Water Quality

In 2018 we commissioned a report into the water quality of the Werribee River Catchment. It found that our waterways have been highly modified and impacts from intensive agriculture and urbanisation have affected water quality. This is due to  excessive sediments and nutrients entering into the river and its tributaries. The extraction of water from the catchment has also led to its degradation. The report stated that conditions for the river vary from ‘very good’ in the upper and less developed areas of the river, through to ‘moderate’ to ‘very poor’ in the lower and highly developed regions. 

The report confirmed that with the ongoing, and rapid, urbanisation of the Werribee River Catchment, it is important that we continue to collaborate with stakeholders and local communities, to ensure the waterways are adequately managed, monitored and regenerated. The health of our growing community depends upon it. 


A monthly citizen science program for monitoring waterway health. We have collected monthly water quality data from Bungees Hole since 2008 and will begin soon at an additional site in Werribee South. For more information and to join the team, please email us at admin@werribeeriver.org.au

Bio2Lab Sensors

As part of our Progressing Platypus project, we worked with Bio2Lab to install water and stormwater quality sensors at Cobbledicks Ford, Health's Rd, Lock Ave and Tesron Court. We will shortly release the project report, including a summary of the data from the program over the 12 months. Later in 2023, we will be installing two sensors in Werribee South, monitoring sediment run off from the market gardens as part of our Save Our Soils project.
