Warragamba Dam Raising

Warragamba Dam Raising

In May 2017, the NSW Government released Resilient Valley, Resilient Communities - the Hawkesbury-Nepean Valley Flood Risk Management Strategy (Flood Strategy), providing a comprehensive long-term framework for the NSW Government, local councils, businesses and the community working together to reduce and manage flood risk in the Hawkesbury-Nepean Valley.

The strategy concluded that raising Warragamba Dam by around 14 metres is the best infrastructure option to reduce flood risk from floodwaters from the Warragamba River catchment. The Flood Strategy also includes a range of other infrastructure and non-infrastructure outcomes that must also be part of the solution for managing ongoing flood risk.

WaterNSW, as the owner and operator of Warragamba Dam, has commenced consultation on the proposal and will undertake the environmental assessment and detailed concept design.
