On 2 November, HRWS allocations increased from 86% to 95% on the Murray system; and from 10% to 20% allocation for LRWS on the Broken system. The Murray system HRWS allocation reached 100% at the second announcement on 15 November, while the Broken LRWS allocation was increased to 40%.
All systems have now reached 100% allocations for HRWS, and there are full LRWS allocations for the Campaspe and Bullarook Creek systems. G-MW’s next allocation announcement will be made on 15 December.
On 10 November, the Northern Victoria Resource Manager re-confirmed that the risk of spill in the Goulburn and Campaspe systems remains high, therefore, at this stage water held in spillable water accounts cannot be made available to customers. The next risk of spill announcement will be made on 12 December.
Wimmera Mallee Supply System
The Wimmera Irrigation Association is continuing to negotiate a sale of the irrigation entitlement to the Commonwealth Government, and irrigation channel runs are deferred until the outcome of the sale is known. GWMWater has not delivered irrigation supplies for around 10 years.

Werribee Basin
SRW’s share of the Werribee storages was at 90% of capacity at the end of November.
