Return to previous page


The Seven Sisters Generating Station is located approximately 90 km (60 miles) northeast of the City of Winnipeg, and approximately 72 km (45 miles) upstream of Lake Winnipeg on the Winnipeg River.

The Seven Sisters Generating Station consists of a powerhouse, spillway and dykes and has a name plate capacity of 180 MW (242,160 hp). The station was developed in two stages. The first stage was completed in 1931 and involved construction of three units. The second stage was completed in 1952 following World War II and involved construction of the additional three units.

The station components include a six unit powerhouse, a two bay gated sluiceway dividing a 27 bay spillway into two sections, two non-overflow dams, and north and south dykes. The dykes extend for 5.6 km (3.5 miles) upstream on the Winnipeg River's north shore and 7.2 km (4.5 miles) upstream on the south shore. The dam and the dykes impound Natalie Lake.
