Declaration of low risk of spill for the Murray System

A low risk of spill was today declared in the Murray system by the Resource Manager for northern Victoria.

Resource Manager for northern Victoria Mark Bailey said the risk of spill in the Murray system during 2015/16 had fallen below the 10 per cent threshold for a declaration to be made.

"Based on Victoria's share of the volume held in Lake Hume, the risk of spill is currently about 5 per cent," Dr Bailey said. "The water held in spillable water accounts in the Murray system will now be made available to entitlement holders for use or trade".

Dr Bailey added the risk of spill assessment did not refer to the chances of flooding in the Murray system. He reminded the public that the risk of spill relates to the availability of water in spillable water accounts and does not refer to flood risks downstream of the storages.

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. The spill risk limit allows more than 200 GL of trade. Therefore, the net annual volume of 200 GL will apply unless advised otherwise.

Customers participating in the water trading market can monitor trade availability on the Water Register website, waterregister.vic.gov.au/water-trading/allocation-trading.

Next announcement on risk of spill

The first risk of spill assessment in the Murray, Goulburn and Campaspe systems for the 2016/17 season will be announced on July 1, 2016.
