Victoria risk of spill: September 10th

10 September 2020 – 2020/21 Risk of Spill update for Murray and Campaspe systems

Resource Manager for northern Victoria Mark Bailey said today the risk of spill in the Murray and Campaspe systems during 2020/21 had reduced, but remained above the 10 per cent threshold needed to declare a low risk of spill.

“The risk of spill from Lake Hume in the Murray system during 2020/21 has fallen to about 25 per cent,” Dr Bailey said.

“In the Campaspe system, the risk of spill from Lake Eppalock is 12 per cent.”

The risks of spill decreased despite both storages holding more water since the August assessment.

“While the improved storage volumes are welcome, the slow rate of filling and the passage of time meant the risks of spill decreased,” Dr Bailey said.

“The risks of spill will continue to decline if rainfall remains sparse in the Murray and Campaspe catchments.”

Dr Bailey said the risk of spill assessment did not describe the chances of flooding in the Murray 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.

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 Victoria’s share of the both Hume and Dartmouth reservoirs below 50 per cent. 

The current risk of spill in the Murray system allows 200 GL of net trade from New South Wales to Victoria. Customers can find out more about trade adjustments on the Victorian Water Register website.
