Murray–Darling Basin
2.5 Other groundwater assets

Supporting information

The volumetric value for the line item for the 2012–13 year was 4,193,166 ML for the Murray–Darling Basin (MDB) region. The line item includes long-term estimates of volumes for extraction, basic landholder rights or unlicensed stock and domestic rights (where these are not included in the long term extraction estimates in the water resource plan), and for New South Wales the volume of supplementary access licence that was available for use in the 2012–13 year.

Following two tables provide a summary and a breakdown of volumetric details of the line item. More details about the groundwater asset volumes and other data within the region are available in the Groundwater regional note.

GW13 New South Wales Great Artesian Basin Shallow water resource plan area includes 2,002 ML for Paroo alluvial and Warrego alluvial groundwater sources extracted from the Water Sharing Plan for the Intersecting Streams Unregulated and Alluvial Water Sources 2011.

Volumes provided in the above tables are based on information available at the sources (see 'Data source') at the data collection stage for the account. It is likely that any subsequent changes to groundwater information in the water resource planning areas after the data collection stage have not been included in the above tables. In addition, sustainable diversion limit (SDL) areas other than included in the above tables do exist and may be relevant to the line item; however, relevant information was not available for the account. For example, SDL areas for which approved groundwater plans are not available (i.e., the annual extraction limit has not been set by a water resource plan) are not included for the line item.

No information on groundwater asset volumes was available for Queensland and the Australian Capital Territory areas within the MDB region for the 2013 Account. This was due to the absence of statutory water resource plans for groundwater, and lack of reliable information in existing water resource plans and other sources. 

More information on basic rights within the MDB region is included in line item 18.7 Extraction: other statutory rights.

Quantification approach

Data source

Data were sourced from:
  • NSW Office of Water: water access licence statistics
  • jurisdictional groundwater plans
  • Victorian Permissible Consumptive Volume Groundwater Order 2011
  • Victorian Water Account 2011–12.

Provided by

The Bureau of Meteorology.

Method

The extractable volume of groundwater has been estimated as the sum of the following attributes as stated in the relevant groundwater plan, if there was such plan in place during the 2012–13 year:

  • long-term estimates of volumes for extraction
  • basic land holder rights or unlicensed stock and domestic rights (where these are not included in the long term extraction estimates in the water resource plan)
  • for New South Wales the volume of supplementary access licence that was available for use in the 2012–13 year.

If a plan commenced after 30 June 2013, it was excluded from the account. Where a plan was abolished after 30 June 2012, the value of the plan in effect for the 2012–13 year was included in the 2013 Account.

Basic landowner rights are added to the long-term annual extraction limits for those plans that do not include this extractable volume in the plan extraction limit to get an estimate of what is legally extractable from the aquifers. In addition, for New South Wales the volume of supplementary access licences for the 2012–13 year was included to better reflect the total volume of water that can be extracted from the aquifer for the 2012–13 year.

Assumptions, limitations, caveats and approximations

The basic landowner rights were considered as those at the commencement of the groundwater plan.

Uncertainty information

The uncertainty estimate was not quantified.
