19-048 Dworshak Dam discharge flows decrease to 4,400 cfs

Published May 9, 2019


Water discharged from Dworshak Dam and Reservoir was reduced today, Thursday, May 9, from about 9,800 cubic feet per second (cfs) to 4,400 cfs, according to U.S. Army Corps of Engineers reservoir management officials.

The decrease in flows is necessary for Corps maintenance staff to take the dam’s hydroelectric generator unit number 3 out of service and perform scheduled maintenance and testing May 9-23. Generator unit 2 will also be taken out of service May 13-17 for maintenance. During that period, flows will be further reduced to about 2,400 cfs.

The Corps works with regional water managers, other agencies and tribes, and fish managers and hatcheries in joint efforts to keep total dissolved gasses below the Idaho State maximum threshold, when possible.

For safety, the public is advised to be aware of danger associated with fluctuating river flows and elevations. Outflow water is deep, cold and fast, so extreme caution should be used near river banks. 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 up or down in water elevation and volume of flow.
