Increasingly bleak forecasts for the Colorado River have for the first time put into action elements of the 2019 upper basin drought contingency plan.
The 24-month study released in January by the Bureau of Reclamation, which projects two years of operations at the river’s biggest reservoirs, showed Lake Powell possibly dipping below an elevation of 3,525 feet above sea level in 2022. That elevation was designated as a critical threshold in the agreement to preserve the ability to produce hydropower at Glen Canyon Dam.
In a letter to water officials in Colorado, Utah, New Mexico and Wyoming, the Bureau of Reclamation’s Wayne Pullan and Jacklynn Gould said the “minimum probable” forecast triggers “enhanced monitoring and coordination,” and instructed states to identify point persons to take part in monthly planning calls. Those meetings have yet to be scheduled.
“It’s really about giving people an advanced warning,” said Eric Kuhn, former general manager of the Colorado River District, and one of the architects of the 2019 plan.
The forecast in question is called the “minimum probable” forecast, one of the more pessimistic possible futures on the river that supplies water to 40 million people across seven U.S. states and two in Mexico. But the model makes clear it’s plausible that Lake Powell could see rapid declines within the next two years, Kuhn said, and water managers need to consider all possible scenarios and plan for them.
“We need a cushion, and time to react,” Kuhn said. “So the 3,525 (elevation) was put in as a way to give everyone time to think about what’s happening.”
If federal models show the reservoir’s elevation declining past that threshold under the “most probable” forecast, smaller reservoirs upstream in the four Upper Basin states could release water to prop up Lake Powell. The models don’t show that scenario as the likeliest to occur yet…
As exceptional drought conditions expanded to more than 65% of the watershed’s total land area in 2020, operational forecasts for the Colorado River have worsened dramatically. Between Oct. and Nov. 2020, Bureau of Reclamation models projected a possible one million acre-foot drop in Lake Powell’s water storage due to lagging snowpack totals and record-setting soil moisture deficits.
“That was the first glimmer we could be looking at this way earlier than we expected,” said Amy Haas, executive director of the Upper Colorado River Commission.
The drought contingency plans place much of the authority to direct the response in the Department of Interior Secretary. While Rep. Deb Haaland of New Mexico has been nominated for the post, the position is currently vacant. So too is the position of Bureau of Reclamation commissioner, which means much of the drought response coordination is happening at the regional director level, something the drought contingency plans allowed for, Haas said.
From Yale Climate Connections (Jan Ellen Spiegel):
The region is transitioning to a more arid climate, challenging longstanding practices of water-sharing in the basin.
Colorado is no stranger to drought. The current one is closing in on 20 years, and a rainy or snowy season here and there won’t change the trajectory.
This is what climate change has brought.
“Aridification” is what Bradley Udall formally calls the situation in the western U.S. But perhaps more accurately, he calls it hot drought – heat-induced lack of water due to climate change. That was the core of research released in 2017 by Udall, a senior climate and water scientist at Colorado State University’s Colorado Water Center, and Jonathan Overpeck at the University of Michigan.
Their revelation was that the heat from climate change was propelling drought. “Previous comparable droughts were caused by a lack of precipitation, not high temperatures,” the study said. And all the factors at play were having compounding effects on each other that made the situation even worse. Those impacts were being felt most acutely on the biggest water system in the West – the Colorado River Basin.
Without a dramatic and fast reversal in greenhouse gas emissions to slow climate change, Udall and Overpeck said, the additional loss of flow in the basin could be more than 20% by mid-century and 35% at the century’s end – worse than currently assumed.
“I always say climate change is water change,” says Udall, whose father was Arizona congressman Morris (Mo) Udall, an iconic environmental activist. “It means too much water, not enough water, water at the wrong time. It means reduced water quality. You get all of these things together as the earth warms up.”
In Colorado it’s all pretty much coming true. The drought is the second worst 20-year period in the past 1,200 years, according to Udall. This summer/fall alone had some of the hottest spells on record and the worst wildfire season ever. On the other hand, 2013 brought catastrophic floods to the Front Range. “I got 17 inches of water in my house here in four days. It’s all part of the same change,” Udall says.
It’s forced Colorado to start facing the reality that its perpetual struggle for water can no longer be written off as cyclical weather that will all balance-out over short periods of time. It’s climate change at work, and it requires long-term planning and likely fundamental changes to the paradigm of how the state gets, uses, and preserves its water.
The state and individual municipalities are beginning to address their new reality with policies that range from the obvious – conservation, just using less water, to the more innovative – considering using beaver dams to restore mountain wetlands and generally remediating the landscape to better handle water.
But all those actions and more must face the political reality of the longstanding way water-sharing is handled in the basin. It pits state against state, rural against urban, agriculture against, well, everyone.
The Colorado River Compact
The Colorado River Basin provides water to a massive swath of the Rocky Mountain and western states. The Compact that rules it dates to 1922, with California, Nevada and Arizona – the lower basin states – essentially getting first dibs on water that flows from upper basin states – Colorado, Wyoming, New Mexico, and Utah – with secondary access to the water, so they generally absorb the brunt of water losses.
Colorado is a headwaters state – where the river flows down from the continental divide. It relies on whatever falls out of the sky: It does not have the luxury of access to whatever water may flow in farther downstream.
A process to re-evaluate aspects of the Compact is underway with a 2026 deadline. No one expects the basic structure to change, though other contingencies are likely to be layered on, as has happened a number of times in the intervening years.
River levels are off some 20% since the Compact was initiated, compounding the water crunch while the region’s population has grown dramatically, especially in Colorado. That combination of factors have many water experts and administrators convinced any new strategy has to do more than divvy-up the water differently.
That’s because it’s climate change and not cyclical weather causing the problems, Udall says emphatically: “Yup. Yup. Yup.” He notes that scientists already see impacts they hadn’t expected to see until 2050.
“I think some of the predictions about reduced flows in the Colorado River based on global warming are so dire it’s difficult to wrap your brain around them. We have no operating rules for that kind of reduction in supply,” says Anne Castle, a senior fellow at the Getches-Wilkinson Center for Natural Resources at the University of Colorado. “Even with these discussions that will be taking place over the next five years for the Colorado River system, I’m not sure that they will be able to get to an agreement about what would happen if flow is reduced by 50%.”
The critical climate change impacts seem to act in a loop: heat causes more evaporation of surface water. The resulting lower water level means water will warm more easily, and in turn evaporates more readily.
Global warming is also changing the dynamics of snowpacks. They melt faster and earlier and don’t regularly continue to slowly dissipate, creating a gradual runoff that is more beneficial and sustaining to the water supply. Udall notes that on April 1, 2020, there was 100% of normal snowpack above Lake Powell, which with Lake Mead are the two enormous reservoirs in the system. In a normal year that would provide 90-110% of runoff. But it provided only 52% in 2020 as a result of dry warm weather through fall.
Sustainable water supplies are also threatened as weather events occur more often as extremes: major rains in a short period of time sandwiched by extended dry periods. Torrential rains that follow a long drought may help the soil, but runoff may never make it to the water supply.
Wildfires, in recent years larger and longer, complicate matters by dumping ash and crud into water bodies, which results in less water and contamination that can render unusable what water there is. And if difficult climate conditions keep trees from growing back after fires, the resulting ecosystem changes could further damage water supplies.
Big ideas in place
“This is not your average variability,” says Andy Mueller, general manager of the Colorado River Water Conservation District, which covers most of the water used by the state. “Cooperative management of water resources can really help in these hot dry summers,” he says.
Mueller says the district tried releasing additional water from a reservoir that also creates hydropower. The extra water helps cool the river it flows into – slowing evaporation and allowing fishing and other activities often stopped when the water gets too warm and low to resume. That same water was also used for other hydropower plants downstream. Some then continued to other river areas. And some was diverted for crop irrigation, important given that farming and ranching are the biggest consumers of water in the state.
Basic conservation – just using less water – is always the first step, but even Colorado Water Conservation Board senior climate specialist Megan Holcomb admits: “We’re definitely beyond that conversation.”
The Board is considering systems that employ the technique of demand management: finding ways to use minimal water to allow for storage for dry years. So far, the thinking involves a voluntary program.
Already in place is an online tool called the Future Avoided Cost Explorer or FACE: Hazards. It helps quantify impacts of drought and wildfires on sectors of the Colorado economy.
“We know these hazards are going to continue to impact our economy, but we have no numbers to even say how much we should invest now so that we don’t have financial impacts in the future,” Holcomb says.
Castle talks about ideas such as consideration of water footprints on new developments and re-developments; integrating land use planning with water planning including things such as landscaping codes; and use of technology at various levels of water monitoring.
In search of more equitable sharing of water
She notes also a drought contingency plan adopted in 2019 by the Compact states calling for reductions in deliveries to the lower basin. It’s pointed in the right direction, she says. “At the same time pretty much everyone involved in those discussions and that agreement also agreed that it was not sufficient,” Castle says.
Many experts have called for more equitable sharing of water reductions. But ideas on what is fair differ from state-to-state and also among different groups within a region where some interests are pitted against agriculture, which accounts for 80% of the water usage in the basin.
“I think people look at that huge volume of water being used in irrigated agriculture as a place where there’s flexibility. And when you get to the politics of working through that in an equitable way, it gets really complicated,” says Jennifer Pitt, Colorado River program director for the National Audubon Society.
The suggestions have included crop switching or alternative transfer mechanisms that call on farmers to periodically grow less water-intensive crops, or pay them not to grow, as a way to make water available for municipal use or storage.
“From a pure economic perspective, it may seem like you pay them and they’re whole,” Udall says. “There are actually a lot of things where they don’t get whole. They potentially lose a market that they’ve established over years and a great relationship with a buyer. And if that goes away for a year, that buyer may not come back.”
In the end, experts say people in the Southwest should definitely not count on more precipitation arriving to bail them out. “I would disabuse people of the idea that you’re going to get more water,” Udall says. “I think it’s pretty clear you’re going to have less water.” So for folks who think building more reservoirs is a solution, Udall says: “It’s not at all clear to me that that works.”
But less conventional strategies just might.
Beaver dams to the rescue?
Beaver dams are a water management technique that has worked in nature for eons – at least for beavers. Sometimes for people? Not so much.
But the thinking is they could help slow water loss from high-elevation wetlands. That includes the real deals built by beavers or human-constructed beaver dam alternatives.
“We think there’s a possible synergy there that helps to improve water supply for water users and helps to improve habitat conditions for species – birds in particular – that depend on that kind of wetlands being around,” Pitt says.
The goal would be to protect remaining ones, help establish new ones, and do the same for high-elevation meadows.
A lot of research is still needed, Pitt says. “There’s all kinds of instrumentation that has to go into place to understand the groundwater, the surface water, evaporation, the water balance, what it does to your river downstream,” she says. There are water law considerations. And then the inevitable pilot projects.
Overall, she says, this type of holistic approach to water through natural ecosystem restoration could become a component of water-sharing agreements as have already been done with Mexico. In exchange for getting river areas restored to better flow, Mexico agreed to a sharing agreement it might not otherwise have.
More people, less water, and a touch of Johnny Appleseed
More people and less water has forced Denver Water to work with uncertainties not previously considered. “Variability is the name of the game in Colorado,” says lead climate scientist Laurna Kaatz. “And that variability’s going to increase over time. That makes it incredibly challenging to continuously provide high-quality drinking water when you’re not sure what’s coming around the corner.”
The situation calls for adaptive capacity, she says, to provide technical and legal flexibility to adjust for changing circumstances.
Kaatz pointed to the One Water project that pairs water with usage. For instance, treated wastewater could be used to water a golf course, saving the purest water for drinking.
Another project is called From Forests to Faucets, which works on watersheds as natural infrastructure to optimize water flow. It has already proved successful at keeping a wildfire in 2018 from encroaching on a reservoir. In April, Denver Water plans to expand its Airborne Snow Observatory, which uses technology developed by NASA to track snow availability, but now it can be deployed above an altitude of 8,000 feet.
Together the efforts seem to be working – since the 2002 drought, Denver Water has maintained a 22% per-person reduction in water usage from pre-drought levels.
Steamboat Springs is opting for tree-planting. The idea is that trees will help cool down the Yampa River, which is part of the Colorado River Basin. Hot, dry seasons had been pushing stream temperatures so high that part of the river wound up on EPA’s impaired waterbody list.
“That was a call to action,” says Kelly Romero-Heaney, Steamboat Springs’ water resources manager.
The timing also dovetailed with the 2015 release of a Colorado Water Plan that included goals for stream management. Steamboat Springs did a streamflow management plan – released in 2018. In it was the idea of shading the Yampa.
“What we learned was that flow alone cannot overcome the thermal load for the solar radiation, as strength of that radiation increases over time,” she says. “The more that we can prepare the river for that, the better it will buffer against the impacts of climate change.”
They joined forces with the Yampa Valley Sustainability Council’s ReTree program that began in 2010 as a reforestation effort to counteract trees killed by pine beetle infestations. It morphed into a three-year Yampa River restoration.
“That work also increases resilience to future changes,” says Michelle Stewart, the council’s executive director. “We’re really learning the important role soil moisture plays in resilience.”
ReTree planted 200 narrow leaf cottonwoods in 2019 and another 350 this past October. This coming October, its plans are for 450 cottonwoods and 150 mountain alders. All were raised at the Colorado State Forest Nursery from Yampa Valley clippings. “We’re using local trees that are already kind of adapting to big swings in temperature and probably have a little bit more of that hardiness that we need and drought readiness,” she says.
It’s too early to know how the shading is working but there are plans for citizen help to monitor that and to implement a soil moisture monitoring network in the Yampa Basin.
“This is a Johnny Appleseed project,” says Romero-Heaney. “We plant today and hopefully my children will get to enjoy it.”

