The Saskatchewan River Basin

Canada's Watersheds

The South Saskatchewan River is formed where the Oldman and Bow Rivers come together near Grassy Lake, AB. The Red Deer River later joins the South Saskatchewan River near Empress, AB. The North and South Saskatchewan Rivers join at Saskatchewan River Forks and become the Saskatchewan River. The respective watersheds of each of these rivers form the larger Saskatchewan River Basin. The South Saskatchewan River watershed is also called the South Saskatchewan River Sub-Basin.

Nelson River Watershed

The Saskatchewan River Basin drains into Lake Winnipeg in Manitoba, making part of the Lake Winnipeg Basin. From here, the Nelson River flows from the north of Lake Winnipeg into the Hudson Bay. Overall, this is a journey of 1,392 kilometers from the headwaters.
