Ruedi Reservoir is at about its lowest level of the year — and also of the past 19 years — according to numbers from the Bureau of Reclamation.
As of Wednesday, the reservoir on the Fryingpan River contained 54,914 acre-feet of water and was about 54% full. And according to U.S. Bureau of Reclamation data, outflow is currently slightly more than inflow, meaning levels may not have bottomed out yet.
The last time the level was this low was in the drought year of 2003 when Ruedi hit 46,117 acre-feet, according to Timothy Miller, a hydrologist with Reclamation, which operates the reservoir. Many reservoirs across the West are at their lowest levels of the year right before spring runoff starts, and water managers will start to see in the next month what this year will bring and whether it’s enough to fill depleted storage buckets.
Despite the current low levels, Miller said forecasts show Ruedi should be able to fill this year — but just barely. The most recent forecast from the Colorado Basin River Forecast Center shows that spring inflow for Ruedi will be about 96% of average.
“If we continue to get average precipitation, we should be able to fill by the skin of our teeth,” he said. “We won’t have any extra water. It’s going to be a tight fill.”
In 2021, Ruedi, which has a capacity of about 102,000 acre-feet, was only about 80% full after spring runoff.
Something that may influence if and how Ruedi fills this year is a phenomenon called the “April hole.” Agricultural irrigators downstream in the Grand Valley usually begin filling their ditches around April 1, and if irrigation ramps up faster than the snow melts in the high country, there may not be enough water to meet their demand.
Grand Valley irrigators, with large senior water rights dating to 1912, can command the entire Colorado River and its tributaries in western Colorado by placing a call. This means water users with junior water rights have to stop taking water so that the Grand Valley irrigators can get their entire amount of water to which they are entitled. When these irrigators put a call on the river, known as the “Cameo call,” it can control all junior water rights upstream of their diversion at the roller dam in DeBeque Canyon.
The Cameo call doesn’t come in April of every year, but it did in 2021 and lasted for 16 days — the longest April hole ever. Dry soils and hot temperatures in 2020 and 2021, fueled by climate change and drought, robbed the river of flows and created conditions never before seen by water managers.
“Last year was definitely the extreme,” said James Heath, Division 5 Engineer for the Colorado Division of Water Resources. “We never had a call in April last that long. The prior longest was in 2002, with five days of call.”
Instead of curbing their water use when the Cameo call is on, some water users simply release water from Ruedi that they have bought and store there as part of an augmentation plan. The problem, Heath said, is that many of these water replacement plans counted on a call lasting at most seven days.
“What we are finding is a lot of the plans were originally decreed for a worst-case call scenario of seven days in April,” he said. “Last year, they were diverting out of priority and injuring the downstream water rights.”
Heath said his office is still figuring out how to address these shortfalls and analyze different entities’ augmentation plans. He said Ruedi had to release about 1,300 acre-feet of water last year to satisfy the Cameo call in April.
A consequence of low levels in Ruedi is a reduced capacity to generate power at the hydroelectric plant, which is operated by the city of Aspen. Steve Hunter, utilities resource manager with the city, said the bottom line is this: the less water, the less power that is able to be produced. Hunter said if water levels fall below 7,700 feet elevation, utilities staff may decide to shut the unit off because the water pressure may not be generating much power. Ruedi was at 7,708.7 feet Wednesday. When Ruedi is full, the surface elevation is 7,766 feet above sea level.
When hydropower production decreases, Hunter said Aspen fills its all-renewable portfolio by buying more wind power.
“When hydro goes down, wind picks up the slack,” he said. “We are not in a terrible place right now. We are not Glen Canyon Dam.”
Hunter was referring to water levels in Lake Powell, which last week dipped to their lowest ever, hitting a target elevation of 3,525 feet, just 35 feet above the minimum level needed to generate hydropower at the dam.
“Hydropower across the board in the West is being affected by drought,” Hunter said. “This is crunch time, just watching what happens in the next month as we approach peak snow-water equivalent and see what the snowpack does.”

