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.

The New Mexico Interstate Stream Commission and The Nature Conservancy hope to demonstrate that the strategic water reserve can help endangered fish recover while also providing the ability to meet water compact requirements in the San Juan Basin.
The Interstate Stream Commission approved allowing ISC Director Rolf Schmidt-Petersen to continue negotiations with the Jicarilla Apache Nation to lease up to 20,000 acre feet of water annually that became available as it is no longer needed for operation of the San Juan Generating Station.
The Jicarilla Apache Nation acquired rights to water stored in Navajo Lake in 1992 and has the authority to lease this water to other entities to help the tribe. Up until recently, the nation has leased water to Public Service Company of New Mexico to operate the San Juan Generating Station.
But the potential of the power plant closing in 2022 as well as a reduction in the amount of water needed to operate it due to the closure of two units in 2016 means that this water is now available for the state to potentially lease.
The water would be placed in the strategic water reserve, which has two purposes: assisting with endangered species recovery and ensuring the state meets its obligations under water compacts. When needed, the water could be released from the reservoir to help with the fish or to meet the requirements of the 1922 Colorado River Compact…
Terry Sullivan, the state director of The Nature Conservancy in New Mexico, said the organization has been working on the San Juan River for 15 years trying a variety of restoration projects to help create habitat. The fish rely on slow backwaters for reproduction…
Sullivan said the water lease is a great step forward to achieve both compact requirements and benefits to endangered species.
The amount leased each year would depend on funding available. One of the details of the lease agreement that has not yet been determined is the price…
Peter Mandelstam, the chief operating officer for Enchant Energy, said in a statement that the company believes it has enough water rights without the Jicarilla Apache lease to successfully retrofit the San Juan Generating Station with carbon capture technology and operate it.
In response to decreasing tributary flows, the Bureau of Reclamation has scheduled an increase in the release from Navajo Dam from 300 cubic feet per second (cfs) to 350 cfs on Saturday, November 21st, starting at 4:00 AM. Releases are made for the authorized purposes of the Navajo Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the San Juan River (Farmington to Lake Powell).
The San Juan River Basin Recovery Implementation Program recommends a target base flow of between 500 cfs and 1,000 cfs through the critical habitat area. The target base flow is calculated as the weekly average of gaged flows throughout the critical habitat area from Farmington to Lake Powell.
Utah State Engineer Teresa Wilhelmsen has rejected a controversial proposal to divert 55,000 acre-feet of the Green River’s flow from Utah to Colorado’s fast-growing Front Range cities.
Colorado entrepreneur Aaron Million has been pursuing this idea for more than a decade, resurrecting his pipeline proposal in 2018 after two prior failed attempts at approval. This time his firm White Horse Resources proposed a scaled-down pipeline tapping the Green below Flaming Gorge Dam at Browns Park and running 325 miles underground to Denver. Dubbed the “Green Sun Storage Hydro Power Project,” it would generate hydropower along its 3,800-foot decent from the Continental Divide to the Front Range.
Wilhelmsen found the proposal ran counter to policies Utah has been pursuing for decades regarding the recovery of endangered species of fish and the Beehive State’s own interest in developing its share of water in the Colorado River system…
Meanwhile, Wilhelmsen is considering Utah’s own proposal to substantially alter an 86,000-acre-foot water right associated with Flaming Gorge, moving the point of diversion downstream to feed the proposed Lake Powell Pipeline.
At a hearing before the state engineer two years ago, Million likened his project to the 140-mile pipeline across southern Utah to St. George, claiming there was sufficient flows in the Green to accommodate both diversions.
The Federal Energy Regulatory Commission has previously twice turned down similar Green River diversions proposed by Million.
“This [latest] decision is a big win for the Green River as well as the people and endangered fish that depend on it,” said Taylor McKinnon, a senior campaigner at the Center for Biological Diversity. “We hope the state engineer’s decision is the final nail in the coffin of this absurdly greedy, irresponsible plan.”
Diverting the water at Browns Park would have undermined costly efforts underway to rescue some of the Green’s native fish, McKinnon and other environmentalists argued.
Commissioners want to measure the potential impact of Nestlé’s proposal to pump, truck and bottle up to 65 million gallons of water a year.
After several meetings in the last two months featuring hours of public input — virtually all of it opposing the plan — and executive session discussions with attorneys, the county’s three-member board of commissioners on Tuesday announced a plan to hire an economic analysis firm to study the economic impacts of the water-pumping proposal.
“I want to make the best decision I can with just three people here trying,” Commissioner Greg Felt said on Nov. 10 as he floated the idea of hiring an economist to study Nestlé’s request for a 10-year permit to pump and bottle water from a network of wells on the Arkansas River.
Nestlé, the world’s largest food and beverage company, began drawing water from the valley in 2009 as part of a 10-year permit. That permit allowed the company to drill wells, build a pipeline and truck water to Denver for bottling under the Arrowhead brand. The company acquires water from the Upper Arkansas River Water Conservancy District every year to augment flows in the river and replace its removal of groundwater.
Last year the company asked for a permit renewal and, after pandemic delays, the county began studying the request in October. Chaffee County’s commissioners have heard from dozens of residents that a lot has changed in the decade since Nestlé first arrived…
Nestlé earlier this year announced a plan to replenish all the water it sucks from watersheds and offset the carbon impact of bottling and transporting water. That “zero environmental impact” sustainability plan was followed by news that the international conglomerate was exploring the sale of bottling operations in the U.S. and Canada. The possibility of a sale troubled Chaffee County commissioners. The board drafted new permit rules that, if approved, would require local approval of a new owner to operate under the Nestlé permit.
Nestlé Waters North America was amenable to the new requirement. And the company earlier this month, in response to local input, crafted new conditions for the permit that would direct more Nestlé money into the local community…
The new conditions divide the company’s contributions to the county into two tiers based on how much water is extracted for bottling.
When the company pumps less than 125 acre-feet, or roughly 41 million gallons a year, the school districts in Buena Vista and Salida would get $15,000 a year for the length of the 10-year contract and up to $10,000 more a year for each school district depending on matching funds…
The commissioners will meet again on Dec. 8 to discuss a contract with an economic advisory group — the cost of which will be covered by Nestlé Waters North America — as well as the possible extension of the company’s permit during the analysis.
The U.S. Geological Survey is in the beginning stages of learning more about this river via an expanded and more sophisticated monitoring system that aims to study details about the snowpack that feeds the river basin, droughts and flooding, and how streamflow supports groundwater, or vice versa.
Begun earlier this year, the probe is part of a larger effort by the federal agency to study 10 critical watersheds throughout the country by expanding its monitoring capabilities.
According to the research agency, it maintains real-time monitors that provide data on the nation’s water resources, including more than 11,300 stream gauges that measure surface-water flow and/or levels; 2,100 water-quality stations; 17,000 wells that monitor groundwater levels; and 1,000 precipitation stations.
While that may seem like a lot, the network falls short of meeting the demands of modern-day analysis. The monitors in place cover less than 1% of the nation’s streams and groundwater aquifers and were designed to meet the needs of the past, according to the agency.
Because of this, the agency is investing in the Next Generation Water Observing System, which will tap sophisticated new monitoring capabilities resulting from recent advances in water science.
The effort will also bring together the knowledge and expertise of agency scientists, resource managers and other stakeholders to determine water information needs not only now, but into the future.
The system will use both fixed and mobile equipment — including drones — to collect data on streamflow, evapotranspiration, snowpack, soil moisture, water quality, groundwater/surface-water connections, stream velocity distribution, sediment transport and water use.
When it comes to the Colorado, understanding snowpack is critical because the Upper Colorado River Basin supplies about 90% of the water for the entire Colorado River Basin — with about 85% of the river flow originating as snowmelt from about 15% of the basin at the highest altitudes.
The lower basin is arid and depends upon that managed use of the Colorado River system to make the surrounding land habitable and productive.
“New monitoring technology is essential to addressing many issues associated with our annual water balance in the Upper Colorado River Basin,” said Dave “DK” Kanzer, who is deputy chief engineer at Colorado River Water Conservation District.
FromThe Associated Press via The Kearney Star-Herald:
Todd Siel with the Lower Republican Natural Resources District said he expects the state will be able to meet the terms of the Republican River compact next year without putting additional restrictions on irrigation or pumping additional water into the basin.
Siel told the Kearney Hub that Harlan County Lake is still mostly full thanks to the extremely wet weather of 2019, and that is a major factor in helping Nebraska comply with the river pact next year.
The Republican River Compact allocates the waters of the basins between the states of Colorado, Nebraska and Kansas.
Nebraska, Kansas and Colorado have fought for decades over water entitlements provided under the compact. The compact has resulted in lawsuits among the states, which regulate access to the water.
The compact signed in 1943 gives Nebraska the rights to 49 percent of the river’s water, while Kansas receives 40 percent and Colorado gets 11 percent. The Republican River originates in Colorado, crosses the northwestern tip of Kansas into Nebraska, then runs through Nebraska before re-entering Kansas through its northeastern corner.
The Next Generation Water Observing System provides high-fidelity, real-time data on water quantity, quality, and use to support modern water prediction and decision-support systems that are necessary for informing water operations on a daily basis and decision-making during water emergencies. The headwaters of the Colorado and Gunnison River Basin provide an opportunity to implement the NGWOS in a snowmelt-dominated system in the mountain west.
The USGS Next Generation Water Observing System (NGWOS) is generating integrated data on streamflow, groundwater, evapotranspiration, snowpack, soil moisture, water quality, and water use. When fully implemented, the NGWOS will intensively monitor at least 10 medium-sized watersheds (10,000-20,000 square miles) and underlying aquifers that represent larger regions across the Nation.
The USGS has selected the headwaters of the Colorado and Gunnison River Basin (Upper Colorado River Basin) in central Colorado as its second NGWOS basin. This decision was based on rigorous quantitative ranking of western basins, input from USGS regions and science centers, and feedback from targeted external stakeholders in the west.
The Upper Colorado River Basin is important because nearly all flow in the Colorado River originates in the upper basin states and runoff from the Upper Colorado River Basin is nearly three times that of other basins in the area. Thus, the Upper Colorado River Basin is particularly critical for downstream users.
Long-term drought conditions facing the Upper Colorado region, interstate ramifications of the drought, water-quality issues, stakeholder support, and alignment with Department of Interior and USGS priorities make the Upper Colorado an ideal basin to implement the USGS’s integrated approach to observing, delivering, assessing, predicting, and informing water resource conditions and decisions now and into the future. Of note, a newly released (October 2019) Federal Action Plan for Improving Forecasts of Water Availability includes a milestone to pilot long-range water prediction in the Upper Colorado River Basin, an activity that will greatly benefit from the newly selected USGS NGWOS basin.
An integrated data-to-modeling approach in the Upper Colorado River Basin will help improve regional water prediction in other snowmelt dominated systems in the Rockies and beyond. The approach is useful for addressing issues of both water availability and water quality and for evaluating the effects of both short-term climate perturbation (for example, fire, insect mortality, drought) and long-term climate change.
Water Resources Challenges in the Colorado River Basin
The Colorado River supplies water for more than 40 million people and nearly 5.5 million acres of farmland across the western United States and Mexico. The Colorado River and its main tributaries originate in the mountains of western Wyoming, central Colorado, and northeastern Utah. The large amount of snowmelt that feeds the Upper Colorado is central to water availability throughout the Basin. In 2019, urgent action was required to prevent previously developed rules from potentially reducing Colorado River water allocations to Arizona, Nevada and Mexico due to declining water levels in the two largest reservoirs within the Colorado River Basin—Lake Powell and Lake Mead. A Colorado Drought Contingency Plan was signed in April 2019.

…city leaders say they are increasingly frustrated by Larimer County’s unwillingness to let them build a critical pipeline that would carry the water from the Cache La Poudre River near Fort Collins to Thornton — so much so that they have started alerting developers that the city may have to stop issuing building permits.
The new language warns that “the City does not guarantee capacity in its water or wastewater systems for proposed or future developments.”
Among the projects at stake for the state’s 6th largest city is dense multi-family housing planned around new N-Line rail stations that just went operational in September.
That’s frustrating to Thornton Mayor Jan Kulmann, who points to the thousands of acre-feet of water the city owns free and clear in the Cache La Poudre River northwest of Fort Collins — water rights it purchased more than three decades ago…
The answer goes back to February 2019, when the Larimer County commissioners unanimously voted to deny Thornton a permit for a 72-mile-long pipeline the city wants to install to carry that water to this suburb of 140,000. Jeff Coder, Thornton’s deputy city manager of city development, said the denial essentially holds Thornton’s growth plans “hostage.”
The city has enough water in its portfolio to supply 5,000 additional housing units, he said, or approximately 160,000 residents. The city’s long-term vision is for a population of 240,000 by 2065.
While no builders have pulled out of the city, Coder said, that day may not be far away. Maybe as soon as 2024 or 2025, he said.
“It’s understandably creating a great deal of concern,” he said. “In fairness to those who are making significant investments in our community, we don’t want someone who has gone through the approvals process expecting to get a building permit to have us at the last minute tell them we can’t because of this water issue.”
We want to prepare people for a worst-case scenario.”
