Data source

Western Australian Department of Water: Water Resource Licensing database.

Data provider

Western Australian Department of Water.

Method

There is only one groundwater irrigation licence within the Perth region (Chittering Valley). In this case, no metered data are available and, therefore, the volume of extraction is estimated to be the full annual allocation amount.

Uncertainty

Ungraded.

Approximations, assumptions, caveats/limitations

There is insufficient information relating to actual groundwater extraction for the Chittering Valley Irrigation Scheme to provide a more accurate estimate of extraction for this licence.
