Environmental flows delivered in the Goulburn and Campaspe rivers during October aimed to help re-establish native vegetation on the lower river banks and improve water bug populations that native fish feed on.
Over 100 GL was delivered in the Goulburn event and 14 GL in the Campaspe event.
Recent monitoring found the Goulburn release also triggered Golden perch (yellowbelly) breeding, which was an unexpected but welcomed benefit.
The flows use a combination of Commonwealth and Living Murray environmental water, are planned by the Goulburn Broken CMA (Goulburn River) and North Central CMA (Campaspe River) and managed by Goulburn-Murray Water.
A second spring environmental flow release is planned for the Goulburn for mid-November to further stimulate Golden perch breeding.
Environmental water is set aside as an entitlement in the same way as water is set aside in entitlements for irrigation and urban water use.
The Victorian Environmental Water Holder prioritised these water releases as part of its Seasonal Watering Plan 2014-15.
