Opening surge barrier will flush estuary

Busselton Dunsborough Times

The Vasse estuary surge barrier will be opened to the ocean on Monday to increase water flushing as part of a plan to reduce major algal blooms.

The gate-opening strategy follows a three-year scientific trial by the Department of Water and Environmental Regulation, which found opening the gates during the summer provided the most benefit to water quality. The trial also led to the recommendation that the culvert between Station Gully and Toby Inlet remain open.

City of Busselton senior sustainability and environment officer Mathilde Breton said the opening of the Toby Inlet to the ocean would have immediate and positive effects on water quality.

She said the strategy aimed to prevent deteriorating water quality in the inlet and unpleasant odours throughout summer.

GeoCatch chairman Chris Adams said the organisation were supportive of the science undertaken in the Toby Inlet as part of the Revitalising Geographe Waterways initiative.
