“Most of the northern Victorian systems have tracked between the ‘Average’ and ‘Dry’ outlook categories in recent months,” Dr Mark Bailey said. “Continued rainfall is needed to maintain the better inflows rates observed during May and June 2016.”
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.
Murray System Outlook for Seasonal Determination of High-Reliability Water Shares
Goulburn System Outlook for Seasonal Determination of High-Reliability Water Shares
Campaspe System Outlook for Seasonal Determination of High-Reliability Water Shares
Loddon System Outlook for Seasonal Determination of High-Reliability Water Shares
Broken System Outlook for Seasonal Determination of High-Reliability Water Shares
Bullarook System Outlook for Seasonal Determination of High-Reliability Water Shares
Seasonal determinations under additional scenarios for each system are available from the Northern Victorian Resource Manager website. The website also has outlooks based only on inflows similar to those received from April to June this year. These ‘tercile’ outlooks use only 40 of the 120 years of records available and indicate possible seasonal determinations arising from similar recent conditions instead of all possible outcomes.
