In an effort to support native fish species in the Murrumbidgee River, two engineered log jams have been created near Tharwa.
Dr Lisa Evans says this is a good thing.
“The log jams are counteracting the build up of sand over the past century through erosion from man-made causes; this has been a major threat to the native fish of the Upper Murrumbidgee as it reduces water depth and smothers the rocky and woody habitat native fish need,” Dr Evans said.
“Since the log jams were completed in March, we have seen faster river flows and a deeper channel develop that will help fish move more freely along the river, as they used to.
“The log jams’ rocks and snags also form an important component of fish habitat as they provide fish with places to hide from predators, feeding and resting, , sites .
“By improving fish habitats, this work will boost native fish populations and foster a healthier river environment for native species,” Dr Evans said.
