The W. A. C. Bennett Dam is a large hydroelectric dam in northern British Columbia. It is named after the late former premier W. A. C. Bennett, and came on-line in 1968.
The complex consists of the main earth fill dam, which holds back Williston Lake, and the underground Gordon M. Shrum Generating Station. It is one of the largest hydro dams in the world, and is capable of generating 2,730,000 kilowatts of electricity at peak capacity.
