AHSAHKA, Idaho – Discharge flows from Dworshak Dam will be decreased starting at 10 a.m. on Friday, April 18, from approximately 20,000 c.f.s. (cubic feet per second) to about 11,000 c.f.s. to balance flood control operations and flows to support spring smolt outmigration, according to U.S. Army Corps of Engineers water-management officials. The decrease to 11,000 c.f.s. should be completed by noon. This discharge rate is planned to last at least through the end of April, but is subject to change. The Corps advises Clearwater River boaters and other people using regulated waterways to always be alert to changes in water elevation and volume of flow.
