Burdekin: Statement of Water Flows
The volume of water in the region's surface and groundwater storages at 30 June 2016 was 1,979,038 ML, an increase of 406,036 ML from the start of the 2015–16 year. This was mainly due to the 19% increase in volume that occurred at Lake Dalrymple, the largest reservoir in the region.
The Statement of Water Flows is provided in the table below. The statement presents the actual water flows associated with the water stores of the region that occurred during the reporting year, including flows corresponding to the accrual transactions shown in the Statement of Changes in Water Assets and Water Liabilities.
Items in the statements are hyperlinked to the associated section of the Statement details. Methods used to derive item volumes are provided in the Reference information notes.
