Cardinia is Melbourne's second largest reservoir, and can transfer water to most parts of Melbourne depending on how our supply system is managed. It receives water from Silvan Reservoir, as well as the Victorian Desalination Plant (when in operation).
The dam at Cardinia Reservoir is a rolled earthfill and rockfill embankment, and was completed in 1973.
