On Monday the 10th of September the Resource Manager for northern Victoria, Mark Bailey declared a low risk of spill in the Goulburn and Campaspe systems.
The risk of spill in the Murray system during 2018/19 remained above the 10 per cent threshold needed to declare a low risk of spill, therefore the Murray risk of spill still has not been declared.
“Despite August rainfall increasing the volumes in Lake Eildon and Lake Eppalock volumes, the risk of spill in the Goulburn and Campaspe systems during 2018/19 has fallen below 10 per cent,” Dr Bailey said.
“Water in spillable water accounts in the Goulburn and Campaspe systems will be made available for use or trade.”
“Victoria’s share of the volume in Lake Hume gives the Murray system a 29 per cent risk of spill.”
“Water in spillable water accounts in the Murray system remains quarantined from use or trade.””
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. It does not refer to flood risks downstream of the storages,” Dr Bailey said.
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 current risk of spill limit allows 200 GL of net trade from New South Wales to Victoria.
Customers participating in the water trading market can monitor trade availability on the Victorian Water Register website.
