Patience Lake is a lake in central Saskatchewan, Canada east of Saskatoon. The lake is in the rural municipality of Butcher No. 343. Potash Corporation of Saskatchewan operates a solution mine with production of 331,000 tons of potash annually. Due to flooding in 1988 the Potash mine was converted to solution mine from its original construction as an underground mine. Patience Lake serves as a groundwater discharge region for higher elevations to the east and west.
