The Resource Manager for northern Victoria today updated the 2024/25 seasonal determinations.
The Campaspe system seasonal determination increases from 47 per cent of low-reliability water shares (LRWS) to 48 per cent LRWS, in addition to 100 per cent of high-reliability water shares (HRWS).
The Bullarook system seasonal determination increases from 7 per cent HRWS to 12 per cent HRWS.
Seasonal determinations in the Murray, Goulburn and Loddon systems are unchanged at 100 per cent HRWS.
In the Broken system, seasonal determinations remain at 100 per cent HRWS and 100 per cent LRWS.
Resource Manager Andrew Shields said recent rainfall provided the resource for the small water availability improvement.
“Rainfall at Lake Eppalock and the Bullarook storages since the last assessment meant the evaporation losses were lower than our estimates,” Mr Shields said. “This increased the amount of water available for allocation in the Campaspe and Bullarook systems.”
The seasonal determinations for northern Victorian water systems on Wednesday, 15 January are:
Outlook for the 2024/25 Season
The Bullarook seasonal determination outlook for 2024/25 is based on historical flow records that have been adjusted to match climate conditions observed since 1975. The outlook scenarios presented are:
- Wet Inflow volumes to major storages that are greater in 10 years out of 100
- Average Inflow volumes to major storages that are greater in 50 years out of 100
- Dry Inflow volumes to major storages that are greater in 90 years out of 100
- Extreme Dry Inflow volumes to major storages that are greater in 99 years out of 100
The following table summarises possible high-reliability water share seasonal determinations through the season and include a reference year to help users recognise the possible inflow conditions.

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 Victoria’s share of 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.