The Marshall Fire that destroyed more than 1,000 structures in Boulder County Dec. 30 has increased the urgency of completing wildfire mitigation projects in the Aspen area and Pitkin County.
The U.S. Forest Service is working with the governments of Aspen and Pitkin County as well as fire districts and homeowners associations to identify places that are the highest priorities for fuels reduction. The private lands on Red Mountain and public lands surrounding the high-end neighborhood are one of the highest priorities…
Richards said the Marshall Fire that swept through parts of Louisville and Superior show the importance of fire mitigation on private lands as well as national forests…
A working group loosely referred to as the Roaring Fork Fuels Collaborative is looking at numerous wildland fire mitigation projects, including one called Sunnyside, which would treat lands adjacent to Red Mountain subdivision. Between 1,000 and 1,500 acres would be targeted, according to Kevin Warner, Aspen-Sopris District Ranger. It would require mechanical treatment of tree and vegetation removal and prescribed burns in areas away from homes. The earliest that project could advance is probably spring 2024, Warner said.
Cooperation from the homeowners would be essential so that land within the subdivision would be treated as well. Aspen Fire Chief Rick Balentine said his department is working on demonstration projects to show homeowners that easing wildfire risk doesn’t mean ruining their property…
The Forest Service led a project in 2016 to treat lands near Red Mountain in the Hunter Creek Valley. Additional work on up to 1,500 acres in Hunter Creek could be undertaken as soon as this spring, according to Gary Tennenbaum, director of the Pitkin County Open Space and Trails program. He credited the Forest Service for leading the successful 2016 project and not causing alarm in Aspen. He also credited the agency for its willingness to propose working close to Red Mountain…
Warner said five wildland fire mitigation projects throughout the region are being planned. The Forest Service and its partners probably don’t have the resources to pursue them all this year, but priorities will be dictated by factors such as moisture levels this spring and the ability to get a permit from the state over air quality.
The contending projects include 2,000 acres in Collins Creek east of the settlement of Woody Creek, 2,000 acres in Braderich Creek west of Redstone, the 1,500 acres in Hunter Creek in Aspen’s backyard, a project in Cattle Creek north of Basalt Mountain in Eagle County and a project in the Seven Castles area in Fryingpan Valley…
Pitkin County has budgeted $300,000 over three years to assist the Forest Service. The highest priority for the county is “where the forest meets homes,” said county emergency manager Valerie MacDonald. The county has collaborated in recent years on several small projects that reduced fuels on federal lands in the Crystal River Valley that are adjacent to private properties, such as Swiss Village, she said.
A project north of Redstone treated 100 acres. “It gives the historic town of Redstone a fighting chance to evacuate safety,” MacDonald said.
Like other speakers at the meeting, she said getting cooperation from private landowners is the key to building resiliency. Pitkin County is 83% public lands, but much of its private property is in what’s known as the wildland-urban interface…
The local planning comes as the U.S. Forest Service released a major new initiative called “Confronting the Wildfire Crisis.” It will target “firesheds” in the Western U.S. — areas 250,000 acres and larger with a high likelihood that an ignition could expose homes, communities and infrastructure to wildfire.
The initiative will target 20 million acres on national forestlands as well as up to 30 million acres on other federal, state and private lands over the next 10 years. It will also come up with a maintenance plan beyond the next decade.
President Joe Biden’s infrastructure bill earmarked $3 billion for the effort beyond regular funding for wildfire mitigation. The strategy is drawing criticism from some environmental groups.
Bureau of Reclamation warns of potential impacts to Aspen hydro plant, water contract holders
Water levels at Ruedi Reservoir could fall so low this winter that the city of Aspen could have difficulty making hydro-electric power and those who own water in the reservoir could see shortages.
That’s according to projections by the Bureau of Reclamation, which operates the reservoir near the headwaters of the Fryingpan River. At the annual Ruedi operations meeting on Aug. 5, officials estimated the reservoir will fall to around 55,000 acre-feet this winter, what’s known as carry-over storage. According to Tim Miller, a hydrologist with the Bureau of Reclamation who manages operations at Ruedi, the lowest-ever carry-over storage for the reservoir was just over 47,000 acre-feet in 2002, one of the driest years on record. Last year’s carry-over was about 64,000 acre-feet.
At 55,000 acre-feet, the elevation of the water is about 7,709 feet. That’s about two feet lower than Aspen officials would like.
“We don’t like being below 7,711,” said Robert Covington, water resources/hydroelectric supervisor for the city.
That’s because the hydro plant needs a certain amount of water pressure to operate. The higher the water elevation, the more water pressure there is.
According to Covington, power providers Xcel Energy and Holy Cross Energy sometimes temporarily and quickly shut down the hydro-electric plant when there are problems with transmission lines or they need to do repairs.
“It’s very common for these types of plants to automatically shut down,” Covington said.
The problem is that restarting the plant requires a larger amount of water than the 40 cubic feet per second that is roughly the minimum amount required to operate the plant efficiently.
“It’s very difficult for us to get back online so we end up pushing more water through for a very short period of time,” he said.
If Aspen has to shut down the plant because flows are too low, the city could purchase more wind power to maintain its 100% renewable portfolio.
“When we go lower on hydro, we go with wind, which is generally the most cost-effective,” said Steve Hunter, utilities resource manager with the city.
Shortages to contract holders
Another consequence of low carry-over storage means that Ruedi will start out even lower next spring when the snow begins to melt and the reservoir begins to fill again. That means if there is below-average runoff again, some contract holders who own water in Ruedi could have to take shortages, something that has never happened before, Miller said.
There are 32 entities that have “contract water” in Ruedi, which the bureau releases at their request. This is water that has been sold by the bureau to recover the costs of building and operating the reservoir. The contract pool is separated into two rounds and contract holders will take a previously agreed upon shortage amount depending on which round they are in.
“If we get another similar type of runoff this year, there will be shortages most likely to the contract pool,” Miller said.
But there are still uncertainties in predicting how low the reservoir will go. The biggest of these is how much water will be released for the benefit of the endangered fish in the 15-mile reach of the Colorado River near Grand Junction.
There is a 10,412 acre-foot pool available for the fish, but in dry years entities that store water in Ruedi will sometimes coordinate to release more fish water in the late summer and fall. This would draw down the reservoir even further. It’s still not clear how much water will be released this fall for the four species of endangered fish.
“The release defines the carry-over,” Miller said.
Despite initial bureau forecasts in April that projected Ruedi could probably fill to its entire 102,373 acre-foot capacity, Ruedi ended up only about 80% full this year. July 11 was the peak fill date at 83,256 acre-feet and an elevation of 7,745 feet.
“It was probably a little over-optimistic,” Miller said of the April forecast. “But at the time our snowpack was average. It was a reasonable forecast given the conditions.”
As climate change worsens the drought in the Western U.S., Ruedi is not the only reservoir to face water levels so low that they threaten the ability to produce hydroelectric power. Last month, the bureau began emergency releases from Upper Basin reservoirs, including Blue Mesa on the Gunnison River, to prop up levels in Lake Powell and preserve the ability to produce hydropower at Glen Canyon Dam.
This story ran in the Aug. 10 edition of The Aspen Times.
High up on Colorado’s Independence Pass, a narrow, winding road weaves through the evergreens and across mountain streams, up and over the Continental Divide at more than 10,000 feet. At one point that road crosses a canal.
It’s easy to miss if you’re not looking for it, but that canal is part of water infrastructure that makes life on Colorado’s Front Range possible.
The state has a geographical mismatch between where water shows up and where much of the population has settled.
“Wherever you are in this state, you’re either at the source of the drinking water supply, you’re in the middle of the drinking water supply, or you’re at the end of the tap,” said Christina Medved, outreach director at Roaring Fork Conservancy. “So on the Western slope, we are at the source of the water.”
About 80% of Colorado’s water falls on the western side of the state. Much of it is high-mountain snow and rain that eventually trickles down into streams and rivers like the ones on Independence Pass.
But about 80% of Colorado’s people live on the east side of the mountains. Because of gravity, that water doesn’t flow to them naturally. Instead, Colorado’s heavily-populated Front Range relies on a massive plumbing system to keep drinking water flowing to its taps.
For a century and a half, engineers have carved up the mountains with tunnels and canals that pipe water across the state through trans-mountain diversions. Some of that infrastructure is nestled near the high-alpine headwaters of the Roaring Fork River, which eventually flows through Aspen and Glenwood Springs on its way to the Colorado River. Near Lost Man reservoir, a dam and tunnel create a juncture between water that will follow that natural path westward to the Colorado, and water that will be diverted eastward through the mountains and onto cities such as Colorado Springs.
A tunnel through the mountains draws in water that will pass through two reservoirs and the Arkansas River on its way to the southern portion of the Front Range. Water diverted from the Colorado River basin, through trans-mountain diversions, makes up 60 to 70% of the water used by Colorado Springs. Denver, Greeley, Fort Collins and smaller municipalities on the Front Range also rely heavily on Western Slope water.
And these kinds of set ups aren’t confined to Colorado. Similar systems bring water to big cities all across the region. Salt Lake City, Albuquerque and Los Angeles rely on canals and tunnels to ship faraway water into their pipes. New ones are in the works on the Front Range and in southern Utah.
But these systems aren’t without critics.
“When you first learn about it, the concept of a trans-mountain diversion is crazy,” said Andy Mueller, general manager of the Colorado River Water Conservation District. “It seems wrong. It seems antithetical to the health of the river. And I have to say all of that’s true.”
His organization was set up in the 1930s to oppose these diversions and ensure that there is enough water for people on the Western side of the state…
The issue is, contemporary environmental values aren’t written into the West’s water law. Instead, water use is defined by regulations written when Colorado first became a state in the 1800s. The rules say that if you have rights to use water, it doesn’t matter if you want to use it hundreds of miles away from its source – even if that requires miles of cross-mountain plumbing to do so.
At this moment, there is less water to pull from in every part of the state. The Front Range escaped from drought after steady spring rains, but those high-mountain areas that usually provide a dependable source of water for all of Colorado are experiencing a different fate. The western slope is deep in the second year of drought conditions, leaving snowpack and river flows lower than they should be.
Mueller thinks that only sharpens the need for the Front Range to curtail its water use. Although they retain the legal right to use a certain amount of water, he’s asking them to use less – which he says will promote the health of rivers and their ecosystems west of the divide.
On the Front Range, those on the receiving end of diversions say they are listening to their western counterparts when they put up distress signals during particularly critical times. They also say deliberate conservation work is paying off in the longer term. Nathan Elder, water supply manager for Denver Water, said over the past two decades, per capita water use in his district is down by 22%.
“Everyone in Colorado needs to decrease their use,” he said…
Amid tension between demands for water on both sides, exacerbated by extreme drought conditions, is the fact that there is not much of an alternative. Colorado’s water system is built to accommodate the fact that the majority of its people and the majority of its water are far from each other. Without fundamental changes to the bedrock of water law, those asking for water will have to work within a system built on trans-mountain diversions…
Some contingency planning – within the reality of a diversion-centric system – is already in place. In Colorado Springs, which receives some of the flow diverted from the top of Independence Pass, re-use practices are helping the city get more mileage out of the water it’s apportioned.
Abby Ortega, water resources manager for Colorado Springs Utilities, said reused water accounts for 26% of the city’s total portfolio and the city relies heavily on storage to get through dry years like this one.
But climate change threatens to increase the frequency and intensity of droughts, which has water managers on edge and looking more intently at ways to maximize what’s available.
“Every water planner in the state has some worry with the rapidly declining hydrology on the Colorado river,” Ortega said.
The Arkansas Valley Conduit promises to bring clean drinking water to more residents of southeast Colorado
n the 1940s, the Arkansas River was dammed south of town to build [John Martin Reservoir], a place locals call the Sapphire on the Plains. The reservoir was tied up in a 40-year battle until Colorado and Kansas came to an agreement, in 2019, to provide an additional water source to help keep the levels high enough for recreation and to support fish.
Forty years may seem like a long time to develop a plan to save fish and improve water levels for a reservoir, but southeastern Colorado is used to long fights when it comes to water…
For nearly a century, leaders in southeastern Colorado have worked on plans to bring clean drinking water to the area through the proposed Arkansas Valley Conduit, but progress on the pipeline project stalled after a major push in the 1960s. Pollution, water transfers and years of worsening drought amid a warming climate continue to build stress for water systems in the area. Adding to that, the area continues to see population decline combined with a struggling economy.
The water needed for the conduit will be sourced from melting snowpack in the Mosquito and Sawatch mountain ranges [ed. and Colorado River Basin]. Under the Fryingpan-Arkansas Project Act, passed in the early 1960s, the water has been allocated for usage in the Lower Arkansas Valley. The water will be stored at Pueblo Reservoir and travel through existing infrastructure to east Pueblo near the airport. From there, the conduit will tie into nearly 230 miles of pipeline to feed water to 40 communities in need.
Renewed plans to build a pipeline to deliver clean drinking water to the Lower Arkansas Valley are bringing hope for many people in southeastern Colorado. But in an area that is inextricably linked to its water, the future can seem unclear…
“Deliver on that promise”
“It was nearly 100 years ago, in the 1930s, that the residents of southeast Colorado recognized that the water quality in the lower valley of the Arkansas River was quite poor,” said Bill Long, president of the Southeastern Colorado Water Conservancy District and a former Bent County commissioner.
Water systems in the district, which includes Pueblo, Crowley, Bent, Prowers, Kiowa and Otero counties, have two main issues affecting drinking water.
The first is that a majority of those systems rely on alluvial groundwater, which can have a high level of dissolved solids. This can include selenium, sulfate, manganese and uranium, which are linked to human health concerns.
Second, the remaining systems in the water district rely on the Dakota-Cheyenne bedrock aquifer that can be affected by naturally occurring radionuclides. Radium and other radionuclides in the underlying geologic rock formation can dissolve into the water table and then be present in drinking water wells, also carrying health risks.
In 1962, residents in southeastern Colorado thought President John F. Kennedy was delivering a solution to their drinking water problem during a ceremony in Pueblo. Congress had passed the Fryingpan-Arkansas Project Act, and Kennedy came to Pueblo to authorize the construction of a pipeline to deliver clean drinking water…
Residents of the 1930s began working on ideas to deliver clean drinking water to southeastern Colorado. By the 1950s, they were selling gold frying pans to raise money to send backers to Washington, D.C., to encourage Congress to pass the Fryingpan-Arkansas Project Act. But it wasn’t until 1962 that the pipeline authorization became a reality.
Fast forward 58 years, and two more politicians came to Pueblo to address a crowd about the same pipeline project. This time, on Oct. 3, 2020, it was at the base of Pueblo Dam. Because of funding shortfalls, the Arkansas Valley Conduit was never built after it was authorized in 1962.
The Colorado communities could not afford to cover 100% of the costs, as initially required, so in 2009, the act was amended to include a 65% federal share and a 35% local cost share. Additionally, in 2020, Congress appropriated $28 million more toward the project, according to the water conservancy district.
That October day, Sens. Michael Bennet and Cory Gardner took turns talking about the importance of the project. They told a small crowd that when the pipeline is built, it will provide clean drinking water to 50,000 residents in southeastern Colorado…
The water conservancy district estimates the pipeline project’s cost will range from $546 million to $610 million…
Physical construction of the pipeline won’t start until 2022, according to the water district…
“The solution to pollution Is dilution”
A hand-painted sign with stenciled letters welcomes travelers on Highway 96 into Olney Springs. The highway cuts across four blocks that make up the width of the small town with around 340 residents.
Olney Springs is one of six water systems in Crowley County that plans to have a delivery point, known as a spur, on the Arkansas Valley Conduit. The plans for the pipeline call for two spurs in Pueblo County, three in both Bent and Prowers counties, and one in Kiowa County. Out of the 40 total participants, the remaining 25 are in Otero County…
Located along the Arkansas River about 70 miles east of Pueblo, La Junta is the largest municipality in Otero County. With its population around 7,000 and a Walmart Supercenter, a Holiday Inn Express and Sonic Drive-In, La Junta can feel like a metropolis when compared to Olney Springs.
La Junta is one of two Arkansas Valley Conduit participants, along with Las Animas, that uses reverse osmosis to remove potentially harmful and naturally occurring toxins from the water. Reverse osmosis is a process that uses pressure to push water through a membrane to remove contaminants. According to the Department of the Interior and the Bureau of Reclamation’s Arkansas Valley Conduit Environmental Impact Statement, reverse osmosis can treat source water to meet standards, but the brine from the process “is an environmental concern, and operation costs are high.”
The other participants use conventional methods to treat water. The environmental impact statement said those methods can be as simple as adding chlorine for disinfection and filtration or adding chemicals to remove suspended solids, but that those treatments “…cannot remove salt or radionuclides from water.”
Tom Seaba, director of water and wastewater for La Junta, said out of a total of 24 water districts in Otero County, 19 were in violation with the state due to elevated levels of radionuclide.
Four of the 19 came into compliance with the state’s drinking water standards after La Junta brought them onto its water system. The remaining 15 are still in violation with the state, according to Seaba.
La Junta spent $18.5 million to build a wastewater treatment plant that came online in 2019 to help meet water standards for its community. But the city’s water treatment came with its own issue: selenium.
After La Junta treats its water using reverse osmosis, the water system is left with a concentrate, which is safe drinking water. However, it’s also left with a waste stream high in selenium. “That wastewater has to go somewhere,” Seaba said. It goes to the city’s new wastewater treatment plant…
According to the environmental impact statement, “La Junta’s wastewater discharge makes up about 1.5% of average annual flow in the Arkansas River.” The study goes on to say that during drought or low-flow events, the wastewater discharge can contribute up to half of the streamflow downstream from the gage.
Seaba is looking to the Arkansas Valley Conduit as a possible answer. “The solution to pollution is dilution,” he said. The water from the pipeline will not have a selenium problem, Seaba explained. By blending water from the conduit with the selenium waste from reverse osmosis, La Junta hopes to reduce costs and stay compliant with Environmental Protection Agency standards to discharge into the river.
The environmental review studied a section of the Arkansas River from where Fountain Creek runs into the river east to the Kansas border. The study found that a section of the river was impaired by selenium…
“I sure don’t drink it”
The EPA sets a maximum contaminant level in drinking water at 5 picocuries per liter of air for combined radium and 30 micrograms per liter for combined uranium. If contaminant levels are above those numbers, the water system is in violation of drinking water regulations, which the state enforces.
According to data provided by the Colorado Department of Public Health and Environment, the Patterson Valley Water Company in Otero County, one of the 40 pipeline participants, had the highest result of 31 picocuries per liter for combined radium in 2020. In that same county, Rocky Ford, another pipeline participant, had a high result of 0.2 picocuries per liter for combined radium. According to the state health department, Rocky Ford’s combined radium sample numbers were last recorded in 2013.
Manzanola, also in Otero County and a pipeline participant, topped the list with the highest result of 42 micrograms per liter for combined uranium in 2020. In contrast, 19 other pipeline participants, from across the valley, had results of 0 micrograms per liter for combined uranium, according to the most recent numbers from the state health department.
Levels of the two carcinogens are sporadic throughout the valley. The average of the highest results of all 40 participants in the pipeline for combined radium is roughly 8 picocuries per liter and combined uranium is roughly 5 micrograms per liter. According to Seaba, averaging the members’ highest results might seem unfair to some individual water systems because it brings their numbers up, but what those averages do show is that water in Pueblo Reservoir, which will feed the future conduit, is approximately three times less affected by combined radium and combined uranium than the average of current water used by pipeline participants. In 2020, the highest result of combined radium in the Pueblo Reservoir was 2.52 picocuries per liter, and the highest result of combined uranium was 1.7 micrograms per liter…
“I sure don’t drink it,” said Manny Rodriquez. “I don’t think anybody in town drinks the water.”
Rodriquez, who grew up in and still lives in Rocky Ford, was not sure if the water at his apartment was in violation of the state’s clean drinking water act or not. State data showed at that time his water was not in violation. Colorado is required to notify residents if their water system is in violation of the clean drinking water act…
MaryAnn Nason, a spokesperson for the Colorado Department of Public Health and Environment, used an example to show how violations can add up: “If a public water system has two entry points that fail for both combined radium and gross alpha (measures of radionuclides), and they have those same violations for 10 years each quarter, that is going to appear as 160 violations on the website. But really, it is one naturally occurring situation that exists for a relatively long time,” Nason said.
For some residents like Ruby Lucero, 83, it makes little difference to her if her water is in violation with the state or not. She plans to buy her drinking water no matter what the results say about her tap water…
“The struggling farmer”
In the past decade, Otero County has seen a 2.9% drop in population. Residents have a ballpark difference of $38,000 in the median household income compared to the rest of the state, and the county is not alone. All six counties that are part of current plans for the Arkansas Valley Conduit are seeing economic hard times.
Adding to those factors is drought. Years of drought keep hitting the area’s No. 1 industry: agriculture.
The Rocky Ford Ditch’s water rights date back to 1874, making them some of the most senior water rights in the Arkansas River system. In the early 1980s, Aurora was able to buy a majority of those water rights. Over time, Aurora acquired more shares and has converted them to municipal use…
“We still have a heavy lift before us”
Planned off the main trunk of the Arkansas Valley Conduit, a pump station near Wiley will push water along a spur to support Eads in Kiowa County. Water that ends up in Eads will have traveled the longest distance of the pipeline project. The majority of the pipeline will be gravity-fed, but this section will need to be pumped uphill.
The journey is a good representation of Eads’ battle with water. Not only is clean drinking water needed, but the area is also desperate for relief from years of drought exacerbated by climate change…
Long said that Eads is different from a majority of the other participants in the project because it is not located along the Arkansas River…
The domestic water that will be delivered via the conduit is even more important for a town like Eads, said Long. “It’s very difficult to attract new industry when you have a limited supply of very poor water.”
Long believes the conduit will make a huge difference to support communities in the Lower Arkansas River Valley…
Long has been working on the Arkansas Valley Conduit project for nearly 18 years.
“After such a long fight, to finally be where we are feels good, but honestly I can say it doesn’t feel as good as I thought it would. Only because I know we have so much work still to do, and I know how difficult the past 18 years have been,” Long said. “We still have a heavy lift before us.”
Reservoir expected to reach only about 90% of capacity this summer
The dry, warm month of April prevented the snowpack from building and sunk the chances to fill Ruedi Reservoir this summer, according to the U.S. Bureau of Reclamation…
The snowpack in the upper Fryingpan Valley was only about 60% of median as of May 1, he said. Forecasts are for runoff into the reservoir to be only about 55% of average…
Ruedi Reservoir is at about 60% full right now. It holds 102,000 acre-feet of water. It would need about 42,000 acre-feet to fill.
Current projections are for it to reach about 90,000 acre-feet this summer, according to Miller…
The Roaring Fork River basin, like much of Colorado and the Western United States, has been battling a prolonged drought. AccuWeather Inc. reported Wednesday that 75% of the Western U.S. is experiencing drought conditions. About 21% of the areas are facing exceptional drought, which is the most extreme…
A lower water level in the reservoir also will mean lower releases into the lower Fryingpan River through the summer. Water levels won’t be as high as usual in late spring and early summer, so there won’t be a disruption to the Gold Medal trout stream.
However, low water levels and high summer temperatures are a regular cause for concern. The Basalt-based Roaring Fork Conservancy has sounded the alarm in past summers about high water temperatures stressing trout.
Water releases could increase in June once downstream entities that possess senior water rights make a “call” for water for agricultural uses, Miller said.
April Long, director of the Ruedi Water and Power Authority, said the reservoir is used to meeting numerous water needs in the Roaring Fork Valley and on the Colorado River system. It is hard to know the full impact of the reservoir not filling, she said.
Here’s the release from the Southeastern Colorado Water Conservancy District (Chris Woodka):
Five Directors were reappointed to the Board of Directors of the Southeastern Colorado Water Conservancy District, and were sworn in on Thursday, April 15, 2021.
Reappointed are: Seth Clayton, Executive Director of Pueblo Water, representing Pueblo County, and Secretary of the Board; Andrew Colosimo, Government Affairs Manager for Colorado Springs Utilities, representing El Paso County; Greg Felt, Chaffee County Commissioner and a member of the Colorado Water Conservation Board; Carl McClure, a Crowley County farmer; and Howard “Bub” Miller, an Otero County farmer and rancher.
The Southeastern District is the state agency responsible for the Fryingpan-Arkansas Project, which is operated by the Bureau of Reclamation. The Fry-Ark Project includes Pueblo Reservoir, Twin Lakes, Turquoise Reservoir, Mount Elbert Forebay and Power Plant at Twin Lakes, Ruedi Reservoir, a West Slope Collection System, and the Boustead Tunnel.
The Fry-Ark Project is designed to import 69,200 acre-feet annually for use by cities and farms in the Arkansas River basin from the Fryingpan River watershed near Basalt. Fry-Ark Operating Principles list environmental conditions that must be met when water is diverted.
The District also operates the James W. Broderick Hydropower Plant at Pueblo Dam, which was completed in 2019 under a Lease of Power Privilege with Reclamation.
The District is working with Reclamation to build the Arkansas Valley Conduit, a pipeline that will deliver a clean source of drinking water to 50,000 people in 40 communities east of Pueblo.
The District includes parts of nine counties, and has 15 directors who are appointed to 4-year terms by a panel of District Court judges.
Other directors of the Board are: President Bill Long, Bent County; Vice-President Curtis Mitchell, El Paso County; Treasurer Ann Nichols, El Paso County; Pat Edelmann and Mark Pifher, El Paso County; Patrick Garcia and Alan Hamel, Pueblo County; Tom Goodwin, Fremont County; Kevin Karney, at-large; and Dallas May, Prowers and Kiowa Counties.
Pitkin County on Wednesday inched a bit closer to having an additional 100 acre-feet of water flow down the Roaring Fork River with the approval of an intergovernmental agreement and memorandum of understanding.
Pitkin County commissioners unanimously approved on first reading the IGA with the city of Aurora and the MOU between the county, Aurora and the Bureau of Reclamation. The agreements are the final step in a yearslong effort by the county to get more water into the often water-short upper Roaring Fork by means of a complicated exchange.
As part of a 2018 settlement of a water court case, Aurora is allowed, in exchange for leaving more water in the Roaring Fork, to continue diverting water out of the headwaters of the Fryingpan River basin to the Front Range through the Busk-Ivanhoe system.
This can be done because Aurora owns about 5% of the diversions of the Twin Lakes Reservoir and Canal Company, the entity that owns and operates the Independence Pass Transmountain Diversion System.
The IGA and MOU bring the total amount of water to be left by Aurora in the Roaring Fork to 1,000 acre-feet. That amount is about half of the water that Aurora owns in the Twin Lakes company.
Pitkin County’s goal was to get more water into the habitually stressed reach of the Roaring Fork that flows through Aspen during the summer and fall. Aurora has released water into the Roaring Fork for the past two summers under this settlement agreement.
“It was definitely noticeable by users of the river, and they were excited,” said Commissioner Patti Clapper. “It worked exactly like we wanted it to work, and the fact that we were able to draw this water when we needed it most was really a key point in this whole deal.”
But the extra water in the Roaring Fork could be diverted and used by any downstream senior water-rights holder. The new agreements would allow Aurora — which still maintains ownership of the water, even though it’s being released to the benefit of Pitkin County — to “call” the water down to the confluence of the Roaring Fork with the Fryingpan in Basalt. This water could then be used to satisfy downstream water users, who usually meet demands by releasing water they store in Ruedi Reservoir.
Leaving this water, up to 900 acre-feet, stored in Ruedi would allow Aurora to take half that amount (up to 450 acre-feet) from Ivanhoe Reservoir and send it to the Front Range for municipal use. Pitkin County would be entitled to about a quarter of the water (up to 100 acre-feet), which Aurora would release back into the Roaring Fork, bringing the complicated exchange full circle.
Benefits to using Fork water
There are secondary benefits to using Aurora’s water released into the Roaring Fork to satisfy downstream needs and leaving stored water in Ruedi, said Pitkin County Attorney John Ely. Fewer releases from Ruedi means reservoir levels can stabilize, and it would be better for anglers in the Fryingpan’s gold-medal trout fishery.
“You won’t see as many surges of water being released from Ruedi down the lower Fryingpan, making it more difficult for fishermen to access the river,” Ely said. “Those three benefits alone are pretty good scores for us.”
Ely said with the additional 100 acre-feet on top of the earlier agreement already in effect, there could be an extra 20 to 30 cubic feet per second of water flowing down the Roaring Fork, making it possible to run the Slaughterhouse rapid later in the season, among other benefits.
“I think if we are going to get 20 cfs on top of that, that saves the life of the upper Roaring Fork,” said Commissioner Greg Poschman. “I am really, really grateful and excited to see this happen.”
The IGA will have a second reading and final approval by commissioners on April 28. The agreement will allow the governments to move ahead with a storage contract and water-court filing to execute the exchange.

