EstuaryWatch is a community based, citizen science estuary monitoring program which began in 2006 through the Corangamite CMA and the Western Coastal Board. The program has now expanded to monitor the condition of 11 estuaries in the Corangamite region.

What do EstuaryWatch groups do?

Each EstuaryWatch group consists of a team of four to six volunteer who roster themselves to monitor sites each month. Each estuary differs in the length of time monitored, and the time it takes to monitor.

During a site visit EstuaryWatch volunteers use specialised equipment to collect water quality data for the portal. Groups also photograph and record details of changing water levels, vegetation condition and the status of estuary mouths (e.g. whether they are open or closed).

The information collected assists in determining estuarine health and supports estuarine managers in decision making.

11 estuaries are monitored by EstuaryWatch volunteers in the Corangamite region:
