Lake Oahe and Partially Frozen Lake Sakakawea, USA

USA - December 23rd, 2011

The Missouri River winds its way across this image of North and South Dakota, USA. Two large reservoirs can be seen along the river’s course: Lake Sakakawea (upper left quadrant) and Lake Oahe (lower right quadrant).

Lake Sakakawea is a reservoir in the Missouri River basin in central North Dakota. It is the third largest man-made lake in the United States, and was created by the Garrison Dam. Here, the western part of the lake appears frozen. Snow can be seen dusting the terrain across the left side of the image as well.

Lake Oahe, on the other hand, is not frozen. It is a large reservoir behind Oahe Dam on the Missouri River beginning in central South Dakota and continuing north into North Dakota in the United States. The lake has an area of 370,000 acres (1,500 km2) and a maximum depth of 205 ft (62 m). By volume, it is the fourth-largest reservoir in the US.

USA - December 26th, 2011

What appears as a very wide section of the Missouri River in central South Dakota, USA, is the Lake Sharpe reservoir behind Big Bend Dam. The lake has an area of 56,884 acres (230.20 km2) and a maximum depth of 78 ft (24 m). Lake Sharpe is approximately 80 mi (130 km) long, with a shoreline of 200 mi (320 km).

The lake extends up the course of the Missouri River to Oahe Dam and Lake Oahe, partially visible through the clouds in the full image Both the Big Bend Dam and the Oahe Dam were built for power generation and flood control.

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.
