Tribal leaders are pushing for a seat at the negotiating table, where allocation and management of the Colorado River will be determined. The representatives from tribal nations joined a panel discussion called “Colorado River: The Emerging Role of Tribes in the 2026 Negotiations,” moderated by the Nature Conservancy’s Western Colorado Water Project Director Celene Hawkins, at the Colorado Water Congress in Steamboat Springs. During the panel, water executives from several of the 30 tribes relying on the Colorado River Basin’s water talked about their challenges and successes in managing the precious resource. While Native American Tribes hold significant water rights in the Colorado River Basin, their role in the system’s management is limited. Key hurdles, they said, include funding to implement water programs, infrastructure improvements, and water accountability…

“In the past, tribes have been treated as an afterthought when it comes to water issues and negotiations,” said Lisa Yellow Eagle. “But now we’re having open, honest dialogue.”

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

The latest projections for the Colorado River are out, and they paint a picture of more dry conditions and dropping reservoirs.

The river supplies water to nearly 40 million people across the Southwest, and it’s stretched thin by climate change and steady demand. New data from the Bureau of Reclamation shows low inflows and dropping water levels at the nation’s two largest reservoirs – Lake Powell and Lake Mead. This is just the latest bad news in the midst of a megadrought going back more than two decades.

The river will enter 2026 in a “Tier 1 Shortage,” under which Arizona and Nevada will face mandatory cutbacks to their water supply. While they put some water users in an uncomfortable pinch, those cutbacks aren’t raising the same alarm bells they once did. Dry conditions and water reductions have become a sort of new normal. Shortage conditions for the lower Colorado River basin were first declared in 2021, and have been in place since.

On the ground, the agencies that have to deal with these cutbacks seem to be adapting. Major water users tout their conservation efforts. The towns and cities that are most likely to face permanent reductions to their water use are putting hundreds of millions of dollars into systems that will steel them against smaller water deliveries in the future.

Meanwhile, further upstream, dropping levels at Lake Powell are creating a near-term crisis. The new federal water data shows the reservoir ending this year only 27% full. If it drops much lower, the reservoir could fall below the pipes which allow water to flow through hydropower generators inside the dam – jeopardizing electricity generation for about five million people across seven states. The new data shows that could happen as soon as November 2026.

Policymakers who can shape the region’s long-term response to dry conditions have been facing mounting calls for action. They are under pressure to come up with new rules for managing the river in the long-term before the current guidelines expire in 2026.

Cynthia Campbell, who directs a water policy research center at Arizona State University, said instead of urgently working on a long-term plan, those policymakers seem to have spent the past few years “gambling” on the idea that water might come back and reverse the crisis at major reservoirs.

“If they were betting on that,” she said, “Then they’re losing, because it is continuing to march on. Mother Nature is continuing to march on, and we’re continuing to see declines in the system.”

While some small glimmers of hope have emerged from negotiations, water managers from the seven states that use the Colorado River seem stuck at an impasse.

“We have yet to see any courage in the sense of making choices that will bolster long-term system reliability,” said Campbell, who formerly served as a top water lawyer for the city of Phoenix. “There seems to be an unwillingness on the collected parties to do that, and that is not good news.”

Climate scientists say the river’s dry conditions are unlikely to turn around anytime soon. A warming, drying climate is sapping the region of its water at every turn, and significant reductions to demand are likely the only solution to that new reality.

June 27, 2025

Deadlocked for months in tense, closed-door meetings, Colorado River states may be one step closer to an agreement. Representatives from each of the seven Western states have agreed to discuss a new path forward — one that could more firmly ground Colorado River policy in hydrological reality as snowpack fails to deliver, reservoirs decline and fears mount…The proposal, presented for the first time publicly at a meeting in Arizona on June 17, would base the release of water from Lake Powell on a three-year average of the “natural flows” of the river. Water released from Lake Powell ends up in Lake Mead, the source of roughly 90 percent of Southern Nevada’s supply…The natural-flow proposal, while details remain sparse, would be a stunning departure from guidelines minted in 2007, which some argue don’t take into account declining water availability.

I’m a little slow getting to this one, thanks mostly to being consumed by the whole public land sale brouhaha, but better late than never.

