Frequently Asked Questions
Hazard potential is based on the consequences of dam failure, not the condition of the dam. High hazard means loss of human life is probable. Significant means economic and environmental losses are expected but no probable loss of life. Low means minimal losses are expected. The classification considers downstream population, infrastructure, and environmental resources.
Condition ratings reflect the physical state of the dam based on periodic inspections. Satisfactory means no deficiencies found. Fair means minor issues exist but no immediate action needed. Poor means safety deficiencies require remedial action. Unsatisfactory means the dam is unsafe and immediate corrective action is required.
