About Lake Pedder
Originally a unique quartzite beach lake in the southwest wilderness, Lake Pedder was controversially flooded in 1972 to create a hydro-electric impoundment, sparking the creation of the modern Australian environment movement. Today the vast impoundment covering 242km² sits within the World Heritage Area and is used for trout fishing and remote camping, while the Pedder Impoundment Restoration project continues to campaign for restoration of the original lake. The surrounding Southwest National Park is reached via the road to Cockle Creek.
