As Lake Powell dropped to its lowest-ever level Friday — a decline that has forced dam tenders to unexpectedly release 125,000 acre-feet of water from Flaming Gorge Reservoir — Wyoming stood behind five projects that could divert tens of thousands more acre-feet from waterways in the troubled Colorado River Basin.
Powell’s surface elevation dipped to 3,555.09, lower by 12 hundredths of an inch than the previous post-completion nadir of April 8, 2005. The new benchmark is “probably worth noting,” Wayne Pullan, the U.S. Bureau of Reclamation’s Region 7 director, said in a press call Wednesday.
“The fact that we’ve reached this new record underscores the difficult situation that we’re in,” he said.
Friday’s mark amounts to a 150-foot drop in the storied Utah-Arizona reservoir over 24 years, a decline that’s spurred action to preserve irrigation flows, millions of dollars in hydropower revenue and myriad necessities for 40 million people in the West.
As the BOR began its “emergency” release of 125,000 acre-feet from Flaming Gorge Reservoir on July 15, a coalition of downstream water users called for a moratorium on new dams and pipelines.
“New diversions are going to increase the depth of this crisis and the impacts on the 40 million users,” said Steve Erickson, a board member with the Great Basin Water Network. “The [moratorium] idea is: ‘Let’s all take a deep breath and start talking to one another [about] what this amounts to.’”
In an era of drought, aridification and climate change, new water projects will be closely scrutinized, Pullan said.
“Any complete analysis of new projects, would need to really take into account what the impact will be on operations … in the larger picture.”
Meantime Gov. Mark Gordon announced he will appoint a drought working group to ensure “local perspectives on issues that impact our water users and the State” are heard when planning for a crisis that “may last for years.”
Wyoming will not be deterred from its water development goals that would store, divert or otherwise use another 115,000 acre-feet in the upper reaches of the 246,000-square-mile Colorado River system, top officials told WyoFile.
“A pure, strict moratorium flies in the face of rights held by all seven [Colorado River Compact] states,” said Pat Tyrrell, Wyoming’s member on the Upper Colorado River Commission. “I would have a hard time recommending that Wyoming get itself in that position.”
The Bureau of Reclamation has a limited say in what Wyoming can do with its water and development, state Senior Assistant Attorney General Chris Brown said.
“They certainly don’t get to say ‘no,’” he said. “They certainly don’t have that authority in Wyoming to decide how Wyoming wants to develop its water.”
Task 1: Lake Powell
The immediate goal — of both the BOR and Wyoming — is to maintain a sufficient level at Lake Powell to generate power valued at about $120 million a year and also meet obligations to downstream users. Doing so, Gordon said, will help ensure that Wyoming’s residents get their shares of water under Colorado River Basin laws and compacts.
Those agreements were forged under the now-questionable assumption that there would be at least 15 million acre-feet annually to divide among upper and lower basin states – Wyoming, Utah, Colorado and New Mexico upstream and Arizona, California and Nevada below. However, “there isn’t 7.5 million acre-feet available to the upper states,” said Mark Squillace, a professor of natural resources law at the University of Colorado Law School.
“The problem is that the river provides only between 12 and 13 million acre-feet of water today,” he told WyoFile. “The reservoirs on the Colorado River system have far more storage capacity than they can use, so building additional storage capacity does not seem to make much sense.”
He reserved judgment on the merit of individual water-storage projects but said damming a river and creating a reservoir doesn’t give the state any greater claim to that water.
“At the end of the day, this is problematic for the whole Colorado system,” he said, “there just isn’t capacity any more.”
Members of the Great Basin Water Network last week said instead of damming rivers, it wants to “damn the status quo” that too easily supports water diversions. The group is particularly focused on Utah’s Lake Powell Pipeline, which would divert 84,000 acre-feet annually to the St. George area. But its call for a basin-wide development moratorium is necessary “before everybody dives in to grab what they can,” board member Erickson said.
“You can’t get enough water out of the river to do all those things,” Erickson said of current proposals that envision everything from expanding cities to irrigating more land. “We would want to evaluate each project on its own merits,” he said. A moratorium would help prevent investments in what “may turn out to be stranded assets.”
The group wants the public to pay keen attention to the federal infrastructure bill and other post-pandemic aid packages where, as the network group’s executive director Kyle Roerink said, “there are a lot of opportunities for skullduggery.”
Declining ‘a lot quicker’
Lake Powell’s drop of 150 vertical feet since 1997 represents a loss of 16 million acre-feet, enough to support 64 million suburban households, BOR regional director Pullan said last week. Although the reservoir is about 423 feet deep at the dam today, its martini-glass-shaped profile means Powell now holds only about 32% of its capacity.
