“Updated Murray system accounts have reduced the risk of spill at Lake Hume from 85 per cent to 80 per cent,” northern Victoria resource manager Mark Bailey said on July 10.
“The risk of spill from Lake Eildon in the Goulburn system remains at 80 per cent. The risk of spill from Lake Eppalock in the Campaspe system is also unchanged at 70 per cent.”
Dr Bailey said the risk of spill assessment did not describe the chances of flooding this season.
“The risk of spill is a water accounting assessment. It does not refer to flood risks downstream of the storages.”
Trading opportunities
Allocation trade from NSW 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 Victoria’s share of both Hume and Dartmouth reservoirs below 50 per cent.
As the risk of spill from Victoria’s share of Hume and Dartmouth is currently greater than 50 per cent, allocation trade from NSW to Victoria is not possible.
The volume available for trade is updated monthly with each risk of spill announcement.
The risk of spill in the Murray, Goulburn and Campaspe systems in 2024-25 will be updated on Monday, August 12.
