Yarra River and Port Phillip Bay Report Card


Healthy river catchments and bay environments are important to a city's liveability. The catchments and bay of the Port Phillip region are popular social and recreational areas, and are important to the livelihoods of farmers, fishers and businesses across Victoria.

Port Phillip Bay (the Bay) and its catchments are interconnected ecosystems. Land use in these catchments will impact water quality in both the waterways and the Bay. Water quality in waterways is typically best in forested areas and declines as a catchment's environment becomes increasingly urbanised.

High levels of nutrients and sediment travel from the catchments into the Bay during heavy rainfall and can contribute to algal blooms, fish deaths and the alteration of seagrass habitat.

The Yarra River and Port Phillip Bay Report Card was developed to report on the health of Port Phillip Bay and its associated catchments using water quality indicators. The Report Card provides examples of some actions undertaken by government and community that have resulted in a positive impact on water quality.

Details about the individual indicators and how they are used to form a single measure of water quality are available via the following links:
