Bioregions within the Catchment


Description: The Werribee River catchment has three main bioregions of note. The river’s headwaters begin in the Wombat Forest, part of the Central Victorian Uplands. The river is joined by other tributaries just south of Bacchus Marsh, where the river has cut its way down onto the Victorian Volcanic Plain and formed gorges. As the river approaches Werribee, it flows over an old delta, and winds its way into Port Phillip Bay across the Otway Plain.
