Daly: Statement of Changes in Water Assets and Water Liabilities

For the water account period 1 July 2024 to 30 June 2025

  • The volume of water in the Daly region's storages increased by 10 GL during 2024–25.
  • This increase is entirely from changes to the water volume in the region's surface water storages.

Schematic representation of the water flows associated with the Daly region's water stores, as well as the change to the region's water storage during the current reporting period.

The Statement of Changes in Water Assets and Water Liabilities provides a detailed breakdown of the actual water flows associated with the Daly region's water stores over the past six water accounting periods ending 30 June, as well as the changes in water assets and water liabilities that occurred during each reporting period.
