Aurora, Colorado Springs move toward building additional Homestake reservoir — The Aurora Sentinel

From The Aurora Sentinel (Grant Stringer):

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.

Aspen Journalism first reported the early step to build the reservoir.

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.

The two partners in the transmountain Homestake project have applied to the U.S. Forest Service to drill for soils testing at four potential dam sites.

The Aspen news agency also reported the partners must obtain congressional and presidential approvals to adjust the Holy Cross Wilderness boundary to accommodate a dam.

If the reservoir is built, water would be pumped through a tunnel under the Continental Divide to Turquoise Reservoir at Leadville and on to the two cities.
