WESTMINSTER — 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.
