Bungana, Brearley and Brickworks

As you may be aware, the water quality at Lake Bungana and Lake Brearley is currently poor with both lakes experiencing algal blooms.

Over the last year the City has worked implementing a number of short term actions to address these water quality challenges, including works to enable the fountains to the turned on, and a system to help oxygenate the Brickworks Lake.

Removal of Algae - Lake Brearley

In response to concerns raised by the community regarding the odour and decreased amenity of Lake Brearley, associated with algal blooms, please be advised that Council, at its Community, Technical, Finance and Corporate Services Committee Meeting of 21 August 2018, considered the matter and resolved as follows:

That Council:

  1. Supports the increased service level of manually removing vegetation and algae in the identified problem areas of Lake Brearley once a month and the funding be sourced from the existing Maylands Lakes Capital Works budget.
  2. Advises affected residents and the Friends of Maylands Lakes of the increased service level to the Maylands Lakes."

The material will be manually cleaned or scooped out of the lake once a month in order to manage the odour and accumulation of vegetation and algae in the lake in the short term whilst the longer term management options are undertaken.

Poor water quality drivers and solutions.

Commencing in 2015, the City undertook a 12 month water quality study and commissioned an environmental consultant to review the data for the Maylands Lakes. The environmental report findings recommended short and long term options. This report can be found at:

On the 24 October 2016, an information session was held to share the findings of this report. The presentation and FAQ from this presentation can be found as follows:

Phoslock application

The application of phoslock to the three lakes will commence on Monday, 19 February 2018, and will be implemented over approximately one week.

The Phoslock will be applied to the lakes by boat and from the edge of the lake by hose. The clay has a white colour and this intern will give the lakes a milky colour for approximately 1-2 weeks as the clay settles through to the bottom of the lakes. This process binds phosphorous from the water column and will help to minimise re-release of phosphorous from the sediment back into the water column.
