Additional information

SDL areas other than included in the tables may have values relevant to the line item, however, relevant information was not available for the 2012 Account.

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 in line item 22.1 'Groundwater allocation announcements' under 'Aquifer' entitlement class.

GS 32 NSW Border Rivers Alluvium includes both upstream Keetah Bridge and downstream Keetah Bridge alluvial groundwater sources.

GS 33 NSW Border Rivers Tributary Alluvium includes Macintyre and Ottleys Creek alluvial groundwater sources. 

Volumes reported here under GS47 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 Reservoir 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 (up-stream Mullaley)
  • Upper Namoi zone 10 Warrah Creek
  • Upper Namoi zone 11 Maules Creek
  • Upper Namoi zone 12 Kelvin Valley.

Quantification approach

Data source

New South Wales Office of Water: water access licence statistics.

Provided by

Bureau of Meteorology (the Bureau).


Allocation announcements were as calculated by the States.

Assumptions, limitations, caveats and approximations

  • The calculation of water made available may be affected by licences that have been cancelled or created part way through the 2011–12 year.
  • Information for New South Wales is based on data available in New South Wales Office of Water's water access licence statistics at the data collection stage. It is possible that changes if any from subsequent update to that data base have not been included in this line item.
  • The New South Wales Government does not guarantee that data are current nor does it guarantee that the data or the data capturing processes are free from corruption or error. Data provided are preliminary and New South Wales Office of Water's quality assurance procedures may be incomplete. The New South Wales Office of Water cannot warrant and does not represent that the material that appears on its website or any linked websites is complete, current, reliable and/or free from error.