The obvious solution, [Gary Wockner] said, is for Thornton to let its water flow down the Poudre through Fort Collins — “use the river as a conveyance” — and take it out further downstream near Windsor, obviating the need for a $450 million pipe that will require trenching and burial across 26 miles of Larimer County…
The city counters that allowing its share of water to flow through Fort Collins — and past several water treatment facilities — would severely degrade its quality and cost the city dearly to clean it. Emily Hunt, deputy infrastructure director for Thornton, said the river option was merely one of a number of alternatives the city put on the table as it was firming up plans to access its water.
“We specifically picked a site that was above urban impacts and the price we paid reflected that,” she said. “If we wanted a low-quality source that we clean up later, we could have done that and paid less money.”
According to the city, Thornton paid $578 million for 289 shares of water and storage rights in the Poudre River, along with $92 million for more than 18,000 acres of farmland in Larimer and Weld counties, where it has been sending its Poudre shares by ditch over the last 30 or so years.
But that level of investment wasn’t enough to sway the commissioners in Larimer County last year.
Outgoing Commissioner Steve Johnson said then that the proposed 48-inch diameter pipe, which would run across the northern edge of Fort Collins to Interstate 25 before turning south toward Thornton, ranked as one of the most contentious issues he had ever seen raised in the county.
But just this past September, the same commissioners voted 2-1 to approve a 1041 permit for the Northern Integrated Supply Project, a controversial $1.1 billion water storage initiative that would create Glade Reservoir northwest of Fort Collins and a second reservoir out on the eastern plains.
It also involves several water pipelines running through Larimer County.
Thornton recently included the NISP approval in its court filings appealing Larimer County’s denial of its pipeline project, citing it as evidence that the commissioners’ 2019 decision was “arbitrary and capricious.”
According to the U.S. Department of Agriculture National Water and Climate Center’s snowpack report, the Wolf Creek Summit, at 11,000 feet of elevation, had 8.1 inches of snow water equivalent as of 2 p.m. on Nov. 11.
That amount is 169 percent of the Nov. 11 median for the site.
The San Miguel, Dolores, Animas and San Juan River Basins were at 148 percent of the Nov. 11 median in terms of snowpack.
With more winter storms rolling through Pagosa Springs and the surrounding areas, the San Juan River flow spiked to over 300 cfs on Nov. 8. As of 2 p.m. on Nov. 11, the river flow at the U.S. Geological Survey station in Pagosa Springs was listed at 58.1 cfs.
Based on 84 years of water records, the average flow rate for this date is listed at 99 cfs.
The highest recorded rate for this date was in 1987 at 340 cfs. The lowest recorded rate was 13 cfs, recorded in 1951.
From the San Juan Water Conservancy District (Al Pfister) via the The Pagosa Daily Post:
As is custom and per State procedures, the San Juan Water Conservancy District (SJWCD) is in the process of developing our 2021 budget.
Our draft 2021 budget sets the framework for our activities in the coming year. In an effort to better communicate with our district taxpayers as to how we can provide the appropriate amounts of water under wet and drought conditions, we are inviting you to a public meeting and hearing on November 16, 2020 at 5:00pm via ZOOM to discuss our proposed 2021 budget.
We have developed our proposed 2021 budget to be used to set the framework for activities that we will implement in the accomplishment of our mission. Our mission is to ensure water resources are available for beneficial use to those who do provide water (such as the Pagosa Area Water and Sanitation District) for the community. This may come in the form of consumptive uses like agriculture, municipal, fire protection, and industrial pursuits. This may also mean non-consumptive uses such as recreational, wildlife habitat, and aesthetics.
Our main focus with the 2021 budget will be implementation of our Strategic Plan that will deal with the challenge of serving the water needs of the majority of Archuleta County. We look forward to seeing and hearing from you on November 16. If you would like more information or want to discuss the budget and associated issues, please contact me or any board member whose contact info is listed on our website — http://www.sjwcd.org — under the “About Us” tab. The website also has the draft 2021 budget, our draft Strategic Plan, the meeting agenda, and the ZOOM information.
Accomplishment of our mission must take place in accordance with Colorado water law (including the prior appropriation doctrine), and following the direction set forth in the Colorado State Water Plan.
The Colorado Water Plan (Plan) was completed in 2015 and is based on three foundational elements: interstate compacts and equitable apportionment decrees (ie. each of the States are entitled to a certain amount of water as detailed in the respective compacts), Colorado water law, and local control. The Plan is the result of several years of statewide collaborative efforts and discussions about how the water needs of Colorado residents and downstream users will be met. “It sets forth the measurable objectives, goals, and actions by which Colorado will address its projected future water needs and measure its progress- all built on our shared values”. As a headwaters state we need to be actively involved in ensuring our water needs and rights are met, while also complying with interstate compacts.
The San Juan River, and its tributaries, contribute water needed to comply with local water rights user’s needs, as well as several interstate compacts (Colorado River Compact 1922, Rio Grande River Compact 1938, Upper Colorado River Compact 1948, others). Admittedly, how all these water rights needs are met is a very complex and confusing scenario, under which SJWCD is charged with accomplishing our mission under State statute. Nonetheless, the Water District is responsible for ensuring the conditional water rights owned by the District taxpayers are utilized to meet our shared water needs. In order for the District to better understand how the District’s taxpayers want that to happen, we need your input.
We hope to finalize our Strategic Plan that outlines our implementation of the statewide Plan in the next couple months.

It has been a rough year for operations at the Shoshone hydropower plant in Glenwood Canyon.
First, ice jammed the plant’s spillway in February, damaging equipment that required repair. The plant came back online in July but was able to generate electricity for only a few weeks before the Grizzly Peak Fire burned down its transmission lines.
According to the plant’s owner, Xcel Energy, the electricity impacts of the outages at the 15-megawatt generating station have been minimal, and the utility expects the plant to go back online this week. But while the electric grid can manage without the plant, the outage presents a much bigger threat to the flows on the Colorado River because the plant has senior water rights dating to 1902.
This means that any water users upstream with junior rights — which includes utilities such as Denver Water that divert water to the Front Range — have to leave enough water in the river to meet the plant’s water right of 1,250 cubic feet per second when the plant is running. When the Shoshone makes a call, the water makes its way through the plant’s turbines and goes downstream, filling what would otherwise often be a nearly dry section of river down toward Grand Junction.
A Shoshone call keeps the river flowing past the point where it would otherwise be diverted, supporting downstream water uses that would otherwise be impossible on this stretch of river. But when the plant is down, as it has been for most of 2020, that call is not guaranteed.
“Historically, what the Shoshone plant has done is kept a steady baseflow, which makes it easier for irrigators down here to be able to divert their own water right,” said Kirsten Kurath, a lawyer for the Grand Valley Water Users Association, which represents agricultural water users. “When the river goes up and down, it takes a lot of operational effort.”
The Shoshone water right also supports important nonconsumptive water uses. It provides critical flows needed for fish habitat and supports a robust whitewater-rafting industry in Glenwood Canyon. When the river drops too much below 1,250 cfs, it can create for a slow and bumpy ride.
“Customers get off and think, ‘Ugh, it would have been more fun to go to Disneyland,’ ” said David Costlow, the executive director of the Colorado River Outfitters Association. “Much lower and you are really scraping down that river and at some point you just pull the plug.”
The nearly year-long outages at Shoshone have many on the river worried. When the plant is down for repairs or maintenance, it does not make its call on the river allowing users upstream — including those that pipe water to the Front Range — to begin diverting. The Shoshone call can be the difference between the water remaining on the Western Slope or being diverted to the Front Range. Long outages, such as this one, reveal the vulnerability of the water on which so many rely.
“It’s a critically important component to the way that the Colorado main stem water regime has developed over more than a century now,” said Peter Fleming, the general counsel for the Colorado River Water Conservation District. “It’s sort of the linchpin or the bottom card.”
Water interests on the Western Slope have made some headway in recent years to maintain the status quo on the river even when Shoshone is down. Most of the major junior water-rights holders upstream of the plant — including Denver Water, Aurora and the Colorado Big Thompson Project — have signed on to the Shoshone Outage Protocol (SHOP). When the protocol goes into effect, as it has this year, these diverters have agreed to manage their diversions as if the Shoshone Plant — and the call — was online.
The agreement has been in operation for about a decade, helping to maintain flows during periods where the plant has undergone repairs or maintenance. The agreement was formalized in 2016 with a 40-year term. While the outage protocol has staved off major drops in the Colorado River flow over the years, the agreement is not as secure as water users that rely on Shoshone’s flows would prefer.
“SHOP is the best alternative that we have right now, but it doesn’t completely restore the flows,” said Kurath. “And one of the other problems right now is that it’s not permanent.”
For water users downstream of Shoshone, SHOP has three major issues. First, it is only guaranteed for 40 years, which for water planners is considered a short time frame. Second, the agreement does not include every upstream diverter, meaning that it doesn’t completely restore the flows to the levels where they would be if the Shoshone plant were on. Third, the agreement allows some of its signatories to ignore SHOP under certain water-shortage scenarios.
Despite the drought this year, the conditions never reached a point where SHOP’s signatories were able to opt out of the protocol, so the agreement went into effect when river levels dropped. But even though SHOP worked this year, the long outages at the Shoshone plant highlight the uncertainty of the plant’s future.
“We’ve always been nervous about it,” Fleming said. “It’s an aging facility, it doesn’t produce a ton of power, and we don’t know how long it’s going to be a priority to maintain and operate.”
The River District has been working to negotiate a more permanent solution for the Shoshone water rights for years. They have considered everything — from trying to buy the Shoshone plant outright to negotiating with diverters on the river to make something such as SHOP permanent.
The Shoshone outages have given these efforts renewed importance. In a recent board meeting of the River District, Fleming said that resuming talks with Denver Water that had stalled during the pandemic is a top priority.
While Fleming would not elaborate on the specifics of the ongoing negotiations, all options have the potential to impact many water users on the river — even those who aren’t at the negotiating table.
“We don’t approach this like we have water rights that we don’t have,” Costlow said. “But our business depends on water, and it depends on water levels that make water fun.”
This story ran in the Nov. 13 edition of The Aspen Times.
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.
Rebecca Milvich has many fond childhood memories of playing in the pond on her family’s Old Snowmass property, which they purchased in 1985.
Every summer, the pond off Little Elk Creek Avenue in Old Snowmass, became the neighborhood hangout as Milvich and her siblings and friends swam and paddled a canoe. Still today, the pond, which is filled by a ditch branching off Little Elk Creek, brings the family joy as they admire the ducks, fish and muskrats that live there.
“Those are the passions that are wrapped around it,” Milvich said. “It’s very personal. It’s something that has enhanced our quality of life a thousandfold. Our ability to have a water feature has changed our lives for the better, for sure.”
But on Sept. 22, the Milvich family received a cease-and-desist order from the Colorado Division of Water Resources that said they had to stop filling their pond because of a downstream call on the Colorado River, in which water users junior to the Grand Valley irrigators’ water rights had to be shut off.
It turned out the Milvich family did not have a legal water right for their pond, making them one of the most junior water users on the Colorado River system and one of the first to be curtailed.
“We were from Southern California and we missed having the beach,” Milvich said. “And my dad was excited to purchase an actual piece of property that had water on it, totally not knowing that we were in some ways for these last 35 years breaking some rules and regulations. We had absolutely no idea.”
The Milvich family’s pond is not the only one in the area lacking a water right. DWR officials say undecreed ponds throughout the region are depleting the Colorado River system in a time when a climate change-fueled drought makes it more important than ever to account for every last drop of water.
The Glenwood Springs-based Division 5 engineer’s office issued five cease-and-desist orders for ponds without water rights this season in the upper Roaring Fork Valley. And officials say there are many more ponds like these out there. Some of them are recently built for fire protection.
The main concern with these ponds is water loss to the Colorado River system through evaporation. The bigger the surface area, the more water that is lost.
“A lot of the depletions are pretty small, but it’s death by a thousand cuts,” Division 5 Engineer Alan Martellaro said. “When you have these all over the place, they add up at some point.”
According to Colorado water law, anyone is allowed to divert water from a stream simply by putting it to beneficial use as long as it does not harm senior water-rights holders. To protect their ability to keep using the water and save their place in line, most users make their water right official by getting a decree through water court. This enshrines the water right in Colorado’s system of prior appropriation in which the older the water right, the more powerful it is.
“It’s a good idea because it protects your standing,” Martellaro said. “It protects your priority. That’s the whole point of a water right.”
That means ponds without a decree are last in line and are the first to be shut off when there’s a downstream call from irrigators in the Grand Valley, which have much older water rights — one from 1912 and one from 1934. Known as the “Cameo Call,” these irrigators can control all junior water rights upstream of their diversion at the roller dam in DeBeque Canyon.
Most summers, Grand Valley irrigators “call” for their water when streamflows begin to drop. In general, the drier the year, the earlier the call comes on. This year, the Cameo Call first came July 30 and went off at the end of irrigation season Oct. 26.
As long as the call is on, junior upstream water rights must be shut off or “curtailed” so that the downstream irrigators can get the full amount of water to which they are legally entitled. It is up to the division engineer’s office to decide exactly how to administer the call and which junior water rights to curtail, but undecreed water use is generally the first to go.
