Summary

Standing at a height of 13 feet with a hydraulic height of 9 feet, the dam holds a maximum storage capacity of 200 acre-feet, with a normal storage level of 72 acre-feet. The primary purpose of the dam is for recreation, attracting enthusiasts of water resources and climate to enjoy its tranquil surroundings.

Despite its age, Bents Pond Dam has been well-maintained and is regulated by the Department of Conservation and Recreation in Massachusetts. With a low hazard potential and a satisfactory condition assessment, the dam presents a moderate risk, according to a recent assessment. While there are no associated structures or locks, the dam's uncontrolled spillway ensures proper discharge of water, maintaining safety and efficiency for nearby residents and visitors.

For water resource and climate enthusiasts, Bents Pond Dam offers a glimpse into the history of water management in Massachusetts while providing a recreational space for outdoor activities. With its tranquil setting and well-maintained condition, the dam stands as a testament to responsible stewardship and serves as a vital component of the local water supply infrastructure.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
