EncyclopediaThe Dalles DamThe Dalles Dam, 260 ft (79 m) high and 8,875 ft (2,705 m) long, on the Columbia River between Oregon and Wash., NE of The Dalles, Oreg.; built 1952–57 by the U.S. Corps of Engineers. The dam, a major link in the development of the Columbia basin, provides hydroelectric power and improves navigation. Located at the head of the slackwater pool created by Bonneville Dam, it impounds a reservoir that provides ship passage 25 mi (40 km) upstream to John Day Dam. Fishways permit salmon and other migratory fish to pass the dam. The Columbia Electronic Encyclopedia, 6th ed. Copyright © 2007, Columbia University Press. All rights reserved.
