Victorian Water Systems Seasonal Determinations Update

Increase in Campaspe and Loddon system seasonal determinations

The Resource Manager for northern Victoria today announced an increase in 2015/16 seasonal determinations in the Campaspe and Loddon system.

The Campaspe system increases by one per cent to 65 per cent of high-reliability water shares (HRWS). The Loddon system increases by two per cent to 82 per cent HRWS.

Seasonal determinations in the Murray, Broken, Goulburn and Bullarook systems remain unchanged.

“Despite warm and dry conditions over the past fortnight, evaporation and river losses have been slightly lower than expected in the Campaspe and Loddon systems. This enabled the small seasonal determination increases to be announced today,” Resource Manager for northern Victoria Mark Bailey said.

“Inflows to the major storages remain very low.”

Trading Opportunities

The Goulburn system’s inter-valley trade (IVT) account owes about 43 GL to the Murray system on March 15. 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. There is currently about 12 GL of capacity available to trade from New South Wales to Victoria.

Customers participating in the water trading market can monitor trade availability on the Water Register website.

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 158 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.
