Helping bank-stabilising plant growth, improving water quality and providing food and shelter for waterbugs and native fish were the main reasons for environmental flows occurring in the Goulburn River since September.
The flow was delivered from Goulburn Weir from mid-September and reached the Murray River a fortnight ago, with the flow peaking at 7800Ml/day at Murchison, lower than the ordered peak of 8500Ml/day.
‘‘Rainfall and high irrigation demand meant that Goulburn-Murray Water couldn’t deliver the full fresh,’’ Goulburn Broken Catchment Management Authority’s Daniel Lovell said.
He said the event used about 92Gl, which meets downstream environmental requirements (for example, water for the Hattah Lakes near Mildura).
‘‘The spring fresh went well.
‘‘It’s too early to tell how the environment reacted to the fresh but monitoring is occurring and we will have results over the next few months.’’
The next proposed flow is set down for mid-November.
