Quantification approach   


Data source

Western Australian Department of Water: Water Resource Licensing database.

 

Data provider

Western Australian Department of Water.

 

Method

Mundaring Reservoir is part of the urban water supply system, so it has the same licence agreements for water abstraction as the other 13 major reservoirs (see line item 25.1.2.4).

The total surface water allocation announcement is assumed to equal 100% of the annual entitlement.

 

Uncertainty

Not applicable.

 

Approximations, assumptions, caveats/limitations

The announced allocation is made after a review, by the Department of Water, of the surface water level of Mundaring Reservoir in October each year.
