Geosite description: Lake Burbury was created in the early 1990’s by damming of the King River for hydro-electric power. It is now a popular place for trout fishing and recreation. From Crotty Dam the water is fed through a 7 km-long tunnel to the John Butters Power Station, south of Queenstown. The former smelting township of Crotty was drowned by the lake, as were the sawmilling township of Princess River and a section of the original Lyell Highway. The lake is 24 km long.
The view west across the lake is of the central part of the West Coast Range, a dominant feature of western Tasmanian topography, mining and history. In the centre of the view is Mt Owen, with North Owen Peak at its right-hand end. To the right of this is the Linda Valley (with the Mt Lyell Mine at its head) followed by the ridge of Mt Lyell itself. Further right is the Sedgwick Plateau, with the dolerite ‘pimple’ of Mt Sedgwick rising above it. To the left (south) of Mt Owen can be seen part of Mt Huxley, then the Thureau Hills and part of Mt Jukes.
