20.9 Decrease of irrigation scheme inter-region claim on water

During the 2010–11 year the volume of water allocated to Barossa Infrastructure Limited (BIL) under their River Murray Class 3a water access entitlement (WAE) decreased by 3,826 ML. This volume included:

• 1,000 ML decrease in BIL's allocation volume due to an allocation trade

• 2,826 ML carryover of allocations for Class 3a WAE was not permitted at the end of the 2010–11 year. Therefore, the volume of 2,826 ML was the unused portion of the allocation volume for the entitlement.

For more information on the entitlement see line item 4.2 Irrigation scheme inter-region claim on water.

BIL operates the only irrigation scheme in the Adelaide region that imports water. At the start of the 2010–11 year, BIL had a WAE on the River Murray Prescribed Watercourse of 4,498,494 shares.

Allocation announcements: During the 2010–11 year the South Australian Government made seven incremental announcements notifying the volume of water available for allocation from the River Murray consumptive pool. These announcements were published in the South Australian Government Gazette. The allocations reached a maximum water allocation rate of 0.67 kL/share.

WAE trades and leases: BIL's WAE balance was reduced from 4,498,494 to 4,396,494 shares as a result of trades and leases. A trade and/or lease does not directly represent a volume of water that can be abstracted; rather it is a change in the share of the consumptive pool. The allocation balance is adjusted according to the WAE balance when an allocation announcement is made. If no allocation announcement is made after a trade or lease, there is no change to the allocation balance.

Allocation trades: During the 2010–11 year BIL received an allocation credit of 841 ML as a result of one trade. Allocation trades change the actual authorisations to take, irrespective of the number of shares. 

BIL's starting share balance, allocation announcements, trades to and from BIL involving shares and allocations are summarised in the following table.

• The volume reported at this line item only represents BIL's Class 3a entitlement to River Murray water and does not represent the increase in allocation volume for individual Class 3a licence holders within the Adelaide region.
• This volume reported in this line item includes increases due to allocation trade plus WAE trades and leases.

The uncertainty estimate was not quantified.

This line item is new to the 2011 Account due to the inclusion of a separate irrigation scheme store. The comparative year volume was not restated as these data were not available.
