In the Greater Sydney region, WaterNSW manages a total of 21 storage dams (11 major dams) that can hold more than 2.6 million megalitres of water. Water for these dams is collected from five catchment areas covering 16,000 square kilometres.

WaterNSW is responsible for dam safety and for managing the water stored in all its dams and storages.
