Lindsay Island and particularly the Mullaroo Creek has long been a prime Murray cod habitat. With the new Mullaroo fishway and regulator the ability to manage water for the environment through the Mullaroo is improving native fish feeding, breeding and movement outcomes. Over 180 young Murray cod were sampled in 2019.


First Nations engagement is being built into all projects and site managers continue to invest in the development of sustained relationships and partnerships. This includes tours to allow Traditional Owners to see fish monitoring results and supporting activities on country to allow Elders to transfer knowledge to the next generation.


River red gum trees are in the best condition since monitoring began in 2008. Black box and river red gum trees are producing new foliage and flower buds where water for the environment can be delivered.


Lake Wallawalla is a haven for waterbirds in a drying landscape. Large numbers of waterbirds were observed at the lake in spring 2018 including 500 red avocets, 195 pink-eared ducks and over 400 teal ducks.


Freshwater catfish movement between the lower Lindsay River and the River Murray has increased since the operation of the Mullaroo Creek inlet regulator and fishway.

Each year, water is released into the environment depending on the climatic conditions. See the outcomes of water over time for a long-term view of how natural and released water affects the health of rivers.