“When the call is on, they are stealing somebody else’s water if they don’t have a water right,” said Bill Blakeslee, water commissioner for District 38, which encompasses the Roaring Fork River watershed.
Blakeslee said he doesn’t like to issue cease-and-desist orders, and his goal is to educate people about the Colorado River system.
“We don’t like to do our business this way, but this is one of the tools we use to help people understand we don’t have as much water as we used to and we all need to take steps to preserve as much as we can,” he said. “It makes a statement to the general public that we are in a drought situation, so let’s not do things that continue to contribute to further loss of water.”
Even though the ponds are causing water loss to the river system at all times, Blakeslee said he can apply the pressure of the law only when there is a call.
“I can’t enforce the rules until the call goes on the system,” he said.
The Milviches were supposed to have stopped diverting water out of priority within 10 days of receiving the order or else face enforcement actions such as having to pay the state’s costs and legal fees. But Martellaro said his office so far has not fined the owners of any of the five ponds and won’t as long as they are working toward a solution. And since the Grand Valley call is now off the river, the issue is less urgent — for the moment.
Colorado is entering a period of tighter accountability for some water users as Lake Powell’s levels continue to drop and the threat of a compact call looms larger in a warming West.
A compact call could occur if the upper-basin states (Colorado, Wyoming, Utah and New Mexico) can’t deliver the 7.5 million acre-feet of water per year to the lower-basin states (Arizona, California and Nevada), as required by the Colorado River Compact, a nearly century-old binding agreement. Upper-basin water managers desperately want to avoid this scenario.
“I guess you could say one of the elephants in the room is the interstate compact situation,” Blakeslee said.
So what are the Milviches’ options to remedy the situation? In order to be allowed to keep using water for the pond when a call is on, they must replace that water to the system. One possibility is getting a contract for an augmentation plan with a local water-conservancy district to release water from Ruedi Reservoir to make up for depletions from the pond. The Milviches have met with an engineer to assess their options.
Whatever they decide, securing a water right through water court can be a lengthy, expensive process.
“We are definitely terrified about that reality,” Milvich said.
Aspen Journalism is a local, nonprofit, investigative journalism organization covering water and rivers in collaboration with The Aspen Times and other Swift Communications newspapers. This story ran in the Nov. 2 edition of The Aspen Times.
In November 2018, Marble Town Manager Ron Leach received a letter that he said was a wake-up call.
The letter was a notice from the Colorado Division of Water Resources that the town’s water rights had been “out of priority” for four weeks the previous August and September because of a call placed by a senior water-rights holder downstream on the Crystal River.
During drought years — and 2018 was an extreme one, with the Crystal running at less than 5% of average after peaking in May, several weeks earlier than usual — junior water-rights holders may have to curtail their water usage until the senior call is satisfied.
“Drought and water supply have been on people’s minds for a long time around here, but we’ve never gotten a letter like that,” Leach said.
The letter urged the Marble Water Company — the private nonprofit entity that delivers water to the town’s approximately 150 residents and a handful of businesses — to create a plan of augmentation, which is an alternate source of water such as a storage pond. Without augmentation, the letter warned, a call could subject Marble to a cease-and-desist order on its municipal water wells.
Several other neighborhoods that get their water from the Crystal also narrowly dodged a bullet that August. The same call put more than 40 homes in Carbondale at risk of not having water, according to Town Manger Jay Harrington.
“Firefighting capability was an issue, too,” Harrington said. “That’s where we had to scramble.”
Carbondale officials were able to make an emergency arrangement with another senior water-rights holder on the Crystal to temporarily borrow water to supply the homes. And they quickly set in motion plans to avoid the situation in the future. In essence, the town is shifting the supply for some of its water needs from the heavily irrigated Crystal to the more reliable Roaring Fork, as the town has three wells that draw from the Roaring Fork aquifer, and has the option to develop more wells. The town also owns 500 acre-feet of water in Ruedi Reservoir it can use to offset its well depletions from the Roaring Fork aquifer.
Up in Marble, Leach doesn’t have multiple, redundant water supplies to serve his constituents. Noting that Marble’s water supply barely exceeds peak summer demand, an engineering firm’s preliminary recommendation was for an 11-acre-foot reservoir, which would require 3 to 4 acres of flat ground.
“The town of Marble doesn’t have cash to do anything like that,” said Leach, who added that space in the constrained mountain valley might also be a hurdle. “There’s no easy solution.”
Still, Leach is confident something will get figured out — a state-funded water study of the Crystal was recently approved, he said — but a very dry 2020 has underscored that the water issue is not going away anytime soon. During what’s now widely accepted as a two-decade-long drought in the Colorado River basin, temperatures have risen, summer rains can’t be relied on and streamflows have dropped, with earlier peak flows sometimes leaving little water in streams by late summer. The state’s letter to Marble noted that “it is reasonable to assume that this administration scenario could happen more frequently in the future.”
To those who deal with water day to day, there’s no question climate change is here and its impacts are being increasingly felt in the summer.
“It all starts with climate change — that’s the big picture,” said Leach. “What’s happening in Marble, this is the micro-example.”
Other Roaring Fork municipalities are also grappling with climate-caused water supply issues. The city of Aspen, which provides municipal water from free-flowing Maroon and Castle creeks and has seen Stage 2 water restrictions enacted two of the past three summers, is creating a 50-year water plan — driven in part by climate-change impacts — that may include expanded water storage. In Basalt, the 2018 Lake Christine Fire came close to cutting power supplies, which could have caused the failure of pump stations that deliver water to users. And after one of Glenwood Springs’ water sources was temporarily shut down during this summer’s Grizzly Creek Fire, debris, ash, mudslides and fire retardant pose lingering hazards.
“We need to continually work on our water systems as we continue to adapt to climate change,” said Harrington. “We are going to have to figure out how to slow it down, but in the meantime, we need to take climate change into our planning.”
“We need to continually work on our water systems as we continue to adapt to climate change,” said Harrington. “We are going to have to figure out how to slow it down, but in the meantime, we need to take climate change into our planning.”
The heat is on
Warming temperatures, linked to increased global greenhouse-gas emissions, are the catalyst that impacts other key conditions in the mountains, including lower snowpacks and streamflows; earlier snowmelt and runoff peaks; more precipitation in the form of rain than snow; more frost-free days; and lower soil moisture.
As average temperatures rise in all seasons, heat waves like the one that gripped Colorado during the summer of 2020 are becoming more common. According to the National Oceanic and Atmospheric Administration, average temperatures from May to October in Pitkin and Garfield counties have risen more than 2 degrees Fahrenheit since the 1950s. Some months are warming faster than others. In Pitkin County, June, July and September have warmed by nearly 3 degrees since 1950, while in Garfield County, June and September are 3.5 degrees warmer.
Noting that 12 of the hottest 14 years in western Colorado have occurred in the past 18 years, Colorado River Water Conservation District general manager Andy Mueller said at a recent conference that “the biggest change in temperatures has been occurring within our district and eastern Utah, which is a real problem when you look at the fact that we’re the area that produces the most-significant amount of water in the entire rivershed.”
Scientists are in broad agreement that as long as greenhouse-gas emissions continue to rise — or even level off — temperatures will follow suit.
Projections for the region range depending on emissions scenarios, but nearly all of them forecast at least another rise of average temperatures of 3 degrees Fahrenheit by mid-century and a rise of approximately another 10 degrees by the end of the 21st century. To put this into perspective, a warming Aspen could have the climate of Carbondale or Glenwood Springs, while Glenwood would look and feel like Grand Junction in a few decades.
The atmosphere taketh away
Local summer precipitation trends are less clear. Monsoon rains — or the lack thereof — drive great swings year to year in summer precipitation, which is usually dwarfed, in terms of volume, by winter precipitation in the form of snow. Historical data shows no clear trends. A report prepared for the town of Carbondale says that average precipitation in the 20th century and since 2000 are about the same.
Still, the summer of 2020 capped a decade of multiple dry summers. Colorado this year saw its third-driest April-July period, according to the National Weather Service, and the 2.5 inches of precipitation Aspen had from June through August was nearly 2 inches below normal. It was the fourth summer in a row with below-average precipitation and the driest in that stretch — even the summer of 2018 saw more rain.
Precipitation projections are also not very clear — although some experts suggest that precipitation could decrease in the summer and increase in the winter. But whether there’s a little more or a little less rain and snow in the future — and the latest models show a long-term decline in the Colorado River Basin — scientists say it doesn’t matter.
“There’s more uncertainty in how much precipitation is going to change and less uncertainty about how much temperature is going to change,” said hydrology expert Julie Vano, who is research director at Aspen Global Change Institute. “And the effect of just having warmer temperatures means more water is leaving the system.”
Jeff Lukas, a researcher on NOAA’s Western Water Assessment team, put it this way: “A warming atmosphere is a thirstier atmosphere.” In the Roaring Fork Valley, he said, only about a third of all precipitation makes it into streams and rivers; the other two-thirds is reclaimed by evapotranspiration, which is the combination of evaporation from surfaces and what plants absorb then release. Since evapotranspiration is driven in large part by temperature, as temperatures rise, the amount of water in rivers declines.
“The atmosphere giveth and the atmosphere taketh most of it away,” said Lukas. “Warming is the factor — across all seasons and all water-cycle processes — that draws moisture away from the land surface before becoming runoff.”
The flow is low
After more than a century of diversions, dams, storage projects and other stream manipulations, it’s complicated to calculate trends in natural streamflow, the term for the amount of water in a river. But streamflow, also called runoff, has perhaps the most direct effect on water availability. And trends are not looking good.
Declining streamflows are also found up the Colorado’s tributaries. Taking into account water that would’ve been in the stream if it weren’t for diversions and ditches, Lukas calculated that between 2000 and 2018, the Roaring Fork River at Glenwood Springs had 13% less water than the 20th-century average. Analyzing data on the Crystal River near Redstone, he calculated a 5% drop in annual mean streamflow since 2000, compared with the latter half of the 20th century, but a 10% decline during drier years.
In that same analysis of the Crystal, Lukas found that the date of peak streamflow had shifted one week earlier since 2000: from reliably arriving in June to sometimes coming in May. Multiple studies across the Colorado basin have similarly calculated a one- to four-week earlier runoff — which means that high-country snowpacks are melting earlier, so that the highest volume of snowmelt rushing down those streams is coming earlier in the spring.
But an above-average snowpack doesn’t mean an equivalent runoff, as this past year has shown. After a good winter followed by a warm, dry spring and summer, just 55% of the upper Colorado’s runoff made it into Lake Powell.
“The expectation that this amount of snow leads to this amount of runoff — we’re just not seeing as much as we did in the past,” said Vano, the hydrology expert.
Earlier peak runoff and lower flows mean less water (especially in drought years) in late summer and early fall, a critical time for irrigation, recreation and natural systems. From late July through October, the Crystal River upstream from Carbondale has been flowing below half of average, lower than the instream flow water right held by the state for that stretch of river — but since irrigation rights are senior to the conservation right, there’s often no recourse. For example, that is what happened in August on another tributary of the Roaring Fork, when the Colorado Water Conservation Board, which holds 1,700 instream-flow rights throughout the state, requested administration of its instream rights on Hunter Creek, acknowledging that it would likely be “a futile call.”
“A river is not a river without water in it,” said Heather Tattersall Lewin, science and policy director for the Roaring Fork Conservancy.
As with higher temperatures, declining streamflows and earlier runoff are certain into the future, but how much will depend on emissions. A 2006 report by the Aspen Global Change Institute calculated that by 2030, peak runoff for the Roaring Fork River at Woody Creek will occur in May rather than June. And by 2100, the lingering snowpack we see on the high peaks in June will no longer exist, which means less water in the stream all summer. Add in increased demand from growth and diversions, and future Roaring Fork River flows through Aspen could go below required instream-flow levels for nine months of the year.
Downstream in Glenwood Springs, the Roaring Fork’s late summer flows could decline by 30% to 50% by 2070, according to a 2018 analysis by Lukas.
“Changes to water will touch nearly everything,” he said. “All the risk is on the dry side.”
The underlying factor
Another important factor to consider is one we don’t really see: soil moisture.
One of the metrics used to calculate drought severity, soil moisture has been studied locally by the Aspen Global Change Institute since 2013. This short period of record may preclude discerning any trends about whether local soils are getting drier, but the data does show how moisture levels can have a domino effect season to season.
Elise Osenga, community science manager for the institute, likens the soil to a sponge. A dry sponge, like dry soil, absorbs more water than when it’s wet, while a wet sponge, like saturated soil, lets the excess run off. The water that the soil doesn’t absorb goes into streams.
“Climate change is more likely to dry soils in the spring,” said Osenga, who explained that peak snowmelt and peak soil saturation happen around the same time in the mountains. “When that happens, we’ll see soils dry earlier in the summer and become more dependent on summer rain — which is problematic when we don’t get those rains.”
Each of the past three years, soil moisture in Pitkin County has dipped well under the 2013-2017 average for most of the summer. The drought year of 2018 saw an early snowmelt and soil drying, but fall rains helped soils recover, auguring well for the next year. Most remember the record snows of late winter and spring of 2019, but the lack of rain that summer dried things up. And 2020 largely mirrored 2018, although 2020 saw slightly better soil moisture until late summer.
