Daly
18.7 Groundwater extractions – other statutory rights

Supporting information

The volume recognised in the water accounting statements (4,275 ML) represents the volume of groundwater extracted under other statutory rights in the Daly region during the 2011–12 year.

These extractions are made by individual users for stock and domestic purposes. Total volume of extractions from each groundwater resource within the Daly region during the 2011–12 year are shown in the table below.

Method

The volume presented for this line item is an estimate. The estimated data are based on water allocation plans for the relevant groundwater resource or spatial assessments that factor in variables such as number of properties, stock water requirements and distance stock must travel for water.

More information on water allocation plans in the region (Tindall and Oolloo aquifers) can be found at the Department of Land Resource Management website.

Assumptions, limitations, caveats and approximations

There is not sufficient information relating to actual extraction to provide more accurate estimates of extractions by individual users under statutory rights. The entire volume extracted by individual users is based on estimated data.

Uncertainty information

The uncertainty is unquantified.
