The Grant Devine Dam, formerly Alameda Dam,^[1] is an embankment dam located in the Canadian province of Saskatchewan near Alameda and Oxbow. It was constructed in 1994 to control flows on Moose Mountain Creek and Souris River. It provides flood protection and irrigation for this area of Saskatchewan, along with protection for Minot, North Dakota.^[2] The Grant Devine Reservoir provides opportunities for recreational use such as boating and fishing. At the full supply level of 562 metres (1,844 ft), the reservoir holds 105,000,000 m³ (3.7×10⁹ cu ft) of water. The project is owned and operated by the Saskatchewan Water Security Agency (formerly Saskatchewan Watershed Authority).
