Burdekin
Water resources and systems

Introduction

The following set of notes provides water accounting statements for each of the water stores and systems within the Burdekin region during the 2013–14 year. Information on all water flows to and from each water store and system are presented in this note, including between-store flows and transfers that are not presented in the consolidated water accounting statements (which are shown in italics).

For more information about the region, please refer to the General description section of the 'Contextual information'. For more information on between-store flows and transfers that occur in the region, please refer to the Supporting information note.

 

Surface water

Statement of surface water assets and surface water liabilities

The Statement of Water Assets and Water Liabilities presents the volume of water assets and water liabilities at the start and end of the reporting year.

Surface water assets of the region include physical water assets (e.g., storages and rivers) and rights or claims to water. Surface water liabilities include commitments to deliver water to users at the end of the year. The closing net water assets are the volume of surface water assets in the region minus the surface water liabilities at the end of the reporting year (Table 1).

Statement of changes in surface water assets and surface water liabilities

The Statement of Changes in Water Assets and Water Liabilities shows the changes in water assets and water liabilities that occurred during the reporting year.

This statement is prepared on an accrual basis. Table 2 shows the transactions that change the surface water assets and surface water liabilities of the region, including accrual (non-physical) transactions and actual water flows (both natural and engineered).

Statement of surface water flows

The Statement of Water Flows shows the actual water inflows and outflows associated with the water stores of the region that occurred during the reporting year.

Table 3 shows the actual surface water flows, including flows corresponding to the accrual transactions shown in Table 2.

Groundwater

Statement of groundwater assets and groundwater liabilities

The Statement of Water Assets and Water Liabilities presents the volume of water assets and water liabilities at the start and end of the reporting year.

Groundwater assets of the region include physical water assets (e.g., water table aquifer and underlying aquifers) and rights or claims to water. Groundwater liabilities include commitments to deliver water to users at the end of the year. The closing net water assets are the volume of groundwater assets in the region minus the groundwater liabilities at the end of the reporting year (Table 4).