FromS&P Global Market Intelligence (Richard Martin):
In an era of perennial [aridification], when the future of the Colorado River watershed, the lifeline of the U.S. Southwest, is the subject of fierce debate in state capitols across the region, the idea of bringing more than 26 billion gallons of water a year to a community of fewer than 200,000 people on the edge of the Mojave Desert strikes many as folly. To officials in Washington County, of which St. George is the county seat, though, it is a critical resource for the future.
Currently the county has one primary source of water, the Virgin River, said Todd Adams, director of the Utah Division of Water Resources, and more will be needed in the coming decades.
“They only have one water source, and they have potential vulnerabilities with the Virgin River,” Adams said in a recent interview. “They need a second reliable source.”
What’s more, St. George, a bedroom community about 120 miles from Las Vegas with more than a dozen golf courses, lavish resorts and a high percentage of retirees, is expected to continue to grow rapidly through mid-century. To serve all those new arrivals, and all those fairways, more water will have to be imported, say local and state officials.
“Based on the population growth projections for Washington County through 2060, it’s expected to triple in size to over 500,000,” said Adams. “And with that growth, additional water sources will be needed.”
The problem is that taking water from one part of the Colorado River watershed diminishes the water available for other parts. And long before St. George reaches its ultimate population level, there may not be enough to go around…
Approved by the Utah state legislature in 2006, the Lake Powell Pipeline has become one of what opponents and environmentalists have dubbed “zombie water projects”: proposals for diversion and transportation in the Colorado River watershed that face significant opposition and may never get built, but that refuse to die.
The pipeline was originally pitched as a source of water and power generation. The initial plan called for a large hydropower generating station along the route and a reservoir for pumped energy storage, but those elements were scrapped to reduce the environmental impact of the overall system, according to Karry Rathje, a spokesperson for the Washington County Water Conservation District. The line will still include six smaller inline hydropower facilities, to manage the water pressure and to reduce the electricity load from the pipeline on the regional grid. Those stations will total 85,000 MWh of generation annually, at full capacity; the full project will consume around 317,500 MWh, making it a net consumer of 232,500 MWh a year.
Reducing the amount of water in Lake Powell, though, could affect electricity production at the two major downstream hydro stations on the Colorado, at Glen Canyon Dam below Lake Powell, built in 1964, with 1,312 MW of generation capacity, and the two plants at Hoover Dam, built in 1936, with a combined capacity 2,078 MW, below Lake Mead. Both dams have become symbols of the 20th-century conquest of the Southwest and of the human depredation of the Colorado River ecosystem. Glen Canyon, in particular, was controversial from its conception; environmentalists today loudly demand its removal…
Together, the two dams produce enough electricity to feed roughly 630,000 homes across the region. Because hydropower generation is dependent on the volume of water stored in the reservoirs, as the levels of lakes Mead and Powell fall, electricity production will follow. Lake Powell has been below its average annual elevation every year in this century, according to data collected by Western Resource Advocates; in 2018 the difference was more than 30 feet.
Electricity production from all three facilities has fallen slightly in recent years, and water experts believe the future could be far worse.
“Higher temperatures and altered precipitation patterns” — i.e., the effect of global climate change — are expected to reduce streamflows in the basin by up to 11% by 2075, according to a 2013 white paper by Aaron Thiel of the University of Wisconsin-Milwaukee’s Center for Water Policy. “These factors, combined with increased summer evaporation rates, could reduce reservoir storage by as much 10-13 percent, and ultimately reduce electricity generation by 16-19 percent in the Colorado River Basin.”
Reduced electricity from hydropower could be only one of the obstacles facing big water-diversion projects like the LPP, as policymakers face the new drier, hotter era in the Southwest.
Governed by a complex web of agreements and water rights stemming from the Colorado River Compact of 1922, water use in the basin has long outstripped the actual water available. As the climate warms that gap is sure to expand.
A 2017 paper in the journal Water Resources Research, by Bradley Udall of Colorado State University and Jonathan Overpeck of the Colorado River Research Group, found that “As temperatures increase in the 21st century due to continued human emissions of greenhouse gasses, additional temperature‐induced flow losses [in the Colorado River] will occur.” Those losses could exceed 20% below the 20th-century average flow by mid‐century and 35% by 2100.
And they could be devastating to the region’s economy. According to a 2014 study that was produced by Arizona State University’s Seidman Research Institute and commissioned by Business for Water Stewardship, a non-profit organization, the Colorado River supports $1.4 trillion in annual economic activity and 16 million jobs across the seven states of the basin. Water from the river is essential to at least half the gross economic product in each of those states, including 65% in New Mexico and 87% in Nevada, the economists found. A drop in available water of only 10% would endanger some $143 billion in economic activity in a year.
Businesses everywhere are increasingly vulnerable to the risks presented by inadequate supplies of clean water. The 2019 Global Water Report produced by CDP, a nonprofit organization focused on the environmental impacts of companies, investors and governments, found that, worldwide, the total business value at risk due to water shortages and water pollution reached $425 billion. In the U.S. Southwest, that risk grows more acute with each year of persistent drought…
Despite being identified in a June 2020 executive order from the Trump administration as among the infrastructure projects that should be pushed quickly through the environmental review process, the LPP has sparked near-universal opposition from the other six states of the basin. That opposition crescendoed in September with a letter to the Secretary of the Interior from a coalition of state water agencies and governors’ offices in Arizona, California, Colorado, Nevada, New Mexico and Wyoming demanding that the project be paused or abandoned…
In southern Utah that debate is complicated by a range of factors with origins in the economics and politics of water in the West.
People in Washington County use around 300 gallons of water per capita per day, according to the most recent figures from the U.S. Geological Survey, more than twice the national average and 90 gallons more per capita than residents of Las Vegas, a city of nearly 650,000. And they get their water cheaply: water rates in the county average around $1.50 per 1,000 gallons, less than half of what Las Vegans pay and way below the $5/1,000 gal. that Denverites pay.
Zach Renstrom, the general manager of the Washington County Water Conservation District, disputes those numbers, saying that the state of Utah includes evaporation from reservoirs and re-used water in its water-use calculations…
Still, simple economics indicate that if people in southwest Utah paid more for their water, they would use less.
“Water use in Utah is subsidized, mostly by property taxes,” said Gabriel Lozada, an associate professor of economics at the University of Utah who has extensively modeled the Lake Powell Pipeline project. “So people in urban areas don’t see what the right price of water is. Unsurprisingly, Utah urban dwellers use a lot more water. The price of water we face is way way too low.”
And Washington County residents will eventually have to pay for the new pipeline, after the state fronts the construction costs. That, says Lozada, in turn would raise water rates — thus obviating the need for the pipeline as residents use less water. The possibility of rising prices leading to more conservation, and thus less demand, has not factored, at least publicly, into the developers’ considerations.
“In many scenarios it’s possible for Washington County to raise rates enough to pay back the cost of the pipeline,” said Lozada, “but they’d be so high that demand for water would be so low that no one would want to buy the water in the pipeline.”
Renstrom claims that Lozada and other opponents have an underlying agenda…
The argument over the Lake Powell Pipeline is a proxy for a larger debate about the future of the economy and society in the West, between competing visions of unlimited growth and boundless prosperity, on the one hand, and a new era of scarcity, conservation and more modest expectations on the other.
The biggest consumer of water in the Southwest, by far, is not cities like St. George but big agriculture. Since the early 20th century farmers have been growing water-intensive crops like alfalfa and cotton in the desert, using groundwater and Colorado River water. That era could be coming to a close. As the region urbanizes, converting farmland to towns, average water use goes down. Even a golf course uses less water than an alfalfa farm. A 2015 report on Utah’s future water resources and needs by the state’s Legislative Audit Division found that the Utah Division of Water Resources “understates the growth in the water supply when estimating Utah’s future water needs.”
“The division has not attempted to identify the incremental growth in supply that will occur as municipalities develop additional sources of water,” the auditors wrote. “That additional supply will mainly come from agriculture water that is converted to municipal use as farmland is developed.”
At the same time, municipal water districts in the West, such as Las Vegas, are actually using less water per capita as their populations grow…
“The widespread presumption that population growth means growing water demand drives much of the politics of water planning in the Colorado River Basin,” write Eric Kuhn, the former general manager of the Colorado River Water Conservancy District, and John Fleck, director of the University of New Mexico’s Water Resources Program, in their 2019 history of Colorado River management, Science Be Dammed. “But it is wrong. Simply put, we are consistently using less water. In almost all the municipal areas served with Colorado River water, water use is going down, not up, despite population growth.”
That means the fundamental presumption at the heart of the Lake Powell Pipeline — that in order to grow, Washington County needs more water from the river — is likewise flawed. And it offers hope that as the climate warms and the region dries, it’s possible to forge a new relationship between the Colorado River and the communities that depend on it.
“We have been getting it wrong for a century,” write Kuhn and Fleck. Time to get it right is growing short.
Investor interest in the river could redefine century-old rules for who controls one of the most valuable economic resources in the United States.
There is a myth about water in the Western United States, which is that there is not enough of it. But those who deal closely with water will tell you this is false. There is plenty. It is just in the wrong places.
Cibola, Ariz., is one of the wrong places. Home to about 300 people, depending on what time of year you’re counting, the town sits on the California border, in a stretch of the Sonoran Desert encircled by fanglike mountains and seemingly dead rocky terrain. Driving across the expanse, where the temperature often hovers near 115 degrees, I found myself comforted by the sight of an oncoming eighteen-wheeler carrying bales of hay, which at least implied the existence of something living where I was headed.
Thanks to the Colorado River, which meanders through town, Cibola is a verdant oasis that chatters at dusk with swooping birds. Along both banks, a few hundred acres produce lush alfalfa and cotton, amid one of the more arid and menacing environments in North America.
This scene is unlikely to last, though. A few years ago a firm called Greenstone, a subsidiary of a subsidiary of the financial-services conglomerate MassMutual, quietly bought the rights to most of Cibola’s water. Greenstone then moved to sell the water to one of the right places: Queen Creek, a fast-growing suburb of Phoenix 175 miles away, full of tract houses and backyard pools.
Transferring water from agricultural communities to cities, though often contentious, is not a new practice. Much of the West, including Los Angeles and Las Vegas, was made by moving water. What is new is for private investors — in this case an investment fund in Phoenix, with owners on the East Coast — to exert that power.
When I reached Holly Irwin, a county supervisor who lives in Cibola, by phone a couple of weeks after my visit, she was angry.
“They’re going to make big bucks off the water, and who’s going to suffer?” she said. “It’s the rural counties going up against big money.”
Grady Gammage Jr., a spokesman for Greenstone, said, “In my view there is enough water both to sustain a significant agricultural economy on the river and to support urban growth in central Arizona.”
In the West, few issues carry the political charge of water. Access to it can make or break both cities and rural communities. It can decide the fate of every part of the economy, from almond orchards to ski resorts to semiconductor factories. And with the worst drought in 1,500 years parching the region, water anxiety is at an all-time high.
In the last few years, a new force has emerged: From the Western Slope of the Rockies to Southern California, a proliferation of private investors like Greenstone have descended upon isolated communities, scouring the driest terrain in the United States to buy coveted water rights.
The most valuable of these rights were grandfathered in decades before the population explosion in desert cities like Phoenix and Las Vegas, and privilege water access to small, often family-owned farms in stressed communities. Rechanneling water from rural areas to thirsty growth spots like Queen Creek has long been handled by municipal water managers and utilities, but investors adept at sniffing out undervalued assets sense an opportunity.
As investor interest mounts, leaders of Southwestern states are gathering this month to decide the future of the Colorado River. The negotiations have the potential to redefine rules that for the last century have governed one of the most valuable economic resources in the United States…
Increasingly, the river is threatened by drought, with flows down 20 percent over the last 20 years. As a result, the talks starting in January will be a vehicle for urgent attempts to manage the water, including replenishing downstream reservoirs. By design, the five-year process is ponderous and built to be consensus-driven, with an eye toward shared sacrifice.
Most of the water in the 1,450-mile-long river comes from Colorado, and as that state’s top water official from 2013 to 2017, James Eklund directed the creation of a comprehensive long-term plan to address climate change, the first by a state in the West. He believes that the last best hope against the drought is a market-based solution, one that allows private investors seeking a profit a significant hand in redrawing the map of water distribution in the West.
“I have seen time and again the wisdom of using incentives that attract private sector investment and innovation,” Mr. Eklund said. “Dealing with the threat of climate change to our water requires all sectors, public and private, working together.”
To proponents of open markets, water is underpriced and consequently overused. In theory, a market-based approach discourages wasteful low-value water uses, especially in agriculture, which consumes more than 70 percent of the water in the Southwest, and creates incentives for private enterprise to become involved. Investors and the environment may benefit, but water will almost certainly be more expensive…
The interested players range from financial firms to university endowments to investor groups, including at least two in Colorado led by former governors. T. Boone Pickens, the Texas oilman who died in 2019, was an early evangelist of water buys. Another supporter is Michael Burry, the hedge fund manager portrayed by Christian Bale in “The Big Short,” who made more than $800 million shorting the subprime mortgage market in the mid-2000s.
Matthew Diserio, the president and co-founder of the hedge fund Water Asset Management, has called the U.S. water business “the biggest emerging market on earth” and “a trillion-dollar market opportunity.”
WAM, based in New York and San Francisco, invests broadly in water-related ventures, and one of its core businesses is collecting water rights in arid states like Arizona and Colorado. Since leaving government, Mr. Eklund has become WAM’s legal counsel and public face.
“They’re making water a commodity,” said Regina Cobb, the Arizona assemblywoman who represents Cibola. “That’s not what water is meant to be.”
Private investors would like to bring in or amplify existing elements of Wall Street for the water industry, such as futures markets and trading that occurs in milliseconds. Most would like to see the price of water, long set in quiet by utilities and governments, rise precipitously.
Traders could exploit volatility, whether due to drought, failing infrastructure or government restrictions. Water markets have been called a “paradise for arbitrage,” an approach in which professionals use trading speed and access to information for profit. The situation has been compared to the energy markets of the late 1990s, in which firms like Enron made money from shortages (some of which, it turned out, traders engineered themselves).
Many see the compact as a safeguard isolating the river from the market.
The negotiating states will be focused on restoring the flow of the Colorado River, which has been so diminished by use that from 1998 to 2014 it did not even reach its natural terminus in the Gulf of California. But they will also be looking at rebalancing water levels in Lake Powell and Lake Mead, two federally owned reservoirs that hold water to use in case of extreme drought…
“The reality is we have an overallocated river,” said Jeffrey Kightlinger, general manager of the Metropolitan Water District of Southern California, the largest water supplier in the country. “You’ve got two drivers exacerbating the problem. One, moving very rapidly, is climate change. And you’re still seeing continued growth. So you’re going to see a very important negotiation.”
The emergence of open markets could outpace the negotiations. If states, cities, big farms and utilities were able to buy water freely, especially across state lines, the allocations of the compact could be obviated and the governmental power to manage the fate of the river eroded.
“The Western model is a sort of comprehensive, consensus-based public discussion, and it’s worked very well,” said Bruce Babbitt, a former governor of Arizona and secretary of the interior during the Clinton administration. “My fear is that the speculators are going to break it. They’re going to try to break up the system.”
‘A Pool Within the Pool’
In the last few years, Colorado has been debating a water policy approach that has further piqued the interest of private investors: paying farmers not to use the river at all.
Demand management, as the policy is known, is an attempt to solve the so-called wrong places problem and free up water from agriculture and reroute it to urban uses and conservation.
“The idea is, if you pay the farmers enough, they’ll go away,” said Brad Udall, a water and climate researcher at Colorado State University whose family have been lawmakers in the region for 60 years…
It’s not necessarily a new concept — in parts of Southern California, farmers have been paid for more than a decade to fallow land. Nor is it official policy yet. But Mr. Eklund would like it to be.
As Colorado’s water commissioner, he piloted a demand-management program and was known for crisscrossing Colorado’s back roads to convince skeptical farmers of the benefits of the approach. Later, as the state’s negotiator on the Colorado River, he helped make it an official goal of the compact states.
Mr. Eklund secured an “account” in Lake Powell. In theory, water saved by demand management could flow to the account, often called “a pool within the pool,” and be drawn upon if the current drought continues to realize worst-case scenarios.
However, the same water could also flow where water often flows: toward the highest bidder. WAM and other investors could theoretically create their own reservoir “accounts” and let the water sit until its value was maximized.
Andy Mueller, general manager of the Colorado River District, is skeptical. “They’d have to have a storage account of their own in a federal reservoir, and from my perspective that’s a nonstarter,” Mr. Mueller said. “Right now, we have legal and political mechanisms in place to prevent that from happening.”
He added, though, that the pressure of the drought could shift the terrain. “Is that something that can change? Yeah. And crisis drives change.”
The proponents of water markets say they are not in it just for the money. They believe that the West has an outdated and overregulated system governing access to water, which has encouraged the cultivation of crops in the desert.
“Agriculture all over the West required the development of irrigation infrastructure, such as dams and ditches,” Mr. Libecap said. “Often, the best land in the West is not along rivers, so you needed to move water.”
The system worked as long as there was enough to go around, said Mr. Libecap, who recently advised the State of Colorado on its growing water problems…
Mr. Mueller believes that the demand management pilot program triggered a land rush in rural western Colorado, with investors snapping up farms and flipping their water rights.
WAM has become one of the largest landholders in the Grand Valley, a high-mountain desert on the Western Slope of the Rockies, 250 miles west of Denver. But Mr. Eklund denies that the firm is flipping water rights…
Of course, not everyone has been displeased by the arrival of hedge funds reportedly paying millions in cash for old farms. Marc Catlin, a third-generation farmer who represents western Colorado in the General Assembly, said, “A farmer’s property is their 401(k).”
The Enron Fear
Where water investors have historically gotten involved in markets is through agriculture, with mixed results.
In 2015, California got just 5 percent of its average annual snowpack, the lowest in 500 years. Utilities, which in previous dry years bought water from farmers, found they could no longer afford it. The price had risen tenfold in a matter of months.
It wasn’t just the drought: California’s crops had shifted from low-value seasonal vegetables like lettuce and bell peppers to permanent non-staples, like almonds, that were so valuable that it was no longer economical for farmers to sell water to cities, even as prices spiked.
Mr. Kightlinger, of the Metropolitan Water District of Southern California, traces the recent private-investor interest in water to the 2015 crisis. “When you have pistachio and almond farmers willing to pay 10 times the average price, people sit up and say, ‘How can I own some of this?’” he said…
California’s agricultural water markets — a mosaic of online exchanges connecting farmers and water brokers — are considered a potential model for the West: fast, flexible and responsive to extreme weather. In September, Nasdaq and CME Group, the world’s largest derivatives marketplace, announced plans to open a futures market for California water, joining it with commodities like Brent crude oil and soybeans.
The market in the Colorado-Big Thompson Project is also nimble and responsive. An engineering marvel from the heyday of federal water construction, the project is a vast network or reservoirs filled by a tunnel that pipes water from the Colorado River 13 miles under the Continental Divide. The high-tech market there services Denver and other cities, fueling development in some of the fastest-growing housing markets in the country. In the last 10 years, the price of water there has gone up more than eightfold.
In Australia, however, water markets have had unintended consequences. Valued at $2 billion after 14 years in existence, Australia’s markets primarily facilitate trades in agricultural areas. When started, they were hailed as a fast, flexible way of redistributing water on the driest inhabited continent, with little regulation attached.
“We went harder and faster than anyone and let the market rip,” said Stuart Kells, a professor at La Trobe Business School in Melbourne. “We let anyone come play.”
This led to domination by professional investors with no ownership of farmland, Mr. Kells said. As a result, “water has turned into a financialized product like what happened to energy in the late 1990s,” he said.
Last year, Australia’s devastating wildfires and drought spiked water prices. Subsequently, the government’s antitrust department started an inquiry. Though it stopped short of calling for a shutdown, an interim report last summer recommended comprehensive changes in water markets, citing inadequate regulation and market exploitation by professional traders.
“Here water is very scarce, and in periods of shortage traders essentially cheer on the drought,” Mr. Kells said. “The markets have become a paradise for arbitrage.” He compared the dynamic to “California in the 1990s, where fires and outages were beneficial for traders because of price spikes and you saw Enron traders cheering on fires.”
Australia has also seen the advent of a market in complex financial products, such as derivatives, based on water.
“What has happened in Australia should be a cautionary tale for America,” Mr. Kells said. “The way the markets were set up left them open to being gamed.”

The warming climate is intensifying drought, contributing to fires and drying out the river’s headwaters, sending consequences cascading downstream.
ROCKY MOUNTAIN NATIONAL PARK, Colorado — Beside a river that winds through a mountain valley, the charred trunks of pine trees lie toppled on the blackened ground, covered in a thin layer of fresh snow.
Weeks after flames ripped through this alpine forest, a smoky odor still lingers in the air.
The fire, called the East Troublesome, burned later into the fall than what once was normal. It cut across Rocky Mountain National Park, racing up and over the Continental Divide. It raged in the headwaters of the Colorado River, reducing thick forests to ashes and scorching the ground along the river’s banks.
The fires in Colorado spread ferociously through the summer and fall of 2020 after months of extreme heat that worsened the severe drought.
As smoke billowed over the headwaters, the wildfires raised warning signs of how profoundly climate change is altering the watershed, and how the symptoms of heat-driven drying are cascading down the heavily used river — with stark implications for the entire region, from Colorado’s ranchland pastures to the suburbs of Phoenix…
Over the past year, the relentless hot, dry months from the spring to the first snows left the soil parched. The amount of runoff into streams and the river dropped far below average. With reservoirs sinking toward new lows, the risks of shortages are growing.
Much of the river’s flow begins as snow and rainfall in the territory of the Colorado River Water Conservation District, which includes 15 counties on Colorado’s West Slope. Andy Mueller, the district’s general manager, said the extreme conditions over the past year offer a preview of what the region should prepare for in the future.
“Climate change is drying out the headwaters,” Mueller said. “And everybody in the Colorado River Basin needs to be concerned.”
Mueller saw the effects while backpacking in Colorado’s Holy Cross Wilderness in the summer with his 19-year-old daughter. Above the tree line, at an elevation of 12,000 feet, they expected to see mushy green tundra. Instead, they found the ground was bone dry…
People who focus on the river have widely acknowledged the need to adjust to a shrinking system with less water to go around.
Many suggest solutions can be achieved through collaborative efforts — often with money changing hands in exchange for water — while working within the existing rules. Others say solutions shouldn’t fall on the backs of farming communities by taking away water that fuels their economies. Some people argue the river seems headed for a crash and its rules need to be fundamentally reimagined…
The deals between the seven states are designed to temporarily lower the odds of Lake Mead and Lake Powell dropping to critical lows over the next five years. The states’ representatives have yet to wade into the details of negotiations on what shortage-sharing rules will look like after 2026, when the current agreements expire.
Still unresolved are difficult questions about how to deal with the shortfall over the long term.
What’s increasingly clear is that the status-quo methods of managing the river are on a collision course with worsening scarcity, and that eventually something will have to give…
Watershed ‘thirstier’ with heat
Last winter, after a dry year, the Rocky Mountains were blanketed with a snowpack that was slightly above average. Then came extremely hot and dry conditions, which shrank the amount of runoff and flows into tributaries and again baked the soils dry.
[Andy] Mueller said the change occurred abruptly at the end of the snow season in the spring…
With the heat, some of the snow didn’t melt but instead evaporated directly into the air, which scientists call sublimation — something that has been happening more over the past two decades. The flows in streams dropped over the next few months, and then August brought record heat, which dried out the headwaters and fueled the fires through the fall…
In a 2018 study, scientists found that about half the trend of decreasing runoff in the Upper Colorado River Basin since 2000 was the result of unprecedented warming. In other research, scientists estimated the river is so sensitive to warming that it could lose roughly one-fourth of its flow by 2050 as temperatures continue to rise…
“A warmer atmosphere is a thirstier atmosphere, and we’re seeing less runoff bang for our precipitation buck,” said Jeff Lukas, an independent climate researcher in Colorado. “We’ll still have wetter and drier years, but the baseline is very likely to be shifting downward, as it has in the last 20 years.”
And when extreme heat comes, it leaves less water running in tributaries and also translates into drier forests, leading to increased fire risk.
The soils were so dry over the past year that they soaked up moisture, contributing to below-average stream flows, said Megan Holcomb, a senior climate change specialist with the Colorado Water Conservation Board.
“You can think of it as like the dry sponge that you haven’t wetted in forever,” Holcomb said. “That kind of soil moisture deficit is not something that you rebound from immediately.”
After the hot spring came a dry summer. The lack of monsoon rains compounded the drought. And then came August, Holcomb said, when a map of record-hot temperatures hugged the Colorado River Basin like a “massive red handprint.”
In areas of western Colorado that drain into the river, it was the hottest and driest August on record, breaking the previous temperature record by 2 degrees F, said Russ Schumacher, Colorado’s state climatologist and director of the Colorado Climate Center.
The state usually gets its largest wildfires in June and July. But with the severe drought, the fires burned through August, and then exploded in October with unprecedented speed and intensity. The ultradry conditions, together with high winds, contributed to the three largest wildfires in Colorado history, which together devoured more than half a million acres.
In the future, rising temperatures will lead to more of these scorching summers.