Water forecasting agencies in Colorado have released their April streamflow predictions, confirming what many already knew: Drought and dry soils will diminish rivers this spring.
“The main story of this water supply outlook season is the effect of last year’s drought going into winter,” said Karl Wetlaufer, a hydrologist and assistant supervisor with the Natural Resources Conservation Service Colorado Snow Survey. “We are anticipating significantly lower runoff compared with the snowpack because we entered winter with such dry conditions that the soils are going to have to soak up a ton of moisture before it actually makes it through the system into the river.”
The Colorado Basin River Forecast Center and NRCS both released streamflow forecasts this week for the months of April through July. This is the second year in a row parched soils will rob rivers of their water.
If soils were not so dry, streamflow predictions would track closely with snowpack. But this year, in many areas streamflows are predicted to be down by 15% to 20% compared with the snowpack, and streamflow for all river basins in the state are predicted to be below average.
NRCS relies heavily on data from SNOTEL (short for snow telemetry) sites for its water supply forecasts. These automated sensors collect snow and weather data from remote, mountainous areas around the state. At the beginning of the month, the snow-water equivalent, which is a measure of how much water is contained in the snowpack, was 90% of average for the Colorado River headwaters, which includes the Roaring Fork River basin. Warm weather the first few days of the month had dropped that number to 78% by Wednesday.
According to NRCS models, streamflow for the Roaring Fork River, measured at its confluence with the Colorado River in Glenwood Springs will be 70% of average. The CBRFC model predicts just 68% of average. Throughout the Colorado headwaters, streamflow predictions range from 57% to 77% of average.
According to CBRFC hydrologist Cody Moser, most river basins in Colorado were in the bottom five driest years for soil moisture going into the winter and some places, like the San Juan River basin in the southwest corner of the state, had record low soil moisture.
“We had poor soil moisture entering the season,” Moser said. “We also have below normal snow, so a lot of things are working against a good runoff season.”
The Lake Powell inflow forecast, at 3.2 million acre-feet, is just 45% of normal and a 2% decrease from the CBRFC March forecast.
Another tricky year for Ruedi
Tim Miller, a hydrologist at the Bureau of Reclamation, which operates Ruedi Reservoir, said predicting inflow into the reservoir from the Fryingpan River and surrounding tributaries is like “looking out into the crystal ball.”
It’s Miller’s job to release enough water from the reservoir to make room for the inflow. Filling it to capacity — roughly 102,000 acre-feet — requires precision and can be tricky. Last year Miller missed the mark by about 5,000 acre-feet, leaving reservoir levels a bit low. It was because streamflow forecasts didn’t fully account for the spring’s lack of precipitation, warmer-than-normal temperatures and dry soils, he said.
“We were over-forecasting until right at the very end,” Miller said. “It wasn’t until the end of May and early June that we realized we just weren’t going to get that volume. Last year, because of those forecasts, I was releasing quite a bit more water at this time because I was expecting a bigger inflow.”
This year, Miller said he plans on releasing just the minimum needed to meet the instream flow needs of the lower Fryingpan until he knows there will be enough runoff to fill the reservoir. Much of the water stored in Ruedi is either “fish water,” released for the benefit of endangered fish downstream or contract water, which has been sold by the bureau to cover the costs of building and operating the reservoir. Many different entities and water providers, including Ute Water Conservancy District and the Colorado Water Conservation Board, own some of this contract water.
The reservoir has a decent chance of filling this year, Miller said, but there is another factor that could negatively impact those chances. Ruedi is currently 57% full, down from where it was at this time last year, about 66% full, according to Miller.
“Ruedi is lower starting out than what it would have been starting out last year, so that’s going to be an issue,” Miller said. “There are just a lot of things to juggle.”
The bureau is predicting about 112,000 acre-feet of runoff for the upper Fryingpan River basin this year, but about half that will be taken through the Boustead Tunnel system to the Front Range, Miller said.
So how might low runoff affect local water providers and users? For starters, the city of Aspen is still in Stage 2 drought restrictions, a carry-over from last August. That means restrictions on washing sidewalks and vehicles, and outdoor watering. One of the biggest water uses in Aspen is outdoor watering of lawns and landscaping.
“We are going to do our damnedest to make sure people are responsible,” said Steve Hunter, utilities resource manager with the city of Aspen.
Hunter said he has been talking with other local water managers about creating a valley-wide unified message about the drought, to target residents and visitors alike. The next city drought response committee meeting is April 23.
Despite the bleak streamflow outlook, weather is still a big unknown. Late spring storms and summer monsoon season — which mostly failed to materialize in 2020 — could begin to turn things around.
“We are just going to be prepared,” Hunter said. “We need to be adaptable. It may get worse, it may get better, it may stay the same.”

Ruedi Reservoir release will increase tomorrow morning by approximately 14 cfs. The flow at the Fryingpan River gage below Ruedi Reservoir will increase from 46 cfs to 60 cfs for the next two months. The release increase is due to a contract release, and the goal is to mitigate formation of anchor ice within the Fryingpan River channel.
Dignitaries from throughout the nation, including U.S. Secretary of the Interior David Bernhardt and Bureau of Reclamation Commissioner Brenda Burman, gathered at Lake Pueblo for the groundbreaking of a pipeline that will deliver clear water to the Lower Arkansas River Valley…
As the conduit will bypass the Arkansas River, including the portion on Pueblo’s lower East Side where the heavily polluted Fountain Creek dumps into the river, it is seen as a regional solution to drinking water quality problems facing rural communities of Southeastern Colorado…
It may be a decade or more before the conduit will be built, but the project is well on its way now.
When completed, the conduit will serve an estimated 50,000 people in Southeastern Colorado via some 260 miles of pipeline.
Bill Long, president of the Southeastern Colorado Water Conservancy District and former Bent County commissioner, said: “It’s kind of an emotional event because generations have actually worked on this project and to finally see this kind of progress where we can deliver safe water to folks, which also provides a great opportunity for economic development is close to unbelievable. It truly is a great day.”
John Singletary, former chairman of the Lower Arkansas Valley Water Conservancy District, agreed:
“As a young boy in the Arkansas Basin, I sold gold frying pans to support the effort that eventually lead to President Kennedy coming to Pueblo to sign the Fryingpan-Arkansas Project into a law,” Singletary said. “This was the first step in seeing the Arkansas Valley Conduit built. In the decades since, people like Senator Michael Bennet have never lost sight that this project is more than politics. The Conduit is a vision turned reality to help reduce dry-up of farm ground and provide clean drinking water for 50,000 people in 40 communities east of Pueblo.”
The total project cost is estimated at somewhere between $564 and $610 million to complete over a 15-year period and about $30 million a year for the next 15 years will need to be appropriated to see it finished.
Sen. Michael Bennet, D-Colorado, who also has spent a lot of time and effort on the project throughout his career, echoed Long’s comments about ground finally being broken for the conduit.
“It is a testament to the commitment of generations of people in the Lower Arkansas Valley to bring clean drinking water to communities that were promised it in the early ’60s and never had that promise fulfilled,” Bennet said. “One of the first things I heard about when I became a senator was the Arkansas Valley Conduit because of Bill (Long) and because of Ray Kogovsek, who had been the congressman for that area, and made the case about how important it was.”
Bennet said the progress made on getting the conduit built has been a true bipartisan effort in which Democrats and Republicans have worked hand-in-hand…
The conduit, part of the original Fryingpan-Arkansas Project, would bring water from Pueblo Dam to Lamar and Eads, serving about 40 communities along the route. As it will bypass the Arkansas River, including the portion on Pueblo’s lower East Side where Fountain Creek dumps into the river, it is seen as a regional solution to drinking water quality problems facing rural communities of Southeastern Colorado.
Many of those water providers are facing enforcement action for high levels of naturally occurring radionuclides in well water. A new source of clean water through the Arkansas Valley Conduit is the least expensive alternative, according to a 2013 Environmental Impact Statement.
While the project is breaking ground, there is still a long way to go, Bennet cautioned.
The total project cost is estimated at somewhere between $564 and $610 million to complete over a 15-year period and about $30 million a year for the next 15 years will need to be appropriated to see it finished.
“It’s not going to be easy to do but we’re going to fight for it,” Bennet said.
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.
Available information concerning the purpose of the acquisition and the degree of preservation and improvement of the natural environment, and available scientific data is available at:
Ruedi Reservoir is feeling the effects of an unusual water year, with less water for endangered fish and with low reservoir levels predicted for late summer and fall.
“This year was a strange year,” Tim Miller, a U.S. Bureau of Reclamation hydrologist who manages operations at Ruedi, said at an annual public meeting about reservoir operations held virtually Wednesday. “For most of the year, it seemed like we were doing well, we thought we would get a fill on the reservoir. However, things really turned around in late spring and early summer.”
At the meeting convened by the Bureau of Reclamation, Miller said the reservoir, which holds just over 102,000 acre-feet of water, topped out at 96,750 acre-feet this year — about 5,000 acre-feet short of filling. That means there is 5,000 acre-feet less water available this season to boost flows downstream for endangered fish in what’s known as the “15-mile reach” of the Colorado River near Grand Junction.
As reservoir levels continue to drop over the next month, Aspen Yacht Club members may not be able to access the boat ramp over Labor Day weekend. By Sept. 1, reservoir levels are predicted to be down to about 84,500 acre-feet and the surface to be at an elevation of 7,747 feet, which is 19 feet lower than when it’s full.
“After Sept. 1, it’s going to be dicey,” Miller said of accessing the private marina’s boat ramp. The U.S. Forest Service boat ramp will still be accessible at those levels, he said.
Bruce Gabow of the Aspen Yacht Club said that when water levels are 13 feet below full, the club’s docks become grounded and inoperable. He said that most years, boats are taken out of the reservoir by mid-September, but with water levels dropping sooner this year, many will need to go before the end of August.
“Everyone has kind of been expecting it, but they will be bummed out,” he said of the club’s members.
Ruedi Reservoir is currently 92% full, at 94,065 acre-feet. It topped out on July 17 at 96,914 acre-feet. In 2018, the reservoir also didn’t fill, topping out at 92,650 acre-feet, according to Miller.
Each spring, Miller must decide how much water to release from Ruedi and when to release it to make room for inflow from snowmelt. Those decisions are based on streamflow forecasts from the Colorado Basin River Forecast Center and the Natural Resources Conservation Service, as well as the Bureau of Reclamation’s statistical forecasts.
This year’s unusual conditions made for tricky forecasting, leading some to question whether more and better data collection is needed, instead of relying primarily on snow telemetry, or SNOTEL, data. These automated remote sensors collect weather and snowpack information in remote watersheds, but they provide only a snapshot of a specific location. Each of the three forecasting agencies over-predicted Ruedi inflow for the months of April, May and June.
Usually, the amount of runoff closely mirrors snowpack. And with snowpack in the Roaring Fork River basin slightly above normal, as measured by SNOTEL sites, it seemed that is where runoff would also end up. But parched soils from a dry fall sucked up some of the moisture before it made its way to streams and eventually the reservoir. Miller also suspects that a high rate of sublimation — where snow goes from a frozen state to vapor, skipping the liquid phase — may have also played a role.
“To do our statistical forecast, it’s 90% snowpack only,” Miller said. “We had some different variables this year.”
By the end of May, Miller realized inflow projections were too high and began scaling back releases. Ruedi also did not participate in Coordinated Reservoir Operations this year. In the annual CROS, which began around May 29, water managers from across the state aimed to enhance peak spring runoff by releasing water from reservoirs at the same time. The peak flows have ecological benefits, especially for fish in the 15-mile reach.
“It was pretty much a last-minute declaration we couldn’t do CROS,” Miller said.
April Long, executive director of Ruedi Water & Power Authority, suggested that water managers should explore other ways of collecting data in addition to SNOTEL information to improve forecast accuracy. The city of Aspen and Denver Water have experimented with LiDAR technology — which analyzes the reflection of laser light to create detailed three-dimensional maps — to track the depth of mountain snowpack, providing a more complete picture of the water contained in that snowpack.
“With this year of unexpected results from our snowpack and the way it melted off, I have concern that with climate change and climate variability, we are going to see more uncertainty,” Long said in a follow-up interview with Aspen Journalism. “I wonder how much benefit we could gain if we knew a little more.”

