Groundwater allocations for irrigation occur in the Barossa Prescribed Water Resource Area (PWRA), Northern Adelaide Plains Prescribed Wells Area (PWA) and McLaren Vale PWA. Allocation, carryover and extraction data for 2009–10 were extracted from the WILMA licencing database and used to calculate adjustment and forfeiture (referred to as the ‘unused authorisation to take’ by Department for Water), as shown in the table below.
