RESERVE, LOUISIANA – Malibou Lake, a historic and environmentally significant landmark in Southern California, has faced severe sedimentation challenges in recent years following the 2018 Woolsey Fire. The fire impacted approximately 68 miles of upstream terrain, leaving exposed soil that was carried into the lake during subsequent rainfall events. Over time, this influx of sediment reduced lake depth, contributed to flooding concerns, and impacted both the surrounding community and the lake’s ecological balance.
Established in 1922 at the confluence of Triunfo and Medea Creeks, Malibou Lake sits within the Santa Monica Mountain range. Today, more than half of its shoreline remains in a natural state, supporting a wide range of wildlife and serving as an important ecological corridor within the region.
For the surrounding community, Malibou Lake is more than a body of water, it remains a shared space for recreation, wildlife, and everyday life.
A Community-Driven, Targeted Dredging Approach
To address these challenges, the Malibou Lake community formed a dedicated committee, the Super Dredge Committee, to evaluate dredging manufacturers and identify the most effective solution for the project. Following this process, DSC Dredge and its Moray Class dredge were selected to support the lake’s restoration.
Designed for portability and efficiency, the Moray Class is well-suited for shallow and environmentally sensitive waterways, allowing for effective sediment removal while working within the lake’s natural setting.
Engineered for Performance in Complex Environments
The Moray Class dredge offers key capabilities aligned with the project’s needs, including:
– Portable design for efficient transport and rapid deployment
– Swinging ladder with submerged pump for effective sediment removal
– Walking spud carriage for continuous operation
– Advanced controls and positioning systems for precision dredging
These features support efficient sediment removal while operating within the physical and environmental constraints of the lake.
Enhanced Visibility and Support Through Integrated Technology
In addition to the dredge’s engineering design, the Malibou Lake committee agreed to include DSC Vision, a technology system that provides real-time visibility into dredging operations, including depth, positioning, and dredging progress through live mapping of the lake bottom.
“I’ve operated dredges for 20 years, but when we started using DSC Vision, it was like being able to see,” said Stephen Hoofring, Volunteer, Malibou Lake Mountain Club. “Prior to DSC Vision, we left things behind because we didn’t know. Now we can see it and clean it as we go.”
The system provided clear visibility into lake conditions, including depth and overall topography, helping guide where and how dredging was performed.
“It lets us know how deep you are, where you’re going, and the areas that need to be dredged. Before, we were basically working blind. This makes it much easier,” said Tony Herrera, Dredge Operator.
He added that DSC Vision was easy to use. DSC’s team provided on-site training, allowing the crew to quickly become comfortable with the system.
The team also noted the value of DSC’s Dredge Rx system, which allows DSC’s support team to log in remotely, identify issues, and guide the crew through solutions in real time.
Progress and Accelerated Timeline
With restoration progressing, and more than fifty percent of the lake already restored to its natural depth, Hoofring noted, “We’ve made significant progress, and based on our current projections, we expect to restore the lake to its pre-fire depth this year, two years ahead of schedule.”
A Collaborative Effort with Lasting Impact
“The Malibou Lake project is a great example of what can be achieved when the right equipment is paired with a clear objective and strong community commitment,” said Bob Wetta, DSC Dredge. “We’re proud to support a project that not only restores functionality but also brings long-term value back to the community.”
A Continued Commitment to Practical Solutions
DSC brings decades of experience in designing and manufacturing customized dredging solutions for complex environments.
The Malibou Lake project reflects a broader commitment to supporting communities through practical, engineered solutions that restore functionality while respecting the surrounding environment.
