What type of hazard is a lowhead dam classified as?

A lowhead dam is classified as a manmade hazard due to its construction and design by humans. These structures are often built for purposes such as flood control, irrigation, or water diversion. While they may exist in natural environments, the defining characteristic of a lowhead dam is that it is an artificial barrier in a river, creating dangerous hydraulic conditions downstream.

This classification is important in the context of swiftwater rescues, as it highlights the need for first responders to be aware of the specific risks associated with these hazards, such as strong currents and the potential for people to become trapped in the recirculating water created by the dam. Understanding that lowhead dams are manmade helps in assessing the appropriate safety protocols and rescue techniques that should be used when approaching situations involving these hazards.
