Grand Rapids Generating Station

In 1965, Manitoba Hydro began operation of the Grand Rapids Generating Station, located about 400 km (250 miles) north of Winnipeg. The 479-MW dam on the Saskatchewan River raised the level of Cedar Lake–which is part of the Saskatchewan River system–by about 3.5 meters (11.5 feet). The lake became a reservoir covering 3,500 square kilometers (1,350 sq miles). Among other impacts, flooding and erosion of shorelines cause trees to be washed into the river system. The above photos shows the resulting shoreline debris on the Cedar Lake reservoir. Debris prevents animals and boats from accessing the lakeshore. Photo courtesy of Ellen Cook, taken July 2009.

It doesn't matter how many times the shoreline is cleared, the following spring more debris accumulates. Photo courtesy of Ellen Cook, taken July 2009.


Eagles are nesting in spindly little willows on the shores of the Cedar Lake reservoir because the tree they had been nesting in rotted and fell over as a result of water fluctuations. Photo courtesy of Ellen Cook, taken July 2009.
