FromThe Chaffee County Times (Max R. Smith) via The Leadville Herald:
In the mid-1960s, a partnership between the cities of Colorado Springs and Aurora installed a diversion dam in the Arkansas River south of Granite near Clear Creek Reservoir as part of a pipeline system bringing water from the western slope of the Continental Divide to the Front Range.
The presence of the diversion dam caused that portion of the river to be non-navigable, requiring portaging of one’s raft or kayak.
By the end of this year, however, Colorado Springs Utilities is on schedule to complete a three-year project to build a new river diversion that will allow boaters to float right through, meaning that the 2020 rafting season will be the first in over 50 years in which the entirety of the Arkansas can be travelled without portage.
“We’ll see how the snow treats us over the next couple weeks, but we’re really down to some final boulder work in the river and general site cleanup at this point,” said CSU project manager Brian McCormick.
The intake that pumped water out of the Arkansas (which, legally speaking, comes from the Eagle River Basin as part of the Homestake Project), destined for Aurora and Colorado Springs, “as with anything in the river for 50-plus years, it took some wear and tear,” McCormick said. “By about the mid-2000s, the cities recognized we needed to rehabilitate this structure to keep it as a reliable facility and ensure safety of the river users.”
Construction on the new $9.1 million diversion project began in 2016 after a number of years of planning, budgeting, and engineering. Support for the project included $1.2 million in grant funding from the Arkansas Headwaters Recreation Area, Colorado Parks and Wildlife and the Colorado Water Conservation Board…
Significant to water consumers in Colorado Springs and Aurora, the project utilizes a new intake and piping structure to send water to the Otero pump station, he said.
Significant to boaters is a chute constructed of boulders and mortar with six two-foot drops that will allow them to pass the intake facility without exiting the river. McCormick said that CSU put the call out to members of Colorado’s river recreation community to participate in a trial run down the chute in November, testing the Arkansas’s newest whitewater feature…
Significant to the scaled, Omega-3 rich denizens of the Arkansas who swim upstream to spawn every year, the new diversion also features a fish ladder: a sequence of weirs and pools that give brown and rainbow trout a route to move up the river to their spawning grounds.
One morning last month, Brad Johnson arrived at a patch of rippling yellow grasses alongside U.S. 24, a few miles south of Leadville in the upper Arkansas River valley. Sandwiched among a cluster of abandoned ranch buildings, a string of power lines and a small pond, it is an unassuming place — except, of course, for its views of 14,000-foot peaks rising across the valley.
But appearances can be deceiving. The rather ordinary-looking property was a fen, which is a groundwater-fed wetland filled with organic “peat” soils that began forming during the last ice age and that give fens their springy feel.
“It’s like walking on a sponge,” Johnson said, marching across the marshy ground, stopping every now and then to point out a rare sedge or grass species.
Johnson was visiting the fen to record groundwater measurements before winter sets in. As the lead scientist for the Rocky Mountain Fen Research Project, Johnson is part of an effort spearheaded and paid for by Aurora Water and the Board of Water Works of Pueblo to study new ways to restore fens.
The research could help facilitate future water development in Colorado, such as the potential Whitney Reservoir project, part of a 20-year water-development plan from Aurora Water and Colorado Springs Utilities for the upper Eagle River watershed. The utilities, working together as Homestake Partners, are looking at building the reservoir in the Homestake Creek valley, south of Minturn, in an area that probably contains fens, which could hinder the project.
Aurora and Colorado Springs are working together on the reservoir project, and Aurora and Pueblo are funding the fens research. Although the Whitney project is not directly tied to the fen project, if the research efforts are successful, they could help Aurora and Colorado Springs secure a permit approval for the reservoir — and maybe alter the fate of an ecosystem.
If you’ve walked through Colorado’s high country, chances are you’ve walked by a fen, which are among the state’s most biodiverse and fragile environments. To protect fens, the U.S. Fish and Wildlife Service and the Environmental Protection Agency drafted a “fen policy” in 1996. The policy, amended in 1999, determined that fens are irreplaceable resources because their soils take so long to regenerate. “On-site or in-kind replacement of peatlands is not possible,” the policy reads.
