basin takes cuts in wet years.

    E. Evaporation losses (water for the angels) can be better managed by keeping more of the Lower Basin’s water in Upper Basin reservoirs instead of in Lake Mead, where the warmer weather means higher evaporation losses. New agreements should include provisions to move that water in the Lower Basin account down to Lake Mead quickly. Timing is of the essence.

    H. In the Lower Basin states, shortages should be shared along the same lines as specified in the 2007 Interim Guidelines, with California being last to take cuts as Lake Mead water level drops.

    I. On the home front, Imperial Irrigation District policy makers should make a long-term plan to re-set water rates in accord with original water district policy. Because the district is a public, non-profit utility, water rates were set so that farmers paid only the cost to deliver water. Farmers currently pay $20 per acre foot, but the actual cost of delivering water is $60 per acre foot. That subsidy of $60 million comes from the water transfer revenues.

    J. The San Diego County Water Authority transfer revenues now pay farmers $430 per acre-foot of conserved water, mostly for drip or sprinkler systems. Akin to a grant program, this very successful program generated almost 200,000 acre-feet of conserved water last year. Like any grant program, it should be regularly audited for effectiveness.

    K. Some of those transfer revenues should be invested in innovative cropping patterns, advanced technologies, and marketing to help the farming community adapt to a changing world. The Imperial Irrigation District should use its resources to help all farmers be more successful, not just a select group.

    L. Currently, federal subsidies pay farmers not to use water via the Deficit Irrigation Program. We can lobby for those subsidies to continue, but we should plan for when they dry up. Any arrangement that rewards farmers but penalizes farm services such as seed, fertilizer, pesticide, land leveling, equipment, and other work should be avoided.

    M. Though the Imperial Irrigation District has considerable funding from the district’s QSA water transfers, it may need to consider issuing general obligation bonds as it did in its foundational days for larger water efficiency projects such as more local storage or a water treatment plant to re-use ag drain water.

    Much progress has been made in using water more efficiently, especially in the Lower Basin states, but there’s a lot more water to be saved, and I believe collectively that we can do it.

    State leaders seek durable post-2026 plan and make significant contributions

    December 16, 2025

    Las Vegas – California’s water, tribal, and agricultural leaders today presented a comprehensive framework for a durable, basin-wide operating agreement for the Colorado River and highlighted the state’s proposal for conserving 440,000 acre-feet of river water per year.

    At the annual Colorado River Water Users Association conference, California underscored the state’s leadership in conservation, collaboration, and long-term stewardship of shared water resources that inform its approach to post-2026 negotiations.

    California takes a balanced approach, relying on contributions from the upper and lower basins to maintain a shared resource. California supports hydrology-based flexibility for river users, with all states contributing real water savings. Any viable framework would need to include transparent and verifiable accounting for conserved water, along with several other elements outlined in the California framework.

    State leaders also noted that they are willing to set aside many of their legal positions to reach a deal, including releases from Lake Powell under the Colorado River Compact, distribution of Lower Basin shortages, and other provisions of the Law of the River, provided that there are equitable and sufficient water contributions from every state in the Basin and the country of Mexico.

    Constructive California

    “California is leading with constructive action,” said JB Hamby, chairman of the Colorado River Board of California. “We have reduced our water use to the lowest levels since the 1940s, invested billions to modernize our water systems and develop new supplies, partnered with tribes and agricultural communities, and committed to real water-use reductions that will stabilize the river. We are doing our part – and we invite every state to join us in this shared responsibility.”

    Despite being home to 20 million Colorado River-reliant residents and a farming region that produces the majority of America’s winter vegetables, California’s use of Colorado River water is projected at 3.76 million acre-feet in 2025 – the lowest since 1949.

    That achievement comes on top of historic reductions in water use over the past 20 years, led by collaborative conservation efforts. Urban Southern California cut imported water demand in half while adding almost 4 million residents. And farms reduced water use by more than 20% while sustaining more than $3 billion in annual output. Tribes also have made critical contributions, including nearly 40,000 acre-feet of conserved water by the Quechan Indian Tribe to directly support river system stability.

    Going forward, California is prepared to reduce water use by 440,000 acre-feet per year – in addition to existing long-standing conservation efforts – as part of the Lower Basin’s proposal to conserve up to 1.5 million acre-feet per year, which would include participation by Mexico.  When conditions warrant, California is also committed to making additional reductions to address future shortages as part of a comprehensive basin-state plan.

    The state’s history of conservation illustrates what can be accomplished through collaboration, and all Colorado River water users in California are preparing to contribute to these reductions – agricultural agencies, urban agencies, and tribes.

    Framework for a Post-2026 Agreement

    In addition to conservation contributions, California provided a framework of principles for the post-2026 river operating guidelines to advance a shared solution for the seven Basin States, the tribes and Mexico. More specifically, California outlined the following key components for a new framework:

    • Lake Powell releases – California supports a policy of hydrology-based, flexible water releases that protects both Lake Powell and Lake Mead. Flexibility must be paired with appropriate risk-sharing across basins, avoiding disproportionate impacts to any one region.
    • Upper Initial Units (Colorado River Storage Project Act) – Releases should be made when needed to reduce water supply and power risks to both basins.
    • Shared contributions – The Lower Basin’s proposed 1.5 million acre-feet per year contribution to address the structural deficit, including an equitable share from Mexico (subject to binational negotiations), is the first enforceable offer on the table. When hydrology demands more, participation by all seven Basin States is essential.
    • Interstate exchanges – Interstate exchanges need to be part of any long-term solution to encourage interstate investments in new water supply projects that may not be economically viable for just one state or agency.
    • Operational flexibility – Continued ability to store water in Lake Mead is vital to maintain operational flexibility. California supports continuation and expansion of water storage in Lake Mead as a long-term feature of river management and to encourage conservation. We also support Upper Basin pools for conservation, allowing similar benefits.
    • Phasing of a long-term agreement – California supports a long-term operating agreement with adaptive phases. Tools like water storage in Lake Mead and Lake Powell need to extend beyond any initial period due to significant investments required to store conserved water in the reservoirs.
    • Protections and federal support: Any agreement should be supported with federal funding and any necessary federal authorities, allow agriculture and urban areas to continue to thrive, protect tribal rights, and address the environment, including the environmentally sensitive Salton Sea.

    “There are no easy choices left, but California has always done what is required to protect the river,” said Jessica Neuwerth, executive director of the Colorado River Board of California. “We have proven that conservation and growth can coexist. We have shown that reductions can be real, measurable, and durable. And we have demonstrated how states, tribes, cities, and farms can work together to build a sustainable future for the Colorado River.”

    What California agencies are saying:

    “The future of the Colorado River is vital to California – and our nation. As the fourth largest economy in the world, we rely on the Colorado River to support the water needs of millions of Californians and our agricultural community which feeds the rest of the nation. California is doing more with less, maintaining our economic growth while using less water in our urban and agricultural communities. We have cut our water use to its lowest levels in decades and are investing in diverse water supply infrastructure throughout California, doing our part to protect the Colorado River for generations to come. We look forward to continued discussions with our partners across the West to find the best path forward to keep the Colorado River healthy for all those who rely on it.” – Wade Crowfoot, Secretary, California Natural Resources

    “Metropolitan’s story is one of collaboration, of finding common ground. We have forged partnerships across California and the Basin – with agriculture, urban agencies and tribes. And through that experience, we know that we can build a comprehensive Colorado River Agreement that includes all seven states and the country of Mexico. We must reach a consensus. That is the only option.” – Adán Ortega, Jr., Chair, Metropolitan Water District Board of Directors

    “California’s leadership is grounded in results, and the Imperial Valley is proud to contribute to that record. Our growers have created one of the most efficient agricultural regions in the Basin—cutting use by over 20% while supporting a $3 billion farm economy that feeds America. Since 2003, IID has conserved more than nine million acre-feet, and with the Colorado River as our sole water supply, we remain firmly committed to constructive, collaborative solutions that protect America’s hardest-working river.” – Gina Dockstader, Chairwoman, Imperial Irrigation District

    “The path to resiliency requires innovation, cooperation, and every Basin state’s commitment to conservation. The San Diego County Water Authority supports an approach that provides flexibility to adapt to changing climate conditions. That means developing a new framework that allows for interstate water transfers to move water where it’s most needed and incentivizes the development of new supplies for augmentation.” – CRB Vice Chair Jim Madaffer, San Diego County Water Authority

    “Palo Verde Irrigation District is committed to maintaining a healthy, viable river system into the future. We at PVID have always gone above and beyond in supporting the river in times of need. Since 2023 our 95,000-acre valley, in collaboration with Metropolitan and the U.S. Bureau of Reclamation have committed over 351,000 acre-feet of verifiable wet water to support the river system and Lake Mead. It is important to our stakeholders in the Palo Verde Valley and all of California that Colorado River water continues to meet the needs of both rural and urban areas. We must find workable solutions that keep food on people’s plates and water running thru the faucets of homes.” – Brad Robinson, Board President, Palo Verde Irrigation District 

