20.9 Adjustment and forfeiture of irrigation scheme inter-region claim on water

Supporting information

The volume reported (486 ML) represents the total adjustment and forfeiture of Barossa Infrastructure Limited's (BIL) River Murray water access entitlement allocation during the 2012–13 year. Part of this volume (8 ML) is an allocation decrease due to termination of a lease-in of shares due to expire at 30 June 2013. The remaining part of this volume (478 ML) is unused allocated water that could not be carried over to the 2013–14 year.

Quantification approach

Method

Carry-over of unused water allocated against BIL's entitlement to River Murray Water was not permitted by the Government (BIL 2013); therefore the volume of water forfeited at the end of the 2012–13 year was calculated as summarised in the table below.

Calculation of adjustment and forefiture of unused allocated water at the end of the 2012–13 year
Account Volume (ML)
12.12 Increase of irrigation scheme inter-region claim on water 7,852
12.6 Delivery of water to irrigation scheme under inter-region agreement (7,366)
Adjustment and forfeiture of unused allocated water 486
