Zelma Reservoir[1] is a reservoir in the Canadian province of Saskatchewan in the Rural Municipality of Morris No. 312. It is about 17 kilometres (11 mi) east-southeast of the town of Colonsay.[2] The reservoir was built in 1967 as part of South Saskatchewan River Project. That project, originating at Gardiner Dam of Lake Diefenbaker, involved the building of aqueducts, canals, and a series of reservoirs to supply water for irrigation, consumption, and industry. Other reservoirs in the system include Broderick Reservoir, Brightwater Reservoir, Indi Lake, Blackstrap Lake, Bradwell Reservoir, and Dellwood Reservoir.[3][4]
The BHP potash mine at Jansen gets its water supply from Zelma Reservoir through the Zelma East Non-Potable Water Supply.[5][6]
There are no communities along the reservoir's shores. Besides Colonsay, other nearby communities include Zelma and Young. There is a public boat launch at the north-east corner, near the dam[7] and access is from Highway 763.[8][9][10]
