Wyangala Dam is located in the Lachlan Valley, near Cowra. The project would increase Wyangala Dam's storage capacity by 650 gigalitres through raising the dam wall by 10 metres to improve flood management and drought security.


This project is a controlled action under the Environment Protection and Biodiversity Conservation Act 1999 and will be assessed under the bilateral agreement between the NSW and Commonwealth Governments, or an accredited assessment process. For more information, refer to the Department of Agriculture Water and the Environment's website.
