Summary

This earth dam stands at a height of 12 feet and has a hydraulic height of 7.3 feet, creating a reservoir with a maximum storage capacity of 70 acre-feet. The dam, situated on the Rumford River, covers a surface area of 7.7 acres and serves as a recreational spot for water resource and climate enthusiasts in the area.

Managed by the Department of Conservation and Recreation in Massachusetts, Kingman Pond Dam is state regulated and inspected, with a satisfactory condition assessment as of June 2014. The dam poses a significant hazard potential but is deemed to have moderate risk management measures in place. Despite being uncontrolled, the spillway type and structural design of the dam contribute to its overall safety and functionality. The dam's location and features make it a significant point of interest for those interested in water resource management and climate conservation efforts in the region.

With a notable association with the New England District of the US Army Corps of Engineers, Kingman Pond Dam serves as a vital component of the local water infrastructure. Its construction and design reflect a commitment to both recreational enjoyment and environmental stewardship. The dam's presence on the Rumford River not only provides a picturesque setting for visitors but also contributes to the conservation and management of water resources in Bristol County. For water resource and climate enthusiasts, Kingman Pond Dam represents a harmonious blend of human intervention and natural beauty that highlights the importance of sustainable practices in water management.

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.
