Only the nominated groundwater management units for reporting in the National Water Account 2010 have been included in this table. Other GMUs units do exist and may have volumes for allocations.

 

Quantification approach   


Data source

Murray–Darling Basin Authority (MDBA).

 

Data provider

MDBA.

 

Method

Adjustment and forfeiture of groundwater allocation is calculated by deducting the allocation extraction from allocation announcement (stock and domestic class).

 

Uncertainty

Estimated uncertainty is ungraded.
