The City of Busselton has engaged Alluvium Consulting Australia Pty Ltd to develop living stream designs for the Lower Vasse River.
The intention behind this approach is to create conditions less favourable to algal blooms in the river.
This may involve removing sediment, revegetation works, changes to the river's shape and the creation of a diversity of habitats.
Water treatment options may also considered.
The project is partly funded through the Revitalising Geographe Waterways 2 Program and is a recommendation from the Lower Vasse River Waterway Management Plan (2019).
Mayor Grant Henley said that no single solution will individually resolve the algal bloom issue in the Lower Vasse River and that a package of interventions is required to make a difference.
"This project intends to combine all the latest science and research with what the community values and wants to see in the river," he said.

An online survey is now available for the community to contribute their views towards the project's objectives and potential works.
The survey is available at yoursay.busselton.wa.gov.au/ until September 15, 2020.
Conceptual plans will be available for public feedback next month and an information session is planned for September 16, 2020 prior to finalising the designs.
The Lower Vasse River Management Advisory Group will also provide input to the development of the detailed designs.
To register for the information session, please contact Mathilde.breton@busselton.wa.gov.au
