South East Queensland
17.7 Entitled diversion of non-allocated surface water to users

The volumetric value for the line item at the end of the 2012–13 year was 9,035 ML.

This line item includes:

• water licence diversions for stock and domestic use
• unsupplemented surface water licence/allocation diversions
• riparian entitlement diversions within water supply schemes (WSSs).

The stock and domestic, riparian entitlement, and unsupplemented surface water licence/allocation diversions in the South East Queensland (SEQ) region can be seen in the following table.

 

Estimated diversions on water licences for stock and domestic use, riparian entitlements, and unsupplemented surface water licence/allocation 

Water resource plan (WRP) area	Water licence diversions for stock and domestic use		Riparian entitlement diversion within WSS  (ML)	Unsupplemented surface water licence/allocation diversions (ML)
	Number of water licences	Water licence estimated diversion (ML)
Gold Coast	92	184	0	144
Logan Basin	69	138	79	0
Moreton	263	526	135	7,829
Total SEQ region	424	848	214	7,973
Total SEQ region diversion		9,035

Riparian entitlement diversions were for Warrill Valley, Lower Lockyer, and Logan River. The riparian allowance figure does not include either Mary or mid Brisbane (unknown). 

Department of Natural Resources and Mines (DNRM): data on stock and domestic use (from the Water Management System database); Seqwater: data on reparian entitlements and unsupplemented surface water licence/allocation diversions.

DNRM; Seqwater.

An estimate has been made of the water licences for stock and domestic use of water within the SEQ region. The total number of properties with water licences for stock and domestic use was multiplied by an assumed diversion rate of 2 ML per property to obtain an estimate of the volume abstracted.

Riparian entitlement diversions were obtained from Seqwater.

 

The assumed diversion rate of 2 ML per property may not be appropriate for all users and adds uncertainty to the estimated value.

Derived from estimated data. The uncertainty estimate was not quantified.

An error was made calculating the 2011-12 year volume published in the 2012 Account due to  exclusion of unsupplemented surface water licence/allocation diversions, and also in the estimate of number of stock and domestic licences plus riparian entitlement diversions. Consequently, the volume has been restated from 2049 ML (as published in the 2012 Account) to 9,035 ML.
