Summary
The dam, primarily made of earth with a buttress core type, stands at a height of 28.7 feet and has a hydraulic height of 26.6 feet. With a storage capacity of 1560 acre-feet, the dam regulates water from Dark Brook and Wellington Brook, creating a surface area of 116 acres for various water activities.
Despite its satisfactory condition assessment, Eddy Pond Dam is classified as having a high hazard potential, prompting a biennial inspection frequency to ensure its safety and structural integrity. The Department of Conservation and Recreation in Massachusetts oversees the state regulation, permitting, and inspection of the dam, emphasizing the importance of maintaining a robust emergency action plan and risk assessment to mitigate any potential threats. The dam's proximity to a populated area underscores the necessity of effective risk management measures to safeguard both the environment and the community in case of an emergency.
With its historical significance and crucial role in providing recreational opportunities, Eddy Pond Dam stands as a testament to the intersection of water resource management and climate resilience. As climate change continues to impact water systems, it is imperative to monitor and maintain structures like Eddy Pond Dam to ensure their continued functionality in the face of evolving environmental challenges. The dedication to proper regulation and risk assessment underscores the commitment to preserving this valuable water resource for future generations of enthusiasts and conservationists alike.

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.
