Geography
Reindeer Lake has a heavily indented shoreline and contains numerous small islands. On its eastern shore is the community of Kinoosao, at its northern end Brochet, Manitoba, and at its southern end, Southend, Saskatchewan. It drains mainly to the south, via the Reindeer River and a controlled weir, to the Churchill River and then east to Hudson Bay.
Deep Bay, located at the south end of the lake and measuring about 5 km (3 mi) wide and 220 m (720 ft) deep, is the site of a large meteorite impact dating about 140 million years ago.
Fishing
Fishing is an important industry in the area and sport-fishermen are drawn by its clear and deep waters. Trophy-sized Pike are common at Reindeer Lake. The lake also supports commercial fishing.
