Patience Lake[1] is a lake in the central part of the Canadian province of Saskatchewan. The lake is east of Saskatoon in the Rural Municipality of Blucher No. 343. The lake serves as a groundwater discharge region for higher elevations to the east and west.
At the south end of the lake, Nutrien[2] operates a solution mine that produces 331,000 tonnes of potash annually and has an approximately 50 ha (120-acre) region of the lake sectioned off with an earth dyke that is used to store brine tailings and saturated KCl solution.[3] The potash mine was originally established as an underground mine, but due to flooding in 1988 it was converted to a solution mine.[4]
