Patterson Lakes Waterways

Patterson Lakes is a suburb in the south of Kingston formed around a series of waterbodies known as the Tidal Waterways and Quiet Lakes.

Collectively the waterbodies are referred to as the Patterson Lakes Waterways and they play an important role in the regional drainage system and provide flood protection. The Tidal Waterways consist of a series of canals and harbours that are connected to the Patterson River and in turn to Port Phillip Bay.

The Quiet Lakes comprise three landlocked lakes being Lake Legana, Lake Illawong and Lake Carramar which are connected to each other and to the Patterson River and Kananook Creek via pumps and drains.

In total the waterways provide around 23 kilometres of shoreline water frontage to more than 1,200 residential properties. The Waterways is highly valued by the local community and Council allocates Melbourne Water funding to provide beach maintenance services through a service agreement.

All Patterson Lakes beach maintenance works are delivered by Melbourne Water for Kingston City Council. The service detail and scheduled dates can be viewed in the Annual Beach Maintenance Program for 2020/21. Please note the scheduled dates provided are an estimate only, dates may vary due to unforeseen circumstances related to weather, tidal movements, contractor availability and equipment breakdown.    

Beach maintenance schedule update


Residents of the Tidal Waterways please be advised of the following service method changes to assist with weed maintenance of the beach areas. Services will be delivered by Melbourne Water Contractors as per Councils instruction.

  • Beach areas with significant weed growth will be mowed, with the clippings collected.  A mechanical rake using a harley rake attachment will be done to assist with further removal of weeds from the surface and followed up with a weed steaming application. 
  • Beach areas where mechanical raking with the harley rake cannot be used. These areas will be mowed where appropriate followed up with a weed steaming application.

Services are proposed to commence on Monday 19th October 2020. However should the contractor have the equipment available for use this will begin by the end of the week.


We appreciate your patience and understanding during this time and will try to minimise impacts and disruptions to residents where possible.



Weed Maintenance Services

In support of Council’s Resolution to cease the use of glyphosate herbicides Council is working with other industry partners to consider possible alternative approaches to weed control and recognise that the immediate response may not be the most effective or appropriate in the long term.  However, we will continue to work through the change in order to ensure the best outcome for the community.

Under the direction of Council, Melbourne Water contractors are undertaking weed steaming as an alternative treatment. Please be advised weed steaming is time consuming and beach access via the barge to most areas to undertake the service is subject to tidal movements. Weed steaming services can only be undertaken between mid and high tides.

Currently Council is introducing an alternative treatment for the 2020/21 Beach Maintenance Program for the Tidal Waterways, which includes substituting beach planing for mechanical raking to assist with the disturbance of weed growth so debris can be collected and removed.

Water Quality

At times, particularly in warm weather, aquatic growth can occur and be seen in the waterways. This usually occurs from October to January. These water plants are common and generally pose no risk to human, animal or environmental health, in fact they provide some environmental benefits toward improving water quality.  

Removing and disposing of these water plants is not included in the beach maintenance program. Residents who choose to rake up the algae/aquatic plants should dispose of it themselves or it should be left to breakdown and disappear naturally.

Any enquiries regarding water quality should be directed to Melbourne Water by phoning 131 722 or emailing
