Corps Moves Into Refill Mode For Dworshak Dam, Cold Water Will Be Needed To Cool Lower Granite Reservoir For Migrating Fish

After a week of increasing outflows at Idaho’s Dworshak Dam to support releases of juvenile salmon from Clearwater River hatcheries, the U.S. Army Corps of Engineers announced last Friday (April 16) that it will now begin to decrease those flows so that it can be assured of refilling the dam’s reservoir.
