| Bonneville Dam (BAHN-uh-vil), one of the major dams on the Columbia R. where it passes through the Cascade Mts., on state line of Oregon and Wash.; 2,690 ft/820 m long, 197 ft/60 m high. Built (1933–1943) by the U.S. Corps of Engineers; one of the largest hydroelectric projects undertaken under the New Deal. Its reservoir extends c.40 mi/64 km to the Dalles Dam, 1 mi/1.6 km wide. Used for navigation, flood control, and power production. Locks permit barges to pass around the dam. Bonneville Power Administration contracted for power from 5 nuclear plants, to be built by Wash. Public Power Supply System (WPPSS), which were never finished. New larger locks (1994) improve passage of barges. Fish (salmon) passage problems going downstream. |
