Murray-Darling Basin
18.11 Groundwater allocation extraction

Supporting Information

The volumetric value for the line item for the 2010–11 year was 333,912 ML. The line item represents groundwater allocation diversion (excluding urban water systems) associated with a number of entitlement classes in the Murray–Darling Basin (MDB) region. Information on groundwater allocation diversions for urban water systems is included in line item 18.12 Groundwater allocation diversion – urban water system.

The following two tables provide a summary and breakdown information on groundwater allocation diversion (excluding urban water systems) within the region.

Additional information

Allocations may be made for urban, stock and domestic or irrigation purposes under a single class of licence in the particular water resource plan area. Where the purpose was not known, and it was a general class of licence, the groundwater allocation announcement has been included under Aquifer class.

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 for Aquifer and Aquifer (general security) classes.

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.

Water sharing plans were yet to commence or data were unavailable for the groundwater SDL areas listed in the following table.

Quantification Approach

Data Source

(1) New South Wales: NSW Office of Water's Water Access Licence Statistics, (2) South Australian Department for Water: Water Information and Licence Management Administration (WILMA) database, and (3).water audit monitoring (WAM) data received from Australian Capital Territory (13 January 2012) and Victoria (31 January 2012). WAM data are stored in the Murray–Darling Basin Authority HYDRO database.

Metered extractions were as compiled by the states.

Uncertainty Information

The uncertainty estimate was not quantified.

Comparative year

This line item corresponds to line items listed in the following table and reported in the 2010 Account. In the 2011 Account, the following change was made that caused the 2009–10 year value to be restated:

  • Presentation and classification of the line items has changed since the 2010 Account; line items have been regrouped.

The changes and their respective values are detailed in the following table.