The latest declines came “a lot quicker than we imagined,” Pullan said, forcing the agency to release flows from Flaming Gorge under the authority of a Drought Response Operations Agreement forged with upper division states. Flaming Gorge will contribute 125,000 acre-feet through October while dam tenders will release 56,000 acre-feet combined from Colorado’s Blue Mesa and New Mexico’s Navajo reservoirs this year. The total of 181,000 acre-feet should raise the water level in Lake Powell by about 3 feet, Pullan said.
Powell’s elevation Sunday, the latest available, stood at 3,554.72 feet, not quite 20 feet above the critical hydropower minimum elevation (and 35-foot buffer) of 3,525. But the Bureau’s most recent forecast is dire.
“Our 24-month [forecast] shows that you will fall below that 3,525 elevation in the spring,” Pullan said. It’s uncertain how that will affect Wyoming and the other upper division states’ obligation not to diminish the delivery of an average of 7.5 million acre-feet to Lee Ferry, the measuring point just below Lake Powell’s Glen Canyon Dam.
Drought contingency planning — part of what Gov. Gordon wants his task force to be involved with — might first seek voluntary reductions before irrigators or others start to see diversions cut off. Demand management could forestall mandatory curtailment, which would be done according to priority of water rights, the oldest rights being superior and the last to be diminished.
New storage projects in the 1,450-mile long basin are going to live and die on their own merits, Pullan said, “and whether they make sense.”
“Depending on how those are operated, they may degrade our ability to fill those [Powell and Mead] reservoirs or they may enhance our ability to fill those reservoirs,” he said.
The BOR might be part of the environmental review process for water storage projects in the basin, he said, including Wyoming’s five planned projects. The agency would “absolutely” look at each in light of today’s dwindling water supply.
“In this, we bring all of the expertise and knowledge we have,” he said of any review. “It would be informed by our last survey,” or forecast.
The BOR’s releases to prop up Powell’s water level will be undertaken within environmental safeguard parameters, Pullan said. Gordon also is committed to “maintaining environmental commitments,” he said in announcing the Wyoming task force.
Five water projects
Construction plans in Wyoming call for a new dam that could release an additional 9,400 acre-feet annually from New Fork Lake. The Big Sandy Dam is scheduled to be raised to hold back another 12,900 acre-feet for irrigation. The state is reconstructing the Middle Piney Dam to impound 3,370 acre-feet there. All three are in Sublette County.
At Fontenelle Reservoir, located mostly in Lincoln County, Wyoming is negotiating with the bureau for access to 80,000 acre-feet that’s historically not been used. Above the Little Snake River in Carbon County, irrigators want to build a 280-foot-high concrete dam to impound 10,000 acre-feet on the West Fork of Battle Creek.
All told, the Wyoming projects in the Green and Little Snake river basins, subsets of the Colorado River Basin, would cost about $123 million. Much of the water proposed to be held back would be used for irrigation, with some exceptions.
Fontenelle water could be used to meet Wyoming’s compact obligations, officials have said. But there would need to be “some huge level of demand” before that water would be needed, Tyrrell said.
At the West Fork of Battle Creek, the project calls for a minimum 2,000 acre-foot pool and 1,500 acre-feet earmarked as a “bypass flows” for river health. Between 67 and 100 irrigators would benefit from another 6,500 acre-feet held annually behind the proposed $80 million project, according to plans.
Colorado River compacts say Wyoming has water to develop. If the state were to use its entire share allocated under the river laws — 14% of 7.5 million acre-feet annually — that would amount to 1.05 million acre-feet. Wyoming’s average annual usage, however, is only about 548,000 acre-feet, Tyrrell said.
Obligations to lower-division states are based on a 10-year average and the upper states are surpassing their 75-million-acre-feet commitment. “Our current 10-year running average is about 88 million acre-feet,” state attorney Brown said.
“We feel [curtailment is] at least not coming in the near future,” Brown said. Unless, he added, Powell eats through its 35-foot hydropower buffer, falls below elevation 3,490 “and we have trouble actually releasing water.”
Wyoming’s average annual usage of 548,000 acre-feet is less than the amount of water the state has authorized through permits for beneficial use, he said. “We don’t use near as much as has been adjudicated.”
Another twist favors Wyoming. “Most of our irrigation rights are pre-compact,” Brown said, meaning they would not be subject to curtailment under Colorado River laws and agreements. Most municipal and industrial rights are post compact, he said.
Different impoundments might be operated differently from one another during years when water is short, Tyrrell said. Middle Piney, for example, will hold pre-compact water rights not subject to restrictions. The enlargement of Big Sandy, however, would create a new right, junior to others.
“That’ll come under a more recent priority date, and it won’t be allowed to fill if we are, for example, under any kind of curtailment,” Tyrrell said.