Scenes of the CalWood Oct. 17, 2020 (Jivan West/CU Independent)
Abby Burk of the conservation group Audubon Rockies noticed how low the river was in the summer when she went paddling in her kayak. In parts where the river was full and muddy a year earlier, she found bars of gravel. Where there once were channels to paddle through, she encountered dead-end lagoons.
In November, when Burk drove through the headwaters near the smoldering fires, she snapped photos of the hills and mountains, still golden-brown beneath a dusting of snow.
When the soil is so parched, it will always “take the first drink” before water reaches the streams, Burk said. “We need a lot more snow for many years to come to really replenish the soil moisture deficits that we’re seeing now.”
The fire scars will also bring challenges come spring, she said, when melting snow will send runoff carrying ash, debris and sediment into streams, potentially creating complications for water systems.
Burk said she’s hoping there will be a slow melt so the runoff comes gradually, without “bringing down the mountain into the river.”
A rancher looks to adapt
Paul Bruchez raises cattle on his family’s ranch in the headwaters near the town of Kremmling, where the Colorado River winds through pastures…
Bruchez has been involved in discussions about the river as a member of the Colorado Basin Roundtable. And while he’s heard many people voice alarm about the watershed lately, Bruchez said he and other neighboring ranchers have been talking about the need to adapt to a river with less water since 2002, when severe drought came.
The flows dropped so low then that even ranchers with the longest-standing water rights, known as senior rights, couldn’t get it to their fields.
“Within this river basin, we have seen a change over time of the quantity and volume of water that is available. And in that same time, we’ve seen a growth of population that relies on it,” Bruchez said. “We knew this in 2002 when we hit that drought, that if we didn’t change how we operated, we weren’t going to survive.”
Since then, Bruchez and other ranchers have been talking about ideas for adapting…
The closer the region gets to a scenario of curtailing water allotments, Bruchez said, the more investors and representatives of cities and towns are going to be contemplating ways of securing water from elsewhere.
For people in agriculture, he said, “we need to be at the table or we’re going to be on the menu.”
‘It affects everybody’
One of the main tributaries that feeds the Colorado is the Gunnison River, which like the mainstem has shrunk during the heat-amplified drought. Along the Gunnison, cattle ranchers got less water last year and their pastures produced less hay.
The river’s low flows also forced an early end to the river rafting season on Labor Day weekend. After that, releases from a dam had to be cut back and the Gunnison was left much shallower than usual, with rocks protruding in stretches where boats would normally be drifting until the end of September.
The river has dropped to some of its lowest levels in years, said Sonja Chavez, general manager of the Upper Gunnison River Water Conservancy District.
The effects are visible at Blue Mesa Reservoir, one of the state’s largest, which has declined to less than half its full capacity.
Visiting the lake, Chavez walked on sandy ground that used to sit underwater.
Looking across the inlet where the river pours into the lake, she pointed to a gray line on the rock showing the high-water mark. During spring runoff, she said, the river in this channel can reach about 20 feet higher. But with the soil so parched, its level dropped.
“When we are dry in the Upper Gunnison Basin, it affects everybody downstream of us,” Chavez said. And the swings between high and low flows, she said, have made it difficult to plan how to operate the reservoirs…

In the Gunnison Valley, a local climate action group meets to talk about potential solutions. Some conversations have focused on how to manage forests that have grown thick with vegetation over the past century as federal agencies have focused mostly on putting out fires.
While the forests have grown thicker, warmer temperatures have enabled beetles to flourish, littering the mountains with dead trees.
Chavez and others want to prioritize efforts to make the forests healthier and more fire-resilient by thinning the trees through logging, mechanical treatments or controlled burns, which they say would make the whole watershed healthier. She said the federal government needs to be more involved and the region needs funding for these projects.
“Our big push this year is to do some watershed management planning and work with the Forest Service to identify zones of concern, or areas that we can treat,” Chavez said. “We’re worried if we had a big fire what would happen.”
Alongside those efforts, water managers are discussing ways of dialing down water usage…
Ranchers, farmers consider using less
One lifelong rancher who had a smaller-than-usual hay crop was Bill Trampe, who has worked on water issues for years as a board member of the Colorado River District.
His cattle graze on meadows near Gunnison where the grasses survive year after year. He was short of water to irrigate after mid-June, which left the pastures parched.
Over the past two decades, only a few years brought good snowpack, he said, and ranchers have repeatedly had to weather the financial hits of years when they must buy hay for their cattle…
‘We need to set the terms’
In other parts of the river basin, some representatives of agricultural water agencies are worried about the potential consequences of paying farmers to leave land dry.
One such voice is J.B. Hamby, a newly elected board member of California’s Imperial Irrigation District, who said he’s concerned that while cities and sprawling suburbs continue to grow rapidly, agricultural communities are increasingly at risk. He said people in cities need to realize there is a priority system that shouldn’t be changed…
Arizona gets nearly 40% of its water from the Colorado River. Much of it flows in the Central Arizona Project Canal, which cuts across the desert from Lake Havasu to Phoenix and Tucson.
In 2020, Arizona and Nevada took less water from the river under the drought agreement among Lower Basin states, and in 2021 they will again leave some of their water in Lake Mead. The latest projections show Mead could fall below a key threshold by summer, which would trigger a shortage declaration and larger cutbacks in 2022…
Now, with less water flowing to farms, the amount of runoff into the Salton Sea has shrunk, leaving growing stretches of exposed lakebed that spew dust into the air. The dust is contributing to some of the worst air pollution in the country, and many children suffer from asthma.
Hamby said the Imperial Valley would have been better off without the water transfer deal. Looking at the proposed approach in Colorado, Hamby said, it seems to replicate what occurred in Imperial.
“When you tie money to water, you get users who become addicted to the money and don’t actually in the end start to want to farm anymore,” Hamby said. “That is really corrosive to the long-term survival, much less thriving, of rural communities when people get more hooked on money rather than the way of life and putting the water on the land.”
He argued that such an approach would be “subverting the whole priority system” and enabling cities to avoid taking cuts themselves…
‘Are we doing enough?’
At his ranch by the river, Bruchez said he wants to be on “the preventative side,” getting ahead of the looming problems instead of reacting. And that includes studying and promoting conservation, he said, because the bottom line is “we just all have to figure out how to use less water.”
In early 2019, Bruchez began talking with Perry Cabot, a researcher from Colorado State University, about a project that would help provide data on crop water use, impacts of reduced irrigation and strategies for conserving water.
Cabot gave a presentation to the Colorado Basin Roundtable, and members supported the idea of a study. The project began in 2020 with about $900,000 in funding, including support from the Colorado Water Conservation Board and groups including Trout Unlimited and American Rivers.
A group of nine ranchers participated and were paid for leaving some fields dry or partially dry, Bruchez said. More than 900 acres weren’t irrigated for the entire year, and about 200 acres were “deficit irrigated,” meaning they received less water.
Bruchez’s ranch totals about 6,000 acres. He participated on about 41 acres, where he stopped irrigating on June 15 and didn’t water the rest of the year.
“My end goal is to understand the impacts of water conservation for agriculture so that if and when there are programs to participate, agriculture is doing it based on science,” Bruchez said…
Paul Bruchez said he’s seen that when people talk about solutions, they often seem to draw boxes around different approaches like demand management, water conservation, climate change and forest management, but he thinks they’re all quite connected.
“It’s all the same conversation,” Bruchez said. “To me, the question just comes down to, are we doing enough, quick enough?”
“It’s that water that is provided by the Colorado River that ties us all together,” Mueller said. “And truly, when we recognize the importance of the Colorado River and how it ties us together, that’s when we succeed as a society.”

As its trial date in water court approaches, hundreds of pages of depositions obtained by Aspen Journalism reveal state engineers’ sticking points regarding a proposed reservoir project they oppose in northwest Colorado.
Over a few days in November, state attorneys subpoenaed and interviewed several expert witnesses and the Rio Blanco Water Conservancy District manager in the White River storage-project case, also known as the Wolf Creek project. Their questions centered on the town of Rangely’s water needs and on whether water is needed for irrigation.
The documents, obtained through a Colorado Open Records Act request, also underscore the extent to which fear of a compact call is shaping this proposed dam and reservoir project between Meeker and Rangely.
The Rangely-based Rio Blanco Water Conservancy District is applying for a conditional water-storage right to build a 66,720-acre-foot, off-channel reservoir using water from the White River to be stored in the Wolf Creek drainage, behind a dam 110 feet tall and 3,800 feet long. It would involve pumping water uphill from the river into the reservoir.
There also is an option for a 72,720-acre-foot on-channel reservoir, although this scale of project is now rare in Colorado. Rio Blanco has said they prefer the off-channel option.
For more than five years, top state water engineers have repeatedly said the project is speculative because Rio Blanco has not proven a need for water above its current supply.
Despite Rio Blanco reducing its claim for water by more than 23,000 acre-feet from its initial proposal of 90,000 acre-feet, state engineers still say the water-right application should be denied in its entirety. After failing to reach a settlement, the case is scheduled for a 10-day trial in January. Division 6 Engineer Erin Light and top state engineers Kevin Rein and Tracy Kosloff are the sole opposers in this case.
Rio Blanco already operates Kenney Reservoir, just east of Rangely on the White River. But it is silting in at an average of 300 acre-feet per year and is nearing the end of its useful life, according to court documents.
A main point of contention between Rio Blanco and state engineers is whether there will be an increased need for irrigation water in the future. Rio Blanco claims it needs 7,000 acre-feet per year for irrigation.
During the depositions, state attorneys questioned Rio Blanco manager Alden Vanden Brink about the need for irrigation water. He claimed there is a local boom in agriculture and that there is high-value farmland that is not being irrigated simply because of a lack of water. Vanden Brink said happiness for residents on the lower White River will increase with access to irrigation water from the proposed reservoir, adding that if irrigation water is made available, demand for it will increase.
“It will make water available in the lower White River so that people can increase their quality of life and have a garden, you can have a few pigs,” Vanden Brink’s deposition reads. “It’s just going to be improvement all the way around.”
But details were sketchy on what specific lands would be irrigated and the district’s plan to get water from the reservoir to irrigators. State engineers, in a subsequent trial brief, say that just because there are lands that might benefit from irrigation doesn’t mean there will be future increased demand. If you build it, they won’t necessarily come.
“Instead, the premise that there will be a demand for water if the water right is granted is exactly the sort of ‘self-fulfilling prophecy of growth’ prohibited under Colorado’s anti-speculation doctrine,” the state’s trial brief reads.
Engineers also say Rio Blanco has not identified how the reservoir, situated low in the White River basin, would serve the majority of irrigated acres located upstream.
“For instance, Rio Blanco has not identified any pipeline construction or other water project works that could run water up to these other locations,” the state trial brief reads.
Rangely’s water needs
Rio Blanco and the state also disagree about the amount of water needed for Rangely, a high-desert town of about 2,300 people near the Utah border. Rangely takes its municipal water from the White River.
In their depositions, Vanden Brink and Gary Thompson, an expert witness and engineer with W.W. Wheeler and Associates, refer to “cow water” as the source of Rangely’s water issues.
According to Vanden Brink, who also is the town’s former utilities supervisor, when flows in the White River drop to around 100 cubic feet per second, water quality becomes impaired. That can include increased algae growth, decreased dissolved oxygen, increased alkalinity and increased mineral contaminants, which require more treatment, he said.
“If you want to look at that water and how you can take that water and make it potable, forgive me, but it looks worse than cow water,” Vanden Brink said in his deposition. “I know if I was a cow, I wouldn’t want to drink it. It’s pretty degraded; it’s pretty muddy, it’s bubbly, it’s gross. And there’s a reason Rangely’s got the extensive treatment that it does.”
In an April letter to Rio Blanco, Town Manager Lisa Piering and Utilities Director Don Reed said Rangely would commit to contract for at least 2,000 acre-feet of storage for municipal use after the reservoir is built. According to expert reports, Rangely’s current demands are 784 acre-feet per year.
Project proponents say that increased flows from reservoir releases will dilute contaminants and improve water quality at the town’s intake.
But this argument doesn’t work for state engineers, who say that the water Rio Blanco says Rangely needs is not based on projected population growth and that Rio Blanco has not analyzed whether the town’s existing water supplies would be sufficient to meet future demands.
“Rio Blanco at trial may attempt to offer evidence regarding needs based on water quality, but Rio Blanco has not disclosed any evidence quantifying the amount of water Rangely would need for that purpose,” the trial brief reads.
Colorado River Compact influence
Depositions and water court documents reveal how water managers’ and experts’ fear — and expectation — of a compact call could influence the project proposal.
According to the 1922 Colorado River Compact, the upper-basin states (Colorado, Utah, New Mexico and Wyoming) must deliver 7.5 million acre-feet a year to Lake Powell for use by the lower-basin states (Arizona, California and Nevada). If the upper basin doesn’t make this delivery, the lower basin can “call” for its water, triggering involuntary cutbacks in water use for the upper basin.
Water managers and policymakers admit that no one knows how it would play out just yet, but risk of this hypothetical scenario becoming reality is increasing as drought and rising temperatures — both fueled by climate change — decrease flows into Lake Powell.
Water managers are especially worried that those with junior water rights, meaning those later than 1922, will be the first to be curtailed. Senior water rights that existed prior to the compact are generally thought to be exempt from compact curtailment.
Many water users in the White River basin, including the towns of Rangely and Meeker, have water rights that are junior to the compact, meaning the users could bear the brunt of involuntary cutbacks in the event of a compact call.
Rio Blanco is proposing that 11,887 acre-feet per year be stored as “augmentation,” or insurance, in case of a compact call. Releasing this replacement water stored in the proposed reservoir to meet these compact obligations would allow other water uses in the district to continue and avoid the mandatory cutbacks in the event of a compact call.
According to Rio Blanco’s trial brief, “there is significant risk of a compact curtailment in the next 25 years that could negatively impact 45% of the water used in the district.”
In his deposition in response to questions from Rio Blanco attorney Alan E. Curtis, Thompson said drought scenarios will get worse in the future, the White River will be more strictly administered and a compact call is likely to occur.
“Things are — in my opinion — drought conditions are increasingly pervasive,” he said.
But state engineers say that augmentation use in the event of a compact call is not a beneficial use under Colorado water law and is inherently speculative. Compact compliance and curtailment are issues to be sorted out by the Upper Colorado River Commission and the state engineer, not individual water users or conservancy districts, they say. The state of Colorado is currently exploring a concept called demand management, which could pay water users to use less water in an effort to boost levels in Lake Powell.
According to their trial brief, state engineers say that while the desire to plan for compact administration is understandable, “the significant uncertainties involved in future compliance under the Colorado River Compact mean that Rio Blanco cannot show a specific plan to control a specific quantity of water for augmentation in the event of compact curtailment.”
The trial is scheduled to begin Jan. 4 in Routt County District Court in Steamboat Springs. Among the witnesses that Rio Blanco plans to call are Colorado River Water Conservation District Manager Andy Mueller, Colorado Water Conservation Board Chief Operating Officer Anna Mauss and Rio Blanco County Commissioner Gary Moyer.
Aspen Journalism is a local, nonprofit, investigative news organization covering water and rivers in collaboration with The Aspen Times and other Swift Communications newspapers. This story ran in the Dec. 26 edition of The Aspen Times and the Vail Daily, and the Dec. 28 edition of Steamboat Pilot & Today.
On Nov. 30 Governor Jared Polis sent a “memorandum of drought emergency” to executive directors of state government departments. The memo marks the beginning of phase 3 “full plan activation” of the state’s Drought Mitigation and Response Plan.
The memo said “deep and persistent drought conditions” had covered the state for 15 weeks, noting that this level of drought had not been observed since 2013. It also activated the “Municipal Water Impact Task Force,” chaired by members of the Colorado Water Conservation Board and the Department of Local Affairs.
The memo states: “The initial objective of the Task Force is for water suppliers to coordinate with each other and the state going into winter to prepare for anticipated drought-related challenges and opportunities in 2021.”
“So it’s telling you to get planning for a drought, which is what your water conservancy districts, Yellow Jacket and the Rio Blanco Water Conservancy districts are attempting to do” said Alden Vanden Brink, District Manager for the Rio Blanco Water Conservancy District.
During a Dec. 14 Board of County Commissioners work session, he spoke about the Governor’s memo and its implications for the basin. “I’ve been following up on this quite a bit trying to make sure they understand that there is no drought contingency within our White River basin,” he said.
By drought contingency, Vanden Brink was referring to storage, of which he said there is very little in the basin. “You’re looking at just a couple of days worth of water, literally,” said Vanden Brink, later adding “we have a real problem with the lack of storage in our basin, a real problem, and it makes us extremely vulnerable.”
That vulnerability, though not exactly new to the basin, is growing more urgent. Colorado’s record drought in 2020 was just the beginning of a more long term trend, according to leading climatologists and groups like the National Oceanic and Atmospheric Administration (NOAA)…
That planning includes preparations for an upcoming water court lawsuit set to begin in the first week of January. “It’s to get a conditional water right to construct a reservoir for drought contingency within the White River basin.” said Vanden Brink, referring to the Wolf Creek Reservoir, also known as the White River Storage project. The project would store between 66,000 and 73,000 acre feet of water, depending on the exact location.
In an expert report submitted earlier this year, state engineers contested that Rio Blanco had failed to identify the need for that much water. Ultimately that disagreement is what prompted the lawsuit between the Rio Blanco Water Conservancy District and the State’s Division of Water Resources.
Adding to his message of urgency, Vanden Brink talked about proposed “demand management” strategies which are likely to become more prevalent in coming years. “What they’re looking at doing is paying a rancher to idle his field for a given period of time, and allow that water to flow by,” said Vanden Brink, noting that the development of those strategies was a changing dynamic. Although he didn’t speak negatively about the concept in general, he was concerned about its potential impact in the region. “Not allowing that water to go be used for flood irrigation….flood irrigation is what recharges our groundwater aquifer. That’s taking away from that groundwater aquifer what little storage we have, which is the aquifer” said Vanden Brink.
He argues that given the lack of existing storage, and thus lack of drought contingency in the basin, the Governor’s memorandum of drought emergency provides more legitimacy to Rio Blanco’s proposed reservoir project.
FromColoradoPolitics.com (Marianne Goodland) via The Colorado Springs Gazette:
The week of Dec. 14, the seven states that are part of the Colorado River Compact began the first step for renegotiating guidelines that will decide how much water the three lower basin states and Mexico will get from Lake Mead, on the Arizona-Nevada border, and from Mead’s source, the Colorado River.
The guidelines are interim, signed in April 2007, and are due to expire in 2026. Among the most significant, the guidelines provide long-term stable management of the river and also determine the circumstances under which the Interior secretary could reduce the annual amount of water available from Lake Mead to the Colorado River lower basin states. The guidelines also are a way for the basin states to avoid litigation, part of what prompted the 2007 interim guidelines.
The seven states that make up the Colorado River Compact, and which will negotiate those guidelines, are divided into upper basin states (Colorado, Wyoming, Utah and New Mexico) and lower basin states (Arizona, Nevada and California). Mexico is also part of the lower basin water allotment, as well. About 40 million people across the seven states rely on the Colorado River for water.
Colorado, Utah, Arizona and New Mexico are dealing with extreme drought conditions, according to the U.S. Drought Monitor.
What that means for the river heading into in the future, said John Fleck, a former journalist and author and now with the University of New Mexico’s Water Resources Program, is water levels in Lake Mead could drop to 1,060 feet by 2022. That’s 15 feet below what triggers “the next tier of mandatory Lower Basin water use cuts under the river’s 2007 interim guidelines and the supplemental drought contingency plan” signed last year…
Last week, the seven states signed a joint letter to Trump administration Interior Secretary David Bernhardt and Bureau of Reclamation Commissioner Brenda Burman requesting technical support from the federal agency, as the states move forward with negotiations. The states are setting up a working group to look at modeling for the management and operations of Mead and Lake Powell, which is the water “bank” on the Colorado River for the upper basin states…
[Rebecca] Mitchell said she thinks “everything is on the table as we look toward the future.” What’s in the final report — or not — “doesn’t mean we can’t deal with bigger issues outside of the guidelines.”
That’s also where the Biden administration, and his Interior nominee, U.S. Rep. Deb Haaland, D-New Mexico, could make a difference. One of the signs from Biden toward the Colorado River is his appointment of Tanya Trujillo of New Mexico to the Department of the Interior’s transition team. Trujillo is vice chairwoman of the New Mexico Interstate Stream Commission and lower basin project director for the Colorado River Sustainability Campaign. A water lawyer, Trujillo has experience working in Interior on water issues.
“We’re hoping (the new administration) will foster negotiations that are rooted in science and create a framework that recognizes how climate change is affecting and will continue to affect the basin,” Kim Mitchell, a senior water policy adviser with Boulder-based Western Resource Advocates, told BloombergLaw.com in November.
Officials from all seven states in the watershed sent a letter State letter to USBR re: Colorado River 2026 guidelines.[/caption] this week to Interior Department secretary David Bernhardt, letting the federal government know they’re ready to start hammering out details of operating guidelines for the biggest reservoirs in the country.
Dry conditions made worse from climate change have hit Lakes Mead and Powell hard during the last two decades, leaving them well below capacity.
But as those talks begin, long-standing tensions remain.
“The states noted in that correspondence the importance of engaging with water users, tribes, NGOs and Mexico as those discussions progress,” said John Entsminger, president of the Colorado River Water Users Association and general manager of the Southern Nevada Water Authority.
Tribes, environmentalists and recreation advocates have routinely been kept out of past negotiations, and say they’ll be pushing for more transparency in crafting the new rules…
“Greater inclusion earlier in the processes, will likely lead to more creative solutions, with more buy-in from the affected parties,” said Bureau of Reclamation commissioner Brenda Burman. The agency oversees water infrastructure in the West…
Current guidelines put in place in 2007 expire in 2026.
FromThe Associated Press (Felicia Fonseca) via U.S. News & World Report:
A set of guidelines for managing the Colorado River helped several states through a dry spell, but it’s not enough to keep key reservoirs in the American West from plummeting amid persistent drought and climate change, according to a U.S. report released Friday…
The report by the U.S. Bureau of Reclamation found that the guidelines provided stability, along with other agreements among the states and with Mexico, but they won’t be enough to sustain a region that’s getting warmer and drier and has demanded more from the Colorado River.
The guidelines and an overlapping drought contingency plan expire in 2026. Officials in Wyoming, Utah, Colorado, New Mexico, Arizona, California and Nevada told the Interior Department on Thursday that they have started talking about what comes next…
The Bureau of Reclamation was tasked with reviewing the effectiveness of the 2007 guidelines before year’s end to help with a baseline for the new negotiations. The guidelines spelled out the operations of the nation’s two largest manmade lakes — Lake Powell along the Arizona-Utah border and Lake Mead along the Arizona-Nevada border — outlining what happens when the river can’t supply the water that states were promised in the 1920s.
The guidelines allow water to be stored in Lake Mead, the reservoir created by the Hoover Dam. They set marks for the lake that would trigger water cuts to Nevada and Arizona. California and Mexico have been looped in on possible cuts in other plans.
The guidelines were meant to be flexible and encourage consensus among states, rather than the federal government dictating management of the river, and to avoid litigation because states were required to consult with each other before suing…
In comments before the report was finalized, Native American tribes said they largely were left out of the discussions that led to the guidelines and want a bigger role in the next round of talks, with recognition of their sovereign status. They hold the rights to 3.4 million acre-feet of water annually in the Colorado River basin.
Not all tribes, including the Navajo Nation and Hopi Tribe in northwestern Arizona, have secured the legal right to the water they claim in the basin.
Burman said the Bureau of Reclamation, states, tribes and others will focus in the weeks ahead on creating timelines for the negotiations…
When the 2007 guidelines took effect, Lake Powell and Lake Mead together were about half full. Conservation, delayed water deliveries, a balancing act and other measures have kept them hovering at that level.
States, tribes, cities and other water users are expected to use the Bureau of Reclamation report as a resource for deciding what will replace the guidelines.
Here’s the release from Reclamation (Patti Aaron and Linda Friar):
The Bureau of Reclamation today released a report intended to bring partners, stakeholders and the public to a common understanding of the effectiveness of the 2007 Colorado River Interim Guidelines for Lower Basin Shortages and Coordinated Operations for Lake Powell and Lake Mead. The technical report documents conservation efforts and operations on the Colorado River since 2007 and provides an essential reference to inform future operations.
“The report presents a thorough review of operations and highlights that we have experienced historic collaboration among states, tribes, water users, non-governmental organizations and the international community in addressing issues affecting one of America’s most important rivers,” said Commissioner Brenda Burman. “Forty million people across seven states and Mexico depend on the Colorado River for life and livelihood, so it’s critical that our actions protect this resource now and into the future. Today’s report highlights both the historic steps taken in the basin, as well as the need for continued progress to meet the growing challenges in the years ahead.”
The report concluded:
– The 2007 Interim Guidelines were largely effective as measured against both their stated purpose and common themes as provided in the 2007 Record of Decision.
– Increasing severity of the drought necessitated additional action to reduce the risk of reaching critically low elevations in Lakes Powell and Mead.
Experience over the past 12 years provides important considerations:
– enhanced flexibilities and transparency for water users
– expanded participation in conservation and Basin-wide programs
– increased consideration of the linkage that occurs through coordinated reservoir operations, particularly with respect to the inherent uncertainties in model projections used to set operating conditions
– demonstrated need for more robust measures to protect reservoir levels
Here’s the release from the Upper Colorado River Commission (Rebecca Mitchell):
Colorado joined Arizona, California, Nevada, New Mexico, Utah, and Wyoming to begin preliminary discussions regarding the upcoming negotiations of the Colorado River Basin operational guidelines.
Governors’ representatives from each of the Colorado River Basin States signed a joint letter to Secretary of the Interior David Bernhardt and Bureau of Reclamation Commissioner Brenda Burman requesting technical support from the federal agency as the states move forward with these discussions. Colorado’s Upper Colorado River Commissioner Rebecca Mitchell signed the letter on behalf of Colorado.
“Colorado will continue leading the effort with the other Colorado River Basin States on negotiating the next set of operational guidelines to ensure western water is managed effectively and sustainably, and during the process will engage with all groups invested in the outcome including water users, the Tribal Nations, Mexico, and non-governmental organizations,” said Commissioner Mitchell. “As we continue to face climate change impacts, including persistent drought, working together to find solutions to our water challenges is more important than ever.”

