A major augmentation of Wyangala Dam would deliver improved water security, drought resilience and flood attenuation benefits for the Lachlan Valley.
Transition to Water Infrastructure NSW
As of 1 July 2021, responsibility for the proposed Wyangala Dam Wall Raising project transitioned from WaterNSW to the Department of Planning, Industry and Environment’s Water Infrastructure NSW, which is a Division of the Water Group.
For project continuity, key project staff have also moved across and previous WaterNSW project specific contact points (i.e. email and phone numbers) are being forwarded.
There are many benefits which will be realised during and after the construction of this project. Key benefits driving the project include:
- dam storage capacity will be increased by 53 per cent
- approx. 21 GL per annum additional estimated yield for general security license use
- a significant improvement in:
- water security
- drought resilience
- flood attenuation for the Lachlan Valley
- local business and employment opportunities maximised throughout the project.
The Wyangala Dam wall raising is expected to:
- secure the region’s town water supplies, stimulating the growth of the regional economy and support future population growth
- improve productivity of primary industries
- provide greater certainty of water reliability to support additional investment by businesses, particularly in the agricultural sector, including:
- transitioning to higher yield agricultural products
- increasing stock levels.
