Summary
With a primary purpose of serving as a fire protection, stock, or small fish pond, this concrete dam on Marsh Stream also has the capacity for hydroelectric power generation. Spanning 260 feet in length and standing at a height of 18 feet, the dam offers a storage capacity of 90 acre-feet.
Maintained and regulated by the Maine Emergency Management Agency (MEMA), the Frankfort dam is equipped with state-permitted and inspected features to ensure its safe operation. With a low hazard potential and a condition assessment that is currently not rated, the dam continues to provide valuable water resource management for the surrounding area. Despite lacking certain modern amenities such as an emergency action plan and inundation maps, the dam remains a crucial asset for fire protection and agricultural purposes.
The surrounding community benefits from the Frankfort dam's presence, as it provides essential water storage and flood control measures. With its historical significance and ongoing role in water resource management, the dam serves as a reminder of the importance of sustainable infrastructure for both local residents and the environment. As climate change continues to impact water resources, the Frankfort dam stands as a valuable asset for the region's resilience and preparedness in the face of evolving challenges.

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.
