14.1 Adjustment and forfeiture of groundwater allocation
The volume presented in the water accounting statements (28,353 ML) represents the volume of groundwater allocation that was forfeited for groundwater entitlements in the Melbourne region during the 2011–12 year. Carryover rules for groundwater entitlements throughout the Melbourne region do not allow unused water to be carried over at the end of the year. Therefore the volume of groundwater forfeited is equal to the volume of unused allocated water.
The volume reported does not include urban adjustment/forfeitures of groundwater allocations for licensed entitlements.
The volume of water forfeited at the end of the 2011–12 year was calculated by subtracting the volume of groundwater extracted from the volume of water groundwater available for extraction. This calculation is summarised in the following table.
|22.1 Groundwater allocation announcements||41,526|
||18.11 Entitled extraction of allocated groundwater to users||13,173|
|equals||Forfeiture on 30 June 2012
Assumptions, limitations, caveats and approximations
In the 2012 Account, data provided to the Bureau has enabled allocation and extraction volumes for non-urban entitlements to groundwater to be reported separately in the Melbourne Account.
Consequently, the volume has been restated from 30,626 ML (as published in the 2011 Account) to 29,186 ML.
