- Alameda Dam
Alameda Dam , (coord|49|15|32|N|102|13|51|W) near
Estevan, Saskatchewan , was constructed in 1994 to control flows on Moose Mountain Creek. It provides flood protection and irrigation for this area of Saskatchewan, and a supply of cooling water for the Shand Power coal generating station. The Alameda reservoir provides opportunities for recreational use such as boating and fishing. At the full supply level of 562.0 metres, the reservoir holds 105,000,000 cubic metres of water. The project is owned and operated by the Saskatchewan Watershed Authority.The Alameda dam is an earthfill dam 1660 metres long, with a height of 42 metres. The volume of earth in the main dam is nearly 3 million cubic metres. The dam is protected by a 224 metre long spillway with a maximum discharge capacity of 1400 cubic metres 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 square kilometres at full supply level. The surrounding drainage area is 2,140 square kilometres.
A full-time staff of about 5 persons 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 ofMinot, North Dakota . Operation of the project is governed by international treaty between Canada and the United States.References
