National Inventory of Dams Inclusion Criteria

For defintions of hazard, please use data dictionary:

Downstream Hazard Potential

Code indicating the potential hazard to the downstream area resulting from failure or misoperation of the dam or facilities:

L for Low;
S for Significant;
H for High.

Definitions, as accepted by the Interagency Committee on Dam Safety, are as follows:

1. LOW HAZARD POTENTIAL -- Dams assigned the low hazard potential classification are those where failure or misoperation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner’s property.

2. SIGNIFICANT HAZARD POTENTIAL -- Dams assigned the significant hazard potential classification are those dams where failure or misoperation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be located in areas with population and significant infrastructure.

3. HIGH HAZARD POTENTIAL -- Dams assigned the high hazard potential classification are those where failure or misoperation will probably cause loss of human life.

High hazard dams shown are designated by the US Army Corps of Engineers on the National Inventory of Dams database.
