22.1 Groundwater allocation announcements

Supporting information

The volume presented in the water accounting statements (41,526 ML) represents groundwater allocations for licensed entitlements and stock and domestic entitlements in groundwater management units in the Melbourne region during the 2011–12 year:

  • Groundwater allocations for licensed entitlements were equal to the sum of licensed entitlement volumes held in groundwater management units in the Melbourne region during the 2010–12 year.
  • Groundwater allocations for stock and domestic entitlements were equal to the sum of stock and domestic entitlement volumes held in groundwater management units in the Melbourne region during the 2011–12 year.
The volume reported does not include urban groundwater allocations for licensed entitlements.

The following table shows the breakdown of groundwater allocations for groundwater management units in the Melbourne region during the 2011–12 year.

1–2 The 2011–12 allocation exceeds the permissible consumptive volume in the Wandin Yallock and Nepean groundwater management units because dairy wash licenses were included in the groundwater licensing framework. Permissible consumptive volumes were not adjusted at the time of publication to reflect this change.

Quantification approach

Data source

Victorian Water Register.

Provided by

Victorian Department of Environment and Primary Industries.

Method

Groundwater allocations in the Melbourne region were calculated using the following methods.

Groundwater allocations

Allocation announcements are equal to the licensed entitlement volumes for each groundwater management unit recorded in the Victorian Water Register.

Stock and domestic entitlements

The groundwater allocation for stock and domestic entitlements was equal to the number of stock and domestic bores in groundwater management units (recorded in the Victorian Water Register) multiplied by the 2 ML entitlement per bore.

Assumptions, limitations, caveats and approximations

Nil.

Uncertainty information

The uncertainty estimate was not quantified.

Comparative year

In the 2011 Account, it was not possible to separate urban and non-urban entitlements to groundwater. Therefore, the volume of groundwater allocated for all groundwater entitlements was reported at line item 22.1 'Groundwater allocation announcements'.

In the 2012 Account, data provided has enabled non-urban entitlements to groundwater to be reported separately in the Melbourne Account.

Consequently, the volume has been restated from 39,545 ML (as published in the 2011 Account) to 39,370 ML.
