Summary
The earth dam, completed in 1966, stands at 20 feet high with a hydraulic height of 18 feet and a length of 150 feet. With a storage capacity of 8 acre-feet and a surface area of 1 acre, the pond serves as a vital resource for the local community.
Managed by the Maine Emergency Management Agency, Heart Pond is state-regulated and undergoes regular inspections to ensure its structural integrity and safety. Despite being classified as having a significant hazard potential, the dam is currently assessed to be in fair condition. With a spillway width of 102 feet, the pond is equipped to handle potential overflow events, providing further peace of mind to residents and officials alike.
Surrounded by the natural beauty of Lincoln County, Heart Pond offers not only practical benefits but also serves as a tranquil retreat for wildlife and visitors. As a crucial water resource in the region, the pond's management and maintenance reflect a commitment to both environmental stewardship and community safety.

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.
