Corps To Release
AHSAHKA, ID – Be careful where you anchor your boat tonight. The U.S. Army Corps of Engineers is going to release considerably more water out of Dworshak Dam just after midnight tonight. It’s currently flowing at 9,500 cubic feet per second, and they’ll have it increased to 12,500 by early morning.
The change will increase the river level of the Clearwater about 9 inches at Peck, ID.
The increase is an effort to cool the Snake River at Lower Granite Dam. The National Oceanic and Atmospheric Administration requires the Corps to keep the Snake River below 68 degrees to increase the salmon and resident fish survival rate and increase their speed to reach the ocean. This morning the temperature at Lower Granite was 66.8 degrees with hot weather forecast. The water temperature at Dworshak is 43 degrees.
