What rivers drain into Lake Winnipeg?

Lake Winnipeg is fed by several major rivers that drain a significant portion of the Great Plains. The primary rivers that discharge into the lake include:1

• Saskatchewan River: This major system enters Lake Winnipeg via Cedar Lake at Grand Rapids.12
• Red River of the North: Flowing northward from the United States, this river empties into the southern end of the lake.13
• Winnipeg River: This river flows northwestward from the Lake of the Woods and enters the southeastern end of Lake Winnipeg.14
• Assiniboine River: This river is a tributary of the Red River, which subsequently drains into Lake Winnipeg.53

While the Nelson River is associated with the lake, it is important to note that it serves as the outlet that drains Lake Winnipeg northeastward into Hudson Bay, rather than flowing into the lake itself.15
