22.1 Groundwater allocation announcements
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 following table shows the breakdown of groundwater allocations for groundwater management units in the Melbourne region during the 2011–12 year.
|Groundwater management unit||Licensed allocation (ML)||No. licences||Stock and domestic allocation (ML)||No. stock and domestic bores|
|Cut Paw Paw Groundwater Management Area (GMA)
|Deutgam Water Supply Protection Area (WSPA)—groundwater||5,082||148||392||196|
|Koo Wee Rup WSPA— groundwater||12,217||383||2,502||1,251|
|Nepean GMA 1||6,110||73||4,498||2,249|
|Wandin Yallock WSPA— groundwater2||2,933||188||168||84|
|Total allocation announcements||41,526|
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.
Groundwater allocations in the Melbourne region were calculated using the following methods.
Allocation announcements are equal to the licensed entitlement volumes for each groundwater management unit recorded in the Victorian Water Register.
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
The uncertainty estimate was not quantified.
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.
