Resource manager Mark Bailey said the risk of spill had declined in all three systems.
“Below average flows into the major storages during July continued the trend of recent months,” Dr Bailey said.
“When combined with water released to meet downstream demand, the risk of spill at Lake Hume, Lake Eildon and Lake Eppalock has reduced.
“The risk of spill from Victoria’s share of Lake Hume in the Murray system was 75 per cent and at Lake Eildon in the Goulburn system the risk was 60 per cent.
“The risk of spill at Lake Eppalock in the Campaspe system was 65 per cent.”
Dr Bailey said the risk of spill was a water accounting assessment and did not describe flood risks or the chances of flooding this season.
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 next announcement will be on September 10.
