Burdekin: Statement of Water Flows
for the year ended 30 June 2018
- Total water storage in the region increased marginally during the 2017–18 year.
- The volume of water in the region's surface water storages decreased during the year; however, this decrease was roughly equal to the increase in water available in the region's aquifer storage.
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.