Western Water Spotlight: draft assessment of 2007 interim guidelines expected to provide a guide as talks begin on new river operating rules for the iconic southwestern river
Twenty years ago, the Colorado River Basin’s hydrology began tumbling into a historically bad stretch. The weather turned persistently dry. Water levels in the system’s anchor reservoirs of Lake Powell and Lake Mead plummeted. A river system relied upon by nearly 40 million people, farms and ecosystems across the West was in trouble. And there was no guide on how to respond.
So key players across the Basin’s seven states, including California, came together in 2005 to attack the problem. The result was a set of Interim Guidelines adopted in 2007 that, according to a just-released assessment from the Bureau of Reclamation, mostly worked. Stressing flexibility instead of rigidity, the guidelines stabilized water deliveries in a drought-stressed system and prevented a dreaded shortage declaration by the federal government that would have forced water supply cuts.
Those guidelines, formally called “Interim Guidelines for Lower Basin Shortages and the Coordinated Operations for Lake Powell and Lake Mead,” are set to expire in 2026 As stakeholders in the Colorado River Basin — including water agencies, states, Native American tribes and nongovernmental organizations — prepare to renegotiate a new set of river operating guidelines, Reclamation’s assessment is expected to provide a guide for future negotiations.
“We find that the guidelines were largely effective,” said Carly Jerla, modeling and research group manager with the Bureau of Reclamation’s Lower Colorado River region and one of the report’s authors. However, the Interim Guidelines could not solve all of the challenges brought by what has become a two-decade-long drought in the Basin. Said Jerla: “We saw risk getting too high and needed additional assets.”
Preserving Lake Mead
With the guidelines as a foundation, those assets arrived in 2019 through drought contingency plans for the Upper and Lower Basin – voluntary reduction commitments that built a firewall against the likelihood of Lake Mead dropping to critically low levels.
Chris Harris, executive director of the Colorado River Board of California, said the guidelines achieved their objective, considering that the drought has essentially persisted since 2000. Even with the severity and longevity of the drought, the guidelines kept the two reservoirs at about 50 percent of capacity since 2007.
“To my mind that’s a pretty good marker that we were generally successful,” Harris said.
Reclamation’s review of the Interim Guidelines was released for public comment in October. It is expected to be finalized in December. After that, discussions are expected to begin to hammer out a new set of operating rules that would be ready to take effect when the existing guidelines expire in 2026.
Reclamation’s review, which was required under the guidelines, focused solely on how effectively the Interim Guidelines managed water shortages and storage in Lake Powell and Lake Mead. It did not include existing environmental management programs such as the Glen Canyon Dam Adaptive Management Program that are independent of the guidelines. The 2026 guidelines should take a broader view, said Matt Rice, director of American Rivers’ Colorado River Basin Program.
“Not just looking at the two big buckets [reservoirs], but how do we ensure the river is healthy and has water for its environmental needs,” he said.
“How do we ensure that communities are considered, certainly the tribes, and how do we evaluate additional future demands, projects like the Lake Powell pipeline (a proposed project to deliver Lake Powell water to Southern Utah).”
Ensuring Tribal Participation
Tribal water rights are a key consideration to future Colorado River water use. Ten federally recognized tribes in the Upper and Lower Basins have reserved water rights, including unresolved claims, to divert about 2.8 million acre-feet of water per year from the river and its tributaries, according to Reclamation’s 2018 Tribal Water Study. These tribes anticipate diverting their full water rights by 2040.
Reclamation’s review emphasizes the need for listening to all voices, most notably tribes. Tribal representatives were largely overlooked in the development of the 2007 Interim Guidelines and tribes want to make sure their voices are heard when the next set of operating rules are drawn up.
“We hope that the review will remind Reclamation of the importance that Indian tribes have played in the stewardship of the Colorado River and underscore the importance of meaningful and sustained participation of the Lower Basin tribes in any future guidelines development regarding management of the Colorado River,” Jon Huey, chair of the Yavapai-Apache Nation in Arizona, wrote in a letter to Reclamation.
Jerla said Reclamation recognizes how important it will be to include the tribes in future discussions.
“We definitely heard that loud and clear,” she said. “I think the critical role that tribes have played in the activities since the Guidelines … their desire to be more involved and more included, they will absolutely be a key part of efforts going forward, no question.”
Balancing Water Uses
There is inherent tension in balancing Colorado River water uses between the two basins. Part of the problem is users in the Lower Basin can use Lake Mead as a bank account, having water released downstream to them as they need it. Lake Powell, on the other hand, sits at the bottom of the Upper Basin’s drainage and water that flows into Powell is largely beyond reach of Upper Basin users.
“The guidelines have been partially successful in that they have achieved their principal objective of preventing Lower Basin shortage, as well as establishing a Lower Basin conservation mechanism and avoiding litigation in the Basin,” said Amy Haas, executive director of the Upper Colorado River Commission. “However, from the standpoint of the coordinated operations of Lakes Powell and Mead, a secondary objective of the Guidelines, they have come up short.”
Haas pointed out that between 2015 and 2019, Lake Powell was required to release 9 million acre-feet of water annually under the Guidelines, even with poor inflows into Powell and below-average hydrology in the Upper Basin watershed. That’s more than has historically been required.
“Meanwhile, Lake Mead elevations have not substantially increased under the Guidelines due in large part to overuse in the Lower Basin, also known as the structural deficit,” she said. “These issues must be addressed in the post-2026 operational criteria.”
Protecting the Colorado River
Drought wreaked havoc on the Colorado River Basin between 2000 and 2004, with record dryness that depleted the combined storage of Lake Powell and Lake Mead. Conditions worsened quickly. At the beginning of the 2000 water year, the review said, the combined storage in Lake Powell and Lake Mead was 55.7 million acre-feet. After the worst five-year period of inflow on record ended in 2005, that storage fell to 29.7 million acre-feet – a striking loss of nearly half of the water in the two anchor reservoirs.
Something new had to be done. The business-as-usual approach of determining drought conditions for the Basin on a yearly basis was not going to provide long-term stability or prevent conflict under such historic dryness.
“Failing to develop additional operational guidelines would make sustainable Colorado River management extremely difficult,” Reclamation’s review said.
The Interim Guidelines in 2007 opened the door for Lower Basin water users and Mexico to get creative about how water is managed and used. One example that grew out of the guidelines is Intentionally Created Surplus, allowing downstream parties to bank water in Lake Mead that they could draw upon later.
“One result of this new flexibility was that critical Lake Mead elevations could be protected through the conservation of this water in the lake,” said Tom Buschatzke, director of the Arizona Department of Water Resources. “The Basin states, meanwhile, continued to seek ways to protect reservoir levels and the health of the Colorado River system.”
Saving Intentionally Created Surplus water in Lake Mead turned out to be a critical drought response tool, said Reclamation’s Jerla, ensuring that the lake’s water level did not drop to where water users would be required to take cuts.
Reclamation’s review of the Interim Guidelines notes that there are other areas of interest beyond its scope that should be considered in future discussions, such as impacts of river operations to environmental, recreational and hydropower resources, and more meaningful engagement of Basin partners, stakeholders, tribes and states.
The review notes that since the Interim Guidelines were adopted, Reclamation has expanded its long-term modeling assumptions and worked to identify appropriate methods for analyzing uncertainty.
“Even though the true probability of any combination of conditions … cannot be assessed, a wider range of hydrology and demand assumptions and attention to those ranges … are useful for supporting a common understanding of system vulnerability,” the review says.
The Next Set of Guidelines
The 2007 Interim Guidelines have set the table for the next version of a Colorado River operations agreement. In retrospect, things have generally occurred as expected, Jerla said.
“In terms of where the reservoirs landed, what types of releases Powell made and how successful the Intentionally Created Surplus mechanism became, that is all within the range of what we were projecting,” Jerla said. “It’s informative to know that now and use that thinking about how risk influenced our decisions and how that translates into the next set of action levels.”
The Interim Guidelines instilled a degree of greater cooperation and innovation on the river and that has fostered partnerships, initiatives and actions that demonstrate what can be done in a Basin that is steadily getting drier.
“Those things have to continue,” Jerla said, adding that Reclamation’s review is one of many sources officials will consult as they draft the next set of guidelines.
Rice, with American Rivers, said he’s optimistic about the prospects of a broad group of stakeholders building the next set of Interim Guidelines.
“I am not suggesting that it’s going to be easy or straightforward by any means,” he said. “We certainly hope there will be greater participation from more stakeholders. The tribes are at the top of the list, but also nongovernmental organizations, which traditionally have not been part of these interbasin negotiations.”
The talks are likely to be frank and will explore thorny issues related to equitable water management.
Arriving at a satisfactory operational plan beyond 2026 means the Lower Basin’s structural deficit has to be addressed and balancing releases between Lake Powell and Lake Mead should be revisited to reflect actual hydrology, said Haas, with the Upper Colorado River Commission. “Also, the new guidelines should contain a mechanism whereby operations can be adapted and adjusted to meet changing conditions, something the current guidelines are not equipped to do.”
How the next set of river operating guidelines will take shape remains to be seen, but Reclamation’s review suggests the 2007 Interim Guidelines proved their worth in showing how water users can work together and think creatively, lessons that will be invaluable for the future.
The 2007 Interim Guidelines, the review said, “created the operational stability that became the platform for the collaborative decision-making that protected the Colorado River system from crisis.”
FromThe Grand Junction Daily Sentinel (Dennis Webb):
State water officials are hoping early next year to roll out a draft demand management proposal to help in evaluating the concept as a possible response to managing Colorado River water supplies in times of drought.
Creating a framework of what the program could look like isn’t meant to tie hands and say what the Colorado Water Conservation Board thinks it should look like, CWCB staff member Amy Ostdiek told the board in its meeting earlier this month. Rather, it’s aimed at giving everyone involved the ability to have something to respond to, with the hope of perhaps creating a better draft or a new concept, she said…
The CWCB, which sets state water policy, says demand management would involve temporary, voluntary and compensated reductions in consumptive use of Colorado River Basin water. This is expected to entail use reductions in municipal, agricultural and other uses, with agricultural cuts resulting from measures such as short-term fallowing of fields.
The idea is drawing particular scrutiny from entities such as the Western Slope’s Colorado River District due to concerns about potential economic impacts on agriculture-based communities. A recent study commissioned by a work group including the district found that the secondary economic impacts of paying western Colorado farmers to temporarily fallow fields could be similar to the secondary benefits from the spending of those payments. But it said the dollars from payment spending would flow to different businesses, perhaps shifting to larger towns and cities from smaller, ag-based towns.
Among other criteria for going forward, a demand management program would have to be found to be feasible by every Upper Basin state. This means looking at things such as availability of funding, whether a program would comply with state and federal laws, how it would be administered, etc.
The CWCB began evaluating the concept by establishing work groups involving experts and stakeholders from around the state looking at issues surrounding demand management.
With their input now in hand, the agency is taking the next step in investigating the concept. That will entail considering if it is achievable in terms of things such as funding, worthwhile when it comes to questions such as how much water would be stored, and ultimately advisable to pursue in Colorado.
CWCB plans to continue its evaluation in a public, collaborative way, involving water users, tribal entities, nongovernment organizations and other stakeholders in commenting on the draft proposal, Ostdiek said.
Becky Mitchell, the CWCB’s director, told the board at its meeting that fires and drought affected every Coloradan this year.
She said that with the climate changing and drought becoming more frequent and intense, it would be irresponsible for the CWCB not to look at every tool available to respond, including demand management.
New research reveals a creeping, permanent dryness expanding across the United States. It’s much more than “drought,” and researchers hope more accurate descriptions will spur critical action.
After nearly two decades of declining water flows into the Colorado River Basin, scientists have decided the word drought doesn’t cut it anymore. We need different terms, they say, to help people fully grasp what has happened and the long-term implications of climate change — not just in the Southwest, but across the country.
The term that’s caught the most attention lately is “megadrought.”
It’s not a new word, but it’s one that’s come sharply into focus in recent months, following a study published this April in the journal Science that found the North American Southwest has experienced an abnormally severe drought over the past two decades — its second driest stretch in 1,200 years.
Archaeological evidence has linked previous decades-long megadroughts to several historical societal collapses, including the Mayan civilization and Kublai Khan’s Yuan dynasty in China.
Let that sink in a minute if you need to.
The researchers, led by A. Park Williams of the Lamont-Doherty Earth Observatory of Columbia University, say this prolonged megadrought — which reached from Oregon and Idaho down to northern Mexico — would likely have been just a bad drought if not for climate change. The increase in temperatures from our burning of fossil fuels supercharged naturally varying conditions, creating one of the worst megadroughts in human history.
“The new study provided a nice basis to what many of us have felt now for a number of years,” says Brad Udall, a senior water and climate research scientist at Colorado State University, who was not involved in the research. “The basin has really entered a fundamentally different period than what we experienced during the 20th century.”
That may not come as a surprise to those who have noticed that the Colorado River’s biggest reservoirs, Lake Mead and Lake Powell, are now sitting half-empty.
But linking modern reality to the megadroughts of history is something new — and researchers say this and other changes to our language matter for the future.
The current megadrought in the Southwest is defined not so much by declining precipitation — although that did have an effect too — but by increasing temperatures from climate change. That’s going to continue to climb as long as we keep burning greenhouse gases.
Udall and Jonathan Overpeck, dean of the School for Environment and Sustainability at the University of Michigan, have spent more than a decade studying the effect of this warming on the Colorado River, a crucial water source in the West. The river irrigates 5 million acres of farmland, provides water to 40 million people in seven states — including in the West’s biggest cities like Los Angeles, Phoenix and Denver — and helps keep the lights on in the “city of lights,” among other towns.
This exploitation has come at an ecological cost, though. Thanks to diversions for our various human uses, the river now runs dry before it reaches the sea. More water rights have been allotted than nature can provide, which is undoubtedly a management issue (although a complex one to solve), but in the last two decades this is being more acutely felt.
In part that’s because less water is running off into the basin.
Udall and Overpeck found in a 2017 study published in Water Resources Research that Colorado River flows between 2000 and 2014 were 19% below normal. Reduced rainfall was partially responsible. But on average, they found, about one-third of the runoff decline resulted from warming temperatures from human-caused climate change.
Higher temperatures from this “hot drought,” as it’s also called, means more evaporation from water bodies and soil, more evapotranspiration from plants and more sublimation from snow. For the West, where water resources are stretched thin already, this can have far-reaching economic and ecological consequences.
Which brings us to another proposed change in the way we describe things.
In a 2018 paper the Colorado River Research Group, which includes Udall and Overpeck, called for new language to describe the scientific reality on the ground. The term “drought,” they wrote, wasn’t accurate.
“Aridification,” they argued, was a more fitting description.
The semantics here are important.
Aridification, they explained, “describes a period of transition to an increasingly water scarce environment — an evolving new baseline around which future extreme events (droughts and floods) will occur.”
Or more simply: Drought is temporary. Aridification is permanent.
This reinforces the fact that climate change isn’t a distant phenomenon, but one that’s already underway and causing life-altering changes. Depending on where you live, it’s causing more severe floods, destructive hurricanes, prolonged droughts or lengthened fire seasons.
And it’s here to stay, given our current course. The “new normal” of climate change could, like megadroughts, be felt for decades.
“We’ve been wanting to make the case that this is not a normal drought,” says Udall. “A drought implies that some kind of return to normalcy will occur in the near future, and that’s not what we’ve seen and not what the science tells us is likely to happen.”
This isn’t a problem contained to just the Colorado River basin or the Southwest, either.
Warmer summer temperatures are likely to reduce flows in other key western rivers, including the Columbia River in the Pacific Northwest, and rivers across California’s Sierra Nevada, other research has shown. And warming temperatures are driving similar changes further east, too.
A new study in the Proceedings of the National Academy of Sciences examined flows in the Missouri River, the country’s longest river, which cuts through the Midwest. The researchers, led by USGS scientist Justin Martin, found that during the first decade of the 2000s the Upper Missouri River Basin had drought conditions “unmatched over the last 1,200 years.”
The culprit? Warming temperatures from climate change that reduced runoff from snowfall in Rocky Mountain headwater streams that feed the Missouri.
Same story, different river.
But while that paper did occasionally use the term “megadrought,” it mostly characterized what’s happening in the Missouri as a “severe drought.”
Framing the problem in that manner, some say, may not be enough to convey the seriousness of the situation or to inspire action from water managers and the public.
To change the narrative, we have to change the framing, Udall and Overpeck argue in a new commentary published in the Proceedings of the National Academy of Sciences, in response to the Missouri River study. Thinking of what’s happening on the Missouri, and other rivers across the West, as a drought, they wrote, ignores the real and long-term effect that warming temperatures will have on our rivers.
“This translates into an increasingly arid Southwest and West, with progressively lower river flows, drier landscapes, higher forest mortality, and more severe and widespread wildfires,” they wrote, “not year on year, but instead a clear longer-term trend toward greater aridification, a trend that only climate action can stop.”
And that gets to about the only good news in any of the recent research. We know what’s causing the problem. We just need to do something about it.
A first step is making sure changes in water-management policy reflect scientific reality, and that’s where using language for planning that matches the task at hand becomes crucial.
Water managers traditionally use the past as a guide by examining the hydrologic record to calculate important baselines for the average high and low flows, the size of possible floods and the length of probable droughts.
But that’s all changing now “because the future is no longer going to look like the past,” says Eric Kuhn, the former general manager of the Colorado River Water Conservation District and coauthor of the book Science Be Damned: How Ignoring Inconvenient Science Drained the Colorado River. Now, he says, “water managers are trying to move forward in what we call ‘deep uncertainty’” — a process that requires planning for any number of plausible futures, including a very dry one.
We will get a chance to see what this looks like at the basin-scale as a seven-year process to renegotiate how the Colorado River is shared among its many uses is now underway.
Whether those at the table take to heart the scientific findings about the prognosis for “aridification” and “megadrought” will have big ramifications on the future ecological, economic and political health of the Colorado River basin.
Outside the basin the larger work continues as well.
“The sooner emissions of greenhouse gases to the atmosphere are eliminated,” Udall and Overpeck concluded, “the sooner the aridification of North America will stop getting worse.”
The state of Colorado will embark on the second phase of studying a potential water-savings plan, this time by developing a draft framework to test how the structure and design of such a program could work.
The Colorado Water Conservation Board approved at its regular meeting Nov. 18 a Step II Work Plan for its investigation into the feasibility of a demand-management program.
“People in my basin, including myself, are very excited to get down the road of this next phase,” said CWCB board member Jackie Brown, who represents the Yampa, White and Green river basins. “I think it will bring us a lot of certainty with where we end up on this really heavy issue.”
Since June 2019, eight workgroups composed of water experts from different sectors around the state have been hashing out the potential benefits, downsides and challenges of a voluntary and temporary program that would pay water users to cut back in order to leave more water in the Colorado River. The workgroups tackled eight subject areas: law and policy; monitoring and verification; water-rights administration and accounting; environmental considerations; economic considerations and local government; funding; education and outreach; and agricultural impacts. A ninth workgroup, led by the Interbasin Compact Committee, focused solely on equity.
Their work is now done. The results of a year’s worth of meetings, in-depth discussions and workshops resulted in a 200-page report, released in July.
A project management team, made up of state officials from the CWCB, the Division of Water Resources and the attorney general’s office, will now take the input from the workgroups and use it to begin Step II. The overarching goals of this phase are to figure out if demand management would be achievable, worthwhile and advisable for Colorado.
“Ultimately, again, the question is: Is demand management a feasible tool to protect Colorado water users against the risks and impacts of a potential curtailment, and can we create some additional benefits as well?” said Amy Ostdiek, CWCB deputy section chief for interstate, federal and water information.
At the heart of a potential demand-management program is a reduction in water use in an attempt to send water downstream to Lake Powell to bolster levels in the giant reservoir and meet 1922 Colorado River Compact obligations. If Colorado does not meet its obligation to deliver water to the lower basin, it could face mandatory cutbacks, known as curtailment.
Under such a program, agricultural water users could get paid to temporarily fallow fields and leave more water in the river, in order to fill a 500,000 acre-foot pool set aside in Lake Powell as a modest insurance policy. But developing a program raises many thorny questions such as how to create a program that is equitable and doesn’t result in negative economic impacts to agricultural communities.
In Step II, the project management team, with the help of consultants SGM, CDR Associates and WestWater Engineering, will develop a draft “strawman” framework of a demand-management program. Step II does not include a large-scale pilot program, but it leaves the door open to develop one in the future, potentially in collaboration with other upper-basin states. Ostdiek said the project management team should have the initial draft framework ready for the board to look at early next year.
CWCB Director Rebecca Mitchell reminded board members that demand management is just one tool — but an important one — that the state is looking at to deal with looming water shortages.
“When we look at the challenge of a changing climate or a changing hydrology and the frequency and drought and the intensity of drought, it would be irresponsible of us not to look at every tool available,” she said. “I think this is the next, right, appropriate step.”

