The outlooks for 2020/21 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 tables summarise possible high-reliability water share seasonal determinations through the season and include a reference year to help users recognise the possible inflow conditions.

Additional outlook scenarios for each system are available from the Northern Victorian Resource Manager website (www.nvrm.net.au/outlooks).
Outlooks for low-reliability water shares (LRWS) will be prepared during the 2020/21 season if seasonal determination are 100% HRWS and there is the possibility of LRWS being allocated.