    “California continues to lead in conservation and collaboration, setting the standard for innovation and sustainability. Together, we strive to ensure reliability for millions of people, tribes, and acres of farmland. For decades, CVWD has invested in conservation efficiency, alongside investments from growers. Additionally, we have saved more than 118,000 acre-feet of Colorado River water since 2022 — underscoring our shared commitment to long-term sustainability. CVWD remains dedicated to finding collaborative solutions to protect the river’s health and stability.” – Peter Nelson, Board Director, Coachella Valley Water District

    “As stewards of the Colorado River since time immemorial, our Tribe is committed to protecting the river for the benefit of our people and all of the communities and ecosystems that rely on it. We believe partnerships and collaboration, such as our agreement with Metropolitan Water District and the Bureau of Reclamation to conserve over 50,000 acre-feet of our water in Lake Mead between 2023 and 2026, are essential to ensure that we have a truly living river.” – President Jonathan Koteen, Fort Yuma Quechan Indian Tribe

    “Bard Water District remains committed to continued system conservation and responsible water management. While small in size, the District continues to make meaningful contributions to regional sustainability efforts on the Colorado River.” – Ray Face, Board President, Bard Water District

    “LADWP is dedicated to delivering and managing a water supply that prioritizes resilience, high quality, and cost-effectiveness. These investments illustrate that achieving urban water resiliency is indeed feasible.” – Dave Pettijohn, Water Resources Director, Los Angeles Department of Water & Power

    🥵 Aridification Watch 🐫

    A new report from the Colorado River Research Group, aptly named “Dancing with Deadpool,” 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 — 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 river’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, “Think Natural Flows Will Rebound in the Colorado River Basin? Think Again.”

    Natural flows — which is a calculation of how much water would pass Lees Ferry without upstream human intervention — 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 authors call the Southwest “megadrought country,” since tree rings and other sources show that severe, multi-decadal dry spells — like the one gripping the region currently — have occurred somewhat regularly over the last 2,000 years. The current drought, then, is likely a part of this natural climate variability.

    But there’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, it’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 a paper they put out in September, they find that if water year 2026 (which we’re about 2.5 months into) is anything like water year 2025, Lake Powell is in trouble, and “low reservoir levels in summer 2026 will challenge water supply management, hydropower production, and environmental river management.”

    The top water users on the Lower Colorado River Basin. Imperial Irrigation District in southern California once again tops the list. But it’s notable how much consumption they’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 Nevada’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 — independent of whatever agreement the states come up with for dividing the river’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. That’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.

    That’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 report’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 “buy-and-dry” proposition, where a city buys out the water rights of farms to serve more development. That doesn’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 — and the farmers — from the community. There would also be the question of how to manage the freshly fallowed fields so that they don’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 report’s second chapter, although it’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 …

    The News: Colorado Parks and Wildlife last week thanked New Mexico wildlife officials for successfully capturing gray wolf 2403, a member of Colorado’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 — i.e. the “natural” state — or are they running a zoo? 

    The CPW said that the wolf’s capture was in compliance with an agreement with bordering states that is purportedly intended to “protect the genetic integrity of the Mexican wolf recovery program, while also establishing a gray wolf population in Colorado.”

    I’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 that’s a good thing. And trying to confine the wolves to artificial and arbitrary political boundaries is counterproductive.

    “Historically, gray wolf populations in western North America were contiguously distributed from northern arctic regions well into Mesoamerica as far south as present day Mexico City” explained David Parsons, former Mexican Wolf Recovery Coordinator for the US Fish and Wildlife Service in a written statement. “The exchange of genes kept gray wolf populations both genetically and physically healthy, enhancing their ability to adapt and evolve to environmental changes.” He added that 2403’s walkabout, along with that of “Taylor,” the Mexican gray wolf that has defied attempts to constrain him to southern New Mexico by traveling into the Mt. Taylor region, were “simply 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.”

    Amen to that. 

    It’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.

    December 15, 2025

    Key Points

    • Seven states and 30 tribes that depend on the Colorado River are looking for ways to share a shrinking resource, but environmental groups fear little will be left for the river itself.
    • A wetlands at the end of the river and a fishery at its midpoint show what can happen when water is managed to preserve nature’s needs.
    • Growing demand on the river and competing interests, including electric power providers, could force negotiators for the states to confront difficult decisions.

    CIÉNEGA DE SANTA CLARA, Mexico — The rusty observation tower at the edge of this wastewater-fed marsh offers an osprey-eye view of two possible futures for the parched and overworked Colorado River. To one side, the marsh spreads across more than 20 square miles of pools and islands choked with cattails and phragmites, convoys of pelicans descending and splashing down for a rest on their journey south from the Great Salt Lake or other western waters. Dragonflies hover below, while a fish hawk circles above, scanning the open water between the reeds. This is a vision of a future in which partners across the Western United States and Mexico save enough water that they can spare some for nature, even if it means irrigating it with the salty dregs. On the tower’s other side, boundless flats of sand and cracked mud spread to the horizon across what was, prior to the river’s damming a century ago, one of Earth’s great green estuaries.

    Jennifer Pitt leaned against a rail atop the tower and scanned that dusty horizon. A century ago, she said, the river had meandered so widely and soaked so much verdant ground there that the naturalist Aldo Leopold had written in “A Sand County Almanac” that “the river was nowhere and everywhere,” unable to “decide which of a hundred green lagoons offered the most pleasant and least speedy path to the Gulf (of California).”

    Now the Grand River’s delta supports just a handful of green lagoons, all fed either by wastewater or by targeted environmental irrigation. Pitt leads the Audubon Society’s Colorado River program. She has toiled for decades alongside American and Mexican conservationists to rebuild slivers of living delta from what’s left of the water after dams, farm ditches and growing cities divert most of the great river along its 1,450-mile route from the Rocky Mountains toward its dry mouth on the Sea of Cortez near here. A century ago, the river would have wandered a soaked delta teeming with birds, jaguars and legendary biodiversity. Now, a wastewater marsh must do the ecological heavy lifting.

    “If we can’t prioritize taking care of a place like this, I fear for our ability to take care of ourselves,” Pitt said.

    The next few months will be a turning point in efforts to preserve a measure of nature here and across the river’s length, as the seven U.S. states that split the bulk of the water struggle to reach a new deal among themselves that could also determine how much water is available to nurse a remnant of the river’s own environment. Federal officials have said Interior Secretary Doug Burgum is prepared to impose his own cuts if the states can’t reach their own deal, and have said they need a negotiated plan by late winter to avoid that outcome. More than two decades of “megadrought,” unprecedented in U.S. history, have left little wiggle room for year-to-year operations. Reservoirs that were near their 58.48 million-acre-foot capacity in 2000 began the 2026 water year on Oct. 1, with just 21.8 million acre-feet behind the dams. Each acre-foot contains about 326,000 gallons and is roughly enough to support three households for a year, though the bulk of the water flows to the region’s farms.

    New ‘book’ explores the evolving thoughts about an increasingly dire situation

    To put that into perspective, the Colorado River Compact assumed an average 16.5 million acre-feet at that site, Lees Ferry. The river this century has produced far less. Since 2020, the river flows have declined even more, to an average of 10.8.

    Might it get worse?

    “Dancing With Deadpool,” a new product from the Colorado River Research Group, delivers the short answer.

    “Another year or two of low inflows and we will completely blow through the cushions provided by reservoir storage,” says the document’s executive summary. The word “crisis” litters the 64-page production. It has eight chapters written by 22 authors from Colorado and three other Colorado River Basin states.

    The Colorado River has fascinated journalists since at least the 1980s. Then, the river was still delivering water to Mexico’s Sea of Cortez but troubles were evident on the horizon. The river now, except for specially engineered releases from upstream dams, disappears entirely after crossing into Mexico.

    Since 2022, the Colorado River had become a national story. Empty seats at the annual Colorado River Water Users Association conference in Las Vegas have disappeared, press credentials harder to secure.

    The tension even in the last year has grown. The river runoff this year was only 55% of long-term average. The seven basin states remain at an impasse about solutions proportionate to the problem.

    “We have now entered a new era: Dancing with Deadpool,” says the report.

    Deadpool is the point at which reservoirs can release no water. In 2022, that moment seemed imminent as sandstone walls of Glen Canyon were exposed directly to sunlight after being submerged since shortly after Lake Powell began filling. Then a miracle winter arrived, water levels in the two big reservoirs, Powell and Mead, rose once again, the emergency receded.

    Now the crisis is back — and looming larger.

