Ord: Statement of Water Flows
for the year ended 30 June 2018
- The volume of water in the region's storages decreased during the 2017–18 year.
- This decrease represents the change in water volume in the region's surface water storages. This follows a large annual increase in storage last year.
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.
