2022/23 Risk of Spill announcements

10 November 2022 - 2022/23 Risk of Spill update for Murray, Goulburn and Campaspe systems

The Resource Manager for northern Victoria today released updated 2022/23 risk of spill information for each of the Murray, Goulburn and Campaspe systems.

Resource Manager Dr Mark Bailey said ongoing wet conditions through October caused deductions from spillable water accounts in the Murray, Goulburn and Campaspe systems.

“Flows into Lake Eildon and Lake Eppalock during October were the highest on record and both storages spilled significant volumes,” Dr Bailey said.

Releases from Lake Hume to manage water levels continued throughout October and into November.

“The Eildon and Hume releases will cause deductions from Goulburn and Murray spillable water accounts respectively. The quantities of spill will be confirmed in the November 15 seasonal determination announcement,” Dr Bailey said.

“There are no volumes to deduct from spillable accounts in the Campaspe system because all entitlements received the maximum available seasonal determination on October 17,” Dr Bailey added.

Dr Bailey said the assessments did not describe the chances of flooding. “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 New South Wales to Victoria is not possible currently because Victoria’s shares of Lake Hume and Dartmouth Reservoir are full.

 The opportunity for allocation trade is updated with each risk of spill announcement. Customers can learn more about trade opportunities on the  Victorian Water Register website.

10 October 2022 - 2022/23 Risk of Spill update for Murray, Goulburn and Campaspe systems

The Resource Manager for northern Victoria today released updated 2022/23 risk of spill information for each of the Murray, Goulburn and Campaspe systems.

Resource Manager Dr Mark Bailey said very wet conditions during September had increased the risk of spill in Campaspe system while the risk in the Murray and Goulburn systems remained unchanged.

“Flows into Lake Eppalock during September were well above average and the storage began to spill in late September,” Dr Bailey said.

Releases from Lake Hume and Lake Eildon to manage water levels also occurred throughout September and into October.

“The Eildon and Eppalock releases will cause deductions from Goulburn and Campaspe spillable water accounts respectively. The quantity will be confirmed in the October 17 seasonal determination announcement,” Dr Bailey said.

“Deductions from Murray spillable water accounts will occur if low-reliability water share seasonal determinations increase and allocation is transferred into these accounts,” Dr Bailey noted.

Dr Bailey said the assessments 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 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 from Victoria’s share of both Lake Hume and Dartmouth Reservoir below 50 per cent.

Presently, allocation trade from New South Wales to Victoria is not possible because Victoria’s shares of Lake Hume and Dartmouth Reservoir are full.

The opportunity for allocation trade is updated with each risk of spill announcement. Customers can learn more about trade opportunities on the Victorian Water Register website.

12 September 2022 - 2022/23 Risk of Spill update for Murray, Goulburn and Campaspe systems

The Resource Manager for northern Victoria today released updated 2022/23 risk of spill information for each of the Murray, Goulburn and Campaspe systems.

Resource Manager Dr Mark Bailey said storage inflows boosted by rainfall during August had increased the risk of spill in Goulburn and Campaspe systems.

“Flows into Lake Eildon and Lake Eppalock during August were well above average,” Dr Bailey said. “The volume in Lake Eildon quickly climbed above 90 per cent of capacity and Goulburn-Murray Water started releases in late August to control the rate of rise. The releases are continuing.”

Releases from Lake Hume to manage water levels also occurred throughout August and into September.

“The Eildon and Hume releases will cause deductions from Goulburn and Murray spillable water accounts respectively. The quantity will be confirmed in the September 15 seasonal determination announcement,” Dr Bailey said.

“The risk of spill from Lake Eppalock in the Campaspe system has increased to about 40 per cent,” Dr Bailey said. “Lake Eppalock is currently about three-quarters full.”

10 August 2022 - 2022/23 Risk of Spill update for Murray, Goulburn and Campaspe systems

The Resource Manager for northern Victoria today announced updated 2022/23 risk of spill information for each of the Murray, Goulburn and Campaspe systems.

Resource Manager Dr Mark Bailey said ongoing releases to manage storage levels at Lake Hume led this month’s update.

“Releases from Lake Hume to control the storage volume occurred throughout July and have continued into August,” Dr Bailey said.

“These releases will cause deductions from Murray rules‑based entitlements initially and then from spillable water accounts.

“The impact on the spillable water accounts will be described in the August 15 seasonal determination announcement,” Dr Bailey said.

“The risk of spill has reduced in the Goulburn and Campaspe systems after both catchments recorded below-average rainfall and storage inflows during July,” Dr Bailey said.

“The risk of spill from Lake Eildon in the Goulburn system is about 65 per cent and the risk of spill from Lake Eppalock in the Campaspe system is about 15 per cent.”

Dr Bailey said the assessments 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.”