After years of bickering, wrangling, fighting, and digging in their heels, representatives of the seven Colorado River Basin states may have finally agreed on a “revolutionary” way to split up the river’s waters: They’re going to base it on how much water is actually in the river at any given time.

So, apparently, in this world, “revolutionary” is a synonym for the most common sense, obvious, and, really, necessary way to do things.

More specifically, the Upper Basin would release a percentage of the rolling three-year average of the“natural flow”* at Lee Ferry from Glen Canyon Dam, making it available to the Lower Basin. That’s opposed to the current model, where the Upper Basin is required to release at least 75 million acre-feet every ten years (or 7.5 MAF per year on average)**

Let’s pause for a moment and use an analogy to reflect on how short-sighted and dumb that original approach was. [ed. emphasis mine] Say someone has a potato farm and they die, leaving the farm to their two children, Upper and Lower, who must determine how to divide the farm and its yield between them. They look back at their parent’s ledgers, and determine that the farm has produced at least 15 tons of potatoes annually during the previous few years.

So they agree to divide it in half, with 7.5 tons going to each of them each year. But Upper will actually live on the farm, and has the keys to the lock on the gate, so they add into their Potato Farm Compact a clause that requires Upper to not prevent Lower from taking 75 tons of potatoes from the farm during every 10 year period.

This works out fine as long as the farm produces 15 tons per year. But what happens if you signed the Compact during an abnormally productive period, and the long-term average yield was far lower than 15 tons? Or what happens as the soil becomes less fertile and the irrigation water becomes more scarce and production drops far below 15 tons per year? Under the agreement, Upper still has to allow Lower to take 7.5 tons annually, leaving Upper with far less, maybe even nothing during a string of bad years.
Obviously, this is untenable. And, just as obviously, it would have made far more sense for Upper and Lower to simply divide each year’s harvest in half and each take 50% of whatever the total might be. Just as obviously, that would have been the smartest way to divide up the Colorado River in the first place.
Of course, a river is not a potato crop.

To determine how much potatoes you have, you just put them on a scale. Determining the “natural flow” of the Colorado River is far more difficult, and requires inputting:

• data from 29 upstream streamflow gauges/gages;
• historic outflow and pool elevations from 12 main-stem and 12 off-stream reservoirs;
• upstream consumptive uses and losses.

While that doesn’t sound so complicated, gathering all of these inputs — reservoir evaporation, for example, or the exact amount consumed by agriculture — can require separate calculations and guesswork of their own.

But the states wouldn’t be coming up with this from scratch. The Bureau of Reclamation already calculates the river’s natural flow at Lees Ferry along with Lake Powell’s unregulated inflow. As you can see from the graph below, the river has not consistently delivered 15 million acre-feet per year, forcing the Upper Basin to deplete their savings account (Lake Powell) in order to meet its Colorado River Compact obligations.

If the supply driven concept is implemented, it will base Glen Canyon Dam releases on a fixed percentage of the previous three-year moving average. For example, the average of water years 2022, 2023, and 2024 was 13 million acre-feet. If the Upper Basin and Lower Basin were to each take 50%, then the Glen Canyon release this year would be 6.5 million acre-feet (plus something for Mexico, presumably, although this isn’t clear. I highly doubt the Lower Basin will settle for just 50%, given that it has far more people, more agriculture, and is just thirstier, overall, but let’s go with that figure since it’s what’s in the Colorado River Compact, sort of.

That would actually work: The Lower Basin states’ consumptive use last calendar year was about 5.8 million acre-feet, so they’d have enough to use, and a little on top for evaporation from reservoirs (which is not included in the Lower Basin’s accounting). It would leave the Upper Basin enough for consumption and some extra for reservoir storage. 

But if you go with the previous three years (‘20,’21,’22), you end up with an average of just 9 million acre-feet, 50% of which would be a measly 4.5 million acre-feet, forcing downstream users — namely the Central Arizona Project, since their rights are junior to California’s — to take deep cuts. And it would leave the Upper Basin just enough to meet their needs, meaning they’d have to draw down Lake Powell or other reservoirs to fulfill their obligations. 

