Garrison Dam

Garrison Dam One of six dams on the Missouri River, Garrison Dam was responsible for the creation of Lake Sakakawea. Lake Sakakawea is the third largest man-made lake in the United States.

Construction of the Garrison Dam ran from 1947-1954 at a cost of $300 million. The dam is 210 feet high and two-and-a-half miles long. Its embankment consists of 66.5 million yards of rolled earth fill.

Garrison Dam is the fifth largest dam in the United States, with five hydropower generating units in the powerhouse. The dam produces enough electricity to supply the electrical needs of a city the size of Omaha, Nebraska, and its 350,000 people.
