The district’s new, $27 million-plus wastewater treatment facility is nearing the end of its finishing touches after a three-year construction process. A ribbon-cutting ceremony for the new plant is tentatively set for Thursday.
Financed by a mill levy approved by the SWSD’s voters in May 2016, the facility was completed in March, whereupon the old plant was retrofitted to work in tandem with the new plant. Now, both facilities are online and working as designed, according to Hamby.
Some $23.3 million in bonds were sold for the project; the additional $4 million for the retrofitting of the old wastewater plant was financed through development-fee revenue from Snowmass construction projects, the district manager said.
In a tour of the new plant last week, Hamby beamed with pride as he described the reasons for the new plant, the complicated construction process of integrating the two plants and how SWSD employees accomplished retrofitting the old plant themselves…
While the plant took three years to build, the actual work started in 2013 when SGM, the Glenwood Springs-based company of consulting engineers, began talking to SWSD about new regulations that had recently been passed in 2012 in Colorado to reduce nutrient pollution in lakes, rivers and streams.
Regulation 85 by the Colorado Department of Public Health and Environment regulates nutrient discharges such as nitrogen and phosphorus and requires wastewater treatment plants to reduce both substances in the water that they discharge.
In the beginning, SGM and SWSD considered retrofitting the existing SWSD wastewater plant that was originally constructed in 1968 after the Snowmass ski area opened and then modified since then with additional construction.
A challenge for SWSD and the design and construction companies working on the new plant was the fact that the existing wastewater plant had to remain in operation while the new one was being constructed in order for Snowmass to meet current water regulations.
Because of this, the project was built in phases over the three-year period.
“Both plants have to be run in tandem to make this work, so we first had to build this new plant and put it online,” explained Hamby.
“Once it was constructed, we took the old plant offline, retrofitting it with new equipment, but we also had to remove a lot of the equipment that was over there. Our own people did the retrofitting work so it is really extraordinary to me that the people that maintain the plant also took responsibility to build basically a new plant inside,” he 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.

Ranchers were left with a backlog of cattle earlier this year when meatpacking plants had to close or slow production due to COVID-19 outbreaks among employees and public health orders forced restaurants to shut down indoor dining.
They are now facing the compounding challenge of a drought, which is decreasing the amount of available hay and forcing more tough choices about herd management.
“We had cattle that we would generally sell in like February and March, and that market kind of fell apart right then,” said Brackett Pollard, the Holy Cross Cattlemen’s Association local president who owns a ranch in Silt.
Pollard was finally able to sell some of his cattle in mid-July.
According to data collected by the Food and Environment Reporting Network, there have been eight outbreaks in meatpacking plants in Colorado that have led to more than 500 COVID-19 cases. That includes 316 cases at a JBS facility in Greeley. The facility had to close April 15 to 24. There have been nearly 40,000 meatpacking workers infected nationwide.
COVID-19 impacts at meatpacking plants, as well as market uncertainty as demand fell off from restaurants and schools, meant that commercial feedlots — where ranchers send cows before they are slaughtered — were packed and unwilling to buy additional cattle, according to ranchers interviewed for this story and a U.S. Department of Agriculture report.
So Pollard, like many other ranchers, didn’t have any other choice but to keep his yearling cattle that would have been sold or slaughtered earlier in the year.
That meant he had to take land that he would normally use for growing hay and repurpose it to pasture these yearling cattle, which are between 1 and 2 years old. Cattle are typically slaughtered when they are between 18 and 24 months old.
The change in operations could affect him in the long run.
“We not only do have to keep them because there was nowhere to go with them, and then all of a sudden we find ourselves in the middle of a drought,” Pollard said, noting that he was running low on hay to feed his cattle. “We basically got to the point where we had to get rid of them, whatever price was being offered.”
Pollard said he sold his cattle at their current market value, but if COVID-19 hadn’t happened, he probably would have received $200 more per head.
Beef prices rose, but cattle selling prices went down
On July 22, the USDA released the Boxed Beef and Fed Cattle Price Spread Investigation Report, which investigates the nationwide surge in retail beef prices. Between late March and early April, a large number of workers at meat-processing plants got sick, which by mid-April led to facility closures and slowdowns that reduced beef production.
The weekly number of slaughters nationwide fell from more than 684,000 head at the end of March to under 439,000 at the end of April, a decrease of 36%.
“This reduced demand for cattle may have contributed to lower fed cattle prices,” according to the report’s summary of impacts related to the COVID-19 pandemic. “Feedlot placements by producers and feeders were 22% lower in April than in 2019.”
Consumers began stocking up on beef in grocery stores in March when public health orders closing restaurants to indoor dining were first introduced. Demand from restaurants fell off dramatically, and many producers struggled to quickly shift away from restaurants and toward grocery stores, according to the report.
Consumers continued stocking up in April, as news of plant closures and fears of beef shortages spread, further driving up the cost of groceries.
The weekly average choice boxed beef cutout price — which measures the value of a beef carcass based on prices paid by end users — rose from about $255 per 100 pounds at the beginning of April to more than $459 by the second week of May.
In the meantime, packers purchased fewer fed cattle and dropped cattle prices because of the meatpacking-plant closures or production slowdowns. Fed cattle prices decreased by 18% between early April and early May.
The gap between the selling price of fed cattle to packers and the retail price of boxed beef increased from $66 per 100 pounds in early April to $279 in the third week of May, a 323% increase, the largest spread since 2001, according to the report. The gap started to narrow in June, from $279 per 100 pounds in the middle of May to $119 in the beginning of June.
Working through packer issues
According to Bill Fales, a Carbondale rancher, the gap between what ranchers are getting for their cattle and what consumers are paying for beef illustrates the problem with “packer consolidation,” or fewer meatpacking firms controlling more of the marketplace.
“It really showed the problem with the kind of conventional beef system because people who had cattle ready to be slaughtered got just slammed,” Fales said. “If they could get them killed, the price they were selling for went way down, (and) the packers started paying way less and charging way more on the other side of the plant — to the consumers.”
Fales wasn’t impacted by the drop in selling prices, he said, because his cattle are part of a program called Country Natural Beef.
Country Natural Beef is an Oregon-based cooperative of nearly 100 family ranches located in 13 Western states and engaged to produce beef from vegetarian fed cattle. The co-op, which works mainly with the grocery chain Whole Foods, sets its prices in January for the fiscal year.
Fales said at the outset of the pandemic, he experienced a slowdown in the amount of cattle he could send for processing. But as Whole Foods’ shelves were emptying in April, the grocery chain began asking for more beef. The cooperative was able to shift cattle to different processors to keep up with the demand, Fales said.
Amy Daley and Nicholas Krick are partners in Daley’s family-owned ranch in New Castle that also is part of the Country Natural Beef network, and they also sell beef products through their own business, nickandamysfarm.com. Like Fales, they were able to maintain their selling prices but still were left with an excess of cattle.
“We ended up reducing the amount of head that had been scheduled to go in to be processed, which left a lot of our animals still in the feedlot or unable to be processed,” Krick said. “We’re spending more money for that feed when they should be a beef product.”
Krick said they still have a backlog of cattle but are getting back on schedule.
Dry weather challenges ranchers
Perhaps most worrying to ranchers is the drought. This summer’s windy, dry conditions have made it difficult to grow hay, which is used to feed the cattle over the winter.
The National Drought Mitigation Center’s map and data released Sept. 1 show an extreme drought in Pitkin, Eagle and Garfield counties.
For the first time since 2013, the entire state is experiencing some level of drought. About 54% of Colorado is experiencing severe drought, and more than 35% extreme drought.
When drought is considered severe, snowpack and surface water levels are low and river flow is reduced, according to the National Drought Mitigation Center. When the drought becomes extreme, which is a worse condition, wildfire risk increases, pasture conditions worsen and reservoirs are extremely low. At any stage, drought forces farmers to reduce planting and ranchers to sell cattle.
Fales was cutting hay near Catherine Store in Carbondale, a few miles from his ranch. This year’s drought didn’t allow the hay to grow as high as usual.
“I used to think that one of the advantages of ranching here is we had a really stable climate,” Fales said. “I’ve been ranching here since 1973 — I’ve never seen less hay production than this year.”
Fales, who was hoping for a better second hay cutting, said his first cutting is down 40% from what he would normally harvest. “I’m going to have to sell cows because I just don’t have enough hay and it’s too expensive to buy to feed to cattle,” Fales said.
The hay shortage will probably lead to a surge in production costs for ranchers.
“We’re going to be having to make some decisions this fall, going into reducing herd numbers or buying hay — and from where we are getting that hay,” Daley said.
When a drought occurs, Pollard said, the increase in hay prices usually leads to a decrease in production and a surge in prices paid by consumers if demand remains the same.
For ranchers, he said, spring was the cattle-raising season, so many weren’t selling cattle yet.
“Now comes October,” he said, “(and) if the market hasn’t rebounded by then, there’s a real chance it could be very difficult for young ranchers or farmers, or those who have a lot of debt.”

On a recent morning, Liza Mitchell of Pitkin County Open Space and Trails rolled out fiber mats over a soil-filled portion of a ditch in the North Star Nature Preserve, adding a final layer to a wetland plug that the natural resource planner and ecologist and her team had been working on for the three weeks prior.
The plug is the central component of the program’s fen-restoration project, which aims to enhance the wetland’s ability to provide habitat, store and filter groundwater, and sequester carbon.
While North Star is known as an idyllic paddleboarding and beach destination, 77% of the preserve is closed to public access. This includes the property west of the Roaring Fork River, where the fen sits.
The preserve’s 245 acres function primarily to protect native species and ecosystems. The first 175 acres of the preserve were bought by the Nature Conservancy in 1977. In 2001, Pitkin County Open Space and Trails and the city of Aspen jointly purchased the 70 acres below the initial property, creating the current North Star Nature Preserve, according to the 2020 North Star management plan.
“It’s for wildlife,” Mitchell said of North Star.

Critical to the nature preserve
Aligning with the goal of conservation, Open Space and Trails staff identified the North Star fen as a site for ecological restoration. Situated in the northwest corner of the property, the 14-acre fen, which is a peat-filled wetland, is populated with sedges, reeds and grasses.
The wetland is critical to the entire preserve, providing wildlife habitat, water filtration and flood mitigation. In dry months, groundwater stored in the fen percolates into the Roaring Fork River, benefiting the watershed and its thirsty users, Mitchell said.
Yet, due to human alterations to the watershed and North Star, the fen is drying out. In 1936, two tunnels, multiple canals, and the Grizzly and Lost Man reservoirs were completed as part of the Independence Pass Trans-Mountain Diversion System. The system moves water from the upper Roaring Fork River basin to the east side of the Continental Divide, satisfying the water needs of Colorado’s largest cities, according to the 2020 management plan.
This system diverts as much as 40% of the Roaring Fork’s headwaters upstream of the preserve, reducing the volume of river water that flows into the property and saturates the fen, Mitchell said.
The fen underwent further drying in the 1950s, when the preserve was a private ranch owned by James Smith. Smith dug ditches through the fen for pasture and hay cultivation, and those ditches continue to drain standing water into the Roaring Fork, according to Mitchell.
The wetland plug combats the drying by slowing the outflow of water from the fen into the Roaring Fork River. Mitchell, two staffers from Basalt-based Diggin It Riverworks and two ecological consultants began the plug construction Aug. 10. The first week, the team filled 130 feet of the main ditch with a mixture of locally sourced and imported soil. In the second and third weeks, the team added a layer of local soil, scattered native plant seeds and sealed it all with hay, mulch and matting, Mitchell said.
“It’s been a pretty quick project,” she said. “We’ve really tried to get in, get out and minimize disturbance as much as possible.”
6,700 years of carbon sequestration
The wetland plug increases saturated conditions in the fen, or the presence of standing water, enhancing the fen’s ability to provide ecological services to the preserve. For instance, saturated conditions allow fens to function as carbon sequesters by storing peat, or carbon-rich plant material.
Peat accumulates at a rate of 8 inches per 1,000 years, according to David Cooper, wetland ecologist and professor at Colorado State University. With 53 inches of peat soil, the North Star fen is estimated to be 6,700 years old, according to a Pitkin County news release.
“Peatlands make up about 5% of the land surface of the world,” Cooper said, “but almost 45% to 50% of all the soil carbon on Earth is in peatlands.” When fens dry up, the carbon stored as peat is released as carbon dioxide, contributing to global warming, he said.
Saturated conditions also support wildlife. Standing water creates the ideal habitat for native plants, such as beaked and blister sedge, as well as native amphibians and waterfowl. Saturated conditions suffocate canary grass, an invasive species that spread increasingly through the fen as it dries up, Mitchell said.
Wet by standing water, fens filter groundwater. The peat body removes excess nitrogen as well as heavy metals that would otherwise accumulate in watershed fish populations, Cooper said.
A positive for North Star neighbors
Mitchell anticipated finishing the construction phase of the restoration project this past week. She plans to place wattles, or cylinders of hay, across the wetland plug to prevent soil and seed erosion. She also will add hay bales and cylinders to the fen’s two smaller ditches to retain water and provide a surface for native plants.
After this construction phase, a hydrologist and botanist hired by Open Space and Trails will monitor the fen for three years. The consultants will conduct studies and submit reports to the U.S. Army Corps of Engineers, which issued the initial permit for the project in 2018, according to Mitchell.
In the spring of 2021, Open Space and Trails staffers hope to get the local community involved with the project by having volunteers plant native sedges and rushes over the plug.
Already, community response to the restoration project has been very positive. Even without physical access to the fen, neighbors are excited about the prospect of improving habitat for wildlife, such as blue heron and elk, which they enjoy watching from their windows, Mitchell said.
“North Star can get a lot of negative attention surrounding the paddleboarding and recreation use, so it’s really nice to have another project that there seems to be widespread agreement on,” Mitchell said. “Everyone can get behind that it’s a pretty light touch for a pretty big benefit.”

