The Edgar Dam is an earthfill embankment saddle dam without a spillway, located offstream in the South West region of Tasmania, Australia.
The impounded reservoir, also formed with the Scotts Peak Dam and the Serpentine Dam, is called Lake Pedder which flooded Lake Edgar, a naturally forming fault scarp pond. The dam was constructed in 1973 by the Hydro Electric Corporation (TAS) as part of the Gordon River Power Development Scheme for the purpose of generating hydro-electric power via the Gordon Power Station. Water from Lake Pedder is diverted to Lake Gordon (formed by the Gordon Dam) via the McPartlan Pass Canal.[1]
