Water availability in the Adelaide region increased by 7,001 ML during the 2015–16 year. This is an improvement compared with 2014–15, where a 28,936 ML decline in water availability was observed. The change in water available in the region at the end of the year is represented by the change in net water assets.


Figure depicting statement of changes in water assets and water liabilities. Total forfeitures: 50,770 ML, Total water allocations: 112,310 ML, Total water asset decreases 541,062 ML, total water asset increase: 335,966 ML, change in net water assets: 7,001ML and unaccounted for difference 136,555 ML

 

 

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.
