Blue Mesa Reservoir (CO) Set To Fall To 23% Of Capacity; Emergency Releases Shut Down Marinas
As of Sept. 1, the reservoir was 37% full, which is about 68 feet down from a full reservoir, and a ring of muddy shoreline was growing/ n an effort to prop up water levels at the declining Lake Powell, federal water managers are negatively impacting recreation on Colorados biggest man-made lake.
Thats the message from Colorado water managers and marina operators at Blue Mesa Reservoir in Gunnison County. On Aug. 1, the Bureau of Reclamation, which operates the reservoir, began emergency releases. By the time the releases are finished the first week of October, Blue Mesa is projected to fall to its second-lowest level ever, just 215,000 acre-feet, or 22.8% of its 941,000-acre-foot capacity. As of Sept. 1, the reservoir was 37% full, which is about 68 feet down from a full reservoir, and a ring of muddy shoreline was growing. Parking lots and boat slips sat empty, and Pappys Restaurant was closed for the season. The dwindling water levels are first impacting Iola, the easternmost of Blue Mesas three basins. Iola is where the Gunnison River now cuts through a field of mud.
EDIT
The Bureau announced July 16 that it would begin emergency releases through early October from three Upper Basin reservoirs: 20,000 acre-feet from Navajo, on the San Juan River; 125,000 acre-feet from Flaming Gorge, on the Green River; and 36,000 acre-feet from Blue Mesa, on the Gunnison River. The goal of the releases is to prop up water levels at Lake Powell to preserve the ability to make hydropower at Glen Canyon Dam. The 181,000 acre-feet from the three upstream reservoirs is expected to boost levels at Powell by about 3 feet. The three reservoirs are part of the Colorado River Storage Project, and their primary purpose is to control the flows of the Colorado River; flatwater recreation has always been incidental. But the releases at Blue Mesa illustrate the risks of building an outdoor-recreation economy around a highly engineered river system that is now beginning to falter amid a climate change-fueled drought.
EDIT
Last month at Colorado Water Congress summer conference a gathering of water managers, researchers and legislators in Steamboat Springs Rebecca Mitchell, CWCBs executive director and the states representative to the UCRC, told the audience that the impacts of ending the boating season early at Blue Mesa trickle down to all Coloradans. That means dollars in Colorado. That is who we are in Colorado, she said. Its definitely had an impact in that local community when we talk about the recreation. That is heavy.
EDIT
Ed. - That means dollars in Colorado. That is who we are in Colorado, she said. Thanks for clearing that up for us, Rebecca.
