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.
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.
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.
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.

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 2010–11 year.
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 NSW Office of Water's quality assurance procedures may be incomplete. The NSW 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.
This corresponds to line item 27.1.2 Groundwater allocation announcement – urban class, 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.
|2010 Account line items||Segment||
Volume for the 2009–10 year reported in the 2010 Account (ML)
Difference due to presentation and classification change (ML)
Volume for the 2009–10 year reported in the 2011 Account (ML)
|27.1.2 Groundwater allocation announcement – urban class||Northern Basin||17,299||0||17,299|
Regrouping of line items was due to the reclassification of Aquifer – research entitlement class in the Lower Murray Alluvium SDL area from urban to non-urban category of entitlements.
