Habitat and fish protected by weir

More often than not, weirs are targeted for removal or for fishways because they impede fish movement, but the Murray CMA had to do
the opposite for fish in Coppabella Creek, a tributary of the Upper Murray. This creek was home to one of the few sites in the catchment
of the Southern Pygmy Perch a threatened species. With advice from NSW DPI a 50 year old weir on the creek, damaged during the floods of 2010‐11 was reinstated to remain an effective barrier to the movement of alien fish including Carp, Redfin and Gambusia. Fortunately the repairs were made before any alien fish made it upstream. For more information, contact Trish Bowen, Murray CMA, on 02 6051 2203.