Another tricky scenario would be if three decent water years were followed by an extremely dry year. Releases from Lake Powell could significantly exceed inflows, which might deplete the reservoir enough to bring it down to minimum power pool, which is no bueno. 

While this may be the closest the states have come to reaching some sort of consensus on how to run the River beyond 2026, it seems as if there is still many sticky details to work out. How are they going to agree on a fixed percentage? What will the minimum release be? And how will that fly with the Upper Basin during years such as 2002, when the natural flow at Lees Ferry was a mere 5.8 million acre-feet? Time’s running out. 

Now for some more data for your pondering pleasure:

This passage, from David Starr Jordan’s Fish Commission Bulletin 1889: Report of Explorations in Colorado and Utah During the Summer of 1889, remains relevant today:

Uggh. Fire season is getting ugly. The Dragon Bravo Fire blew up and burned the historic Grand Canyon Lodge on the North Rim. The Deer Creek Fire, burning near Old La Sal, Utah, just west of the Colorado state line, has grown to almost 12,000 acres and exhibited some erratic behavior (see video above). Just northeast of there, the Wright Draw and Turner Gulch fires have forced the closure of Hwy. 141 and numerous evacuations in the Unaweep Canyon area outside Gateway (the community of Gateway is not yet threatened). The South Rim Fire at the Black Canyon of the Gunnison is now at 4,000 acres. The Laguna Fire west of Abiquiu Reservoir in New Mexico has reached 15,200 acres. And the air in the West is basically full of smoke. 

Here’s hoping for rain and lots of it, sans lightning, please.

Becky Mitchell and Doug Kenney had much to say at Crested Butte. Just as important may have been what they did not say.

The apple cart of the Colorado River has been upset for 25 years, and Doug Kenney and Becky Michell were on stage June 24 at the Crested Butte Public Policy Forum to talk about the bruised apples.

There’s broad understanding that what worked in the past won’t work in the future. As to what will work — ah, well, that has yet to be resolved. “So far, we haven’t really been able to pull the demands down as quickly as supplies have been going down,” said Mitchell.

Adding tension to the conversation is another so-so or worse spring runoff in the river. Despite a decent snow year in northern Colorado, yet another early, warm and mostly drier-than-usual spring has produced an anemic projected runoff of a little over 9 million acre-feet. Average runoff into Lake Powell has been 12 million in recent years. The compact governing the river between the three lower-basin states and the four upper basin states assumed at least 20.

Kenney directs the Western Water Policy Program at the University of Colorado Boulder’s Getches-Wilkinson Center. The program puts on a conference each June that is considered one of several must-attend events for those drawn to the unceasing drama about Colorado’s namesake river.

The river and its tributaries provide water for farms almost to Kansas and Nebraska and, on the west side, to 23 million people crowded along the Pacific Ocean in southern California.

In Crested Butte, Kenney said that unlike other people in Colorado River discussions, whether they represent environmental or agriculture organizations, he enjoys a rare freedom. “I tell people sometimes, I don’t have a dog in the fight, and by that, I just mean I don’t have to represent an interest.”

Then he added: “That’s not entirely true.” He went on to confess that when he sees the Colorado River “sometimes it gives me goosebumps. And I’m not a goosebumps sort of guy.”

Mitchell shared that she was a “solid B student” who had grown up in Hawaii before arriving in Colorado to pick up two degrees at the Colorado School of Mines. She worked primarily as a consulting engineer before becoming the director of the Colorado Water Conservation Board. In 2024, Gov. Jared Polis named her to a new position in Colorado government: the state’s negotiator on Colorado River issues.  Unlike others in such roles, she’s not a lawyer.

“Often I think of everything as a math problem,” she said. “And a lot of what you see with the Colorado River is a math problem. It’s kind of simple math, almost like just addition and subtraction, not even algebra or multiplication.”

The two provided a high-level, yet sometimes detailed overview of the Colorado River during their hour on stage. However, students of the Colorado River, especially about the dramas, might have wanted another hour and the opportunity to ask additional questions.

For example, what do they make of the so-called “natural flow proposal” that was first formally discussed at a public meeting earlier that day in Arizona. As reported by the Las Vegas Review-Journal, this would base the release of water from Lake Powell on a three-year average of the “natural flows” of the river.

