Dworshak Dam discharge flows decrease to allow for maintenance

Discharge flows from Dworshak Dam were reduced Thursday to perform maintenance work, and lower flows are expected later this month.

According to the U.S. Army Corps of Engineers, flows on Thursday dropped from 9,800 cubic feet per second to 4,400 cfs as crews take the dam’s hydroelectric generator unit number 3 out of service and perform scheduled maintenance and testing through May 23rd. Generator unit 2 will also be taken out of service next Monday through Friday for maintenance, and discharge flows will drop to about 2,400 cfs.

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.

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. (U.S. Army Corps of Engineers)
