Lake Sakakawea, upper left, is a reservoir in the Missouri River basin in central North Dakota. It is the third largest man-made lake in the United States, after Lake Mead and Lake Powell. Here it is covered with snow and ice, thus appearing white.

It is located about 80 km (50 mi) from Bismarck, North Dakota; the distance by the river is about 120 km (75 mi). The lake averages between 2 and 3 miles (3–5 km) in width and is 14 miles (21 km) wide at its widest point (Van Hook arm). Lake Sakakawea marks the maximum southwest extent of glaciation during the ice age.

The reservoir was created with the completion of Garrison Dam in 1956, the second (and largest) of six main-stem dams on the Missouri River built and managed by the U.S. Army Corps of Engineers for flood control, hydroelectric power, navigation and irrigation.

The creation of the lake displaced members of the Fort Berthold Indian Reservation from the cities of Van Hook and (Old) Sanish, forcing the creation of New Town. A third reservation town, Elbowoods was also lost to the lake.

Lake Oahe and Missouri River, South Dakota, USA - November 27th, 2008

The river snaking its way across this image of part of South Dakota, USA is the Missouri River. The lower segments reveal some sediments, while the wider navy blue parts actually constitute Lake Oahe.

The rest of the area seems primarily used for agriculture. To the left, we can see a white patch of snow covering some fields.

Lake Oahe is the 4th largest man-made reservoir in the United States. It stretches 231 miles (372 km) up the course of the Missouri to Bismarck, North Dakota.

Lake Oahe was created by the Oahe Dam, a large man-made dam along the Missouri River, just north of Pierre, South Dakota in the United States.

The dam’s powerplant provides electricity for much of the north-central United States. The project provides flood control, electric power, irrigation, and navigation benefits, estimated by the Corps of Engineers at $150,000,000 per year.

However, the construment of the dam also caused much displacement of the American Indian population, as the Cheyenne River Indian Reservation and Standing Rock Reservation lost huge parcels of land, including much of their prime agricultural acreage.
