17-030 Dworshak Dam discharge flows to decrease Saturday night, then increase on Monday - Flow decrease and increase to help reduce flooding impacts and give hatcheries an opportunity to release juvenile fish smolts

AHSAHKA, Idaho – To help reduce downstream flooding impacts, and to give fish hatcheries an opportunity to release juvenile fish smolts, Dworshak Dam discharge flows are planned to be reduced from the current 12,500 cubic feet per second (cfs) to 7,500 cfs beginning at midnight on Saturday, March 18, according to U.S. Army Corps of Engineers officials. At noon on Monday, March 20, flows are planned to begin increasing 2,000 cfs per hour until flows reach 25,000 cfs at about 10 p.m. Monday night. The Saturday night flow reduction will lower the downstream water surface elevation in the Clearwater River by about a half foot. The reduced flows on Sunday and Monday will reduce the forecasted peak flow on the Clearwater River to minimize local flood impacts in Ahsahka, Idaho and Spalding Idaho. The flow increase on Monday afternoon and evening will increase the river surface elevation about one foot. The increase will result in high water levels and very high velocities in the North Fork Clearwater River.