Here’s the release from the Colorado Water Trust, et al. (Mark Harris, Mark Harris, Donald Anderson, and Scott McCaulou):
On Saturday, August 1, Colorado Water Trust, Grand Valley Water Users Association, and Orchard Mesa Irrigation District will initiate their implementation of an agreement that will deliver 877 acre-feet of water to the Grand Valley Power Plant and the 15-Mile Reach of the Colorado River above its confluence with the Gunnison River near Grand Junction, Colorado this summer. Grand Valley Water Users Association and Orchard Mesa Irrigation District identified available capacity in their water delivery system for Colorado Water Trust to deliver water decreed for power generation through the Grand Valley Power Plant, from where it subsequently returns to the 15-Mile Reach. This delivery will mark the second execution of an innovative agreement that Colorado Water Trust, Grand Valley Water Users Association, and Orchard Mesa Irrigation District entered last year with assistance from the Upper Colorado Endangered Fish Recovery Program and the Bureau of Reclamation.
The agreement furthers common goals of streamflow restoration for the 15-Mile Reach and takes steps toward unlocking a $425,000 grant from Walton Family Foundation to renovate the aging Grand Valley Power Plant. Thanks to donor support, Colorado Water Trust has purchased stored water from the Colorado River District. That water will be released from Ruedi Reservoir to the Colorado River for use in the power plant and to increase 15-Mile Reach flows to support four species of endangered fish including the Colorado Pikeminnow, Humpback Chub, Bonytail, and Razorback Sucker.
“We are so grateful to Grand Valley Water Users Association and Orchard Mesa Irrigation District for coordinating with us to boost flows in the 15-Mile Reach. Seeing the project work for a second year in a row proves the lasting success of our partnerships, and it’s particularly important to the fish this year, with flows as low as they are.” says Kate Ryan, Senior Staff Attorney for Colorado Water Trust.
This is the second time in the past two summers that Colorado Water Trust purchased water stored in Ruedi Reservoir for release to the 15-Mile Reach of the Colorado River to help maintain healthy streamflow and water temperatures. Purchases since 2019 will result in delivering over 1200 acre-feet of water to the Colorado River. Colorado Water Trust works closely with Grand Valley Water Users Association and Orchard Mesa Irrigation District to identify when there is available capacity in the power plant. Colorado Water Trust also works closely with the Upper Colorado River Endangered Fish Recovery Program to determine when the 15-Mile Reach needs supplemental water most to support the fish. When these two conditions overlap, Colorado Water Trust releases the water purchased out of storage for delivery to the power plant and then the 15-Mile Reach.
“Orchard Mesa Irrigation District and the Grand Valley Water Users Association appreciate the Colorado Water Trust’s facilitation of this agreement–it benefits our two organizations at the Grand Valley Power Plant, and the many other water users who support flows through the 15-Mile Reach. We believe these kinds of collaborative efforts to be of great value to the people of Colorado, the Colorado River, and the fish,” says Mark Harris, General Manager of Grand valley Water Users Association.
“Maintaining adequate flows for endangered fish through the 15-Mile Reach is possible only because of the extraordinary cooperation our Recovery Program enjoys from multiple partners and stakeholders. We are delighted to add the Colorado Water Trust to that mix of cooperators. This year, in light of unusually low flow conditions in the Colorado River, the additional water made available through this leasing arrangement is especially welcome,” says Donald Anderson, Hydrologist and Instream Flow Coordinator for the Upper Colorado River Endangered Fish Recovery Program.
The Roaring Fork Conservancy also helps to inform Colorado Water Trust of conditions on the Fryingpan and Roaring Fork Rivers to so that releases will complement flows on the stream sections between Ruedi Reservoir and the Colorado River. This year, the water released from Ruedi Reservoir will serve a few purposes before it supports the health of endangered, native fish in the Colorado River in the 15-Mile Reach. The water will bring flows in the Fryingpan River closer to their average, and will cool water temperatures on the Roaring Fork River. Finally, on the Colorado River, the water will generate hydropower, helping to produce clean energy.
“Flowing rivers are an economic engine in Colorado, providing immense value to irrigators, drinking water providers, and recreation across the state,” says Todd Reeve, CEO of Bonneville Environmental Foundation and Director of Business for Water Stewardship. “It is for this reason that we are seeing more and more corporate funders step forward to invest in innovative projects like this one that help keep the rivers in Colorado flowing.”
Essential to the project’s success are dedicated donors: Bonneville Environmental Foundation, Coca Cola, Colorado Water Trust donors, and Daniel K. Thorne Foundation. Without these generous donations and the collaborative work of local and state agencies, water releases to support the health of the 15-Mile Reach of the Colorado River would not be possible.
ABOUT COLORADO WATER TRUST: Colorado Water Trust is a statewide nonprofit organization that works collaboratively with partners all across Colorado on restoring flow to Colorado’s rivers in need using solutions that benefit both the people we work with and our rivers. Since 2001, we’ve restored 12 billion gallons of water to rivers and streams across the state.

Construction of the Arkansas Valley Conduit is expected to begin in the near future following the state’s approval of a $100 million financing package for it.
The Colorado General Assembly has approved the annual Colorado Water Conservation project bill that contains the funding, and Gov. Jared Polis signed that bill into law earlier this week…
The Arkansas Valley Conduit is estimated to cost between $564 and $610 million to complete over a 15-year period, according to Chris Woodka of the Southeastern Colorado Water Conservancy District.
The $100 million in state funding would include $90 million in loans and $10 million in grants over the life of the project. When complete, the conduit will provide clean drinking water to 50,000 people in 40 communities.
The conduit had received funding since 2010 to prepare for construction of the 130-mile pipeline which will deliver a safe drinking water supply to the Lower Arkansas Valley.
In February, the Bureau of Reclamation announced that $28 million of fiscal year 2020 funding was being directed to the conduit in an effort to move from planning and design into construction. An additional $8 million has been requested for fiscal year 2021 and is under consideration by Congress, Woodka said.
Pitkin County has approved funding for a study that aims to protect recreational flows in the Roaring Fork and Crystal rivers, and how future water development projects and climate change might affect those flows.
At a meeting earlier this month, Pitkin County commissioners approved a recommendation from the county’s Healthy Rivers Board to fund the $19,355 proposal from American Whitewater. The project includes an extensive survey of river users — specifically boaters — about what flows are optimal for certain popular river segments.
Kayakers, commercial river outfitters, stand-up paddleboarders and anyone else who runs local rivers can weigh in with their flow preferences for popular reaches of the Roaring Fork like North Star, Slaughterhouse, Toothache and the river below Basalt. They will also ask about the Crystal River, which gets less recreational traffic than the Roaring Fork, but has some well-known stretches, like the Narrows and Meatgrinder, which are favored by experienced kayakers, and the more accessible reach from Avalanche Creek to the BRB campground.
The lower Roaring Fork is increasingly popular with anglers, but this survey will focus on boating, both commercial and private.
Once American Whitewater determines what flows boaters prefer, the organization will use its “boatable days” tool, which compares the flow preferences to the historic river hydrology to see if and when the flow preferences are met and how that might change in dry or wet years.
“It allows us to actually quantify river recreation opportunities so it can be used to inform water management decisions and understand future impacts,” said Kestrel Kunz, Southern Rockies stewardship assistant for American Whitewater. “We can see how climate change might affect the number of boatable days in the valley.”
According to a report by the Colorado River Outfitters Association, the economic impact of commercial boating on the Roaring Fork in 2019 was $4.8 million. The economic impact statewide was $188 million. But despite the size of its contribution to the economy, recreation is an area often overlooked by traditional water planning and management, according to Pitkin County Healthy Rivers Board Chair Andre Wille.
“Recreation seems to really get the short end of the stick when it comes to streamflow management,” Wille said. “I think water managers in the Roaring Fork area and in a lot of other Western Slope rivers, the water managers are all about irrigation and recreation isn’t really taken into as much consideration as it should be, especially considering the economic impact of recreation and the importance to the citizens.”
About 40% of the headwaters of the Roaring Fork and Fryingpan rivers is sent to Front Range fields and cities — including Aurora, Colorado Springs and Pueblo — through transmountain diversions. When the Twin Lakes tunnel underneath Independence Pass ratchets its intake up or down, it can affect boating conditions downstream on the Roaring Fork and diversions out of the Fryingpan can affect flows on the lower Roaring Fork.
The information collected in the survey could help water managers better plan when and how much water to divert.
“It’s just a chance to get some data from recreation users and it would be nice if water managers would take that into consideration,” Wille said. “There might be other stream management strategies that are beneficial to the Roaring Fork. There might be a better way to manage filling (Twin Lakes) reservoir.”
The survey, which will be available on the American Whitewater and Pitkin County Healthy Rivers websites and local paddling forums, will ask boaters about their skill level, frequency of participation and craft type. The survey will allow boaters to assign use-acceptability ratings to various streamflows and ask them for their perspectives on water management planning. American Whitewater aims to collect at least 150 surveys each from boaters on the Roaring Fork and Crystal rivers.
James Foerster, owner of Aspen-based rafting company Elk Mountain Adventures, said he’s excited to see the county focusing on recreational boating. The company is one of three, along with Blazing Adventures and Aspen Whitewater that run trips on the Roaring Fork.
Foerster’s company runs what they call “adventurous” rafting trips from Cemetery Lane to Jaffee Park in Woody Creek on the Slaughterhouse section of the Fork, as well as “family-friendly trips” from Jaffee Park to Wingo Junction above Basalt on the Toothache section and from Hooks Spur Bridge, near the Fed Ex outlet by Willits, down the river to the Catherine Store Road bridge above Carbondale.
He says guides will change the put-in and take-out locations to adapt to changing flows as the season goes on.
“I think every commercial outfitter would tell you more water is better,” Foerster said. “I think what it really comes down to is the flows we get coming through Aspen in late July and August, they are unsustainable. And the lower Crystal as well, mainly because of diversions and ditches.”
Carbondale-based Lotic Hydrological will develop the survey. The findings will be synthesized and presented as technical reports by December 2020.

The Southeastern Colorado Water Conservancy District and U.S. Bureau of Reclamation recently adopted a project management plan that will guide construction of the Arkansas Valley Conduit…
Terry Scanga, general manager of the Upper Arkansas Water Conservancy District, said he didn’t see the AVC having much impact on Salidans and others in the area. “It’s not going to change river flows,” he said. “It’s not going to impact the allocation (of water) communities in the upper basin get.”
After thinking about it for a second he said some transit loss might have a “minimal impact” on irrigators, but added that the advantages of the project far outweigh those potential effects.
[Sam] Braverman said they’re not creating any new water diversions from Colorado’s Western Slope. The big change, he said, is that water will now be piped from Pueblo to surrounding municipalities instead of letting it flow to them in the river, which will improve drinking water quality…
Salinity, selenium and uranium found in the natural environment all pose water-quality challenges for the Arkansas River in southeastern Colorado.
Several communities the conduit will serve currently can’t drink their tap water.
“There’s at least 5,000 people who literally have radioactive water coming out of their pipes,” Braverman said. “They can’t drink their water, and (the municipalities) can’t afford to filter it out.”
Braverman said another 11,000-12,000 people in the communities get their water from reverse osmosis, but the state doesn’t see those systems as permanent solutions because they put their effluent back into the river. He said drying the effluent, packing it and taking it to landfills would be too costly to be a realistic solution.
“There’s no way those communities could afford to do that,” he said. “The AVC is really the only answer for all of these communities; this a game changer for disadvantaged areas.”
The AVC will provide water for municipal and industrial use.
The project management plan describes how the project will be executed, monitored and controlled.
Under the plan, the Pueblo Board of Water Works will deliver AVC water to a point east of Pueblo. A contract among the Reclamation Bureau, Pueblo Water and Southeastern Colorado Water Conservancy District is in the discussion stage. From that point, the bureau will construct the trunk line, a treatment plant and water tanks, while Southeastern will coordinate with communities to fund and build connections.
Southeastern will serve as lead on the “spur and delivery lines” portion of the project and seek funding to design and construct this portion of the project, $100 million of which has already been secured from the Colorado Water Conservation Board, subject to legislative approval.
Braverman said they just started final design on the first 12 miles of the pipeline…
Braverman said communities the AVC will serve have been hearing about it for decades, but getting the $28 million recently was the first chunk of money they’ve secured to begin construction.
“That was a complete shift from where we were,” Braverman said. “Now it’s just a matter of the funding stream continuing.”
The release from Ruedi Reservoir will increase Friday afternoon by 25 cfs. The flow at the Fryingpan River gage below Ruedi Reservoir will change from 135 cfs to 160 cfs where it will remain for the near future.
For any concerns regarding Ruedi Reservoir operations please contact either Brittany or Elizabeth Jones at (406) 247-7611 or (406) 247-7618.
Friday, April 03 2020, 1400 hrs
Increase the reservoir release by approximately 25 cfs (carried out by High Country Hydro, Inc. personnel). After this change, the flow at the Fryingpan River gage below Ruedi Reservoir is expected to increase from 135 cfs to approximately 160 cfs, with a gage height of 1.76 feet.
Through the release of water it owns in Ruedi Reservoir, Garfield County will help endangered fish species in an often-depleted section of the Colorado River.
Garfield County will lease 350 acre-feet of water annually over the next five years to the Colorado Water Conservation Board under the CWCB’s instream-flow program. The water will bolster flows July through October in the 15-mile reach of the Colorado River near Grand Junction, home to the endangered humpback chub, bonytail, razorback sucker and Colorado pikeminnow. The CWCB board approved Garfield County’s offer at its meeting last week in Westminster.
Garfield County owns 400 acre-feet a year of Ruedi water as a backup source for the county, municipalities and other water users within its service area. Since the county does not immediately need the water, it will lease the water to the CWCB for five years at $40 an acre-foot for the first year and $45 an acre-foot for the second year. The price would go up in years three through five by 2% annually. The maximum price the CWCB would pay for the water is $14,000 in 2020 and $78,915 over the five years of the lease.
Water from Ruedi Reservoir flows down the Fryingpan River and into the Roaring Fork, which flows into the Colorado River at Glenwood Springs.
“We are really appreciative that Garfield County stepped up and offered to lease the water,” said Linda Bassi, CWCB’s stream- and lake-protection chief. “You never know what kind of water year we are going to have, so it’s great to have an extra supply to send down to the reach for those fish.”
Preserving Fryingpan fishing
Late summer, flows in the 15-mile reach are often lower than what is recommended by the U.S. Fish and Wildlife Service for healthy fish habitat mainly because of two large upstream irrigation diversions: DeBeque Canyon’s Grand Valley Project, known as the Roller Dam, and Palisade’s Grand Valley Irrigation Canal.
Gail Schwartz, who represents the Colorado River mainstem, Fryingpan and Roaring Fork region on the CWCB board, reminded staffers of the need to coordinate flows out of Ruedi to preserve conditions for anglers. When flows exceed about 300 cubic feet per second, it becomes difficult to wade and fish the Fryingpan’s popular Gold Medal Fishery waters. At critical wading flows of 250 to 300 cfs, Colorado Parks and Wildlife recommends releases be capped at 25 cfs to avoid dramatic changes for anglers.
“We want to support the economy and the recreation on the Fryingpan and we want to support the success of the 15-mile reach for the species,” Schwartz said.
More fish water
At its March meeting, the CWCB board will consider another lease of Ruedi water for endangered fish. The Ute Water Conservancy District, which provides water to about 80,000 people in the Grand Junction area, is offering to renew its lease of 12,000 acre-feet of water it stores in Ruedi Reservoir. The CWCB could lease the water at $20 an acre-foot for 2020, at a total cost of $240,000.

On a recent, clear, cold Saturday morning, local students from Carbondale-based Youth Water Leadership Program packed into a six-seat, single-engine Cessna 210 piloted by Gary Kraft of EcoFlight.
From the cockpit and high above the Roaring Fork watershed, certain features jumped out — the long, straight line of Red Mountain Ditch cutting across the hillside; infrastructure of the Twin Lakes Reservoir and Canal Co. siphoning water to the Front Range; the ponds that feed Aspen Skiing Co.’s snowmaking system; and the glittering surface of Ruedi Reservoir.
One goal of the flight was to give students a firsthand experience of natural resources — in this case, rivers and water. Aspen-based EcoFlight flies policymakers, students and journalists over Western landscapes to highlight man-made impacts to the natural world.
“The best way to teach people about places is to get them in the places,” said Sarah Johnson, watershed-education specialist and founder of the Youth Water Leadership Program.
The plane took off from the Aspen airport, gaining altitude as it flew up Independence Pass to the headwaters of the Roaring Fork, down the Fryingpan River valley, around the white flanks of Mount Sopris and up the Crystal River valley before cruising past the Maroon Bells and Aspen Mountain back to the airport.
How humans modify water
Also evident from the air were the burn scars from 2018’s Lake Christine Fire on Basalt Mountain, as well as the many large homes near Aspen with ponds on the property. For Coal Ridge High School senior and youth-water program leader Aidan Boyd, it was striking to see the patterns of land use in the valley.
“It is really interesting to compare the remote mountains that seem completely untouched to as you get more into the towns it’s just a very different feeling,” he said. “We’ve talked a little bit about how a lot of really wealthy houses will modify water — houses with lakes and pools. It was really interesting to see that.”
From 13,000 feet, it also became apparent just how near to one another are the headwaters of the watershed’s three main tributaries: the Roaring Fork, Fryingpan and Crystal rivers — something that isn’t evident when one travels the region by car. All three begin as trickles in close proximity, high among the 14,000-foot peaks of the Elk and Sawatch ranges.
“I never really realized how close everything is to each other because I’ve always driven up to Aspen and Basalt,” said Isla Brumby-Nelson, an eighth-grader at the Waldorf School on the Roaring Fork.
Youth Water Leadership Program
The goal of the Youth Water Leadership Program is not only to increase students’ knowledge of their local watershed and Colorado River issues, but also to create student-driven, call-to-action projects. Students will present these projects — on topics that range from how drought affects small farmers to microplastics and desalination — at the annual Youth Water Leadership Summit in December.
The invitation-only event is sponsored by Pitkin County Healthy Rivers and Streams. Representatives from the Colorado Water Conservation Board, the Colorado River Water Conservation District, Colorado Parks and Wildlife, and Sen. Michael Bennet’s office have already confirmed they will attend.
“The program is about teaching young people how to participate in public life,” Johnson said.
The Saturday field trip culminated with a tour of the Snowmass Water and Sanitation District and Zeigler Reservoir. But the bird’s-eye view of the watershed that students experienced with EcoFlight is the experience that is most likely to stay with them, Johnson said.
“I think that perspective is eye-opening,” she said, “when you start to see all the ditches and diversions, man-made lakes versus natural lakes and how many more water-storage structures there were than we thought. … They are going to have this reference point and bring that into the conversation, and I think that is powerful.”

