Summary
The dam serves primarily for recreational purposes, with a focus on providing opportunities for water-based activities in the area. It stands at a height of 27 feet and has a structural height of 43 feet, with a length of 600 feet and a maximum storage capacity of 649 acre-feet.
The dam is situated on the Maple River-TR and is regulated by the NDSWC, with the state of North Dakota overseeing its permitting, inspection, and enforcement processes. Despite its low hazard potential, the dam underwent structural modifications in 1975 to enhance its safety and functionality. With a moderate risk assessment rating, the Kulm Edgeley Dam remains a key feature in the region's water resource management, offering both recreational opportunities and essential flood control measures.
Overall, the Kulm Edgeley Dam provides a vital water resource for the community, offering a surface area of 27 acres and a normal storage capacity of 330 acre-feet. With its uncontrolled spillway and slide outlet gates, the dam ensures proper water management and flood protection for the surrounding area. As a significant contributor to the region's climate resilience, the dam plays a crucial role in balancing water supply needs with recreational demands, making it a valuable asset for water enthusiasts and climate advocates alike.

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.
