Moran Dam

Moran Dam, also called High Moran Dam or Moran Canyon Dam, was a 1950s proposal to dam the Fraser River in the Canadian province of British Columbia (BC). The structure was planned in the wake of devastating floods in a time of rapidly growing power demand, and if built, would have powered the largest hydroelectric facility in North America. After a protracted environmental battle, Moran Dam was defeated in 1972, mainly over concerns of its adverse impact on salmon populations in the Fraser River basin. The shelving of the project also influenced cancellation of other hydro developments along the river, and today the Fraser remains one of the most productive salmon fisheries on the continent.