At other impoundments, stored water could be used to meet downstream obligations if such was the intent of its builders.
“It depends on beneficial uses for which that storage is granted,” Tyrrell said. “It would have to say something like ‘compact compliance’ on there.”
Neither Brown nor Tyrrell sees a conflict between storing and diverting more water in Wyoming’s part of the Colorado River Basin and downstream struggles.
“Much of this water finds its way ultimately down to Lake Powell and to Lee Ferry [the critical measuring point between the upper and lower states] through return flows, through late-season flows and the benefits associated with that,” Brown said. Return flows are excess irrigation water that goes back into the river, sometimes directly and other times through wetlands and springs.
“Water just doesn’t automatically get lost to the system,” he said, and storing it high in the basin, rather than in the desert, might save some of it from evaporating. “The idea that these [uses] have a net detrimental impact on the system as a whole, I think, is probably a conclusion too easily jumped to,” Brown said.
“Having additional diversions being somehow contrary to the dropping elevations Lake Powell and Lake Mead is not a one-for-one thing, by any stretch of the imagination,” he said, “and perhaps not a detriment at all but a benefit.”
The two emphasized a couple of points.

“Generally, at least historically, the lower basin has overused its apportionment,” Brown said. “And so it’s difficult to make a blanket statement that applies with some equity all the way across the basin.”
Wyoming will honor applications for new diversions, Tyrrell said.
“If somebody comes into the state engineer’s office tomorrow [seeking] a permit to irrigate 200 acres outside of Pinedale,” he said, “they’re going to get their permits.”
California and three other states have more water than any other western state will ever have, it’s called the Pacific Ocean. Instead wasting precious agricultural water on swimming pools, big lawns, golf courses and so on.
They can take their wind turbines and solar to power their pumps on RO plants. They can also pipe water to Nevada and Arizona. They should have had this figured out a long time ago. Where are the so called experts, where are they? Wyoming needs to keep every bit of it’s water, do it’s projects. Once give water away we will never get it back. I’m mad at the stupidity and the greed.
This whole business is pretty much moot. We’ve already, irreversibly, done ourselves in–with our own wastefulness and greed. Soon we’ll be gone and forgotten, though we surely will have left our junk behind, around the planet…and in space. ET might find our example instructive, that is, if it ever shows up.
Great comments everyone. I just want to point out the other drainages in Wyoming since the Green/Colorado seems to get most of the attention due to down stream usage in the lower states,
– the north Platte is managed under the 4 state court ordered compact and we have extremely important water storage dams in Wyoming which serve multiple uses,
-the Belle Fourche River is impounded at Keyhole reservoir primarily for irrigation needs in South Dakota from Belle Fourche to St. Onge,
-the Cheyenne River has only small impoundments on it in Wyoming but is impounded at Angostura reservoir near Hot Springs, Sd,
-the Snake River in Teton County is well known and ultimately contributes to the Columbia River with its massive dams and electricity generation,
-the Powder River flows north into Montana and empties into the Yellowstone, some smaller impoundments in Wyoming,
-the Tongue River also flows north into the Yellowstone and has impoundment in the Tongue River Reservoir,
-the Wind River/Big Horn River has important impoundment in Boysen Reservoir but is unique in that the Federal Courts awarded the Shoshone/Arapahoe tribes 500,000 acre feet of annual water rights due to the Fort Laramie Treaty of 1868 – the Big Horn is further impounded at Yellowtail just outside of Lovell and flows north to the Yellowstone – the Crow/Cheyenne tribes were also awarded an additional 500,000 acre feet of annual water rights due to their Fort Laramie Treaty of 1868,
-the Little Missouri?? flows north out of Campbell County into Montana and thence North Dakota before emptying into the Missouri in ND,
– the Little Snake River originates in Wyoming with some storage here and ultimately contributes to the Colorado River flow,
There may be others I am not aware of, but the point is that each drainage is unique in its own way and is administered somewhat differently. The Green River/Colorado drainage currently gets all of the publicity due to drought and down stream heavy usage, but we should keep in mind that these other drainages are just as important in their own counties.
Water is NOT a zero sum game. Meteorology will continue to produce floods, freezes, and droughts. A drought focuses the mind on that precious blue water, and is precisely the best time to build new dams.
The Wyoming economy is under attack from all directions: extraction, grazing, timber, tourism, energy, as well as transportation. Now the threats include restricted water impoundment and even Electro-Magnetiic-Pulse (EMP) threats from China.
Hydroelectric Alternators shielded by concrete, steel, & water are virtually impervious to solar & manmade EMP. Water is life. Build the dams!