The Grizzly Creek Fire in Glenwood Canyon has many people praying for rain. But the very thing that could douse the blaze, which has burned 32,000 acres as of Tuesday, has some experts concerned it also could create problems for downstream endangered fish.
A heavy rain could wash dirt — no longer held in place by charred vegetation — and ash from the steep canyons and gullies of the burn area into the Colorado River. Scorched soils don’t absorb water as well, increasing the magnitude of the flood. And the heavy sediment load in the runoff could suffocate fish. A similar scenario played out in 2018 when thousands of fish were killed by ash and dirt that washed into the Animas River from the 416 Fire burn area.
Downstream from the Grizzly Creek Fire, beginning in DeBeque Canyon, is critical habitat for four species of endangered fish: humpback chub, Colorado pikeminnow, bonytail and razorback sucker.
“Yes, we are very concerned about a fire in that kind of terrain that close to critical habitat. There’s just no question,” said Tom Chart, director of the U.S. Fish & Wildlife Service’s Upper Colorado River Endangered Fish Recovery Program. “There’s a probability we could have an effect all the way down into the 15-mile reach.”
The Colorado River’s so-called 15-mile reach, near Grand Junction, is home to those four species of fish. This stretch often has less water than is recommended for these fish by Fish & Wildlife mainly because of two large irrigation diversions that pull water from the river to irrigate Grand Valley farms: DeBeque Canyon’s Grand Valley Project, which takes water from the river at a structure known as the Roller Dam, and the Grand Valley Irrigation Canal, which takes water from the river near Palisade.
Between these diversions and the confluence of the Gunnison River is a problem spot where water managers constantly work to bolster water levels through upstream reservoir releases. According to Chart, there is currently a total of about 250 cubic feet per second being released from Ruedi, Wolford and Granby reservoirs for the benefit of fish in the 15-mile reach.
With hot, dry weather, a weak monsoon season and the ongoing diversions for irrigation season, which continue into the fall, current river conditions are already stressful for the fish, Chart said. Water managers say they have seen fish using fish ladders to swim upstream and downstream of the 15-mile reach in search of deeper, cooler water.
“As far as concern about the ecological health of the 15-mile reach right now, we are very concerned about conditions there right now,” Chart said. “Native fish do move out of those dewatered stretches in search of better conditions.”
A debris flow on top of these already-challenging conditions could be devastating for fish populations.
“The potential with the Grizzly Creek Fire could be as bad as it gets if we get a rainstorm on top of a low baseflow,” Chart said. “You pray for rain, but at the same time this would be a tough time to get a flow of ash and retardant off the burned area.”
Burned area assessment begins
The U.S. Forest Service’s Burned Area Emergency Response team has done a preliminary assessment of the severity of the soil burns to determine where debris flows would most likely occur, according to Lisa Stoeffler, deputy forest supervisor for the White River National Forest.
Areas of concern include Dead Horse Creek, Cinnamon Creek and No Name Creek, among others. More than an inch of rain in an hour — or a quarter-inch in 15 minutes, as occurs in a fast-moving thunderstorm — could trigger a debris flow, the BAER team found.
But this initial assessment, Stoeffler said, is mostly focused on potential impacts to Interstate 70, and water and power infrastructure, not on impacts to the aquatic environment.
“We may look at environment later on, once we have a final footprint of the fire,” she said. “The BAER process is really looking at things that we would need to address because it would cause an emergency-type situation.”
When the Grizzly Creek Fire first broke out, the city of Glenwood Springs switched its municipal water source from Grizzly and No Name creeks, which are near the burned area, to the Roaring Fork River.
“We are concerned about the ash and debris entering the water system and the costs we are going to incur because of this,” said Hannah Klausman, public information officer for Glenwood Springs.
Solution is dilution
Since preventing the dirty runoff from reaching the river would be difficult, if not impossible, in the steep, rocky terrain, the best bet, Chart said, would be tapping into upstream reservoir water to flush sediment and ash.
In other words: The solution to pollution is dilution.
The Roaring Fork River, which flows into the Colorado at Glenwood Springs, also would help dilute the ash and sediment before it got to the 15-mile reach. Some of it would probably settle out before it got there anyway. But that would do little to help native fish populations closer to the burn area. Although not listed as endangered, other species such as flannelmouth sucker, bluehead sucker and roundtail chub also could be impacted.
“We get concerned about the endangered fish the most, but it’s really the entire native fish community we need to be paying attention to,” Chart said.
The Colorado River Water Conservation District has some water in Wolford and Ruedi reservoirs that could potentially be used for a flushing flow. But it would take careful coordination between reservoir operators. And it could be a complicated juggling act to figure out how to accommodate all the different demands for that limited water supply, said River District chief engineer John Currier.
“I think we stand ready to try and figure out how to do something,” Currier said. “It will be a topic of discussion sooner rather than later.”
Managing the impacts of the burned landscape on the fish will be ongoing long after the fire is extinguished.
“I think this is going to be an issue for years to come,” Chart said. “That landscape is going to take a long time to heal.”

The city of Aspen is now under stage 2 water restrictions due to extreme drought conditions.
Aspen City Council on Tuesday unanimously passed a resolution to move from stage 1 restrictions to stage 2, acknowledging that as of Aug. 18, the U.S. Drought Monitor elevated Aspen and Pitkin County from severe drought to extreme drought conditions countywide…
The last time the city declared a stage 2 water shortage was in 2018.
“We haven’t received any sort of measurable rainfall in over a month and we’re already in stage 1,” he told council. “Current stream flows are around the lows that we had experienced in 2018 and forecasted precip and temperature projections are not looking favorable to ending this drought.”
Stage 2 necessitates a 15% to 20% reduction in water use citywide, along with some stricter rules that are mandatory rather than voluntary, which was part of stage 1 restrictions passed in July…
As such, watering of any lawn, garden, landscaped area, tree, shrub or other plant is prohibited from 9 a.m. to 5 p.m.
Alternating odd-even water schedules for addresses ending in odd numbers and even numbers are now mandatory.
Swimming pools can’t be filled with city water, and washing sidewalks, driveways, parking areas, tennis courts, patios, or other paved areas are not allowed.
Also, privately owned cars, other motor vehicles, trailers or boats cannot be washed except from a bucket and from a hose equipped with a positive shutoff nozzle.
New public or private landscaping installations are not allowed, with the exception that they are required as a minimum for erosion control of disturbed surfaces as determined by the city.
Staff will enforce the restrictions first by education and then by fines, which range from $500 for the first offense to $1,500 for subsequent offenses, as well as a disconnection of water services by the city.
Temporary rate increases for large water users also will go into effect to encourage efficient use of the commodity.
Without a citywide reduction in normal water usage, agricultural and recreational activities and fish and wildlife habitat along the Maroon, Castle, Roaring Fork and Colorado rivers will be more negatively impacted, according to city officials.
FromThe Snowmass Sun (Maddie Vincent) via The Aspen Times:
By Sept. 16, the new plant — which started being constructed in 2017 and has now been up and treating local wastewater for more than a month — will be fully working in tandem with the newly renovated current plant, creating a refined wastewater treatment system that goes beyond more stringent state and federal requirements and discharges cleaner water into Brush Creek.
“To see the water flow from that plant through this and actually go out to the stream, to actually see the clarity of the water that goes out to the stream is very gratifying,” Hamby said.
As Hamby stood in the sanitation district parking lot looking at the three buildings, he explained that the primary reason for creating this newly refined wastewater treatment system was the need to align with Regulation 85, the state Nutrients Management Control Regulation passed in 2012 to help reduce phosphorus and inorganic nitrogen pollution to Colorado waterways.
According to Colorado Department of Public Health and Safety documents, Regulation 85 established new limits for how much phosphorus and inorganic nitrogen could be in the clean water discharged from state wastewater treatment plants, new and existing, and put new nutrient monitoring requirements in place.
All 44 wastewater treatment districts in Colorado must meet these new requirements by specified dates, with Snowmass being one of the first on deadline due to its size and location in a priority watershed, as previously reported.
Snowmass Water and Sanitation District voters approved a mill-levy tax to help construct the new plant in May 2016 and the district also was able to sell $23.3 million in bonds for the project, Hamby said.
The total cost for the whole renovated system — including construction of the new plant and renovation of the current plant — is around $27.6 million, Hamby said. The district anticipates it will be about 1% over budget when the project is completed this fall, but will be able to cover the extra cost with system development fee revenue from village construction projects, he explained.
And once it is fully up and running, the improved wastewater system will be able to filter out phosphorus to 1 milligram per liter and nitrogen down to 11.4 milligrams per liter, Hamby said. This is even stricter than the state’s limit of 1.75 milligrams of total phosphorus per liter at the 95th percentile (or 95% level of all samples taken in a given year) and 14 milligrams per liter of total inorganic nitrogen for new treatment plants.
Utilizing aerobic and anaerobic bacteria, the wastewater moves between plants through various aeration tanks, clarifiers, filters, UV disinfecting light and eventually out to Brush Creek. The predominately biological nutrient removal process will take around three days from start to finish and have a multitude of automated data collection and monitoring in place along the way to ensure it all runs smoothly.
“The idea of the process is we go from no air, to very, very little air, to a lot of air … that helps grow different types of bacteria. Different steps get you different nutrient removal,” Fineran explained.
Fineran and Hamby said the type of treatment plant and refined process isn’t unprecedented, but that the district was able to carry out the $3.5 million worth of improvements to the current plant in-house, or without any outside contractors to do the work — a feat the three men are proud of and a part of the district’s cost-effective philosophy.
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.

The City of Aspen is in a stage one water shortage, citing continued drought conditions. The city will make efforts to reduce water usage by 10%, but water-saving measures for residents are voluntary.
After an exceptionally hot and dry spring, most Pitkin County is in a state of “moderate drought,” with some portions in a state of “severe drought” that applies to much of Western Colorado.
Steve Hunter, a hydrologist with Aspen’s utility office, said officials are keeping tabs on water conditions before they become problematic. Aspen’s main water supply, he said, has no storage and comes from Castle Creek and Maroon Creek watersheds.
“Right now we’re fine,” Hunter said. “But without storage, you don’t have a backup, so you need to be really cognizant of the supply and meeting the demand.”
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.

