16.27: The Area of Grand Rapids Dam

The Grand Rapids Dam 1, on the Saskatchewan River was the first major hydro station built in “northern” Manitoba to supply the south. With a fall of 36.5 metres it has the greatest head of any Manitoba hydro station. It was completed in 1968 and has a capacity of 472,000 kw. The dam built up water behind it into Cross Bay 2, necessitating the building of dikes 3 to prevent water overflowing onto surrounding land. The Saskatchewan River 4 now flows to the south of the forebay with Ukamasahaw Point 5 between the two water bodies.

Several route ways can be seen: 1) PTH 6 6 north from Winnipeg crosses the Saskatchewan River below the dam 7 on its way north to Thompson. Minor roads follow the dikes 8 and cross the Saskatchewan River on the dam; and 2) very obvious is a wide light-toned zone 9, an area cleared of vegetation, the route followed by power lines, both north and south of the dam. Narrower light-toned lines (10 and 11) are also power line routes.
