Murray–Darling Basin
10.13 Other groundwater increases

Supporting information

The volumetric value for the line item for the 2012–13 year was 270,109 ML. The line item represents groundwater assets increases resulting from changes in long term extraction estimates and basic landowner rights within the Murray–Darling Basin (MDB) region (see the following table).

– = Data not available

Increased long term extraction estimates and basic landowner rights were the result of implementation of new groundwater sharing plans during the 2012–13 year.

Quantification approach

Data source

The data sources were:

  • jurisdictional groundwater sharing plans
  • New South Wales Office of Water: water access licence statistics 
  • Victorian Permissible Consumptive Volume Groundwater Order 2011 
  • Victorian Water Account 2011–12.

Provided by

Bureau of Meteorology.

Method

Values were extracted from cited data sources.

Assumptions, limitations, caveats and approximations

It has been assumed that groundwater basic right is included in the permissible consumptive volume provided in relevant water sharing plan if no information is available to decide otherwise.

Uncertainty information

The uncertainty estimate was not quantified.