In their comments at Crested Butte, Mitchell and Kenney both broadly identified the need for the river to be shared in ways aligned with what Mother Nature is delivering, not a century-old compact.

Later, at a different meeting, Mitchell had this to say: “What we know today is that for any approach to work, it must be supply driven, perform well under both dry and varying hydrologies, and adapt to uncertain future conditions fundamental to this ‘divorce,’ or how we call it in Colorado, the conscious uncoupling.’”

Others might have asked Mitchell about the tensions behind the closed-door sessions — and the things that Kenney mentioned she could not really talk about in a public forum.

Or about the amount of water used to grow hay, including alfalfa, and other fodder crops for livestock. A 2020 study published in Nature Sustainability found that 55% of the water in the Colorado River Basin altogether goes to crops to feed primarily cattle. In the upper basin, it’s much higher.

Mitchell and Kenney did talk about Mead and Powell, the two big reservoirs in the basin, as all Colorado River conversations must.

“Those are the two biggest reservoirs in the United States, and they happen to fall on a river that’s not even one of the top 20 biggest rivers in the U.S. in terms of volume,” observed Kenney. The reservoirs were close to full 25 years ago. Now, they’re two thirds empty. “Optimists would say one-third full,” he said.

If you have more water going out than you have coming in, he explained, you have a mass balance problem. “That’s happening 8 out of 10 years. More water leaves than is coming into the reservoirs under guidelines adopted in 2007. Those interim guidelines govern operations, including how much water is released from the reservoirs and when.

“When we talk about Big River issues right now, the Big River issue is getting the system into balance and bringing back the sustainability of the system,” Kenney explained.

Management of the reservoirs was premised on meeting demand. To be more precise, demands of the lower-basin states. Until relatively recently, the lower-basin states were taking an average 10 million acre-feet even if the river delivered only 5 to 10 million acre-feet for the entire basin. Having two big reservoirs upstream allowed them to ignore the winters of scant snow in the headwaters and the rising spring temperatures that spiked evaporation and transpiration.

The first big shock was in 2002, when the river delivered only 3.8 million acre-feet. That was bad, very bad. But the reservoirs still had a lot of water. And there had been bad snow years before. In 1934, for example, the river delivered only 3.9 million acre-feet. And in 1977, a cold but uncommonly snowless winter, it had delivered 4.8 million acre-feet.

A big snow year did not soon follow 2002, so the states, guided by the Bureau of Reclamation, came up with a sort-of short-term set of solutions called the 2007 Interim Guidelines. Those guidelines remain in effect but are to be replaced with new guidelines. That’s a way of saying how the river is to be managed and, more precisely, who gets what and when. They’re called the post-2026 guidelines.

As were the 2007 guidelines, these will be interim, because the hydrology of the Colorado River Basin is not static. It is changing, with some concern that the river, already slimmed down from its 20th century average, will continue to shrink. The Colorado River Compact that was devised in 1922 to apportion the river’s waters assumed somewhere around 20 million acre-feet. This century the average has been 12.5 million acre-feet.

“The math problem is becoming worse,” said Kenney.

It will likely worsen. Some scientists have projected a further decline in decades ahead, conceivably to an average 10 million acre-feet or less.

How to shrink demands to correspond with the shrinking river?

Mitchell offered some thin optimism. Demands have ceased to rise. They have actually declined. The lower-basin states have reduced their take from the river to 7.5 million acre-feet.

That’s what the compact apportioned. But again, the compact from 1922 was flawed. It assumed more water than the river has delivered. Because of the two big reservoirs in the deserts of Utah and Arizona, the lower-basin states have been able to get their 7.5 million acre-feet (and more, until relatively recently). Arizona and California take way more than half of the river’s harvest. And because the upper-basin states were not taking their full allocation, they could get away with it without causing harm.

The 21st century combined with the aridification caused by rising temperatures have forced the issue. Even so, the reckoning has come slowly. The lower basin states did not reduce demand to stay within the compact until forced to by a declared shortage in August 2021.

While the decision was not a surprise to veteran Colorado River watchers, it vaulted the Colorado River troubles high into the national consciousness. The story ran on the front page of the New York Times: “In a First, U.S. Declares Shortage on the Colorado River, Forcing Water Cuts.” Arizona farms took the brunt of this declaration, but as the Times noted, wider reductions loomed as climate change continues to affect flows into the river.