    You can scare yourself to death with what-ifs, but we may need something akin to a miracle to avoid full-blown crisis. We cannot have another winter and then runoff like 2002-2003. Or, as several authors point out, runoff like we had in 2025.

    As it is, we need another miracle winter, something akin to what diehard Denver Broncos fans remember as “the drive” in a 1987 playoff game. John Elway led his football team 98 yards down the field in Cleveland to tie the game with 37 seconds left. They won in OT.

    Brad Udall and Jonathan Overpeck warn against too much optimism. Mother Nature can be stingy. She has been in the past, with one drought period as long as 80 years during the last 2,000 years. Now, the evidence grows that our monkeying with Mother Nature has produced this drought.

    In 2017, Udall and Overpeck issued the results of their study that showed that warming alone was responsible for roughly half of the reduced natural flows of the Colorado River, at that point 17%. They delivered a new phrase: “hot drought” as distinguished from “dry drought.” The warmer temperatures were robbing the Colorado River Basin of water.

    Precipitation in the basin has also declined 7% in the 21st century, as compared to the 20th century. In their chapter, Udall from Colorado State and Overpeck now at the University of Michigan (but with a summer cabin in San Miguel County), cite two new studies that together provide evidence “suggesting” complicity of humans. Greenhouse gases explain the declined precipitation, too.

    As science is never 100%, Udall and Overpeck use cautious language. The studies, they say, “strongly suggest we are in for extended dry periods in the Colorado headwaters in the decades ahead.”

    If there is less water, then isn’t the solution simple? Use less!

    Easy to say. And for the last 20 years, efforts have been made to nibble away at uses. Cities have been working to make less water-intensive urban landscapes popular. But the far larger story lies in agriculture.

    In Colorado and the three upper basin states, for example, about 70% of all the Colorado River water (after trans-basin diversions for irrigation are accounted for) goes to agriculture. How can ag use less water?

    Two of the chapters work on this. A trio of academics from Wyoming and one from Colorado take aim specifically at the upper basin states. “The relevant questions are not whether or when cuts will happen, but how deep will they go, how will they be distributed, and how well can the consequences be mitigated?” they ask.

    The four upper-basin researchers argue that evidence already exists for success. With creativity and collaboration, they say, farmers and ranchers can sustain crop and livestock production even as water becomes scarce. They get into the details, talking about adjustments of cow-calf operation, for example, to reduce water-dependent needs.  They call for more research into limited irrigation, crop switching and other practices.

    Two other academics, both from Arizona State, take a somewhat broader view, acknowledging the challenge.

    “In a landscape of poor choices, in a failing river system in which all solutions are deeply unpopular to some or other powerful constituency, potentially harmful to one community or another or inordinately expensive and founded on unreliable funding, it is at least worth considering another option,” write Kathryn Sorensen and Sarah Porter.

    They see cuts of up to 4 million acre-feet in the basin annually being necessary. Again, that’s about 25% of what those who created the Colorado River Compact expected would be annual flows for the seven basin states.

    How to get there? They introduce a new concept, “economic water productivity,” a measure of the value of water. Instead of buy and dry programs, they see need for a federally financed effort to pivot uses through incentives to reduce water use on those agricultural lands.

    Similar buy-down of high-volume irrigated agriculture is underway in two groundwater depletion areas in Colorado, the San Luis Valley and the Republican River Basin. Some federal money is providing help in the latter basin. They contend federal money will be needed, and lots of it, to pay for this big pivot in the Colorado River Basin. That, they say, would be fitting, because it was federal money that financed the infrastructure for this hydraulic empire.

    As for groundwater, that part of the Colorado River story has been generally overlooked. A study released several months ago found that nearly two-thirds of storage — both surface and groundwater — lost from 2002 to 2024 in the Colorado River actually came from groundwater depletion, mostly in Arizona.

    Whoa!

    “Simply shifting unsustainable surface water uses to unsustainable groundwater uses does nothing to address the core mismatch of supplies and demands,” observes Doug Kenney, who directs the Western Water Policy Program at University of Colorado Law School.

    Other contributors dissect the complexities of what would seem to be simple, common sense solutions. For example, Eric Kuhn, the former general manager of the Colorado River District, works through the concept of water sharing among the states based on a percentage basis. The Colorado River Compact divides water between the upper and lower basins, a mistake in retrospect although even in 1922, when it was adopted, there had been an argument for using a percentage.

    Later, when the upper-basin sates adopted a compact among themselves, they did use a percentage basis.

    Kuhn goes deep into the history, as he has done with book-writing (“Science be Dammed,” 2019, with John Fleck) to sort through the thinking of this idea over the last century. It came up again earlier this year as the seven basin states tried to figure out how to share the river given the changed realities. The states, however, could not agree on what percentages should be used for sharing. It may have been just too much of a transformational change for some states to accept, he says.

    However, the idea may come back if the stalemate between the upper and lower basins of the Colorado River ends up in the federal courts. Or failing that, what exactly would federal intervention look like? That’s an impolite question, but one of those what-ifs that must be wondered about. (For the record, the water people I know seem to have high regard for people in the Department of Interior in charge of looking after the Colorado River).

    The large story here is that the states, with enormous aid from the federal treasury, created the infrastructure and expectations of water that no longer exists and, as per the studies of scientists, will almost certainly not return within the lifetimes of any of us. What, then, should be the federal role in defining the future balance? Once again, might the dismantling of Glen Canyon Dam be such a wild idea after all?

    Thoughts in this book will likely be part of the conversations next week in Las Vegas when representatives of the seven basin states gather, as they always do, at the Colorado River Water Uses Association conference. Might a hallway conversation lead to a breakthrough?

    Like huge snowstorms in the Rockies and then cool temperatures during runoff, there might be miracles, but I wouldn’t count on it. This deadpool dance might end sooner than anybody actually likes.

    The Erosion of the Colorado River “Safety Nets” 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 “safety nets,” defined broadly, is happening at a pace far surpassing the already unprecedented declines in reservoir storage. Presumably that’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?

ΔS/Δt 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 tools—namely NASA’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 storage—both surface and groundwater—lost in the Colorado River Basin actually came from groundwater depletions.2 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 pumping—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 “efficiency.” It’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 programs—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 “re-carbonize” (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.5 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, it’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 ”worked” to keep deliveries flowing for so long—except, of course, for the tribes and the environment—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 resigned—and almost “comfortable”—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 basin’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 wouldn’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 invoked—a Congressional rewrite of river allocation and management—either before or after the litigation concludes. In this setting, the extreme disparity in political influence—as measured by the number of Congressional representatives—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, you’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 Powell—the basin’s primary risk management tools—increasingly flirt with deadpool. But at the basin scale, that’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 that’s far from a comprehensive or integrated approach, and safety nets designed by and for the “established players” only deepen the inequities that increasingly divide the Colorado River community.

    There’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, it’s also not a bad idea to remember that poor risk management often comes at expense of diminished equity—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, I’m inclined to think we are rowing in the wrong direction. ●

The President’s 2026 budget request cuts Reclamation’s budget approximately by a third (Fiscal-Year-2026-Discretionary-Budget-Request.pdf (see page 28 and Table 2); Briefly: Budget proposal defunds Western water conservation grants – Water Education Colorado). Overall, proposed cuts to the Department of Interior total over $5 billion, or 30.5% of the 2025 enacted budget (Table 2). To this point, that request has not been embraced by Congress.

    4 For example, within NOAA, the administration’s 2026 budget request “terminates a variety of climate-dominated research, data, and grant programs,” and “cancels contracts for instruments designed for unnecessary climate measurements,” while also cutting National Science Foundation support of research “with dubious public value, like speculative impacts from extreme climate scenarios” (Fiscal-Year-2026-Discretionary-Budget-Request.pdf; see pages 24-25, and 38).

    December 9, 2025

    The year is ending with the Colorado River at a critical juncture.

    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. It’s a risky move that no one in principle seems to want. Yet brinkmanship and entrenched positions have stymied compromise.

    The basin’s Indian tribes, which collectively have rights to more than a quarter of its recent average annual flow, are adamant that their interests – and more broadly, the river itself – be protected. “Any 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,” 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.

    Here’s the preface:

    Welcome to the Colorado River Research Group’s (CRRG) 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 “Individual Submissions” 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 individual—or, in several cases, the product of small groups—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 CRRG’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? That’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 isn’t working. — Doug Kenney, CRRG Chair

    Romancing the River: Why am I ‘Romancing’ It? — George Sibley (SibleysRivers.com) #ColoradoRiver #COriver #aridification

    The Demilitarized Zone between the two Koreas – it’s not quite this bad between the two Colorado River Basins.

