WATER bugs and plants that provide food and shelter for native fish and other aquatic animals will benefit from an environmental flow currently being delivered along the Goulburn River.
Goulburn Broken Catchment Management Authority Environmental Water project co-ordinator, Daniel Lovell said, “As much of the rain and run-off into the Goulburn River is now captured in the dams and used to supply towns, industry and farms, the amount of water flowing down the river in winter and spring has reduced. It also means the river flows higher and faster in the hotter months of the year when communities require more water, which is the opposite of what would happen if there were no dams and weirs.
“These changes have affected the health and survival of native plants and animals, so we’re giving nature a helping hand and delivering environmental water at this time of the year to mimic more natural flow conditions.”
The increased flows are planned to reach a maximum of 9,500ML/day (river height 4.30m) at Murchison by June 28. These flows are well below minor flood level.
In the event of heavy rain, the timing and size of the environmental flow could change or not go ahead at all.
The environmental flow will also help bank-stabilising plant growth on the lower banks of the Goulburn River and improve water quality.
