Dworshak Dam releases are increasing from 3,200 cubic feet per second to 10,000 cfs by Sunday for flow augmentation.
According to the U.S. Army Corps of Engineers, as river temperatures increase in the summer months, cooling water from Dworshak Reservoir is released to increase fish survival by moderating river temperatures and flows in the Snake River. It’s referred to as flow augmentation.
Each day through Sunday, releases will increase by approximately 2,000 cubic feet per second per day to a target of 10,000 cfs. Releases will be monitored to meet downstream temperature requirements as needed throughout the remainder of summer.
Dworshak Reservoir is currently at its full pool of 1,600 feet. As releases increase for flow augmentation, the reservoir elevation will begin a steady drop. The reservoir will be approximately 5 to 10 feet below full pool through the Fourth of July weekend.
For safety, the public is advised to be aware of the danger associated with fluctuating river flows and elevations. Caution should be used near riverbanks. Boaters, anglers and other people using waterways both in Dworshak Reservoir and below the dam on the Clearwater River are advised to be alert to changes in water elevation and volume of flow. Additionally, docks may be out of place at boat ramps which may impede the corps’ ability to respond.
