Dams serve essential purposes, from water storage and flood control to hydroelectric power generation. However, they also present serious safety risks for those who live near them or engage in water activities nearby.
Understanding the potential dangers around dams can help individuals stay safe and allow dam operators to take steps to reduce risks. Below are four dam-related hazards that require caution.
1. Dangerous hydraulic currents
One of the most lethal hazards near dams is the formation of a hydraulic roller, also known as a “drowning machine.” This occurs when water flows over a low-head dam, creating a powerful recirculating current that can trap swimmers, boats or debris. The force of these currents makes escape nearly impossible, even for strong swimmers. Water aeration in these rollers also reduces buoyancy, making life jackets less effective in keeping someone afloat.
2. Hidden debris and strainers
The water near dams can carry debris such as fallen trees, rocks and other objects that get trapped against the dam structure. These obstacles, known as strainers, allow water to pass through but can pin a person or boat against them, making escape difficult. Seepage from dams can also create suction currents that pull people and debris toward the dam face, increasing the risk of entrapment.
3. Poorly marked or hidden dams
Some dams, especially low-head dams, can be difficult to see from upstream. They may blend into the surrounding water, creating a “false horizon” effect that makes it hard for boaters and kayakers to recognize the drop-off before it’s too late. Without clear warning signs, individuals may unknowingly drift too close, increasing their chances of being swept over the edge.
People sometimes underestimate or are unaware of the risks of engaging in recreational activities near dams. Taking precautions, staying informed and following posted warnings can help people stay safe. If injured in a dam accident, seeking legal guidance can help determine liability and explore available options for recovery.