This year, things may have cooled off since August, but drought conditions have worsened, with all of Colorado, as of Oct. 22, in some form of drought and 78% of the state in extreme or exceptional drought. This doesn’t bode well for spring.
With soil moisture, said Osenga, “what happens in September and October is actually really interesting, because it plays a big role in determining whether we start the next spring already at risk of a drought versus in better shape.”
With multiple dry years over the past two decades, some scientists are wondering if we’re entering a period of megadrought, which hasn’t been seen in several hundred years.
“It might be a combination of natural variability plus climate change — a double whammy,” said Vano.
No single drought is evidence of climate change, Lukas said, but “what we’re seeing since 2000 is that climate change is stacking the deck. We’re more prone to the deep droughts, the ones that sneak out of left field like in 2020.”
And even with good planning, that’s sure to make water managers in Marble and Carbondale and throughout the Colorado River basin nervous.
“We do see changing conditions, whether attributable to increased demand/development by water users, drought or long-term climate change,” wrote Colorado water commissioner Jake DeWolfe in an email. “Any of them leads to the same problem: a shortage of water. We are involved in planning for the future likelihood that we will need to limit, if not curtail, uses in Colorado to meet the needs of downstream states.”
An abridged version of this story ran in The Aspen Times on Oct. 30.
In response to increasing tributary flows, the Bureau of Reclamation has scheduled a decrease in the release from Navajo Dam from 500 cubic feet per second (cfs) to 400 cfs on Monday, November 2nd, starting at 4:00 AM. Releases are made for the authorized purposes of the Navajo Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the San Juan River (Farmington to Lake Powell).
The San Juan River Basin Recovery Implementation Program recommends a target base flow of between 500 cfs and 1,000 cfs through the critical habitat area. The target base flow is calculated as the weekly average of gaged flows throughout the critical habitat area from Farmington to Lake Powell.
The lawsuit filed in 2016 claimed the city’s stormwater control efforts were underfunded and understaffed starting in 2009 and for years afterward. The suit also said the city’s failure to control stormwater degraded, eroded and widened Fountain Creek and its tributaries.
City officials stepped up stormwater control efforts in recent years after voters approved a stormwater fee in 2017.
But for years, poor stormwater control sent silt washing down Fountain Creek to the Arkansas River where it filled in the channels of both waterways and caused flooding in communities downstream, including Pueblo and La Junta, said Jay Winner, general manager of the Lower Arkansas Valley Water Conservancy District…
The proposed consent decree will also hold the city of Colorado Springs accountable to complete the stormwater projects needed to improve water quality, he said. The document outlines required audits, milestones the city must meet, and hefty fines if it fails to complete the required work.
The proposed consent decree is expected to be finalized soon. It must be submitted to U.S. District Court Judge John Kane by Friday, according to court records. The judge set a deadline for submission of the decree, after the parties were granted six requests for more time to reach an agreement…
U.S. Department of Justice spokeswoman Danielle Nichols said the proposed consent decree requires the city to spend $11 million on projects intended to mitigate the alleged violations of water quality standards in Fountain Creek and its tributaries. In addition to helping reduce the flow of silt, the work will help keep oil, grease, heavy metals, pesticides, fertilizers and bacteria out of the waterways, she said…
Fulfilling the requirements of the proposed consent decree could require $100 million in spending to improve stormwater control and associated projects, Nichols said. However, the city would have spent $55 million of the $100 million anyway on operating, personnel and other costs, said Travis Easton, Colorado Springs’ public works director.
The $45 million required to fulfill the consent decree is in addition to the $460 million the city is spending over 20 years to build 71 stormwater projects to meet its 2016 agreement with Pueblo County, he said.
The spending on the consent decree includes $2.1 million mostly in fines that the Colorado Springs City Council approved Tuesday. That money will come from the general fund, not stormwater fees, Mayor John Suthers said.
The federal government will receive $1 million in fines and the Lower Arkansas Valley Water Conservancy District will receive $1 million in state fine revenue to fund projects, according to the proposed consent decree. Pueblo County will receive $25,000 to cover lawsuit costs and the conservancy district will receive $100,000 for lawsuit costs, the document shows…
The fine revenue set aside for the conservancy district will help it fund projects across its five-county territory and help it secure additional grant money to meet the needs for water quality projects, Winner said. The district needs to put in projects, such as riparian zones and ditch lining, he said.
The district could put in $100 million in water quality projects and still have work to do, he said.
In response to increasing tributary flows, the Bureau of Reclamation has scheduled a decrease in the release from Navajo Dam from 600 cubic feet per second (cfs) to 500 cfs on Tuesday, October 27th, starting at 4:00 AM.

From email from the Colorado Water Conservation Board (Rob Viehl):
The Colorado Water Conservation Board (CWCB) has drafted proposed revisions to the Rules Concerning Colorado’s Instream Flow and Natural Lake Level Program (ISF Rules). The revisions to the ISF Rules will: (1) address the rulemaking requirements of HB20-1157; (2) update a reference to the CWCB’s website; and (3) update references to Colorado Parks and Wildlife. Staff held two informal stakeholder meetings on August 3 and August 18, 2020 to discuss the draft ISF Rules revisions. Staff also has drafted a Statement of Basis and Purpose for the revised ISF Rules.
On September 16, 2020, the CWCB authorized staff to initiate the formal rulemaking process. On October 14, CWCB staff filed a Notice of Public Rulemaking Hearing and proposed revisions to the ISF Rules the Colorado Secretary of State, which will be published in the Colorado Register on October 25, 2020. The rulemaking hearing will be held on January 26, 2021. Applications for party status should be submitted to the CWCB’s Hearing Officer, Amy Beatie, by email to email@example.com and will be accepted through November 13, 2020.

From Colorado Trout Unlimited via The Sky-Hi Daily News:
A project designed to improve the Fraser River in Granby began construction Thursday.
Construction is expected to be completed by the end of November and the bridge across the Fraser River at Kaibab Park will be closed during the work.
The Granby Diversion Dam, which helps divert the town’s water supply and agricultural irrigation water, is an 80 foot wide, 3.5 foot high boulder structure that spans the Fraser River. At low flows, the dam is a barrier that prevents fish movement critical for a healthy fishery and blocks the movement of small non-motorized crafts that currently portage around it, according to a release from Trout Unlimited.
The project is the result of a partnership between Granby, Trout Unlimited and Grand County. Funds were contributed by the US Fish and Wildlife Service, the Colorado Water Conservation Board, and the Open Lands, Rivers and Trails Fund, with the Northern Colorado Water Conservation Board contributing most of the materials for the project and Colorado Parks and Wildlife providing assistance.
The goal of the project is to provide fish passage for trout and native species and for non-motorized boating recreation without interfering with water diversion for municipal and irrigation purposes. The project will also provide resilience for future flood events, facilitate natural stream processes like sediment transport and no rise in the 100 year floodplain.
Here’s a deep-dive into the proposed Whitney Reservoir Project from David O. Williams that’s running in The Rocky Mountain Post. Click through and read the whole article. Here’s an excerpt:
With Wednesday’s move by the Trump administration to weaken one of the nation’s bedrock conservation laws – the National Environmental Policy Act (NEPA) – all eyes will increasingly be on local opposition and regulation when it comes to major infrastructure on federal lands.
That’s pretty much what Eagle County Commissioner Kathy Chandler-Henry told me when I asked about the proposed Whitney Reservoir project currently being scoped out by the U.S. Forest Service along Homestake Creek in southeastern Eagle County. The reservoir is being proposed by Colorado Springs and Aurora to pump Western Slope water to the Front Range.
All that’s currently being considered by the Forest Service is a test-drilling project to detect fatal flaws and see if one of four possible dam configurations is feasible, at which point an actual proposal for Whitney Reservoir would be submitted and considered by the feds, including a possible request to shrink the Holy Cross Wilderness by up to 500 acres to realign the road.
The Forest Service was flooded with more than 500 online comments opposing the drilling and the reservoir, demanding higher levels of environmental scrutiny for a special use permit for the drilling project that could be issued under what’s known as a “categorical exclusion.” Opponents are demanding an Environmental Assessment (EA) or Environmental Impact Statement (EIS)…
What didn’t make it into my Vail Daily story due to space constraints was the Eagle County angle. It’s important because way back in the 1990s, when I first moved to the Vail area, there was a huge battle going on over what was then called Homestake II – a reservoir proposed for the same area by the same cities, which still hold 20,000 acre-feet of water rights here.
Eagle County used its 1041 permitting powers, which give counties some degree of local control over infrastructure projects with regional or statewide impacts, to deny Homestake II – a move that wound up in court and went all the way to the Colorado Supreme Court before Eagle County ultimately won. Those 1041 regulatory powers were granted by a state law in the 1970s.
All of that led to the Eagle River Memorandum of Understanding (MOU) that outlines how all the various stakeholders in the Eagle River Basin would work together going forward to resolve their issues. But one important thing remains true: Eagle County, not a signatory to the MOU, still has 1041 permitting authority.
So Chandler-Henry, the water leader on the board, had some important things to say last spring. First, on any proposal that would require redrawing the boundaries of the Holy Cross Wilderness Area: “I can tell you that’s not anything that we would ever be supportive of is moving wilderness boundaries.” Then, on the importance of local permitting power:
Chandler-Henry points out that federal protections have been stripped away by the current administration, with fens and ephemeral streams recently being removed from the definition of Waters of the United States by the U.S. Environmental Protection Agency. Those changes, she said, are making it much easier for water providers to get their federal permits in place.
“Which means 1041 is all the more important for local considerations,” Chandler-Henry said, adding she believes her constituents oppose a dam. “I think that that is going to be a huge public sentiment, that we don’t want anything there.”
That being said, the county has to be somewhat diplomatic on both the test drilling and a possible future reservoir. Eagle County officials said they are working with the Forest Service on the test drilling proposal and may comment later…
“Eagle County cannot take a position regarding, and will not be commenting on, any future reservoir project because of its permitting authority powers,” county officials said in an email. “Eagle County must avoid prejudging a file based upon this authority.
“Eagle County plans to meet with the USDA USFS to discuss procedural questions regarding the proposed Whitney Creek Geotechnical Investigation project. Depending upon the outcome of that conversation, Eagle County may or may not choose to provide comment [to the Forest Service],” officials added.
Chandler-Henry, who talked to me well before the formal test drilling application and the recent Trump move to gut NEPA, said the county is keeping an open mind on 1041 permitting for whatever proposal eventually comes before the board. However, she reiterated that shrinking the Holy Cross boundary – something Congress would have to approve – is a non-starter.
“Sen. [Michael] Bennett’s office says that whenever they’re approached by Aurora Water about moving those boundaries in Holy Cross, they say, ‘You need to go see what Eagle County thinks.’” Chandler-Henry added. “To date they have not done that because I think they know what we think about that.”
An official with Bennet’s office confirmed they are aware of the wilderness adjustment plan but are not supportive of pulling back boundaries to make room for a proposed reservoir because there is not broad local backing. Bennet has been a strong advocate of wilderness expansion, not shrinkage…
Conservation groups see this as a key issue, linking the test drilling to an eventual dam proposal that could lead to less wilderness. The original Homestake II proposal would have been in the Holy Cross Wilderness Area…
Chandler-Henry said Eagle County is firm on the wilderness issue but staying openminded on 1041 so any proposal can be weighed fairly on its merits.
“One of the things that we’re doing, which is going to be really useful, is trying to tie our 1041 permitting in with the community water plan that [Eagle River Watershed Council] is working on … because a 1041 allows us to look at environmental impact, economic impact, infrastructure,” Chandler-Henry said, adding the utility has been modeling for future growth.
“Those are always our concerns with any sort of 1041 permit,” Chandler-Henry added. “What happens if water is dammed up in a reservoir? Then what happens to the Eagle River, to the environment, to the subdivisions that are relying on that water, to the recreation economy?”
Chandler-Henry said Aurora Water has been a part of that planning process…
The U.S. Forest Service has been inundated with more than 500 online comments in opposition to a geotechnical and drilling study by the cities of Aurora and Colorado Springs to determine the feasibility of a second reservoir in the Homestake Creek drainage six miles southwest of Red Cliff, including objections from nearby towns and a local state senator…
Operating together as Homestake Partners, Aurora and Colorado Springs own water rights dating back to the 1950s that, under the 1998 Eagle River Memorandum of Understanding (MOU), ensure them 20,000 more acre-feet of average annual water yield. They’ve been studying four potential dam sites in the Homestake Valley several miles below the cities’ existing Homestake Reservoir, which holds 43,600 acre-feet…
Western Slope signatories of the Eagle River MOU were tight-lipped on the geophysical study and drilling. Jim Pokrandt, director of community affairs for the Colorado River District, declined to comment on the investigatory test work, saying only, “Yes, we have signed the MOU. That said … we are not participating in the Whitney Creek effort.”
Diane Johnson,communications and public affairs manager for the Eagle River Water & Sanitation District, said: “The short answer is we – [ERWSD] and Upper Eagle Regional Water Authority — support [Homestake Partners’] right to pursue an application for their yield. We trust the permitting process to bring all impacts and benefits to light for the community to consider and weigh in total.” Neither organization submitted a comment to the Forest Service…
Two prominent local conservation groups – the Eagle Valley Land Trust and the Eagle River Watershed Council – both submitted comments to the Forest Service expressing serious reservations about both the drilling and the possibility of a dam…
The Eagle River MOU was drawn up after a lengthy court battle that ended in the 1990s when Eagle County rejected the cities’ Homestake II reservoir proposal using its 1041 powers under a state law passed in the 1970s that gives counties permit authority over certain outside infrastructure projects that could impact the local economy and environment.