    December 2, 2025

    Negotiations among the Magnificent Seven representing the seven states of the Colorado River region begin to resemble the ongoing negotiations between the military and diplomatic representatives for North and South Korea, where negotiations for something beyond an armistice have been going on for more than sixty years. Here, as there, the negotiations have reached a stalemate, and both sides are now engaged in an information war. Between the two Koreas, this war takes the form of everything from huge arrays of speakers blasting pop music across the demilitarized zone to smuggled USB drives with movies and TV shows. Here, it is mostly just propaganda bombs tossed over our ‘DMZ,’ the Grand Canyons, about each side’s virtue and the other side’s obstinacy, depending on their regional media’s love of conflict and tendency to support the home team. The missed November deadline has been seamlessly replaced – as we all suspected it would be – by a February deadline. But otherwise – nothing new on that front. We can just hope it doesn’t go on for another fortysome years.

    So I’m going to take advantage of the stalemate to ask the reader to think about a bigger picture that may be more interesting. It stems from a comment from my partner Maryo, from whom I learn too much to dismiss anything she says. ‘Why are you “romancing the river”?’ she asked the other day. ‘Romance is such a cheapened concept today – bodice-ripping stories of ridiculous antagonistic love. You’re undermining the value of your work, calling it a “romance.”’

    ‘Well,’ I said – figuring that if she feels that way, maybe my readers raise the same question – ‘maybe one of the things a writer ought to try to do is restore the value of words and the concepts they once represented that have become devalued through misuse.’ Spoken like a true Don Quixote, another old man who took arms, sort of, against abuse of the concept of ‘romance.’

    I do think that one of the things that ‘civilization’ does in civilizing us is to simplify things for us, including words whose complexity and depth embrace concepts, ideas and feelings that can be inconvenient to an orderly civilized society. A  ‘romance,’ from the medieval era on into the early 20th century, was a story of an adventure in pursuit of something mysterious, exciting, challenging, something beyond everyday life. That could be the pursuit of a love relationship that was life-changing (and maybe life-endangering) for its participants – Tristan and Isolde, Launcelot and Guinevere, Romeo and Juliet, Bonnie and Clyde.

    But on a much larger scale, the romantic adventure can be establishing a relationship with anything outside of ourselves that intrigues or challenges us. The relationship can emerge with a place, a house, a horse, a car, a continent, a river, an idea, as well as another person, anything that intrigues us, wakes up our imagination – arational or prerational relationships that make the civilizing forces nervous. The relationship can run the quick dynamic spectrum from arational love to its flip side arational hate, through all the intermediary love-hate variations. It can also have a mythically selective or even creative attitude toward the gray-zone relationship between ‘truth’ and fact. Which leads those trying to develop an orderly civilization to dismiss anything (ad)venturing into the mythic as a lie. It just seems simpler that way.

    The first comprehensive study of the Colorado River region was uncivilized enough to state upfront its romantic origins: Frederick Dellenbaugh’s Romance of the Colorado River. Dellenbaugh’s book (available online for a pittance) delved as deeply as was possible at that time into both the First People prehistory in the region and the early history of the Euro-American invasion, from the Spanish trying to work their way up the river from its contentious confluence with the Gulf of California (‘Sea of Cortez’ to them) to the trappers imposing the first major Euro-American change on the river, stripping its tributaries of their beavers which increased the size and violence of the river’s annual spring-summer runoff of snowmelt. But the heart of the book is John Wesley Powell’s explorations to link the upper river and the lower river through its canyons.

    Dellenbaugh, as a seventeen-year-old, accompanied Powell on his second Colorado River expedition, a ‘baptism under water’ (often literally) that shaped his ‘romantic’ vision. In his ‘Introduction,’ after observing that most of the great rivers that humans encountered in exploration and settlement gradually became like foster parents to those who settled along them, carrying goods for them and generally watering and growing their settlements, he says of the Colorado:

    Dellenbaugh’s Romance was published in 1903. That same year, another great southwestern writer, Mary Hunter Austin came out with her Land of Little Rain, a fascinating 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 ‘romancing the river,’ in an observation about a small Arizona tributary of the Colorado River, ‘the fabled Hassayampa… of whose waters, if any drink, they can no more see fact as naked fact, but all radiant with the color of romance.’

    I will now indulge my tendency to take a ‘tectonic’ look at history – looking for large chunks colliding or grating together or subducting under each other. I see the history of our engagement with the Colorado River dividing into three ‘tectonic romances’:  first, the Romance of Exploration, which is chronicled in a couple different ways by those two explorers, Dellenbaugh and Austin; their 1903 publications summarize that age and put a semi-colon at the end of the period, as it were.

    Second, the Romance of Reclamation: 1903 also marks the year the U.S. Reclamation Service came into being, an organization created almost specifically for settling the Colorado River deserts. Civilized people on both sides of the question would deny that there was any ‘romance’ to reclamation, but one early Bureau engineer would publicly disagree, writing in 1918 about ‘the romance of reclamation’:

    C.J. Blanchard of the U.S. Reclamation Service authored that steaming verdure. The Service at that time was under the U.S. Geological Survey, a scientific organization disciplined to the ‘look before you leap’ methods of science, discerning the reality of a situation and adapting to that; but the Reclamation Service, frustrated by the seasonal flood-to-trickle flows of the Colorado, thought that changing that reality (through storage and redistribution) was a more promising route than adapting to it, and so was on its way to becoming independent of the USGS when Blanchard wrote his ‘romance of irrigation’ for an educational journal called The Mentor(thanks, Dave Primus, for calling it to my attention).

    The best-known document of the Romance of Reclamation was of course the Colorado River Compact – a document in which the romance of reclamation overrode any relationship to ‘naked fact’ about the river and its flows, a situation that is now biting our collective ass. Yet an Arizona water maven said recently that any Bureau of Reclamation solution to the seven-state impasse would have to cleave closely to the Compact…. The history of the Romance of Reclamation has been written in the gaggle of Congressional acts, court decisions, treaties, regulations and directives that make up the ‘Law of the River’ (recitations of which never seem to include the 1908 Winters Doctrine allocating assumed water to federal reservations, including to the First Peoples).

    The end of the Romance of Reclamation would be in the 1960s, pick your date: publication of Rachel Carson’s Silent Spring in 1962, passage of the Wilderness Act in 1964, passage of the Environmental Policy Act in 1969 – a decade in which the general American perception of the West underwent a sea change, from seeing it as a workplace for producing the resources to feed the American people and industries, to seeing it as a great natural playground to which America’s predominantly urban population could go to recharge, with a resulting desire to protect it from the very industrial consumption that supported the American ‘lifestyle.’.

    This was the dawn of the third romantic epoch in our relationship with the river (and the continent in general) – the Romance of Restoration and Revision, driven by a belief that we have sinned against capital-N Nature – with many naked facts as evidence – and can only expiate our sins by preserving what remains of the nonhuman environment, restoring what we can of the damage we’ve done, and revising our own systems for consuming nature (e.g., renewable energy).

    Aesthetics are at the root of our romance with capital-N Nature, aesthetics best served by the (increasingly rare) opportunity to be alone with and ‘silent on a peak in Darien,’ as Keats put it. We have a large (and growing) number of excellent writer[s] who work to elaborate on that aesthetic – Ed Abbey first, Craig Childs, Heather Hansman, Kevin Fedarko, to name a few.

    But the aesthetic yearning to ultimately ‘put it back the way it was’ does not extend to other equally naked facts, like the dependence of the outdoor recreation industries on the creation of big mountain-highway traffic jams pumping big quantities of carbon and nitrogen gases into the already overladen atmosphere, as we all load up our cars with expensive gear to go off to commune with Nature. Or the naked fact that maintaining civilization-as-we-know-it for 300 million people involves a lot of nonrewable extraction from Nature that it will be very difficult to move away from entirely – unless we figure out how to control our breeding.

    Just as significant achievements were achieved under the Romance of Reclamation, so significant achievements have been achieved under the Romance of Restoration and Revision – the setting aside of millions of acres of still-sort-of-wild land, instream flow laws, increasingly responsible forest management, et cetera. But we are clearly still in the early transition – half a century later – to a more realistic romance with restoring and revising to a kinder gentler relationship with the nonhuman systems of nature. And right now, we  are experiencing a major counter-attack from the societal forces whose aesthetics still imagine a ‘working landscape’ of derricks, mines and other industrial-scale harvests, all suffused with the ‘smell of money,’ societal forces that believe the best of times were before we woke up to the increasingly fragile finitude of our planet under the burden of us. Let’s all go back and make America great again!

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.

    I cannot now imagine when and how this third epoch of our romance with the river will end. I think this aesthetic romance might peak with the ‘breaching’ of Glen Canyon Dam, an action that has taken on a somewhat mythic quality for today’s river romantics. I don’t think we will tear it down – let it stand as a monument to…something. But I suspect that even the Bureau of Reclamation is exploring some way of tunneling around it at river level, as we continue to flirt with the disaster of dead pool behind the dam. It will not be easy, due to the silt already piled up at the dam – but really, nothing is going to be easy anymore; that blessed civilization is now in the rear-view mirror.

