Oahe Dam
Dedicated by President John F. Kennedy in 1962, Oahe Dam is one of a chain of six main stem projects in the upper Missouri River Basin. Construction of Oahe Dam began in 1948 and was completed in 1962. The dam measures 9,300 feet in length with a maximum height of 245 feet. Each of the seven turbines generate 112,290 kilowatts of power.

Lake Oahe is the 4th-largest man-made reservoir in the United States. Named for a Lakota council lodge, Lake Oahe extends from Fort Pierre, South Dakota to Bismarck, North Dakota. The lake is 231 miles long, has 2250 miles of shoreline, and has a maximum depth of 205 feet.

There are 51 recreation areas located around the reservoir. They include highly developed campgrounds and day use areas, moderately developed areas, and primitive areas. Recreation opportunities at the lake include camping, picnicking, fishing, hunting, boating, water skiing, swimming, bird-watching, hiking, biking, and photography.
