Background

The Ruskin Dam was constructed along with the Western Canada Power Company's hydroelectric development of the Stave Valley. In 1912, the Stave Falls Dam

Stave Falls Dam is a dual-dam power complex on the Stave River in Stave Falls, British Columbia, Canada . The dam was completed in 1912 for the primary purpose of hydroelectric power production. To increase the capacity of Stave Lake, the dam was raised in 1925 and the Blind Slough Dam constructed...

 who had previously bought Western Canada Power in 1921. In November 1930, the dam was inaugurated and local businessmen and politicians celebrated by dining in its powerhouse. Only two generators were operational at first and the third was added in 1950. The first superintendent of the Stave Falls Dam is the namesake for Hayward Lake. In 1961, the provincial government took over BC Electric Company, the dam became the property of Crown corporation BC Hydro.

Design

The Ruskin Dam is a 59.4 m (195 ft) tall and 110 m (361 ft) long concrete gravity type. The dam creates a reservoir (Hayward Lake) with a 42000000 cubic metre capacity and 3 km² (741 acre) surface area. The dam sits at the head of a 953 km² (368 sq mi) catchment area

Operation

The Ruskin Dam is part of the Alouette-Stave Falls-Ruskin Hydroelectric Complex. Upstream of the dam is the Stave Falls Dam and power station at 49°13′47"N 122°21′20"W which has an installed capacity of 90 MW. Supplementing Stave Lake is water from Alouette Lake which is created by the Alouette Dam at 49°17′10"N 122°29′12"W, 11.5 km (7 mi) northwest of Stave Falls Dam. A 1067 m (3,501 ft) long tunnel connects Alouette Lake and Stave Lake. At the end of the tunnel is a penstock which feeds an 8 MW power station on the edge of Stave Lake at 49°22′16"N 122°18′47"W. Water released from Stave Falls Dam flows into Hayward Lake and is used by the Ruskin Dam for power generation.