    I’m going to take advantage of the lull in the short-term news about the river’s management for maybe the next decade, to take a look at each of these three epochs of ‘romancing the river’ and their relationship to the ‘naked facts’ of the river – mostly see if there might be something there we’ve overlooked that might help us move forward in our ever-emerging relationship of this ‘First River of the Anthropocene.’ Onward and outward.

    Study: Something’s gotta give on the #RioGrande: #ClimateChange and overconsumption are drying up the Southwest’s “other” big river — Jonathan P. Thompson (LandDesk.org)

    🥵 Aridification Watch 🐫

    The Colorado River and its woes tend to get all of the attention, but the Southwest’s “other” big river, the Rio Grande, is in even worse shape thanks to a combination of warming temperatures, drought, and overconsumption. That’s become starkly evident in recent years, as the river bed has tended to dry up earlier in the summer and in places where it previously had continued to carry at least some water. Now Brian Richter and his team of researchers have quantified the Rio Grande’s slow demise, and the conclusions they reach are both grim and urgent: Without immediate and substantial cuts in consumption, the river will continue to dry up — as will the farms and, ultimately, the cities that rely on it.

    The Rio Grande’s problems are not new. Beginning in the late 1800s, diversions for irrigation in the San Luis Valley — which the river runs through after cascading down from its headwaters in the San Juan Mountains — sometimes left the riverbed “wholly dry,” wrote ichthyologist David Starr Jordan in 1889, “all the water being turned into these ditches. … In some valleys, as in the San Luis, in the dry season there is scarcely a drop of water in the riverbed that has not from one to ten times flowed over some field, while the beds of many considerable streams (Rio la Jara, Rio Alamosa, etc.) are filled with dry clay and dust.”


    Rio Grande Streamflow Mystery: Solved? — Jonathan P. Thompson


    San Luis Valley farmers gradually began irrigating with pumped groundwater, allowing them to rely less on the ditches (but causing its own problems), and the 1938 Rio Grande Compact forced them to leave more water in the river. While that kept the water flowing through northern and central New Mexico, the Rio Grande’s lower reaches still occasionally dried up.

    Then, in the early 2000s, the megadrought — or perhaps permanent aridification — that still plagues the region settled in over the Southwest. [ed. emphasis mine] Snowpack levels in the river’s headwaters shrank, both due to diminishing precipitation and climate change-driven warmer temperatures, which led to runoff and streamflows 17% lower than the 20th century average, according to the new study. And yet, overall consumption has not decreased.

    “In recent decades,” the authors write, “river drying has expanded to previously perennial stretches in New Mexico and the Big Bend region. Today, only 15% of the estimated natural flow of the river remains at Anzalduas, Mexico near the river’s delta at the Gulf of Mexico.” Reservoirs, the river’s savings accounts, have been severely drained to the point that they won’t be able to withstand another one or two dry winters. As farmers and other users have increasingly turned to groundwater pumping, aquifers have also been depleted. The situation is clearly unsustainable.

    Something’s gotta give on the Rio Grande, and while we may be tempted to target Albuquerque’s sprawl, drying up all of the cities and power plants that rely on the river wouldn’t achieve the necessary cuts.

    Source: “Overconsumption gravely threatens water security in the binational Rio Grande-Bravo basin” by Brian Richter et al.

    It will come as little surprise to Western water watchers that agriculture is by far the largest water user on the Rio Grande — taking up 87% of direct human consumption — and that alfalfa and other hay crops gulp up the lion’s share, or 52%, of agriculture’s slice of the river pie. This isn’t necessarily because alfalfa and other hays are thirstier than other crops, but because they are so prevalent, covering about 433,000 acres over the entire basin, more than four times as much acreage as cotton.

    Source: Overconsumption gravely threatens water security in the binational Rio Grande-Bravo basin

    This kind of math means farmers are going to have to bear the brunt of the necessary consumption cuts — either voluntarily or otherwise. In fact, they already have: Between 2000 and 2019, according to the report, Colorado lost 18% of its Rio Grande Basin farmland, New Mexico lost 28%, and the Pecos River sub-basin lost 49% (resulting in a downward trend in agricultural water consumption). Some of this loss was likely incentivized through conservation programs that pay farmers to fallow their fields. But it was also due to financial struggles.

    Yet even when farmers are paid a fair price to fallow their fields there can be nasty side effects. Noxious weeds can colonize the soil and spread to neighbors’ farms, it can dry out and mobilize dust that diminishes air quality and the mountain snowpack, and it leaves holes in the cultural fabric of an agriculture-dependent community. If a field’s going to be dried up, it should at least be covered with solar panels.


    Think like a watershed: Interdisciplinary thinkers look to tackle dust-on-snow — Jonathan P. Thompson


    Another possibility is to switch to crops that use less water. This isn’t easy: Farmers grow alfalfa in the desert because it’s actually quite drought tolerant, doesn’t need to be replanted every year, is less labor-intensive than other crops, is marketable and ships relatively easy, and can grow in all sorts of climates, from the chilly San Luis Valley to the scorching deserts of southern Arizona.


    Alfalfaphobia? Jonathan P. Thompson


    Still, it can be done, as a group of farmers in the San Luis Valley are demonstrating with the Rye Resurgence Project. This effort is not only growing the grain — which uses less water than alfalfa, is good for soil health, and makes good bread and whiskey — but it is also working to create a larger market for it. While it’s only a drop in the bucket, so to speak, this is the sort of effort that, replicated many times across the region, could help balance supply and demand on the river, without putting a bunch of farmers out of business.

    Oh, and about that other river? You know, the Colorado? Representatives from the seven states failed to come up with a deal on how to manage the river by the Nov. 15 deadline. The feds had mercy on them, giving them until February to sort it all out. I’m not so optimistic, but we’ll see. Personally, I think the only way this will ever work out is if the Colorado River Compact — heck, the entire Law of the River — is scrapped, and the states and the whole process is started from scratch, this time with a much better understanding of exactly how much water is in the river, and with the tribal nations having seats at the table.


    ⛏️ Mining Monitor ⛏️

    There are a bunch of wannabe uranium mining companies out there right now, locating claims and acquiring and selling claims and touting their exploratory drilling results. But there are only a small handful of firms that are actually doing anything resembling mining. One of them is the Canada-based Anfield, which just broke ground on its Velvet-Wood uranium mine in the Lisbon Valley, even without all of the necessary state permits. 

    Now Anfield says it has applied for a Colorado permit to restart its long-idle JD-8uranium mine. The mine is on one of a cluster of Department of Energy leases overlooking the Paradox Valley from its southern slopes, and was previously owned and operated by Cotter Corporation. The mine has not produced ore since at least 2006. Anfield says it will process the ore at its Shootaring Mill near Ticaboo, Utah, which has yet to get Utah’s green light.

    November 21, 2025

    The states that share the Colorado River have failed to agree on how to protect it, leaving 35 million people without a clear path forward. We still have a chance to protect the river – but we must act now. Our communities need a plan that responds to climate change, proactively prepares for water shortages, promotes conservation across the Basin, and protects river health.

    • One in 10 Americans depend on a healthy Colorado River. For the last two years, their future has been hotly debated behind closed doors.
    • The states that share the river have failed to agree on how to protect it, missing a critical deadline to provide a plan for managing the river – leaving our communities high and dry.
    • It’s time to put the river before politics. Our communities need results and a plan that saves water across the West.

    One in 10 Americans, along with countless fish and wildlife, depend on a healthy Colorado River. For years, our future has been hotly debated by a handful of state officials behind closed doors. The river has faced escalating threats from climate change and unsustainable water demands. River flows are declining, and our two major reservoirs are less than one-third full. That is why it was so disappointing when officials finally emerged from two years of negotiations empty-handed.

    The guidelines for managing the Colorado River expire in 2026, and the Bureau of Reclamation has been working with the Basin states, Tribes, and stakeholders on a new plan for the dry years ahead. Reclamation gave the states until Nov. 11 to outline their framework for the new guidelines with the details due Feb. 14.

    What is the hold up? The Colorado River Basin states are divided into two camps — the Lower Basin (Arizona, California, and Nevada) and the Upper Basin (Colorado, New Mexico, Utah, and Wyoming). The two Basins are at odds over a variety of fundamental issues, including who should take water shortages, how much these should be, and whether shortages are mandatory or voluntary. The Lower Basin has agreed to take the majority of the shortages in most years, but there is significant disagreement over who bears responsibility for the remaining shortages. Both Basins argue that the other is responsible. The threat of interstate litigation over the river looms large. These court battles would take decades to resolve, cost millions of dollars, and plunge the region into a state of uncertainty — all while the river system continues to crash.

