The ability of native fish to move freely up and downstream within our rivers and wetlands is vital to their survival. Fish need to move in order to feed, find shelter and reproduce. Impeding fish passage through the construction of dams, weirs, floodgates and waterway crossings can negatively impact native fish by creating physical, hydrological or behavioural barriers that:
This project was undertaken to identify barriers to fish passage in the Namoi catchment and in doing so provide the former Catchment Management Authority (now Local Land Services) with information necessary to undertake targeted remediation works.
