Living Streams approach – Lower Vasse River
The City of Busselton is developing a Living Streams approach for the Lower Vasse River. The project will involve altering the morphology of the Lower Vasse River to restore ecological processes and create physical conditions that provide greater resilience to high nutrient conditions.

Owing to increased inputs of nutrients from catchment sources, and the still conditions created by impoundment, the Lower Vasse River is eutrophic. Extremely high nutrient concentrations, particularly phosphorus, and ideal physical conditions drive severe seasonal algal blooms for up to seven months from November to May. Algal blooms cause unsightly water discoloration and scums and unpleasant odours. These blooms are often dominated by blue-green algae (cyanobacteria) which are potentially toxic and close the waters to public use.

The Wharf Street Wetland and Civic Centre Parklands intercept and treat stormwater (and groundwater) from the Wharf Street main drain, located in the greater Canning Plain Catchment – a priority catchment with high nutrient loads. The wetland was designed by Syrinx to remove nutrients and other pollutants from stormwater before it flows into the Canning River.
