Current Determination

Tuesday 15 August, 2017

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

The Murray system increases from 66 per cent to 70 per cent of high-reliability water shares (HRWS).

The Goulburn system and the Loddon system both increase from 40 per cent to 45 per cent HRWS.

The Campaspe system remains unchanged at 100 per cent HRWS.

The Broken system increases from 6 per cent to 15 per cent HRWS.

The Bullarook system increases from 32 per cent HRWS to 100 per cent HRWS plus 35 per cent of low‑reliability water shares (LRWS).

Resource Manager Mark Bailey said rainfall in early August was the main contributor to the increases in seasonal determinations.

“The rainfall in early August produced the best flows into the storages so far this winter,” Dr Bailey said.

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

“Conditions across northern Victoria are currently close to the Dry outlook scenario for seasonal determinations."

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

The seasonal determinations for northern Victorian water systems on Tuesday, August 15 are:

Water System High-Reliability Water Share Low-Reliability Water Share
Murray 70% 0%
Broken 15% 0%
Goulburn 45% 0%
Campaspe 100% 0%
Loddon 45% 0%
Bullarook 100% 35%

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 are next updated on September 11, 2017.

The Goulburn system’s inter-valley trade (IVT) account owes about 210 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.
