Big River (Saskatchewan)
Big River is a river in the west-central part of the Canadian province of Saskatchewan in the boreal forest ecozone of Canada. The river begins at Witchekan Lake in the RM of Spiritwood No. 496 and heads in a north-easterly direction before emptying into Cowan Lake at the town of Big River. Cowan Lake is the source for Cowan River, which is a major tributary of Beaver River. Beaver River then flows into Lac Île-à-la-Crosse and the Churchill River.
