Summary

Completed in 1986, the dam stands at a height of 12 feet and has a length of 100 feet, with a storage capacity of 204 acre-feet. The dam regulates the flow of Smith Brook and has a low hazard potential, with a satisfactory condition assessment as of December 2016.

Managed by the NHDES Dam Bureau, Black Fox Pond Dam is subject to state regulation, permitting, inspection, and enforcement, ensuring its safety and compliance with standards. The dam features an uncontrolled spillway with a width of 8 feet, and a drainage area of 0.49 square miles. Despite its moderate risk assessment, the dam is considered safe for recreational use and has not undergone any major modifications since its completion.

With its scenic location and essential role in providing recreational opportunities, Black Fox Pond Dam serves as a vital asset for the community in Hillsborough County, New Hampshire. Enthusiasts interested in water resources and climate will appreciate the detailed information available on the dam's design, construction, and maintenance, highlighting the intersection of human engineering with natural landscapes in the region.

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.
