Daly: Statement of Water Flows
for the year ended 30 June 2017
The volume of water in the region's storages increased during the 2016–17 year; however, the actual volume of water storage could not be quantified. This increase represents the change in water volume in the region's aquifers. This is the region's first annual increase in aquifer storage in five years.
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.
