Buffalo Pound Lake is a eutrophic prairie lake in Saskatchewan, Canada, formed from glaciation about 10,000 years ago, on the Qu'Appelle River approximately 28 km north of Moose Jaw, 11 km east of Tuxford and 3 km north of Sun Valley. The lake gets its name from the method used by First Nations people to capture the bison using the natural topography as corrals or buffalo pounds. Bison once numbered more than 60 million, by 1900 they were all but extinct due to settlement. Bison were reintroduced into the area in 1972. The Qu'Appelle River was dammed by the Buffalo Pound Dam in 1939 to control fluctuating water levels.