    The states held numerous confidential meetings in an attempt to reach an agreement while communities throughout the West anxiously awaited the outcome. On Nov. 11, the states released a joint statement that offered a commitment to continue negotiating, but little else.

    The Colorado River is not going to wait for process or politics. Drought and climate change are reshaping the West. The window to secure the river’s future is closing fast. 

    Decision makers need to start making real progress. If we have another dry year like this one, water demands could exceed the river’s natural flow by 3.6 million acre-feet, which is enough water to sustain over 7 million families for an entire year. Such a shortfall could mean water levels in Lake Powell drop so low that Glen Canyon Dam can no longer produce hydropower and it raises serious concerns about whether the dam can safely operate at all.

    This problem is too big for one state or sector to solve on its own. Everyone in the Basin must do more to save water and protect the river. Every drop matters.

    Decision makers are trying to solve a complex problem with difficult trade-offs, but the challenges will only grow with each passing day.  We simply can’t do our best work if we wait until the last minute. A plan that is hastily put forward at the eleventh hour leaves little room for public input or creative solutions. Instead, it risks perpetuating a status quo that hasn’t been working for anyone.

    We must allow time to incorporate input from the 30 Basin Tribes, many of whom have long been excluded from key negotiations and lack access to clean water. We also need to leave room to build in solutions that protect the health of the river that sustains the West.

    The future of our region — from families in Denver to raft guides in Moab to communities on the Navajo Nation to farmers in Yuma — depend on a healthy river.

    We need a plan for the dry years ahead, and we need it now. While state negotiations remain important, the Bureau of Reclamation cannot let the ongoing impasse stand in the way of meaningful solutions.  Reclamation must press on and work with Tribes and stakeholders across the West to develop robust and equitable guidelines that protect the river we all depend on.

    At WRA we are continuing to advocate for policies that:

    • Base management decisions on the best available science, including how much water is actually flowing in the river
    • Expand water conservation efforts across the Basin and create flexible water storage accounts so that we can store water to protect river health and meet our needs in dry years
    • Ensure Tribes have meaningful opportunities to shape decisions on the river and can access their fair share of the river’s water
    • Invest in projects to maintain the river’s infrastructure, incentivize water conservation, build water security, and restore irreplaceable fish and wildlife habitat
    • Enable ongoing collaboration across the region
    • Adopt policies that prioritize the health of the river so that future generations can build a life in the West

    The next few months will determine the future of the river for years to come. By the end of this year, Reclamation is expected to publish a draft environmental impact statement analyzing alternatives for managing the river. This will be followed by a public comment period where you can make your voice heard. Reclamation’s final record of decision is expected late next summer.

    We are up against hard deadlines enforced by the federal government and Mother Nature. The clock is ticking. We still have a chance to protect the river — but we must act now.

    Colorado water transfers rarely come easily. State water law ensures that every last drop of water is accounted for, litigated, and litigated some more.

    It is no surprise then that the attempted Shoshone purchase by the Colorado River Water Conservation District has snagged on a couple of thorny legal and policy issues. Whether those issues will prove fatal to the purchase will be taken up at a meeting tomorrow afternoon, Nov. 19, in Golden.

    The Shoshone rights

    The transferred water rights from Xcel Energy to the Glenwood Springs-based River District have huge implications. Xcel uses the water rights for hydroelectric production at the Shoshone plant in Glenwood Canyon. The hydro plant produces relatively little power. As in real estate, though, location matters entirely.

    Xcel’s water rights of 1902 and 1929 are senior to most other water rights upstream of Glenwood Canyon. They are also high-volume water rights, at 1,250 and 158 cubic feet per second, respectively. Additionally, they are entirely non-consumptive, meaning that all water taken out of the river (to spin the turbines) soon returns to the river for downstream use. As such, they have tremendous power to influence flows along the entirety of the Colorado River through Colorado.

    If Xcel were to cease making electricity there, junior users upstream could divert more water. Many of those users would be the state’s transmountain diversions, which extend from Rocky Mountain National Park to Independence Pass. They benefit farmers and now mostly cities from Fort Collins to Colorado Springs. Any water that is diverted to the Front Range, however, is water that does not flow westward.

    Because of this, both the River District and the Front Range diverters have had their eyes on those water rights for decades. What happens at Shoshone matters greatly both on the Western Slope, where the river naturally flows, and on the Front Range, where some of the river is now diverted.

    Will the River District get that water right? It plans to keep the senior, high-volume hydropower water rights but also add an environmental instream flow right to the original decree, a class of water right approved by state legislators in 1973.

    The district has already inked a purchase-and-sale agreement with Xcel and has raised $57 million of the $99 million price. It has been promised an additional $40 million from the Bureau of Reclamation, although the Trump administration has now frozen that money.

    The Colorado Water Conservation Board (CWCB), a state agency responsible for water policy and funding, plays several major roles. In addition to agreeing to contribute $20 million, the CWCB has the sole authority under state law to own instream flow rights. For this deal to work, the River District also needs the agency’s board approval. That approval would seem to be a given because of the board’s commitment of $20 million to the purchase. But there are complications. 

    Not so simple

    You are likely not shocked that Front Range water providers have not been thrilled with this pending transfer. In June, they asked the CWCB to hold a hearing to express their concerns.

    At a September 19th meeting held on the campus of Fort Lewis College in Durango, the two primary parties testifying fell along predictable geographical lines: the Front Range (water providers) and the Western Slope (River District). CWCB staff also presented findings.

    The question before the CWCB was a simple one: Does the acquisition “preserve the natural environment to a reasonable degree?” If the answer is yes, the water right is suitable as an instream flow right. By law, the board must consider 11 factors when making this determination. These factors are found in the instream flow law’s implementing regulations and range from whether this transfer will cause injury to other water users, the impact on interstate water compacts, and the cost of the transaction.

    At the hearing, a host of messy realities surfaced. The first came after the CWCB staff presentation on the environmental importance of the 2.4-mile instream flow segment (i.e., whether the acquisition would in fact “preserve the natural environment to a reasonable degree”) in Glenwood Canyon.

    The Front Range and Western Slope parties then trumpeted the many but competing public benefits afforded by the Shoshone rights: rafting in Glenwood Canyon, orchard irrigation at Palisade, hospitals in Aurora.

    Public interest…in Colorado?

    Nearly all other Western states have incorporated some form of public interest requirement during water transfers. Although a difficult term to pin down, public interest reviews involve the consideration of public goods, such as healthy rivers or recreational amenities. The presiding bodies, when evaluating transactions, must weigh the private interests against the broader public benefits (or lack thereof).

    Colorado has no requirement. In 1995, the Colorado Supreme Court found the public interest theory conflicts with the prior appropriation doctrine. Without any legislative developments or a judicial about-face, that is that.

    So, if we don’t have a public interest review, why the parade of testimony?

    The most obvious answer is politics. When seeking approval (or denial) from an administrative body, it’s not a bad bet to show pretty pictures and tell compelling stories. But “politics” in this context can also be seen as a sub-in for those public interest principles.

    The eighth factor governing the CWCB’s deliberations requires consideration of the “effect of the proposed acquisition on the maximum utilization of the waters of the state.” Maximum utilization and the public interest, although not direct parallels, both share a principle of the “greatest good.”

    This backdoor introduction of the public interest gave listeners a glimpse of what the judicially disapproved principle might look like in Colorado water transfers.

    Whose right is it, anyway?

    That introduction at the hearing spurred perhaps the trickiest legal and policy issue of the day: Who has authority to enforce the instream flow agreement? That is, who can make the legal call instructing other water users to forgo their diversion so that the instream flow right gets its full water allocation. Is that a Western Slope political entity, the River District, or the statewide agency, the CWCB?

    And if it is the CWCB, does it have authority to grant its enforcement power to the River District? While the law appears to say yes, the River District can be granted authority, there is enough ambiguity in the 1973 law to perhaps send this to Colorado Supreme Court.

    The policy question, however, quickly returned parties to the realm of the public interest.

    The Front Range parties, arguably the most averse to any sniff of public interest requirements, ironically now found themselves supporting the idea that the broader public benefits should be under consideration.

    They contended that the CWCB should preserve its discretion to use and operate the instream-flow right. That, they said, would be sound public policy. Or if you will, “in the public interest.”

    Meanwhile, the River District, as the purchasing party and longstanding practitioners of Colorado water law, understandably wants to get what they are paying for: full control over exercising their water rights. Retaining enforcement powers under the agreement was, in fact, “the one sword that the West Slope” was prepared to fall on.

    Filings from both parties on Monday suggest that there is ongoing disagreement on this issue, meaning the CWCB will have a big decision to make.

