Burdekin: Statement of Changes in Water Assets and Water Liabilities

Spillway at the Burdekin Falls Dam, North Queensland © CSIRO

The Statement of Changes in Water Assets and Water Liabilities presents the changes in water assets and water liabilities that occurred during the reporting year.

This statement is prepared on an accrual basis. The changes in water assets and water liabilities are recognised when the claim to water or the obligation to deliver it is recorded and not when the actual flow occurs. Figure W2 shows the transactions that change the water assets and water liabilities of the region, including;

  • accrual (non-physical) transactions, indicated by the glass-of-water symbols
  • actual water flows (both natural and engineered), indicated by the arrows.

More detail on the changes in water assets and water liabilities for the 2014–15 year is provided in the Statement of Changes in Water Assets and Water Liabilities below.

Items in the statements are hyperlinked to the associated section of the Supporting information notes. Methods used to derive line item volumes are provided in the Quantification approaches notes.
