Protocol boosts water flow to the Colorado River
Written bySummit Daily News
In this year of historically low runoff, the Colorado River District, Denver Water and the Bureau of Reclamation are cooperating to add flows to the Colorado River through the Shoshone Outage Protocol for the benefit of fish, rafting and crop irrigation along the entire stretch of the mainstem from Parshall in Grand County to Grand Junction in Mesa County.
According to a press release Thursday from the Colorado River District, the extra water is the result of the Shoshone Outage Protocol, a part of the Colorado River Cooperative Agreement hammered out over the last six years by 42 West Slope entities and Denver Water.
The three reservoir operators are increasing river flows by about 450 cubic feet a second (cfs) through releases from Wolford Mountain Reservoir, Williams Fork Reservoir and Green Mountain Reservoir, respectively. Through the weekend and early next week, flows in Glenwood Canyon should hover around 1,100 cfs, to improve rafting and to aid farmers and ranchers in the Grand Valley, helping to boost flows that are too low. The 71-year average of flows for this time of the year in Glenwood Canyon is more than 6,000 cfs.
The Protocol is designed to add water to the Colorado River when the Shoshone Hydro Plant in Glenwood Canyon is down for maintenance and not using its senior water right, which normally would have the river flowing at about 1,250 cfs through the canyon, absent the usual runoff flows. The Protocol is taking place even though all the parties have yet to sign the agreement.VIEW ORIGINAL ARTICLE