Flows in local rivers are peaking this week, with a spring runoff that is slightly earlier and lower than normal.
“It kind of depends on where you are, but on the Colorado (River’s) main stem, for sure, the peak is below average,” said Cody Moser, senior hydrologist with the Colorado River Basin Forecast Center in Salt Lake City.
But despite the lower-than-average flows, this weekend is probably one of the best of the year to go boating on local waterways.
Vince Nichols, owner of the Aspen-based rafting company Blazing Adventures, said this weekend’s relatively big water is akin to a powder day.
The company is running trips on the upper Roaring Fork River, especially the Slaughterhouse section between Cemetery Lane and Woody Creek, and doing so in accordance with Pitkin County-mandated social-distancing and cleaning guidelines due to the COVID-19 pandemic.
“This will likely be one of the high-water weekends of the year,” Nichols said. “For the next seven to 10 days, there will be really good rafting conditions on the Roaring Fork.”
Flows in the Roaring Fork, at its confluence with the Colorado in Glenwood Springs, are predicted to be 74% of average for April through June. According to stream gauges, the Roaring Fork appears to have hit its peak seasonal flow on June 2 at just over 4,000 cubic feet per second. The normal period for peak runoff at this location is between May 29 and June 23, at about 5,900 cfs.
Predicting the exact day of peak flows near Aspen is trickier. The forecast center is predicting a peak for the Roaring Fork in Aspen on Saturday, at 490 cfs, because of rain expected that day. The Roaring Fork at Mill Street was running at a daily high of about 330 cfs on Thursday.
There would be more water flowing through Aspen if not for the Twin Lakes Tunnel, which takes water from the Roaring Fork headwaters near Independence Pass to Front Range water providers. About 600 cfs of water from the upper Roaring Fork basin was being diverted through the tunnel Thursday.
“The challenge is we’ve got that big warmup and precipitation in the forecast in this weekend,” Moser said. “It’s kind of a tough call.”
The low runoff, despite a snowpack that was slightly above normal, is due to 2019’s dry late summer and fall, plus this year’s drier-than-average March, April and May. Dry soils and plants sucked up a lot of the moisture before it made its way into the streams.
According to the U.S. Geological Survey gauges, the Crystal River near Redstone appears to have peaked on June 2, at about 1,750 cfs. The Crystal at this location usually peaks between May 25 and June 18, at about 1,930 cfs.
Downstream on the Colorado, flows peaked in DeBeque Canyon, above Grand Junction, on June 2, at about 13,300 cfs. A typical peak is about 17,000 cfs between May 24 and June 12.
This year’s peak flows on the Colorado near Grand Junction were augmented by releases from several upstream reservoirs to the benefit of endangered fish in the 15-mile reach between Palisade and the Gunnison River, which flows into the Colorado in central Grand Junction.
Beginning May 29, Green Mountain Reservoir, Wolford Mountain Reservoir, the Moffat Tunnel and other water-storage facilities released water to enhance the Colorado’s natural peak in the 15-mile reach. The augmented high flows enhance fish habitat.
Ruedi Reservoir, above Basalt on the Fryingpan River, did not participate in the coordinated reservoir operations this year because there was not surplus water to contribute, said Tim Miller, a hydrologist with the Bureau of Reclamation who manages water levels in Ruedi.
“I was getting kind of worried about fill a month ago,” Miller said. “I was pretty sure we didn’t have extra. We haven’t received anything near average precipitation for part of April or all of May.”
Ruedi Reservoir, which can hold 102,373 acre-feet of water, is currently 79% full. Releases from Ruedi will decrease Friday to allow it to fill, bringing flows on the Fryingpan to 115 cfs. Miller said it could end up about 5,000 acre-feet short of filling this year, which usually happens in early July.

The city of Aspen is moving ahead on a project aimed at increasing the reliability of its water supply and environmental flows through what’s known as an “alternative transfer method,” or ATM.
But water managers will have to think outside the box since the usual process of an ATM is transferring water from agricultural to municipal use, and there isn’t much irrigated agriculture in the upper Roaring Fork River basin.
In Colorado, most water rights are held by irrigators. So when towns and cities want to increase their water supplies, they often turn to agriculture to secure extra acre-feet. Permanent water-transfer agreements, often derided as “buy and dry,” can harm agricultural communities and economies, and ATMs are seen as a way to reallocate water more fairly and sustainably from agriculture to municipalities.
These voluntary water-sharing agreements would allow local irrigators to temporarily loan their water to Aspen and get paid for doing so. The most straightforward way for this to happen would be for water-rights holders above the city’s diversions on Castle and Maroon creeks to loan their water to the city.
But according to Colorado’s Decision Support System, which is the state database that tracks irrigated land, there is no irrigated land above Aspen.
“Certainly, the easiest way to meet the most goals is to find water above the city,” said Jason Brothers, principal at Summit Water Engineers, the engineer on the project. “If that’s not available, we will have to look at creative ideas.”
Most of the irrigated acreage in the upper Roaring Fork River valley is grass pasture in the Woody Creek area.
Aspen’s ATM project is funded with a $183,356 grant from the Colorado Water Conservation Board, plus $15,000 each from the city and Western Resource Advocates. It would be the first program designed for a Western Slope headwaters municipality.
In addition to increasing city water supplies, a secondary goal of the project is to improve river flows for the benefit of the environment, especially in the reach of the Roaring Fork through downtown Aspen. In dry years, flows can fall short of the 32 cubic feet per second of water required by the CWCB’s junior instream flow right, which is meant to protect the river environment “to a reasonable degree.”
The 2015 Colorado Water Plan sets a goal of 50,000 acre-feet of water transfers through ATMs by 2030.
“I think that backdrop (of buy and dry) really kind of set the stage for more of a state focus on how do we meet our continuing water-supply needs and can we do that in a way that minimizes harm to ag,” said Alex Funk, agricultural water resources specialist for the CWCB.
According to the grant application, city officials say there are 2,800 irrigated acres in the upper Roaring Fork valley and tributary basins, which the team could explore for compatibility with an ATM program, and that if a third or a quarter of these irrigated lands were in such a program, it could yield 1,000 acre-feet of water.
City officials won’t clarify exactly where those irrigated acres are. The project is still in its infancy and officials don’t have many answers yet, said Steve Hunter, utilities resource manager for Aspen’s water department.
“We just kicked this off,” Hunter said. “I don’t see answers coming for months, if not the latter end of a year into the project.”
One of those creative opportunities Brothers mentioned could involve participation by Front Range water providers that divert water from the headwaters of the Roaring Fork River. The cities of Colorado Springs, Aurora and Pueblo divert water from the upper Roaring Fork through the Independence Pass Transmountain Diversion System via the Twin Lakes Tunnel.
“We are not just looking at in-basin ATMs, but exploring the concept of ATMs on the east slope and if entities would be willing to forego their diversions from the West Slope,” said Todd Doherty, president of Western Water Partnerships. “We are seeing if there’s a willingness between the stakeholders to even consider that.”
Transmountain ATM opportunities are still conceptual at this point, and a water transfer from a transmountain diverter to Aspen would be a break from the way ATMs are typically conducted. However, Funk said the CWCB would be supportive of a municipal-to-municipal transfer of water under the ATM program.
Doherty’s organization is based in Denver and is a Colorado Public Benefit Corporation. The city has contracted with WWP for $213,356 to complete Phase 1 of the ATM investigation, which will entail examining all the water rights that could potentially be available to participate in an ATM program and approaching the holders of those water rights to see whether they are interested. No water-sharing agreement will happen unless the irrigators think it’s a better deal than what they are growing, Doherty said.
“I think it will be a success if we can get a few, hopefully a few larger ones, that will help demonstrate to the other irrigators in the basin that maybe this deal is worth looking at,” Doherty said.

From the Glenwood Springs Post Independent via The Sky-Hi News (John Stroud):
Rivers are rising faster than usual throughout the Colorado and Roaring Fork river watersheds, as warm temperatures have led to early melting of the high-country snowpack.
Higher river flows have also drawn paddlers to the Glenwood Springs Whitewater Park, as the facility officially reopened this week with public health guidelines in place amid the ongoing coronavirus pandemic…
Commercial rafting is on hold until later this month or early June while guidelines are being developed for that and other tourist activities. Private boats are allowed on the rivers, but with social-distancing and other health guidelines in mind.
The higher river flows are the result of warmer-than-normal temperatures across Colorado’s Western Slope, and the lack of precipitation to add to the mountain snowpack in April, according to Ken Leib, hydrologist with the United State Geological Survey in Grand Junction…
Leib said the Colorado River could see peak flows earlier than usual if the warmer weather continues, or possibly an early peak and then a second peak in June if temperatures modify.
After the record snowpack during the winter of 2018-19, the peak flow on the Colorado River below the confluence with the Roaring Fork River in Glenwood Springs didn’t come until July 1, 2019, according to USGS historical data.
The flow last year topped out at 20,800 cubic feet per second (cfs), at a depth of 9 feet, 8 inches at the Glenwood measuring station.
Dating back to 1967, the highest peak flow at Glenwood was 31,500 cfs on May 25, 1984. The earliest peak flow came on May 20, 1996, at 18,200 cfs.
As of Thursday evening, according to realtime USGS data, the Colorado at Glenwood was flowing at 5,150 cfs with a depth of 5 feet, 8 inches — down from the Monday high this week of 6,000 cfs and 6 feet, 1 inch.
Just above the confluence on the Roaring Fork River at Veltus Park, the flow in the Fork was topping out at 1,200 cfs with a gage depth of 3 feet, 3 inches. The peak flow on the Roaring Fork at that location last year also came on July 1, at 8,960 cfs.
USGS data goes back to 1906 for that location on the Roaring Fork. The earliest recorded peak came on May 12, 1934, when the flow topped out at 4,100 cfs.
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.”
Sue Anschutz-Rodgers, the owner of Crystal River Ranch above Carbondale, has told the state she is making progress toward building two 55-foot-tall dams that would form two 500-acre-foot reservoirs on land she owns in the Four Mile Creek basin and along Dry Park Road.
The cattle and hay operation has been owned by the Anschutz family since 1966. Water attorneys for Anschutz-Rodgers and the ranch are in state water court seeking to maintain conditional water-storage rights tied to the two potential reservoirs: Sue’s Four Mile Reservoir No. 1 and Sue’s Four Mile Reservoir No. 2.
They would be located on ranch-owned land in the Four Mile Creek drainage and along Dry Park Road, respectively.
The dam that would form Reservoir No. 1 would be 55 feet tall and 950 feet long, and the resulting reservoir would inundate 22 acres with water. The dam for Reservoir No. 2 would be 55 feet tall and 800 feet long, and the reservoir would inundate 30 acres. Each reservoir would hold as much as 500 acre-feet of water. By comparison, Grizzly Reservoir on Lincoln Creek above Aspen holds 590 acre-feet of water and is formed by a 56-foot-tall dam that floods 44 acres of land.
Anschutz-Rodgers is a philanthropist and environmentalist whose brother Phil Anschutz is worth $12 billion, according to Forbes. She has served locally on the boards of the Aspen Valley Land Trust and the Thompson Divide Coalition, and Anschutz-Rodgers is listed on the application as general partner of Crystal River Ranch Co., LLC.
On March 13, her water attorney, Glenn Porzak of Boulder-based Porzak Browning & Bushong, told the court in a proposed ruling that Crystal River Ranch “has exercised reasonable diligence in the development” of the two dams and reservoirs. He also noted that “the measure of diligence is the steady application of effort to complete the appropriation in a reasonably expedient and efficient manner.”
As such, the ranch is requesting that the conditional water-storage rights tied to the two potential dams — rights first decreed in 2006 — be extended for another six-year period.
“I believe we have shown the necessary amount of work to show diligence and extend these conditional rights,” Porzak said.
Any start of the dams’ construction, Porzak said, “is still at a preliminary stage.”
Irrigating more than 600 acres
The water from the potential reservoirs could be used to irrigate 535 acres of land along Dry Park Road, which drains into the Roaring Fork River, and another 93 acres of land in the Four Mile Creek basin. Four Mile Creek flows into the Roaring Fork downstream of the Ironbridge golf course.
The Crystal River Ranch house and the main part of the sprawling 7,600-acre site is located just off Garfield County Road 108, which leads from Carbondale up to the popular Spring Gulch cross-country ski area. The section of the ranch visible from CR 108 is irrigated with water diverted from the Crystal River via the Sweet Jessup Canal.
Another section of the ranch where elk are often seen roaming the irrigated hay meadows is off Dry Park Road, which runs between CR 108 and 4 Mile Road. The land in Dry Park is currently irrigated with water diverted from Four Mile Creek via the McKown Ditch, which crosses the ridge that separates Dry Park from the Four Mile Creek valley.
The headgate for the McKown ditch on Four Mile Creek is about 1½ miles downstream from the Sunlight ski area.
According to its application, the 1,000 acre-feet of water that the ranch hopes to store would be used for four purposes: stock watering, piscatorial, wildlife and irrigation. (Piscatorial pertains to fish.)
Crystal River Ranch filed its initial water-rights application for the two potential dams in Division 5 Water Court in Glenwood Springs in 2006. After working through some issues with five other water-rights holders in the case, a conditional water-rights decree for the two dams and reservoirs was issued by Judge James Boyd in 2013.
The 2013 decree required Crystal River Ranch to submit a due-diligence application in 2019 in order to maintain the conditional water rights.
In the diligence application, Porzak said since 2013 the ranch has spent $70,000 to “survey the reservoir sites; prepare layouts of the dams and reservoirs; (and) design work on the spillways, inlets, and outlet infrastructures of the reservoirs.”
A portion of the $70,000 also went to “design irrigation improvements and conduct layout of the pumps and sprinklers for the lands to be irrigated by the reservoirs; conduct a hydrology analysis for each reservoir site; drill boreholes at each reservoir site; test soil samples and perform a geotechnical analysis of each reservoir site; and prepare cost estimates for each reservoir site and all of the associated infrastructure.”
In reviewing a diligence application, the division engineer and the water court’s referee, who functions as an administrative judge, apply a standard of diligence. The standard is often met by the applicant listing the work they’ve done on the potential facilities that are tied to the water rights and are necessary to put the water to use.
“You have to show you are moving forward in a reasonable manner,” said Alan Martellaro, the Division 5 engineer.
No entities filed a statement of opposition to the application.
Martellaro reviewed the diligence application along with Susan Ryan, the water court’s referee, and then filed a memo — called “a summary of consultation” — with the court Feb. 28.
The summary said Crystal River Ranch “should provide reports and other documents, which support the diligence activities performed within the relevant diligence period as claimed in the application.”
To date, however, none of these documents have been filed with the court, and only a hard-to-read map of the general area where the reservoirs would be located has been made public.
Porzak said the work done on the two potential reservoirs has not yet been reduced to final written reports.
He also said that the activities in the diligence application were verified under oath by Craig Ullmann, the engineer who oversaw the work. Ullmann is president of Applegate Group Inc., a water-engineering firm with offices in Glenwood Springs.
Martellaro said the word “should” in the court’s summary of consultation means “should,” not “must,” so it is not clear whether the design documents for the two dams will be made public through the court process. He also said the documents cited in the application would be helpful for the state to have on file for the next diligence filing.
Porzak said all the relevant information was contained in the application.
Should the dams ever be built, the associated water rights would hold a priority date of 2006, a junior right under Colorado’s system of prior appropriation. As such, Crystal River Ranch couldn’t count on the water being there to store in dry years, Martellaro said.
“It’s a really junior water right on a stream that’s over-appropriated,” he said. “This is one of those creeks that just doesn’t have surplus. They are pretty much limited to snowmelt runoff to fill these ponds.”

