Site description Blackstrap Coulee is close to the town of Dundurn, and about 50 km south of Saskatoon in Saskatchewan. The coulee, which was carved by an ice age river, features a man-made, steep-sided reservoir (Blackstrap Lake), a large shallow-banked, marshy lake (Indi Lake) and wooded valley slopes. It is about 25 km long by one km wide, and also contains a channel connecting the two lakes. Two dams hold back canal water to form Blackstrap Lake, making it much less marshy than Indi Lake. Before the dams were built, the bottom of Blackstrap Coulee was farmed. The west valley slopes are covered by a mixed grass prairie with wooded draws while the east slope contains extensive aspen and shrub woods. Blackstrap Lake contains a provincial park, a ski hill, a summer camp and two townsites, Thode and Shields, each with 20 or so year-round residences on the waters edge.
