Adelaide: Statement of Water Flows

City of Adelaide, South Australia (iStock © Ben Goode)

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.

More detail on the water flows for the 2014–15 year is provided in the Statement of Water Flows 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.
