Summary
Built in 1900, this concrete dam stands at a height of 26 feet and has a length of 150 feet, providing a storage capacity of 121 acre-feet. The dam, situated on Heald Stream, offers a surface area of 20 acres for recreational activities such as boating, fishing, and wildlife observation.
Managed by the Maine Emergency Management Agency (MEMA), Heald Stream dam is regulated, permitted, inspected, and enforced by the state. With a low hazard potential and a condition assessment of "Not Rated," the dam is currently in a stable condition. While the dam has not been modified in recent years, regular inspections are conducted to ensure its safety and compliance with regulatory standards. The presence of a spillway with a width of 72 feet further enhances the dam's ability to manage water levels and prevent potential flooding events.
For water resource and climate enthusiasts looking to explore Heald Stream, this recreational dam offers a picturesque setting for outdoor adventures while also serving as a vital structure for water management in the area. With its historical significance dating back over a century, Heald Stream dam continues to be a valuable asset for both local residents and visitors seeking a tranquil escape in the heart of Maine's natural beauty.

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.
