Statement of Water Assets and Water Liabilities
- Water availability in the region increased from 2013–14 to 2016–17, reaching a peak in 2015–16.
- Water availability is represented by the net water assets, which are the volume of water assets minus the water liabilities.
The Statement of Water Assets and Water Liabilities is prepared according to the Australian Water Accounting Standard 1 and is like a balance sheet. It presents the volume of water assets and water liabilities at the start and end of the reporting year.
Water assets in the integrated water accounts for the Canberra region include water (physical water assets) and rights or claims to water (non-physical water assets). Water liabilities in the integrated accounts include commitments to deliver water to users.
