Summary
Built in 1988 for recreational purposes, this earth-type dam stands at a height of 6.5 feet and stretches for 390 feet, with a storage capacity of 360 acre-feet. It is regulated by the Michigan Department of Environment, Great Lakes, and Energy, ensuring proper inspection, enforcement, and permitting.
The dam serves as a vital component in managing the water resources of the tributary to Sturgeon River, providing flood control and recreational opportunities in the area. With a low hazard potential and a satisfactory condition assessment as of October 2017, Nahma Marsh Dam poses a moderate risk (rating of 3) according to the data available. While not owned or funded by federal agencies, the dam is crucial for maintaining the ecological balance of the surrounding wetlands and supporting wildlife habitats.
Overall, Nahma Marsh Dam stands as a testament to the intersection of water resource management and recreational enjoyment. Its role in regulating water levels and providing a safe environment for outdoor activities underscores the importance of sustainable infrastructure development in safeguarding both natural ecosystems and human communities in the face of changing climate conditions.

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.
