Ensuring public safety around dams is a critical responsibility for communities and conservation authorities. In the heart of Norwich, Ontario, the scenic Otter Creek winds its way through the community. It culminates at the Norwich Dam — a structure central to local recreation and water management. But as with many dams across Canada, this vital infrastructure posed a serious safety risk to the public. This was especially true for recreational users upstream. The local authority recognized this risk and initiated a solutions-driven approach to mitigating hazards and protecting the public.
Dams and reservoirs, while vital for recreation and water management, pose inherent dangers to the public, especially to unsuspecting canoeists, kayakers, swimmers and boaters who may drift too close.
At Norwich Dam, the need for improved safety was clear. The area upstream of the dam – known as the headpond – can appear deceptively calm. It attracts visitors for recreation, but strong currents, changing water levels and sudden drops create hazardous conditions, particularly near the dam face.
Adding to the complexity, this was not just a summer concern. The boom system would need to withstand all four seasons, surviving not only water flow but also the harsh winter freeze-thaw cycles, ice buildup and debris impact.
1. Accidental entry of boaters or swimmers into hazardous zones.
2. Insufficient physical barriers to prevent access to dangerous waters.
3. Environmental challenges such as ice loads and debris impacting safety infrastructure.
4. The need for compliance with evolving safety standards and regulatory guidelines.
To address these issues, the authority initiated a plan to implement a permanent public safety boom system upstream of Norwich Dam. That’s where our partner, ADOR – for Ecocoast projects in Canada – came in.
The installed solution was a fully customized Bolina Watercraft Safety Boom CAB400, selected for its proven durability and performance in challenging environmental conditions. Our team engineered the boom system to redirect waterway users away from the dam’s danger zone. We carefully selected its alignment to ensure low-flow interaction, aiding in swimmer self-rescue and minimizing hydraulic risk.
We designed the system to remain in place year-round. It is built specifically to withstand ice loads, high flow conditions and heavy debris during spring thaw or storm events.
The solution adhered to all requirements outlined by the Guidelines for Public Safety Around Dams and Ontario’s Lakes and Rivers Improvement Act, ensuring both safety and ecological responsibility.
The public safety boom transformed Norwich Dam from a potential danger point into a clearly defined and proactively managed safety zone.
By prioritizing a problem-solving approach, the Norwich Dam project delivered a boom system that:
1. Effectively prevents unauthorized access to dangerous waters.
2. Withstands harsh seasonal and environmental conditions.
3. Aligns with best practices for public safety around dams.
4. Minimizes long-term maintenance needs and operational disruptions.
This project stands as a model for other communities facing similar challenges, demonstrating that a holistic, solutions-oriented strategy can significantly enhance public safety while meeting environmental and regulatory requirements.
Communities across Canada continue to embrace outdoor water recreation. With this increased use comes a greater responsibility to protect lives. Projects like the Norwich Dam boom installation demonstrate how engineering solutions, informed by local knowledge, can mitigate risk effectively. These solutions are customized to site-specific challenges and remain affordable.
If your community is considering public safety improvements around water infrastructure, take inspiration from Norwich Dam. Start with the problem, involve stakeholders and pursue a custom, compliant solution that stands the test of time.

Ecocoast’s Watercraft Safety Booms are designed to protect the public by preventing access to hazardous zones near dams. These systems are especially effective in keeping recreational users, such as boaters, swimmers and paddlers, away from dangerous areas upstream. For example, in the Norwich Dam project, the fully customized Bolina Watercraft Safety Boom CAB400 was chosen for its proven durability and high performance in challenging environments, including fast currents, ice formation and floating debris.
The CAB400 is purpose-built for challenging aquatic environments such as headponds, rivers, and reservoirs upstream of dam structures. These areas may seem calm but often involve hidden dangers like strong subsurface currents, fluctuating water levels, sudden hydraulic drops, seasonal ice loads and floating debris impacts. The CAB400 is designed to perform reliably in all these conditions, making it ideal for public safety around dams.
The CAB400 improves waterway safety by creating a clearly marked physical barrier that guides boaters, swimmers and paddlers away from dangerous zones near dams. Its strategic placement leverages low-flow areas to enhance self-rescue opportunities and minimize exposure to hazardous hydraulics. Built with durable materials, the CAB400 withstands year-round challenges such as ice, strong currents and heavy debris, ensuring reliable protection and reducing the risk of accidents in complex water environments.
Yes. Every Bolina Watercraft Safety Boom is fully customizable to meet the unique needs of each dam project. Customization options include adjustments to boom length, float spacing and alignment to fit site-specific conditions. Additionally, clients can specify colors, branding and signage to ensure the safety barriers integrate with regulatory requirements.
Ecocoast starts with a comprehensive risk assessment to identify critical hazards, such as accidental entry points, hydraulic risks, ice loads and debris impact zones. This detailed evaluation guides the subsequent site survey, helping our marine engineers design an optimal boom alignment and select appropriate specifications. The process ensures the final safety boom layout effectively protects the public while complying with environmental regulations and site-specific conditions.
In addition to custom boom length and alignment, Ecocoast offers a wide range of add-on options for the CAB400, including:
● Safety enhancements: Casualty lifelines, grab handles and warning signage for clear hazard communication and rescue support.
● Marine services: Complete support from assembly and installation to maintenance and recycling at end-of-life.
● Advanced marine engineering: Boomforce software to enable precise simulation of a structure’s response to factors like waves, wind, watercraft impact and similar environmental situations.
● Vessel monitoring: Integration of monitoring systems for real-time safety oversight and incident response.
Safety Booms are anchored using reliable, site-specific mooring solutions to ensure maximum security and effectiveness in all water conditions. Standard mooring methods include shore anchoring, where the boom ends are fixed to strong land-based structures using galvanized shackles and wire ropes. Another method is in-water anchoring using buoyed lines attached to robust seabed anchors like Danforth or pyramid anchors. For long or high-flow installations, intermediate anchor points and chains provide extra stability.
These mooring solutions are designed for durability, corrosion resistance and adaptation to factors like current, wind, and water level changes. Our anchoring systems are trusted for dams, rivers, reservoirs and industrial sites, delivering safety and reliable performance wherever they’re installed.
