The McArthur Falls Generating Station consists of a powerhouse, spillway and dykes and has a name plate capacity of 59.7 MW (80,000 hp). The station, constructed between 1952 and 1955, is the newest and smallest of the six generating stations operating on the Winnipeg River.

The station components include an eight unit powerhouse with east gravity structure, an eight bay gated spillway with east and west gravity structures and a total of fifteen dykes. The dykes are divided by the spillway and powerhouse into the east dykes with a total length of 0.37 km (0.23 miles), the centre dykes with a total length of 0.58 km (0.36 miles) and the west dykes with a total length of 8.8 km (5.5 miles). The dam and the dykes impound Lac Du Bonnet.
