Additional information

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.

This line item corresponds to line item 16.5.2 Groundwater allocation extraction – urban water access entitlement, 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.

 

Restatement of comparative year information made for the line item 18.12 Groundwater allocation diversion – urban water system

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)
16.5.2 Groundwater allocation extraction – urban water access entitlement	Northern Basin	9,552	0	9,552
	Southern Basin	1,748	–6	1,742
	Whole region	11,300	–6	11,294

 

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.
