Waterbug census

Children looking at waterbug samples

Waterbugs let us know how healthy our water is, and you can too. By joining the Waterbug Census and monitoring your local macroinvertebrates, you’ll help us check the health of our rivers and creeks.

COVID-19 update

Waterwatch workshops and events will continue to be held online where possible. When deemed safe to resume, face-to-face activities will be held in a COVID-safe manner. Check out our ‘Expert Connections’ webinar series on ecological and waterway themes, and Melbourne Water’s social media for updates and events.

Before starting any activity, contact your program manager for advice on specific safety requirements and to receive a copy of our COVID-19 Control Plan.

What’s involved

Waterbug monitoring takes place in autumn and spring at specific sites across Melbourne. Volunteers who want to participate in this program receive free training to learn water sampling and identification skills.  

This citizen science program involves learning how to:

  1. Collect a sample of waterbugs from your local waterway
  2. Pour them into viewing trays and sort the different bugs
  3. Identify each bug type and record it on your data sheet.

Data collection and use

Waterbug data is collected using the Agreed Level Taxonomy method, which ensures data quality and consistency across monitoring sites. The information supports ongoing research and helps us track waterway health — as well contributing to national biodiversity records through the Atlas of Living Australia.