Inside the Fish and Wildlife Service, however, a different interpretation emerged. “Irreplaceable” became “unmitigable,” making it difficult or impossible to secure approval for any project that would severely impact fens.
Although Johnson is in favor of fen conservation, the Fish and Wildlife Service’s “unmitigable” interpretation bothered him. Not only was that status not supported by the fen policy itself, he believes saying “no” all the time is not in the best interest of fens.
“My fear is that if we don’t have the means of mitigating our impacts, we’ll just impact them,” he said.
Eventually, Johnson believes, conservationists will have to make some concessions to development. But by researching better mitigation techniques, he hopes he can help preserve fens in the long run.
An organ transplant
For water utilities, fens have been particularly troublesome. Fens like to form in high-alpine valleys, the places best suited for dams and water reservoirs that take water from rivers mostly on the Western Slope and pump it over the mountains to supply the Front Range’s growing population.
But the fen policy has stymied many of the utilities’ plans to develop new water projects. Those defeats helped spur Front Range utilities to start researching new mitigation strategies that would help them comply with environmental regulations — and get around the fen policy.
“They wanted to figure out how to do this right so they could actually permit their projects,” Johnson said.
Through the fen-research project, Aurora and Pueblo saw an opportunity to address the fen policy’s requirement that a project offset unavoidable impacts to a fen by restoring an equivalent amount of fen elsewhere.
Since the fen project began 16 years ago, Aurora and Pueblo have invested $300,000 and $81,500 in the research, respectively. More recently, other funders have joined the effort, including Denver Water, Colorado Springs Utilities at about $10,000 each and the Colorado Water Conservation Board ($100,000).
After a number of fits and starts, Johnson three years ago settled on a design for the research that would test whether it’s ecologically possible to transplant fen soils from one location to another. First, Johnson restored the original groundwater spring at the old Hayden Ranch property. Then, he and a team of helpers removed blocks of soil from another degraded fen site and reassembled them, like an organ transplant, at the “receiver” site, where the restored spring now flows through veinlike cobble bars and sandbars, feeding the transplanted fen.
It’s still too early to know whether the project could eventually serve as a fen-mitigation strategy for a new reservoir, but Johnson is optimistic about the results thus far. In 2017, after just one growing season, he was shocked to discover 67 different plant species growing at the transplanted fen site — compared with just 10 at the donor site. He was thrilled by the news. The data showed that the transplanted fen ecosystem is thriving.
That’s good news for utilities such as Aurora, too.
A week after Johnson visited the Rocky Mountain Fen Project site, Kathy Kitzmann gave a tour of the wetland-filled valley formed by Homestake Creek where Aurora and Colorado Springs are planning to build Whitney Reservoir.
Kitzmann, a water resources principal for Aurora Water, drove down the bumpy, snow-covered road that winds along the valley bottom, pointing to the two creeks that would — along with Homestake Creek and the Eagle River, near Camp Hale — help fill the reservoir. A pump station would send the water upvalley to the existing Homestake Reservoir and then through another series of tunnels to the Front Range.
In the lower part of the valley, Kitzmann stopped at the first of four potential reservoir sites — ranging in size from 6,000 acre-feet to 20,000 acre-feet — that the utilities have identified for the project and the wetlands it would inundate.
“You can sort of see why it wouldn’t be the best, just given the vastness of the wetlands,” Kitzmann said.
Farther along, the valley becomes more canyonlike, with higher rocky walls and fewer wetlands — probably offering a better reservoir site, said Kitzmann, although the permitting agencies won’t know for sure until they complete their initial feasibility studies.
In June, Aurora and Colorado Springs submitted a permit application to the U.S. Forest Service to perform exploratory drilling and other mapping and surveying work, but the agency has not yet approved the permit.
Potential fen impacts are just one of several environmental hurdles facing the project. One of the Whitney alternatives would encroach on the Holy Cross Wilderness. Aurora and Colorado Springs have proposed moving the wilderness boundary, if necessary, to accommodate the reservoir.
