The Gordon Dam (also known as Gordon River Dam), is a double curvature arch dam on the Gordon River in Tasmania, Australia. The dam has a length of 192 m (630 ft), and a height of 140 m (459 ft), making it the tallest dam in Tasmania and the fifth-tallest in Australia.
Water from the dam drops 183 m (600 ft) underground into its power station, where three turbines of 144 MW generates up to 432 MW of power, covering about 13% of the electricity demand of Tasmania. The first two turbines were commissioned in 1978, before the third was commissioned a decade later in 1988.
The completed Gordon Dam was the only dam built on the Gordon River, despite the support of Tasmanian politicians such as Eric Reece, Robyn Gray, and others to build the Franklin Dam further downstream.
The dam was designed with Dr. Sergio Guidici as the chief engineer. He went on to be involved with the design of the Crotty Dam in the West Coast Range, one of the last significant dams created by Hydro Tasmania during its unabated dam-building era.
