Lake Sakakawea

Lake Sakakawea, McLean County, North Dakota

Lake Sakakawea, named after the Shoshone-Hidatsa woman who accompanied the Lewis and Clark Expedition, is a vast reservoir in North Dakota, United States. Formed by the impoundment of the Missouri River by Garrison Dam, it stands as one of the largest man-made lakes in the United States, both in area and volume.

Geography and Hydrology

Located at coordinates 47.50°N 101.41°W, Lake Sakakawea stretches for 178 miles and encompasses a surface area of 307,000 acres. The lake’s maximum depth reaches 180 feet near the dam. It spans across several North Dakota counties, including Dunn, McKenzie, McLean, Mercer, Mountrail, and Williams. The lake’s width varies, averaging 2–3 miles, with a maximum width of 14 miles at Van Hook Arm.

History

Lake Sakakawea’s creation is linked to the construction of Garrison Dam, a key component of the Pick–Sloan Missouri Basin Program, aimed at flood control, hydroelectric power generation, navigation, and irrigation. Completed in 1956, the dam transformed the landscape, submerging the original settlements of the Fort Berthold Indian Reservation and leading to the formation of new communities.

Displacement of Native Communities

The reservoir’s formation led to the displacement of residents from villages like Van Hook and (Old) Sanish. They founded new settlements including New Town, White Shield, and Mandaree. Despite some areas of Van Hook never being submerged, residents were forced to evacuate due to poor planning by the U.S. Army Corps of Engineers. Today, Van Hook thrives as a recreational area.

Recreation

Lake Sakakawea serves as a regional hub for outdoor activities. It is encircled by numerous public recreation areas, parks, and wildlife management zones, overseen by various agencies. The lake is a popular destination for fishing, camping, boating, hiking, and other water-based recreational activities. Lake Sakakawea State Park, adjacent to Garrison Dam, is a noteworthy attraction, hosting the western terminus of the North Country National Scenic Trail.

Environmental Importance
