Chapter 3: Geologic Structure and Landforms

3.83: The Dand Spillway South of Hartney

Not all spillways result from water emptying from one glacial lake to another. In some cases they were created when glacial meltwater was deflected by ice. An example is the Dand spillway—named for a hamlet just off the southwest corner of the photo. Meltwater flowed in the depression now occupied by Chain Lakes 1, a small intermittent stream 2 and two sloughs 3. The spillway, about 50 feet (15 m) below the surrounding land cuts through hummocky ground moraine. Light-toned crests 4 that result from rain splash and wind erosion on exposed soils indicate minor elevations. A minor esker-like ridge runs across the southeast corner of the photo 5.

Most of the land in the area is devoted to agriculture. Lighter-toned fields 6 have been cropped whereas darker-toned fields 7 have been left fallow. In some of the cropped fields the farmer has been cultivating the land in preparation for next year’s crop 8. Dugouts 9 are ubiquitous in this dry area of southwestern Manitoba. Gravel roads follow sections of the DLS system 10 whereas quarter sections are indicated by land use changes 11. PTH 23 12 traverses the area in the north, and at the date the photo was taken, so did the CN railway line 13 with a siding and an elevator at Underhill 14.
