Lake Traverse

BW

The Lake Traverse is the southernmost waters within the catchment area of ​​Hudson Bay. It is located along the border between the U.S. states of Minnesota and South Dakota. A low continental divide separates the land on the south shore of Lake Traverse from the Little Minnesota River, which is part of the Mississippi River system and less than two kilometers away from the lake flows through the town of Browns Valley.

During the last Ice Age, the southern end of Lake Traverse was the southern drainage of glacial Lake Agassiz through the so-called Traverse Gap in the lakebed River Warren; which formed the valley through which flows at the present time the Minnesota River.

Lake Traverse is among others by the Inca Must River, which flows near the dam, which was built by the United States Army Corps of Engineers to regulate the runoff and thus the level of the lake. The only outflow is at the north end of the Bois de Sioux River, a tributary of the Red River of the North.
