Summary

Built in 1947, this private-owned earth dam stands at a height of 11.5 feet and has a storage capacity of 611 acre-feet, providing ample opportunities for boating, fishing, and other outdoor activities on its 73.5-acre surface area.

Managed by the NHDES Dam Bureau, Smith Pond Dam is state-regulated and regularly inspected to ensure its structural integrity and safety. Despite its high hazard potential, the dam is in satisfactory condition and meets emergency action plan guidelines. With a moderate risk assessment rating, the dam continues to be a popular destination for both locals and visitors seeking to enjoy the beauty and tranquility of Smith Pond Brook.

As part of the New England District and New York District, Smith Pond Dam remains a significant feature in the Grafton County landscape, offering a picturesque setting for nature enthusiasts and outdoor adventurers. Its uncontrolled spillway, along with a drainage area of 0.65 square miles, contributes to the dam's functionality and resilience in managing water flow.

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.
