Locks on Columbia, Snake rivers to close for repairs, maintenance (copy)

The Bonneville Dam on the Columbia River near Cascade Locks, Ore., is one of eight dams that will increase their spills to help salmon and steelhead transit them.

As part of the Columbia River Basin Agreement, the U.S. Army Corps of Engineers will send more water over spillways instead of through turbines during its annual “spring spill” at dams on the lower Snake and Columbia rivers.

The Corps will also expand spills in the fall and early spring.
