Starting in late April and expected to be completed by mid-July 2025 (weather permitting), the project aims to improve the lagoon’s water quality and functionality, enhancing its appeal for both the local community and visitors alike.
Key Works to Improve the Lagoon
The rehabilitation project will involve several essential steps to restore the lagoon’s health and maintain its beauty for future generations. One of the first tasks is the gradual draining of the pond. The water will be carefully pumped out and used to irrigate the surrounding park vegetation and lawns, ensuring no water goes to waste.
Once emptied, the lagoon will undergo significant cleaning and maintenance. A key focus will be removing built-up silt from the bottom of the lagoon, which will help improve water quality and ensure better flow. Crews will also inspect and repair any cracks in the lagoon’s structure, helping to preserve its integrity.
In addition, invasive tree roots that may be damaging the lagoon’s infrastructure will be trimmed back, further protecting the space from long-term damage. The project also includes installing a new sand bed and pond liners, which will provide better filtration and reduce maintenance in the future.
To enhance the lagoon’s aesthetic and ecological value, the aeration and fountain systems will be repaired and reinstalled. These systems play an important role in oxygenating the water, supporting aquatic life and contributing to a visually appealing environment.
Once all the necessary works have been completed, the lagoon will be refilled with fresh water, bringing the area back to its full splendour. Throughout the entire project, a fauna spotter and catcher will be on-site to safely relocate any aquatic life that may be impacted by the works.
What Visitors Can Expect
During the rehabilitation period, visitors to the Botanic Gardens may notice some temporary disruptions, including increased noise, dust, and truck movements. While the garden gates will remain open, an exclusion zone will be established around the lagoon and on Alice Street to ensure safety during the works.
Traffic control will be in place to guide visitors through the area, and detour signage will help navigate any affected routes. Construction machinery will temporarily occupy part of the Bus Stop 95A bus zone on Alice Street, although timetabled bus services will not be disrupted.

By enhancing its water quality and ecological function, the project aims to offer a more enjoyable experience for all who visit this cherished natural space.
