Further Information

Irrigators in the Campaspe system will start the 2014/15 season with 100 per cent of high-reliability water shares (HRWS).

Seasonal Determinations

The first seasonal determination announcement was made today by the Resource Manager for northern Victoria, who also announced the Murray system would start the 2014/15 season with 57 per cent HRWS and the Goulburn and Loddon systems would both start the season with 74 per cent HRWS.

Resource Manager Mark Bailey said the Broken system would start on 15 per cent HRWS and Bullarook on zero per cent HRWS.

"This is the fourth consecutive season that the Murray, Goulburn, Campaspe and Loddon systems have received a seasonal determination at the opening announcement, "Dr Bailey said.

"It is the first season since 2012/13 that the Broken system has received a seasonal determination on July 1. Seasonal determinations in the Bullarook system are not yet possible, but the volumes carried over can be delivered."

“There will be about 450,000 ML carried over in each of the Murray and Goulburn systems and about 30,000 ML in the Campaspe system."

“Dr Bailey said about 250,000 ML and 350,000 ML were expected to be held by private water share holders, including irrigators, in the Murray and Goulburn systems respectively.

"The remaining volume will be held by the environmental water holders and urban water corporations, "he said.

"These volumes will be confirmed in the next announcement."

Trading Opportunities

Allocation trade from New South Wales (NSW) to Victoria is limited to a net annual volume of 200 GL, or the volume that keeps the risk of spill in the Murray system below 50 per cent, whichever is the lesser. The probability of spill in the Victorian Murray system is greater than 50 per cent, so trade into Victoria from NSW would be limited to the volume of trade out of Victoria to NSW.

The availability of trade from NSW into the Victorian Murray system will be recalculated on July 10 and the 10th of each month thereafter.

The volume owed to the Murray system from the Goulburn system’s inter-valley trade account is about 140 GL. Trade from the Goulburn, Campaspe and Loddon systems to the Victorian Murray, or to NSW and South Australia, is allowed while the total volume owed to the Murray is less than 200 GL.

Customers participating in the water trading market can monitor trade availability on the Water Register website from about 4 July 2014.

Customers participating in the water trading market are advised that the Murray-Darling Basin Authority has announced that the trading of water allocations from above the Barmah Choke to downstream of the choke will continue in the 2014/15 water year. The Murray-Darling Basin Authority will regularly review the ability to trade across the Barmah Choke and may lift the relaxation at any time during the season.

Next Upcoming Resource Manager Announcements