It’s also likely that the wetlands in the Homestake Valley contain fens, but until the utilities conduct wetland studies around the proposed reservoir sites next summer, the scope of the impacts remains uncertain.
Environmental groups including Colorado Headwaters, a nonprofit, oppose the Whitney Reservoir project, arguing that it would destroy one of the state’s most valuable wetlands, as well as an important habitat for wildlife and rare native plants.
In the meantime, Aurora is hopeful that Johnson’s research might one day help solve some of the environmental problems around new water development. “We are excited about proving that you can restore and rehabilitate fens,” Kitzmann said.
But is a transplanted fen as good as not touching one in the first place?
A Fish and Wildlife Service spokesperson said fens are still designated a “Resource Category 1,” which means that the appropriate type of mitigation is avoidance, or “no loss.”
White River National Forest supervisor Scott Fitzwilliams echoed the spokesperson’s statement, noting that land managers place a high emphasis on protection for fens: “It’s really hard to replace a wetland in these high elevations.”
Johnson, asked whether he was worried that his research into fen mitigation might end up facilitating the kinds of projects that are most damaging to fens. He sighed. “I’m sensitive to that,” he said.
But like it or not, Johnson believes that more impacts to fens are inevitable. As Colorado’s population grows, water utilities will have to build new reservoirs, the state will need new roads and ski resorts will want to expand.
“I can’t argue with whether they should get built,” he said. “I’m just a wetlands guy.”

The Homestake Project is a trans-mountain raw water collection, storage, and delivery system co-owned and operated by the cities of Colorado Springs and Aurora, Colo.
The Homestake Arkansas River Diversion (ARD), between Granite and Buena Vista, Colo., was constructed in 1964 as the original intake for the Otero Pump Station. Water is now primarily withdrawn from Twin Lakes, however the ARD remains an alternate point of diversion. The ARD has deteriorated and requires repair. The ARD was not originally designed as a navigable facility.
Colorado Parks and Wildlife (CPW) manages the Arkansas Headwaters Recreation Area (AHRA) which includes the site of the ARD. CPW expressed interest in partnering with Springs Utilities on a rehabilitation project to include a boat chute for downstream navigation as this location is currently considered the only non-navigable reach of the Arkansas River between Leadville and Canon City, Colo.
The Upper Arkansas River is both one of the most heavily used rivers in the United States for whitewater recreation and is a Gold Medal Trout Fishery. The river is managed to support multiple objectives including water supply and delivery and outdoor recreation.
The cities of Aurora and Colorado Springs are constructing a rehabilitation project that will replace the intake and diversion, provide a boat chute for downstream navigation, and provide upstream fish passage for spawning of brown and rainbow trout. The project also included improving river safety for recreational users and providing whitewater boat portage. User safety was an extremely important design consideration.
A physical model was constructed to test and refine hydraulic elements to optimize performance, maximize user safety and meet design guidelines for recreational whitewater for all three components: boat chute, fish passage and the new intake structure.
The $9 million construction cost of the project is being jointly funded by the cities of Aurora and Colorado Springs. $1.2 million in grants is coming from Colorado Parks and Wildlife and the Colorado Water Conservation Board through grant funding to support the Colorado Water Plan (Water Supply and Demand Gap and Environmental and Recreation Grant Programs). The Pueblo Board of Waterworks is donating the easements necessary to construct and maintain the diversion.
Here’s a report from Jason Blevins writing for The Colorado Sun:
But just below the former riverside mining camp of Granite, where a dilapidated dam built in 1964 has long blemished the Arkansas River’s beauty, rebar jutted from concrete blocks, preventing raft passage and spawning trout battled the steep wall of blasted rocks to reach upstream pools.
“Not a lot of thought went into recreation or fish when this dam was built,” said Ronald Sanchez, an engineer with Colorado Springs Utilities.
A lot of thought is going into fish and recreation now, as water managers in Colorado Springs and Aurora join the Colorado Water Conservation Board, the Pueblo Board of Water Works, Colorado Parks and Wildlife and the Arkansas Headwaters Recreation Area in rebuilding the diversion that directs water to the Front Range.
The $9.1 million project will make the entire river from Leadville to Cañon City navigable for rafts for the first time in at least 55 years.
