Additional information

SDL areas not shown in the table may have values relevant to the line item; however, relevant information was not available for the 2013 Account.

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.

There was 202 ML groundwater extraction in GS 8 Goulburn–Murray for urban use in Katunga (53 ML), Wangaratta (138 ML) and Goorambat (11 ML). This extraction was not included in this line item and included in line item 18.11 Entitled extraction of allocated groundwater to users because information on urban allocations had not been available. 

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

Bureau of Meteorology (the Bureau).

Method

Metered extractions were as compiled by the states.

Assumptions, limitations, caveats and approximations

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.
