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.
16.46: The Red River Valley Near Emerson
The photo shows part of the Red River Valley on either side of the Canada/U.S. border 1 drained by the northward-flowing Red River 2. The only other drainage channels identifiable are Riviere aux Marais 3, a left bank tributary of the Red and Main Drain 4 that enters the Roseau River (off the photo to the north), a right bank Red tributary.
The town of Emerson 5 (population of 689 in 2006) is located just north of the international border with West Lynn to its west 6, and Pembina 7 just to the south of the border. Letellier 8 is located near the northern edge of the photo.
Several transport routes follow the Red River Valley. The main road is PTH 75 9 which becomes #29 10 in the U.S.A. Two minor roads are located east 11 and west 12 of the Red River, and highway 200 runs northeast from Emerson 13 and then north 14 to Dominion City (off the photo). The only prominent east/west road is PR 201 15 which passes through Letellier.
Railway lines are also prominent: the CN line 16 parallels PTH 75 and then splits in the south, one branch running into the U.S.A. 17 and the other southeast into Emerson 18. The CP line runs east of the Red River 19. Three lines converge on Emerson from the northeast 20, southeast 21, and south 22.