Lessons learned from an Aug. 4 flash flood on the south side of Basalt Mountain educated a consortium of governments on what needed to be done to try to avoid a repeat performance.
A contractor for the town of Basalt is working at the intersection of Cedar Drive and Pinon Drive in the Hill District to better handle water spilling out of the Lake Christine burn scar…
He credited the Natural Resources Conservation Service, a federal agency, for looking at the road intersection and adapting a flood mitigation plan. The NRCS had to sign off on all work performed after the federal government awarded a $1.23 million Emergency Watershed Protection Program grant earlier in the year to Basalt, Eagle County and Colorado Parks and Wildlife.
A large catch basin that Eagle County sculpted into the mountainside above Basalt in recent weeks prevented significantly more water, mud and debris from swamping part of the Hill District during [the August 4, 2019] flash flood, officials said Thursday.
Eagle County Road and Bridge Department used heavy equipment to dig out a settlement pond and then used the dirt removed to regrade the hillside above the Basberg Townhouses. Boulders were placed in two drainage channels that led the water to the settlement pond. While water topped the pond during Sunday’s downpour, a lot of it was captured. Thick, sludge-like water was still in the pond Thursday.
This summer, the town of Basalt also created berms, added curb and gutter and installed a swale to direct water, all just uphill from the Basbergs…
The work was part of a $1.35 million Emergency Watershed Protection Program project. The federal government supplied a $1.23 million grant through the Natural Resources Conservation Service. The state of Colorado contributed $153,359. Basalt, Eagle County and Colorado Parks and Wildlife are undertaking in-kind projects valued at $153,359, or 12.5%, to cover a local match.
The grant was administered by Basalt. Projects were identified by the Natural Resources Conservation Service. Engineering was provided by SGM, a consultant for Basalt town government.
Basalt Town Manager Ryan Mahoney said about 20% of the work has been completed. Additional projects have been identified above Basalt, on the hillside overlooking Ace Lane’s Tree Farm property in El Jebel and on Basalt Mountain where it drops steeply to Upper Cattle Creek where several historic cabins are located.
Mahoney said he felt work performed at and around a culvert at the intersection of Pinon and Cedar drives in the Hill District also softened the blow of the flash flood.
The town widened the area around the entrance to the culvert but it was still overwhelmed by the amount of water roaring down from a usually dry gulch on the mountain.
“We’ve got some river pigs — big concrete blocks — at the bottom of the drainage,” he said. “Those are to hold debris back.”
Governments teamed to install three rain gauges on Basalt Mountain so the risk of flash flooding can be better assessed in the future. Those rain gauges were calibrated this week to ensure accurate readings.
In addition, National Weather Service meteorologists visited Basalt Mountain with local emergency responders this week to get a better feel for the lay of the land. Thompson said Sunday’s storm demonstrated that different sections of Basalt Mountain can experience vastly different weather.
The projects funded through the Emergency Watershed Protection Program will continue through the summer and into fall. All told, work will be undertaken in nine drainages, Mahoney said.
A storm that unleashed its power over the Lake Christine burn area beginning late Sunday afternoon triggered multiple debris flows and water on Frying Pan Road that temporarily trapped 20 different vehicles, but resulted in no known injuries, according to Scott Thompson, chief of Roaring Fork Fire Rescue…
A Pitkin Alert evacuation notice went out at 5:31 p.m. aimed at those who lived in the area of Pinon Road and Cedar Drive imploring them to “please take all necessary precautions,”which included seeking higher ground. “Do not enter flowing water or debris,” was among the initial warnings.
Frying Pan Road was closed intermittently Sunday from Riverside Drive to about 2 1/2 miles up the road, according to deputy chief Cleve Williams. The intersection of Cedar Drive and Two Rivers Road was reopened by 10 p.m. on Sunday…
According to the National Weather Service in Grand Junction, an inch of rain fell over the first hour, beginning at 5 p.m. There were reports of heavy rain after the first 30 minutes and flooding started on the south end of the Lake Christine burn scar. By 8:30 p.m. the rain had subsided and, according to Chief Thompson, was expected to let up before midnight.
FromThe Aspen Times (Rick Carroll) via The Glenwood Springs Post Independent (Click through to view the photo gallery):
One of the trigger points for the floods was at Pinon Drive and Cedar Drive, an area above Basalt from where the initial 911 calls were placed at approximately 5:30 p.m. Sunday…
All of the roads, including Frying Pan Road — where 10 vehicles had been stuck Sunday and later removed — had re-opened to traffic by Monday. Pinon and Cedar drives, as well as Two Rivers Road, also had been closed. Two Rivers Road opened late Sunday; Pinon and Cedar opened Monday morning.
Crews also on Monday determined the floods had not damaged the integrity of roads and bridges, said Birch Barron, Eagle County emergency manager.
Structural damage to the residences in the affected area appeared to be limited, according to Barron.
“We believe there were less than 10 private residences with debris in or around structures, and for the majority of those structures, the debris was in nonresidential spaces — garages and basement and property surrounding that,” he said.
The county had not received any reports of residences being uninhabitable, Barron noted.
The evacuation zone impacted about 30 residences; however, a number of individuals couldn’t evacuate because of dangerous road conditions, Barron said.
Sunday’s response was a collaborative effort among Eagle and Pitkin counties, the town of Basalt, area law enforcement and emergency response teams, as well as state and federal agencies, Barron said.
The flow out of Ruedi Reservoir was increased Monday by 50 cubic feet per second to help clear up the Fryingpan River, which had taken on a muddy hue from the flood’s debris and sediment.
“This should be a big help toward protecting fish and river health,” said Kris Widlak, Eagle County’s director of communications.
Here’s the release from the Bureau of Reclamation (Tyler Johnson):
The Bureau of Reclamation has scheduled the annual public meeting to discuss the Ruedi Reservoir Water Operations for the 2019 water year.
The meeting will be held on August 7, 2019, from 6:30-8:00 pm at the following location:
Roaring Fork Conservancy River Center
22800 Two Rivers Road
Basalt, CO 81621
The meeting will provide an overview of Ruedi Reservoir’s 2019 projected operations for late summer and early fall, which are key tourist seasons in Basalt. Also, representatives of the Colorado Water Conservation Board and the U.S. Fish and Wildlife Service will give a presentation on the upcoming implementation of the Ute Water Conservancy District lease of Ruedi Reservoir water to the Board for instream flow use in the 15-Mile Reach of the Colorado River. The meeting will include a public question and answer session.

