Lake Gordon is a man-made reservoir created by the Gordon Dam, located on the upper reaches of the Gordon River in the south-west region of Tasmania, Australia.

Features

The reservoir was formed in the early 1970s as a result of the dam construction by the Hydro-Electricity Commission of Tasmania in order to create an upper storage for the Gordon Power Station, the largest and most controversial hydro-electric power scheme in Tasmania.[2]

Drawing from a catchment area of 1,280 square kilometres (490 sq mi), Lake Gordon has a surface area of 278 thousand square metres (3×10^6 sq ft), with storage capacity of 12,359,040 megalitres (436,455.4×10^6 cu ft)[1] or 12.5 km3 (3.0 cu mi) of water, the equivalent of twenty-five times the amount of water in Port Jackson. Lake Pedder is connected to Lake Gordon through the McPartlans Pass Canal at 42°50′51″S 146°11′45″E / 42.84750°S 146.19583°E / -42.84750; 146.19583 (McPartlans Pass Canal).

Additional dams were proposed for the lower Gordon River, however they were subject to political protest led by The Wilderness Society, most notably the Franklin Dam controversy during the early 1980s. In 1983 the Hawke-led Australian Government intervened and overturned a decision by the Tasmanian Government to dam the lower Gordon. When the Tasmanian Government refused to halt work in the UNESCO-listed World Heritage Area, the Australian Government successful sought a ruling in the High Court of Australia in Commonwealth v Tasmania. The lower Gordon was not dammed.[3]