The upper-basin states have been averaging 4.4 to 4.5 million acre-feet, far less than the 7.5 million acre-feet apportionment in the compact. How much they take depends upon how much it snows and rains.

“We have highs and lows because of hydrology. That can shift a lot. A really good example is from 2021 to 2022. Our use was 4.9 (million acre-feet), and then it went down to 3.9 the following year. That wasn’t because we’re amazing people.”

It was, Mitchell explained at Crested Butte, as she does in all of her talks, because the upper basin is limited by what Mother Nature actually delivers. The upper basin has no big dams upstream to serve as an aqua bank account. It has to moderate demand based on what kind of snow — and rain — year occurs.

When there’s insufficient water, the state engineer in Colorado and his district engineers cut off water users, mostly ranchers irrigating grasses.

The compact struck among the four-upper basin states in 1948 used a more common-sense approach for how to allocate the 7.5 million acre-feet in the 1922 compact. It allocated the water among the four states based on proportions. Colorado gets a little more than half — and uses most of it. Wyoming has never come close to developing its share. Regardless, the rule of percentages makes sense for an uncertain hydrology.

“We realized real quickly that Mother Nature reigned supreme,” said Mitchell. I would be in big trouble if I said the lower basin should do the same. I think they should, but they’re not there yet.”

Mitchell used an analogy to describe the difficult transition for the lower basin. It is much harder to take candy from a baby after they have it,” she said.

“It’s going to be hard for them, and my heart goes out to them. But we have an example up here of how it works. Seniors work with juniors,” she explained, using the shorthand for senior and junior water uses under the prior appropriation system governing water use in Colorado and most Western states. Ag works with environment interests, utilities with agriculture, and so on. They cut deals in advance of water-short years.

“We have examples of how to make it work. You have a budget. You have to work within it. That’s the deal. And sometimes that budget might fluctuate.”

“We’ve not lost all of our junior water-right holders in Colorado because of one bad year or two bad years or three bad years, in a row, because we figure out how to make it work. And what we are saying to the lower basin is figure out where the deals are to be made.

And she drew upon her childhood for another dynamic.

“What my mom always said is, you can have anything you want, but you can’t have everything you want.”

Translated to the lower basins, that means “you can’t have chip factories and the largest agriculture in the world and golf courses and pools and Scottsdale and whatever.  You can have the capability to have a strong economy, a sustainable system. You just can’t have it all.”

The federal government, through the Bureau of Reclamation, an agency housed within the Department of Interior, built the dams. Reclamation manages the dams. As Mitchell said, they turn the spigots. The onus is on the states to create a solution, an agreement of how to share the shrinking river, but the federal government could step in, if forced to. Mitchell said the feds don’t want to.

“They really want a consensus deal with the seven states,” she said. That’s a hard thing, because there’s no way to do this without change. The math is the math. The facts are the facts. There’s not the 50 million acre-feet in these reservoirs that there were when these (2007) guidelines started. And so the consensus is harder.”

Mitchell said she wouldn’t disparage those who created the now obviously flawed 2007 guidelines. Climatologists had suggested only a 3% probability of the runoff that has happened since then would come to pass.

“What we’re trying to create through this federal process is something that can handle all the hydrologies. How do we all suffer when the river is suffering? How do we all benefit when the river is flush? And what does benefit look like? That’s different in the upper basin than in the lower basin.”

The federal government in this case has been nudging the states toward agreement.

“They’re trying to say, ‘You know, you might be able to open up different project funding if you guys can get to a deal.’ We know we need a deal. I’m not going to promise you that we’re going to get there, but it is a goal. And (the federal agencies) are part of that goal. They don’t want to make the hard decisions of cutting people off. They are the water masters in the lower basin. They can turn the valves, and that’s their role.”

Added Kenney: “Typically the states are happiest when the federal government is silent, (but) sometimes it’s helpful to have a federal government that is throwing out some ultimatums and some deadlines and some threats.”

