�� Lake Traverse

Lake Traverse is an 11,200-acre (4,500 ha) lake along the border between the U.S. states of Minnesota and South Dakota, and is the southernmost body of water in the Hudson Bay watershed of North America. Lake Traverse is drained at its north end by the northward-flowing Bois de Sioux River, a tributary of the Red River of the North. A U.S. Army Corps of Engineers dam at the outflow regulates the lake's level. The Mustinka River flows into the lake just above the dam.