Although snowpack in the mountains near Aspen is hovering above normal for this time of year, streamflows in the Roaring Fork River are predicted to be just 85% of normal for April.
The snow-telemetry, or SNOTEL, site at Independence Pass, near the headwaters of the Roaring Fork River, is at 106% of normal snow-water equivalent. The SNOTEL site at Kiln, near the headwaters of the Fryingpan River, is at 106% of normal. And at Scofield Pass, home to the headwaters of the Crystal River, the SNOTEL site shows snowpack at 90% of normal. The Roaring Fork basin as a whole is at 112% of normal snowpack.
But the April water-supply outlook released by the National Resources Conservation Service predicts streamflows at just 85% of normal at the confluence of the Roaring Fork and Colorado rivers in Glenwood Springs.
“It’s kind of an anomalous year,” said Karl Wetlaufer, a hydrologist with NRCS and assistant supervisor with the Colorado Snow Survey. “More commonly, the streamflow forecasts do pair with the snowpack pretty well.”
The reason for the discrepancy is dry soils, which soak up spring snowmelt before it gets to streams. According to the U.S. Drought Monitor, abnormally dry conditions crept back into Pitkin County in mid-September. By Oct. 22, the western half of the county was in severe drought, while the eastern half was in moderate drought. The western half of Pitkin County is still experiencing either abnormally dry conditions or moderate drought.
“All of late summer was really dry, but before the snow started to accumulate, it was extremely dry,” Wetlaufer said. “The soil can be like a really dry sponge right now and soak up more runoff than usual.”
That lower-than-normal runoff could have impacts on the city of Aspen, which takes its municipal water supply directly from Castle and Maroon creeks. Tyler Christoff, director of Aspen’s utilities department, said city staff is constantly monitoring the variables in the watershed — U.S. Geological Survey gauges, SNOTEL sites, weather forecasts, Drought Monitor — but so far, they are treating this as an average year.
“Being close to average, we are going to let it play out and see if there’s any action we need to take,” Christoff said. “I think regardless of the year and the season, it’s important for our community to be conscious of our use of water as a resource; we do not have an unlimited supply.”
The Colorado River basin typically reaches its peak snowpack for the year in early to mid-April.
NRCS has two main ways of measuring snowpack, which feed into the water-supply forecasts. The first is through SNOTEL sites, which are an automated system of sensors that collect weather and climate data hourly from 115 areas around Colorado, mostly in remote, mountainous watersheds between 9,000 and 11,000 feet. They measure snow depth, water content of the snow, precipitation and air temperature.
The other way is through snow courses, which are manual measurements of snow depth and water content.
But due to the COVID-19 crisis, NRCS staff did not conduct end-of-March manual snow surveys. Wetlaufer said the agency wanted to follow social-distancing guidelines and not have employees traveling in the same vehicle to remote mountain communities.
“We need to go out in pairs for backcountry work,” he said. “We have been talking about options for next month. Some sites that are key, maybe we can still go out and drive two vehicles.”
But streamflow forecasts for the Colorado River basin barely use any snow-course data, Wetlaufer said, so those forecasts should still be accurate without the manually collected data.
“In the Colorado River basin, there’s really pretty minimal impact,” he said.

Pitkin County’s Healthy Rivers board is moving ahead with a nearly $1 million project to fix a problem spot on the Roaring Fork River between old town Basalt and Willits.
For the past few years, the board has been steadily accumulating grant money to fix the Robinson Diversion, an area known to boaters as Anderson Falls. The diversion is a line of rocks across the river, designed to help water flow into a channel on river right and into the headgate of the Robinson Ditch.
The spot, just upstream of the small boat ramp on Willits Lane near the FedEx outlet, has long presented a tricky obstacle to boaters, especially at low water.
And although repairs last April by the ditch company created a much-improved boat channel, the area remains vulnerable to winter ice flows and spring runoff, which could rearrange the rocks. Pitkin County is hoping to fund a more permanent fix.
Last month, Healthy Rivers board members informally decided to move forward with restoration project “option A” with an estimated cost of $935,000.
The work, by Carbondale-based River Restoration, would include creating two smaller drops in the river, instead of one large drop, which would still allow water to reach the Robinson Ditch’s headgate. The project also would make some improvements to the diversion structure and result in better fish habitat.
River Restoration also presented Healthy Rivers with an “option B,” which would modify the existing rocks and extend the drop downstream to make for a more mellow ride in a raft, ducky or kayak. That option would cost roughly $586,000 but would not include fish-habitat work or improvements to the diversion headgate.
Board members decided to stick with the more complete “option A.”
“We might be wasting money if we don’t go big on this project,” said Healthy Rivers board member Lisa Tasker. “Going big means finding a solution to the Robinson Ditch rearranging the river bed year after year. One of the biggest goals is to have less equipment get into the river.”
Pitkin County commissioners have to approve expenditures from the Healthy Rivers board, which is a recommending body.
Blazing Adventures runs commercial river trips from Snowmass Canyon to just below the Robinson Diversion structure, usually starting in July as spring runoff fades. Owner Vince Nichols said the boat chute last year was a great improvement, but he would welcome a more permanent fix.
“Our main takeaway would be safety and having a boatable passage,” he said.
It’s unclear yet whether the Robinson Ditch Co., which owns and operates the structure and headgate, will contribute monetarily to the project, but manager Bill Reynolds said he is in support of fixing the structure.
“I welcome anything that helps all the boaters, fisherman, all the users on the river,” he said. “And if the ditch company can gain a better structure out there, that will help everybody. It’s a win-win.”
These are matching grants, with the county currently committed to contributing at least roughly $246,000 toward the project.
According to Lisa MacDonald, a paralegal in the county attorney’s office, Healthy Rivers has no other grants in the works for the project, but it continues to look for more opportunities and funding. The project is still short of funding by about $430,000, and as time goes on, project costs continue to rise.
The price tag on the project in 2017 was $800,000. By this year, it had increased to $935,000.
“(The project) has a large footprint and we have to move the river during construction,” said Quinn Donnelly of River Restoration. “There are so few contractors that do the work, and it’s involved. There is risk involved.”
To make up the funding gap, MacDonald said the county could seek contributions from Eagle County, the town of Basalt, the ditch company and grants from Great Outdoors Colorado.
“The board does need to talk about exactly where the rest of that funding will come from,” Tasker said. “We are moving forward and will have discussions about how to cover what our grants do not.”

The National Environmental Policy Act, or NEPA, turned 50 years old on Jan. 1. A fundamental component of the law is public involvement. Projects such as a new ski lift, trail or natural-gas lease each receives a NEPA review, and most of the time the public weighs in. NEPA has evolved over the years, but the biggest change may come in a new proposal from President Donald Trump.
A NEPA case study: The trail between Redstone and McClure Pass
Katherine Hudson lives near the Crystal River between Carbondale and Redstone. She said she loves living close to nature but thinks a proposed multi-use recreation trail will disturb the river.
“For me, it’s not just about the view,” she said. “I value this incredible waterway and how lucky we are to have it.”
Hudson, a member of the Pitkin County Healthy Rivers Board, believes bridges planned along the trail will constrict the river.
A five-mile section of the proposed trail sits on Forest Service land and will get, thanks to NEPA, a close review. Hudson was one of about 50 people looking over maps and visiting with Forest Service staff at an open house in Carbondale in late January.
Under NEPA, federal agencies must consider impacts to the environment when projects such as the Redstone to McClure Pass Trail are proposed on public land. The law applies to all major federal actions, including infrastructure permitting and road construction. One goal is to “create and maintain conditions under which man and nature can exist in productive harmony,” according to the Environmental Protection Agency.
Proposed changes from Washington
In January, the White House released a plan to streamline NEPA, marking the first major update in decades. The changes would impose strict deadlines on completing analyses; would more closely involve contractors in studies; and would eliminate requirements to consider climate change.
“It would make it really difficult to analyze the impacts on climate in any project,” said Will Rousch, executive director at Wilderness Workshop, a public-lands watchdog group based in Carbondale. “It would redefine what a major federal action is. That might eliminate some projects from going through the NEPA process.”
Also, he said, fewer projects undergoing a review means fewer opportunities for the public to weigh in.
But supporters say NEPA has become time consuming for federal agencies, project applicants and people seeking permits.
U.S. Rep. Scott Tipton, a Republican from Colorado, points to a NEPA review of an Interstate 70 project near Denver that took 13 years to complete. He said lawsuits and reviews from multiple agencies kept it from moving forward more quickly.
“This was a good example of how we do need to make sure that we’re doing the right thing environmentally but also that we’re not creating roadblocks that stifle any kind of development at all,” Tipton said.
Local efforts to make NEPA more efficient
President Richard Nixon signed NEPA into law in 1970. Two catastrophic events prompted its creation: Millions of gallons of crude oil leaked into the Pacific, and a heavily polluted river in Ohio caught fire. Now, agencies such as the White River National Forest use the law all the time.
“It’s part of our work daily, for sure,” said WRNF supervisor Scott Fitzwilliams. “We use NEPA on almost every single project. But there’s varying levels of it.”
For large, complex projects, a team of scientists may analyze a project’s impacts and create alternatives informed by public input. Small-scale projects, such as replacing a trailhead sign, don’t get in-depth reviews and public comments. The Forest Service determines how a project is analyzed based on its significance.
The White River National Forest, like the Trump administration, sees ways to make NEPA more efficient. The agency has developed tools that reduce the time it takes to do an environmental analysis. Their work began with a Forest Service-wide effort in 2017. The White River National Forest’s efficiencies have reduced NEPA document size and planning by more than 80% compared with the national average.
“We’re trying to be more efficient with the taxpayer’s money and really streamline where it’s appropriate,” Fitzwilliams said. “That doesn’t mean we cut corners; we still have a responsibility to disclose impacts, consider alternatives and involve the public, but we want to do it in a way that’s a little less bureaucratic.”
Since the streamlining began, Fitzwilliams estimates his agency has saved time and money by not conducting three environmental-impact statements — the most-in-depth analyses — that would have been done before. An EIS is still utilized, he said, if a project is significant enough.
“We’ve been doing less EIS’s and more EAs (environmental analyses),” said Fitzwilliams.
The approach began with ski areas. Hundreds of NEPA analyses have been done on ski hills in the White River National Forest, so a new project, such as a lift, may receive a lighter review because previous studies help inform it.
“We know the ground really well, and so we really focus on what the key issues are,” said Fitzwilliams. “Instead of doing a full specialist report on all the wildlife potential impacts, we may just focus on elk-calving areas.”
The agency isn’t cutting corners, he said, and still focuses on considering impacts, alternatives and public involvement, the latter of which remains a high priority.
“People expect that of their government,” Fitzwilliams said. “They don’t expect government to waste time and money just because.”
The White River National Forest’s efforts to innovate NEPA earned the agency national distinction in December at the Under Secretary’s Awards and Chief’s Awards ceremony in Washington, D.C.
What’s next locally and nationally?
The NEPA process for the Redstone to McClure Pass Trail is just getting started. It will take one year to complete, partly because it’s contentious. It’s getting an environmental assessment — a middle-ground approach under NEPA. It’s neither the law’s deepest analysis nor its lightest-touch approach, and the public will have two chances to give feedback.
The concerns raised at the open house — river health, maintaining biodiversity and preventing habitat fragmentation — will inform the final assessment.
“It’s an issue that a lot of people care about, and I think without the NEPA process, you’d end up with a much worse project regardless of how it turned out because people wouldn’t get a say,” said Rousch.
Hudson said she’s glad for the opportunity to comment on the trail project.
“I’m in it for the long haul because there are a lot of things that are at stake,” she said. “The Crystal River is a jewel of this watershed, and decisions could be made with this project that could permanently alter that treasure.”
She said she will submit concerns during both comment periods.