In the last six months, the federal involvement in the negotiations has grown, and it might grow yet. But a big part of the process — as Mitchell had said — is that the states need to be coming up with their wish list for Congress for consideration next spring.

“So there is a federal role,” Kenney summarized. “It evolves based on how the states are doing. But the tradition is you want the feds to stay away until it’s time for someone to write the check.”

MItchell had the last word. She again pointed to the meager runoff from this year’s upper-basin rivers, source of 92% of the river’s water. Runoff is projected at a little more than 5 million acre-feet into Powell, which is to release 7.48 million acre-feet to the lower basin.

Again, it’s a match problem. And it could get worse.

“If next year looks anything like this year, or even as a 12 million acre-foot river, actions absolutely have to be taken., and those actions are going to be greater than anybody has put on the table voluntary.”

This story is part of ongoing coverage of the Colorado River, produced by KUNC and supported by the Walton Family Foundation.

There’s a break in the clouds that have hovered over Colorado River negotiations for more than a year. State water leaders appear to be coalescing behind a new proposal for sharing the river after talks were stuck in a deadlock for more than a year.

The river is used by nearly 40 million people across seven states and Mexico, but it’s shrinking due to climate change. As a result, state leaders need to rein in demand. For months, they were mired in a standoff about how to interpret a century-old legal agreement. The new proposal is completely different.

Instead of those states leaning on old rules that don’t account for climate change, they’re proposing a new system that divides the river based on how much water is in it today.

“We finally have an approach that at least allows a glimmer of hope that the laying down of arms is possible,” said John Fleck, a writer and water policy researcher at the University of New Mexico.

The long, tense negotiations have mostly been stuck on one issue: How much water should the Upper Basin states — Colorado, Utah, Wyoming, and New Mexico — send downstream from their largest reservoir, Lake Powell? 

The new plan says the amount should be based on a three-year rolling average of the “natural flows” in the river — basically, how much water would flow through it if human dams and diversion weren’t in the way.

States would still have to negotiate the exact percentage of those “natural flows” that would go downstream to the Lower Basin states of California, Arizona and Nevada. Picking that number will likely be difficult, but the fact that states are willing to base it on current climate conditions represents a major philosophical shift in how the river is divided.

“This new approach gets beyond the obsessively arcane discussions about various interpretations of laws written 100 years ago, with people hoping that their lawyers’ arguments can mean they get more water,” Fleck said. “It says, ‘Look, we all have to share this river. We have to do some math about how much water it really has.’”

Details of the plan first emerged in a meeting of the Arizona Reconsultation Committee, where the state’s water leaders gather to discuss Arizona’s position in multistate talks. Tom Buschatzke, director of the Arizona Department of Water Resources, described the plan as “innovative.”

“I was very pessimistic that we were on a path towards litigation,” he said. “I’m more optimistic now that we can avoid that path if we can make this work.”

Buschatzke emphasized that the proposal is in its early stages. The concept is now heading to the Bureau of Reclamation, the federal water agency which manages dams and reservoirs in the West. Employees there will run models to figure out exactly how much water would flow between the two basins.

State and federal leaders are in a crunch to finalize new water sharing rules before a 2026 deadline, when the current rules expire.

“It is still just a concept,” Buschatzke said. “We haven’t agreed to anything at this point, but we agreed to test it.”

Colorado, which often speaks on behalf of all four Upper Basin states, appears cautiously supportive of the plan.

“Colorado remains committed to developing supply-driven, sustainable operations of Lake Powell and Lake Mead,” Becky Mitchell, Colorado’s top water negotiator, wrote to KUNC in a statement. “The natural flow approach is one way to achieve this, if it is done right.”

Colorado and its allies initially dug in their heels on a very specific interpretation of the 1922 Colorado River compact, arguing that they shouldn’t have to take new cutbacks to their water supplies since they feel the impacts of climate change-fueled shortages more than their downstream neighbors.

“There is no doubt that Arizona views things differently than the Upper Division States, and a successful framework will set aside our differing views and focus instead on the health and sustainability of the Colorado River System for all who depend upon it,” Mitchell wrote.

June 18, 2025

Key Points

• Arizona officials present details of a new proposal to share future shortages on the Colorado River.
• The “supply-driven” solution would base allocations on the river’s actual flows, not on storage in the reservoirs.
• Upper Basin states say the plan has problems, but Gov. Katie Hobbs insisted Arizona will defend its river allocation and demand other states take cuts.

