Around 30 steelhead found dead near Idaho’s Dworshak Dam

KUOW

The Army Corps of Engineers is investigating whether the start-up of Dworshak Dam’s turbines are responsible for the deaths of around 30 steelhead, according to a press release from the Army Corps.

The U.S. Army Corps of Engineers found the dead fish in late December after Idaho Fish and Game reported sightings of numerous dead steelhead on the North Fork of the Clearwater River, which joins the Snake River near the Idaho-Washington border.

After a preliminary investigation, according to the Army Corps, operators followed all turbine start-up procedures, including the use of compressed air to help lower the water level below the turbine blades.

The goal of these procedures is to greatly reduce fish mortalities. However, there are still risks to fish, according to the Army Corps.