Opinion: We’ve known for years that a shortage is coming, but it’s alarming how quick the conditions are changing. The Colorado River system was not set up for this.
This warm, dry weather we’ve been having may be good for moving activities outside.
But it’s bad news for our water supply.
The chances are growing – and quickly – that a warm, dry winter could push Lake Powell to a trigger point about a year from now that could result in significantly less water for Lake Mead, which supplies about 40% of Arizona’s water supply.
That likely would push Mead into a first-time shortage declaration. And if the same thing were to happen the following year, it would likely plunge Mead into a more severe shortage – a depth from which the lake is unlikely to recover any time soon.
Like I said, bad news.
Why would Mead get less water?
The 2007 operational guidelines lay out how much water is released from the upstream Powell to the downstream Mead. In “normal” years (and yes, I use quotes because nothing about the Colorado River is normal these days), Mead gets about 8.23 million acre-feet.
That drops to 7.48 million acre-feet once Powell’s levels fall below a certain depth. This occurred once before, in 2014, and luckily, Mead was nowhere close to a shortage then.
But lake levels plunged that year and never recovered, even in wet years and despite millions of acre-feet of water that Arizona and others have stored in Mead.
The lake is currently less than 10 feet above its shortage elevation trigger of 1,075 feet. Yet a 7.48 million acre-feet release in water year 2022, which begins in October 2021, could drop levels on Lake Mead by nearly 20 feet.
That could plunge us into shortage
That would place us solidly into a Tier 1 shortage – which for Arizona, means no more Colorado River water for Pinal famers and some water lost from the non-Indian agricultural (NIA) pool, which is a rung higher on the priority list and despite its name, mostly supplies tribes and cities.
Should conditions persist and Mead get another 7.48 million acre-feet release in water year 2023, that would likely plunge us deep into a Tier 2 shortage, nixing most of the NIA water that some cities use for existing development and others had wanted to shore up their long-term supplies.
Without that water, cities will need to find other, more secure sources. Which means if the battle to transfer water from on-river communities to Queen Creek is fierce now, new ones are likely to get a lot fiercer.
How likely is this 7.48 scenario?
We’ve known for years that a shortage would eventually come to Lake Mead, and that when that happens, Arizona – the state with junior water rights – would be the first to face more severe consequences.
But it’s alarming how quickly the conditions are changing.
The chances of a 7.48 million acre-feet release have increased markedly – from less than 20% in April to more than 50% in August, depending on which hydrology forecast you use. The chances of a Tier 1 shortage on Mead were as high as 30% in August, up from roughly 10% in April.
That may not sound like a lot, but it’s enough to keep risk-adverse water managers up at night. Consider that a 1 in 5 chance of Lake Mead tanking was enough to drive ratification of the Lower Basin Drought Contingency Plan, which buys time for the lake through mandatory cuts to our water supply.
So, what is provoking such quick forecast changes?
Last winter was relatively wet. It looked like we were on par for an average runoff year. But the ground was dry before all that snow fell, and as it began to melt, a lot of it sunk into the parched soil.
In the space of a few weeks, what looked like a decent runoff year turned into a mediocre one.
Then we had a record-breaking hot and dry summer. The soil is again parched.
But, unlike last winter, we are now in a relatively strong La Nina weather pattern, which historically has meant warm and dry winters for all but a small corner of the Colorado River basin.
It’s a double whammy. If this winter plays out as expected, we’ll have a meager snowpack that is unlikely to produce much runoff because warm winds blowing over the snow can suck out moisture. And much of what is produced could sink into the ground before it ever makes it to our reservoirs.
If this is the future, then what?
It’s early in the snow season, of course. Things could change.
But while few parts of the Colorado River basin were facing drought conditions a year ago, most are now in extreme or exceptional drought, the most severe categories.
And some worry that this could be the beginning of a multiyear string of similar dry conditions – a la what we saw most recently in 2012-13, the lead-up to the last 7.48 million acre-feet release on Powell.
The good news, if you want to call it that, is that Arizona’s water leaders already assumed that we’d already be in a Tier 1 shortage by now. We have plans to handle these shortages in the short term, even if the details – like forcing Pinal farmers back solely on groundwater – are less than ideal.
The more daunting challenge lies in 2026, when the drought contingency plan and the 2007 guidelines expire. Because, as bad as this winter may look, the science suggests we are in for many more of them as the Colorado River basin gets warmer and drier.
We have a system that assumes water allocations will be steady as she goes, when the best-case scenario may be one of feast or famine.
And all signs point to a future where every competing water use is a valid one and there isn’t enough water to quench them all.
How do we decide who gets what when a dwindling supply becomes even more volatile? That is the fundamental question we must now address.

