Bureau of Reclamation officials plan to increase water releases from Flaming Gorge Reservoir in northeastern Utah beginning Wednesday.
Increasing the flow from an average of about 820 cubic feet per second (cfs) to 4,600 cfs is aimed at helping the recovery of an endangered fish species by raising the water level to reach the fish's nursery habitat in the Green River's floodplains.
The flows, which could last up to 10 days, are part of an experimental program being conducted by the Bureau of Reclamation, the U.S. Fish and Wildlife Service and the Upper Colorado River Endangered Fish Recovery Program.
The projected peak at Jensen with the flows from the Green and Yampa rivers is expected at about 12,000 cfs.
The world-class trout fishery on the Green River below the dam also benefits from the increased flows, but fishing can be more difficult than what anglers expect when the water is high.
All users of the Green River should use caution in the higher water.
