What is a key characteristic of low-head dams?

A key characteristic of low-head dams is that they can trap boaters. Low-head dams often create a dangerous situation because the water flowing over them can form a strong recirculating current downstream. This current can capsize boats or prevent them from escaping the area, posing significant risks to anyone navigating nearby. Unlike traditional dams that might be more visible and feature designated safe areas, low-head dams tend to blend into the landscape; their danger often becomes apparent only when a boater unexpectedly approaches. This makes it critical for boaters to be aware of their location and understand the hazards associated with these structures.
