Summary
The dam, primarily designed for Fish and Wildlife Pond purposes, stands at a height of 37 feet and spans a length of 700 feet. It has a normal storage capacity of 659 acre-feet and a maximum storage capacity of 967 acre-feet, making it a significant water resource for the surrounding area.
The dam, constructed with an Earth core and Stone foundation, is regulated by the North Dakota State Water Commission and undergoes regular inspections and enforcement measures. With a spillway width of 80 feet and a Hazard Potential rated as Significant, the dam presents a moderate risk level. The dam has undergone modifications in 1996 and 2001, focusing on the foundation and hydraulic aspects, respectively. Despite not being condition rated, the dam serves as a critical structure for water management and wildlife conservation in the region.
Overall, North Lemmon Lake Dam plays a vital role in maintaining water resources and supporting wildlife in the area. With its historical significance dating back over a century and ongoing regulatory oversight, the dam serves as a key asset for the community. As climate change impacts water availability and quality, the proper management and maintenance of dams like North Lemmon Lake Dam are essential for sustainable water resource management and climate resilience.

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.
