Low risk of spill declared in the Goulburn system
Resource Manager for northern Victoria Mark Bailey today declared a low risk of spill in the Goulburn system.
The risk of spill in the Murray and Campaspe systems during 2017/18 remained above the 10 per cent threshold needed to declare a low risk of spill.
“Despite recent rainfall and an increase in the Lake Eildon volume, the risk of spill in the Goulburn system during 2017/18 has fallen below 10 per cent,” said Dr Bailey.
“Water in spillable water accounts in the Goulburn system will be made available for use or trade.
“Victoria’s share of the volume in Lake Hume gives the Murray system a 63 per cent risk of spill,” Dr Bailey said.
“The risk of spill from Lake Eppalock in the Campaspe system is about 34 per cent.
“Water in spillable water accounts remains quarantined in the Murray and Campaspe systems.”
Dr Bailey said the risk of spill assessment did not describe the chances of flooding in the Murray, Goulburn or Campaspe systems this season.
“The risk of spill is a water accounting assessment,” Dr Bailey said. “It does not refer to flood risks downstream of the storages.”
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.
Trade from New South Wales to Victoria is currently limited to the volume traded from Victoria to New South Wales because the risk of spill in the Murray system is above 50 per cent.
Customers participating in the water trading market can monitor trade availability on the Victorian Water Register website.

The risk of spill in the Murray and Campaspe systems will be updated on Monday September 11, 2017.