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 Sunday, a group of roughly a dozen locals took part in this snow science method as well, collecting core samples and learning about how snowpack contributes to watersheds during a “field trip for adults” in the Marble area.
Led annually by the Roaring Fork Conservancy and United States Department of Agriculture Natural Resources Conservation Service officials for the past six years, the daylong, hands-on snow science education course has aimed to help locals see snow as integral to our ecosystems year-round, not just as a recreational benefit in the winter, according to Megan Dean, director of education for Roaring Fork Conservancy…
…[Megan] Dean said the Roaring Fork watershed contributes about 11% of the water that goes into the Colorado water basin, mostly because the valley’s mountains capture and hold a great deal of water via snow…
After Dean touched on geographic climate trends and key snow science definitions — like the snow water equivalent, which is the actual amount of water in a given volume of snow — soil conservationist Derrick Wyle jumped in to talk snowpack data.
According to Wyle, who works with the USDA’s Natural Resources Conservation Service, snowpack, precipitation, temperature and other climatic conditions are collected consistently throughout the winter season at NRCS SNOTEL sites…
So far this year, Wyle said historic and current data for the Colorado water basin show snowpack is about average for this time of year, with a “coin flip chance” of being above or below average for the whole season…
During the second half of the Sunday field trip on McClure Pass, Wyle and Dean showed the group both how to look at snow depth, density and the snow water equivalent manually using a [Federal Snow Sampler] and by digging a snow pit, and how the McClure Pass SNOTEL station works to collect the same data on its own.
From small measurements to big picture graphs and newer technology to traditional scientific methods, Wyle and Dean aimed to give the group a snow science crash course and to help put the snowpack numbers they may hear in passing or see online into perspective.
Pitkin County will begin construction next week on the latest fix to a whitewater park on the Roaring Fork River in Basalt that some said was too dangerous during high water last summer, sources said Wednesday.
“The primary goal of the adjustment is to improve high-flow navigation from runoff,” said Quinn Donnelly, an engineer with River Restoration of Carbondale, which designed the park. “(High water) was creating big holes and people were flipping.”
Contractors next week will begin altering two man-made concrete wave structures in the riverbed to make them less difficult to navigate during high-water conditions, Donnelly said. Crews will move around boulders and create ramps to better flush water through the area and create a wave-train, he said.
“The goal of this winter’s work is to strike a better balance between the fun surfability of the waves and their high-water navigability,” Pitkin County Healthy Rivers and Streams Board Chairman Andre Wille said in a news release Wednesday. “The end result will be wave features that are easier for river runners to bypass at high flows.”
Despite repeated requests Wednesday for how much the project will cost and where the money will come from, a spokesperson for the Pitkin County Healthy Rivers and Streams Board declined to release it. The park was initially built for $770,000 with Healthy Rivers funds, though it’s not clear how much has been spent since then to tweak it.
This winter’s project will mark the second time the whitewater park has had to be re-engineered because of safety concerns.
Snowfall in Aspen is pacing well ahead of average this ski season thanks to a big opening blast in October and above-averages dumps in December.
The Aspen Water Treatment Plant recorded 84.70 inches of snowfall for October through December, according to the monthly weather reports. That is 28.45 inches or 51% above the average of 56.25 inches, according to the water department’s records.
Each month has been well above average at the plant, which is situated at 8,161 feet, slightly above downtown Aspen’s elevation. The cold-weather months started with a bang when 26.70 inches of snow fell in October. The average is 9.20 inches.
November was closer to typical conditions when 23.50 inches fell, the water department reported. The average snowfall for the month is 21.90 inches.
December kept the trend going with 34.50 inches of snowfall, well above the average of 25.15 inches.
None of the months came close to breaking a record for snowfall. The December record, for example, is 72 inches in 1983.
More snowfall than usual at the 8,100-foot level hasn’t translated into a significantly higher snowpack than average at higher elevations. The snowpack at the headwaters of the Roaring Fork River east of Aspen is at 107% of median as of Friday, according to the Natural Resources Conservation Service, a federal agency that has automated snow telemetry sites scattered around the Roaring Fork watershed.
The snowpack at the Independence Pass site was at 7.7 inches of snow water equivalent — the amount of water produced when the snow is melted. Last year on the same date it was 7 inches.
The snowpack at the headwaters of the Crystal River Valley was 97% at Schofield Pass and 97% at McClure Pass as of Friday.
The snowpack at the headwaters of the Fryingpan River Valley was 147% at Ivanhoe Lake and 131% at Kiln, according to the snow telemetry sites.
Approaching Labor Day weekend of 1961, many Aspenites who had plans to go camping or enjoy outdoor concerts watched in trepidation as monsoon rains didn’t let up for two days. Then, that Friday night, the damp chill turned rain to snow — large, wet snowflakes fell overnight and for the next two days, thoroughly coating the green, late-summer landscape. Tree limbs bent and snapped, the music tent started to rip under the weight of the snow, motorists were stranded when Independence Pass closed and the power went out in the city for two days.
“It was a hell of a mess,” said lifelong Aspenite Jim Markalunas.
The mayor called Markalunas and asked him to reboot the defunct hydroelectric plant he had previously run while the regional electric utility struggled to restore the downed lines.
He managed to restore power to Aspen, and by the time residents woke up to a cold, sunny Labor Day morning, 27 inches of snow had fallen in town, a record that still stands, according to Markalunas, author of “An Aspen Weather Guide” and “Aspen Memories.”
Now 89, Markalunas also has tales of being surrounded by massive snowbanks as a 6-year-old in the 1930s and worrying about roofs collapsing from the heavy-snow years of the 1980s.
“Big snow years are oh-be-joyful for the (Aspen Skiing Company) and skiers but made for a lot of hard work for people maintaining the streets and intakes and such,” he recalled.
Markalunas remembers lean years, too, most notably the winter of 1976-77. That ski season didn’t start until January and recorded just 86 inches of snow all winter. It also spurred massive investments in technologies to battle drought impacts, such as snowmaking and cloud-seeding.
Markalunas likes to say that Aspen’s weather is “consistently inconsistent.” But he started noticing a difference in patterns in the 1980s — in particular, less-frequent below-zero temperatures.
“The trend is we just don’t have the super-cold weather we used to have,” he said, pointing to weather data he has compiled from water department records showing that Aspen has hit a low of less than minus 20 just once since 1997.
“It seems as though the weather pendulum swings more extremely than in years of old,” Markalunas writes in “An Aspen Weather Guide.” “Storms are more violent but less frequent. The weather appears to be more volatile than in past years. … Unless we act to decrease carbon dioxide emissions, ski racks on SUVs might become useless accessories here.”
Markalunas’ observations are supported by other data, analyses and studies that paint a picture of a changing local climate. Pitkin County is warming, the number of frost-free days is increasing and snowpack is declining — all of which have myriad impacts on recreation, the ecosystem, wildlife, streamflow, water availability, droughts and wildfires. One of the most notable impacts is on the underpinning of modern Aspen’s economy: snow and skiing.
Officials at Aspen Skiing Company, or SkiCo, have been aware of changing temperatures and snowfall for some time. Like others, the biggest change that Rich Burkley, SkiCo’s senior vice president of strategy and business development, has seen in his 30-year career is more variability.
“It’s a feast of riches or famine, and you have to deal with that,” he said.
Pitkin County’s average temperature has been rising at a rate of 0.4 degrees per decade since 1950, according to the National Oceanic and Atmospheric Administration. In 2018, the average temperature throughout the year in Pitkin County was 39.5 degrees — 2.9 degrees warmer than the mean temperature during the baseline period of 1950-75.
More-dramatic changes are happening in the cold-season months. Temperatures are rising almost half a degree per decade between November and April, compared with about one-quarter of a degree the other half of the year.
March is by far the fastest-warming month, heating up at a rate of 1 degree per decade since the 1950s. The average temperature of 34.4 degrees in March 2017, when Aspen hosted the World Cup ski racing finals, was a record 9.4 degrees higher than the 1950-75 baseline temperature.
The race venue on the lower half of the mountain lost several inches of snow surface per day, Burkley said. The only reason there was enough snow to race on was extra early-season snowmaking that at the time was considered excessive.
Markalunas’ theory of fewer really cold days shows in this data as well. Average annual low temperatures have risen in Pitkin County and appear to be accelerating — average minimum temperatures were more than 5 degrees higher than the baseline during three of the past five winters.
“Even since 1980, there has been a pretty sharp annual average temperature increase over time,” said Elise Osenga, research and education coordinator for the nonprofit Aspen Global Change Institute, or AGCI. “Even just a couple degrees difference is a notable difference in annual average temperatures — especially if you are a seasonal-sensitive plant or animal.”
A 2014 report by AGCI notes that rising low temperatures, particularly in early winter, can affect the ability to make snow on the ski mountains, an activity typically limited to November and December. This hasn’t impacted SkiCo much yet, according to Burkley. Snowmaking now is about twice as efficient as it was two decades ago, thanks to automation and improved technology.
SkiCo also has plans to expand snowmaking to the top of Aspen Mountain next season, which Burkley said will be key to Thanksgiving openings as the upper part of the mountain often doesn’t have enough natural snow in November.
Zooming out, a recent Washington Post feature found that Pitkin County and much of the Colorado Rockies are warming faster than other places. Pitkin County’s average temperatures have risen 2.34 degrees since 1895, at the height of the Industrial Revolution; the average across the United States is 1.8 degrees. In fact, western Colorado and eastern Utah comprise a large “hot spot” that warns of greater climate shifts to come.
Freezing? Not so much
One critical trend related to rising temperatures — in particular, rising low temperatures — is an increase in the number of frost-free days, which AGCI counts as consecutive days of above-freezing temperatures from the last freeze of spring to the first time it dips below 32 degrees after that. Like temperature, the number of frost-free days has risen sharply in recent decades.
Since the 1980s, there’s now an additional month each year without freezing temperatures in Aspen, according to AGCI’s analysis. The actual number of days above freezing varies widely from year to year, but there is a clear upward trajectory, as seen in the Forest Health Index, which is produced by the Aspen Center for Environmental Studies with help from AGCI.
Higher temperatures mean less snow
Changes are, of course, also being felt beyond ski-area boundaries. In the summer of 1994, big-mountain skier Chris Davenport first skied 14,092-foot Snowmass Mountain, named for the massive snowfield that historically stretched across a wide bowl below its summit.
“In the next decade or so, it seemed like that permanent summer snow was getting smaller and smaller, until one summer in the mid-2000s, it was totally gone,” said Davenport. “It’s a direct effect of warming — even if it’s a few degrees, that snowfield couldn’t hang on.”
Winter snow might still linger into the summer months on Snowmass, Davenport said, but most years, the formerly year-round snowfield is gone by mid-July.
The waning snowfield on Snowmass Mountain is representative of a larger trend. Summer snow covering the Northern Hemisphere receded from 10.28 million square miles at its peak in 1979 to a low of 3.69 million miles in 2013, according to Climate Central’s website WXshift.com. Not only does that impact water supplies, but less snow cover means more sunlight absorbed by Earth, driving a feedback loop of further temperature increases.
Snowfall has also decreased in many parts of the United States, according to the Environmental Protection Agency, although no significant trends in precipitation have been found in the Aspen area or Colorado in general. Some climate models predict more precipitation in the future, but rising temperatures could mean that precipitation comes more often as rain rather than snow.
In Pitkin County, as in the American West and other mountain drainages around the world, snowpack is arguably the most consequential climate-change indicator. Mountain snowpack not only determines availability of snow for recreation but also how much water will be available for all manner of natural and human uses. In Colorado, including the Roaring Fork River valley, snowpack — usually measured by the amount of water in the snow, known as snow water equivalent, or SWE — is generally variable and can range widely from year to year. But this, too, has become more extreme in recent years.
“We’ve observed these huge year-to-year shifts,” said Karl Wetlaufer, a hydrologist with the U.S. Department of Agriculture Colorado Snow Survey, which collects and manages snowpack data. “So that does feel like a trend: Over the last 15 years, things seem to be much more erratic, with more extreme years on both high and low ends.”
The scientific community considers the April 1 snowpack the peak of the water year. Only once since 2010 has the Roaring Fork basin’s snowpack on April 1 been measured between 85% and 115% of normal, said Wetlaufer. That range was more common in earlier periods.
The last two winters feature some of the wildest snowpack swings — and the most extreme weather events. From October 2017 to September 2018, snowpack peaked at 72% of normal; the following snow season, it peaked at 144%.
The low-snow season resulted in such tinder-dry conditions that the Lake Christine fire, the most threatening fire in recent valley history, burned for months in the summer of 2018. That was followed by a winter capped off with an unprecedented avalanche cycle, the result of a steady buildup of the snowpack on a weak base layer, ultimately unleashed by a massive storm cycle that was fueled by warm atmospheric rivers from the Pacific Ocean.
Besides more variability, some recent scientific analyses, including this map produced by the EPA and AGCI’s 2014 report, have found that Colorado’s snowpack is decreasing. A study published by Peter Goble and Nolan Doesken of Colorado State University’s Colorado Climate Center found that central Colorado’s snowpack is diminishing by an average of .49 inches of SWE per decade, which was the most of the four regions studied. This calculation includes measurements taken at a station near Independence Pass.
A half-inch of SWE can equate to 7.5 to 10 inches of snowfall, Goble said, which over 100 years could mean 75 to 100 fewer inches of snow — about one-third of the roughly 300 inches that fall on average on the Aspen Snowmass slopes.
“Considering that loss may accelerate, those numbers look a little threatening to the local lifestyle,” said Goble.
Recent research also accounts for factors such as dust on snow, likely to be more frequent in the future given the increasing aridity of areas west of Colorado and more human disruption of those areas. Dust on snow, similar to rain on snow, melts the snowpack more quickly.
Scientists agree that the main factor contributing to a declining snowpack is not less snowfall but warmer temperatures due to increased greenhouse-gas emissions. And because temperatures are expected to continue to rise — the amount depends on how much emissions are curbed — snowpack around Aspen and elsewhere will continue to decline.
Still, Goble is hopeful.
“When you look at the projections and how winters might change, it’s not a totally hopeless situation,” he said. “We still have control over our future. If this is a problem humans take seriously and we see a lot of action on a large scale over the next couple decades, it will make the outlook for the back half of the century a lot brighter than if it was business as usual.”
AGCI’s 2006 report for the city of Aspen, on the other hand, painted a dire scenario for future skiers (as well as downstream water users) with continued warming, including the potential for shorter ski seasons and substantially reduced snow cover.
Aspen Mountain will still be skiable in 2030 under all emissions scenarios, the report concluded, but “by 2100 the base area of Aspen Mountain has essentially lost a skiable snowpack, with the exception of the lowest greenhouse-gas concentrations.”
In all future emissions scenarios, the AGCI report found that Aspen Mountain’s base snowpack will start to accumulate later in the fall and melt earlier in the spring due to warming temperatures. Snow depths at all elevations are projected to be reduced throughout the season. In the worst-case scenario, the ski season will be 10 weeks shorter by 2100 and “snow depth goes to near zero for the entire lower two-thirds of the mountain.” That’s everything below the base of the Ajax Express chair.
“Under these scenarios, some of our seasons are shortened and our terrain could be reduced,” Burkley said. “We would be in download situations more frequently. We would build and concentrate snowmaking at higher elevations. We might have more hike-to or hike-out terrain. We would build lifts to access areas that have more consistent snowpack.”
Burkley said with existing infrastructure, SkiCo can offer lift-served, high-elevation skiing on three mountains. The proposed 180-acre Pandora expansion on top of Aspen Mountain also would expand into terrain that “will probably have the best snow in the future.”
Even as SkiCo relies more on snowmaking, Burkley acknowledges minimum streamflow requirements could be an additional challenge. There could be a time when natural snowpack declines to the point that there won’t be enough water in local streams to make all the snow it needs, in which case the company might have to decide to shut down one or more of its four mountains and focus efforts on what remains open.
SkiCo is also increasing its focus on summer operations, including Snowmass Bike Park. For now, this helps ensure a return on expensive infrastructure; later, it could help make up for shorter winters.
Ironically, the Aspen Snowmass ski areas could actually benefit in the short term from climate change. They’re situated at higher elevations with colder temperatures than many other resorts, especially those outside of Colorado, and could see increased visitation as lower-elevation ski areas become less viable.
Clearly, Aspen isn’t the only ski resort facing an existential crisis. Ski areas across the country are recognizing the challenges that climate change poses to their viability, and that’s provoking a shift in industry thinking.
“In recent memory, climate was an uncomfortable conversation. Resorts said it was politicized science,” said big-mountain skier Davenport, who is now a climate activist and board member of the advocacy group Protect Our Winters, or POW. “Now everyone’s on board.”
The scale of action is bigger than resorts switching to renewable energy or lobbying for climate-friendly policies in Washington, D.C., as SkiCo has been doing for years. Three of the largest industry groups — Outdoor Industry Association, Snowsports Industries America and National Ski Areas Association — recently formed the Outdoor Business Climate Partnership to provide leadership and inspire action on climate change. Using POW’s playbook, SIA launched United by Winter, a climate-advocacy platform for its members. And POW is now on the radar of elected officials in every state where the outdoor industry has a presence.
“It used to be inconvenient for outdoor companies to talk about climate change, but now the opposite is true: If you’re not having that conversation, consumers aren’t buying from you,” Davenport said. “Look how we’ve changed the conversation.”
Untreated, polluted water flowing into the Roaring Fork River in the heart of Aspen and failing underground storm water infrastructure has the municipal government looking for new revenue streams to put toward an underfunded clean river program.
The city has made progress with capturing and filtering runoff before it hits the Roaring Fork from the Aspen Mountain basin on the south side of the river, with catch basins and wetlands near the Rio Grande park and trail.
But on the north side of the river, where east end neighborhoods and homes on Red Mountain are located, untreated storm water runoff goes directly into the Roaring Fork.
That is one likely cause of why the state has put the Roaring Fork on its watch list of impaired waterways, said April Long, the city’s clean river program manager.
Long has been charged with finding new revenue sources to fund the storm water department and clean river program in which almost $19 million in capital projects have been identified.
Ramping up the program is a priority that Aspen City Council zeroed in on earlier this year as it learned it is woefully underfunded…
The main funding source for the clean river program now is a property tax passed by voters in 2007 and put in place in 2008. It generates about $1.2 million annually.
But with underground corrugated metal pipes that are more than 40 years old and are rusting out, replacing just a third of the infrastructure is anticipated to cost $4 million, according to Long…
City Engineer Trish Aragon noted it costs more to replace pipes in emergency situations, and getting out in front of it is a better use of taxpayer money…
The department has identified just under two dozen projects that would create a more robust clean river program and address some of the state’s concerns.
One of them that will get some preliminary attention next year is designing a catch basin on the north side of the river at Mill Street and Gibson Avenue, near the old powerhouse.
It would collect runoff from the east end residential complexes including Hunter Creek and Centennial and some of Red Mountain…
Long and Aragon are beginning to look at funding options based on what other municipalities do, as well as other research and brainstorming exercises.
The establishment of some type of fee, along with grants and creating special districts in neighborhoods where the infrastructure needs to be done are options on the table.
Long said she plans to bring funding options, along with prioritized projects with timeframe scenarios to council sometime next year.
The fight over damming the Crystal River has been resurrected, this time before there are even any dam projects to fight over.
The Colorado Basin Roundtable voted Monday to recommend the state give $25,000 toward a water study in the Crystal River basin, despite calls from some to deny the Water Supply Reserve Fund request because of concerns that a study might conclude there is a need for water storage.
The Colorado River Water Conservation District and the West Divide Water Conservancy District brought the grant request to the roundtable in Glenwood Springs in an effort to solve a long-acknowledged problem on the Crystal: In dry years, there may not be enough water for both irrigators and some residential subdivisions.
On Nov. 18, the Gunnison Basin Roundtable gave its unanimous support to the grant application, even though its support was not necessary. Although the Crystal is in the Colorado River basin, its headwaters are in Gunnison County, and so the Gunnison roundtable decided to voice its support.
The feasibility study would look at water demands and options for creating a basinwide backup water supply plan, known as an augmentation plan. The study will look at small storage alternatives, probably off the main stem of the Crystal. Until the study is completed, it’s unclear how much water is needed for a basinwide backup supply.
But some fear that the plan could include dams and reservoirs on the free-flowing Crystal, and they opposed the grant unless storage was off the table.
Pitkin County Commissioner Kelly McNicholas Kury requested two amendments to the grant application: that any reservoir would be off the main stem of the river and would only be located downstream of the Sweet Jessup Canal diversion (about 2 miles downstream of Avalanche Creek) to preserve the possibility of designating 39 miles of the Crystal River as Wild and Scenic.
“We are not going to support this application as it’s currently written,” McNicholas Kury told roundtable members Monday. “The county continues to support Wild and Scenic designation on the Crystal.”
McNicholas Kury and two other roundtable members voted against the funding: recreation representative Ken Ransford and Eagle County representative Chuck Ogliby, who owns the Avalanche Ranch Cabins & Hot Springs in the Crystal River Valley.
The Crystal River Caucus, which doesn’t have a seat on the roundtable, also objected to the grant application and passed a resolution at its Nov. 14 meeting to that effect. In a letter to the roundtable, the caucus said it does not support the grant and urged voting roundtable members to deny the request. The caucus would, however, support a study and augmentation plan that evaluates options other than storage.
But others downplayed the threat of dams, insisting they won’t happen.
“You’re not going to see a dam on the main stem of the Crystal,” said Colorado River District President Dave Merritt. “It’s not going to happen. The river district is not predisposed to dams. There is a need for a small amount of augmentation water up there. We are talking tens of acre-feet, probably.”
No backup supply
During the historic drought of late summer of 2018, the Ella Ditch, which irrigates agricultural land south of Carbondale, placed a call on the river for the first time ever. This means, in theory, that junior-rights holders upstream have to stop taking water so that the Ella Ditch, which has water rights dating to 1885, can receive its full decreed amount.
Most junior-rights holders have what’s known as an augmentation plan, which lets them continue using water during a call by replacing the called-for water with water from another source, such as a reservoir or exchange. The problem on the Crystal is that several residential subdivisions don’t have augmentation plans.
Without an augmentation plan, these entities — which are the town of Carbondale, the Marble Water Company, Chair Mountain Ranch, Crystal River Resort, Crystal View Heights and Seven Oaks Commons — could be fined for every day they are out of priority and could potentially have their water shut off, if there is a call on the river.
Colorado Division of Water Resources Division 5 engineer Alan Martellaro said instead of each subdivision coming up with its own augmentation plan, a basinwide approach makes more sense.
“We think it would save everyone money if we had a reasonable regional solution,” he said. “It looks a lot to us that a call from the Ella Ditch is going to be more common in the future.”
To understand why some groups are opposed to even just a study whether storage is an option, it helps to review the contentious history of water development in the Crystal River Valley.
In 2011, the West Divide district and the Colorado River District abandoned their conditional water rights for nearly 200,000 acre-feet of water storage on the Crystal River after local groups — Crystal River Caucus, Pitkin County and Crystal Valley Environmental Protection Association — opposed the reservoirs tied to the conditional rights. Known as the West Divide project, the now-defunct conditional water rights were tied to a dam on the Crystal just downstream from Redstone, which would have created Osgood Reservoir, and a dam on the Crystal at Placita, which is at the bottom of McClure Pass.
To try to prevent the specter of dams coming back to haunt the Crystal in the future, Pitkin County and other local groups have pushed for a federal designation under the Wild and Scenic River Act of 1968, which requires rivers to be free-flowing. The Colorado River District opposes the designation.
“With our challenging history with both the river district and West Divide … this is why we are very nervous whenever we hear discussion of any dams on the Crystal River,” said Bill Jochems, Redstone resident and member of the Pitkin County Healthy Rivers board.
In the end, the roundtable approved the grant request. A motion to amend the request with a no-storage requirement failed.
“Obviously, storage is not the first choice,” said Ken Neubecker, the roundtable’s environmental representative and Colorado project director for environmental organization American Rivers. “But you have to look at all the options, including storage, or you’re just not being responsible.”
The two conservation districts plan to ask for a $50,000 grant from the Colorado Water Plan grant fund in early 2020 to fund the roughly $100,000 project. West Divide plans to contribute $15,000 and the Colorado River District $10,000.

