Canberra: Statement of Water Flows
The volume of water in the region's storages at 30 June 2017 was 279,006 ML, an increase of 5,871 ML from the start of the 2016–17 year. This reflects the increase in water volume of most of the region's surface water storages. This is the region's fourth consecutive increase in storage volume.
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.
