Hazard class and condition, each as the NID defines it

Hazard class

Hazard Potential Classification
Low

“Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner’s property.”

The NID defines the field: “Category to indicate the potential hazard to the downstream area resulting from failure or mis-operation of the dam or facilities. It reflects probable loss of human life and impacts on economic, environmental, and lifeline interests. The hazard potential does not speak to the condition of the dam or the risk of the dam failing.”

Condition

Condition Assessment
Not Rated
Condition Assessment Date
Not given

“The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.”

The NID defines the field: “Assessment that best describes the condition of the dam based on available information.”

The record, as the NID prints it

Each field is under the NID’s own label, with the unit the label names. A date later than the file’s own is printed as the NID prints it. The record’s own date is October 6, 2026; the file’s is October 30, 2026.