With the clock ticking on moving its conditional water-storage rights, the city of Aspen is taking steps toward developing a water integrated resource plan, or IRP.
City Council last month approved spending $81,674 to hire Broomfield-based Carollo Engineers as a consultant for the first phase of the IRP. A main goal of the plan will be to decide where to move the city’s conditional water-storage rights after a water court judge in June approved the city’s settlement with opposing parties in two water court cases. The decrees issued by the judge in those cases rule out the possibility of the city building dams or reservoirs on upper Castle or Maroon creeks.
The city has six years to finalize a plan to move the water rights and associated storage to new locations. That and the increasing effects of a hotter, drier climate, which means less water in streams, have the city feeling a sense of urgency when it comes to figuring out its water supply.
“We do have a sense of urgency, but we also recognize we are only going to get one chance to make such a large change to our system,” said Margaret Medellin, Aspen’s utilities resource manager. “We want to do it right.”
Conditional water rights
All 10 parties who settled with the city in water court, one of which was environmental group American Rivers, agreed not to oppose the city’s efforts to change its conditional water-storage rights to different sites.
Instead of flooding two pristine valleys to create reservoirs, the city has identified five other locations to where it could possibly store water. Those sites are the city golf course; the Maroon Creek Club golf course; the city’s Cozy Point open space; the Woody Creek gravel pit; and a 63-acre parcel of land next to the gravel pit, which the city bought in 2018.
“We don’t have any issue with Aspen’s plan to move forward with those conditional water rights,” said Matt Rice, director of American Rivers’ Colorado Basin Program. “That’s a decision for them and local stakeholders to make.”
Carollo Engineers was one of five firms that responded to the city’s summer request for proposals. The more than $81,000 that the City Council approved will pay for Carollo to complete only Phase 1 of the IRP, which will define goals and develop a detailed scope of work. Phase 2 would create the IRP using community input.
“Normally, when we do an IRP, we are looking at what the future looks like in terms of water needs and trying to characterize those and predict them out several decades,” said John Rehring, senior project manager and vice president of Carollo Engineers.
City officials maintain that a lack of reservoir storage is a problem.
Medellin said the lack of water-storage facilities is a big weakness in the city’s water system and that it is controversial to build dams and reservoirs “because every valley up here is beautiful.”
But, Medellin said, climate change may increase the need for water storage.
“We’ve acknowledged these storage rights are very important to the future of Aspen, especially as we start to see climate-change implications,” she said.
Carollo Engineers agrees with that assessment.
“Clearly, the city of Aspen’s system lacks the water storage it needs to reliably meet demands through a range of supply-and-demand conditions even now — before the impacts of climate change have fully taken hold,” the proposal reads.
The issue of storage came to the forefront in the Aspen community in 2012 when news broke that the city was contemplating using its conditional water-storage rights to build dams and reservoirs in Castle and Maroon valleys.
Consultants have come to different conclusions about how much water storage the city actually needs. A 2017 report by Deere and Ault Consultants, which was based on conclusions in a risk analysis by Headwaters Corporation, said Aspen needs 8,500 acre-feet of water storage. But a 2016 study by Wilson Water concluded Aspen does not need any storage.
Two other areas that the IRP will address is the vulnerability of Aspen’s water supply to natural disasters such as 2018’s Lake Christine Fire and last winter’s historic avalanches in Castle and Maroon valleys, as well as how to decrease customers’ demand for water. Even though Aspen has taken steps to reduce the use of water for outdoor irrigation through a landscape ordinance, those gains could be wiped out because in a warmer future, there will be less water flowing in local streams.
“It’s almost like you are playing this game where you, on one hand, lower the level of demand but, on the other side of the equation, climate change is decreasing our supply,” Medellin said.

