Victoria’s comprehensive approach to knowing and managing water resources is underpinned by monitoring, measurement and reporting of available water through the Victorian Water Accounts (VWA).

DEECA uses data from the Victorian Water Register and other sources to produce the VWA. The VWA provides a year-by-year overview of water availability and use across Victoria at a bulk supply level. This includes a detailed water account for each of Victoria's 29 river basins and 20 groundwater catchments.

Now in its 21st year, the report is available on the VWA website. The 2023–24 VWA saw dry conditions across much of southern and western Victoria following 2 years of above average rainfall. Total water use volumes were roughly 15% higher than the previous year.

The VWA’s information is a critical input to enabling water corporations and the Victorian Government to plan for climate change and a lower water availability future due though Annual Water Outlooks, Urban Water Strategies and the development of Victoria’s Water Security Plan and its detailed investigations.

VWAs for earlier years going back to 2003-04 remain available as PDFs on the VWA’s previous accounts webpage. For more reporting resources, please visit Water monitoring and reporting.

Preparation of the 2024–25 VWA is now underway, for release in 2026. Contact the water reporting team if you have any queries about the 2023–24 VWA, or if you wish to be notified when we release the next VWA.
