The Grant Devine Dam, formerly Alameda Dam, is an embankment dam 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. The Grant Devine Reservoir provides opportunities for recreational use such as boating and fishing. At the full supply level of 562 m, the reservoir holds 105000 dam3 of water. The project is owned and operated by the Saskatchewan Water Security Agency (formerly Saskatchewan Watershed Authority).

Structure

The Grant Devine Dam is a 1660 m long earthfill dam, with a height of 42 m. The volume of earth in the main dam is 2900000 m3. The dam is protected by a 224 m long spillway with a maximum discharge capacity of 1400 m3 per second.

The dam includes a low-level outlet structure for discharge of water to maintain the quality of the riparian environment downstream of the project, and for irrigation outflow.

The reservoir has a surface area of 12.4 km2 at full supply level. The surrounding drainage area is 2140 km2.

A full-time staff of about five people supervises and operates this dam and the Rafferty Dam built at the same time. Together, the two projects provide flow control on the Souris River and flood protection for the city of Minot. Operation of the project is governed by an international treaty between Canada and the United States.

Moose Creek Regional Park

Moose Creek Regional Park () is a regional park on the east side of the reservoir, 3 km north of the dam. The park encompasses about 3/4 of a section, which is about 480 acres. The park is 3 km east of Alameda off of Highway 9 and 6 km north of Oxbow off of Highway 18. The park features full-service camping, tenting, picnicking, swimming, boating, and fishing. There is also Moose Creek Golf Club, a 9-hole golf course. The third weekend in June each year, the Alameda Fishing Derby takes place on the lake.