On a recent snowy morning, aquatic ecologist Bill Miller dipped what’s known as a Hess sampler into the frigid waters of Castle Creek near Aspen.
Miller stirred up the streambed with his hands, funneling the rocks, sediment and leaves — along with macro-invertebrates such as insects and worms — into the collection container.
After putting the organic material into smaller jars and giving each one a squirt of alcohol as a preservative, heferried them to a lab in Fort Collins. Scientists there will count the number and types of bugs in each sample.
“By the different species that are there, you can get a good indication of stream and water quality, and overall ecological function,” Miller said.
Miller’s work is part of a program that will monitor the health of Castle and Maroon creeks, ensuring that Aspen Skiing Co.’s increased water use for snowmaking on Aspen Mountain won’t harm the aquatic environment of the creeks. The stream-monitoring program was set out in September as a condition of Pitkin County’s approval of Skico’s Aspen Mountain Ski Area Master Plan.
“I think the idea of this is we don’t want the snowmaking to cause significant harm to the creeks,” said Andre Wille, chairman of Pitkin County Healthy Rivers board.
Aspen Mountain expansion
As part of its planned expansion, Aspen Mountain will use an additional 57 acre-feet of water per season, bringing the total average snowmaking water use to roughly 257 acre-feet. For context, Wildcat Reservoir, which is visible from the Snowmass Ski Area, holds about 1,100 acre-feet of water.
Skico is expanding its snowmaking for the 2020-21 season on 53 acres near the summit of Aspen Mountain, which will make it easier to have reliable and consistent snow coverage to ensure a Thanksgiving opening. Skico draws its water for snowmaking on Aspen Mountain from the city’s treated municipal supply, which is from Castle and Maroon creeks.
When Skico makes snow in November and December, the upside is there are fewer municipal water users pulling from local streams — outdoor irrigation season is over and holiday crowds have yet to arrive —but snowmaking uses water when natural streamflows are at some of their lowest points of the year.
“We were definitely concerned with the possibility of too much water being taken out in those early months of the winter,” Wille said.
Miller collected samples from above and below the city’s diversion dams on both lower Castle and Maroon creeks. His samples will act as a baseline against which the condition of the streams in future — and perhaps drier — years will be measured.
According to the resolution approving Aspen Mountain’s master plan, if the county’s aquatic ecologist determines, in future years, that the additional water usage is having a negative effect on stream health, the county could limit Skico’s water use to historical levels — about 200 acre-feet a year.
There is another safeguard to keep water in the river, but some say it may not go far enough to ensure stream health.
The Colorado Water Conservation Board, a state agency, holds instream-flow water rights on both Castle and Maroon creeks. And the state has determined that it requires at least 12 cubic feet per second of flowing water to protect the environment to “a reasonable degree” on lower Castle Creek and 14 cfs on lower Maroon Creek.
“We don’t feel it’s advisable to look at what the CWCB may have decreed in the past for a minimum instream flow,” said John Ely, Pitkin County attorney. “That’s not necessarily indicative from a scientific point of view of what is actually needed to maintain a healthy stream.”
That’s why the county hired Miller — who also is the longtime consulting biologist for the city of Aspen — to do its own assessment of stream health.
Ely said stream samples may not need to be taken every year — just in dry years when snowmaking could exacerbate already low flows. He estimated the annual cost of the monitoring program at about $5,000 to $10,000.
Jeff Hanle, Skico’s vice president of communications, said the company is taking steps to increase the efficiency of its on-mountain storage for snowmaking, such as adding two new ponds on Gent’s Ridge, so it won’t need to pull as much water from the city’s supply during the early season.
Although Skico and Pitkin County still need to work out the details of the stream-monitoring program, Hanle said the company is on board with preserving the ecological health of Castle and Maroon creeks.
“We would not make snow if it’s harming the stream, even if it could shorten a season,” he said. “We aren’t going to damage our home.”

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.”

Pitkin County needs to make Basalt’s whitewater park safer. That was the refrain from most of those who spoke at Wednesday night’s public meeting.
“We are not asking for a big change to the kayak park,” said Glenwood Springs resident Elizabeth Bailey. “What we are asking for is a way to get through these monster features.”
Bailey was among those boaters whose rafts were flipped by the lower wave during some of the Roaring Fork River’s highest flows of the season. Bailey, an experienced rafter, said that because the river pushes boats to the right-hand side of the lower wave feature, there needs to be a boat chute to the right, between the hydraulic that forms at high flows and the river bank.
Currently, the only way around the wave is a narrow, hard-to-spot “sneak” on the left side.
The injuries Bailey sustained June 16 sent her to the hospital.
“For that to happen in a manmade park, there needs to be some responsibility,” she said.
Pitkin County Healthy Rivers and Streams hosted Wednesday’s meeting at the Basalt Town Hall to gather public comment about the whitewater park’s two consecutive wave features, which some say became dangerous during this year’s high runoff. The lower of the two waves seemed to present the bigger challenge, even for experienced boaters.
The two structures, built with concrete during the winter of 2016-17, were re-engineered the following winter after complaints that the artificial waves were dangerous. But the low flows of the spring and summer of 2018 did not provide a fair test to see whether the problems had been fixed.
The features are supposed to create fun, recreational play waves at flows between 240 and 1,350 cfs. The river was flowing at about 2,500 cfs the day Bailey was thrown from her boat.
Healthy Rivers Chair Andre Wille said the county’s ultimate goal is to make the best whitewater park they can.
“We are pretty committed to getting it right,” he said.
Quinn Donnelly of Carbondale-based River Restoration, the firm that designed the park, led the public meeting and presented a few options for making the lower wave safer. Crews could lower the “wings” on both features, creating a path around the wave on either side, or a channel could be created around the left side of the wave.
Another idea was to create a “catcher’s mitt” eddy just below the second wave so that boaters who get tossed from their crafts can more easily swim to shore.
But some said creating a way for boaters to get around the waves didn’t go far enough — the waves themselves need to be made safer.
“Here you have two terrifying holes,” Kirk Baker said. Baker is the founder of the Aspen Kayak School and is an expert kayaker. “You should not have to go around. You should be able to go through. … You have to fix the hazard you created.”
Royal Laybourn agreed. Laybourn was also the victim of a flipped boat — he said the wave put him in the hospital.
“You can’t create a hazard and it doesn’t matter what water level it is,” he said. “You’re under a mandate to correct that. … Let’s just make it so any dummy can roll down through there.”
Pitkin County chose the site for the whitewater park, which is just upstream from downtown Basalt, in part because it is just above the Roaring Fork’s confluence with the Fryingpan River. That made it a good place to establish a recreational in-channel diversion water right.
But that part of the river is also steep, Donnelly said, meaning hydraulics will not wash out, but, rather, become bigger as flows increase.
Any new modifications to the wave features that the county and River Restoration decide on will probably come this winter.
“We want it to be as safe as possible,” Donnelly said. “It is a river and there are hazards, but this was put in by people and it’s held to a higher standard.”

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.
Two water-conservation districts are working to find solutions to a long-simmering problem on the Crystal River: In dry years, there may not be enough water for both irrigators and some residential subdivisions.
The Colorado River Water Conservation District and the West Divide Water Conservancy District plan to submit a state grant request for a feasibility study on a basinwide augmentation plan, or backup water supply plan, for the Crystal. The study would look at water demands and augmentation strategies, including the potential for a reservoir in or near the town of Marble.
he historic drought late in the summer of 2018 illustrated some long-acknowledged problems with water rights on the Crystal. In August and again in September, the Ella Ditch, which irrigates agricultural land south of Carbondale, placed a call on the river for the first time ever. This means, in theory, that junior-rights holders upstream have to stop taking water so that the Ella Ditch can receive its full decreed amount.
No back-up water supply
Most junior-rights holders have what’s known as an augmentation plan, which lets them continue using water during a call by replacing the called-for water with water from another source, such as a pond, a reservoir or an exchange.
The problem on the Crystal is that several subdivisions don’t have augmentation plans.
“This hasn’t been a surprise for at least 30 years,” said John Currier, chief engineer for the river district. “This is a well-known problem. The issue has been out there all the time, but the call is potentially becoming more frequent in those kind of dry years.”
The entities that were out of priority in 2018 — and therefore could potentially have water to homes shut off to satisfy a downstream call — include the town of Carbondale, the Marble Water Company, Chair Mountain Ranch, Crystal River Resort, Crystal View Heights and Seven Oaks Commons.
The Colorado Division of Water Resources, which administers the calls, sent these entities letters encouraging them to create an augmentation plan. Otherwise, their water could be shut off or they could be fined for every day they are using water out of priority when there is a future call by a downstream senior-rights holder.
Division 5 Water Engineer Alan Martellaro hopes it won’t come to that. Issuing fines won’t do anyone any good, he said.
“We basically told everybody: As long as we are moving forward and not dragging our feet, we are not going to issue any orders, especially since we are searching for regional answers,” Martellaro said.
West Divide, which is based in Rifle, with its boundary extending up the Crystal River Valley nearly to McClure Pass, sees the situation as an opportunity for basinwide cooperation to find what will probably be a multi-faceted solution. But that will require groups that were once at odds to work together.
“At this point, we are just getting back into this to see what’s feasible, and at this point we want to, and are open to, working with any interested parties up there,” said Bruce Wampler, a West Divide board member.
In 2011, the West Divide district and the Colorado River district abandoned their conditional water rights for nearly 200,000 acre-feet of water storage in the Crystal River drainage after local groups — Crystal River Caucus, Pitkin County Healthy Rivers and Crystal Valley Environmental Protection Association — opposed the reservoirs included in the conditional rights.
At the Gunnison Basin Roundtable meeting in Montrose on Sept. 16, Wendy Ryan, project manager for Colorado River Engineering, an engineering firm that works with West Divide, asked roundtable members for a letter of support for the grant application. (The town of Marble, which could be the site of storage, is in Gunnison County, but not in the Gunnison River basin.) Some roundtable members said they want to see the involvement of environmental groups before they would offer a letter of support.
“It’s going to be a hard nut to crack,” said Gunnison County Commissioner Jonathan Houck, a roundtable member.
As of Thursday, no members of the Pitkin County Healthy Rivers board said they had been informed of the grant application or the augmentation-plan study. The group officially opposes the construction of new storage facilities in the Crystal River watershed.
To get the state money from the Water Supply Reserve Fund, the feasibility study request must be approved first by the Colorado River Basin Roundtable and then the Colorado Water Conservation Board. The request, though not yet finalized, will probably be for roughly $100,000, Currier said.
West Divide introduced the proposal to the CBRT on Monday, and plans on putting forth a formal grant request in November.

