21.1 Surface water allocation announcements
Supporting information
The volume recognised in the water accounting statements (20,761 ML) represents the volume of water allocated in the Bacchus Marsh Irrigation District, Werribee River and Werribee Irrigation District during the 2011–12 year.
Allocations are made according to Southern Rural Water's Werribee and Bacchus Marsh Allocation Method. Allocations are reviewed fortnightly and low reliability water shares do not receive an allocation announcement until high reliability shares reach 100%.
Allocations are made for high reliability and low reliability water shares. In addition there are a small number of entitlements that are in the process of being converted to water shares. For these entitlements a supply by agreement arrangement is in place.
