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.
16.66: Flooding Near St. Adolphe in 1997
St. Adolphe 1 is another community effectively protected by a ring dike 2. The photograph taken near the peak of the 1997 flood shows the extent of flooding in the area. The channel of the northward-flowing Red River is just discernable, more easily in the south 3 than in the north 4. Inside the dike there is no clear evidence of flooding. Also, several other areas 5 and individual dwellings 6 are protected by ring dikes. In some cases, though, diking has not been effective in protecting buildings 7, and farmland is completely flooded 8.
The flood played havoc with transport routes. PTH 75 9 is mostly covered, and the CN railway line just visible in the south 10 has almost completely disappeared. Similarly PR 200 runs through the village 11 and then disappears to the south 12, although trees and buildings projecting above the water 13 pick out its general route. Highway 210 passes through St. Adolphe 14, crosses the Red River 15, and then disappears 16. Along its route to the west, a racetrack is just visible 17.
The irregular white line in the south 18 is a band of snow remaining from a late snowfall in the spring of 1997.