There’s a concept called “demand management” in the news in Colorado, and here’s a simple definition: Landowners get paid to temporarily stop irrigating, and that water gets sent downstream to hang out in Lake Powell.
It’s an idea long talked about because of increasing drought and the very real danger of both Lake Mead and Lake Powell dropping into “dead pool” where no hydropower can be generated. But fears keep arising about what water markets mean. To some rural people, the idea of separating water from the land sounds like heresy.
Here’s how Andy Mueller, general manager of the Colorado River District sees it: “Just talking about demand management has already attracted deep-pocketed investors, whose motives are money and not for maintaining a healthy river.”
But James Eklund, former head of the Colorado Water Conservation Board, and who shares credit for creating Colorado’s version of demand management, thinks setting up demand management in Colorado is crucial.
“We need to act now,” he said. “Last winter and spring, where 107 percent snowpack turned into 52 percent runoff, was proof we’ve entered a deadly phase where millions of acre-feet of water need to be stored in Lake Powell.”
These days, Eklund is a lawyer for the New York investment company, Water Asset Management (WAM), whose land purchases in Mesa County have sounded alarms about outsiders speculating on water. State Sen. Kerry Donovan, Democrat from Vail, has co-sponsored what could be called an anti-WAM bill, aimed at beefing up the state’s water anti-speculation laws.
“If we don’t do demand management correctly,” Donovan warned, “we are going to create a commodity-based situation where water goes to the highest bidder.”
Eklund’s rejoinder: “Like it or not, we live in a capitalist system.”
Jim Lockhead, president of Denver Water, argued that by not putting demand management into place, increasing drought could bring about a crisis: “Water rates would spike in cities, just as farm income and output would plunge region-wide.” Without demand management, Lockhead predicted, there would be “an economic black hole.”
To test demand management, four municipal water districts, including Denver Water, funded a pilot program in 2015-2019. It stored 175,000 acre-feet of water in Lake Mead by paying irrigators in Arizona, California and Nevada to fallow fields and forgo cultivation.
Applications rose annually, according to the U.S. Bureau of Reclamation, which funded 53 percent of the study. The rest, 47 percent, came from the four water districts and the Walton Family Foundation. Eklund wants the same players to back Colorado’s program, the first of the Upper Basin states to attempt demand management.
“BuRec built all the dams possible (and) they should steer into conservation,” Eklund said.
But to gain participation in the pilot program, water prices were set at levels that boosted farm incomes above what agriculture alone would produce. That raise in income also increased the value of their land.
Mueller doesn’t like what that could lead to: “That will squeeze out future mom-and-pop operators. Ninety-five percent of Western Slope irrigators are owner-operators and we don’t want that declining.”
Although the Colorado Water Conservation Board hasn’t ironed out how to “shepherd” the water downstream or who will round up willing sellers, investors from outside of Western Colorado are already buying up land with senior water rights.
“We are seeing large, well-financed purchasers — ostensibly agricultural organizations — coming into the Gunnison basin,” said Steve Anderson, who manages the Uncompahgre Valley Water Users Association, a canal company in Montrose County. In Delta County, the Conscience Bay Company, operating out of Boulder, bought the 3,000-acre Harts Basin Ranch, with senior water rights on the Grand Mesa.
Yet, the new owners are hardly quick-buck artists. They have expanded the cattle herds, improved irrigation and hired locals.
For the new water owners, it’s a waiting game until demand management exists and water comes with a price. As drought worsens, the owners of these senior water rights — whether they are from New York City or Texas — could well be sitting on a fortune.
The four states in the upper basin, including New Mexico, are working on demand management plans to reduce the risk they will be mandated to reduce water use to fulfill obligations of the 1922 Colorado River Compact.
While this could reduce the risk to the water users, New Mexico Interstate Stream Commission Director Rolf Schmidt-Petersen told the San Juan Water Commission that he is not highly optimistic that the upper basin states can reach an agreement about demand management and storage. He said coming to an agreement on these topics will take a while…
Recognizing that drought could strain the limited supplies in the river, both the upper and the lower Colorado River basins have created drought contingency plans. One key element of the upper basin plan is demand management. This means water users can be paid to temporarily reduce their water consumption and the water saved through that method would be placed in one of the upper basin reservoirs, such as Navajo Lake.
If a situation arose where the upper basin could not reach its contractual obligation to deliver water to Lake Powell, the water stored in one of those reservoirs would be released to meet those requirements.
The details about demand management are still being worked out and, on Nov. 4, representatives from the New Mexico Interstate Stream Commission provided the San Juan Water Commission with an update on those efforts.
Schmidt-Petersn said there is only a small chance that there will be a call on the river that would require the upper basin to curtail use, but the demand management proposal will protect the water users if such situation arose.
Currently, New Mexico is in the stakeholder outreach process of developing a demand management plant, according to Ali Effati, who presented on behalf of the Interstate Stream Commission.
Effati said demand management could be easier to set up in New Mexico than in other upper basin states due to the proximity to Lake Powell, however there are still questions that remain such as how to shepherd the water that is released to meet the compact requirement and make sure that it makes it into Lake Powell.
All four upper basin states — Colorado, Utah, Wyoming and New Mexico — must agree on demand management and storage, as must the Upper Colorado River Commission. This type of agreement may be hard to achieve, Schmidt-Petersen warned, as each state works to protect its own interest in the Colorado River water.
San Juan Water Commissioner Jim Dunlap, who represents rural water users, emphasized the importance of having a way to meet the Colorado River Compact requirements even if a drought reduces the flows significantly in the rivers.
New Mexico currently does not use all the water that it is allocated and Dunlap said that furnishes a “false benefit” to the lower basin states and could lead to challenges if New Mexico chose to increase its utilization of its allocated water.
Farmington Community Works Director David Sypher highlighted an area that could create challenges: how to fairly share the burden of water shortages. If a drought does occur, entities will have to cut back. But Sypher said the City of Farmington has already invested in efforts to conserve water such as leak detection, storage and maintenance. This has led to higher water rates for customers.
Sypher said conservation is a huge part, if not the most important part, of demand management.
FromThe Grand Junction Daily Sentinel (Dennis Webb):
A 2007 deal creating guidelines governing how Lake Powell and Lake Mead are operated in coordination isn’t scheduled to expire until 2026. But water officials in Colorado River Basin states are already beginning to talk about the renegotiations that will be undertaken to decide what succeeds the 2007 criteria.
“I think the guidelines have been a big success,” John Entsminger, general manager of the Southern Nevada Water Authority, said Wednesday during the 10th annual Upper Colorado River Basin Water Forum. The forum is put on by Colorado Mesa University’s Ruth Powell Hutchins Water Center and this year is taking place online due to the pandemic.
The 2007 criteria dictate how much water must be released each year from Powell into Mead, in an effort to equalize water levels in the two reservoirs. The criteria are important to Colorado and other states in the Upper Colorado River Basin because those states rely on Powell water storage for meeting long-term delivery obligations to downstream states based on a 1922 interstate compact.
Amy Haas, executive director of the Upper Colorado River Commission, which represents Upper Basin states, said she thinks the 2007 guidelines have reduced the “safe yield” of water for the Upper Basin. Even with low inflows into Powell, the guidelines resulted in releases of 9 million acre-feet a year of water from Powell every year from 2015-19, compared to the 8.3 million acre-feet negotiated average minimum objective, she said.
Entsminger called that a simplistic analysis that cherry-picks data. He says his entity’s modeling indicates that under the 2007 criteria there is more water in Powell and less in Mead than otherwise would have been the case.
Tom Buschatzke, director of the Arizona Department of Water Resources, said that with the guidelines in places, Powell water levels largely have remained around 50% of capacity “through some horrendously dry years” and only three or four years of above-average inflows.
The criteria encourage water conservation and provide rules for determining water shortages and reducing water use by Arizona and Nevada.
Entsminger said the 2007 agreement increased cooperation and communication among states in the river basin, provided certainty by operating the two reservoirs together, and headed off litigation only two years after states were close to going to the Supreme Court over river water issues…
Those states are evaluating the possibility of demand management measures to temporarily curtail agricultural, municipal and other use during droughts. The goal is to bolster Powell levels with water that could be reserved for compact delivery obligations. But Haas said it’s important to assess the risk of curtailment of Upper Basin uses occurring as well. Such a curtailment has never happened.
The “bathtub ring” at Lake Powell evidences lower flows coming into the reservoir. According to preliminary data from the Bureau of Reclamation, the total inflow into Lake Powell for the 2020 water year was about 6 million acre-feet, just 55% of average.

Grand County rancher Paul Bruchez stands in a hay field near Kremmling, holding a small tuft of hay between his fingertips, twirling it back and forth, seeing how quickly it disintegrates after a summer without water.
The plant, known as timothy, is native to Colorado and feeds thousands of cattle here in the Upper Colorado River Basin.
This hay species and others are being closely watched this year as part of a far-reaching $1 million science experiment, one designed to see if ranchers can take water off of hay fields and successfully measure how much was removed, how much evaporated, and how much was used by plants. They also need to know how reducing their irrigation in this fashion affects the nutritional value of the hay.
If certain hay species retain more nutrients than others when they’re on low-water diets, then ranchers know their cattle will continue to eat well as they evaluate whether they can operate their ranches on less H20—not all the time, but perhaps every other year or every two to three years.
“We’ve spent centuries learning how to irrigate these lands,” Bruchez said. “Now we’re learning what it’s like not to irrigate them.”
Any water saved could be left in the Colorado River, allowing it to become more sustainable, even as the West’s population grows and drought cycles become more intense.
While similar small-scale experiments on five or 10 acres have been done before, this one by comparison is vast in scale, involving 1,200 acres of high-altitude hay meadows, nine ranch families, a team of researchers spread across Colorado, Utah and Nevada, and the backing of powerful water groups, farm interests, and environmentalists.
“We’ve never had a project this large in the state of Colorado,” said Perry Cabot, a Colorado State University researcher who is the lead scientist on the project.
The undertaking is sponsored by the Colorado River Basin Roundtable, whose members include Bruchez.
“We set out on a mission to ensure we have as much science and data as possible,” Bruchez said.
The data being collected serves several needs. It should help ranch families see if they can afford to participate in these modern-era conservation efforts.
It will allow researchers to better understand what works on the ground and what to do, for instance, when rambunctious bulls destroy research equipment enclosures 25 miles from the nearest town.
And it will give policy makers insight into the political problems that will have to be solved, as well as how much money could need to be raised, to make large-scale conservation on the Colorado River feasible.
The $1 million, three-year project is being funded by the state and several environmental groups, with the money being used to pay researchers, buy equipment, and compensate ranch families who temporarily fallow their fields.
Water for Powell?
Agriculture uses some 80 percent of the water in the seven-state Colorado River Basin, and hay meadows that grow feed for cattle are among the basin’s largest water users.
Last year, under an historic drought agreement on the Colorado River, a new specially protected drought pool in Lake Powell was authorized.
Now Colorado, Utah, Wyoming and New Mexico, the four states that comprise the Colorado River’s Upper Basin, above Lake Powell, are studying whether they can or should help save enough water to fill that drought pool. The pool, authorized at 500,000 acre-feet, is intended as further insurance that the Upper Basin won’t be forced to involuntarily reduce water use from the river under the terms of the Colorado River Compact.
Colorado expects it would need to provide roughly half the water for the drought pool, and, led by the Colorado Water Conservation Board, is working out difficult questions about how that water would be saved and ushered downstream to Lake Powell under a possible voluntary program known as demand management. The research being done near Kremmling will help answer several critical questions.
Wendy Thompson is a rancher who also serves as the research technician for the pilot program, cutting hay samples and gathering soil moisture and precipitation data, among dozens of other tasks. She has driven hundreds of miles across Grand County this summer, checking each of the program’s 24 research sites every week or so, lugging an aging laptop from one meadow to the next.
She knows better than most that ranch families will need real information, such as how fallowing affects crop yields and soil health and production costs, in order to make decisions about whether to join in a voluntary multi-state conservation effort or to back away.
Intuition vs. facts
“The experiment is important to us,” Thompson said. “We want to make decisions based on the science and the data, not a gut feeling.”
Much of the work is grueling, like cutting hay samples week after week, and low tech, like measuring water levels in rain gauges.
But dramatic advances in satellite imagery and global evapotranspiration databases are helping people like Perry Cabot create science-based templates that eventually will be useful not just in Colorado, but Wyoming, Utah, New Mexico and perhaps even farther downstream, on cotton fields in Arizona and avocado groves in California’s Central Valley.
“We now have the ability to measure the whole field,” Cabot said. “It’s becoming more accurate and it’s tremendously convenient if you’re trying to get a good understanding of patterns. We don’t have to rely on one data point anymore.” [Editor’s note: Cabot sits on the board of Water Education Colorado, which is a sponsor of Fresh Water News.]
That this particular team has agronomists, economists and environmentalists pitching in with their expertise is also helping move the science forward.
“What makes this different is the scale and the depth of the questions we’re asking,” said Aaron Derwingson, an agricultural water specialist with The Nature Conservancy’s Colorado River Program, which is helping to fund the project.
“When we’re done it will be relevant to more people than just the ranchers. We will be able to extrapolate these field conditions and what it means for water savings and the recovery of different species,” he said.
“It’s tough to figure all that out on paper. Here we’re getting down to brass tacks,” Derwingson said.
With irrigation season over, Cabot and his team have serious number crunching to do before they begin monitoring next year, measuring how the hay fields survived their fallowed season, how quickly they return to health, and precisely how much water was conserved.
Early estimates indicate that the ranchers may have saved 1,500 acre-feet to as many as 2,500 acre-feet of water this year. If this process can be replicated, scientists and ranchers could begin to see how long it might take to fill the 500,000 acre-foot drought pool at Lake Powell.
No collateral damage
But even more important to Bruchez and state policy makers is the impact the pilot is having on a highly skeptical ranching community, some of whom are deeply worried that they will lose control of their water.
“We wanted a project that would be as smooth as possible,” Bruchez said. “We wanted to simplify it and ensure there weren’t unintended damages to neighbors who weren’t participating.
“Some people were comfortable about what we were doing and others had great fears,” he said. “We just had to keep telling them, ‘We are not delivering water to Lake Powell. We are trying to fill data gaps.’”

With another drought year draining the Colorado River system, a new economic study suggests that a wide-scale water conservation program in Colorado to reduce stress on the river could cost more than $120 million, depending on the amount of water saved for use in the program.
The study examined how much money it would take to adequately compensate ranchers and farmers who agree to temporarily remove water from Colorado’s West Slope hay meadows and corn fields using a practice known as fallowing. It also looked at how such a conservation program would affect the farm economy and the communities and workers who rely on it for jobs.
“Potentially the program could be beneficial to the participants,” said BBC Managing Director Douglas Jeavens, a principal with BBC Consulting, which conducted the work. “The payments have to be large enough to offset any losses,” he said.
The water saved would go into a special drought pool in Lake Powell. The pool is envisioned as a way for Colorado and other states in the Colorado River Basin’s Upper Basin—Wyoming, Utah and New Mexico—to further protect their ability to use the river’s water even as Lake Powell continues to shrink.
Kathleen Curry, a former lawmaker and rancher in the Gunnison River Basin, said the analysis covered all the variables at play.
“I thought they did a good job,” she said. “The numbers they came up with are reasonable.”
The study looked at two different scenarios. Under a moderate scenario it examined the impact of fallowing 25,000 acres of West Slope land annually over five years, and an aggressive scenario under which 100,000 acres of land would be fallowed for the same period of time.
The study, released Sept. 25, was sponsored by the Glenwood Springs-based Colorado River District, the Durango-based Southwestern Water Conservation District, and Tri-State Generation and Transmission. It adds important new detail to a statewide discussion about whether Colorado should participate in the drought pool.
Since the state began studying the pool’s feasibility in 2019, West Slope ranchers have said repeatedly that they can’t make a decision about whether to participate if they don’t know how much money they would be paid and how such a program would affect the local economy.
The study provides some preliminary answers.
Across the Yampa, Colorado, Gunnison and Dolores river basins, under the moderate scenario, ranchers would see a net benefit of nearly $9 million, while under the aggressive scenario, the net benefit would rise to $36 million over a five-year period. The water in the study was priced in a range starting at $194 an acre-foot and rising to $263 an acre-foot.
Individual ranchers who agree to fallow 100 acres of land could see an annual benefit, after expenses, of more than $50,000 under at least two scenarios, according to BBC’s analysis.
In modeling changes to the economy, the study found that 55 jobs would be lost under the moderate scenario, while 236 jobs would be lost under the aggressive scenario.
It also found that hay prices would rise 6 percent as supplies tighten and livestock populations would shrink by 2 percent.
Another key concern for ranchers and others is whether taking water off the fields could harm other water users on the river farther downstream.
“This is a critical issue,” said Jeavens. “But we think looking ahead we could design a program that either reduces or eliminates that risk.”
The pool would be filled with 500,000 acre-feet of water, roughly half of which would likely come from Colorado, should it, along with Wyoming, Utah and New Mexico, agree that filling the drought pool is doable.
Under a broader statewide study also underway, ranchers and cities would be asked to voluntarily set aside water for the drought pool and would be paid for whatever water they contributed to the program.
The Colorado Water Conservation Board, which is conducting the statewide feasibility analysis, declined to comment on the West Slope economic study.
Whether Colorado’s Front Range will embark on a similar study focusing on its contributions to the conservation program isn’t clear yet.
Previously Front Range cities have said they would be willing to contribute whatever water and/or cash is necessary to fill the drought pool in a way that is fair to cities and agricultural producers, as well as to different regions of the state.
The Colorado River, which starts high in Rocky Mountain National Park, supplies roughly half of the drinking water on the Front Range and is also used to irrigate millions of acres of hay meadows, corn fields and other crops on both the West Slope and Eastern Plains.
But if the drought-stressed river continues its decline, it could feasibly trigger involuntary cutbacks under the Colorado River Compact for the Upper Basin states, affecting both Colorado’s West Slope and Front Range.
Though such a scenario is still considered unlikely, policy makers and others want to see Colorado develop some kind of insurance against such a catastrophic event.
Who would pay for the conservation program remains to be decided. Some have suggested that thirsty state’s in the Colorado River’s Lower Basin—California, Nevada and Arizona—ante up any needed cash. Others believe that a new set of fees or taxes could fund the ambitious effort.
Don Schwindt, a rancher who sits on the board of the Southwestern Water Conservation District, said the study is a good step forward, but he wants more detailed analyses.
“These numbers are as good as any that have been generated. But the simple answer right now is that this is not enough money to generate the water. For my operation, I have to have a higher dollar than those averages or I am going to go broke.
“We’ve moved forward,” he said, “but we don’t have anything we can take to the bank yet.”

Here’s a guest column from Hannah Holm that’s running in The Grand Junction Daily Sentinel:
Lately, I’ve been savoring clear skies like never before. My appreciation was magnified by days of feeling trapped in the smoke from California fires, even as our own Pine Gulch Fire calmed down. Meanwhile, friends and family in Washington and Oregon are choking on airborne soup thicker than anything we’ve had to deal with this summer.
I feel vaguely guilty that the same weather system that finally brought us rain, cooler temperatures and clear air earlier this month also fanned the heartbreakingly destructive flames farther west. We share the air, and that gives us in western Colorado a direct, tangible connection to the fate of West Coast forests and fires.
Water connects us, too, even if the connections aren’t as immediate and visible as wildfire smoke. Most of the water that flows into the Colorado River comes from Colorado’s mountains, so a bad snow year (or decade, or two) for us means less water for the 40ish million people that depend on the river, from Denver to Phoenix, Los Angeles and Mexico. Likewise, more snow in California’s Sierra Nevada Mountains and the eastern side of the Rockies reduces the draw on the river by giving Los Angeles and Denver more source water closer to home. Conservation actions in those cities benefit the river, and the whole river community, for the same reason.
Downstream conditions affect the headwaters in other ways, too, as desiccated, beat-up rangeland in the Four Corners area sends dust to the mountains that melts the snowpack earlier and reduces the amount of water that runs off into our streams.
Food also connects us, and food is very directly connected to water. If you like to eat salad in January, you need to keep water flowing to the Southern California farms that produce it.
To bring us back to where we started, fire and water are also connected, just as both fire and water connect far-flung communities. When the Pine Gulch Fire was at its most active, incident managers reported that the moisture content of the vegetation in the fire area was less than what you would typically find in a (perfectly flammable) piece of paper. That was a direct consequence of the same high temperatures and precipitation deficit that have diminished our streamflows and runoff into Lake Powell. Post-fire, we can expect ash and naked soil to run off into waterways, fouling fish habitat and drinking water intakes.
All of these connections are important to keep in mind as the states that share the Colorado River prepare to embark on a new round of negotiations over how to manage it. Representatives from all the states will face pressure to focus narrowly on enabling local water users to secure access to as much of the shrinking river as they can. That’s fair enough — no one wants to diminish their own future just to be the nice guy. But over the long term, it will help all of us to pursue actions that benefit the Colorado River system as a whole. That includes reducing the greenhouse gas emissions that are warming the atmosphere and intensifying both drought and wildfire.

