16.9: Lake Irwin on the Whitemud River

Lake Irwin 1, a PFRA project, was created in 1960 by building a dam 2 across the Whitemud River 3 that empties into the south end of Lake Manitoba after flowing through Neepawa and Gladstone. A riparian conduit 4 carries water through the dam into the river, and a spillway 5 bypasses the dam on the east side. Lake Irwin is the source for Neepawa’s municipal water supply and is also used for swimming, sailing, water skiing, and fishing. Although not shown on this image some cottage development has occurred around the lake. On this large-scale image, the original north/south 6 and east/west 7 section lines can be seen approaching the lake.
