Summary

The dam stands at a height of 8 feet and has a length of 120 feet, with a storage capacity of 522 acre-feet. Despite its modest size, the dam poses a significant hazard potential with a poor condition assessment, indicating the need for regular inspections and maintenance.

Managed by the NHDES Dam Bureau, Dube Pond Dam is situated on Maple Falls Brook within the Merrimack County of New Hampshire. The dam's spillway type is uncontrolled, with a spillway width of 10 feet, and a drainage area of 6.24 square miles. The surrounding area offers a surface area of 104 acres for recreational activities, with a normal storage capacity of 200 acre-feet. The dam's risk assessment is moderate, emphasizing the importance of ongoing risk management measures to ensure public safety.

In light of its condition and hazard potential, Dube Pond Dam serves as a crucial point of interest for water resource and climate enthusiasts. As a key component of the local ecosystem, it is essential to monitor and address any potential risks associated with the dam to safeguard both the environment and the surrounding communities.

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.
