26.1.9.7 Adjustment and forfeiture of allocation on regulated flows—other lumped

                             

Supporting information   


The volume recognised in the water accounting statements (6,812 ML) represents the volume of:

  • water allocated during 2009–10 for regulated entitlements for self-supply licencees that was not abstracted during 2009–10, and is therefore forfeited
  • entitlements that were terminated during 2009–10.

The breakdown of forfeitures and terminations according to the stated licence entitlement purpose is provided in the table below.

 

Licence purpose Forfeiture (ML) Terminations (ML)
Agriculture 48 0
Commercial and institutional 478 0
Industry and power generation 0 0
Mining 6,277 0
Parks, gardens and recreation 0 0
Stock and domestic 9 0
Subtotal 6,812 0
Total adjustment and forfeiture for 2009–10 6,812

Method

Any unused allocation cannot be carried over to a subsequent licence year. The portion of a regulated entitlement that has not been abstracted at the end of the reporting period is forfeited. The forfeiture is calculated as:

Line item 25.1.9.7 Allocation announcement on regulated flows—other lumped

minus

Line item 14.7.9.7 Allocation diversion of regulated surface water flows—other lumped.

Entitlements that are terminated during the reporting period are also considered to be forfeitures.

 

Uncertainty

Ungraded.

 

Assumptions, approximations and caveats/limitations

Forfeiture is calculated based on available abstraction data. Where the abstraction data are estimated, the forfeiture is subject to the same assumptions and limitations of the abstraction data. Refer to Line item 14.7.9.7 Allocation diversion of regulated surface water flows—other lumped.
