With plans for Lake Wyangan's foreshore redevelopment given the green light last week, Griffith City Council can also reveal the 18-week treatment trial to improve water quality is on track to be completed by early January 2025.
A sustainable treatment using Enviro – Diatomix is currently being carried out in the South Lake. If successful, it is hoped Council will see a reduction in Blue Green Algae (BGA) and the overall health of the Lake's ecosystem enhanced.
As part of this process, additional silica has been added to the Lake to support the growth of beneficial diatoms (microscopic organisms). Observations during the process reveal that Diatomix is feeding on the Lake's existing silica more rapidly than anticipated, further demonstrating its active role in improving water quality.
Results of the treatment's effectiveness should be known within 6–12 months, during which further analysis will provide conclusive evidence. If successful, Council plans to expand the initiative to include North Lake Wyangan.
While the water treatment progresses, Council is also advancing plans for Lake Wyangan's foreshore development, supported by $1,030,000 from the Local Roads and Community Infrastructure Program (LRCIP) Phase 4. A highlight of Stage 1 is the delivery of a new, inclusive playground, which will be completed by April 2025.
The playground will feature:
- Adventure Multiplay Playground: Includes a climbing net, ground-level activities, and slides
- Three-Bay Swings: Featuring toddler seats and a pod swing
- Climbing Tower
- Sand Factory and Sand Digger
- Hip Hop: A see-saw-inspired play element
- Double Flying Fox.
Wheelchair-accessible features include:
- Tugboat Springer
- Cubby House
- Inclusive Roundabout
Shaded play areas, identified as a priority during community consultations, have been incorporated into the final design.
Griffith Mayor Doug Curran said he felt optimistic about the combined efforts to enhance both the Lake's water environment and recreational amenities.
"The Diatomix treatment is a promising bio solution to tackle blue-green algae, and we are optimistic about its results. At the same time, the new foreshore developments, especially the inclusive playground, will create a vibrant community space for residents and visitors to enjoy. These projects represent our commitment to both environmental sustainability and community well-being," he said.
Council will continue to monitor the treatment and update the community on the progress of both initiatives.
