Reindeer Lake, 6650 km2, elev 337 m, max length 233 km, located on the border between northeastern Saskatchewan and northwestern Manitoba, is the second-largest lake in Saskatchewan and ninth largest in Canada. It has a heavily indented shoreline and contains numerous small islands. On its E shore is the community of Kinoosao, at its N end Brochet, Man, and at its S end, Southend, Sask. It drains mainly to the S, via the Reindeer R and a controlled weir, to the CHURCHILL R and thence E to Hudson Bay. Fishing is an important industry in the area, and sportfishermen are drawn by its clear and deep waters. The name of the lake appears to be a translation of the Algonquian name.
