Quantification approach  

Data source

The NSW Office of Water: Draft water sharing plan—Greater metropolitan unregulated river water sources.

 

Data provider

The NSW Office of Water.

 

Method

The estimated annual water abstraction under riparian right for stock and domestic purposes was extracted from Draft water sharing plan—Greater metropolitan unregulated river water sources.

The estimation of riparian requirements for stock and domestic purposes is based on a variety of inference techniques, professional judgement and local knowledge on water use, stocking rates, population and property shape.

 

Uncertainty

The volume was estimated. The uncertainty in this estimate is also estimated to be +/–30% to +/–50% based on professional judgment and established practice within the NSW Office of Water.

 

Approximations, assumptions, caveats/limitations

The draft water sharing plan indicates that the estimates of basic landholder requirements may be reviewed following the public exhibition of the draft.
