A wet start
2021 and 2022 have seen high inflows from the northern Murray-Darling Basin via the Barwon-Darling (Baawan-Baaka) into the Menindee Lakes. To manage lake levels and flood risks, large volumes of water have been released by river operators down both the lower Darling-Baaka River and the Great Darling Anabranch.
In the lower Darling-Baaka River, these releases have provided the largest overbank flows in more than 10 years. This has:
- connected the river channel with many of the wetlands and billabongs of the lower Darling-Baaka River floodplain, providing significant benefits for vegetation, waterbirds, aquatic bugs, frogs and other animals that live on the floodplain.
- assisted dispersal of Golden perch (aka Yellowbelly or Callop) from the northern Basin and Menindee Lakes to the lower Darling-Baaka River and ultimately into the River Murray.
- provided a boost in river productivity which in turn generates plenty of food for juvenile fish.
Keep up to date with use of water for the environment, monitoring activities and outcomes via our event updates.
Of particular interest, fish movement tracking is underway, with 350 Golden perch tagged in the Menindee Lakes and River Murray so far, and more to come: Supporting native fish in the Murray Darling Basin. Strategically placed receivers along the lower Darling-Baaka, Anabranch and Murray River will allow scientists to track the movements of the fish.
