Quantification approach

Data source

Water Resource Licensing database and licensee meter readings.

Provided by

Department of Water.

Method

The licensed water management year for all bore fields within the Perth region is 1 July–30 June. For these licences, any unused allocation at the end of the water management year is forfeited; therefore, the allocation remaining at the end of the reporting period is zero, as shown in the following table.
