Adelaide
4.2 Irrigation scheme inter-region claim on water

Supporting information

During the 2011–12 year, Barossa Infrastructure Limited (BIL) was the only irrigation scheme in the Adelaide region that transferred–in water from outside the region. It comprised River Murray water allocated under water access entitlements (WAE) owned or leased by BIL, water allocations purchased on the water market and other contracts made with other WAE holders. River Murray water was transferred to BIL via SA Water infrastructure.

The value reported (0 ML) is the volume of water permitted to be carried over at 30 June 2012 into the next year. It is detailed further per state jurisdiction from which water is claimed.

SA Murray

During the 2011–12 year, BIL owned and leased Class 3a WAEs to the River Murray consumptive pool for South Australia, for irrigation purposes. BIL also has a long-term agreement with Summit Water Holdings Pty Ltd (Summit Water) to trade water allocations for the River Murray consumptive pool. The following table details these WAE.

The volume of Class 3a WAE owned or held on lease by BIL at 1 July 2011 (4,362 ML) is different from the volume reported at 30 June 2011 in the 2011 Account, which was 4,396 ML (see note of line item 12.12 Increase of irrigation scheme inter-region claim on water  in the 2011 Account). This is due to two WAE leases held by BIL expiring on 30 June 2011.

Of the total Class 3a WAE reported in the table above, 1,543 ML was owned by BIL (source: BIL); that volume did not change during the 2011–12 year.

During the 2011–12 year, Class 3a WAE held on lease by BIL increased by 6 ML due to a long term lease contracted from one of its customers in the Barossa Valley (see line item 12.12 'Increase of irrigation scheme inter-region claim on water').

More details of the Class 3a water access entitlement can be found in the water allocation plan for the River Murray Prescribed Watercourse

At the end of the 2011–12 year, carry-over of un–abstracted SA Murray water was not permitted as the temporary carry-over arrangements that were provided as an annual contingency during the drought ceased on 30 June 2011. Therefore, the claim under this type of WAE was 0 ML at 30 June 2012.

NSW Murray

During the 2011–12 year, BIL had a long-term agreement with Summit Water Holdings Pty Ltd to trade yearly water allocation announced on a 867 ML high security WAE owned by that company. There was no claim remaining at 30 June 2012.

Victorian Murray

During the 2011–12 year, BIL did not hold any WAE on the Victorian Murray. It traded–in 950 ML of water allocated on a VIC Murray WAE owned by a Victorian irrigator during the 2011–12 year though. There was no carry-over volume at 30 June 2012.

Method

On 1 July 2011, the South Australian Minister for Sustainability, Environment and Conservation announced in the South Australian Government Gazette that River Murray allocations would be 100% of the nominal maximum water allocation for the 2011–12 year. Temporary carry-over arrangements that were provided as an annual contingency during the drought ceased on 30 June 2011. These arrangements remained in force during the 2011–12 year. Therefore the volume of water permitted to be carried over was 0 ML.