Besides Homestake Partners (the two cities), the MOU was signed by the Colorado River District, Climax Molybdenum Company, and the Vail Consortium consisting of the Eagle River Water and Sanitation District, Upper Eagle Regional Water Authority and Vail Associates (now Vail Resorts).
The two private companies signed onto the MOU – Vail Resorts and Freeport-McMoRan (Climax) – declined to comment on either the drilling study or Whitney Reservoir.
Any proposed water storage project by any of the signatories has to meet the objectives of the MOU, which are, “Develop a joint use water project in Upper Eagle River basin that minimizes environmental impacts, is cost-effective, technically feasible, can be permitted by local, state and federal agencies, and provides sufficient yield to meet the water requirements of project participants as hereinafter defined.”
ERWSD’s Johnson said the water provider can’t comment on Whitney Reservoir because its environmental impacts have yet to be defined, but she did have overall praise for the MOU.
“To date, water users in the Eagle River basin have received great benefits from the MOU,” Johnson said. “It has been the basis to develop key elements of the local municipal and snowmaking water supplies that have been essential to the economic vitality of our community.”
The MOU provides 20,000 acre-feet for the cities, 10,000 acre-feet of firm water yield for the Vail Consortium (meaning if there’s a shortage, those needs are met first), and 3,000 acre-feet of water storage for Climax. About 2,000 acre-feet were already developed with Eagle Park Reservoir, but that leaves 28,000 acre-feet of yield and 3,000 of storage undeveloped.
Here’s a guest column from Stacy Chesney that’s running in The Sky-Hi Daily News:
When it comes to collaboratively managing water supplies on the West Slope, Denver Water understands that we must walk the talk.
When talking about our new era of doing business, Denver Water’s CEO/Manager Jim Lochhead regularly cites that “instead of platitudes, politics or parochialism, you need to sit down and work together.”
And that is exactly what has happened since the signatories of the Colorado River Cooperative Agreement sat down on Sept. 26, 2013, to put the new framework into action that ultimately benefits water supply, water quality, recreation and the environment on both sides of the Continental Divide.
From it came the Learning By Doing cooperative effort to maintain and enhance the aquatic environment in Grand County, which has already seen huge successes in the Fraser Flats River Habitat work, stream sampling programs and the removal of 2,500 tons of traction sand from Highway 40 before it could impact water quality and trout habitat downstream in the Fraser River.
We’re also aware that dry and hot summers, like we saw in 2018 and are experiencing again this year, bring added stress to the fisheries, environment and ultimately the entire communities of Grand and Summit counties.
When the rivers are low, talking the talk also becomes imperative.
Water efficiency is always top of mind for the Denver metro area, and during times like this, conservation dominates our communication channels. If you live on the West Slope, you may not see Denver Water’s communications about efficiency, but we are focusing on conservation measures and fostering appreciation for our source water where it matters: our customers.
We know that using less water means more water can be kept in the reservoirs, rivers and streams that fish live in and Coloradans enjoy. And ultimately, Denver Water’s customers are answering that call despite enduring what is turning out to be one of the hottest and driest years on record.
Overall, residents of the Denver metro area are using less water than they did in other summers when it was similarly hot and dry. We see them being cautious and judicious with their water use and adjusting based on the weather. In fact, Denver Water customers cut their water use in half in a matter of days when it snowed earlier in September.
This is nothing new though. After the 2002 drought, Denver Water’s conservation campaign led to our per-person reduction goal of 22% from pre-drought levels — one that we’ve continued to maintain since 2016. We’ve taken that momentum and are now working directly with our customers, sending water use reports along with rebates and tips to inefficient users on how to better use water wisely.
We also continue to evolve everything we do, from leading the way with new water reuse solutions, to upgrading our Water Shortage Plan – developed with feedback from our partners at Trout Unlimited, Grand County and other Learning By Doing stakeholders.
Denverites value where their water comes from. We live in this great state because of communities like Grand and Summit counties that provide resources precious to all of us. This benefit was made even more valuable because of the pandemic this year – a reality that we don’t take for granted and continually stress to the 1.5 million people we serve.
Stacy Chesney is Denver Water’s director of public affairs.
The Waldo Canyon Fire changed the way our community looks at natural disasters. A project designed in response to side effects of the blaze is now completed, and aims to be proactive, rather than reactive.
Near Garden of the Gods lies the Camp Creek Drainage Improvement Project. It’s a 17-acre floodwater detention and sediment collection facility…
After the Waldo Canyon Fire, the burned vegetation was not able to absorb moisture in the way it normally would. Consequently, the area saw flooding, with sediment rolling down the hillsides as well.
So, the Camp Creek Drainage Improvement Project was designed, with the help of federal, state, and local agencies. A Federal Emergency Management Agency (FEMA) grant for $8.9 million bankrolled the project, as well as $844,000 from the city.
Representatives from FEMA and the state visited the completed project on Monday. “If we could do more mitigation across the country, we’d be a much safer country, we’d be a much more resilient country,” said Peter Gaynor, the FEMA Administrator…
In addition, approximately 100 people no longer live in the floodplain. “We’re really not moving people out of the floodplain, we’re moving the floodplain right? And so, we’re changing the shape and the footprint of the floodplain,” said Klein.
The 169 acre-foot storage reservoir is estimated to hold around 360,000 gallons of water, according to the Stormwater Enterprise Manager for the City of Colorado Springs, Richard Mulledy.
Mulledy said the project has made around 100 residents who previously lived within the floodplain safer. He also said they now do not have to pay for floodplain insurance, which can be expensive.
Plus, it will create better evacuation routes during floods if necessary.
Releases from the Aspinall Unit will be decreased from 1350 cfs to 1250 cfs on Monday, September 28th. Releases are being lowered while the Crystal powerplant is offline for maintenance. Diversions into the Gunnison Tunnel have also dropped over the last part of September. The actual April-July runoff volume for Blue Mesa Reservoir came in at 57% of average.
Flows in the lower Gunnison River are currently above the baseflow target of 890 cfs. River flows are expected to stay at levels above the baseflow target after the release change has arrived at the Whitewater gage.
Pursuant to the Aspinall Unit Operations Record of Decision (ROD), the baseflow target in the lower Gunnison River, as measured at the Whitewater gage, is 890 cfs for September and 790 cfs for October.
Currently, Gunnison Tunnel diversions are 950 cfs and flows in the Gunnison River through the Black Canyon are around 450 cfs. After this release change Gunnison Tunnel diversions will be around 900 cfs and flows in the Gunnison River through the Black Canyon will be near 400 cfs. Current flow information is obtained from provisional data that may undergo revision subsequent to review.
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.
Three agencies will use water from the Albuquerque Bernalillo County Water Utility Authority to protect Rio Grande silvery minnow habitat this fall.
On Wednesday, the water authority approved a lease of up to 7,000 acre-feet, or about 2.9 billion gallons, of its San Juan-Chama water to the U.S. Bureau of Reclamation at a cost not to exceed $700,000.
The San Juan-Chama project uses a series of tunnels and reservoirs to route Colorado River water into the Rio Grande Basin. Several cities, counties, pueblos and irrigation districts rely on the project for drinking water and agriculture.
The Bureau of Reclamation will pay $350,000 for the water. The Middle Rio Grande Conservancy District contributed $250,000 to the lease and the New Mexico Interstate Stream Commission contributed $100,000…
In 2016, the U.S. Fish and Wildlife Service released a new biological opinion regarding water management and endangered and threatened species such as the Rio Grande silvery minnow, southwestern willow flycatcher and the yellow-billed cuckoo.

Water agencies now manage the river to improve fish densities, but are not required to maintain certain river flow targets.
This year’s drought and minimal runoff have left water agencies scrambling to supply water to farmers and fish.
The MRGCD used 10,000 acre-feet from the water authority in June. The irrigation district had “repaid” that water to ABCWUA in late 2019 as a payment for a water loan from the early 2000s. But the district was forced to ask for the water payment back after running out of storage water.
Another release of stored water from El Vado Reservoir in July helped extend the irrigation season by nearly three months…
Under the lease, the water can be released from Abiquiu Reservoir through the end of 2022. Revenue from the lease will help fund the water authority’s program to plan for future water supply and demand.
The water authority has a contract with the U.S. Secretary of the Interior for about 15 billion gallons of San Juan-Chama water each year – making it the largest user of the project.
With five of Greeley’s six high mountain reservoirs in the burn area, erosion is expected to carry sediment into Greeley’s water supply. Left untreated, that could affect the city’s water quality. But officials are already planning to make sure that doesn’t happen.
“When fires burn, if they’re hot enough, they can actually burn underbrush and soil,” said Adam Jokerst, Greeley’s deputy director of Water Resources, adding that vegetation is burned up as well. “With the lack of the vegetation … you can get increased erosion when it rains or when the snow melts.”
That erosion carries sediment into the Poudre River, which pulls water from the reservoirs to supply water for the city. Water with high sediment content can be harder to treat, Jokerst said, but it is possible to treat safely.
For better or for worse, Jokerst said, Greeley water officials have a lot of experience handling erosion into the water supply after dealing with the impacts of the High Park Fire in 2012. That fire burned more than 87,000 acres, making it the sixth-largest in state history.
There are at least a few steps to take to mitigate erosion impacts: aerial mulching, felling trees and adding flocculants during the treatment process. For aerial mulching, crews drop shredded wheat chips or straw from a helicopter. The mulch reduces erosion and helps with revegetation. Cutting down the burned trees and letting them fall into the gullies and rills — the channels created in the soil by water erosion — prevents stormwater and meltwater from carrying added erosion into the water supply.
Jokerst said it’s common to see the water get murkier during the runoff season every year. To provide clean, clear drinking water when that happens, crews use more flocculants, which are chemicals that help to separate the water from the sediment, in the treatment process. If there’s very high sediment content at the Bellvue Treatment Plant, officials can turn off the plant so it stop pulling water from the Poudre, Jokerst said. The city can then use the Boyd Treatment Plant…
If the fire keeps on into snowfall season in the winter, Jokerst said crews will have to wait until the spring to start on erosion control measures. Greeley officials are working with the city of Fort Collins, Northern Water and the Coalition for the Poudre River Watershed, a nonprofit Jokerst said will be a key entity in the post-fire recovery.
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.”
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.

As most of western Colorado is in an extreme drought, most of eastern Colorado is experiencing moderate to severe drought. While earlier in the summer southern Colorado was experiencing the driest conditions, the driest conditions now take up the western half of the state. The dryness extends into the Denver metro area and creeps to the east in the southernmost part of the state.
Treste Huse, a senior hydrologist for the National Weather Service in Boulder, explained that drought in Summit County started slowly this spring, then progressed to an extreme drought quickly. She explained that Summit County saw a dry fall and while winter saw a decent snowpack, the dry spring meant that the soil moisture was fairly dry going into the summer, which increased the wildfire danger. The U.S. Drought Monitor summary noted that topsoil moisture Sept. 13 was rated very short to short in Colorado.
Huse said that Summit County entered abnormally dry conditions by the end of May. The northern tip of the county went into a moderate drought toward the end of July. In mid-August, the area north of Dillon entered a severe drought. By Aug. 18, the whole county was in a severe drought with extreme drought in the north end of the county and the county was fully enveloped in extreme drought Aug. 25.
“It went fast, we just never got any rain,” Huse said. “That happens a lot of times with drought. You start to see a lot of impacts at once because they’re like, ‘I can go another month if we get some rain’ or ‘I can go two more weeks,’ but then finally there’s just no rain.”
In August, the Dillon weather station recorded 0.62 inches of precipitation, according to the National Weather Service almanac. The station records 1.93 inches in a normal year. So far in September there have been 0.41 inches of precipitation recorded at the station, while 1.02 inches is normal. However, September has seen 3 inches of snow so far, 2.5 inches above normal, which Huse said helped conditions.
Despite dry conditions, Huse noted that the reservoirs are still in good shape.
“What saved the reservoir storage was … the good snowpack of 2018-19,” Huse said.
Huse explained that the 2018-19 snowpack helped keep the reservoir full this year as this last winter, the snowpack barely reached average. Currently, Huse said that reservoir storage for the Colorado River Basin is 101% of average and at 86% capacity. As of Sept. 16, the Dillon reservoir is 95% full, according to Denver Water. Huse explained that parts of the Blue River are normal, such as the high reaches.
Last month was the hottest, driest August on record for western Colorado, according to Russ Schumacher, Colorado’s state climatologist and director of the Colorado Climate Center. He was one of three expert panelists who spoke at the third Yampa Basin Rendezvous discussion Thursday, which focused on changes in temperatures and precipitation amid what they described as a rapidly changing climate.
Routt County isn’t the only place topping charts. In its 2020 State of the Climate report, the National Oceanic and Atmospheric Association said the year is gearing up to be the planet’s second-warmest year in 141 years of temperature records. The warmest year thus far was 2016.
