The U.S. Forest Service on Monday approved an application from the cities of Aurora and Colorado Springs for geotechnical drilling in the Homestake Valley, one of the first steps toward building a new dam and reservoir on Homestake Creek.
The approval allows the cities, operating together as Homestake Partners, to drill 10 bore samples up to 150 feet deep and for crews on the ground to collect geophysical data. The goal of the work, which is expected to begin in late summer and last 50 to 60 days, is a “fatal flaw” feasibility study to determine whether the soil and bedrock could support a dam and reservoir.
The project, known as Whitney Reservoir, would be located near the Holy Cross Wilderness Area, which is six miles south of Red Cliff. Various configurations of the project show it holding between 6,850 and 20,000 acre-feet of water. The area is home to a rare kind of groundwater-fed wetland with peat soils known as a fen.
Eagle-Holy Cross District Ranger Leanne Veldhuis approved the project despite receiving a total of 775 comments on the drilling proposal during the scoping period. According to the public scoping comment summary, the most common topics commenters had concerns about included the potential loss of wilderness, the destruction of fens and wetlands, impacts to water quality and disturbance to wildlife.
But just 80 letters — about 10% — were individual comments that the Forest Service considered substantive and specific to the geotechnical investigation. Most comments were form-letter templates from organizations such as Carbondale-based conservation group Wilderness Workshop or pertained to concerns about the Whitney Reservoir project as a whole, not the geotechnical drilling.
“A lot of the public comments were pertaining to a reservoir, and the proposal is not for a reservoir; it’s for just those 10 geotechnical bore holes,” Veldhuis said.
Many commenters also said the level of analysis under the National Environmental Policy Act wasn’t appropriate and questioned why the proposal was granted a categorical exclusion, rather than undergoing the more rigorous Environmental Analysis typical of big projects on Forest Service land. Veldhuis said the geotechnical investigation, a common occurrence on public lands, didn’t rise to the level of an EA; that could come later with any reservoir proposal.
“If the future holds any additional sort of proposal, then that would trigger a brand-new analysis with additional rounds of public comments,” she said. “Any future proposals for anything more would undergo an even bigger environmental analysis than this underwent.”
The proposed Whitney Reservoir would pump water from lower Homestake Creek back to Homestake Reservoir, about five miles upstream. Then it would go through a tunnel under the Continental Divide to Turquoise Reservoir, near Leadville, and then to the cities of Aurora and Colorado Springs. The idea of expanding the intrastate plumbing system to take more water from the headwaters of the Colorado River over to thirsty and growing Front Range cities doesn’t sit well with many people and organizations.
Wilderness Workshop issued a news release saying it would oppose the reservoir project every step of the way. The organization also launched an online petition Monday to rally opposers, which had already garnered more than 200 signatures as of Monday evening.
“We would like to see the Forest Service change course,” said Juli Slivka, Wilderness Workshop’s conservation director. The decision was discouraging, she said, but Wilderness Workshop will continue pressuring the federal agency. “The idea of moving water from the Western Slope to the Front Range is not very appreciated out here.”
Eagle River MOU
But Front Range municipalities are not the only ones set to benefit from a new water-storage project. The Eagle River Memorandum of Understanding lays out a plan for both Front Range and Western Slope entities to develop water in the upper Eagle River basin. The agreement, signed in 1998, provides 20,000 acre-feet of water a year to Homestake Partners and 10,000 acre-feet a year to the Colorado River Water Conservation District, the Eagle River Water and Sanitation District, Upper Eagle Regional Water Authority and Vail Resorts, known collectively in the MOU as the “Reservoir Company.”
The Reservoir Company is not an applicant in the drilling proposal and none of the Western Slope entities that are parties to the MOU submitted comments on the drilling proposal.
Diane Johnson, communications and public affairs manager for the Eagle River Water and Sanitation District, said the water provider supports Homestake Partners’ right to pursue an application for their water.
“We trust the permitting process to bring all impacts and benefits to light for the community to consider and weigh in total,” Johnson said in an email.
The Forest Service also determined that impacts to wetlands from the drilling are negligible. Homestake Partners plans to place temporary mats across wetland areas to protect vegetation and soils from the people and machinery crossing Homestake Creek. In a June letter, a representative from the U.S. Army Corps of Engineers said the work did not require a permit from that agency.
The Forest Service also conducted a biological assessment and found that the drilling would not impact endangered Canada lynx.
