This year marks a decade since the end of the Millennium Drought, when flood waters reached the mouth of the River Murray in 2010. For 1,200 days prior, Australia’s most iconic river had ceased flowing to the sea, causing populations of fish and other aquatic animals to plummet.
However, our research has shown some clever engineering and increasing volumes of water for the environment are helping congolli and pouched lamprey to bounce back in record numbers.
With native fish in the Murray-Darling Basin just a fraction of what they were before European colonisation, rebuilding populations will be a long process. But learning from successes like this along the way will aid in the journey toward a healthier river.
