Brisbane City Council has released a strategic management plan for Forest Lake, with over $1 million to be invested to address the issues affecting the lake.

Developed with the help of a group of experts including scientists and external water experts, the Forest Lake management plan looks to provide long-term solutions to improve the health of the lake for the sake of the community and the environment.

The management plan will be implemented in a span of two and a half years and should result in reduced algal blooms on Forest Lake and better health of the lake ecosystem.

Solutions and Outcomes of the Management Plan

Among the issues that will be addressed in the strategic management plan are the proliferation of blue-green algae, the growth of the highly invasive water weed salvina, and ibis population increase leading to stench issues and high nutrient levels in the lake.

Due to the complexity of the issues in the man-made lake, the council has formed a dedicated expert working group to make sure that the solutions are all based on expert advice.

The council’s experts also had the support of the likes of Professor David Hamilton, who serves as Deputy Director of the Australian Rivers Institute at Griffith University. Tony, Webster, a leading expert in the field of catchment modeling and water quality, also assisted in the creation of the Forest Lake management plan.

Investigation works started in March 2019, with the final strategic management and rehabilitation plan completed in July. With planning and design also completed, the council now moves to the next step of completing approvals, permits, procurement and tendering.

The actual desilting is expected to start sometime in April 2020, followed by replanting in the desilted zones.