Negotiators for the seven states arguing over diminished Colorado River water are discussing an option they hope will end their deadlock, one that Arizona officials say would focus less on who gets what and more on what the river can realistically provide. They’re calling it the “supply-driven” solution, Arizona Water Resources Director Tom Buschatzke said, and it links the required water deliveries out of Glen Canyon Dam to what might naturally be flowing downstream at Lees Ferry if the dam weren’t there. The Rocky Mountain states upstream from there would have to let that amount pass, and the Southwestern states would have to live within its limits. It’s intended as a fair way of adapting — and shrinking — the region’s use of a river whose flow was once thought to exceed 15 million acre-feet of water a year but, in the last 25 years, has averaged 12.4 million…

A Colorado State University climate scientist recently projected that the region’s warming trajectory could drop the flow to 10 million by the end of this century — a plunge of about a third of the water that the first state negotiators agreed to divvy up with the 1922 Colorado River Compact…

So far, agreement about what’s fair has appeared distant. The Lower Basin states of Arizona, California and Nevada have the bulk of the region’s population and farm production, and have fully developed and then started to cut back on the half of the river’s flow that the compact awarded them. The Upper Basin states of Colorado, New Mexico, Utah and Wyoming have not fully developed their share of the water — a share that no longer fully exists. They have balked at cutting their existing uses to meet the compact’s requirement that they send at least half of the river’s flow of a century ago now that a changing climate has exposed the folly of the compact’s numbers. The supply-driven model would generally mandate a flow past Lees Ferry to the Southwestern states equal to a rolling three-year average of the natural flow that the mountain snowmelt provides, Buschatzke said. There would be upper and lower bounds on that number, to account for needs such as protecting reservoir levels that are safe for Glen Canyon and Hoover dam operations. Those bounds are as yet unidentified.

Key Points (AI assisted summary)

• After months of little progress and public battles, negotiators from the seven Colorado River states may have regained their footing toward a shortage-sharing agreement.
• Officials say the Trump administration has engaged in the work to complete an agreement, spurring the states to resume talks. Without a deal, the federal government would impose its own plan.
• An official said a new agreement could require changes in the bedrock laws that govern the river, suggesting that even the “Law of the River,” a 100-year old management framework, could face scrutiny.

Metaphors about divorce and grief defined an emotional presentation about the Colorado River in Boulder, Colorado, on June 6. Those metaphors, however, did not represent strife or disaster in stalled water negotiations, but apparent progress and the willingness to let go of past ideas and move toward compromise.

“We’ve heard about the stages of grief … about denial and anger and the need to be at bargaining,” said Chuck Cullom, executive director of the Upper Colorado River Commission. “Well, I believe the basin states are there.”

Officials involved in tense negotiations over how to manage shortages on the Colorado River suggested that months of harsh talk and stalemates have ended and negotiators are exploring new options…Federal officials indicated that even parts of the “Law of the River,” a 100-year-old legal framework that governs Colorado River allocations, could change as a result of the negotiations.

“We’re trying to pivot to something else and be creative, and we have good engagement on that right now,” said Colby Pellegrino, deputy general manager of the Southern Nevada Water Authority…While most of the negotiators from the seven Colorado River basin states did not attend the conference at the University of Colorado in Boulder, the speakers who did attend were cautiously optimistic about their chances at making a deal.

In his much-anticipated keynote speech at the conclusion of this year’s Water Resources Research Center’s Annual Conference at the University of Arizona, ADWR Director Tom Buschatzke laid out the vast complexities of managing the Colorado River system.

With a deep sigh, he acknowledged that managing the vital river system “is a huge burden” for those mere mortals charged with that task.

The Director included in his presentation to the conference audience an image he often uses when describing the on-going negotiations over new guidelines for river management: a depiction of the mythical Greek god Atlas holding up the world.

Buschatzke told the WRRC attendees that “one thing that Atlas had going for him that we don’t have is that Atlas was a god, and we are not gods, so it is a huge burden for us to try to deal with this river.”

