Summary
The dam, standing at a height of 10 feet with a hydraulic height of 8.5 feet, holds a storage capacity of 42 acre-feet and covers a surface area of 5 acres within its drainage area of 20.7 acres. The dam's construction on the Assonet River reflects a controlled spillway type, emphasizing its critical role in managing water resources in the region.
Despite its historical significance and functional purpose, Monument Pond Dam poses a high hazard potential with an overall unsatisfactory condition assessment, indicating the need for immediate attention and potential risk management measures. The dam is under state regulation by the Department of Conservation and Recreation, with state permitting, inspection, and enforcement in place to ensure compliance with safety standards. The dam's location in Freetown highlights its importance in water resource management and underscores the need for proactive maintenance to mitigate potential risks associated with its structural integrity.
As water resource and climate enthusiasts monitor the condition of Monument Pond Dam, it is crucial to recognize the very high risk level assigned to this structure, emphasizing the need for regular inspection and potential emergency action planning. With Joseph P. Kennedy III serving as the representative for the New England District where the dam is situated, stakeholders must remain vigilant in addressing the dam's challenges to safeguard the surrounding community and environment. By staying informed and advocating for proper maintenance and risk mitigation strategies, enthusiasts can play a vital role in preserving the integrity and functionality of Monument Pond Dam for generations to come.

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.
