Seasonal determination update for 2017/18

Monday 17 July, 2017

The Resource Manager for northern Victoria today announced an update to the 2017/18 seasonal determinations.

The Murray system remains unchanged at 66 per cent high-reliability water shares (HRWS).

The Goulburn system and Loddon system remain at 36 per cent HRWS.

The Campaspe system remains at 100 per cent HRWS.

The Broken system increases from 1 per cent to 3 per cent HRWS and the Bullarook system increases from zero per cent to 16 per cent HRWS.

Resource Manager Mark Bailey said recent rainfall enabled the small increases to the seasonal determinations to the Broken and Bullarook systems.

“The catchments are starting to respond to rain after the very dry conditions in May and June,” Dr Bailey said.

“However, the flows into the major storages are still well below average.

“The flows are close to those that would be expected under our Dry to Very Dry scenario.".

Dr Bailey advised entitlement holders to use the seasonal determination outlooks and weather information to plan their water needs in 2017/18.

Trading Opportunities

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. As the risk of spill in the Murray system is above 50 per cent, trade from New South Wales to Victoria is limited to the volume traded from Victoria to New South Wales.

Trading opportunities from New South Wales to Victoria are next updated on August 10, 2017.

The Goulburn system’s inter-valley trade (IVT) account owes about 200 GL to the Murray system. 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.

Customers participating in the water trading market can monitor trade availability on the Water Register website. Additional information about how trade opportunities are calculated has recently been added to the allocation trading page.

The Murray-Darling Basin Authority (MDBA) has announced that trading of water allocations from above the Barmah Choke to downstream of the Choke is restricted to protect the delivery of downstream water entitlements. Customers can monitor trading opportunities across the Barmah Choke on the MDBA website.
