Churchman Brook Dam
Churchman Brook Dam is an earth-fill embankment dam approximately 30 kilometres (20 mi) southeast of Perth, Western Australia in the City of Armadale. The reservoir is a water source for Perth.
It has a capacity of 2.24 gigalitres (79 million cubic feet) for a catchment area of 16 square kilometres (6.2 sq mi).
The creation of the dam was announced in March 1923 by Premier James Mitchell. Along with Canning Dam and Wungong Dam, it formed part of the Hills Water Supply Scheme which was intended to rectify severe water shortages in metropolitan Perth. Its capacity was initially estimated at 595 million gallons.
Construction of the dam commenced in 1923 and was completed in 1929; the resident engineer was Sir Russell John Dumas.
