Sydney: Statement of Water Flows

The Statement of Water Flows presents the actual water inflows and outflows associated with the water stores of the region that occurred during the reporting year.
Figure W3 shows the actual water flows, including flows corresponding to the accrual transactions shown in Figure W2 in the Statement of Changes of Water Assets and Water Liabilities.
