Whatshan Dam
Whatshan  Dam was built by the B.C. Power Commission and completed in 1952. It is a concrete hydroelectric dam on the Whatshan River in the Canadian province of British Columbia. The Whatshan powerhouse has undergone three major transformations since 1951 when it was first built by the British Columbia Power Commission to provide electricity to the Okanagan and the Upper Arrow Lakes in 1951. In 1953 the powerhouse was destroyed after a rock and mud slide roared down the mountainside.