According to Schumacher, “These changes are going to affect the water cycle and everything that depends on it, which is pretty much everything.”
Among the most pressing threats climate change poses to Routt County are higher temperatures, reduced snowpack, increased risk of wildfires, more severe droughts and more extreme weather, according to a 2018 Greenhouse Gas Emissions Inventory. These would cause residual impacts to the local economy that depends on the ecosystem for everything from tourism to farming and to public health and safety, the report adds…
Unprecedented drought conditions pose serious risks to the Yampa Valley, from natural ecosystems to the people who depend on the health of those ecosystems. Ranchers have had an especially hard time this summer as they struggle to water their crops. For the second time ever, water managers placed a call on the main stretch of the Yampa River in August, meaning certain water users had to stop or curb their usage.
Longtime Steamboat Springs rancher Adonna Allen said her senior water rights meant she was not as affected by the call as some of her neighbors, but the dry summer has caused problems for everyone in agriculture.
Those growing hay have seen anywhere from 25% to 45% reductions in yields, Allen said. To make up for the loss, Allen had to convert pastures her family normally uses for grazing their cattle into hay fields, pastures she has not touched in 10 years…
Among the most devastating effects of hot, arid conditions for Colorado has been the propensity for large wildfires. The Pine Gulch Fire, sparked by lightning July 31 near Grand Junction, is the state’s largest wildfire in Colorado history. As of Friday, it was more than 139,000 acres in size and 95% contained, following about six weeks of firefighting efforts.
The Middle Fork Fire, 10 miles north of Steamboat, had grown to 5,445 acres Friday, according to the U.S. Forest Service. It continues to spread, fueled by gusting winds and dry weather.
Even after the flames are extinguished, such massive wildfires pose long-term hazards, such as flash flooding, mudslides and debris flow…
Snowpack across Colorado has been thinning since the 1950s, according to the Environmental Protection Agency, with losses as much as 60% at some measurement sites. Scientists from Colorado State University and the University of New Hampshire project further reductions in snowpack by the end of the century, with losses as high as 30% in some areas.
That said, the northern mountains, including the area of Steamboat Resort, are less vulnerable to decreases in snowpack than southern parts of Colorado, Schumacher said. This is because the weather patterns that can deliver large snowfall are more dependable than farther south, where he described winters as either “boom or bust.”
Here’s the release from the Bureau of Reclamation (Peter Soeth):
The Bureau of Reclamation is launching a prize competition to improve short-term streamflow forecasts. Evolving data science such as artificial intelligence, machine learning and high-performance computing are starting to be used in streamflow forecasting. The Streamflow Forecast Rodeo competition seeks to spur innovation using these technologies.
Reclamation is making up to $500,000 available through this prize competition.
“Streamflow forecasts are integral to managing water,” said Reclamation Commissioner Brenda Burman. “Finding improvements to forecasting will allow water managers to better operate their facilities for high flows, mitigate drought impacts and maximize hydropower generation.”
This competition delivers on the Department of the Interior and Reclamation’s commitment to improve water availability. It also supports the goals of the President’s memo on Promoting the Reliable Supply and Delivery of Water in the West.
The competition will begin with a “pre-season” in August, followed by a year of real-time forecasting beginning October 1, 2020. The pre-season will allow competitors to build and refine their forecast methods. The real-time forecasting competition will have solvers forecast streamflow for the next 10 days, updated daily at multiple locations across the West, for the duration of the competition.
Reclamation is partnering with the CEATI International’s Hydropower Operations and Planning Interest Group, NASA Tournament Lab and Topcoder on this crowdsourcing competition. Partnering with CEATI HOPIG includes a companion project that will provide benchmarks against which the competitors will be evaluated, as well as scoring of solver forecasts by RTI International. Other CEATI HOPIG members making contributions include Department of Energy’s Water Power Technologies Office, Tennessee Valley Authority, Hydro-Quebec, and Southern Company.

It has awarded more than $1,000,000 in prizes through 22 competitions in the past 6 years. Please visit Reclamation’s Water Prize Competition Center to learn more.
Now environmental and water quality experts are bracing for more substantial impacts on the Poudre River and the people who depend on it for drinking water, farming, industry and recreation. Degraded water quality, enhanced flood risk and threats to aquatic wildlife are all distinct possibilities as the blaze takes its toll on a delicate, far-branching river ecosystem that had largely recovered from the impacts of the High Park Fire.
The coming weeks and months will bring more news about what the Cameron Peak Fire will mean for the Poudre River. Until then, some staff of the agencies that monitor the river are in a similar position to the rest of us: Stuck in an anxious waiting game as the blaze continues, temperatures warm up and many details about the fire remain obscured in the ever-present haze.
“There are still so many uncertainties,” said Jen Kovecses, executive director of the Coalition for the Poudre River Watershed. “We’re certain about how big the fire is, but we’re not certain about its intensity on the landscape and what it will look like. That’s going to be the missing puzzle piece that we need to understand the full suite of post-fire impacts from this event.”
The aftermath of the High Park Fire offers a glimpse, albeit not an ironclad preview, of some impacts that could come from the Cameron Peak Fire. It all starts with the fire burning away the carpet of leaves, twigs, branches and other vegetation on the forest floor, known as “duff.”
“The fire can consume both the forest canopy and the material on the ground, which is a big problem, because now we have bare soil exposed,” said Pete Robichaud, a research engineer with USDA Forest Service’s Rocky Mountain Research Station. “That forest floor duff layer is like a big sponge. It absorbs the water when it rains, it allows the water to percolate slowly into the soil — it’s great. Well, now the fire removes that, and when the rain comes, there’s no sponge.”
The other problem is smoke, which can seep into the forest floor and cling to soil particles as it cools and condenses, making them hydrophobic — or water repellent.
The two forces combined can leave the soil vulnerable to even a mild afternoon thunderstorm. Water reverbs off the forest floor and travels downslope to the river, dragging soil, sediment and ash along for the ride.
That’s what happened after High Park, which infamously turned the Poudre black in summer 2012.
“Without the ability to soak up water and temper the intensity of rain events, the system overall became a much flashier system,” said Jill Oropeza, director of sciences for Fort Collins Utilities’ Water Quality Services Division. “You’d see water levels rise really quickly; you’d see material from the hillslopes move into the river channel really quickly, and then the quality would change really quickly as well. You just had tons and tons of ash and sediment that got mobilized into the stream channel and then eventually conveyed downstream.”
Many communities in the West are growing, and in some places that’s putting pressure on already scarce water supplies.
That’s the case in northern Colorado, where a proposed set of reservoirs promises to allow small suburbs to keep getting bigger. The project, called the Northern Integrated Supply Project (NISP), has stirred up a familiar debate over how the West grows, and whether water should be a limiting factor.
NISP — with its two new reservoirs, and network of pipelines across a broad sweep of Northern Colorado — is close to being fully permitted, which would pave the way to begin construction of the infrastructure project to satisfy the needs of 15 fast-growing Front Range municipalities and water providers. The project promises to give those communities water to build new homes and businesses — without buying it from farmers.
Glade Reservoir is the proposed body of water that would fill a bathtub-shaped valley north of Fort Collins that currently acts as a straight stretch of Highway 287…
Glade would be one of the Western U.S.’s biggest new reservoirs to come online in the past couple decades. With a more than $1 billion price tag, a project of this size and scale has those who live near the new reservoir and along pipeline routes concerned…
Northern Water, the quasi-governmental agency that moves water through tunnels, canals and reservoirs across a broad swath of Northern Colorado, is pushing for NISP’s construction on behalf of 15 other water providers, mostly small suburbs that have ambitions to grow. The communities of Dacono, Firestone, Eaton, Lafayette, Windsor and Severance are all participants in the project, among others…
NISP is getting close to the end of a federal, state and local permitting process. Since first formally submitting for permits in 2004, the project has jumped through regulatory hurdles like a federal environmental impact statement, a water quality certification from the Colorado Department of Public Health and Environment, and a 1041 permit from Larimer County. The 1041 permit gives local governments in Colorado some oversight authority on large infrastructure projects within their boundaries…
[The Larimer County] voted to recommend the 1041 permit to the board of county commissioners, which then approved on a 2-1 vote the permit for the project…
The town of Erie, a rapidly growing community in Boulder County about a half hour from Boulder and north Denver, would be the largest recipient of NISP water…
After more than 15 years of permitting, countless hours of negotiation over the project’s mitigation plans, and millions of dollars spent on studies, surveys and outreach, the agency pushing for NISP, Northern Water, says it has made significant changes to the planned project in order to help the already overtaxed Poudre River. Opponents say the project will only hurt, not help.
The Cache la Poudre River, where NISP would draw water for its largest reservoir, is often referred to as a “working river.” It provides drinking water for cities and irrigation water for farms. During the summer months it’s popular with kayakers, tubers and anglers. It’s also home to fish, birds and other wildlife…
The project still needs one more federal approval from the Army Corps of Engineers before it’s considered to be fully permitted, and ready to head into design and construction phases.

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.”

In response to a cooler forecast and increasing tributary flows, the Bureau of Reclamation has scheduled a decrease in the release from Navajo Dam from 850 cubic feet per second (cfs) to 800 cfs on Saturday, September 12th, starting at 4:00 AM. Releases are made for the authorized purposes of the Navajo Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the San Juan River (Farmington to Lake Powell).
The San Juan River Basin Recovery Implementation Program has recommended flows in the critical habitat reach as close to 500 cfs as possible for the summer of 2020. This is within their normal recommended range of 500 to 1,000 cfs. This target base flow is calculated as the weekly average of gaged flows throughout the critical habitat area from Farmington to Lake Powell.
This scheduled release change is subject to changes in river flows and weather conditions. If you have any questions, please contact Susan Behery (email@example.com or 970-385-6560), or visit Reclamation’s Navajo Dam website at https://www.usbr.gov/uc/water/crsp/cs/nvd.html
In a joint letter Tuesday, water officials from Arizona, California, Colorado, Nevada, New Mexico and Wyoming asked Interior Secretary David Bernhardt to “refrain from issuing a Final Environmental Impact Statement of Record of Decision regarding the Lake Powell Pipeline until such time as the Seven Basin States and the Department of the Interior are able to reach consensus regarding outstanding legal and operational concerns raised by the proposed Lake Powell Pipeline project.”
If the approval process for the Lake Powell Pipeline is not halted so concerns can be addressed, the letter states it may result in “multi-year litigation” that could also complicate future interstate cooperation concerning use of the Colorado River…
Despite a potential threat of litigation if their concerns are not resolved, Brock Belnap, an assistant general manager at the Washington County Water Conservancy District, said Thursday the water district hopes issues can be resolved without too much disturbance to the pipeline’s timetable.
“We appreciate that they express they want to resolve the issues they may have and we are pledging likewise to work with them to address the issue they may have in regard to the Law of the River in the Colorado River,” Belnap said…
An example of the issues some of the other states have is that Washington County is geographically located in the Lower Colorado River Basin, Belnap said, and the compacts state that water rights cannot be transferred from the one basin to the other. However, Utah is counted among the Upper Colorado River Basin States, and the compacts also say each state has a right to develop its allocated portion of the Colorado River within its boundaries, he said…
The government received more than 10,000 public comments on an environmental impact report for the proposed pipeline before Tuesday’s deadline, U.S. Bureau of Reclamation spokesman Marlon Duke said. The Interior Department, which oversees the bureau, is expected to issue a final report, which could bring the project a step closer to approval.
Although the proposal isolates Utah from the other states that rely on the river, it’s committed to bringing water it’s entitled to tap to those who need it, said Todd Adams, director of the Utah Division of Water Resources.
He said the project has been under review for about 20 years, and many other projects have gone through federal review while states worked through unresolved issues…
Zachary Frankel, executive director of the Utah Rivers Council, attended the meeting and asked if the committee planned to halt the project due to the concerns expressed by the other states in Tuesday’s letter.
Utah’s largest new water diversion in Colorado River Basin ignites a modern water war, results in veiled threat of litigation by other states.
In a stunning letter to the Secretary of Interior, a coalition of state water agencies, large water suppliers, and Governors’ representatives of Nevada, Arizona, California, Colorado, Wyoming and New Mexico are asking that Utah’s controversial Lake Powell Pipeline be placed on hold.
The shocking move demonstrates how out of touch the Utah Division of Water Resources and its lobbying partners have been in understanding the impacts of climate change on the Colorado River and of the Pipeline’s impact to the water supplies of seven states. The letter notes:
“As Governors’ representatives of the Colorado River Basin States of Arizona, California, Colorado, Nevada, New Mexico, and Wyoming, we write to respectfully request that your office refrain from issuing a Final Environmental Impact Statement (FEIS) or Record of Decision (ROD) regarding the Lake Powell Pipeline until such time as the seven Basin States and the Department of the Interior (Interior) are able to reach consensus regarding outstanding legal and operational concerns raised by the proposed Lake Powell Pipeline project.”
The strong letter of opposition was signed by representatives of the Colorado River Board of California, the Arizona Department of Water Resources, the Colorado Water Conservation Board, the New Mexico Office of the State Engineer, the Southern Nevada Water Authority, the Colorado River Commission of Nevada and the State of Wyoming.
