Seqwater Hosts Community Sessions for Lake Macdonald Dam Upgrade
Seqwater is running community information sessions for the Lake Macdonald Dam Improvement Project as preparation ramps up for major construction works starting this year. The sessions began in late January and will continue until 15 February.
The project, part of Seqwater’s broader Dam Improvement Program, aims to enhance water security and strengthen the dam’s ability to withstand extreme weather events. Preliminary works began in November 2024, including the construction of haul roads and office buildings, as well as aquatic fauna surveys. Gradual lake lowering has also been underway since late last year to prepare for the wet season and upcoming construction activities.
Seqwater’s Executive General Manager of Infrastructure, Planning and Capital Delivery, Sarah Dixon, emphasised the significance of the project for the region.
“Seqwater is embarking on its largest-ever capital investment program, paving the way for a decade of enhanced water security and reliability for South East Queensland – and the Lake Macdonald Dam Improvement Project is a vital part of this initiative,” Sarah said.
Project Phases and Construction Plans
Phase 1 works will involve the construction of a temporary upstream cofferdam, which will be removed once the new wall is completed. This will enable the safe development of a new spillway and the reconstruction of the dam’s earth embankments. These upgrades will ensure the structure meets modern regulatory standards while maintaining the lake’s water level as much as possible to support environmental, recreational, and community needs.
“Sunshine Coast locals are encouraged to attend one of our information sessions, where members of the project team will be available to answer any questions,” she added.
John Holland has been selected as the major construction contractor for the Lake Macdonald Dam Improvement Project, which is expected to take approximately five years, depending on weather and site conditions. The project is anticipated to create around 150 jobs over its duration.

📍 Cooroy Library – Wednesday, 5 February | 2:30 to 5:00 pm
📍 Pomona Memorial Hall – Saturday, 15 February | 9:00 to 11:30 am
