2010 Metro Mitigation Plan

Each dam is categorized by its hazard potential. Hazard potential is determined by the
downstream damage that could result if a dam failed.
High hazard – dams would probably cause loss of life in the event of failure.
Significant hazard – dams would cause property damage or temporary loss of roads
or utilities with a remote chance of loss of life.
Low hazard – dams would have little or no effect to life and property downstream in
the event of failure.
