Murray–Darling Basin: Statement of Water Flows
The volume of water in the region's surface and groundwater storages at 30 June 2016 was 16,246,869 ML, a marginal increase of 454,400 ML from the start of the 2015–16 year. This primarily reflects an increase in river channel volume due to heavy rainfall that occurred near the end of the reporting period.
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.