A flood advisory has been issued for all major rivers in the Roaring Fork watershed by the National Weather Service. The advisory is in effect until further notice.
According to a report issued Wednesday by the Roaring Fork Conservancy, the rivers in this watershed are currently flowing at more than twice the average for this time of year.
On Monday, the Roaring Fork River at Glenwood Springs hit 9,030 cubic feet per second, which is the biggest peak of 2019, according to RFC’s report. While flows have declined slightly since July 1, they are expected to surge over the next week, the report continued.
The Fryingpan River below Ruedi Reservoir was measured at 950 cfs on Wednesday, according to the RFC.
Basalt Police Chief Greg Knott said in his six years at the helm, he’s seen the Fryingpan River hit 950 cfs just one other time, which was in 2016.
Both Ruedi and Twin Lakes reservoir are expected to fill to capacity in the coming days.
“These elevated flows will cause the Fryingpan River to remain above bankfull levels,” according to the NWS. “Minor lowland flooding can be expected along the river.”
The July 3 report from RFC showed the Roaring Fork River in Aspen at 747 cfs and at a whopping 4,370 cfs in Basalt below the confluence with the Fryingpan River.
As the flow in the Roaring Fork River at the Basalt whitewater park has climbed over 2,500 cubic feet per second this week, the park’s two “play” waves, produced by concrete structures embedded in the river, are still proving capable of flipping rafts and sending people for long, cold swims.
The two structures, built in late 2016 and early 2017 by consultants and contractors working for Pitkin County, were re-engineered last winter after complaints by experienced local boaters that the artificial waves were hazardous.
But the low flows in 2018 did not provide a fair test to see whether the rearranged waves were still a menace for rafters.
With the return of more-typical high spring flows, the two waves — meant to be fun to surf at low water and located in a section of river not otherwise considered difficult to run — are showing they can still be a challenge even for experienced boaters.
3 of 9
On Sunday, three rafts in a group of nine boats piloted by noncommercial rafters, or “private boaters,” flipped in the upper of the two waves.
Both of the waves have steep drops that lead directly into a nearly riverwide wall of churning foam, save for narrow and hard-to-spot “sneaks” through relatively calm water on far river let, or the left side of the river looking downstream.
Emergency personnel from the Roaring Fork Fire Rescue Authority responded Sunday to a 911 call about the flipped rafts and numerous people in the river.
“One of the first boats, if not the first, flipped in that first wave, and it’s a keeper, and it didn’t let them out,” said Robert “Sardo” Sardinsky, a volunteer with the rescue authority and who was downstream of the incident and was relaying the information he was given. “So, all of a sudden, there is a bunch of people in the water. And then, two more rafts flipped. And it sounds like the boats were being held in there.”
Sardinsky helped retrieve two of the flipped rafts, several miles downstream of the whitewater park, and he also talked with a number of the boaters in the party.
He said the group included boaters from both the Roaring Fork and Eagle River valleys, and he described them as calm, knowledgeable, experienced and well-equipped, wearing both wetsuits and personal flotation devices.
“They all appeared to be quite capable,” Sardinsky said.
The river was flowing through the whitewater park on Sunday at 4 p.m. at about 2,800 cfs, which can be calculated by subtracting the flow of the Fryingpan River from the flow of the Fork as measured downstream of the whitewater park in Emma.
“In my 30 years with the fire department and swiftwater rescue, it is the most dynamic rescue we’ve had,” he said. “It was the most number of people in river spread out over the most distance. And it’s incredibly fortunate that everyone got out.”
Sardinsky said about a week before Sunday’s events, a woman he knows had fallen off a paddle board into the first wave, at lower water, and had been trapped in the wave’s circulating hydraulic. The woman escaped by diving down to the bottom of the river, out from under the wave.
All of the boaters thrown into the river on Sunday either self-rescued or were rescued by their fellow boaters. None of them required emergency personnel to fish them out.
According to Kyle Ryan, who also volunteers with the rescue authority and was helping to coordinate Sunday’s response, the rafts that flipped were normal-sized whitewater rafts with oar frames, and were not especially small or lightweight.
“They were normal-looking whitewater rafts,” he said. “And everyone seemed to be pretty well-experienced.”
Ryan said two members of the rafting party asked to be transported to the hospital, but he said they did not appear to be seriously injured.
Also on Sunday, a raft being run as a paddleboat by another group of experienced boaters flipped in the first wave of the whitewater park, throwing six people into the river for a “frigid and scary swim.”
According to a public post on Facebook by Mary Sundblom, she and the five other boaters, including at least one former raft guide, set out Sunday to paddle from Northstar, east of Aspen, to Glenwood Springs.
Along the way, they ran the Slaughterhouse section of the Fork below Aspen and the most technical part of the river, as well as the difficult Toothache section in Woody Creek before heading for Basalt.
She wrote that the group scouted the river before their run, “got intel from longtime river rats,” and had “great lines” and “no swims” through Slaughterhouse and Toothache.
“Then the Basalt ‘play’ wave got us, flipped the raft, dumping 6 of us in for a frigid and scary swim,” Sundblom wrote. “After floating through some big waves and getting tumbled over some shallow rocks … I was stoked to find myself next to my captain when the boat floated down to us after a few surfs of its own … where he was able to flip it back over and pull my ass in! Such a beautiful feeling of RELIEF!
“We all made it out just fine, slightly rattled, with a few bumps and bruises, but continued on. That’s how the river goes.”
Tyler Manchester, who grew up in the valley and has rowed the Colorado River through the Grand Canyon without difficulty, was in the boat with Sundblom on Sunday.
He said via text on Thursday that “we were told to sneak left, but it came up fast and we weren’t ready. We hit it a little sideways. Definitely got washing-machine tumbled in both (waves), but everyone was flushed immediately.
“Had to swim upstream to get the boat,” Manchester noted.
The Basalt whitewater park is located below the low Basalt “bypass bridge,” which crosses the Fork at the junction of upper Two Rivers Road, just upstream of downtown Basalt. Floating beneath the bridge is often dark and spooky, but the current does not usually send boats directly at the bridge’s pylons.
The whitewater park also can be described as being just below Fisherman’s Park, which has a small boat ramp, across from the entrance to Elk Run and upstream of the 7-Eleven in Basalt.
Pitkin County Attorney John Ely, who has overseen the development of the whitewater park for the county, said Wednesday that he was aware of the recent raft flips, and he’s in touch with the consultants at River Restoration in Carbondale who designed the structures, oversaw their re-engineering and have been keeping a close eye on this year’s emerging waves.
Ely said he didn’t yet have enough information to determine whether the county needs to ask the consultants to do more work on the structures in the river.
The county chose the location for the park in large measure because it is just above the Fork’s confluence with the Fryingpan River, making it a good place to establish water rights tied to the wave-producing structures. Such water rights are called recreational in-channel diversion, or RICD, rights.
County officials have said their highest priority in developing the park was to establish the recreational water rights, which carry a 2010 priority date, and that the resulting recreational experience was a secondary concern.
The water rights are tied to the design of the structures, which are supposed to create fun, recreational play waves at flows between 240 and 1,350 cfs. The river on Sunday in that section of river was flowing at about 2,500 cfs, which is not unusual for June.
At higher flows, the wave structures are not necessarily meant to produce fun play waves, but they also are not supposed to produce big keeper waves, either.
Aspen Journalism covers rivers and water in collaboration with The Aspen Times. The Times published this story on Thursday, June 20, 2019.
The Colorado River east of Grand Junction in DeBeque Canyon is forecast to hit its annual peak Saturday, in a quick climb to about 21,000 cubic feet of water per second, as measured at the Cameo gage, before dropping over the next week as cooler weather arrives.
The operators of five upstream reservoirs have been closely watching this season’s large, and late, spring-runoff pattern, and they are now starting a coordinated release of water designed to improve habitat for endangered fish in a 15-mile stretch of the river below Palisade.
The reservoir releases, which collectively will add about 1,300 cfs of water to the river, are being timed to reach Palisade on Monday or Tuesday, after this weekend’s peak flows have subsided.
The goal of this year’s coordinated release of water is to extend the high flows, not add to the peak flow, as it is in most years, said Don Anderson, a hydrologist with U.S. Fish and Wildlife, who said care is being taken not to increase the risk of flooding this weekend.
The releases from Ruedi, Homestake, Wolford, Williams Fork and Green Mountain reservoirs are designed to benefit four ancient species of fish.
The well-timed higher water will send spawning cues to Colorado pikeminnows, large powerful fish that swim upstream to spawn in the gravel beds of what’s known as “the 15-mile reach.”
Higher water will give the recent offspring of razorback suckers a chance to find refuge in calm side channels.
Higher, faster water will scour fine silt from gravel beds, flush away dry-year vegetation growth and help the river absorb nutrients from wet floodplains.
And the high water will also benefit populations of humpback chubb downstream of Grand Junction — at Blackrocks, in Westwater canyon and near Moab — and may also help the struggling bonytail chubb.
As part of this year’s effort, the outflow from Ruedi Reservoir into the lower Fryingpan
Reservoir will rise Sunday by 100 cfs, and over three days, the releases will climb from 354 cfs to 630 cfs or above, before stepping back down Wednesday.
The flow from Rocky Fork Creek, which runs into the Fryingpan below Ruedi Dam, was adding 75 cfs to the river Friday, which means the ’Pan could be 700 cfs or above by Tuesday or Wednesday.
Tim Miller, a hydrologist at the Bureau of Reclamation, said a flow of about 700 cfs is consistent with most of the other 10 years since 1997 that Ruedi has participated in what is called the Coordinated Reservoir Operations, or CROS, program.
Miller’s operational goals with this year’s CROS program include keeping outflow from the reservoir below inflow, so he can fill the 102,000 acre-foot reservoir in early July, while keeping flows in the lower Fryingpan below 850 cfs.
Releases from Homestake Reservoir, which is on Homestake Creek in the Eagle River basin and is managed by Aurora and Colorado Springs, are going to climb in a similar timeframe as Ruedi’s, moving from 6 cfs to 100 cfs Monday and then stepping back down to 6 cfs by week’s end, according to a summary of the expected releases from the Colorado River Basin Forecast Center.
Releases from Green Mountain Reservoir, which is on the Blue River north of Silverthorne and managed by Reclamation, are slated to rise from 800 cfs to 1,400 cfs and then drop back down.
Releases from Williams Fork Reservoir, which is on a tributary of the Colorado east of
Kremmling and managed by Denver Water, will increase from 350 cfs to 650 cfs and then drop.
And Wolford Reservoir, on Muddy Creek north of Kremmling and managed by the Colorado River District, is currently spilling about 400 cfs of water due to high inflows. The River District regularly participates in the CROS program, but this year is spilling water in any event and not releasing water just for the CROS program as it often does.
During a series of conference calls over the past several weeks, reservoir managers have
described this year’s snowpack as “bashful” and “tentative” and “well-behaved” due to colder temperatures in May and June. And while the snow is still deep in the Colorado River’s headwaters, more cool weather is in the forecast.
And every water manager sounds glad there is at least water this year to run after last year’s deep drought, and most now expect their reservoirs to fill, which gives them flexibility this week to release water for the fish and for the river.
This year’s high flow — 21,000 cfs, forecast for Saturday — is the opposite of last year, when the Colorado peaked, as measured at the Cameo gage, on May 19 at about 6,800 cfs.
From the Carbondale and Rural Fire Protection District via The Aspen Daily News:
Two community meetings in June will address the threat of runoff, flooding and debris flow in the area.
A news release from the Carbondale and Rural Fire Protection District states that the first gathering will be held from 6-7 p.m. June 5 at the Redstone Fire Station. It will focus on the threat of flooding from the Crystal River Valley due to heightened snowpack and the delay in runoff due to lower than normal spring temperatures.
The public will get the opportunity to ask questions about how to prepare for flooding and other incidents. Representatives of the fire district will be present, as will emergency officials from Pitkin County government and the Colorado Department of Transportation.
The release also says that a similar meeting is scheduled for June 10 starting at 6 p.m. at the Eagle County annex building, 20 Eagle County Drive in El Jebel. Officials plan to discuss the threat of runoff and debris flow in areas that were scarred by last summer’s Lake Christine Fire.
“Emergency officials are advising residents who live in and around the Lake Christine burn scar area to be aware of the high risk for flash flooding and mud and debris flows that could occur after heavy rainfall,” the release states. “The precipitation, coupled with the burn scar, warmer temperatures and above-average snowpack, is expected to produce a faster and heavier runoff period.”
Wildfires result in a loss of vegetation and leave the ground charred and unable to absorb water, according to the release, creating conditions for flooding.
“Even areas that are not traditionally flood-prone are at risk of flooding for up to several years after a wildfire. The prospect for a wetter-than-normal spring has emergency officials from Eagle, Pitkin and Garfield counties planning for mud and debris flows,” the release adds.
Following higher-than-normal snowfall, officials prepare for the likelihood of flooding that can occur in and around local creeks, rivers and reservoirs, the release says. The weather forecast through May indicates a higher chance of above-normal precipitation over western Colorado, including the central mountains, Aldis Strautins, a service hydrologist for the National Weather Service, said in a prepared statement.
“With the anticipated high water runoff, potential flooding and increased risk of debris flows, it is important that all of our public safety and support agencies work together to plan and coordinate our response before there is an emergent need. We also want to make sure our communities are aware of the above-average risk for these events and prepare for them this year,” Eagle County Sheriff James van Beek said.
Midvalley residents, regardless of whether they live in Eagle or Pitkin County, are encouraged to register for Pitkin alerts. When the weather service issues a flash flood warning in the Lake Christine burn areas, the alert system will send out notifications to users who are registered via pitkinalert.org. Registered users of EC Alert also will receive notifications.
Those who only want to receive information about the threat of flash floods, mudslides and debris flows from the Lake Christine burn scar are invited to text LCFLOOD to 888777, the release says.
“People should remember to use caution around fast-moving streams and rivers, especially in a high runoff year,” the release says. “Those who live near the Lake Christine burn scar should be prepared to quickly move to higher ground or evacuate if necessary.”
Those who keep an eye on the lower Fryingpan River, below Ruedi Reservoir, may have noticed that the river’s flow increased this week in three distinct steps.
On Monday, the river was flowing steadily at just about 200 cubic feet per second.
On Tuesday, it stepped up to 250 cfs, and on Thursday, it took another 50 cfs jump, to 300 cfs.
And on Friday, the river jumped another 25 cfs, heading into the weekend flowing at about 325 cfs. (See USGS gage).
The increases in flow were directed by Tim Miller, a U.S. Bureau of Reclamation hydrologist who manages water levels in Ruedi and also manages water releases from the reservoir, which is about 14 miles above Basalt.
The water from the reservoir was being released through the dam’s outlet structures, as well as through the hydropower plant at the base the dam, into an area that’s popular with anglers, and large fish, and nicknamed the “Toilet Bowl,” due to its swirling waters.
Miller’s goal is to fill the reservoir by July 4, while avoiding overfilling the reservoir, which would cause water to flow over the dam’s spillway, which does not have a flow-controlling gate, as some spillways do.
Miller is now balancing some factors beyond his control: the deep snowpack above Ruedi, lingering cold temperatures and varying flow levels in the transmountain diversions tunnels in the upper Fryingpan Basin.
On Friday, Ruedi was 64.6 percent full and holding 66,116 acre-feet of water, according to Reclamation. When full, the reservoir holds 102,373 acre-feet.
But, given the deep snowpack above Ruedi, Miller said “it’s very possible” the reservoir could spill, something that, to his knowledge, has only happened a few times since the reservoir and dam were completed in 1968.
The Ivanhoe snow-telemetry, or SnoTel, site above Ruedi, in the Ivanhoe Creek subbasin, is at 10,400 feet. The site shows there was still 54 inches of snow at that elevation Friday. That’s up from 42 inches a week ago but still below the March 14 peak of 90 inches.
“It just really depends on the weather,” Miller said of future releases into and out of Ruedi.
Peak runoff in the upper Colorado River basin within Colorado is now expected to arrive late, between June 15 and June 25, as more cool weather is in the forecast.
Not for flood control
Victor Lee, also a hydrologist with the Bureau of Reclamation, made a presentation on Ruedi and Green Mountain reservoirs Monday at the Colorado River Basin roundtable in Glenwood Springs.
He said he expected, because of the snowpack, to see above-average releases out of Ruedi as the reservoir fills and to see above-average diversions through the Boustead Tunnel, which sends water collected by the Fryingpan Arkansas Project diversion system under the Continental Divide to Turquoise Lake, near Leadville.
Since 1972, the Fry-Ark Project has diverted an average of 54,000 acre-feet a year through the Boustead Tunnel, but it’s expected to divert 84,000 acre-feet this year, according to Lee.
On Friday, the tunnel was sending east a relatively modest 38 cfs of water, but it had been sending about 300 cfs on May 17.
Lee also sounded a cautionary note about the rare prospect of Ruedi filling, spilling and sending at least 600 cfs of water down the lower Fryingpan.
“I have to stress that Ruedi is not a flood-control project, and if we get filled, there are no gates on the spillway to stop water from going,” Lee said. “And so, if we’re full, and we fill before peak runoff, there is always that chance that we would have excess flows beyond 600 cfs.”
Aspen Journalism covers rivers and water in collaboration with The Aspen Times. The Times published a version of this story on Saturday, May 25, 2019.
Ruedi Reservoir on Friday was just under 63 percent full as it continues to recover from the recent drought, but the wet, cool spring — more snow and rain is possible today — means there is plenty of snow remaining in the upper Fryingpan River Valley.
Gauges at and near the reservoir show winter is loosening its grip, albeit slowly. The Ivanhoe Snotel site, which sits at 10,400 feet, had a snowpack Friday that is 185 percent of normal for the day, while the Kiln site (9,600 feet) stood at 161 percent of average.
That simply means more snow is locked in at high elevations than normal for this time of the year, said John Currier, chief engineer with the Colorado River District.
“This year the snow is melting out a little later higher up,” he said. “I do expect water to be fairly high for the reservoir.”
Currier predicted Bureau of Reclamation officials, who control releases from Ruedi, to keep flows in the Fryingpan at around 300 cubic feet per second (CFS) for most of the summer. That level, which will increase drastically as snowmelt increases and fills the tub, is preferable for “fisherman wade-ability reasons,” he said. “They are typically going to have to bypass [that CFS rate] because there’s much, much more water during runoff.”
Ruedi being roughly three-quarters full in mid-May is somewhat below normal, said Mark Fuller, who recently retired after nearly four decades as director of the Ruedi Water and Power Authority. That’s a sign of both a stubborn snowpack and the reclamation bureau “trying to leave plenty of room for late runoff in anticipation of a flood out of the upper Fryingpan when it gets warm,” he said…
Releases from Ruedi may make fishing the gold-medal waters below the reservoir a bit more difficult when they occur, but greatly aid the river environment in the long term, said Scott Montrose, a guide with Frying Pan Anglers.
Here’s the release from the Southeastern Colorado Water Conservancy District (Chris Woodka):
Agriculture received the lion’s share of water from the Fryingpan-Arkansas Project this year, when an abundant water supply is expected to boost Arkansas River flows as well as imported water.
Allocations totaling 63,000 acre-feet were made by the Southeastern Colorado Water Conservancy District board on Thursday (May 16), with 48,668 acre-feet going to agriculture, and 14,332 going to cities. The district is the agency responsible for management of the Fry-Ark Project, which is operated by the U.S. Bureau of Reclamation.
“This is a remarkable outcome for the Arkansas River basin, given the dry conditions we faced last year,” said Garrett Markus, water resources engineer for the district. “The conditions look favorable during the next three months, when rainfall should add to the abundant snowpack already in the mountains.”
Water users in nine counties benefit from the supplemental water provided by the Fry-Ark Project, ranging from large cities in Pueblo and El Paso counties to irrigation companies in the Lower Arkansas Valley. Fry-Ark Project water accounts for about 10 percent of flows in the Arkansas River annually.
While cities are entitled to more than 54 percent of project water, their accounts in Pueblo Reservoir are relatively full, freeing up additional water for agriculture. Municipal allocations include:
Fountain Valley Authority, 7,353 acre-feet;
Pueblo Water, 2,000 acre-feet;
Cities west of Pueblo, 2,312 acre-feet;
Cities east of Pueblo, 2,667 acre-feet.
In the event of changing conditions – a reduction of precipitation or rapid melt-off of snow – the District initially will release only 28,256 acre-feet of water to irrigation companies until final imports are certain, with the remainder delivered as soon as the expected total is reached. Municipal allocations would not be affected by a shortfall, because they are all below allocation limits.
Another 17,338 acre-feet of irrigation return flows were allocation, and 10,016 acre-feet will be initially released.
Reclamation estimates the project will yield 84,000 acre-feet this year, but deductions from that total are made for evaporation, transit loss and obligations to other water users reduce the amount of water available to allocate.
The Fry-Ark Project imports an average of about 56,000 acre-feet through its collection system in the Fryingpan River and Hunter Creek watersheds above Basalt. Water comes through the Boustead Tunnel into Turquoise Lake, through the Mount Elbert Power Plant at Twin Lakes and into terminal storage at Pueblo Reservoir.
Three-month projections from the National Oceanic and Atmospheric Administration predict cooler and wetter than average conditions for eastern Colorado.

The tunnel moves water from tributaries of the Roaring Fork and Fryingpan rivers under the Continental Divide for use by Front Range cities, and Pitkin County officials have concerns that more water will someday be sent through it.

