W3 Werribee - Werribee River Terraces

This information has been developed from the publications:

  • Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) by Neville Rosengren
  • Sites of Geological and Geomorphological Significance on the Coast of Port Phillip Bay (1988) by Neville Rosengren.
  • Sites of Geological and Geomorphological Significance in the Shire of Otway (1984) by Neville Rosengren.
Geological heritage sites, including sites of geomorphological interest and volcanic heritage sites, are under regular revision by the Geological Society of Australia, especially in the assessment of significance and values. Reference should be made to the most recent reports. See the Earth Science Heritage section of the Geological Society of Australia website (external link) for details of geological heritage reports, and a bibliography.

LocationWerribee - 945995. Former Shire of Werribee. Valley of the Werribee River immediately south of the Malty By-Pass Road bridge.

W3 - Terraces of Werribee River

Access

Main Drive (Werribee Park)

Ownership

Part Crown land, part private land.

Site Description

The site includes sediments, abandoned channels and terraces of the valley of the Werribee River. Immediately south of the Malty By-Pass bridge, the river channel is bordered on the west by a narrow floodplain with flood chute scars, while behind this is an older terrace 2 to 4 m higher. To the west of the channel are cliffs in alluvium of the Werribee delta.

Opposite Werribee Park Mansion, the modern floodplain is wider and includes an abandoned meander of the river.

Significance

Local. The site illustrates stages in the development of the alluvial features of the lower Werribee River.

Management

Class 3. Although modified by the establishment of a zoological park, the main landform characteristics of the site are still evident. In future developments at the park, it would be preferable to avoid grading or building on the changes of slope at the edge of the terrace and floodplain.
