The ACT Government has released a Healthy Waterways Plan for Lake Tuggeranong, setting out a 10-year vision to reduce pollutants entering the lake.
Minister for Climate Change, Environment, Energy and Water, Suzanne Orr said the Plan incorporates feedback received from the community consultation undertaken late last year and provides a clear roadmap to improve the long-term health and resilience of Lake Tuggeranong.
“Lake Tuggeranong is really important to the community, supporting recreation, connection with nature and wellbeing,” Minister Orr said.
“Unfortunately, nutrient pollution entering the lake through urban stormwater runoff continues to contribute to harmful algal blooms that impact how people are able to use and enjoy the lake.
“Scientific assessments confirm that excess phosphorus entering the lake through stormwater is the main driver of algal blooms. The phosphorus comes from things like leaves, grass clippings, fertilisers and sediment from roads and driveways.”
The ACT Government has committed $2.7 million in the 2026-27 Budget to get key actions underway now, including additional street sweeping, supporting residents to improve gardening practices, strengthening research and monitoring, and trialling anti‑algal technologies.
“While algal blooms can’t be eliminated entirely, the actions set out in this plan will work to reduce the number of lake closures and make blooms shorter and easier to manage,” Minister Orr said.
“Our actions will evolve as we learn what works best in real conditions. We’ll test, refine and scale up the most effective solutions, backed by ongoing research and monitoring.
“Everyone can play a role in improving the health of Lake Tuggeranong. Residents, businesses and community groups can help keep Lake Tuggeranong clean and healthy by adopting waterway-sensitive gardening practices and putting fallen leaves and grass clippings in the green bins.”
