Outlook for the 2015/16 season

“Inflows into the Murray, Goulburn, Broken, Loddon and Campaspe systems during October were close to the ‘Extreme Dry’ category,” said Dr Bailey.

The full inflow record was used to assess seasonal determinations for a range of inflow scenarios. The scenarios for different inflow conditions were produced using the following terminology:

Wet: Inflow volumes that have 10 chances in 100 (or one chance in 10) of being exceeded.

Average: Inflow volumes that have 50 chances in 100 (or five chances in 10) of being exceeded.

Dry: Inflow volumes that have 90 chances in 100 (or nine chances in 10) of being exceeded.

Extreme Dry: Inflow volumes that have 99 chances in 100 (or 9.9 chances in 10) of being exceeded.

The following tables summarise possible HRWS seasonal determinations in the Murray, Goulburn, Loddon, Campaspe and Broken systems through the 2015/16 season.

2015/16 Low-Reliability Water Share Outlooks

Details about the chances for seasonal determinations of low-reliability water shares will be included when seasonal determinations reach 100 per cent of high-reliability water shares.

Trading Opportunities

The Goulburn system’s inter-valley trade (IVT) account owes about 95 GL to the Murray system on November 16. The Goulburn, Campaspe and Loddon systems can trade to the Victorian Murray system, New South Wales and South Australia while the total volume owed to the Murray system is less than 200 GL.

The Goulburn, Campaspe and Loddon systems can trade from the Victorian Murray system, New South Wales and South Australia while the total volume owed to the Murray system is greater than zero.

Allocation trade from New South Wales to Victoria is limited to the lesser of a net annual volume of 200 GL or a volume that keeps the risk of spill in the Murray system below 50 per cent. The spill risk limit allows more than 200 GL of trade, and so the net annual volume of 200 GL applies unless advised otherwise.

Customers participating in the water trading market can monitor trade availability on the Water Register website, waterregister.vic.gov.au/water-trading/allocation-trading.

Standard Murray-Darling Basin Authority policy prohibits the net trade of allocations from above the Barmah Choke to downstream to protect delivery of downstream water entitlements. However, there is currently about 165 GL of capacity available to trade from upstream to downstream. Customers can monitor trading opportunities across the Barmah Choke on the Murray-Darling Basin Authority website at www.mdba.gov.au/river-data/barmah-choke.
