Supporting information

This line item volume (0 ML) represents the volume of groundwater allocation remaining for urban water supply licence entitlements in the Melbourne region at the end of the 2012–13 year.

Quantification approach

Data source

Victorian Water Register.

Victorian Department of Environment and Primary Industries.


Carry-over rules for groundwater entitlements throughout the Melbourne region do not allow unused water to be carried over at the end of the year. Therefore any unused water is forfeited and the volume reported at this line item is zero as shown in the following table.
