Description Breton 1:50,000 Topographic Map The Breton 1:50,000 Topographic map is dominated by the Great Western Tiers escarpment. The elevated plateau, forming part of the Tasmanian Wilderness World Heritage Area, is subject to sudden and sometimes extreme weather changes. The plateau contains the large artificial impoundment yingina / Great Lake which feeds three hydroelectric power stations and is one of the state’s most important energy resources. Whilst this lake is popular with recreational fishers, other lakes on the plateau attract those fishers seeking a wilderness experience. The area below the escarpment is mainly devoted to production forestry and agriculture.
