Wyangala Dam Wall Raising
Wyangala Dam Wall Raising
Subscribe for updatesA major augmentation of Wyangala Dam will deliver improved water security and flood mitigation benefits for the Lachlan Valley.
In October 2019 the Prime Minister and NSW Premier announced the planning and delivery of three new or augmented dams in NSW. Included in this package was the raising of Wyangala Dam wall to improve water security and drought resilience in the Lachlan Valley.
Wyangala Dam Wall Raising is estimated to cost $650 Million and increase storage by 53% by creating capacity for an additional 650 gigalitres. The project will involve raising the dam wall by around 10 metres, with the exact height and new full supply level to be confirmed throughout the next six to nine months as further detailed investigations, technical assessments and site inspections are undertaken.
The Wyangala Dam Wall Raising Project was identified in WaterNSW’s 20-year Water Infrastructure Study and was selected due to its initial feasibility study and ability to provide the Lachlan Valley greater water security.