    Can’t you just compromise?

    The next display of messiness came when it was time for the Board to apply the 11 factors.

    To those listening, it was quickly apparent that such a contested hearing had not been before these board members before. Few of the directors seemed to understand how each factor was to be applied to the proposal in front of them. Although no fault of the board members, the misalignment between their understanding of their roles and the consequences of the decision to be made felt almost incommensurate.

    That unpreparedness may have resulted in the Board’s parting directive to the parties to “compromise”: surely a favorable idea aimed at inspiring creative strategies and good faith negotiating.

    But in the adversarial world of Colorado water law, what might result from this directive?

    Such directives are common enough in water disputes. Recently, in the case of the Gross Reservoir expansion, a federal court, the 10th Circuit, told Denver Water and Save the Colorado to do the same.

    In matters of purely Colorado domain, however, such directives are normally reserved as an outcome of the water court process. Ordering it before litigation seemed premature, perhaps even subversive.

    The parties’ reactions were revealing here. The Front Range interests will certainly see it as a tally in their favor because it suggests the River District needs to move away from its hardline position. Perhaps their aversion to the public interest doctrine is not so set in stone, after all.

    For the River District, it is hard not to imagine some frustration. This was a contracted-for acquisition under Colorado’s longstanding, private property water rights regime. But here, too, the water is muddy. Recall that the CWCB is providing 20% of the purchase price. What kind of leverage, tacit or otherwise, does that commitment provide?

    Nov. 19th hearing

    These are all difficult questions, and they are being asked amidst a backdrop of high stakes, interstate Colorado River negotiations. Answering them will be no easy feat, and as the filings on Monday indicate, those questions remain unanswered. Whether it is indeed a “compromise” at the CWCB meeting on Wednesday, Nov. 19, or back to the drawing board for the River District is anyone’s guess. But the uncomfortable positions and contortions on display at the contested hearing gave an insightful glimpse into the messy realities of today and stress tests of the future for Colorado water law.

    November 12, 2025

    “If we take care of that water, we know that water is going to take care of us,” stated Lorelei Cloud, who has spent a lifetime advocating for water conservation and access. Cloud, a former vice chairman of the Southern Ute tribe, was also the first tribal member on record to serve on the Colorado Water Conservation Board.  On Thursday, Nov. 6, The Arts Campus at Willits (TACAW) hosted Cloud and a fellow trustee of The Nature Conservancy (TNC) Colorado, Johnny Le Coq, for a presentation on their respective backgrounds and water conservation work. The event, sponsored by Roaring Fork Conservancy and TNC, was a special installment of the Brooksher Watershed Institute. Lawyer Ramsey Kropf, who has decades of experience in representing Indian water rights cases in the Colorado and Klamath River basins, emceed.

    After some brief introductions, Cloud opened the evening by sharing the history of her people. The Roaring Fork Valley is part of ancestral Ute territories. Though the Utes, who referred to themselves as “Nuche,” or “the people,” and called their home the “Shining Mountains,” were seasonally nomadic before the arrival of colonial miners, Cloud shared that her people do not have a traditional migration story as some Indigenous peoples do. What the Nuche have is a creation story that ties them intrinsically to the soaring peaks and waterways of the Colorado Rocky Mountains.  Cloud explained that the seasonal nomadic moves of the Nuche were not considered to be migration but normal shifts, demonstrating respect and care for the ecosystems…

    “We believe that we are one and the same with nature,” Cloud said, elaborating that other species and even elements like water are akin to souls.

    November 12, 2025

    Utah and the six other Colorado River states reached a tentative agreement to continue working together on a plan to share the river’s water, but failed to secure a consensus plan ahead of an important Tuesday deadline. Utah, Arizona, California, Colorado, Nevada, New Mexico and Wyoming, all of which rely on the river for water, agreed to continue to meet until they have a “framework solution” by mid-February 2026, said Gene Shawcroft, chairman of the Colorado River Authority of Utah.

    “We were able to have enough of a framework put together that the federal government agrees with us that the framework can be continued to be refined in order for us to have a deal by the middle of February,” he told reporters in a negotiations update briefing on Wednesday…

    The basin states have had agreements in place on how Colorado River water has been allocated for over a century, and the post-2026 plan seeks to be the largest operational update since a 2007 plan to address how water is stored and pulled from Lake Powell and Lake Mead, the nation’s two largest reservoirs. Its users agree that prolonged drought and low reservoir conditions remain persistent challenges facing the river, but there’s still division on how to handle the discrepancy between water needs and what’s available in the system within one of the fastest-growing regions of the country. Lower Basin states have called for mandatory reductions during dry years. In a public letter to Interior Secretary Doug Burgum on Tuesday, Arizona Gov. Katie Hobbs and other Arizona leaders called it “alarming” that Upper Basin states, including Utah, “have repeatedly refused to implement any volume of binding, verifiable water supply reductions.”

    […]

    Upper Basin states don’t believe those types of cuts are necessary because they use less water than Lower Basin states, largely because of how water rights are allocated, favoring senior rights holders like California, Shawcroft said. These are the types of arguments still holding up a long-term deal.

    “The major sticking point is there’s a whole lot less water in the system than we anticipated, or there’s historically been,” he said. “The question is, how do you divide a pie that’s significantly smaller than it has been, when everyone’s used to getting that big piece of the pie?”

    November 12, 2025

    There’s still no plan for how the seven states that use water from the Colorado River will allocate the scarce resource after 2026. Tuesday, November 11, marked a deadline set by the federal government for the states to share a framework for new operating guidelines—another deadline that’s come and gone with no agreement. The river’s supply has drastically decreased since the original Colorado River Compactwas signed in 1922, due to climate change and overallocation of water. In 2007, the states agreed to interim operating guidelines, but those expire in 2026. Because Lake Powell and Lake Mead, the basin’s two biggest reservoirs, are federal projects managed by federal agencies, those agencies will need to do an environmental review and public comment period, as required by law. The federal government needs input from the states in a timely fashion to complete the review and public comment process, in order to have new rules in place by October 2026. On Tuesday night, the seven states, along with the Department of Interior and Bureau of Reclamation, issued a statement on the negotiations…

    “A supply-based proposal is the only way to move forward,” [Becky Mitchell] told attendees at the Colorado River District’s Across Divides conference on October 3. “We all have to be responding to supply.”

    That means that the new guidelines should be based on actual streamflows, rather than demand from water users.

    “We need to set aside building an operations plan that meets the needs as they are currently,” she said. “We need to let go of that dream and be able to figure out how to respond, and I think that’s been a bit of a struggle.”

    Water managers from the seven states that share the Colorado River have blown a deadline given to them by the federal government to come up with a rough plan on how the drought-stricken river will be shared in the future.

    The Upper Basin (Colorado, New Mexico, Utah and Wyoming) still cannot find agreement with the Lower Basin (California, Arizona and Nevada) about how the nation’s two largest reservoirs — Lake Powell and Lake Mead — will be operated and how cuts will be shared in dry years.

    In June, Scott Cameron, the U.S. Bureau of Reclamation’s acting assistant secretary for water and science, said federal officials would need to know the broad outlines of a plan from the states by Nov. 11. Despite frequent meetings in recent months, negotiators were unable to hammer out a deal by Tuesday, leaving future management for the water supply for 40 million people in the Southwest cloaked in uncertainty. 

    Instead, the states, the Interior Department and the federal Bureau of Reclamation released a short joint statement Tuesday afternoon, noting that serious and ongoing challenges face the Colorado River.

    “While more work needs to be done, collective progress has been made that warrants continued efforts to define and approve details for a finalized agreement,” the statement reads. “Through continued cooperation and coordinated action, there is a shared commitment to ensuring the long-term sustainability and resilience of the Colorado River system.”

    Environmental groups disappointed

    The failure to come up with a plan by the deadline has sparked criticism from the basin’s environmental groups. 

    “I’m really disappointed with how yesterday played out; the states did not have anything to meet the Nov. 11 deadline,” said John Berggren, a regional policy manager with Western Resource Advocates. “The fact that they didn’t have a basic framework for how to manage the system after 2026 is really unfortunate, and I think they missed a good chance to put forward something that we can all consider and examine as a basin.” 

    Representatives from the seven states have been in talks for two years about how to manage the river after the current guidelines expire. After a long standoff without much progress throughout 2024, state representatives in June offered a glimmer of hope for a way forward, floating a concept for sharing the river based on natural flows at Lee Ferry, the dividing line between the Upper and Lower basins, instead of water demand. But that hope evaporated like water off Lake Mead, with negotiators reportedly deadlocked again by the end of the summer.  

    A statement from environmental groups Great Basin Water Network and Living Rivers called the Nov. 11 deadline arbitrary and ineffectual, and said the inaction symbolizes the overall dysfunction on the river and in government. They chastised the states and federal government for the lack of transparency and lack of public participation surrounding negotiations.

