Canberra: Statement of Water Flows
The volume of water in the region's storages at 30 June 2016 was 273,135 ML, an increase of 8,016 ML from the start of the 2015–16 year. This increase represents the increase in water volume in the region's surface water storages. This is the region's third consecutive annual increase in storage volume.
The Statement of Water Flows is provided in the table below. The statement presents the actual water flows associated with the water stores of the region that occurred during the reporting year, including flows corresponding to the accrual transactions shown in the Statement of Changes in Water Assets and Water Liabilities.
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.
