Oahe Dam is located near Pierre, S.D. at River Mile 1,072.3. The first of the power house’s seven 89,500-kilovolt generators was put into operation in March 1962.  On August 17, 1962, President John F. Kennedy came to the dam and officially dedicated the two generators.  The final generator went into operation in June 1963, completing the $340-million Oahe project.  By 1966, Oahe Dam was generating over 2 billion kilowatt-hours of electricity annually.

Lake Oahe is surrounded by mixed grass prairie with trees growing down to the shore in occasional steep draws.

Oahe Dam takes its name from the Oahe Mission established among the Lakota Sioux people in 1874, about eight miles upstream from the present site of the dam. The word "Oahe," roughly translated, means "a foundation" or "a place to stand on."

Collapse All Expand All

The Lakota Sioux were not the first people in the area now called "the land of the Sioux." The Lakotas displaced people of the Arikara tribe, whose earth lodge villages lined the bluffs along the Missouri River in the 18th century. Traces of the fortresses that guarded their villages still remain.

Present day residents include the Cheyenne River Sioux and the Standing Rock Sioux Tribes, which occupy a majority of land on the west side of Lake Oahe.

Significant historical sites surround Lake Oahe, including the Fort Manuel Trading Post where Sacajawea, the Shoshone Indian woman who served as a guide for Lewis and Clark, is said to be buried.

The grave site of the Lakota Sioux Chief Sitting Bull is also nearby, as is the old military post of Fort Sully.

People travel from all over to participate in recreational activities on the 461,000 acres of land and water that comprise the project.

Guests are encouraged to have fun and are reminded that care should be taken to preserve the lands and waters for future visitors. There are 51 recreation areas around the reservoir including 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.

The story of Oahe focuses on people - from the early Native American tribes, to the fur traders and pioneers, to those who manage, operate and use the facility today. All play an important role in shaping and developing this region.

Lake Oahe's 2,250 mile shoreline offers a myriad of opportunities to outdoor recreationists. Swimmers, sightseers, campers and picnickers alike have their choice of outdoor activities. More than 1.5 million visitors enjoy Lake Oahe's recreation facilities each year.

Campers may choose between fully developed campsites with electrical hookups, trailer dump stations and comfort stations and more primitive sites with little or no amenitites. The day-use areas have picnic shelters, tables, grills, drinking water, comfort stations and playground equipment.

Anglers come to Lake Oahe for the great variety of sport fish, especially walleye and Chinook salmon. Other fish species include channel catfish, northern pike, whitebass, small mouth bass, sauger, trout, perch, blue gill and crappie. Concrete boat launching ramps are available at many locations on the lake.

Many of the public lands around the lakes and rivers, except for developed recreation areas, are open to hunting and offer a great place for sportsmen to hunt pheasants, grouse, partridge, turkey, waterfowl and deer. Wildlife management areas around lake and other areas may allow trapping/snaring please refer to the regulations that are established and enforced by the State of North Dakota.  The Corps of Engineers has certain project restrictions for areas it directly operates (buildings, recreation, and day use areas) for hunting, trapping, and snaring.

Highways 1804 and 1806 pass by most of Oahe’s recreation areas from Bismarck, N.D. and Pierre, S.D.