It’s part of the vast Colorado Springs- and Aurora-owned Homestake Project that brings Eagle River Basin water from the Holy Cross Wilderness to the Arkansas River Basin, through the Homestake, Turquoise and Twin Lakes reservoirs for delivery to the Front Range cities.
The cities started construction of the Arkansas River diversion in July 2018, creating three distinct channels below a rebuilt intake that serves as a backup water diversion to the Otero Pump station downstream of Twin Lakes Dam. Before the Twin Lakes Dam was built in the late 1970s, the diversion was the original intake that collected and directed water to the Otero Pump station for delivery to Aurora and Colorado Springs.
One channel is a fish ladder for spawning brown and rainbow trout. Another channel is a spillway to accommodate flood-level flows like the ones that swelled the Arkansas River this spring. And a third is a series of six drops allowing rafts safe passage.
The project marks a new era of collaboration between the diverse interests on the Arkansas River between Leadville and Cañon City, one of the most recreated stretches of river in the U.S.
“For me the coolest thing about it is that you have these large water utilities in Colorado going above and beyond to do the right thing for the next 50 years,” said Salida-based whitewater park engineer Mike Harvey.
Ten years ago, Harvey helped the Arkansas Headwaters Recreation Area craft a report urging Aurora and Colorado Springs to consider recreation and fish when it came time to rebuild the Granite Dam diversion…
The Arkansas River accounts for more than $74 million of the $177 million in economic impact created by commercial rafting in Colorado. The 102 miles of river in the Upper Arkansas River Valley also ranks among the 322 miles of Colorado waterways that qualify as Gold Medal Fisheries that can yield a dozen large trout per acre. It also supplies a large percentage of water to Colorado Springs and Aurora via the 66-inch pipeline that runs from the Otero Pump Station.
Rebecca Mitchell, the executive director of the Colorado Water Conservation Board, said the project exemplifies the collaboration of the Colorado Water Plan, which gathered perspectives from all types of water users in the state to create a policy roadmap for future water planning across the state.
Colorado Parks and Wildlife and the conservation board provided $1.2 million in funding through Colorado Water Plan grant programs.
Here’s the release from Colorado Springs Utilities:
There is an increasing occurrence of toxic blue-green algae in reservoirs across the United States this year, forcing the limitation of recreational access to the bodies of water for public safety.
In a recent test at Pikeview Reservoir, a popular fishing lake in central Colorado Springs and part of our water system, the bacteria was identified.
While the reservoir is still safe for fishing, as a precautionary meaure, humans and pets are prohibited from entering the water until further notice. Anglers are directed to thoroughly clean fish and discard guts.
We have removed Pikeview as a source for drinking water until the reservoir is determined to be clear of the algae. There are no concerns about this affecting water supply for our community.
Presumptive testing has indicated levels of less than 5 mcg/L.
Sickness including nausea, vomiting, rash, irritated eyes, seizures and breathing problems could occur following exposure to the blue-green algae in the water. Anyone suspicious of exposure with onset of symptoms should contact their doctor or veterinarian. For questions regarding health impacts of exposure, contact the El Paso County Health Department or Colorado Department of Public Health and Environment.
Warming temperatures have contributed to the growth of the bacteria.
The popular fishing lake that lies just south of Garden of the Gods Road tested above acceptable limits for the bacteria the news release read. The water is still safe to fish in, but humans and pets are not allowed. Anglers are asked to clean the fish thoroughly and remove guts, according to the news release.
The reservoir has been removed as a drinking water source, Utilities stated, however there are no concerns about the tainted water affecting the community.
Local officials say damming a creek between Leadville and Minturn — and routing water normally flowing into the Colorado River — is necessary to sate the future thirsts of a city growing on land where water is scarce.
Aurora Water and Colorado Springs Utilities recently applied together for a permit to drill underground near the creek and test where a large Whitney Reservoir would be best situated.
For the dam, the utilities are eyeing four possible locations about six miles southwest of Red Cliff.
But damming Homestake Creek would also require moving the boundary of the Holy Cross Wilderness, affecting ancient, pristine wetlands.
