Lake Oahe and Partially Frozen Lake Sakakawea, USA

44.8N 100.6W

April 2nd, 2012 Category: Lakes, Rivers

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 - January 4th, 2012

This image shows the Missouri River flowing through the state of South Dakota, USA. It is the longest river in North America and a major waterway of the central United States. Rising in the Rocky Mountains of western Montana, the Missouri flows east and south for 2,341 miles (3,767 km) before entering the Mississippi River north of St. Louis, Missouri. The river takes drainage from a sparsely populated, semi-arid watershed of more than half a million square miles (1,300,000 km2), which includes parts of ten U.S. states and two Canadian provinces.

The particularly wide section of the river in the upper left quadrant is Lake Oahe, a large reservoir behind the 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. Lake Oahe has a length of approximately 231 mi (372 km) and has a shoreline of 2,250 mi (3,620 km).

USA - November 8th, 2010

The long, winding, thick line parallel to the left edge of this image is Lake Oahe, a large reservoir behind Oahe Dam on the Missouri River. The reservoir begins in central South Dakota and continues north into North Dakota in the United States.

In the full image, a second lake can be seen to the north, also on the Missouri River: Lake Sakakawea in North Dakota. Like its neighbor to the south, it is an artificial reservoir, created with the completion of Garrison Dam.

Lakes in Canada and Northern USA, from Lake Winnipeg to Lake Oahe

USA and Canada - September 26th, 2010

Several lakes can be observed, scattered across this image of northern USA and the Canadian province of Manitoba. The large lakes in the upper part are Lake Winnipeg (tan and green in color), Lake Winnipegosis (green, just below the northern part of the former), and Lake Manitoba (bright green, near the southern part of Lake Winnipeg).

To the south, Lake Sakakawea appears as a navy blue lake with a curved shape, near the image center. It is a reservoir in the Missouri River basin in the US state of North Dakota. To its west, also navy blue in color, is the Fort Peck Reservoir in the state of Montana. Near the bottom of the image is Lake Oahe, on the Missouri River in South Dakota.

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

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.
