Commenced in 1928, completed in 1935, and upgraded in 1971, Wyangala Dam is a major reservoir situated below the confluence of the Lachlan and Abercrombie rivers, located approximately 38 km (24 mi) upstream, east of Cowra.

A hydro-electric power station generates up to 22.5 MW (30,200 hp) of electricity from the flow of the water leaving Wyangala Dam with an average output of 42.9 GWh (154 TJ) per annum.

[2] A 7.5 MW (10,100 hp) station was initially constructed below the dam wall and opened in 1947,[7][8] and the new facility, managed by Hydro Power Pty Ltd,[1] completed in 1992.

[9] The Wyangala Station homestead site, which was originally settled by the Newham family, is under the water level and can only be seen when the dam is close to being dry.

[11] The 2022 south eastern Australia floods in late October and early November 2022 resulted in the dam releasing a record 230,000,000,000 litres (230,000,000 m3)/day.
