The W. A. C. Bennett Dam is a large hydroelectric dam on the Peace River in northern British Columbia, Canada. At 186 metres (610 ft) high, it is one of the world's highest earth fill dams. Construction of the dam began in 1961 and culminated in 1968. At the dam, the Finlay, the Parsnip and the Peace rivers feed into Williston Lake, also referred to as Williston Reservoir. It is the third largest artificial lake in North America as well as the largest body of fresh water in British Columbia. Williston Lake runs 250 kilometres north–south and 150 kilometres east–west.

The Site C Dam is a hydroelectric dam currently under construction on the Peace River, 14 kilometers southwest of Fort St. John in northeastern British Columbia, Canada. It is located approximately 80 kilometers downstream from the W. A. C. Bennett Dam. When completed in 2025, the Site C Dam will become the 4th largest producer of hydroelectricity in British Columbia with an expected capacity of 1,100 MW and an expected annual output of 4,600 GWh of electricity.