They joined scores of groups and many hundreds of people across seven states submitting comments of opposition to the Lake Powell Pipeline to the Provo Office of the Bureau of Reclamation for the DEIS. The project drew criticism across the American West because the Colorado River has dropped dramatically with reservoir levels at 50% of capacity in an era of water cuts and climate change.
This is a historic first for 6 of the 7 Colorado River Basin States to reprimand another state on what they see as:
“Serious legal concerns relating to the 1922 and 1948 Compacts, including the accounting of the Lake Powell Pipeline diversion and other operational issues under the Law of the River.”
Utah ignited the water war with other Colorado River Basin states by pushing the Lake Powell Pipeline even without a demonstrable need for the water. Utah water officials justified the Pipeline with a high municipal water use of over 300 gallons per person per day, while other cities like Las Vegas, Denver, Los Angeles and Phoenix have water use between 120 and 150 gpcd, or less.
In a separate letter, the Southern Nevada Water Authority noted:
“What the Utah Board of Water Resources characterizes as extreme conservation efforts and impractical conservation, are actually commonly applied in an efficient and effective manner in many other communities.”
“This project is water hoarding at its finest. Utah wants to cash in on its ‘water entitlement’ under the Colorado River Compact so badly that it is willing to upset the fragile balance of a basin that supports 40 million people, recreational and agricultural economies, tribal lands and cultures, and irreplaceable landscapes and ecosystems.” — said Jen Pelz, the Wild Rivers Program Director at WildEarth Guardians
“Secretary Bernhardt should listen to the six Colorado River states that just asked him to delay any decision regarding the Utah’s unnecessary and harmful proposed Lake Powell Pipeline. All six states, especially Arizona, would be hurt by Utah’s attempted water grab from the drought- stricken Colorado River.” — said Douglas Wolf, Senior Attorney, Center for Biological Diversity
“It is not often where grassroots groups and government water buffaloes are aligned on bad water projects, but the Lake Powell Pipeline is such a boondoggle that opposition is now widespread. We hope St. George finally begins to follow the lead of communities like Las Vegas, Denver, Albuquerque, Phoenix and others that have implemented world-class conservation programs.” — said Kyle Roerink, Executive Director of the Great Basin Water Network
A coalition of groups also submitted extensive comments opposing the embattled Lake Powell Pipeline. The coalition has requested the Bureau of Reclamation explore other less expensive and environmentally destructive means for meeting the water needs of residents of Washington County in southwest Utah. This is also an Alternative identified as missing from the DEIS in the letter sent to the Secretary of the Interior by the 6 State Coalition. The 224 page letter can be found HERE.
The letter was submitted by Utah Rivers Council, Save the Colorado, WildEarth Guardians, Great Basin Water Network, Living Rivers, Glen Canyon Institute, Utah Audubon Council, SUWA, Conserve Southwest Utah, Citizen’s Water Advocacy Group of Arizona, Sunrise Movement of Las Vegas, Progressive Leadership Alliance of Nevada, San Diego Coast Keeper and Grand Staircase Escalante Partners. It details flaws in Reclamation’s environmental review including challenging the basis and need for the project itself, the lack of examining more cost-effective and less destructive alternatives, and its failure to analyze and mitigate the environmental harms that would arise if the project goes forward.
The Lake Powell Pipeline is one of the projects identified by the Trump Administration–in its June 4, 2020, Executive Order No. 13927–to be fast tracked through the environmental review process.
From email from the Colorado Water Conservation Board (Rob Viehl):
Proposed Acquisition of Contractual Interest in Ruedi Reservoir Water for ISF Use on the Fryingpan River and the 15-Mile Reach of the Colorado River
The Colorado Water Conservation Board will be considering an offer from the Colorado River Water Conservation District, acting through its Colorado River Water Projects Enterprise (“District”) of a short-term lease of 3,500 acre-feet of water that the District holds in Ruedi Reservoir for instream flow (“ISF”) use. The proposal is to use the released water to supplement winter flows in the Fryingpan River below Ruedi Reservoir from January 1, 2021 – March 31, 2021; and from April 1 – December 31, 2021, to help meet or reduce shortfalls to the U.S. Fish and Wildlife Service’s flow recommendations for the endangered fish critical habitat in the 15-Mile Reach of the Colorado River. The Board will consider this proposal at its September 16-17, 2020 virtual meeting. The agenda for this Board meeting can be found at:
Consideration of this proposal initiates the 120-day period for Board review pursuant to Rule 6b. of the Board’s Rules Concerning the Colorado Instream Flow and Natural Lake Level Program (“ISF Rules”), which became effective on March 2, 2009. No formal Board action will be taken at this time.
Information concerning the ISF Rules and water acquisitions can be found here.
The following information concerning the proposed lease of water is provided pursuant to ISF
Decree: 81CW0034 (Second Filling)
Appropriation Date: 1/22/1981
Adjudication Date: 12/31/1981
Decreed Amount: 101,280 acre-feet
Bureau of Reclamation Contract: 139D6C0101
Contract Use: Municipal use in Colorado River Basin; includes “use of water by . . . piscatorial users, including delivery of water to supplement streamflow. . . .”
Contract Amount: 4,683.5 acre-feet
Amount Offered for Consideration: Up to 3,500 acre-feet.
Proposed Reach of Stream:
Fryingpan River: From the confluence with Rocky Ford Creek, adjacent to the outlet of Ruedi Reservoir, downstream to its confluence with the Roaring Fork River, a distance of approximately 14.4 miles.
15-Mile Reach of the Colorado River: From the confluence with the headgate of the Grand Valley Irrigation Company (lat 39 06 06N long 108 20 48W) downstream to its confluence with the Gunnison River.
Purpose of the Acquisition and Proposed Season of Use:
The leased water would be used to supplement the existing 39 cfs ISF water right in the Fryingpan River to preserve the natural environment, and used at rates up to 70 cfs to meet the Roaring Fork Conservancy and Colorado Parks and Wildlife flow recommendations to improve the natural environment to a reasonable degree. The leased water would be used to also supplement the existing ISF water rights in the 15-Mile Reach to preserve the natural environment from July 1 – September 30, 2019, and to provide water at rates above the existing decreed ISF rates to help meet or reduce shortfalls to the U.S. Fish and Wildlife Service’s (“USFWS”) flow recommendations for the endangered fish critical habitat in that reach to improve the natural environment to a reasonable degree from April 1 –December 31, 2019.
Water stored in Ruedi Reservoir will be released to the Fryingpan River during the winter time period. The existing instream flow water right is decreed for 39 cfs from November 1 – April 30. The objective of the lease would be to maintain Fryingpan River flows at a rate of 70 cfs to prevent the formation of anchor ice at times when temperatures and low flows could otherwise combine to create anchor ice, which adversely impacts aquatic macroinvertebrates and trout fry.
The 15-Mile Reach of the Colorado River provides critical habitat for two species of endangered fish: the Colorado pikeminnow and the razorback sucker. This reach is sensitive to water depletions because of its location downstream of several large diversions. It provides spawning habitat for these endangered fish species as well as high-quality habitat for adult fish. Due to development on the Colorado River, this reach has experienced declining flows and significant dewatering during the late summer months, and at times, there are shortages in the springtime. As a result, the USFWS has issued flow recommendations for the 15-Mile Reach since 1989 to protect instream habitat for the endangered fish.

Bottled water company Nestlé is seeking permission to extend its operations in Colorado’s Chaffee County, a move that is generating significant community opposition.
Nestlé Waters North America first won permission to export spring water from Chaffee County in 2009, building a pipeline and trucking the water to Denver where it is packaged.
The company hopes to renew its original 10-year permit to tap Ruby Mountain Springs near Buena Vista, which expired last fall. The water is sold under the Arrowhead brand.
Chaffee County Commissioners are expected to take up the matter at an Oct. 20 hearing.
Nestlé Natural Resources Manager Larry Lawrence declined an interview request, but in an email said the company strives to maintain environmentally sensitive operations and that extending the permit would create no new stress on the springs.
Separately company officials have said repeatedly that preserving water resources is key to their ability to continue selling water. The beverage maker has 25 plants in the United States, including the one in Colorado.
In the meantime, local activists have collected more than 1,200 signatures on Change.org opposing the permit extension.
Unbottle and Protect Chaffee County Water, with 300-plus members, said the permit renewal poses an ongoing threat to local water supplies due to chronic drought and climate change. Activists also say that Nestlé donations of bottled water to local nonprofits increases the county’s recycling costs, and that Nestlé has not followed through on some of the commitments it made to the county, including taking steps to preserve important property along the Arkansas River near the springs.
“We believe we are an environmentally sensitive county,” said Francie Bomer, one of the activists leading the effort to cancel the permit.
“We don’t like plastic and we don’t believe the benefit to the county is equal to the value of the water Nestlé is taking out,” Bomer said.
The conflict comes as bottled water manufacturers across the U.S and Canada face mounting criticism over their use of groundwater. Five states, Maine, Michigan, Montana, Oregon, and Washington, are moving to ban or sharply limit the industry.
Earlier this year Nestlé opted to sell its Canadian operations, exiting a country in which local opposition had grown strong, according to published reports.
Under its Chaffee County permit, Nestlé is required to monitor water levels in the Ruby Mountain Springs and to replace any water it takes under a replacement plan overseen by the Salida-based Upper Arkansas Water Conservancy District.
Such plans are often required under state law, and are designed to ensure water users downstream of diversion sites with more senior water rights aren’t harmed by upstream diversions.
Manager of the Upper Arkansas Water District, Terry Scanga, said the replacement plan relies on water from Turquoise Lake in Leadville, which fully covers any water removed from Chaffee County by Nestlé. Scanga said the district has no plans to contest the permit renewal.
Nestlé is required to monitor water levels and habitat conditions as part of its agreement with the county. In its 2019 annual report, the company said it extracted 89 acre-feet of spring water, 5.6 percent of the 1,573 acre-feet of overall flow measured. An acre-foot is equal to nearly 326,000 gallons.
If its permit is renewed, the company estimates annual production would grow at 2 percent annually, but would still be well below the amount to which it is legally entitled.
In addition, ongoing monitoring by the company shows that the spring recovers quickly as water is extracted and that no harm to habitat has been noted since 2010.
“To date, spring water production has been well below the permit limitations and at no time over the last decade of monitoring has stress to the spring system resulted in conditions where pumping was required to be reduced, either to meet criteria under the permit or due to observations that indicated operations were negatively impacting upstream or downstream users or the ecological and biological systems,” the report states.
Bomer is skeptical of those reports because they have not been independently verified by outside experts.
Earlier this year, in advance of the permit renewal effort, the county hired experts to evaluate Nestlé monitoring data, according to Chaffee County Attorney Jennifer Davis.
Whether Chaffee County will become another bottled water hot spot in the international battle isn’t clear yet.
“We are a tiny county. Are we part of that bigger effort? No. We’re just trying to protect our resources so they will be here when we need them,” Bomer said. “But if we contribute to to that effort, that would be okay.”

The second-ever call on the Yampa River was lifted [August 3, 2020] morning after a trio of water providers announced the release of up to 1,500 acre-feet of water from Elkhead Reservoir to support irrigators in the Yampa River Valley and endangered fish.
The latest call was placed on the Yampa River on Aug. 25. The first call was in the late summer of 2018, also after an uncommonly hot, dry summer. The release of the water has ended the immediate need for water administration, allowing irrigators who had been legally prevented from taking water to resume diversions.
Tri-State Generation and Transmission Association has begun releasing 500 acre-feet of its water, and the Colorado River District is releasing another 750 acre-feet of water that it controls from the reservoir near Hayden.
A third organization, the nonprofit Colorado Water Trust, will use money from the Colorado Water Conservation Board to support the upper Colorado Endangered Fish Recovery Program’s contract for additional water in Elkhead in 2020. The Colorado Water Trust also has raised private funds to support a potential release of 250 acre-feet of water to provide in-channel flows for endangered fish species in the Yampa.
Water will continue to be released from Elkhead Reservoir, as necessary, through September. Rain, snow and cloud cover could suppress demand.
Irrigators, fish feeling the heat
A statement from the River District and Tri-State emphasized the intention of helping irrigators.
“Agriculture producers in the western U.S. currently are being hit with the triple threat of drought, low prices and pandemic restrictions, so anything we can do to ease the burden of farmers and ranchers in the Yampa Valley is something we are willing and honored to do,” said Duane Highley, CEO at Tri-State, the operator of coal-fired power plants near Craig.
Andy Mueller, the general manager of the River District, echoed that theme.
“We hope these actions help alleviate the depth and severity of ranchers being curtailed and allow some of them to turn their pumps back on to grow more forage before winter,” he said.
“It was a crazy hot and dry summer,” said Andy Schultheiss, the executive director of the Colorado Water Trust. “There was just nothing left in the river — or, at least, very, very little.”
Schultheiss said the trust was interested in preserving habitat for fish and other species in the river, including fish in the lower reaches of the Yampa that are on the endangered species list. In August, the organization also contracted to release 500 acre-feet of water from the Stagecoach Reservoir, near Oak Creek, to ensure flows through Steamboat Springs.