“This report sort of drove the message home that (climate change) is here and it’s no longer a conceptual discussion — it’s a pragmatic discussion,” Carbondale Mayor Dan Richardson said. “It was sobering from that perspective.”
According to the report, the average temperature since 2000 has been 2.2 degrees warmer than the 20th-century average. Water year 2018 was more than 4 degrees higher than the 20th-century average and was the warmest recorded in the past 120 years.
Warmer temperatures are bad news for the watershed because they have an overall drying effect, even if precipitation remains constant. According to the report, Roaring Fork River streamflows since 2000 have been about 13% lower than the 20th-century average, due, in part, to warmer temperatures. By 2050, a typical year in the Roaring Fork Valley is projected to be warmer than the hottest years of the 20th century, which means mild drought conditions even during years with average precipitation.
“Just the warming temperatures alone are enough to tell us drought will be a concern in the future and drought conditions are likely to persist for longer,” said WWA managing director Benét Duncan. “What does that mean for the water supply?”
Drought illustrates vulnerability
The summer of 2018’s historic drought illustrated a vulnerability in Carbondale’s water supply that surprised local officials. Senior water-rights holder Ella Ditch, which serves agriculture lands south of Carbondale, placed a call for the first time Aug. 8.
This meant that because there wasn’t enough water in the Crystal for Ella Ditch to divert the amount to which it was legally entitled, junior water-rights holders, including Carbondale, had to reduce their water use — threatening the domestic water supply to roughly 40 homes on the Nettle Creek pipeline.
“We had a situation last summer where we were inches away from having to shut down our water-treatment plant at Nettle Creek because there was a more senior call on the river,” Richardson said. “When you look at the water rights we have on paper, most municipalities feel confident their water portfolio is resilient and can stand the test of time, but that was paper water. And when it comes to wet water, we were pretty vulnerable.”
Carbondale applied for and received an emergency substitute water-supply plan from the state engineer. The emergency plan allowed for a temporary change in water right — from agricultural use to municipal use — so that another irrigation ditch could provide water to the town.
The East Mesa Ditch Co., whose water right is senior to Ella Ditch’s, agreed to loan the town 1 cubic foot per second of water from Sept. 7 to Dec. 7 under the agreement. However, Carbondale had to borrow the water only until Sept. 28, when the call was lifted on Ella Ditch. East Mesa Ditch is located upstream from Ella Ditch. Both are used to irrigate lands farther downstream on the east side of the Crystal River.
The town didn’t pay East Mesa Ditch for the water but paid the company about $5,000 in legal and engineering fees to draw up the water loan agreement, according to Town Manager Jay Harrington.
A wake-up call
Although Carbondale has other sources it can turn to for municipal use, including wells on the Roaring Fork, the summer of 2018 and the VCAPS report were a wake-up call.
“Nettle Creek is a pretty senior right, and we didn’t anticipate it to be called like it was,” Harrington said.
Potential solutions to another Ella Creek call outlined in the report include moving away from Crystal water sources to Roaring Fork sources and providing upstream pumps to the homes on the Nettle Creek pipeline.
“I think (the report) gives one of the clearest pictures of where we are heading and what we need to look at as a municipality as the climate changes,” Harrington said.

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.
On Monday, the city announced that it is the recipient of $186,356, which will go toward establishing “alternative transfer methods” with area farmers. ATMs allow water-right holders to share a portion of their claims without giving them up entirely. The state has a goal to assist in 50,000 acre feet of water transfers through the use of ATMs by 2030.
The program allows creative solutions to water sharing in a way that was not previously accessible, according to Margaret Medellin, city of Aspen’s utilities portfolio manager.
“Traditionally in Colorado water law, if you don’t use your water right you’ll eventually lose it,” Medellin said, “so before this ATM concept came about you would want to use your water rights as much as you can at all times.”
This tactic is counterintuitive to what the state needs from its water holders, though. Colorado’s population growth projections show that the demand for water will increasingly outmatch the supply. By 2050, the state’s population is estimated to reach 10 million — double 2008’s figure — creating a water shortage for about 2.5 million families.
In attempting to preserve its own water rights on Castle and Maroon Creeks, the city found itself headed to state water court with 10 separate opponents last year. It was during those pretrial negotiations that the city decided to partner with two plaintiffs to explore the ATM solution locally.
“This project is one of a few good things that came out of that effort,” Medellin said. “It really is just us as different advocates for different parts of the community coming together to try and get creative.”
Wilderness Workshop and Western Resource Advocates have assisted the city in seeking out partners who would be willing to forfeit claims on diversions at different times. Over the last year, the city has held stakeholder meetings and consulted with experts, but they realized they would need assistance in identifying good partnerships.
“The thing we realized is that there was no clear project up here,” Medellin said.
The state grant allows the city to hire outside consultants who can continue the work of finding water-rights holders who would be willing to temporarily divert their claims to the city in exchange for fees.
Todd Doherty is the president of Western Water Partnership, the consultant who helped the city with the grant application and will continue to work on securing ATM agreements. He has identified 2,800 irrigated acres that use water diverted at or above the city. His team will be reaching out to farmers to explain the program and gauge interest.
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.

Development and climate change are top threats to wildlife habitat and biodiversity, and in the arid west, water supply is a consistent concern for all kinds of life. But ecologists see a simple, natural way for ecosystems to be more resilient: beavers.
When local ecologist Delia Malone walks along the Crystal River in Carbondale, she sees something missing. The footpath she takes runs through an area that used to flood during spring runoff, but with the combination of development and climate change, it doesn’t anymore. Malone said it’s also, in part, because there are no beavers on this stretch of river.
“When we lose beaver, we also lose the wetlands they create, we lose the water storage,” Malone said. “Beaver dams store tremendous amounts of carbon. When beaver dams dry out because the beaver have left, that carbon goes up and is contributing to global warming.”
People have aggressively pushed beavers out of some areas, especially when they damage irrigation systems, flood fields and roads, and cut down trees on people’s property.
The rodents also create natural water storage — even in dry years — and restore wetlands. So Malone wants to bring more of them to high-elevation public lands in the Roaring Fork Valley. She’s working with researchers at the Colorado Natural Heritage Program on a computer model that will indicate suitable habitat for beavers.
“Beaver can be a simple but a really important strategy to remediate the impacts that we’ve caused by changing our climate,” Malone said.
A 2018 survey by Colorado Wildlife Science found that when beavers return to suitable places, the health of the river ecosystem improves. The willows grow faster, there’s more food for other wildlife and there are more songbirds.
A haven at Hallam Lake
Hallam Lake, a 25-acre nature preserve tucked into a hillside behind the Aspen post office, is a haven for diverse forms of life. Water is pooling and dropping gently through several ponds, which are fed year-round by natural springs. Hallam Lake is home to the Aspen Center for Environmental Studies, or ACES, and this beauty is possible because of a family who has been living here for decades.
The lake is full of life. A recent study found 20 mammal species, dozens of insects and more than 150 plant species, including a carnivorous plant called the Lesser Bladderwort and 15 species of lichen.
“This is sort of this unique ecosystem here, because of the spring water, because of the beavers,” Kravitz said.
Beavers have lived under the roots of spruce trees along the banks at Hallam Lake for decades, and they work hard for the local ecosystem.
“They slow down the water, they filter out pollutants, they slow down floods, they keep the water on the land,” Kravitz said. “They have so many benefits, especially in dry places and where water is going to be a concern in the future.”
With climate change driving persistent drought, that means beavers could help out the entire western United States.

Diversions from the Roaring Fork River’s headwaters to the Eastern Slope ceased on Thursday and are expected to be offline until the seasonal runoff slows down, possibly weeks from now.
Bruce Hughes, general manager of the Twin Lakes Reservoir and Canal Co., said that his entity, which controls the diversion of water from the upper Roaring Fork Basin to the Arkansas River Basin, is hitting the maximum amount of Western Slope water it can store in Twin Lakes Reservoir. In addition, water users on the East Slope that typically rely on Roaring Fork flows are able to meet their needs with native Arkansas Basin runoff.
“Legally we cannot take anymore,” Hughes said, adding that “we are still looking at quite a spell” before diversions can resume — possibly two or three weeks.
That means that as much as 550 cubic feet per second of water that is normally diverted through a 4-mile-long tunnel underneath the Continental Divide will stay in the watershed, adding to the already high flows coming down the Roaring Fork.
Add that to the impacts of a historic winter snowpack, which, thanks to a cold and wet spring, is in the top 10 of longest-lasting snowpacks, according to records kept by the Roaring Fork Conservancy.
The Roaring Fork River, measured at Aspen, likely saw its natural seasonal peak early Tuesday morning, when it hit 1,020 cfs. Flows began trending down after that, but they shot back up when the transbasin diversions ceased. Flows through Aspen cracked the 1,000-cfs threshold again on Friday, creating the fourth distinct peak since June 15.
The river will continue to flow naturally until the tunnels are turned back on. The Twin Lakes Reservoir and Canal Co. manages the system that collects water from the Roaring Fork River and from Lost Man, Grizzly, Lincoln, New York, Brooklyn and Tabor creeks, and delivers the water to Grizzly Reservoir. From there it is sent through the 4-mile-long Twin Lakes Tunnel, under the Divide, into Lake Creek and down to Twin Lakes Reservoir, on the east side of Independence Pass and a short distance from the confluence of Lake Creek and the Arkansas River.
There was a bit of an unknown when the Twin Lakes Reservoir and Canal Co. announced earlier in the week that diversions to the Front Range would cease Thursday, resulting in an increase in the water in Lincoln Creek and the Roaring Fork River. The water company’s allotment at Twin Lakes on the other side of the Continental Divide filled Thursday. As a result, an additional 550 cubic feet per second of water started flowing into the Roaring Fork River starting at about 1 p.m. Thursday.
Pitkin County Emergency Manager Valerie MacDonald said higher flows in the Roaring Fork River were evident Friday morning compared with Thursday evening. Twin Lakes officials told her the water levels released into the Roaring Fork wouldn’t exceed 550 cfs. In addition, runoff levels are easing. As a result she doesn’t expect problems with flooding.
The National Weather Service has issued a flood advisory for the Roaring Fork River near Aspen, but only minor lowland flooding is expected.
“This heavy runoff will cause the Roaring Fork River to hover near to above bank full stage into early next week,” the weather service office in Grand Junction said in a notice. Bank full stage is 4.0. Flood stage is 5.0. The river was expected to rise to 4 feet by early morning today, according to the weather service…
The U.S. Bureau of Reclamation decreased releases from Ruedi Reservoir from 917 cfs to approximately 717 cfs on Friday morning. Ruedi Reservoir is expected to fill to capacity today or tonight. And right on cue, inflow to the reservoir is expected to plummet. The forecast by the Colorado Basin River Forecast Center showed in the inflow falling below 900 cfs starting today.
Basalt Police Chief Greg Knot said no problems were reported on the Fryingpan River through Basalt during the period of highest releases…
A flood advisory was canceled Thursday for the Crystal River. The weather service said the river crested at 4.5 feet near Redstone and would continue to fall. Flood stage is 5.0.
