Gavins Point Dam

Gavins Point Dam is a large embankment rolled-earth and chalk-fill dam on the Missouri River located in both Nebraska and South Dakota in the Upper Midwest Region of the United States. The dam and hydroelectric power plant were constructed as the Gavins Point Project from 1952 to 1957 by the United States Army Corps of Engineers. The dam creates the 31,400 acre (12,700 ha) Lewis and Clark Lake and is located approximately 4 miles west (6.4 km) (upstream) of Yankton, South Dakota.
