South East Queensland: Statement of Changes in Water Assets and Water Liabilities
Water availability in the South East Queensland region decreased by 351,008 ML during the 2015–16 year. This follows an increase in water availability during the previous year. The change in water available in the region at the end of the year is represented by the change in net water assets.
The Statement of Changes in Water Assets and Water Liabilities is provided in the table below. The statement is prepared on an accrual basis, and presents the changes in water assets and water liabilities that occurred during the reporting year. These changes include accrual transactions (e.g. allocations and forfeitures) and actual water flows, both natural and engineered.
Items in the statements are hyperlinked to the associated section of the Statement details. Methods used to derive item volumes are provided in the Reference information.
