Murray–Darling Basin: Statement of Water Flows
for the year ended 30 June 2017
The volume of water in the region's storages at 30 June 2017 was 22,150,485 ML, an increase of 5,903,616 ML from the start of the 2016–17 year. This increase primarily represents the change in water volume in the region's surface water storages.
The Statement of Water Flows is provided below and presents the actual water flows associated with the region's water stores during the year, including flows corresponding to the accrual transactions shown in the Statement of Changes in Water Assets and Water Liabilities.
