Murray-Darling Basin
14.1 Adjustment and forfeiture of groundwater allocation
Supporting Information
The volumetric value for the line item for the 2010–11 year was 880,045 ML. The line item represents adjustment and forfeiture of allocation in groundwater resource plan areas excluding urban water systems within the Murray–Darling Basin (MDB) region. Information on adjustment and forfeiture of groundwater allocation for urban water systems is included in line item 14.2 Adjustment and forfeiture of groundwater allocation – urban water system.
The following two tables provide a summary and a breakdown of volumetric details of the line item.

Note: Sustainable diversion limit (SDL) areas other than included in the tables may have values relevant to the line item, however, relevant information was not available for the 2011 Account.
Additional information
With the exception of the Angas Bremer Prescribed Wells Area (PWA), carry-over was not available either at the beginning or at the end of the year. Therefore all unused allocated groundwater was forfeited.
Values for the Gwydir Alluvium water resource plan area do not distinguish if they are for GS29 Lower Gwydir Alluvium or GS47 Upper Gwydir Alluvium. The volumes for these are reported as a combined value under GS29 Lower Gwydir Alluvium.
GS29 Lower Namoi Alluvium contains volumes sourced from the Lower Namoi Groundwater Source.
GS45 Peel Valley Alluvium – aquifer reports a combined volume based on water licences – aquifer and water licences – aquifer (general security).
It was not possible to distinguish between the volumes for GS51 Upper Namoi Alluvium and GS52 Upper Namoi Tributary Alluvium. Volumes reported here under GS51 Upper Namoi Alluvium are sourced from the following groundwater sources:
Upper Namoi zone 1 Borambil creek
Upper Namoi zone 2 Cox's Creek (Mullaley to Boggabri)
Upper Namoi zone 3 Mooki Valley (Breeza to Gunnedah)
Upper Namoi zone 4 Namoi valley (Keepit Dam to Gin's Leap)
Upper Namoi zone 5 Namoi Valley (Gin's Leap to Narrabri)
Upper Namoi zone 6 Tributaries of the Liverpool Range (South to Pine Road)
Upper Namoi zone 7 Yarraman Creek (East of Lake Goran to Mooki River)
Upper Namoi zone 8 Mooki Valley (Quirindi – Pine road to Breeza)
Upper Namoi zone 9 Cox's Creek (upstream Mullaley)
Upper Namoi zone 10 Warrah Creek
Upper Namoi zone 11 Maules Creek
Upper Namoi zone 12 Kelvin Valley.

Method
Adjustment and forfeiture of groundwater allocation was calculated by deducting the allocation extraction from allocation announcement.
Adjustment and forfeiture for Angas Bremer in South Australia was calculated by deducting the allocation extraction and the carry-over from allocation announcement.
