Introduction
The ongoing dredging project along the Hotham River, led by Apex Envirocare in partnership with the Shire of Boddington, is entering a significant new phase. With one Geotube already deployed to contain dredged sediment and operations progressing steadily upstream, the project is well on its way to removing an estimated 6,000 cubic meters of silt from the river.
A Key Milestone: Geotube Deployment
To manage the extracted material, Apex Envirocare has deployed a Geotube at the designated Laydown Area behind the Pool Centre. The Geotube, a large geotextile containment system, has so far accommodated around 300 cubic meters of dredged sediment. As dredging continues, additional tubes may be brought into service to safely store and dewater the large volume of silt that will be removed from the river.
Geotubes are a proven method in environmental and river rehabilitation projects. They allow water to drain out while securely containing fine sediment particles. Once filled and dewatered, the material can either be repurposed for land rehabilitation or safely disposed of, minimizing the environmental footprint of the dredging process.
Dredging Operations Around the Weir Completed
Early stages of the project focused on sediment buildup around the island near the weir. This critical section has now been successfully dredged, improving water flow and restoring depth. The dredging unit has since moved upstream, working towards the kayak access ramp. Project managers note that sediment volumes are expected to increase as the works advance further into the upper reaches of the river.
By removing accumulated silt, the dredging works are expected to restore natural flow patterns, reduce the risk of localized flooding, and enhance conditions for aquatic life. For recreational users, the cleared sections will also improve accessibility for activities such as kayaking and fishing once works are complete.
Community Safety Remains a Priority
The Shire of Boddington has emphasized the importance of community safety during the ongoing works. Exclusion zones have been established around active dredging sites, clearly marked with signage and flagging.
“While dredging works progress, the community is reminded to respect the exclusion zones marked with signage and flagging. These measures are in place for public safety, as this area is currently an active worksite,” the Shire said in a recent update.
Residents and visitors are encouraged to observe all instructions to ensure the safety of both the public and workers. Heavy equipment, pipelines, and the active dredge present hazards that require controlled access.
Why Dredging is Essential for the Hotham River
Over time, rivers naturally accumulate sediment due to erosion, vegetation decay, and runoff from surrounding land. In the case of the Hotham River, significant siltation had reduced water depth, restricted flow, and created environmental challenges. If left unaddressed, these issues could affect both ecosystem health and community use of the river.
Dredging provides a long-term solution by physically removing the buildup of sediment. The 6,000 cubic meters of silt targeted in this project represents years of accumulation. Clearing it will help restore the river to a healthier, more stable condition while also supporting the Shire’s broader environmental management goals.
Environmental Management and Future Benefits
The use of Geotubes underscores the environmentally conscious approach being taken. By preventing sediment from re-entering the river and ensuring controlled dewatering, the method helps protect water quality throughout the project.
When the project is complete, the benefits are expected to be wide-ranging:
- Improved water flow – reducing stagnation and enhancing river health.
- Better aquatic habitat – supporting native fish and other wildlife.
- Recreational improvements – restoring safe access for kayakers and other river users.
- Community resilience – lowering flood risks and maintaining the river as a valuable natural asset.
The project also reflects a broader trend of regional councils investing in river restoration to balance ecological health with community use.
Looking Ahead
With dredging moving further upstream, the coming weeks will see higher sediment volumes extracted and stored in Geotubes at the Laydown Area. Once all 6,000 cubic meters of silt have been removed, final dewatering and sediment management will take place before the riverbank areas are restored.
The Shire of Boddington has committed to providing ongoing updates to keep the community informed. Residents are encouraged to stay engaged with the project’s progress while adhering to safety guidelines.96*
As Apex Envirocare continues to deliver on this complex task, the Hotham River is steadily being revitalized. When complete, the project will leave behind a healthier waterway, benefiting the environment, local residents, and visitors for years to come.
