Quantification approach

Data source

See the 'Data source' stated in the table provided under 'Supporting information'.

Provided by

Bureau of Meteorology (the Bureau).

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.

Assumptions, limitations, caveats and approximations

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

Uncertainty information

The uncertainty estimate was not quantified.

Comparative year

A calculation error in the 2011 Account resulted in the restatement of the 2010–11 year volume. An error resulted in underestimation of diversion volumes related to other statutory right for Namoi SDL area in the 2011 Account. Associated correction was 365 ML. The respective volumes associated with the change are detailed in the following table.
