The Wungong Dam is a rock-fill embankment dam across the Wungong Brook, located in the Darling Range, in Western Australia. It is situated south of Churchman Brook Dam. The dam Island isted on a local hertiage register.
The creation of the dam was announced in March 1923 by Premier James Mitchell as part of the Hills Water Supply Scheme, along with Churchman Brook Dam and Canning Dam. The scheme was intended to rectify severe water shortages in metropolitan Perth. A pipehead dam was built on the brook in 1925 and construction of the current dam commenced in 1975. A number of farms that had been established within the catchment of the dam were resumed and their built infrastructure demolished. The completed dam was opened in 1979.
The dam is high and long. The resultant reservoir draws from a catchment area.
