Summary
The dam, constructed in 1900, is primarily made of concrete and stands at a height of 13 feet with a length of 175 feet. It has a storage capacity of 81 acre-feet with a normal storage level of 72 acre-feet, covering a surface area of 10 acres.
The dam, situated on Frost Brook, is regulated and inspected by the Maine Emergency Management Agency (MEMA) to ensure compliance with state regulations and safety standards. Despite its low hazard potential, the dam's condition was assessed as fair during its last inspection in August 2002. Although the dam has not undergone any major modifications in recent years, regular inspections are conducted every 12 months to monitor its structural integrity and address any potential risks.
Overall, Cider Mill Dam plays a crucial role in providing essential water resources for the surrounding community while also supporting important ecological and recreational functions. Its presence underscores the importance of proper dam management and maintenance to ensure the safety and sustainability of water resources in the region, particularly in the face of changing climate conditions.

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.