Divided into Upper and Lower Basins, comprised of seven U.S. states, the Colorado River system is operated by the Bureau of Reclamation under the terms of agreements that are scheduled to run out at the end of 2026. For well over a year, representatives of those seven states have been locked into often-intense negotiations over what the new operating guidelines should look like. Director Buschatzke is Arizona’s representative to those negotiations.

The Director described Lower Basin conservation efforts in recent years. Among those efforts, the Lower Basin and the Republic of Mexico having combined to reduce consumptive use of river water by 20 percent since 2000. He also noted that Lower Basin states and Mexico have left enough water in Lake Mead, especially since 2014, to raise surface levels by more than 100 feet.

“Without this, we’d be in a heap of trouble,” he said. “We’ve shown that we can take proactive measures and we’ve been successful in doing it.”

That 100 feet of elevation in Lake Mead, he said, represents a little over 8 million acre-feet of conserved water.

“And Arizona itself has done 4.6 million acre-feet of that 8 million,” said Director Buschatzke.

The Director emphasized his primary message as it relates to the river-management negotiations: Everyone who benefits from the river needs to contribute to conservation efforts on the river. His Upper Basin counterparts have rejected proposals to share any Colorado River water conservation efforts, he noted.

In a luncheon address preceding the Director’s keynote, Arizona Governor Katie Hobbs observed the importance of cooperation and collaboration in reaching agreement.

“Collaboration is the foundation of water policy and management discussions in which Arizona is on the cutting edge,” Governor Hobbs told conference attendees.

Collaboration proved a key element in two of the most important water-rights settlements in recent Arizona history.

Under Governor Hobbs, the State in 2024 concluded two tribal water settlements including four Native American tribes – settlements that concluded Arizona’s involvement in water-rights negotiations that in some cases had lasted decades.

I was at the Getches-Wilkinson Center & Water and Tribes Initiative shindig this week live-posting on BlueSky (Click the “Latest” tab). The question of whether the negotiators from the seven states were being candid about their proceedings came up. Colby Pelligrino described her frustration with folks jumping all over every proposal as unfair or damaging to their rights. They can’t make any progress towards building a solution if every proposal is prevented from going forward.

Also, Eric Kuhn, maintained that since the Colorado River Compact was written for a river that doesn’t exist any longer parts need to be reworked. He emphasized living with the river we have.

Chuck Cullom let everyone know that the data the negotiators are working with is available.

Concerningly low amounts of water are flowing from Rocky Mountain snowpack this spring, a summer of drought looms across swaths of the West, and the negotiators tasked with devising a sustainable long-term water plan for the 40 million people who rely on the Colorado River are running out of time. Commissioners from the seven states in the Colorado River Basin — Colorado, New Mexico, Wyoming, Utah, Arizona, California and Nevada — must create a plan that will govern how those states divvy up the river’s water after the current guidelines expire at the end of 2026. As the river shrinks due to drought and climate change, the negotiators must decide who will take less water — and they need to do so in the next few months.

“The way the law of the river is set up, this is a decision that takes the seven states, and there are so many stakeholders and users who depend on that,” said Jennifer Pitt, Colorado River program director at the National Audubon Society. “We are really at their mercy and we are just about out of time.”

The negotiators, who met in Las Vegas this week, have repeatedly said they are committed to finding a consensus solution, but have not yet done so and have already blown past previous deadlines set by federal authorities more than a year ago. JB Hamby, California’s negotiator, said in an interview that the states have been meeting several times a month since December, when tensions between the states burst into public view during a conference. Both the frequency and the tenor of the meetings have since improved, he said.

Those who depend on the river are already dealing with uncertainty: this season’s mountain snowpack is expected to deliver about half the median amount of water to the system’s two major reservoirs, which are already two-thirds empty. Years of drought not balanced by decreases in water consumption have drained Lake Mead and Lake Powell, and aridification fueled by climate change is expected to continue to reduce the flow of the river that makes modern life possible across the Southwest. The Colorado River irrigates more than 5 million acres of farmland — including water supplies for much of the nation’s winter vegetables — and comprises large portions of many Western cities’ water portfolio, said Brad Udall, senior water and climate research scholar at Colorado State University’s Colorado Water Institute.
