Outlook for the 2023/24 Season
The outlooks for 2023/24 seasonal determinations are 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 Broken high-reliability water share seasonal determinations through the season and include a reference year to help users recognise the possible inflow conditions.

“The shortfall to announcing seasonal determinations for low-reliability water shares in the Goulburn and Loddon systems is about 165 gigalitres,” Dr Bailey said. “The shortfall in the Murray system will be confirmed after the annual borrow from the Barmah-Millewa Environmental Water Allocation is fully repaid. The repayment will begin now that the Murray has reached 100 per cent HRWS.”
Upcoming Resource Manager Announcements
- The next 2023/24 seasonal determination announcement will be released on Friday September 1, 2023.
- The risk of spill in the Murray, Goulburn and Campaspe systems will be updated on Monday September 11, 2023.