    “The states don’t deserve the kid-glove treatment any longer,” Kyle Roerink, executive director of the Great Basin Water Network, said in a prepared statement. “They have a behavioral problem as much as they do a hydrology problem. Any entity that wants to increase use is unfit to manage our most precious resource.”

    A group of influential environmental organizations, including American Rivers, National Audubon Society, Environmental Defense Fund, The Nature Conservancy, Theodore Roosevelt Conservation Partnership, Trout Unlimited and Western Resource Advocates, released a joint statement Wednesday saying that they were deeply disappointed the states did not find consensus and that federal leadership will be essential. 

    The statement called for solutions that ground management decisions in the best available science, expand conservation programs, modernize infrastructure and ensure that Native American tribes — which have underutilized rights to a large share of the river’s water — play a meaningful role in shaping the river’s future.

    “We understand the extraordinary complexity of this challenge and the difficult tradeoffs the states are working hard to navigate — but the river isn’t going to wait for process or for politics,” the statement said. “Drought, intensified by increasingly extreme conditions, is reshaping the basin, and the window to secure the river’s future and move beyond crisis-driven policymaking is closing fast.”

    Since the turn of the century, the Colorado River basin has been locked in the grip of a megadrought. Climate change has robbed Western rivers of their flows, with the basin seeing a 20% decline from the 20th century average, according to scientists. Those factors, as well as unrelenting water demands, have pushed Lake Powell and Lake Mead to record-low levels in recent years and thrown river management into crisis mode. 

    The current negotiations between the seven states are aimed at replacing the 2007 Interim Guidelines, which lay out how the reservoirs will be operated and shortages shared, and which expire at the end of 2026. New guidelines would need to be in place by the beginning of the next water year, Oct. 1, 2026, leaving little time to complete the required National Environmental Policy Act (NEPA) review process.

    The 2007 guidelines set annual Powell and Mead releases based on reservoir levels and do not go far enough to prevent them from being drawn down during consecutive dry years. In 2022, Lake Powell flirted with falling below a critical elevation to make hydropower, and may be headed there again next year if conditions don’t improve.

    Sticking points

    Over the past few months, the positions of two of the states — Colorado and Arizona — have emerged as one of the main sources of disagreement. Water from the Colorado River has fueled the exponential growth in recent decades of Arizona’s cities, which are the economic and political powerhouse of the state, along with some of the most productive farmland in the basin. But Arizona’s reliance on the junior water rights of the Central Arizona Project means it is first on the chopping block for cuts. 

    Arizona representatives have said that the deepest cuts should be shared basinwide, including by the Upper Basin. Gov. Katie Hobbs and other state lawmakers said in a Nov. 11 letter to Interior Secretary Doug Burgum that Arizona’s Colorado River allocation is important to the nation’s growth and independence and that Colorado River reliability is a matter of national security. The letter highlighted how the state plays a critical role in manufacturing semiconductors and information-technology products. 

    “With such high stakes for Arizona and the nation, we find it alarming that the Upper Basin states have repeatedly refused to implement any volume of binding, verifiable water supply reductions,” the letter reads. “This extreme negotiating posture — four of the seven basin states refusing to participate in any sharing of water shortages — has led to a fundamental impasse that is preventing the successful development of a seven-state consensus plan for the management of the Colorado River.”

    The Lower Basin has committed to a 1.5 million acre-foot reduction, which accounts for evaporation and transit losses.

    Water managers from Colorado — which is the de facto leader of the Upper Basin with a 51.75% share of the water allocated to the four Upper Basin states — have pushed back on the notion that their states should contribute to cutbacks in water use since their water users already suffer shortages in dry years and the four states have never used their entire allocation of the river, while the Lower Basin overuses its share. Colorado representative Becky Mitchell has repeatedly said that any cuts the state makes must be voluntary, not mandatory.

    However, the Upper Basin states have been experimenting for years with conservation programs that pay water users to cut back, most recently in 2023 and 2024 with the federally funded System Conservation Pilot Program. In a proposal submitted in March 2024, the Upper Basin states offered up a potential conservation pool in Lake Powell of up to 200,000 acre-feet a year, and most water users accept that some type of future conservation program for the Upper Basin is inevitable

    What happens now?

    Federal officials had previously set a second deadline of Feb. 14, 2026, for the states to present details of a plan. They have repeatedly said that if the seven states fail to come up with an agreement, Reclamation will exercise its authority to protect critical reservoir levels. That could include releases from upstream reservoirs to prop up Powell and Mead, including releasing water from Colorado’s Blue Mesa Reservoir on the Gunnison River. 

    Reclamation is moving forward with its NEPA process and said in early October that it plans to have a draft environmental impact statement by the end of the year. Representatives from the bureau were not available for comment Wednesday due to the government shutdown. Cameron has said that the alternatives analyzed in the EIS will be broad enough that they would capture any seven-state agreement, which they could then plug in as the preferred alternative — assuming the states come up with something.

    “The basin states remain committed to collaboration grounded in the best available science and respect for all Colorado River water users,” Mitchell said in a prepared statement. “We are taking a meaningful step toward long-term sustainability and demonstrating a shared determination to find supply-driven solutions.”

    November 11, 2025

    Utah and six other states along the Colorado River blew past their deadline Tuesday to reach a new deal on managing the dwindling river, but negotiations aren’t over. 

    “We will continue to engage with our partners across the Basin to develop a framework that protects water users and the system as a whole,” Utah Gov. Spencer Cox said Tuesday afternoon on the social media site X. 

    The river contributes 27% of Utah’s water supply, and provides water to 40 million people across the U.S. and Mexico. Drought, overuse and hotter temperatures tied to climate change have all combined to shrink its flow. 

    The federal government had said it would step in and make its own plan if states failed to reach broad consensus by Tuesday, but the states agree they don’t want that to happen, Cox said.

    “While the Basin States did not finalize an agreement today on post-2026 Colorado River operations, our commitment to a state-led path remains,” the governor said. 

    The U.S. Department of the Interior did not respond to questions from Utah News Dispatch Tuesday evening about the timeline and whether it would intervene. The current agreement runs through late 2026. 

    The federal agency and Utah’s negotiator Gene Shawcroft issued the same prepared statement, saying the talks yielded “collective progress.” They did not give any details on sticking points. 

    The seven states, the Department of the Interior and the U.S. Bureau of Reclamation, which manages water in the West, all “recognize the serious and ongoing challenges facing the Colorado River,” their statement says. “Prolonged drought and low reservoir conditions have placed extraordinary pressure on this critical water resource that supports 40 million people, tribal nations, agriculture, and industry.” 

    They said the states and federal agencies share a commitment to ensuring the river’s long-term sustainability. 

    “While more work needs to be done, collective progress has been made that warrants continued efforts to define and approve details for a finalized agreement,” the statement says. 

    The four Upper Basin states — Utah, Colorado, New Mexico and Wyoming — and the Lower Basin states of Nevada, Arizona and California presented competing plans to the federal government last year. 

    The Upper Basin states have sought to fend off mandatory cuts in dry years, saying they generally use much less than they’re allocated. The Lower Basin states have insisted that all seven absorb cuts in dry years. 

    In part to prepare for the possibility of mandatory cuts, Utah has been investing in measuring and monitoring water use in recent years. 

    In 2023, the Legislature set aside $1 million for a Colorado River measurement infrastructure project and $650,000 in ongoing yearly funding, according to the Utah Division of Water Rights.

    Metropolitan General Manager Deven Upadhyay issues the following statement regarding the seven Colorado River Basin states continued efforts to reach consensus on post-2026 rules governing operation of the Colorado River: 

    “The only path to developing a sustainable Colorado River is through collaboration and consensus. We are grateful that the seven states that rely on the river remain at the table, along with the federal Department of Interior, but more work needs to be done, and quickly.

    “The work ahead will require every state and water user to look beyond just their own needs and work toward the greater good of the Southwest. If reductions in water use are shared equitably across the Basin, no one state or sector will bear the burden alone.

    “Metropolitan remains committed to forging such a consensus, and we look forward to the opportunity to participate in the ongoing discussions in a meaningful way. An agreement that includes tools allowing for smart water management, like flexible storage in Lake Mead and opportunities for shared investments across states, will minimize the pain of living with the new, lower flows of the Colorado River. If we focus on building solutions – rather than legal arguments – we can develop new guidelines that allow water users to have access to the water they need, when they need it most.”

    “Metropolitan is preparing to live with less imported water in urban Southern California, building on decades of lower water use. But we cannot solve the problem alone. We cannot lose our access to the Colorado River entirely. Our region – home to half of the people and half of the economic activity in the Basin – relies on the river. And we are committed to its success.”
