12.12 Increase of irrigation scheme inter-region claim on water

Supporting information

The volume reported (7,852 ML) represents the volume of River Murray water allocated to Baroosa Infrastructure Limited (BIL) under class 3a water access entitlements (WAE), owned or leased to BIL during the 2012–13 year. The allocation increases to BIL's River Murray water access entitlement are detailed in the following table.

867 purchase of allocated NSW Murray water 
2,368 purchase of allocated Victorian Goulburn–Murray water
661 purchase of allocated SA Murray water

Quantification approach

Data source

Water Information Licence Management and Administration (WILMA) database.

Provided by

South Australian Department of Environment Water and Natural Resources Management.


An extract from the WILMA database provided the volume of water allocated to BIL under the WAE that it owned or leased.

A WILMA database extract also provided the value of the water allocations traded–in by BIL during the 2012–13 year.

A trade (perpetual transfer) and/or lease of WAE 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 WAE trade or lease, there is no change to the allocation balance.

Allocation trades change the actual authorisations to abstract (take) water, irrespective of the number of shares owned or held on lease.

Assumptions, limitations, caveats and approximations

  • 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.
  • Only the transactions approved during the 2012–13 year are reported.
