Blackstrap Lake is a man-made lake in central Saskatchewan, Canada, south of Saskatoon in the rural municipality of Dundurn No. 314. The lake was created, for recreation, in 1967 by a dam located at its south end. The lake with an area 3000 acres (14.4 km x 0.8-1.2 km at a depths of 5.14 m) is used to support irrigation, industrial and municipal water supply.[1]
The lake forms part of Blackstrap Provincial Park and Blackstrap Ski Hill. The Blackstrap Coulee is 25 km long and consists of two lakes, Blackstrap Lake and Indi Lake that are connected by a small river; the lake beds were farmed during dry seasons prior to the dam being constructed.[2]
The Blackstrap North Dam (with a height of 10.4 m and length of 1,370 m) is operated by SaskWater and was constructed in 1967; the dam stores water to supply the village of Thode, the PCS Allan potash mine (via the Bradwell Reservoir) and Mosaic Colonsay potash mine (via Zelma Reservoir).[3] The Blackstrap South Dam (with a height of 7.9 m and length of 1,116 m) is operated by SaskWater and was also constructed in 1967.