Releases from Ruedi Dam to the Fryingpan River are scheduled to decrease from 350 to 300 cubic feet per second on Monday, September 24 at 8 a.m.
This release rate maintains “fish water” deliveries to the 15-mile Reach for endangered fish species. Routine updates to follow. Feel free to contact me with any questions at firstname.lastname@example.org or by phone at 970-962-4326.
FromAspen Public Radio (Elizabeth Stewart-Severy):
While most local rivers are flowing at levels far below average, the Fryingpan is the exception. Releases from Ruedi Reservoir are supplementing low flows downstream, in the Colorado River.
The Bureau of Reclamation controls the amount of water that flows out of Ruedi dam, and announced this week that flows in the Fryingpan will increase to 400 cubic feet per second (cfs), more than double the average.
The increases will mean more water delivered to irrigators with senior water rights in the Grand Valley. It will also provide water to four endangered fish in an area known as the 15-Mile Reach near Grand Junction.
Flows in the Fryingpan River are expected to remain at 400 cfs through the end of September.
The release from Ruedi will be increased Tuesday morning by approximately 45 cfs. After this change, the flow at the Fryingpan River gage below Ruedi Reservoir will increase from 178 cfs to approximately 223 cfs.
This flow increase was requested by the USFWS to support fish recovery efforts in the 15-Mile reach of the Colorado River.
This release rate will continue until further notice.
FromThe Grand Junction Daily Sentinel (Dennis Webb):
The Colorado River District has agreed to boost water levels to help fish in the Roaring Fork River watershed while also conserving water for use by local irrigators later in the season and improving the chances for boosting flows this fall for endangered fish.
The action also could help protect water quality in the case of anticipated ash in waterways due to expected flooding and debris flows resulting from the Lake Christine Fire near Basalt.
The river district is releasing water from Ruedi Reservoir above Basalt to boost flows in the Fryingpan River and Roaring Fork River to help reduce water temperatures to benefit trout. Low flows and warm temperatures in western Colorado have led to Colorado Parks and Wildlife urging anglers to avoid fishing later in the day on numerous western Colorado waterways due to the stress trout currently are facing.
The U.S. Bureau of Reclamation approved the river district releases last week. They are expected to range between 50 and 100 cubic feet per second.
River district spokesman Zane Kessler said the water to be released is owned and managed by the river district’s enterprise…
The water technically is being delivered downstream for Grand Valley irrigation needs but is creating environmental benefits on its way there. The water otherwise would have been delivered from Green Mountain Reservoir south of Kremmling.
Kessler said the Ruedi releases will allow for conserving a part of what’s called the historic users pool at Green Mountain Reservoir for use later in the season, which would benefit Grand Valley irrigators. The releases also increase the chances that, despite it being a dry year, that pool can be declared to have a surplus. That surplus could then be delivered in September and October to what’s known as the 15-Mile Reach, a stretch of the Colorado River in the Grand Valley where the flows would benefit endangered fish.
“This has never been done before,” Kessler said of the flow agreement. “But we’ve rarely seen river levels like this before either.”
The potential for easing the impacts of ash flow also could be felt in the Grand Valley. There is concern that ash flows could force the Clifton Water District to suspend use of Colorado River water. Area water providers have an agreement to help each other in meeting short-term water needs should that kind of emergency situation arise, but doing so this year would further deplete drought-stressed supplies.
Kessler said retaining some Green Mountain Reservoir water for release later in the year also could benefit recreational uses of the Upper Colorado River.
Meanwhile, the river district is taking another step aimed at helping ensure that benefiting fish in the Roaring Fork Valley doesn’t harm fish on the Colorado River upstream of the Roaring Fork confluence. The district is currently delivering what Kessler called “fish water” from Wolford Reservoir north of Kremmling into the upper Colorado River because it is having to lower the reservoir’s water level in preparation for doing some work on the dam there.
The Colorado River District is working with state and federal water managers to increase flows in the Fryingpan River by as much as 100 cubic feet per second (cfs), helping trout in the watershed survive warm temperatures while supplying water for downstream irrigation needs in the Grand Valley.
Anticipated releases are expected to range between 50 cfs and 100 cfs and will be coordinated between the River District, the U.S. Bureau of Reclamation and the U.S. Fish and Wildlife Service to increase flows in the Fryingpan and Roaring Fork rivers downstream from Ruedi Reservoir.
“This should significantly benefit flows below Ruedi Reservoir,” said John Currier, chief engineer for the district. “We expect that the supplement flows may also help to mitigate water-quality problems anticipated from fire-related ash and debris flows stemming from the Lake Christine Fire on Basalt Mountain.”
Technically, the water will be delivered downstream for Grand Valley irrigation needs while creating environmental benefits as it flows downstream. Green Mountain Reservoir releases will be reduced by an equal amount in order to conserve storage for late-season releases, which in turn will be needed to help endangered fish near Grand Junction.
The coordinated approach was given final approval by the Bureau of Reclamation on Monday. In order to boost Fryingpan levels while the plan awaited approval, the U.S. Fish and Wildlife Service implemented a 50 cfs release from its dedicated endangered fish pool in Ruedi on Friday. Those flows were supplemented by 30 additional cfs Monday, bringing the flow in the Fryingpan to 200 cfs.
Both Ruedi and Green Mountain reservoirs contribute water to the Upper Colorado River Endangered Fish Recovery Program. In this case, the changed water release plan will benefit trout below Ruedi while endangered fish still receive water from upstream Colorado River reservoirs.
Increased flows of cold water out of Ruedi should also help to alleviate some stress on trout fisheries in the watershed brought on by higher-than-normal water temperatures. Colorado Parks and Wildlife announced voluntary fishing closures earlier this month on sections of the Colorado and Roaring Fork rivers.
Here’s the release from the Bureau of Reclamation (Peter Soeth):
The Bureau of Reclamation has scheduled the annual public meeting to discuss the Ruedi Reservoir Water Operations for the 2018 water year.
The meeting will be held on August 9, 2018, from 6:30-8:00 p.m. at the following location:
Roaring Fork Conservancy River Center
22800 Two Rivers Road
Basalt, CO 81621
The meeting will provide an overview of Ruedi Reservoir’s 2018 projected operations for late summer and early fall, which are key tourist seasons in Basalt. Also, representatives of the Colorado Water Conservation Board and the U.S. Fish and Wildlife Service will give a presentation on the upcoming implementation of the Ute Water Conservancy District lease of Ruedi Reservoir water to the Board for instream flow use in the 15-Mile Reach of the Colorado River. The meeting will include a public question and answer session.

FromAspen Journalism (Heather Sackett) via The Glenwood Springs Post Independent:
The Colorado Water Conservation Board on Wednesday approved two leases of water from Ruedi Reservoir designed to help different types of fish populations in the Colorado and Fryingpan rivers.
For the fourth year in a row the state agency will lease water from the Ute Water Conservancy District to bolster flows in what’s known as the “15-mile reach” of the Colorado River between the Palisade area and the confluence of the Gunnison River in Grand Junction. That stretch of the river is critical habitat for native endangered fish species, including the humpback chub.
This year’s renewed lease agreement will allow the CWCB, which was meeting this week in Glenwood Springs, to release from Ruedi Reservoir 6,000 acre-feet of water held for the Ute Water Conservancy District by the Bureau of Reclamation, which operates the reservoir.
At $7.20 per acre-foot, it will cost $43,200 and come out of the CWCB’s species conservation trust fund. The water releases will take place during September and October, according to Linda Bassi, chief of the CWCB’s stream and lake protection department.
“It’s really important for us to be providing water to the 15-mile reach,” Bassi told the directors of the CWCB. “Every drop counts.”
The directors of the CWCB met Wednesday and Thursday as part of their practice of meeting in different parts of the state. On Tuesday, the agency’s board of directors took a tour of Ruedi Reservoir and attended an informational event at the Aspen Yacht Club on the reservoir hosted by the Southeastern Water Conservancy District.
On Wednesday, Bassi described for the directors some of the drastic impacts that low flows can have on fish, including making fish more vulnerable to avian predators, leaving them stranded in small pools or even causing them to get sunburned.
Large diversions on the Colorado River above Palisade that send irrigation water to the Grand Valley, along with other diversions upstream on the river system, can cause the 15-mile reach flows to plummet to detrimental levels.
To help offset the diversions, officials with the Upper Colorado River Endangered Fish Recovery Program have set a low-flow target of 810 cubic feet per second this year. The leased water aims to help meet that target.
Since the beginning of July, the flows in the 15-mile reach have fluctuated between about 400 to 500 cfs, well below the target of 810 cfs.
A condition of the lease between Ute Water and the CWCB is that releases from Ruedi will not exceed 300 cfs and will not cause flows in the lower Fryingpan River below the reservoir to exceed 350 cfs, as flows at that level can make it difficult for anglers to wade in the popular fly-fishing river.
The lower Fryingpan on Wednesday flowed at 150 cfs.
WINTER FLOWS IN FRYINGPAN
The CWCB board also approved a lease from the Colorado River Water Conservancy District to increase winter flows on the lower Fryingpan. The proposal was first introduced in May.
The lease will boost the minimum instream flow below Ruedi Reservoir between Jan. 1 and March 31 from 39 cfs to 70 cfs in an effort to prevent the formation of anchor ice.
Low streamflows, combined with frigid temperatures, can lead to ice forming on the bottom of the river. This has a negative effect on aquatic insects, which are food for the brown, rainbow and cutthroat trout that call the lower Fryingpan home.
Under the agreement, the CWCB will pay $65.25 per acre-foot to lease up to 3,500 acre-feet from the River District, for a total cost of $228,775.
The district owns a total of 11,413.5 acre-feet of water in Ruedi, with 7,500 acre-feet of that available for leasing. Of the total the district owns, 5,412.5 acre-feet is to support flows for the endangered fish recovery program.
The proposal to maintain a healthy food source for the “gold medal” fishery’s population of trout was a collaboration between the River District and the Roaring Fork Conservancy, which is based in Basalt.
“We are excited to see [the lease] approved and to partner with the CWCB and the River District,” said Heather Tattersall Lewin, watershed action director for the Conservancy. “It’s really the first lease of its kind.”
Although the CWCB board unanimously approved the Ruedi water leases, two board members raised questions about the differing cost per acre-foot for the two projects.
At more than $65 per acre-foot, the River District water costs roughly nine times more than the water leased from Ute Water.
Over the previous three years, the CWCB has spent a total of $194,400 on the Ute Water lease for a total 27,000 acre-feet.
Board member Patricia Wells, who represents the city and county of Denver, said she was trying to reconcile the dramatic difference in price.
Jim Yahn, the current CWCB chair, who represents the South Platte River basin, asked whether CWCB staff had negotiated the cost of the lease with the River District. They did not, Bassi said.
“It struck me, the price difference,” Yahn said.
River District Chief Engineer John Currier explained that earlier this year, in response to the leasing proposal, his organization created a third use-category in addition to its existing categories of agriculture and municipal/industrial: in-channel use.
The River District then decided to market the water at the same price as they do for agriculture use.
“The River District runs a water marketing enterprise,” Currier said. “It’s my job to make sure that enterprise runs in the black.”
Ute Water External Affairs Manager Joe Burtard said the water provider does not try to generate revenue with its leases; instead it simply wants to cover its costs associated with operation and maintenance of the reservoir.
The cost of the River District water didn’t seem to bother board member Russ George, who represents the Colorado River basin on the CWCB board. He said the instream flow leases demonstrate the importance of Ruedi as a storage unit.
“I’m delighted the River District bought the water and we have it for use today,” he said.

FromAspen Journalism (Heather Sackett) via The Glenwood Springs Post Independent:
Very low flows in the upper Colorado River system are now expected to trigger calls from senior water rights tied to the Shoshone hydropower plant and irrigators in the Grand Valley. And, starting Friday, more water is to be released from Ruedi Reservoir into the lower Fryingpan River to bolster downstream flows.
The Shoshone plant has two water rights, a very senior 1902 right and a less-senior right for 158 cubic feet per second with a 1929 priority date. A call for the 1929 Shoshone right is expected to take effect on Thursday, meaning those upstream from the Shoshone hydro power plant in Glenwood Canyon who hold junior rights must stop diverting.
On July 1, another, larger call is expected to happen downstream on the Colorado — the Cameo call. The Cameo call is made up of the water rights of agriculture diverters near Palisade, including the Grand Valley Water Users Association and the Orchard Mesa Irrigation District.
The Cameo call, which is the second-most senior water right on the Colorado River, calls about 2,200 cfs down through the river system, but the diversion structures tied to the call also have the potential to nearly dry up the Colorado River in a 15-mile reach between the Palisade area and the confluence of the Gunnison River in Grand Junction. This 15-mile reach is critical habitat for endangered fish, including the Humpback Chub.
To help offset the effects of the Cameo call and other diversions on the river system, officials with the Upper Colorado River Endangered Fish Recovery Program have set a low-flow target of 810 cfs this year.
And, after meeting with other regional water managers on Wednesday, officials with the U.S. Fish and Wildlife Service plan to release on Friday 50 cfs of water that has been earmarked specifically for endangered fish from Ruedi Reservoir. Another 100 cfs will be added to the bolstered flows on Monday, bringing releases to about 260 cfs in the river below Ruedi Reservoir.
While a Cameo call is not unusual and often happens in late summer, this is the earliest it has ever taken effect, according to Don Meyer, Senior Water Resources Engineer with the Colorado River District. The previous record was July 14.
“It’s a brutal year,” Meyer said. “I think it’s going to be a dire situation for everybody, but especially the fish down there.”
This year is also the second earliest that “fish water” has been released from Ruedi Reservoir since the endangered fish program was established in 1988. During the most recent drought years, 2002 and 2012, fish water was released on June 24 and July 3, respectively.
Federal officials this year expect to be able to release 16,412.5 acre-feet of fish water from Ruedi Reservoir this year, including from a 5,000 acre-foot pool, a 5,412 acre-foot-pool and 6,000 acre-feet of water owned by Ute Water Conservancy District in the reservoir, which is to be leased for the endangered fish program.
In all, the fish program has a total of 28,000 acre-feet of water it can use from various reservoirs in the upper Colorado River system, including Ruedi, Granby and Wolford reservoirs.
The Cameo call will also put more water into the Roaring Fork River by “calling out” the transmountain diversion through the Twin Lakes tunnel under Independence Pass. The Twin Lakes Reservoir and Canal Company can move 625 cfs of water out of the Roaring Fork Basin to the Arkansas Basin, where it is used for East Slope municipal and irrigation purposes.
The tunnel is currently diverting around 50 cfs, but that will come to a halt when the Cameo call goes into effect.
“In one respect it’s a windfall for the Roaring Fork,” said Kevin Lusk, president of Twin Lakes Reservoir and Canal Company. “It’s not good for our customers, but that’s the law. It’s just part of owning a water right on a river in Colorado. This is one of those dry years so we are not surprised to see the Cameo call come on.”

