    The Helena River is a major tributary of the Swan River. It also provides an important refuge for freshwater fish in the Perth Metropolitan Region, as it is one of few rivers that flow all year round.

    With the help of funding from the State NRM Program, the East Metropolitan Regional Council conducted a study to determine the diversity and distribution of native freshwater fish in the Helena River and its tributaries.

    Relations between habitats and species and between water quality and species were analysed, and the status of exotic fish species determined. The study also identified environmental flow requirements for freshwater fish.

    The council and the Swan River Trust used the findings to develop strategies to increase fish habitat along the river and to make recommendations for dealing with introduced fish.
