Manitoba has an abundant supply of surface water with many large lakes and thousands of smaller ones (chapter 2). However, much of the water is in the north or drains to the north where there is a sparse population. In the south dams and reservoirs have been constructed to conserve water in some areas, whereas in other places projects were designed to drain water from the land to make it suitable for cultivation. The province’s rivers offered enormous potential for hydroelectric power, much of which has now been exploited, starting with a small-scale project on the Little Saskatchewan River and progressing to large projects on the Winnipeg, Saskatchewan and Nelson rivers. Two thermal power stations at Brandon and Selkirk on the Assiniboine and Red rivers illustrate the need for an assurred water supply. Flooding has been a problem since the earliest days of the province, especially along the Assiniboine and Red rivers culminating in the 1997 “Flood of the Century” in the Red River Valley. Dams, diversions and ring dikes are used to divert the floodwaters to less critical areas.
The multi-purpose Stephenfield Reservoir 1 was created by the PFRA in 1963 by building a dam 2 across the Boyne River 3 that flows to the Red River with a spillway at its south end 4. The over two-mile long reservoir has a storage capacity of 4,400 dam3. It retains water for domestic, agricultural, and municipal use. A water treatment plant opened in 1999 supplies the surrounding RM of Dufferin and pipelines that lead to the western part of the RM of Grey and the hamlet of Haywood to the north. Stephenfield Provincial Park is now located on the south shore of the reservoir, although it is not visible on this old, small-scale photo 5. It provides facilities for swimming, boating, and fishing in the reservoir. Just north of the reservoir is the correction line between townships 6 and 7 6.
