Wyangala Dam Wall Raising
The project will raise the current dam embankment and downstream rock fill to add an additional 650GL of storage to the dam. It will also raise the spillway and intake towers of the dam by 10m.
An increase in the dam storage capacity of 53 per cent will result in a significant improvement in drought resilience, water security, flood attenuation and water reliability for the Lachlan River.
The Australian Government has made a commitment of $325 million towards the project. Total cost of the project is still to be confirmed through the Detailed Business Case process.
Australian Government funding is provided through the National Water Grid Fund.
Planning is underway. Delivery timeframes including completion of construction will be informed by the Detailed Business Case.
