Fish Passage Improvements Result in Increased Survival by Staff International Water Power & Dam Construction, April 23, 2013

Recent tests have shown fish passage improvements at all eight federal dams on the lower Columbia and Snake rivers have dramatically increased survival rates for juvenile salmon and steelhead listed under the Endangered Species Act, the Bonneville Power Administration (BPA) said in a statement on its website.

The Bureau of Reclamation, the U.S. Army Corps of Engineers and BPA collaborate on implementing these improvements at the federal hydropower projects.

As a result, fish survival has climbed to more than 96% at some dams, meeting or exceeding federal performance standards.

BPA ratepayers are a primary funding source for the fish passage work that is one part of a larger effort to protect salmon and steelhead survival at all phases of their lifecycle.

The dams involved in the project are: Bonneville, The Dalles, John Day, McNary, Ice Harbour, Lower Monumental, Little Goose and Lower Granite.