FromThe Grand Junction Daily Sentinel (Dennis Webb):
The secondary economic impacts of paying western Colorado farmers to temporarily fallow fields in times of drought could be similar to the secondary benefits resulting from the spending of those payments, a new study has found.
But BBC Research and Consulting says the dollars from payment spending would flow to different businesses, potentially shifting from smaller, agriculturally focused communities to larger towns and cities.
In addition, the payments would only benefit the regional economy if they come from outside western Colorado, because payments originating on the Western Slope would only result in shifting money around within the region as opposed to creating a new economic benefit, the study says.
The research was commissioned by the Colorado River Water Bank Workgroup, which consists of the Colorado River District, the Southwestern Water Conservation District, The Nature Conservancy, the Tri-State Generation and Transmission Association, the Uncompahgre Valley Water Users Association, the Upper Gunnison River Water Conservancy District and the Grand Valley Water Users Association.
It’s intended to help gauge the impact on local agricultural economies should Western Slope farmers participate in voluntary, temporary, compensated fallowing as part of a demand management program involving Upper Colorado River Basin states including Colorado.
Such a program is being considered as a means for the states to be able to store extra water in Lake Powell so they can continue meeting their water delivery obligations to downstream states in times of drought, and head off potential mandatory curtailment of water uses under an interstate compact…
The study looks at fallowing grass hay, alfalfa and corn. It estimates that regionally it would cost an average of $236 per acre-foot of water involved, or about $470 per fallowed acre, to get farmers to participate. It says producers also may require payments covering direct fallowing costs, such as weed and pest control, and payments also may have to be made to irrigation companies for lost revenues and added management costs.
The study evaluates a moderate, 12,700-acre hypothetical fallowing program involving 25,000 acre-feet of water a year for five years across western Colorado, and a more aggressive, 52,100-acre program that would involve 25,000 acre-feet a year for five years within each of four major Western Slope river basins.
The study finds that the moderate approach would result in a minimum of a $5.7 million annual reduction in crop production, and the aggressive approach, at least a $23.2 million reduction.
Those reductions would result in an estimated loss of at least 64 or 260 on-farm jobs, respectively, although most of those would involve the farmers themselves who are being compensated.
The study estimates that when comparing that compensation to their lost farm income, farmers collectively would come out at least $2.2 million ahead each year in the moderate scenario and $8.6 million ahead in the aggressive approach.
The bigger focus of the study is what secondary effects would result from the fallowing due to impacts on businesses such as farm and ranch suppliers, and businesses providing household goods and services to affected workers.
In the moderate scenario, the study estimates at least 55 secondary jobs would be lost to reduced crop production, while there would be an increase of at least 27 jobs resulting from spending of fallowing payments.
Under the aggressive scenario, at least 236 secondary jobs could be lost from reduced production, compared to at least 109 new jobs being supported related to payment spending.
But the study says there could be a net annual gain of $546,000 in secondary income from the fallowing under the moderate scenario, and $2.4 million under the aggressive one.
Doug Jeavons, managing director at BBC Research and Consulting, said that despite the net job loss, the new jobs that would be created could tend to be in banking and finance, and those could pay more than the lost farm-related jobs.
The fallowing would mean fewer sales of seed, fertilizer, hauling services and labor, but could boost spending in areas such as purchase of vehicles and farm machinery, with some of the fallowing payments also being used for household consumption and reducing debt…
The study also says annual net secondary income also could fall with fallowing, by as much as $393,000 under the moderate scenario and as much as about $1.46 million under the aggressive one.
This could happen if farmers spend less of their fallowing money locally. It also accounts for the possibility that reduced forage production from fallowing could affect the livestock industry, driving up hay prices and causing ranchers to reduce herd sizes.
It says that based on what has been historically seen when it comes to hay production declines in the region, the moderate fallowing approach could result in just over a 0.5% drop in livestock production and a $3 million drop in annual livestock sales, and the aggressive approach, a possible 2.2% production drop and $13.4 million annual revenue loss.
The Colorado River District said in its news release that its board hasn’t weighed whether a fallowing program is good for the Western Slope, but is gathering data through efforts such as the study to determine if it would have negative impacts, and if so, at what scale.
It also said if a demand management program is created in Colorado, Western Slope agriculture would only be part of the solution and Colorado River users in all parts of the state must contribute water to the program. This would include Front Range cities that divert that water across the Continental Divide…
Speaking on a river district webinar Thursday on the study, Sonja Chavez, general manager of the Upper Gunnison River Water Conservancy District, said any Western Slope fallowing program won’t be one-size-fits-all, and would have to be structured to address local concerns such as soil impacts…
One concern in her district is that parts of it may have such shallow soils that they could take three to five years to recover from fallowing.
Another consideration is that some western Colorado basins export substantial amounts of hay to other states, and even other countries.
If fallowing primarily reduced exports, effects on local livestock production might be minimal.
But BBC Research and Consulting’s report notes that hay exporters may be resistant to jeopardize customer relationships by fallowing fields…
BBC Research and Consulting says measures such as split-season versus full-season fallowing could reduce economic impacts from fallowing, and ensuring that participation is spread widely across and within various river basins could spread out the impacts.
Chavez likes the general idea of widely distributing fallowing, but says that could increase costs for monitoring such a program, evaluating results and ensuring that conserved water makes it downstream to be stored rather than being used elsewhere.
The state cited as a reason the 14,000 public comments submitted in response to a draft environmental impact statement (EIS) released in June.
The U.S. Bureau of Reclamation was supposed to have the final EIS out by November, with a final decision in January, but that ambitious time frame is expected to be pushed back while a “supplemental” analysis is conducted, according to Todd Adams, director of the Utah Division of Water Resources.
“The extension will allow more time to consider the comments and complete further analysis, which will contribute to a more comprehensive draft and final EIS,” he said. “When you think about the sheer volume of comments, it’s going to take some time.”
Among those comments was a bombshell request by the six other states that rely on the Colorado River for water to refrain from completing the EIS until the states work out their differences regarding the legality of diverting the water across major drainages…
“The Bureau [of Reclamation] comes out with a draft that says, ‘We [in Washington County] need another source of water,’ but they don’t say why. The EIS failed to consider a water conservation alternative,” said Zach Frankel of the Utah Rivers Council
Frankel and other pipeline critics speculated that commenters or higher-ups in the Interior Department had identified “fatal flaws” in the draft study that could render the pipeline’s approval vulnerable to legal challenges that are sure to follow.
“The delay of the environmental review affirms that Nevada and the other Colorado River Basin States are having an impact in this process against Utah,” said Tick Segerblom, who represents Las Vegas suburbs on the Clark County Commission. “With climate change and drought threatening us every day, we must be vigilant until the end. We cannot let our water supply be sucked away for golf courses and green lawns in southern Utah.”
From email from the Colorado River District (Alesha Frederick):
Study found demand management could result in fewer agricultural support jobs and reduce livestock production on the West Slope
The Colorado River Basin is in the 21st year of drought, and major reservoirs on the river are sitting at less than half full. There is growing concern that agricultural economies on the West Slope might be harmed if Colorado and other Upper Basin states (Wyoming, Utah and New Mexico) are unable to meet their obligations under the Colorado River Compact. With these concerns in mind, the state of Colorado is looking at ways to prevent such a crisis from occurring. One of the ideas Upper Basin states are discussing is paying water users to consume less water. The water saved would then be banked in Lake Powell. The states are calling it demand management.
The question is, if farmers and ranchers are paid to voluntarily fallow their fields, how would it change West Slope communities where agricultural businesses employ people, pay taxes and buy equipment? The recently released Upper Basin Demand Management Economic Study in Western Colorado sought to determine the secondary economic impacts that might occur if West Slope agricultural producers participate in a demand management program.
Consistent with its charge to represent and protect the Western Slope’s water interests, the Colorado River District has been actively engaged in statewide conversations about a potential Demand Management program. Through its participation in the Water Bank Workgroup, the District led the call for additional economic analysis that would help to inform the state’s decision whether or not to move forward with such a program.
“Our job is to protect West Slope water users. Studying the potential negative impacts of a new program such as demand management is vital to this work,” said Colorado River District General Manager Andy Mueller. “This secondary economic impact study ensures that agricultural producers on the West Slope have the information they need to make decisions about their farms and ranches. It’s part of the River District’s ongoing efforts to ensure water security for our farms, ranches, and rural communities.”
The Colorado River District’s Board of Directors has not weighed in on whether such a program is good for the West Slope. However, the Board is gathering data from efforts like this study to determine if such a program will have negative impacts, and if so, what the scale of those impacts is likely to be.
While the study examined the impacts of fallowing West Slope agriculture if a demand management program is created in Colorado, Western Colorado agriculture will only be one piece of the solution. If such a program is implemented, all types of Colorado River water users in all regions of the state must contribute water to the program. This study is not an endorsement of demand management but a study of its potential impacts.
The study examined two scenarios, a moderate and aggressive demand management program. The moderate demand management scenario considered a 25,000 acre-feet per year reduction in consumptive use by Western Colorado agricultural users for five years, while the aggressive scenario considered 25,000 acre-feet per year within each Western Slope river basin over a 5-year timeframe.
These are some of the key findings of the study:
* To pay producers at a level that they would incentivize participation in such a program, annual payments to irrigators are projected to range from an average of $194 per acre-foot under the moderate scenario to $263 per acre-foot under the aggressive scenario.
* For compensation payments and spending of those payments to benefit the regional economy, funding for those payments must come from outside of Western Colorado. If all that money was raised in Western Colorado, the payments would shift money around within the region, but it would not create a new economic benefit to offset the impacts.
* Growers producing forage crops including grass hay, alfalfa and corn are most likely to take part in such a program compared to fruit growers and small grain producers.
* Reduced production of forage crops, mostly hay, would require fewer purchases of items such as seed, fertilizer, labor, hauling and other services. This in turn could lead to a loss of an estimated 55 agricultural support jobs under a moderate scenario and 236 jobs under the aggressive scenario. Jobs supported by demand management payments could look very different from the jobs currently supported by hay production.
* Under an aggressive demand management scenario, a demand management program could increase local hay prices by about 6% and decrease the regional livestock inventory by about 2%. The potential price and livestock impact under the moderate demand management scenario would be much smaller.
The study was completed by BBC Research and Consulting and commissioned by the Colorado River Water Bank Workgroup made up of the Colorado River District, Southwestern Water Conservation District, The Nature Conservancy, Tri-State Generation and Transmission, the Uncompahgre Valley Water Users Association, Upper Gunnison River Water Conservancy District and the Grand Valley Water Users Association.
Here’s the release from Aurora Water (Greg Baker):
Reservoir release being made in cooperation with State Engineers Office
Beginning Wednesday, September 23, 2020, the Homestake Partners, which is comprised of Aurora Water and Colorado Springs Utilities, will make a one-time release of approximately 1,800 acre feet of water from Homestake Reservoir in Eagle County. The objective of this reservoir release is to determine the effectiveness of current administrative practices in shepherding released water from Homestake Reservoir, located south of Minturn, CO, downstream to the Colorado State Line.
This pilot project was developed by the Front Range Water Council and utilizes water contributed by Aurora Water and Colorado Springs Utilities, as well as by the Pueblo Board of Water Works. This water will be released from Homestake Reservoir into Homestake Creek, which is tributary to the Eagle River and the Colorado River.
The pilot release protocols were developed cooperatively with the Colorado State Engineer’s Office, with the release expected to provide the State and Division Engineers, as well as water users on the West Slope and East Slope, with valuable information related to compliance with the Colorado River Compact and the Upper Colorado River Compact. The project will test important aspects of administration practice. It will also provide data on hydrologic influences that would affect the timing and amount of the arrival of the released water at the state line.
“For municipalities that rely either wholly or partially on the Colorado River for their drinking water, it’s critical to understand all of the potential aspects a compact curtailment could have on our supplies,” said Pat Wells, General Manager for Water Resources and Demand Management for Colorado Springs Utilities. “Gathering this data before we get to that point will help us all plan for the future.”
As the water is released into Homestake Creek and travels downstream to the Eagle River and the Colorado River, the State Division of Water Resources will “shepherd” or facilitate the released water to the state line. The release of 1,800 AF represents contributions of 600 AF each by Colorado Springs Utilities, Pueblo Board of Water Works, and Aurora Water. This will not put any of the entities’ storage at risk; for example, 600 AF represents less than 0.3% of current system-wide storage in Colorado Springs Utilities’ raw water system and less than 0.4% of Aurora’s storage.
“The timing is perfect for this sort of investigation,” stated Alexandra Davis, Deputy Director for Water Resources for Aurora Water “Our reservoirs are well positioned at this time, even with the current drought conditions, and the lower flows in the rivers mean we will generate valuable information regarding protocols and practices currently in place for releasing stored water.”
The release is scheduled to occur Sept 23 – Sept. 30 and will produce flows of less than 175 cfs (cubic feet/second). These flows are higher than normal for this time of year in Homestake Creek and Eagle River, but within normal spring/summer runoff levels. There is no inundation concern for property adjacent to the tributaries.
The project also has the support by Boulder-based Western Resource Advocates.
“We are pleased these Front Range communities are taking a proactive step to address questions about conserving municipal water and shepherding saved water downstream,” Laura Belanger, senior water resources engineer and policy advisor with Western Resource Advocates said. ”This test release will help us understand potential benefits for water security and streams and demonstrates that all Colorado communities have an important role to play in ensuring a sustainable water future for Colorado.”
For the West this summer, the news about water was grim. In some parts of California, it didn’t rain for over 100 days. In western Colorado, the ground was so dry that runoff at first evaporated into the air. And in New Mexico and Nevada, the rains never came.
Bill Hasencamp is the manager of California’s Metropolitan Water District, which provides treated water to 19 million people. What was most unfortunate, he said, was that, “the upper Colorado Basin had a 100 percent snowpack, yet runoff was only 54 percent of normal.” In 2018, a variation happened – light snow and little runoff, which doesn’t bode well for the future.
What everyone wants to know, though, is who loses most if severe drought becomes the norm…
What makes the Western Slope of Colorado most vulnerable to drought is a pact among seven states signed in 1922. It bound the states to give priority in a water crisis to the Lower Basin states of California, Arizona and Nevada, potentially leaving the Upper Basin states of Colorado, New Mexico, Utah and Wyoming high and dry.
A crisis could be approaching. The two giant reservoirs on the Colorado River are both below 50 percent of capacity. If drought causes even more drastic drops, the Bureau of Reclamation could step in to prioritize the making of electricity by the hydro plants at lakes Mead and Powell. No one knows what BuRec would do, but it would call the shots and end current arrangements.
Before that happened, California could “call” for the water it is owed — 4.4 million acre-feet annually. In that case, Wockner said, ranches and farms would be forced to go dry before city residents suffered.
For now, California has avoided flexing its muscle to get its fair share of the Colorado River. To stop the Colorado River’s reservoirs from dropping to “dead pool” where power generation fails, California acts as if serious drought never ended. Since 2000, when the punishing drought began, California has cut annual water consumption by 30 percent, using both carrot and stick.
California charges the highest water rates in the West and also pays for efficiency. Under a program called Cash for Grass, “A good size lawn removal can net a homeowner $30,000,” said Rebecca Kimitch, who works for the Metropolitan Water District.
The state also invests in smarter irrigation, piping leaky ditches in the Imperial Valley, the Colorado River’s biggest irrigator. And it invests in desalinization plants and reuses some of its water via a program that was first derided as “toilet-to-tap.” More recently, statewide laws restrict personal daily consumption to a measly 55 gallons, declining to 50 gallons by 2030.
As for the Upper Basin, states continue to push not for water conservation but for more dams and reservoirs that would drain water from the basin, such as the proposed St. George, Utah, Diversion from Lake Powell. John Fleck, Director of the water resources program at the University of New Mexico said, “it’s not a binary question of: Is there enough water? The way we need to think is that the system is at risk, and every time you take more water you create risks for existing users.”
Meanwhile, California is king of the Colorado River and wants you to know it.
“We’ll never give up that right – our first priority among all Colorado River water users — and never say we’ll give up that right,” Hassencamp told me. “ That’s our fallback position, though we’ll set it aside for now and try to work out a solution.”
For Colorado, Utah, Wyoming and New Mexico, this is a clear warning. As Hassencamp put it: “We recognize the pie is shrinking for good.”

Risk of severe water shortages in the seven-state Colorado River Basin have risen dramatically since April with new forecasts indicating that lakes Powell and Mead could hit crisis levels much sooner than previously expected.
U.S. Bureau of Reclamation Commissioner Brenda Burman said the change in the forecast is noteworthy.
“We’re dealing with more uncertainty than we thought,” she said during a virtual press conference Tuesday.
The Bureau of Reclamation is responsible for managing the two storage vessels and monitoring the mountain snowpack and runoff that feeds them every year.
As recently as April, when the last forecast came out, inflows to Lake Powell were projected to be roughly 75 percent of average this year. The latest report, however, indicates inflows will be just 55 percent of average.
In just five months, the risk that reservoir levels could fall low enough by 2025 to threaten power generation and the ability to release physical water to downstream users has risen 12 percent, according to Reclamation.
Carly Jerla, a hydrologist and water modeling expert, runs the modeling team for Reclamation’s Lower Basin operations.
The 21-year stretch of drought in the Colorado River Basin has made the system extremely vulnerable to changes in weather patterns, Jerla said.
“In this system, one year of poor hydrology can influence the ways these reservoirs are impacted for multiple years into the future,” she said.
Reclamation officials stopped short of saying how states should respond to the dire water supply predictions.
Seven U.S. states share water from the Colorado River Basin. These include Colorado, Wyoming, New Mexico and Utah in the Upper Basin, and Arizona, California and Nevada in the Lower Basin. Mexico also relies on the river’s flows.
The two regions in the U.S. are governed separately, with the Upper Basin states overseen by the Upper Colorado River Commission and the Lower Basin overseen by the Bureau of Reclamation.
The river is a major source of water in Colorado, where it supplies roughly half of the drinking water on the Front Range and irrigation water for ranches, fruit orchards and corn fields on the Western Slope and Eastern Plains.
Brad Wind is general manager of Northern Water. It serves cities and farms from Boulder to Greeley and is one of the largest water providers in the state. Wind said the rising risk levels aren’t that surprising.
But, he said, to help the drought-stressed system regain some semblance of balance will require much more work. “We can’t walk away from this.”
Last year, for the first time in history, the seven states agreed to adopt a basin-wide Drought Contingency Plan. The Lower Basin component of that plan is now complete and requires cutbacks in water use as levels in the reservoirs fall and reach certain elevations. Arizona has already had to cut back its water use in 2020 as a result of the agreement, and Mead’s levels have risen as a result of these actions and other conservation programs. Now at 44 percent full, the reservoir is the highest it’s been in six years, according to the Bureau of Reclamation.
But the Upper Basin, though it has agreed to big-picture elements of an Upper Basin plan, has more work to do to define how a major piece of that plan involving large-scale water conservation, called demand management, would work.
Rebecca Mitchell is director of the Colorado Water Conservation Board, the agency managing the demand management study process in Colorado. She also serves on the Upper Colorado River Commission, representing Colorado. In a written statement, she said the 2019 Drought Contingency Plan has provided additional security for the system and that the study will move forward even as conditions on the river worsen.
“Colorado will continue to track the hydrologic conditions, and work collaboratively with the other basin states,” she wrote.
With the new forecast, however, pressure to cut back water use is rising.
Since 2000, lakes Powell and Mead have lost nearly half of their stored water supplies. Back then the system was nearly full, at 94 percent, according to Reclamation. This year the two reservoirs are collectively projected to end what’s known as the water year, on Sept. 30, at just 53 of capacity.
Climate change and warmer temperatures continue to rob the river of its flows. In fact, water flowing into Lake Powell during that 20-year period was above average just four out of the past 19 years, according to Reclamation.

