The NSW Government has confirmed the Wyangala Dam Wall Raising project will not proceed because of the billions of dollars in construction costs and the potential catastrophic environmental impacts.
Both the project’s Final Business Case and an extensive independent review by Infrastructure NSW have recommended not raising the dam wall because it doesn’t stack up financially or environmentally.
Business case
The department carried out detailed investigations into a proposed raising of the Wyangala Dam wall. The Final Business Case is now available.
Download the Final Business Case (PDF. 94,600KB)While raising the wall of Wyangala Dam is not viable, we recognise the challenges of water security, reliability and flood mitigation for Lachlan communities do not go away.
It is why the region needs a multi-faceted approach to protect against uncertainties and balance the competing needs of our environment, towns, and farmers.
The Lachlan Regional Water Strategy provides a clear roadmap of how the government will tackle water security in the region over the next 20 years.
Be assured all decisions will be based on evidence, including state-of-the-art climate science, so the valley is in a stronger position to manage water in a changing climate.
We thank all stakeholders for their time and insights throughout development of the Final Business Case and the strategy, as well as their continued engagement as we implement the actions within the strategy.
We recognise that we have a shared vision to deliver the best outcomes for the Lachlan Valley.
