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]
