The Saskatchewan River (Cree: kisiskāciwani-sīpiy, meaning "swift flowing river") is a major Canadian river. It spans about 550 kilometers (340 miles) from the confluence of the North and South Saskatchewan Rivers near Prince Albert, Saskatchewan, to Lake Winnipeg. Flowing east through Saskatchewan and Manitoba, it empties into Lake Winnipeg. Its watershed covers much of Canada’s prairie regions, extending to the Rocky Mountains in Alberta and northwestern Montana in the U.S. With its tributaries, the river stretches 1,939 kilometers (1,205 miles) to the Bow River’s headwaters in Alberta. It is formed by the North and South Saskatchewan Rivers, originating from Alberta's glaciers. The St. Mary River, from Glacier National Park, also feeds into the Saskatchewan River via its south fork. The combined flow moves east-northeast through Codette Lake, created by the Francois Finlay Dam, then into Tobin Lake, formed by the E.B. Campbell Dam. It continues northeast through marshes, joined by the Torch and Mossy Rivers. It then flows east through Manitoba, joining the Carrot and Pasquia Rivers at The Pas. Southeast of The Pas, it forms a delta on Cedar Lake’s northwest side before flowing into Lake Winnipeg’s northwest shore. Lake Winnipeg's waters eventually drain into Hudson Bay via the Nelson River. The Saskatchewan River’s name reflects its Cree origins, highlighting its role as a vital transportation route for First Nations and early European trappers.
