Dredging

Parks Victoria is the waterway manager for the designated local ports of Port Phillip and Western Port.  Since 1998, Parks Victoria has managed an ongoing maintenance dredging program to facilitate safe boating access to local port facilities and harbours within its jurisdiction and control.  Key locations include: Queenscliff entrance, Patterson River entrance and Mordialloc Creek entrance.  Other sites include: Werribee River entrance, Portarlington Harbour, San Remo Jetty, St Kilda Pier, Tankerton Jetty and St Leonards Harbour.

The Long Term Environmental Management Plan

Following a review of the maintenance dredging program, a number of changes to design standards and methodologies were adopted as part of the new Bays Maintenance Dredging Program – Long Term Environmental Management Plan (LTEMP).  The LTEMP has now been approved, and provides a framework for Parks Victoria’s ongoing maintenance dredging program.  Implementation is expected to take between 12 and 18 months as some sites may not require any maintenance for a while.

Safe Navigation Around Dredge Vessels

When encountering a dredge vessel, mariners should always maintain a safe speed and pass on the non-obstruction side of the dredge vessel indicated by a double black diamond signal.  A double black ball signal indicates the obstruction side to avoid.  A signal with black ball, black diamond, black ball indicates the vessel is restricted in its maneuverability.
