The purpose of North Dakota’s dam safety program is to minimize the risk to life and property associated with the potential failure of dams in the state. Functions of the dam safety program include conducting dam inspections, maintaining an inventory of dams in North Dakota, determining the hazard classification of dams, and assisting with emergency preparedness activities.
A primary function of the dam safety program is to conduct dam inspections and provide recommendations to dam owners regarding necessary maintenance and repairs. Dam safety program staff inspects non-federally owned high hazard and medium hazard dams on a rotational basis. Additional inspections are conducted following the spring runoff, on request from dam owners, or when there are concerns at a dam, such as during flood events.
Dam maintenance and repairs are the responsibility of the dam owner. Funding to assist with dam safety repairs may be available through the State Water Commission’s cost-share program, or through other funding sources.
Emergency Action Plans
Emergency Action Plans (EAPs) are required for all high hazard and medium hazard dams under North Dakota Century Code 61-03-25. An EAP is a formal document that identifies potential emergency situations that could occur at a dam and specifies the course of action to be taken when an emergency situation arises. The purpose of an EAP is to minimize loss of life and property damage.
Dam owners are responsible for developing, testing, and updating an EAP for their dam. The State Water Commission has developed an EAP guidance document to provide additional guidance for developing, testing, and updating EAPs in order to comply with N.D.C.C. Section 61-03-25. A recommended EAP template, developed by the Natural Resources Conservation Service is also available. Additional general guidance on developing an EAP is available in the document “Federal Guidelines for Dam Safety - Emergency Action Planning for Dams” (link below). Funding to assist with developing an EAP may be available through the State Water Commission’s Cost-Share Program.
The dam safety program maintains an inventory of dams in North Dakota. North Dakota’s inventory of dams can be found on the Maps/GIS data page.
Dams in North Dakota are classified as low hazard, medium hazard, or high hazard based on the potential for loss of life or property damage downstream if the dam were to fail. These classifications are defined in North Dakota Administrative Code 89-08-01-01. The hazard classification is determined when an applicant applies for a construction permit for a dam. The hazard classification of a dam can also change over time due to changes in development downstream of the dam.
