Quantification Approach

Data Source

NSW Office of Water (refer to the table provided under Supporting information): (1) water sharing plans and (2) catchment and climate modelling: estimates of basic rights for valleys that did not have a water sharing plan in place for the year.

Provided by

Murray–Darling Basin Authority.

Method

Diversion volumes were estimated to be equal to the value of the total volumetric basic landholder right as stipulated in the water sharing plan at commencement of the plan or the total riparian volumetric right as estimated by NSW Office of Water – Catchment and Climate Modelling where applicable.

Assumptions, Limitations, Caveats and Approximations

For New South Wales, no information on measured diversion volumes of riparian right water was available. The diversion volumes were estimated as described in above Method.

Uncertainty Information

The uncertainty estimate was not quantified.

Comparative year

The value reported as comparative year corresponds to the line item 14.5.1 Surface water diversion – riparian right that was reported in the 2010 Account.
