Summary
The dam, designed by NRCS and owned privately, stands at a height of 23.5 feet with a storage capacity of 83.39 acre-feet. It is classified as an earth dam with a stone core foundation, and its spillway width measures 40 feet.
This low-hazard potential structure is regulated and inspected by the North Dakota State Water Commission (NDSWC), with state permitting, inspection, and enforcement in place. While the dam is not associated with any federal agencies, its construction and operation are overseen by local authorities. The risk assessment for Lunder Dam indicates a moderate risk level (3), emphasizing the importance of proper maintenance and management practices to ensure the safety and functionality of the structure.
Overall, Lunder Dam plays a crucial role in mitigating flood risks in the area and protecting surrounding communities from potential water-related disasters. With its strategic location and design characteristics, this dam stands as a testament to the collaborative efforts between private owners and state regulatory agencies in safeguarding water resources and enhancing climate resilience in North Dakota.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation 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 in areas with population and significant infrastructure.
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.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
