Outlook for the 2017/18 season

Monday 16 October, 2017

The Resource Manager uses historical flow records to assess the seasonal determinations for a range of inflows to the major storages. The scenarios 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.

Seasonal determinations under additional scenarios for each system are available from the Northern Victorian Resource Manager website at www.nvrm.net.au/outlooks.

An outlook for the Murray system is not provided because of the high likelihood of reaching 100 per cent HRWS this season.
