The Adjungbilly Creek in the Upper Riverina Highlands is home to one of 4 remaining populations of the endangered Macquarie Perch. Over the past 10 years with the help of DPI Fisheries and Charles Sturt University we have been monitoring the population of 'Maccas' using electrofishing and fyke net methods.
There are of course disadvantages in these methods with the percentage of fish captured influenced by factors such as the size of the fish, conductivity and flow rates.
Recently we trialled a fairly cost effective method of spotlighting. With the help from traditional owners from the Brungle Tumut Local Aboriginal Land Council, 2 sites on the Adjungbilly were surveyed. A total of 6 Maccas were identified including young of year.

We lacked information on the aquatic wildlife of the Upper Billabong catchment, so using Citizen Science - the Refreshing Rivers iNaturalist project and eDNA tests, we have gathered 1,672 observations across the catchment and also completed 9 eDNA profiles in local waterways.

Courtesy of the Refreshing Upper Billabong project, we have a limited number of tubestock suitable for planting both instream and along creek banks to reduce erosion and create habitat.

Extreme low flows are pushing refuge pools to their limits. Heat, sediment, salinity and stock impacts are degrading water quality and threatening native fish. This article outlines what’s causing it and practical steps we can take to protect our waterways.
