South East Queensland
32.2 Surface water access entitlement for non–allocated diversions
Supporting information
The volumetric value for the line item at the end of the 2011–12 year was 31,258 ML.
This line item consists of two different types of entitlements:
- water licence diversions for stock and domestic use
- unsupplemented surface water licences
The number of stock and domestic water licences can be seen in the following table. Although not a volumetric licence, it is expected that around 2 ML will be diverted for each licence.
Water resource plan (WRP) area | No of water licences |
Estimated diversion |
Gold Coast | 27 | 54 |
Logan Basin | 259 | 518 |
Moreton | 292 | 584 |
Total South East Queensland (SEQ) region | 578 | 1,156 |
The volume of unsupplemented surface water licences can be seen in the table below.
Water resource plan (WRP) area | Nominal volume |
Gold Coast | 1,732 |
Logan Basin | 6,247 |
Moreton | 22,123 |
Total SEQ region | 30,102 |
Notes:
- In the Gold Coast WRP area there were 285 unsupplemented non-volumetric surface water licences, of which 213 were area-based licences for a total land coverage of 1,052 ha
- In the Logan Basin WRP area there were 468 unsupplemented non-volumetric surface water licences
- The Gold Coast and Logan Basin WRP area unsupplemented entitlements include entitlements both within and outside WSS and water management areas (WMAs)
- The nominal volume is defined in Schedule 4 of the Water Act 2000 (Qld) as the number used to calculate the entitlement holder's share of the water available to be taken by holders of entitlements in all entitlement groups in the water resource plan area.
The volume associated with riparian entitlement within WSSs could not be quantified for the 2012 Account.
Quantification approach
Data source
Queensland Department of Natural Resources and Mines (DNRM) Water Management System database.
Provided by
Method
Data on water licences for stock and domestic use and unsupplemented surface water licences was obtained from the DNRM Water Management System database.
Assumptions, limitations, caveats and approximations
The assumed diversion rate of 2 ML per property may not be appropriate for all users and adds uncertainty to the estimated volume of the entitlement.
Uncertainty information
The uncertainty estimate was not quantified.
