From The Aurora Sentinel (Grand Stringer):
U.S. Forest Service District Ranger Leanne Veldhuis approved the cities’ plan Monday to drill into the high-alpine Homestake Valley and test whether the underlying geology could support a reservoir diverting water from the Colorado River to the growing municipalities.
It’s an early, key step in the effort to build the new reservoir, which would be called the Whitney Reservoir, in the National Forest about six miles southwest of the town of Red Cliff.
The cities have long held the water rights to build the new reservoir and divert the water, usually destined for the beleaguered Colorado River, to thirsty residents in Aurora and Colorado Springs.
With approval in tow, Aurora and Colorado Springs have the green light to test for several possible reservoir sites in the Homestake Valley.
Greg Baker, Aurora Water’s manager of public relations, told the Sentinel last year the reservoir could be built in about 25 years if the complicated approval process pans out. The new reservoir in the Homestake Valley could hold between 6,850 acre-feet and 20,000 acre-feet of water, according to the Forest Service…
Notably, the project requires environmental impact studies and possibly an act of Congress, according to Baker, to shave up to 500 acres from the popular Holy Cross Wilderness. However, he added that the plan is far from set in stone.
The plan has drawn scrutiny from conservation groups concerned about devastating the ancient wetland habitant that retains water — an increasingly scare commodity in the West. Various endangered fish species would be downriver from the dam.
The Colorado River itself has seen reduced flows in recent decades, in part because of human-induced climate change. Many environmentalists argue that as much water as possible should be left in the river, which multiple states and Mexico rely on…
Baker said in an email that the drilling study is “routine.”
“We value the collaborative process involved in exploring alternatives that minimize environmental impacts, are cost effective, can be permitted by local, state, and federal agencies, and which will meet the water requirements of the project partners,” he said.
As reported by Colorado Public Radio, the project has also run into early opposition from central Colorado and Western Slope communities.
Democratic state Sen. Kerry Donovan represents seven counties that include communities like Aspen and Crested Butte. In a letter opposing the project, Donovan wrote that, “she can’t express how sternly the people in her district dislike water diversion projects to the front range,” according to CPR.

The decision to let the Front Range water utilities move forward in taking more Western Slope water is only one of countless regulatory hurdles for a future Whitney Reservoir, but conservation groups say they are adamantly against any new water transfers to suburban water users across the Continental Divide and will oppose every approval step.
Colorado Headwaters, which opposes any new dams and water transfers, said it expected the approval but remains steadfast against any progress on the project. “We don’t think it will ever be built,” president Jerry Mallett said. “They haven’t done a transmountain diversion in 45 years. Water on the Colorado River is dropping from climate change. We don’t want to lose those natural resources.”
The decision from White River said the approval applies only to drilling 10 test bore holes the utilities applied for, and does not have bearing on any future decisions should the cities pursue the dam north of Camp Hale. The proposed reservoir would hold about 20,000 acre feet…
The cities partnered with Eagle County, the Colorado Water Conservation District, Vail Resorts and other Western Slope water users in 1998 in a deal that gave water rights to Eagle River communities and developed the 3,300 acre-foot Eagle Park Reservoir on the Climax Mine property.
The 1998 Eagle River Memorandum of Understanding included plans for possible reservoirs along Homestake Creek. The agreement — which brought together a diverse group of downstream users as “Homestake Partners” in the Eagle River Joint Use Water Project — also affirmed that no partner could object to a new reservoir plan if it met the memorandum’s agreement to “minimize environmental impacts” and could be permitted by local, state and federal agencies.
The proposed Whitney Reservoir project is not new and “represents our continued pursuit to develop water rights in existence for many years,” Colorado Springs Utilities spokeswoman Jennifer Kemp said.
Kemp said the cities have developed alternatives to building a new reservoir in the Homestake Creek drainage but those other options have not been proposed or discussed publicly. The results of the test boring and geotechnical work will help the two cities vet possible alternatives…
Environmental groups oppose new dams on Homestake in part because they would take water out of tributaries that feed the already-depleted Colorado River. But they are also focused on preserving complex wetlands called “fens” that develop over the long term and support diverse wildlife. They say fens cannot easily be recreated in any mitigation work that utilities traditionally include in dam proposals.
The headwaters group also questions why the Forest Service would encourage any steps when completion of a dam appears impossible. The utility proposals include shrinking the size of the Holy Cross Wilderness Area to create dam access, “which Congress will never approve,” Mallett said.
