Summary
Built in 1965, the dam stands at a height of 28 feet and spans 110 feet in length, creating a storage capacity of 150 acre-feet on the Salmon Brook river. With a primary purpose of recreation, the dam offers a surface area of 12.5 acres for outdoor enthusiasts to enjoy.
Managed by the New Hampshire Department of Environmental Services Dam Bureau, Salmon Brook Dam is regulated, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. The dam's hazard potential is classified as low, with a fair condition assessment. Despite having an uncontrolled spillway type, the risk assessment for the dam is moderate, warranting ongoing risk management measures.
For water resource and climate enthusiasts, Salmon Brook Dam serves as a significant structure in the region, providing recreational opportunities while also highlighting the importance of proper dam management and maintenance. With its picturesque setting and vital role in water storage and management, the dam stands as a reminder of the delicate balance between human needs and environmental preservation in the face of changing climate conditions.

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.