”Sunday Morning” a TV magazine, had a segment on this subject and reflected the same consequences as this article. Today we are predicted to hit 90+ all week long with other Wyoming cities in the 100’s. Outlook for wetter years are pesimistic due to climate change.
The climate change deniers had better change their attitude and help solve this delimma. The science of climate change can’t be challenged as 99% of climatologists agree that “climate change” is indeed a fact. Coal and fossile fuel autos are the main factors but bought and paid for polititions won’t help with solutions.
Phoenix has over 230 golf courses. They have aquired the water rights from most of the agriculture interests and need more. Irrigaters in Califirnia, where a good portions of our food is grown, have lost 25% of their water and stand to loose more if current trends continue. Are we going to have to choose between golf or food?
We better wise-up and quickly!.
Thanks to Angus for very informative and important article. I have a question about the Great Basic Water Network.
From the article: “The group wants the public to pay keen attention to the federal infrastructure bill and other post-pandemic aid packages where, as the network group’s executive director Kyle Roerink said, “there are a lot of opportunities for skullduggery.” What did he mean? That the network is opposed to the federal infrastructure bill?
If this is the correct interpretation of his “skullduggery” comment, I hope the Wyoming public will write letters to Mr. Roerink supporting the infrastructure bill and asking that partisan politics not be allowed to interfere with a timely and comprehensive response to our serious water crisis, which I believe is another result of climate change. We need Federal support for a regional adaptation plan.
Candra Day, Great Basin Water Network is a pretty decent group. It fought against Las Vegas’ attempt to remove vast quantities of water from the entire southeastern quadrant of Nevada for more development. The water grab would have desertified the whole area and put ranchers out of business there and in the southwestern quadrant of Utah, and disturbed the entire water table underground. I don’t know what Kyle meant, but he’s not one of the bad guys, and GBWN is definitely one of the good guys.
Riparian law is one of the most difficult and exasperating bodies of law to work through. Over two thousand years ago the Roman Empire knew the importance of water , especially when it came time to use it for a variety of purposes to serve many different users , everything from cattle market stalls to the famous Roman bath houses. The Roman Aqueduct system was impressive for its age, since Rome itself had already run out of local water in 300 B.C. which is why they built 11 aqueducts. More importantly the Romans created water law along the way.
We’re still trying to figure that out two millennia later : how to legally apportion surface water. It’s a work in progress. The Colorado River Compact of 1925 is a solid case for how NOT to do it , IMHO. Water fights can range from brawling over a few thousand gallons of the stuff all the way to millions of acre feet.
Here’s a damning case of the consequences of a flawed Colorado River plan. Maricopa County – Phoenix was platted with curb gutter water sewer etc decades ago to accomodate 15 million people. The Greater Phoenix metro area currently supports 5 million residents ( winter snowbird count) and 400 golf courses. Where would all that extra water come from for another 10 million people , if the Colorado River is already tapped out and the local aquifers are dropping alarmingly ?
My question is simple, drawn from the tap of common sense. Why is available water not apportioned on a percentage basis , factored to the actual available water , rather than hard coding in absolute volumes of water for distribution ? It’s obvious runoff and streamflows vary widely across the years, but the allocations stay fixed. That is illogical.
We have the tech to apportion out the Colorado Basin water in any increment we want in real time , by several methods. It’s long past the time to reformulate the Colorado Compact to reflect actual water available, instead of adhering to absolute volumes that were determined a century ago during some unusually wet years which inflated expectations to a fault.
Again . we will necesarily have to move to adjudicating water by percentages of actual available water, not political high water marks and absolute acre-feet laid down in the time of Warren G. Harding , he of Teapot Dome fame. . To say Climate Change makes that an imperative is a severe understatement. Or put another way about the inevitable horrendous fights over water coming our way — all those Mad Max movies may in fact be training films for coping in a world without enough water to go around.
“The Colorado River Compact of 1925 is a solid case for how NOT to do it”
Water law in the USA goes back further and times have changed. They are a perfect example of why China will eat our lunch if we can’t get a handle on basics like water.
I just don’t get it. Farmers are subsidized to let their ground set and not produce crops. they are paid by the government to do this. These farms have allocated water shares. the government then says that the farms have to use their water shares in order to retain them. the farmers then water empty fields to maintain their shares. Government what a screw up. Poor management!!!!! Kennecott, the worlds largest open pit mine is contracted for so many water shares. Most of these shares are not used. In order to prevent a law suit the water is still delivered and unused. When will people really address the problem. A drought should be measured by lack of percipation not by resivour discharge. Poor management. The levels of water received in the west recently is slightly less then the past. The same water that Adam and Eve used is still here and it jus recycles. With poor management we just need to relocate the water where it is lacking. $$$$$$$ yes
