Salt Lake is a lake in the province of Saskatchewan, Canada. The lake is located south of Senlac, Saskatchewan in the west central part of the province. The lake was the site of the earliest known production of salt in the province. The salt was produced by the Senlac Salt Co. around 1920. The area is currently the site of significant heavy crude oil and natural gas production. There is a small hamlet named after the lake which mostly houses oil field workers.
