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.
Here the northeastward-flowing Souris River 1 has incised meanders into the surrounding landscape. One meander encircles the village of Wawanesa 2, while another northeast of the village has been abandoned 3. At the time the photo was taken five items of infrastructure crossed the river. Furthest upstream is a buried pipeline 4. South of the village, close to each other is a road bridge 5 and a railway bridge 6. The approaches to both were washed out in a large flood in 1976; only the road bridge was restored. North of the village, a weir 7 with rapidly flowing water downstream 8 holds back water for municipal water supply. The river channel is wider above the weir 9 than it is below 10. A second highway bridge 11 carries PR 340 northwards out of the village towards Brandon.
