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 photo shows the Roseau River Anishinabe First Nation 1 in May 1997, protected from flooding by a ring dike 2. Taken looking south-southwest, the photo shows the extent of flooding and the Red River channel to the right 3. The Roseau River flows into the Red River near the right hand edge of the photo 4. The east/west PR 201, which passes through the southern part of the First Nation 5, is completely flooded to east 6 and west 7.
