Tobin Lake is a reservoir along the course of the Saskatchewan River in the Canadian province of Saskatchewan. Tobin Lake was formed by the building of the E.B. Campbell Dam on the Saskatchewan River in 1963. The dam was originally named Squaw Rapids Dam, but was renamed E.B. Campbell Dam in 1988 as the term squaw is derogatory. The town of Nipawin is near the western end of the lake and upstream from Nipawin along the Saskatchewan River is , which was formed by the construction of the Francois Finlay Dam in 1986. Situated between these two man-made lakes, Nipawin earned the nickname The Town of Two Lakes.
