Maylands Lakes

The City is aware of an algal slick affecting Lakes Bungana and Brearley, primarily at the southern and western portions of the site. The City is monitoring the situation and will undertake water quality testing to better understand the cause and determine any further action. We will continue to monitor the area and provide updates.

As part of implementation of the Maylands Lakes Restoration Masterplan, a combined dosing of an algaecide (Earthtec, a copper sulfate solution) and Phoslock (a manufactured clay product that binds phosphorus) was undertaken in March 2026.

Preliminary monitoring results have been received as part of a higher frequency water sampling protocol introduced to assess the impacts of the dosing on lake water quality and algal cell counts.

The results of this monitoring are set out in this report from Alluvium Consulting.

Contractors will be undertaking required track pruning at the western track at Lake Bungana and Lake Brearley on Monday 22 June between 7am and 5pm.

During these works, two sections of the path will be closed at various times across the day.

The purpose of the pruning is to provide adequate path clearance for pedestrians and cyclists, and to provide a safe line of sight to oncoming traffic.

Track management, including signage, onsite personnel and detours will be in place.

On Thursday 4 June, the City held its sixth Maylands Lakes Community Forum at the Maylands Sport and Recreation Club.

Contractors will be returning to Brickworks Lake next Wednesday 20 May to undertake groundwater sampling to gather essential data for the geotechnical report.

Contractors were onsite on Tuesday 12 and Wednesday 13 May undertaking field work for the development of the geotechnical report for Brickworks Lake and its immediate surrounds.

This is an essential study in the lead-up to tendering the Brickworks Biofilter project – a key action of the Maylands Lakes Environmental Restoration Masterplan.

A request for tender for this project is expected to be called in June.

The next Maylands Lakes Community Forum will be held on Thursday 4 June 2026.

The forum will provide an update on Phase 1 implementation of the Maylands Lakes Environmental Restoration Masterplan.

Time: 5.30pm (for a 6pm start) until 7.30pm

Date: Thursday 4 June 2026

Location: Maylands Sport and Recreation Club, 50 Clarkson Road

RSVP: By 5pm, Friday 29 May 2026 to Executive Assistant Infrastructure and Assets, Siiri Clausnitzer, via siiri.clausnitzer@bayswater.wa.gov.au or 9272 0622

Letters inviting the community will be hand-delivered from Monday 18 May.

We thank you for your patience and understanding as we work to improve the environmental conditions at Maylands Lakes.

Algaecide dosing will now commence Tuesday 3 March and may extend to Wednesday 4 March, due to a requirement to also treat Lake Bungana.

While the algal bloom at Lake Bungana is less severe than the bloom at Lake Brearley, treatment is required to provide the most suitable conditions for the upcoming Phoslock dosing.

The City has engaged consultants to service the mixers in Lakes Bungana and Brearley next week.

Works are expected to take place from Tuesday to Wednesday 3-4 February 2026.

A crane will be on site to retrieve and return the mixers following offsite servicing.

The City has been monitoring the nests visible on the mixers and has confirmed there is no cormorant activity.

Planning and design are now underway for key restoration works, including improving water circulation at Lake Brearley and the detailed design of a treatment wetland at Brickworks Lake.

While these works seek to address environmental issues, the Landscape and Green Infrastructure Assessment takes a broader view, looking at how the lakes, vegetation, pathways and open spaces could be enhanced to benefit both the environment and community.

The primary purpose of this assessment is to provide a clear understanding of current conditions and to communicate why ecological and landscape changes are necessary to address ongoing issues such as algal blooms and midge.

This framework is intended to inform the design of a future landscape restoration masterplan, ensuring interventions are evidence-based, balanced and sensitive to ecological and community values.

Throughout December the City's consultant engaged with the Community on the Landscape and Green Infrastructure Assessment. Based and the assessment, together with the community feedback received they are now drafting Landscape Restoration Masterplan.