Greg Baker, Aurora Water’s manager of public relations, said the Whitney Reservoir could be built in 25 years if key steps such as test drilling on Forest Service land are approved.
Baker said it’s another creative step to make sure that Aurora doesn’t go dry.
“You don’t leave anything on the table when you’re in Colorado, because most of the water has been appropriated in river basins,” he said.
Baker said the reservoir could eventually hold anywhere from 9,000 acre-feet to 19,000 acre-feet of water. The water would then be pumped near Leadville and travel to the Front Range through tunnels to the South Platte River basin.
Currently, only Aurora and Colorado Springs would benefit, Baker said.
The project is another alliance between Aurora Water and Colorado Springs Utilities. The two cities — the state’s largest behind Denver — are both growing quickly. Baker said the new reservoir could help ensure the taps keep flowing, especially in an era with snowpack decreases that imperil creeks and rivers.
Here’s the release from the Colorado State Forest Service:
Colorado Springs Utilities, the U.S. Forest Service Rocky Mountain Region and Colorado State Forest Service (CSFS) announced their plans to invest $15 million, over a five-year period, in forest and watershed restoration projects. These projects will occur on more than 11,000 acres in Colorado Springs Utilities’ critical watersheds located on the White River and Pike-San Isabel National Forests
Today’s announcement comes as part of a signing event held at the Mesa Conservation Center to kick off the second phase of watershed restoration efforts.
The U.S. Forest Service Rocky Mountain Region and Colorado Springs Utilities have been in partnership since 2013, and together, have reduced the risk of catastrophic wildfire, restored forests impacted by wildfire, and minimized erosion and sedimentation in reservoirs to over 12,000 acres of National Forest System lands.
“We understand the obligation to the nearly 480,000 customers within the Colorado Springs Utilities area and the importance of healthy watersheds. Thus, we place heavy emphasis on partnerships like these, which allow us to keep clean water flowing to our local communities while maintaining resilient and productive forest lands,” Regional Forester, Brian Ferebee stated.
“Our dedication to conservation and natural resource sustainability has been amplified with the inclusion of the Colorado State Forest Service.”
The agreement, which now extends the existing partnership to the CSFS, expands the capacity to implement priority projects, leverage state resources, and balance national, state and local priorities. Since 1987, Colorado Springs Utilities has partnered with the CSFS to manage forests on 13,000-acres in the Pikes Peak Watershed. Their work to protect water quality, improve water yields, and identify and reduce wildfire risk, have dramatically improved forest health.
Together, the partnership promotes an “all lands” approach that addresses watershed and forest health challenges on the National Forest System and neighboring lands.
Forest & watershed health projects
“The destruction of Waldo Canyon required a huge investment from Colorado Springs Utilities to repair damaged water infrastructure and restore severely burned watersheds,” said Earl Wilkinson, Chief Water Services Officer, Colorado Springs Utilities. “Our continued partnership with the U.S. Forest Service and Colorado State Forest Service will enable critical preventative measures to protect our drinking water supply.”
Under the 2019-2023 program, Colorado Springs Utilities will invest $7.5 million in forest and watershed health projects within critical watersheds. This funding will be matched dollar for dollar by the U.S. Forest Service and the CSFS for a total value of approximately $15 million.
Management activities associated with these projects will include forest thinning, prescribed fire, invasive species management, road and trail improvements, and stream improvements.
“Through partnerships like this one, land managers and water providers in Colorado can help ensure clean, reliable water for present and future generations,” said Mike Lester, State Forester and CSFS Director.
Colorado Springs Utilities has a large mountain water system with many reservoirs and other infrastructure located on U.S. Forest Service Land. Forest restoration and wildfire fuels reduction projects will take place within watersheds near Colorado Springs, including the vicinity of Pikes Peak, the headwaters of the Arkansas River, surrounding Homestake Reservoir on the Eagle River, and in the Blue River watersheds.
The projects will reduce the risk of catastrophic wildfires and post-fire sedimentation and erosion upstream of Colorado Springs Utilities’ reservoirs and other water delivery infrastructure.