Impact of the releases was reflected Thursday afternoon at stream gauges maintained by the U.S. Geological Survey. The river above the confluence of Elkhead Creek was running 102 cubic feet per second. Bolstered by the reservoir releases, however, it was running 125 cfs downstream at Maybell. It was 95 cfs at Deer Lodge, located 115 river miles downstream from Elkhead Reservoir at the entrance to Dinosaur National Monument, below several agricultural diversions.
A warming climate of recent decades and the weather of the past year probably both played a role in 2020’s second-ever Yampa call.
“August likely will end in the top 10 hottest and driest on record in the Yampa basin,” state climatologist Russ Schumacher said during an Aug. 25 webinar. “You see warmer-than-average temperatures everywhere except a couple of pockets in North Park.”
Many areas were 4 to 6 degrees above average, and some pockets were even hotter. Fall and winter temperatures are more variable, which summer’s are much less so, said Schumacher. “Having 5 or 6 to 8 degrees above average in summer is quite remarkable,” he said.
The River District’s Mueller nodded to this broader context.
“As drought and low flows promise to persist, today’s cooperative actions could help us learn and plan for an uncertain water future,” he said.
Regulation is new reality
What sets the Yampa River apart from other rivers in Colorado is its storied tradition: a river without administration. The contrast may be most stark with the South Platte, which drains the heavily populated towns and cities and still abundant farms on the northern Front Range. There, it’s barely an exaggeration to say that every drop is measured, ensuring that diverters are taking only as much water as to which they have rights.
The Yampa has typically met the needs of all diverters, including those of irrigators, who are responsible for nearly all the water consumed in the Yampa River basin on an annual basis. Diverters were on an honor system to take no more than their allocated share of water.
Putting a call on a river requires the sorting out of water rights under Colorado’s first-in-time, first-in-right hierarchy. Those with mostly older — and, therefore, senior rights — have first dibs but only to the amount they are allocated.
The call placed on the river Aug. 25 was triggered by agriculture users lower on the river, at Lilly Park near Dinosaur National Monument. They were failing to get the river’s native flows to which they were entitled within their priority of 1963.
To honor the seniority of those water rights, Erin Light, the division engineer, initiated a call on the river to ensure that the more senior right would get delivery of the water.
Those affected were all water users upstream, even to the headwaters, with junior or more recent allocations. Junior water users are cut off to the amount necessary to satisfy the call, which could be partially or completely, as per the needs of the downstream user with the senior but unsatisfied allocation.
Light last year announced that all water diverters must install headgates and measuring devices, to allow withdrawals to be controlled and measured. Some have done so, others have been given extensions and some others have failed to comply, she said. Those without headgates and measuring devices — even if they have a more senior water right — risk being cut off entirely when a call occurs.
This push to measure diversions began at least a decade ago, after Light arrived in the Yampa Valley. One of those she persuaded was Jay Fetcher, who ranches along the Elk River, northwest of Steamboat Springs. He remembers some grumbling. The informal method had always worked. Now he’s glad he can prove he’s taking his allocated water — and no more.
“Once we changed, we realized that it was a real plus,” Fetcher said. “We knew what we were doing with our water, and we could justify (our diversions), not only to ourselves, but to Erin and the state.”
Jim Pokrandt, the director of community affairs for the River District, echoed that sentiment.
“It’s in everybody’s best interest,” Pokrandt said, “to foster a solution that recognizes the reality, that doesn’t put agriculture out of business, while we are on the pathway to better water administration.”

Here’s an in-depth report from (Bruce Finley) writing in The Denver Post. Click through and read the whole article. Here’s an excerpt:
A hundred miles from Colorado’s Front Range house-building boom, field scientist Delia Malone dug her fingers into spongy high-mountain wetlands at the edge of the Holy Cross Wilderness.
She found, about 15 inches underground, partially decayed roots, twigs and the cold moisture of a fen. These structures form over thousands of years and store water that seeps down from melting snow.
Malone has been digging about 20 holes a day, surveying fens for the U.S. Forest Service, to better understand nature’s water-storage systems — which sustain vegetation and stream flows that 40 million people across the Colorado River Basin rely on in the face of increasing aridity.
Aurora and Colorado Springs are planning to flood these wetland fens and replace natural storage with a man-made system: a $500 million dam and a reservoir that may require changing wilderness boundaries.
The cities each own rights to 10,000 acre-feet a year of the water that flows out of the wilderness and would pump what the reservoir traps, minus evaporation, through tunnels under mountains to other reservoirs and, finally, to pipes that deliver steady flows from urban faucets, toilets, showers and sprinkler systems…
Fens play a key role ensuring that streams and rivers still flow after winter snow melts. And as climate warming leads to earlier melting and depletes surface water in the Colorado River, natural wetlands increasingly are seen as essential to help life hang on. The benefits stood out this summer as the West endured record heat, wildfires and drought…
Yet Front Range developers’ desire for more water is intensifying. Across the mountains at construction sites on high dusty plains, roads and power lines have been installed, heavy dirt-movers beep and carpenters thwack atop roofs.
Local governments already have approved permits allowing house-building at a pace that in some areas is projected to nearly double water consumption.
Colorado Springs officials issued 3,982 permits for new single family homes last year, 18% higher than the average over the previous five years, according to data provided to The Denver Post. They estimated the current population around 476,000 will reach 723,000 “at build-out” around 2070. This requires 136,000 to 159,000 acre-feet of water a year, city projections show, up from 70,766 acre-feet in 2019.
Aurora officials estimated their population of 380,000 will reach 573,986 by 2050. They’ve approved entire new communities, such as the 620-acre Painted Prairie with more than 3,100 housing units in the “aerotropolis” that Denver leaders have promoted near Denver International Airport, and projected current water consumption of 49,811 acre-feet a year will increase to 85,000 acre-feet and even as much as 130,158 acre-feet in a high-growth, rapid-warming scenario…
To make a new dam and reservoir more palatable, the cities are exploring unprecedented “mitigation” of digging up and physically removing the underground fens, then hauling them and transplanting them elsewhere to restore damaged wetlands. An experiment on a ranch south of Leadville, officials said, is proving that this could help offset losses of Homestake Creek wetlands.
This would challenge a federal policy laid out in 1999 at Interior Department regional headquarters in Denver that classifies fens as “irreplaceable.” The policy says “onsite or in-kind replacement of peat wetlands is not thought possible” and that “concentrated efforts will be made to encourage relocation of proposed reservoirs… that might impact fens, when practicable.”
Covered by grasses and shrubs, water-laden fens blanket the Homestake Valley — wetlands filled with porous peat soils that receive minerals and nutrients in groundwater. Moving such wetlands, if attempted, would require massive hauling of soil blocks combined with the delicate precision of an organ transplant to retain ecological functioning…
Some environmental groups are preparing for legal combat should the cities seek required state, county and federal permits. Others haven’t weighed in. Conservation Colorado leaders declined to comment on this water push.
Transplanting fens as mitigation to try to restore wetlands elsewhere “for our convenience” is impossible, WildEarth Guardians attorney Jen Pelz said. “Fens and other sensitive high-elevation wetlands are quite beautiful and mysterious, more art than science, not something we can re-engineer.”
Dams and diversions proposed in recent years around the West “are just as destructive as those built a century ago, and building dams today is actually more irresponsible because we know that dams disconnect aquatic and riparian habitat, cause species extinction, disrupt ecosystem function, dry rivers and harm native cultures and communities,” she said.
“We need to start removing dams, not building more. This project is one of many where water managers are looking to cash in on their undeveloped rights or entitlements at the expense of people and the environment. … It’s time to draw a line in the sand.”
These wetlands, located on a 150-acre parcel in the Homestake Creek valley that Homestake Partners bought in 2018, would be inundated if Whitney Reservoir is constructed. The Forest Service received more than 500 comments, the majority in opposition to, test drilling associated with the project and the reservoir project itself.

Farmington residents are being asked to voluntarily cut back on their water usage by 10% amid ongoing drought conditions.
The Farmington City Council approved a resolution enacting a stage one water shortage advisory on a 3-0 vote. The meeting was broadcast on Zoom and a recording will be available online at http://fmtn.org/AgendaCenter.
Community Works Director David Sypher said the city has struggled to keep Lake Farmington full.
“We are taking keeping our lake 100% full a little more seriously than we have in the past,” he said, explaining that the city not only provides water to its residents but also delivers water to other water systems.
Lake Farmington was approximately 98% full on Sept. 3, but has been dropping at a rate of 0.15 to 0.3% daily and, as of the meeting on Sept. 8, Sypher said the lake was 97.15% full.
A storm brought precipitation to the region as the City Council discussed the water shortage advisory, but Sypher said current forecasts are calling for 30 to 50% of normal precipitation in the upcoming months and the most liberal projections are anticipating moderate drought.
FromThe Santa Fe New Mexican (Scott Wyland) via The Taos News:
A severe, prolonged drought is reducing the river’s flows to the lowest levels in decades, affecting cities’ drinking water supplies and compelling farmers to adjust how they water their fields.
[Glen] Duggins grows chile peppers, alfalfa and corn on his 400-acre farm in Lemitar, a tiny community north of Socorro. He already faces the prospect of restaurants buying fewer goods from him during the ongoing novel coronavirus pandemic, when their operations have been limited by the state’s public heath orders. Now he’s also seeing higher costs to produce his crops due to pumping.
But he is fortunate, he said, because many farmers in the Middle Río Grande Valley don’t have water pumps and must shut down when the river gets low…
A thin mountain snowpack, recent heat wave and light monsoon have depleted water levels from the Colorado River Basin to the Chama River to the Río Grande. It’s perhaps the most arid year in a two-decade dry period in New Mexico, making climate scientists and water managers wonder whether this is the start of an even drier time that will demand a new, long-term approach to urban planning and water use.
Locally, the prolonged drought can be seen in cottonwoods’ foliage turning yellow six weeks early along a parched stretch of the Santa Fe River and the likelihood of the Buckman Direct Diversion — which pulls Río Grande flows for city of Santa Fe and Santa Fe County water users — suspending operations for the first time in its 10-year history.
Everyone must prepare for how a warmer climate will diminish water supplies and put more stress on humans and the ecosystem, said Dave DuBois, a state climatologist at New Mexico State University.
“We need to address climate change and adapt to it,” DuBois said. “Not just in the here and now, but the next 20, 30 years.”
One of the traditional “tragedy narratives” of western water is the idea that thirsty cities are draining our rivers. But in two of the last three years, precisely the opposite has happened here in Albuquerque.
We’ve been limping along on a very bad year on the Rio Grande, with some of the lowest flows through Albuquerque that we’ve seen in a while. And the limping will continue. But with irrigation water in storage just about gone, an agreement is taking shape that will use an unused chunk of Albuquerque’s imported Colorado River water to keep the Rio Grande from drying through Albuquerque in coming months.
This is possible because Albuquerque’s water conservation success has left it with more water rights than it currently needs, including water we import through the San Juan-Chama project, a transbasin diversion that brings Colorado River water through tunnels beneath the Continental Divide. Some of that, now sitting in storage in reservoirs up on the Chama, will be released in coming weeks to maintain flows in the river here in town.
A similar deal in the very dry summer of 2018 also used some of Albuquerque’s unused Colorado River apportionment to keep the Rio Grande wet.
To be clear, this isn’t a charitable contribution on Albuquerque’s part. As I understand the deal, three government agencies with a shared interest in keeping the river wet – the Middle Rio Grande Conservancy District, the New Mexico Interstate Stream Commission, and the U.S. Bureau of Reclamation – are paying the Albuquerque Bernalillo County Water Utility Authority for the water…
But it’s intriguing to see the traditional narrative turned on its head – water available for the environment because a city has more than it needs.
The Northern Integrated Supply Project achieved another important milestone on Wednesday, with the Larimer County Board of County Commissioners approving the 1041 Land Use Permit application on a 2-1 vote.
The permit will allow the construction of Glade Reservoir, its recreation components and the pipelines to convey water from the reservoir to participants throughout Northern Colorado.
Central to the permit is the framework for the development of Glade Reservoir as a future recreation area to be managed by Larimer County. Glade Reservoir, just north of Ted’s Place on U.S. Highway 287, will join Horsetooth Reservoir, Carter Lake, Flatiron Reservoir, Pinewood Reservoir and the future Chimney Hollow Reservoir as a site for water recreation, fishing, hiking and more.
The participants of NISP have agreed to spend more than $16 million to develop the recreation site, and they have purchased the former KOA campground nearby to create camping opportunities.
Another part of the permit dictates the route and procedures for the placement of pipelines to deliver high-quality drinking water to communities in Northern Colorado. It reiterates the commitment of NISP to convey roughly one-third of its water deliveries via the Poudre River through downtown Fort Collins, increasing the overall number of days available for recreation at the new Fort Collins Whitewater Park.
NISP has now received its permit from Larimer County for land use and from the State of Colorado for Water Quality and for Fish and Wildlife Mitigation and Enhancement. This fall, NISP anticipates receiving a Record of Decision from the U.S. Army Corps of Engineers. Next year, NISP anticipates working with the City of Fort Collins to coordinate on a route for a pipeline to pick up the Glade Reservoir water that has been conveyed through Fort Collins via the Poudre River.
NISP is being built to address future water needs for 15 municipalities and water districts, including the Fort Collins-Loveland Water District, the Town of Windsor and others throughout the region. Northern Water is coordinating the effort through the NISP Water Activity Enterprise.