FromThe Associated Press (Sam Metz) via The Durango Herald:
After a relatively dry summer, the U.S. Bureau of Reclamation released models this week suggesting looming shortages in Lake Powell and Lake Mead – the reservoirs where Colorado River water is stored – are more likely than previously projected.
Compared with an average year, only 55% of Colorado River water is flowing from the Rocky Mountains down to Lake Powell on the Utah-Arizona line. Because of the below-average runoff, government scientists say the reservoirs are 12% more likely to fall to critically low levels by 2025 than they projected in the spring.
“This is a pretty significant increase over what was projected in April due to the declining runoff this year,” hydrologist Carly Jerla said.
The forecast could complicate already-fraught negotiations between Arizona, California, Colorado, New Mexico, Nevada, Utah, Wyoming and Mexico over future shares of the river that supply their cities and farms. Those talks will draw up new agreements by 2026 about use of the river that’s under siege from climate change and prolonged drought.
Some urban and agricultural water users have been forced to conserve water to secure the river long term, but it remains overtapped. And as cities like Phoenix and Las Vegas keep growing, the region is only getting thirstier.
“We know that warmer temperatures have contributed to the drought of the last 21 years, and we know that they have exacerbated it,” Bureau of Reclamation Commissioner Brenda Burman said.
Unlike the 24-month projections that the agency uses to allocate water to the seven states and Mexico, the models released Tuesday simulate various weather and usage patterns to help water users prepare for different scenarios.
Scientists use what’s called the Colorado River Simulation System to project future levels of the two reservoirs. They employed “stress testing” techniques based on river flows since 1988 to determine potential shortages if drought conditions persist.
Arizona, Nevada and Mexico agreed to cuts for the first time under a drought contingency plan signed last year. The water level in Lake Mead sits at 1,083 feet. When projections drop below 1,075 feet, Nevada and Arizona will face deeper cuts mandated by the plan.
Stress test models suggest a 32% chance Lake Mead will fall below 1,075 feet by 2022 and a 77% chance by 2025. The model’s median estimates indicate Lake Mead will drop by 35 feet by 2026.
The water level in Lake Powell is at 3,598 feet, and estimates suggest it could drop by 50 feet by 2026.

Western water in-depth: Major science report that highlights scientific shortcomings and opportunities in the basin could aid water managers as they rewrite river’s operating rules
Practically every drop of water that flows through the meadows, canyons and plains of the Colorado River Basin has reams of science attached to it. Snowpack, streamflow and tree ring data all influence the crucial decisions that guide water management of the iconic Western river every day.
Dizzying in its scope, detail and complexity, the scientific information on the Basin’s climate and hydrology has been largely scattered in hundreds of studies and reports. Some studies may conflict with others, or at least appear to. That’s problematic for a river that’s a lifeline for 40 million people and more than 4 million acres of irrigated farmland.
From the Upper Basin states of Colorado, Wyoming, New Mexico and Utah to the urban centers of Arizona, Nevada and California in the Lower Basin, water managers depend on that science to guide their decisions. More than ever, as those managers grapple with a hotter, drier Colorado River Basin and growing demand for a shrinking resource, they need an accessible scientific handbook as they get ready to draft a new set of rules for managing the river.
A new report synthesizes that science and puts it into context. Titled Colorado River Basin Climate and Hydrology: State of the Science, the report released earlier this year draws from about 800 peer-reviewed studies and agency reports on crucial topics – weather, streamflow, historical hydrology and climate change – to help navigate the future of river management. It doesn’t provide answers but offers a technical manual of sorts for a river system so vital to the Southwestern United States and Mexico.
“It’s attempting to create that two-way dialogue, but to do so in a way that water managers aren’t having to go and read 20 different reports,” said Colby Pellegrino, deputy general manager of resources with the Southern Nevada Water Authority, which helped fund the report. “It’s a fabulous tool in that [it] is one guiding document to look at if you want to increase your understanding.”
Written by a veteran cadre of more than a dozen scientists and engineers, it pulls no punches in describing a river system in peril.
“The average conditions, over time and across the basin, suggest a (barely) sufficient supply and, by smoothing out the variability, mask existing and prospective shortages,” says the report, produced through the Western Water Assessment, an interdisciplinary research program based at the University of Colorado, Boulder.
The report notes that the ultimate aim of integrating new research into practice is to produce more accurate short- and mid-term forecasts of runoff and more meaningful long-term projections of expected water supply.
“The future is and always has been uncertain,” said Jeff Lukas, research integration specialist with the Western Water Assessment and co-lead author of the report. “Now, at a time in which the Basin’s water supply and depletions are in delicate balance at best, system storage is half-full, and climate change is increasingly impacting hydrology, these forecasts and projections have become even more critical.”
Improving Forecasting Tools
Funded by the Bureau of Reclamation and its partners in the seven Western states that depend on the river, the report emphasizes the need to improve hydrologic forecasts, projections and predictive tools in the Colorado River Basin, all the while acknowledging the need for resilience.
“There is not now, and likely never will be, perfect weather and climate data,” the report says. “Producers of climate information need to communicate, and users should be cognizant of, the strengths and weaknesses of the data they choose and how climate data choices influence their conclusions.”
Terry Fulp, regional director of Reclamation’s Lower Colorado Region, said the report emphasizes that Colorado River Basin hydrology is increasingly volatile and must be planned for accordingly.
“This made it very clear that we can’t rely on the 100-year record,” he said. “You can’t just look at the past and assume it’s replicated in the future. We all knew that, but it is good to have the body of science conclude that, too.”
Brad Udall, a senior climate and water research scientist at Colorado State University who was a technical reviewer for the report, said that while it covers an amazing breadth of material, it has key advice for water managers.
“At the broadest level, the take-home message is, a tremendous amount of science has been done in the Basin,” he said, “and while it may not give us the answers that tell us what to do, it strongly suggests we need to be prepared for a very different kind of future that’s hotter and drier.”
The past 40 years have seen a substantial warming trend, the report says, noting that the period since 2000 has been about 2 degrees Fahrenheit warmer than the 20th-century average and likely warmer than at any time in the past 2,000 years.
Authors of the State of the Science report note they did not evaluate current Basin water management, address ecosystem needs or provide recommendations. Instead, they concentrated on assessing the chain of data and models that provide an understanding of the Basin’s hydrology, while recognizing how the rapid expansion of scientific knowledge and its increasing complexity parallel the growing uncertainties about how future climate will affect hydrology. Absent a dramatic increase in rain and snow, the Basin’s runoff and water supply are increasingly being affected by warmth.
With temperature, there is “a very clear signal and that trend … is significant enough that people have a fair amount of confidence it is impacting the hydrology in the Basin,” said lead co-author Liz Payton, Western Water Assessment’s Colorado River Basin assessment specialist.
Those effects were evident this year as a warm spring quickly erased what had been a robust snowpack leading up to April 1.
“I’m still stunned by the 100 percent snowpack and the 52 percent runoff,” Udall said. “That’s just mind-boggling.”
Adding the Climate Change Factor
The State of the Science report comes at an important time. Fresh from completing unprecedented Drought Contingency Plans in 2019, key players in managing the river will next turn their attention to updating and renegotiating the river’s 2007 Interim Operating Guidelines, which expire in 2026. Crafted in the early stages of a two-decade drought, the 2007 guidelines along with the subsequent Drought Contingency Plans are a testament to managing the Basin’s extreme volatility.
Coming to terms on a new set of guidelines, including their length, will differ from 2007 because the last set of guidelines was based on limited modeling data that didn’t fully incorporate climate change projections, said Bill Hasencamp, manager of Colorado River resources with the Metropolitan Water District of Southern California.
While it is hard to predict specifically how the science report will inform the renegotiations, its recurring themes of increased temperatures, reduced streamflow and variable precipitation “will almost certainly arise in the context of the modeling efforts undertaken in the renegotiation,” said Amy Haas, executive director of the Upper Colorado River Commission.
New revelations about Colorado River Basin science appear with increasing frequency. In a lengthy July thread on Twitter, Udall noted the growing footprint of climate change in the Basin and how the expected pace of warming, which some models project could be as much as 5 degrees Fahrenheit by 2050, would greatly amplify the impacts seen in 2020. Scientists with the U.S. Geological Survey this year said warmer temperatures by 2050 could reduce the amount of water flowing in the river by as much as 30 percent.
“All of this has a name: aridification,” Udall wrote on Twitter. “Get used to it.”
The State of the Science report helps water managers understand key subjects, such as what climate monitoring is revealing and where uncertainty and errors exist.
Report contributor Carly Jerla, who manages Reclamation’s Modeling & Research Group, called it a “no-nonsense” scientific platform with a clear message. “We know we can’t just let history repeat itself,” she said. “This report clearly lays out that something else has to be done.”
Pellegrino, with Southern Nevada Water Authority, said the report provides a “one-stop shop” for busy river managers.
“Of all the many hats water managers wear, we are not researchers and we are not innovators,” she said. “It’s difficult to have an eye on all of the things we are doing related to species and policy and water supply planning and also be able to comb through the various sources of new hydrologic or climate change data.”
Like many, Pellegrino would prefer a consistent pattern of climate and water supply projections from which to base management decisions.
“It’s really hard for somebody who wants predictability to acknowledge there is going to be wide range of variability that’s going to persist for a very long time,” she said. “But that’s where we are.”
The State of the Science report stems from the 2017 Colorado River Hydrology Research Symposium aimed at giving water resource managers a better understanding of new hydrologic research initiatives, and giving researchers a better understanding of the Basin water system and the tools used by managers. Together, they explored how research could help improve those tools. That was crucial because research not fully grounded in the particulars of the managed system can produce alarming results. Hasencamp recalled one study that gave Lake Mead an even chance of going dry by 2021, a finding that dumbfounded water managers.
“We all looked at it and said, ‘What assumptions are they making?’” he said. “This is not very good science because they didn’t talk to the people who are actually running the system and managing it.”
Reaching Consensus on Science
The historical record illustrates the dramatic swerves in Colorado River Basin hydrology. Some years the snow never stops. Other times, unseasonable warmth and dryness dominates as officials nervously watch lake levels plummet in the river’s two major reservoirs, Lake Powell and Lake Mead.
Scientists devote their careers to figuring how forecasts and projections can improve. On the ground, life can be more stressful for water resource practitioners charged with providing a reliable water supply. Report authors acknowledge the conundrum.
“Given the stakes involved, it is reasonable that Colorado River Basin planners and managers desire greater certainty in water supply forecasts and long-term projections,” the report’s authors wrote. “They need some sense of the likelihood of hydrologic shifts, especially shifts to the dry side.”
One area of possible improvement is the 24-month water supply forecasting system that is partly based on assumptions of average monthly inflows to the Colorado River between Lake Powell and Lake Mead, said Payton.
“That’s a significant reach because if there is a lot or not as much inflow as the monthly average, you could shift Lake Mead above or below one of the important thresholds” that determine how much water agencies can draw from the river, she said. “If Mead is right at a shortage threshold and you have underestimated the inflow, you may end up declaring a shortage when you didn’t have to.”
Improvements in forecasting are needed from months to years to even decades out, said Pellegrino, with Southern Nevada Water Authority.
“Obviously, the long-term time scale is probably the most relevant for policy decisions, but the short and mid-terms are just as important,” she said. “The question is, if we knew next year was going to repeat the hydrology we saw in 2002, the driest year on record, would we make different water management decisions? I think the answer to that is yes at all time scales.”
Faced with uncertainty, Pellegrino believes the prudent approach is to be “eyes wide open” to the implications of the wide range of variability.
“Instead of identifying the hydrology that’s problematic or exact streamflow record that’s correct, spend your efforts coming up with the benchmarks for your water management community or basin that really mean something,” she said.
Making Better Decisions
For an area such as Las Vegas, that means preparing for more heat and dryness. Pellegrino said her agency has calculated that the creeping temperature rise could increase per capita water use by nine gallons a day by 2035.
Outcomes like that mean agencies should prepare for as many scenarios as possible, aiming for maximum flexibility, “like a dimmer switch,” said Taylor Hawes, Colorado River program director with The Nature Conservancy. Waiting too long to act could be costly.
“We should consider this time before a full-blown crisis as a gift,” she said. “We are on ‘water time,’ and developing new water management tools takes years. We should not squander this time now, because we will never have a perfect picture of what the next year or two holds. Trying to develop these kinds of tools in the middle of the crisis will create chaos, social and economic impacts and unintended consequences. It is much more effective to have the tools ready to deploy before they are needed.”
Fulp, Reclamation’s regional director, said the report helps reframe the basis for near-term planning and gives a glimpse of what to expect further out, uncertainty and all.
“You’re talking about looking at hundreds, if not thousands of different futures and seeing what the statistics tell us,” he said. “Is one decision better under a lot of scenarios or is it only better under a few scenarios?”
The flow of scientific data about the Colorado River Basin will continue. Some reports will generate more response than others. Amid that, the depth and breadth of the Colorado River Basin Climate and Hydrology: State of the Science stands out.
“We hear about so many studies with dire predictions for the Colorado River but I think the bigger meta message is we have this great collaboration among water agencies to gather more information about the past, present and future of climate hydrology to make better decisions and planning,” said Lukas, with Western Water Assessment. “That’s the story I like to emphasize.”

The six Colorado River Basin states that do not have the letters “U-T-A-H” in their names just sent a remarkable letter to Secretary of the Interior David Bernhardt with a plea – don’t let the rush toward federal approval of Utah’s proposed Lake Powell Pipeline blow up the Colorado River Basin’s framework of collaborative rather than confrontational problem solving:
The six-state letter, the product of intense discussions in recent weeks among the states (including the one with “U-T-A-H” in its name) takes great pains to point to an important historical norm in Colorado Basin governance – states don’t mess in other states’ internal water use decisions. But in asking to move Upper Basin water to a Lower Basin community, Utah has crossed a line that the other states simply couldn’t let pass.
A study by the Bureau of Reclamation predicts that the current water levels in the Colorado River Basin will only postpone water shortages.
The study found that water levels in western reservoirs this year are similar to the past few years. John Berggren, a water policy analyst at Western Resource Advocates, said the overall trend in water levels over the past 30 years has been downward.
Because water levels have been in decline, Berggren said one good snow year is not enough to replenish the reservoirs. He said this year will only postpone water shortages by a few years…
Berggren said dry soil, warmer air, and earlier blooms use up more water that doesn’t end up in the reservoirs.

State regulators in the Yampa River basin say most water users are now willingly complying with an order to measure how much water they are taking — an order once greeted with suspicion and reluctance. But challenges to compliance remain, including the cost of installing equipment.
Last fall, the Colorado Division of Water Resources ordered nearly 500 water users in the Yampa River basin to install measuring devices to record their water use. Nearly a year later, most of those water users are embracing the requirement, according to water commissioner Scott Hummer.
“I am fully confident that over 90% of the people who have orders pending have either complied, are in the process of complying or have asked for an extension,” Hummer said. “So we are getting the cooperation and buy-in that we are requesting from our water users. They are understanding why we are doing it, at least in my area.”
Hummer is the water commissioner for Water District 58, which spans 400 square miles and includes all the water rights above Stagecoach Reservoir. He oversees between 350 and 400 diversion structures.
Measuring water use is the norm in other river basins, especially where demand outpaces supply. But the tightening of regulations is new to the Yampa River basin, and the order was initially met with resistance from some ranchers.
John Raftopoulos, whose family ranches along the Little Snake River, a tributary of the Yampa in Moffat County, said he thinks most irrigators are complying. His cattle ranch has about 15 measuring devices, and he has to install a few more to be completely compliant.
“I know (the state) has to use them. There’s no other way they can control the water; they’ve got to have the measuring device,” Raftopoulos said. “You just got to bite the bullet and install them.”
State law requires water users to maintain measuring devices on their canals and ditches, but this rule was not enforced in Division 6 — consisting of the Yampa, White, Green and North Platte river basins — because historically there was plenty of water to go around in the sparsely populated northwest corner of the state. Long seen as the last frontier of the free river, there has been little regulatory oversight from the state when it came to irrigators using as much water as they needed. But that changed in 2018 with the first-ever call on the river.
A call is prompted when streamflows are low and a senior water rights holder isn’t receiving their full amount. They ask the state to place a call, which means upstream junior water rights holders must stop or reduce diversions to ensure that the senior water right gets its full amount.
Although the order for a measuring device comes with a deadline and the threat of fines, Division 6 engineer Erin Light has been lenient with water users and willing to give them extra time to get into compliance. The process to request an extension is simple: A water user can simply email Light.
“If a water user is working with our office, we are not going to go shut their headgate off,” she said. “We are going to work with them.”
Light doesn’t have an exact count on how many water users have complied so far — water commissioners are working in the field this summer and haven’t had time to enter the most current information into the division’s database yet — but as of January, the Yampa had 49% compliance.
“I am not hearing anything (from water commissioners) about concerns of noncompliance. If there were problems, they would let me know,” Light said. “I have a fair amount of confidence that things are going well in all my areas as to compliance.”
Still, some worry that the cost of installing the devices — which in most cases are Parshall flumes — is too big a financial burden for some water users. The devices, which channel diverted water and measure the flow below the headgate, can cost thousands of dollars, which adds up for water users who need to install multiple devices.
The Upper Yampa Water Conservancy District and the Yampa-White-Green Basin Roundtable have teamed up in recent months to create a $200,000 grant program to help water users with infrastructure-improvement expenses. According to Holly Kirkpatrick, the communications manager for the conservancy district, water users so far have completed about $3,500 worth of work. That money will be reimbursed through the grant program.
“We expect to see a huge influx of applications as the season comes to an end,” she said.
In March, Light issued notices to water users in the other Division 6 river basins — White and Green — but decided to delay sending orders after talking with some who had concerns over the economic crisis caused by the COVID-19 pandemic.
In a June letter to Light, signed by four water conservancy districts — White River, Rio Blanco, Yellow Jacket and Douglas Creek — representatives said they would be interested in seeking opportunities for financial assistance for their water users. Under the best-case scenario, it would take until spring to secure grant money and begin installing devices, the letter said.
“This year is a tough year to try and ask people to do anything above and beyond what they already have to do,” said Callie Hendrickson, executive director of the White River and Douglas Creek Conservation Districts. “I know (Light is) willing to give extensions, but right now, our folks don’t need that additional financial or emotional stress.”
