4.5: Field Shelterbelts North of Lyleton

During the 1930’s drought, soil erosion was severe in this dry flat area in the extreme southwest of Manitoba. Thin soils that had developed on hummocky ground moraine were easily blown away. The mottled appearance of several fields 1 results from the removal of dark-coloured soil constituents from slightly elevated areas.

From the earliest days of agriculture in the area, shelterbelts were built around farm buildings 2. A new strategy in response to the drought was the planting of field shelterbelts in north/south 3 or east/west 4 lines with trees brought from the tree farm at Indian Head in Saskatchewan. Farmers were also given grants for small-scale water projects such as the construction of dugouts 5 and small dams 6 to capture spring runoff. Gainsborough Creek 7, that flows west to join the Souris River (off the photo), is intermittent in this area and more a series of ponds 8—probably dam-created for water supply—rather than a continuous river. As is usual, roads follow section lines 9, and in two cases they are relatively newly constructed 10.