As a way to settle a 2009 state water court case led by Pitkin County and the Colorado River District, the Front Range city of Aurora has agreed to let as much as 1,000 acre-feet of water run down the upper Roaring Fork River each year instead of diverting the water under Independence Pass.
The pending settlement could mean that about 10 to 30 cubic feet per second of additional water could flow down the river through Aspen in summer and fall.
It’s an amount of water that Pitkin County Attorney John Ely said would be “visibly noticeable” and would help bolster flows in the often water-short stretch of the Roaring Fork between Difficult and Maroon creeks.
“It’s exciting,” Ely said. “It’s not very often you get to put water into the upper Roaring Fork. These opportunities are pretty limited, and I’m not sure if we’ll ever see another one.”
A June 13 memo from Ely on the agreement states that “the Pitkin County Healthy Rivers and Streams Board has long recognized this reach of the Roaring Fork as one of the most stressed reaches of the Roaring Fork” and that “the Roaring Fork Conservancy’s State of the Watershed report identifies the upper Roaring Fork just above Aspen and heading into town as being severely degraded.”
The Pitkin Board of County Commissioners is expected to approve the settlement in the form of an intergovernmental agreement with Aurora on Wednesday.
Aurora’s city council also is expected to approve the agreement, as is the Colorado River District board of directors at its July meeting. A Water Court judge has set a July 20 deadline for the parties to file the settlement.
Officials with Pitkin County and the Colorado River District see the deal with Aurora as a victory, especially as some estimates, according to Ely, place the value of water in Aurora at $50,000 an acre-foot, which makes the 1,000 acre-feet of water potentially worth $50 million.
The settlement is also of high value to officials at the Colorado River District, who led the efforts of the West Slope entities in the case.
“I think it’s a big deal,” said Peter Fleming, the general counsel for the Colorado River District, which represents 15 counties on the Western Slope. “I think it’s going to be a good deal for Pitkin County, the Roaring Fork River, and the West Slope as a whole. And frankly, I think it’s a pretty good deal for Aurora, as well.”
But Tom Simpson, a water resource supervisor with Aurora, said it’s a “bittersweet” deal for the growing Front Range city.
“We’ve worked hard on this agreement over the last year,” Simpson said. “It is bittersweet, but we are happy that we are finally there.”
The deal lets Aurora retain its current use of 2,416 acre-feet of water it diverts on average each year from the top of the Fryingpan River Basin, but Aurora also is giving up 1,000 acre-feet of water it now diverts from the top of the Roaring Fork River Basin.
Aurora also is agreeing to abide by operating protocols and future potential use of the senior water rights on the Colorado River now tied to the Shoshone hydropower plant in Glenwood Canyon. That agreement could limit the amount of additional water Aurora can divert in the future from the Colorado River Basin.
The provisions of the agreement relating to the Shoshone water right also include an acknowledgement that the senior water right might someday be changed to include an instream flow right rather than the water being diverted out of the river and sent to the hydropower plant.
“Aurora will not oppose an agreement between a West Slope entity or entities, the Colorado Water Conservation Board, and any other entity entered for the purpose of adding instream flow as an additional use of the senior hydropower right,” the agreement states.
Simpson agreed the overall deal represented a “haircut” for Aurora’s water rights in the Colorado River Basin.
“Yes, we’re going to get the 2,416 acre-feet out of Busk, but we’re going to make these other deliveries on the Roaring Fork, and we might lose just a little bit of water on the Shoshone protocol,” he said. “It’s a haircut, absolutely.”
On the other hand, Simpson said “while this agreement is not perfect, we feel like it is a good agreement, and preserves some of our Busk-Ivanhoe water and lets us all move forward.”
Started in 2009
In December 2009, Aurora filed a water rights application in Division 2 Water Court in Pueblo to change the use of its water rights in the Busk-Ivanhoe transmountain diversion system in the Fryingpan River headwaters.
The system, built in the 1920s, gathers water from Ivanhoe, Pan, Lyle, and Hidden Lake creeks and diverts the water through the Ivanhoe Tunnel to Turquoise Reservoir near Leadville before it is sent to East Slope cities. The system was built to deliver water to irrigators in the lower Arkansas River basin.
The water rights to the system carry appropriation dates from 1921 to 1927, which makes them junior to the senior water rights on the Colorado River near Grand Junction known as the “Cameo call.”
The Pueblo Board of Water Works bought half of the Busk-Ivanhoe system in 1972, and Aurora gradually secured its half-ownership in the system between 1986 and 2001.
In its 2009 application, Aurora told the water court it wanted to change the use of its water in the Busk-Ivanhoe system from irrigation to municipal use.
However, it also conceded it had already been using the Busk-Ivanhoe water for municipal purposes in Aurora, even though its water-right decree limited the use of the water to irrigation in the lower Arkansas River valley. It also came to light that Aurora was first storing the water in Turquoise Reservoir without an explicit decreed right to do so.
That caught the attention of Pitkin County, the Colorado River District, a host of other Western Slope water interests, and the state engineer’s office, which administers water rights.
As Ely put it in a June 13 memo to the Pitkin County commissioners, “In 1987, Aurora began using Busk-Ivanhoe water for undecreed municipal and residential purposes in an undecreed area, the South Platte Valley, after storing the water in an undecreed manner in Aurora system reservoirs.”
Aurora’s stance was that since the water had been diverted under the Continental Divide, it didn’t matter how it used or stored the water, as it should make no difference to the West Slope. But an array of West Slope entities, including the Colorado River District, disagreed with Aurora’s position.
In July 2013 the Western Slope entities and the state took Aurora to a five-day trial in Div. 2 Water Court in Pueblo, arguing that Aurora should not get credit for its 22 years of undecreed water use and storage.
“It was always an issue of fact at trial as to how much water was in play because it depends on how you calculate the yield of the project,” Ely said.
In 2014, thought, the district court judge in Division 2 ruled in Aurora’s favor, and the West Slope interests then appealed to the state Supreme Court.
The appeal process prompted a host of entities on both sides of the Continental Divide to come forward and argue aspects of the case before the court. It also prompted a scolding of Aurora by former Supreme Court Justice Greg Hobbs over the use of undecreed water rights.
In 2016, the Colorado Supreme Court reversed the lower court’s decision, ruled in favor of the Western Slope, and remanded Aurora’s original change application back to the lower court.
“The Supreme Court wrote that notwithstanding the fact that the change application and original decree concerned developed transmountain water, water used for undecreed purposes cannot be included in a calculation for historic consumptive use and is therefore excluded from water available for change of use,” Ely wrote in his June 13 memo.
So, rather than going back to Water Court and continuing to fight over the potential size of the Busk-Ivanhoe rights, which the West Slope now saw as being between zero and well-less than 2,416 acre-feet, Aurora began negotiating in January 2017 with the Western Slope entities still in the case, which included Pitkin County, Eagle County, the Colorado River District, the Grand Valley Water Users Association, the Basalt Water Conservancy District, Eagle County, Orchard Mesa Irrigation District, and Ute Water Conservancy District.
Today, each of those entities is also a party to the intergovernmental agreement expected to be submitted to the water court in July, along with a proposed decree for Aurora’s Busk-Ivanhoe rights.
Ely said Pitkin County didn’t start out in the case with an eye on securing 1,000 acre-feet for the Roaring Fork, but did have a local interest in the operation of the Busk-Ivanhoe project.
“We weren’t doing it to obtain an end result, we were doing it because the [Busk-Ivanhoe] project is in our backyard and we felt it was the right thing to do,” Ely said. “And all the other dialogue developed after the trial and the Supreme Court decision.”
At the time of the 2016 Colorado Supreme Court decision, Pitkin County had spent $353,000 in legal and other fees in the case, using money brought in by a tax to fund the county’s Healthy River and Streams program, which includes litigation in water court.
Since then, Ely said the county had spent an additional $27,300 for hydrology and engineering work, but had not spent more on additional outside legal help, as he and Assistant County Attorney Laura Makar handled the settlement negotiations for the county.
Pan, or Fork?
For Pitkin County and other Western Slope entities, it made more sense to negotiate with Aurora for some of the water it owns in the Independence Pass-Twin Lakes system rather than the Busk-Ivanhoe system, as any water bypassed by the Busk-Ivanhoe system would be scooped up by the Fry-Ark Project, which sits below the Busk-Ivanhoe system in the upper Fryingpan valley and also diverts water to the East Slope.
Aurora owns 5 percent of the shares in the Twin Lakes Reservoir and Canal Co., which operates the Independence Pass Transmountain Diversion System. Its share of the water diverted each year from the top of the Roaring Fork equals about 2,100 acre-feet a year, so the 1,000 acre-feet of water equals about half of Aurora’s water in the Twin Lakes company.
In the 10 years from 2007 through 2016, Twin Lakes Co. diverted a total of 485,762 acre-feet of water from the upper Roaring Fork River Basin through its diversion system, putting the 10-year average for that period at 48,567 acre feet. 2011 was the biggest year of diversions since 2007, with 67,463 acre-feet diverted, and 2015 was the lowest year since 2007, with 18,374 acre-feet diverted.
Colorado Springs owns 55 percent of the shares in Twin Lakes Co., Pueblo 23 percent, Pueblo West 12 percent, and Aurora 5 percent. There are also other minority shareholders, holding 5 percent of the shares, still using the water from the system for agriculture.
Twin Lakes is not a party to the intergovernmental agreement between Aurora and the West Slope entities, but it is willing to work with all involved to make the water deliveries as beneficial as possible for the Roaring Fork River.
Ely said Pitkin Country was grateful for the willingness of the Twin Lakes Co. to work with the county and the Colorado River District to release the water in a way that benefits the river, even if it means more work for the operators of the Independence Pass-Twin Lakes system.
According to Kevin Lusk, the president of the Twin Lakes Reservoir and Canal Co. and a senior engineer at Colorado Springs Utilities, the company is simply responding to the desires of a shareholder in the company, Aurora.
He also said it’s legal under a 1976 water-rights decree held by Twin Lakes to bypass water for use on the West Slope instead of diverting it under the Continental Divide.
“The decree allows for this type of operation and so really all we’re doing as a company is accommodating the request of one of our shareholders to do something that was contemplated and provided for in the decree,” Lusk said.
And as part of the agreement, representatives from Pitkin County, the Colorado River District, Aurora, and Twin Lakes will meet each year to agree on a delivery schedule for the water that describes the “desired rate, timing, amount, location and ultimate use of the water, as well as the operational needs and constraints” of the Independence Pass-Twin Lakes diversion system.
In a letter attached to the agreement laying out how Aurora and the Twin Lakes Co. plan to manage the releases, Aurora said it “would prefer the water to be delivered at times of the year and at locations that will provide the most benefit to the Roaring Fork River stream flow. Typically this will be in the second half of the summer, beginning July 15, through the fall season.”
And Pitkin County feels the same way, according to Ely.
“We would like it delivered later in the year when the flows of the river start to go down,” he said.
However, Lusk at Twin Lakes said if the West Slope entities wait too long in the season to bypass the water, it may not be there to bypass.
“I know that there is a great interest in saving a lot of this water and bypassing it at the end of the season,” Lusk said. “But it’s going to be a bit of a balancing act. You’ve got to take the water when it’s there, because if you don’t take advantage of it there won’t be any to release later.”
Lusk also said that if the West Slope really wanted to take full advantage of the water, it might consider building a reservoir above Aspen to store the water at peak runoff and then release it later in the season.
Flows on the Fork
According to a draft resolution to be voted on by the Pitkin County commissioners Wednesday, there were several factors that went into the county’s goal of acquiring 1,000 acre-feet per year of water for the upper Fork, including “the expected amount of yield for Aurora in the Busk-Ivanhoe system; existing in-basin and out-of-basin diversions from the Roaring Fork River between Independence Pass through the City of Aspen; potential future demand on the river; extent of existing conditional water rights; and the results of a stream analysis and channel measurement study.”
If the deal is approved, as soon as next year 700 acre-feet of Aurora’s water is expected to be captured briefly in the Independence Pass system, which includes dams on Lost Man Creek, the main stem of the Roaring Fork River, and on Grizzly Creek, and then released down either the Fork or Lincoln Creek toward Aspen.
Another 200 acre-feet of Aurora’s Twin Lakes water will be held in Grizzly Reservoir on Lincoln Creek, which holds 570 acre-feet of water. That water will then be released late in the year, after most transmountain diversions have stopped, to bolster late-season flows in the river.
“So it’s actually reservoir release of previously stored water, while the [700 acre-feet] is a true bypass of water that would have gone through the tunnel that day to the other side,” Lusk said. “It’s new for us. We typically don’t operate the reservoir that way. Typically we would run that reservoir quite a bit lower, just for safety-of-dam reasons. But this change in operation is going to be holding the reservoir up much fuller for a lot longer, and we just need to watch the behavior of the dam.”
Another 100 acre-feet of water could also eventually be left in the Roaring Fork each year after a complicated exchange-of-water arrangement is worked out with Aurora and other parties on the Fryingpan River, which brings the potential total water left in the Fork to 1,000 acre-feet.
There is also a drought contingency provision which will allow Aurora to bypass 100 acre-feet less than they would have under the deal if the water level in their system of reservoirs falls below 60 percent on April 1 in a given year. So in a dry year, that could bring additional flows in the Roaring Fork back to 900 acre feet.
The pending Busk-Ivanhoe settlement also includes a provision that allows the Basalt Water Conservancy District to store 50 acre-feet of water in Ivanhoe Reservoir, which holds 1,200 acre-feet of water and serves more as a forebay for the Ivanhoe Tunnel diversions than a storage reservoir.
And, in a provision to Aurora’s benefit, the West Slope entities, including Pitkin County, have agreed not to fight, at least on a wholesale basis, the permitting of two potential reservoirs that Aurora is working on, Wild Horse Reservoir in South Park and Box Creek Reservoir, which could hold between 20,000 and 60,000 acre-feet on private land on the south flank of Mt. Elbert.
“Any participation in the permitting processes by the West Slope Parties will not seek to prevent the project in its entirety and comments or requests may be raised only for the purpose of addressing water related impacts caused directly by either of the two above specified projects on the West Slope,” the draft agreement between Aurora and the West Slope says.
The concession from the West Slope is significant as Box Creek Reservoir will be able to store water from the West Slope.
The West Slope entities also agree not to oppose changes in diversion points tied to the Homestake transmountain diversion system in the Eagle River Basin, not to oppose Aurora’s efforts to repair the Ivanhoe Tunnel, which is also called the Carlton Tunnel. The tunnel was originally built as a railroad tunnel, and then used as a highway tunnel.
Finally, the parties to the deal have agreed, in what’s called a “diligence detente,” not to challenge in water court for 15 years a list of conditional water rights, held by both East Slope and West Slope entities, that are required to periodically file due-diligence applications with the state.
The list of conditional water rights includes rights held by Aurora tied to the Homestake project and rights by the Southeastern Water Conservancy District tied to the Fry-Ark Project. They also include rights held by the Colorado River District on a number of West Slope water projects, including the potential Iron Mountain Reservoir near Redcliff and the Wolcott Reservoir near Wolcott.
Notably, the agreement does not include provisions to legally shepherd the water from the Independence Pass-Twin Lakes system all the way to the confluence of Maroon Creek, so it’s possible that diverters on the river near Aspen, such as the Salvation Ditch, could pick up the water left in the river.
However, Ely said the county will seek cooperation from diverters on the river near Aspen.
“We’ve had some conversations with water users on this side of the hill, and we’ve had conversations with the Division 5 engineer’s office, and we’re hopeful that when the water is being bypassed and put in the river and there is an increase of flow, folks won’t take advantage of that and we’ll be able to get it down through Aspen,” Ely said. “And eventually, you know things will change, and we hope to have that water associated with its own water right, so we can call it further down, but that won’t be the case right away.”
An additional benefit to the deal, according to Ely, is that the management of the 1,000 acre-foot pool of water from Aurora may also lead to better management of a 3,000 acre-foot pool of water also available in the Independence Pass-Twin Lakes system.
That pool was created to mitigate the impacts to the Roaring Fork River from diversions by the Fry-Ark Project on Hunter, Midway, and No Name creeks, which drain into the Fork in central Aspen. And while Twin Lakes releases the water down the Roaring Fork, releases from the Fry-Ark Project replace the water in Twin Lakes Reservoir, where both transbasin diversion systems can send water.
For years, the water from the 3,000 acre-foot pool has been released at a rate of 3 cfs on a year-round basis and has not been timed to help bolster low-season flows. Now, given the greater cooperation over the management of the 1,000 acre-foot pool from Aurora, how the 3,000 acre-foot pool from Fry-Ark is managed may also change, to the benefit of the river.

A proposal to increase winter flows on the lower Fryingpan River could have big benefits for downstream trout populations.
The Colorado River District is proposing to the Colorado Water Conservation Board a one-year, renewable lease of some of the water it owns in Ruedi Reservoir to boost winter flows in the Fryingpan. CWCB staff presented the proposal to the board at its May meeting in Salida.
Currently, the decreed instream flow rate between Nov. 1 and April 30 in the Fryingpan below Ruedi is a minimum of 39 cubic feet per second. Often, winter flows are higher than this, but in dry years they can hover around the minimum amount.
But 39 cfs is not enough to maintain a healthy food source for the Gold Medal fishery’s population of trout. The proposal seeks to boost the minimum flow to 70 cfs.
The proposal is a collaboration between the Colorado River District and the Roaring Fork Conservancy.
Heather Tattersall Lewin, watershed action director with the conservancy, explained that low streamflows, combined with frigid temperatures, can lead to the formation of anchor ice on the bottom of the river.
This ice has a negative effect on the population of aquatic insects, known as macroinvertebrates, which are food for the brown, rainbow, and cutthroat trout that call this 14-mile stretch of river home.
“When the water and air temperatures are both really cold, the anchor ice can scour the bottom of the river,” Tattersall Lewin said. “It can scrape the macroinvertebrates in that area and they can get moved downstream. The insect population is what we are concerned about because it’s the fish food.”
Extra water in the stream will prevent anchor ice from forming. The conservancy estimates that 56 days is the maximum amount of time the leased water would be needed during the winter.
“This is a great opportunity to manage water to the benefit of environmental and recreational needs,” Tattersall Lewin said.
Under the proposal, the CWCB would lease up to 3,500 acre-feet of Ruedi Reservoir water from the river district. It would cost $65.25 per acre-foot, plus a $400 application fee, which for the total 3,500 acre-feet would cost $228,775.
The river district owns a total of 11,413.5 acre-feet of water in Ruedi, with 7,500 acre-feet of that available for leasing. Of the total the river district owns, 5,412.5 acre-feet is to support flows for the endangered fish recovery program.
Colorado River District General Manager Andy Mueller said there are two reasons his organization decided to offer up their water for lease. The first is to improve the health of the river and its trout populations. The second is related to the business arm of the district.
“We are charged with maximizing our assets and our assets are pools of water in different reservoirs,” Mueller said. “In this instance, we are leasing water to the CWCB and they are paying our district’s enterprise fund to release that water. It’s a win-win from our perspective.”
The Fryingpan River is popular with anglers because of predictable hatches that lead to fish feeding frenzies and great conditions for dry fly fishing.
Colorado Parks and Wildlife supports the increased winter flows.
In a letter of support to the CWCB, CPW instream flow program coordinator Jay Skinner wrote, “recent history has taught us that more flow during the winter months improves fish habitat, increases spawning success and fry emergence for brown trout, promotes a more robust macroinvertebrate food base for fish and most importantly, addresses issues related to anchor ice formation and accumulation.”
The CWCB will consider the proposal for approval at its July meeting. If approved, the increase in flows could begin this winter.
