Pinawa Dam, which began operating in 1906, was originally built to provide residential and commercial
hydroelectric power for the
city of Winnipeg. The dam was closed in 1951 to allow for the
Winnipeg River's full flow to enter the
Seven Sisters Generating Station. Parts of the dam were later used for demolition practice by the
Canadian Armed Forces, and were thereby destroyed. The Pinawa Dam Provincial Park today includes the ruins of the former dam, through which water flows and forms rapids and waterfalls. ==See also==
