16.21: Water Supply Strategies in the Souris Valley

The international, interprovincial Souris River flows from Saskatchewan into North Dakota and then into Manitoba, south of Coulter. Shown here is the southernmost part of the Souris River in Manitoba 1 just after it has crossed the international border 2. The river, which has been artificially straightened, flows on the floor of a shallow spillway that used to carry water from glacial Lake Souris to the south to glacial Lake Hind to the north; its banks are marked by dashed lines 3. In this semi arid area of southwestern Manitoba water supply is a problem. Two coping strategies are illustrated: 1) several small dams have been built to hold back water on small creeks draining to the Souris 4; and 2), there are numerous dugouts 5 both for domestic and agricultural use.

Also of note on this photo is the lack of conformity between the DLS and the equivalent system used in the U.S.A. North/south section lines do not coincide 6; and because the U.S. system has a base line further south, a line of partial sections occurs along the border 7.
