Maintenance Dredging Program

Victorian Waterways

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.

A recent review of the maintenance dredging program was undertaken, and following an examination of the program’s marine design standards and methodologies, a number of changes have been recommended.

The Long Term Environmental Management Plan

These changes, and the manner in which the maintenance dredging program will be delivered into the future, have been compiled into a report, the Bays Maintenance Dredging Program – Long Term Environmental Management Plan.

Prior to finalising the Plan, Parks Victoria invited the public to make comments on the proposed changes. Once approved, the Long Term Environmental Management Plan will provide a framework for Parks Victoria’s updated maintenance dredging program while ensuring relevant statutory controls and obligations are met.

New sites

A number of infrequently dredged sites have been included in the Plan. These were not previously part of the dredging program, but are now considered, as most will need some level of maintenance within the next ten years. In most cases the sites will require further detailed investigation, design and funding prior to dredging.

The new sites include:

  • Queenscliff Moorings
  • Brighton Harbour
  • Hampton Harbour and Jetty
  • Patterson River Estuary
  • Hastings Jetty
  • Williamstown Precinct

New designs

To provide greater safety, efficiency, and environmental protection, some sites have had changes to their design or methodology.

These include:

  • Patterson River depth increased to -5.0m
  • Mordialloc, length of dredge area
  • Queenscliff, increase of dredge area to include mooring area for Ferry and dredge
  • Portarlington new entry channel and depth within the harbour
  • Werribee, depth increased to -2.5m
  • New methodology at Tankerton for in water disposal

Update June 2017

The feedback period for this project closed on 22 May 2017.  We are now collating and analysing submissions before finalising the plan.Thank you to everyone who made contributions during the consultation process.
