Fitzroy: Statement of Changes in Water Assets and Water Liabilities

For the water account period 1 July 2023 to 30 June 2024

  • The volume of water in Fitzroy's storages decreased by 35 GL during 2023–24, the first decrease in the region's water storages since 2019–20.
  • This decrease primarily represents the change in water volume in the region's surface water storages.

Schematic representation of the Fitzroy region. Total water inflows during 2023–24 was 4,001GL. Total water outflows was 4,362 GL. Water storage on 30 June 2024 was 35 GL less than the previous year.

The Statement of Changes in Water Assets and Water Liabilities is provided in the table below.
The statement presents the actual water flows associated with the region's water stores, as well as the changes in water assets and water liabilities that occurred during the year.
