Dickerman Pond Dam Reservoir Report

Last Updated: December 16, 2025

Dickerman Pond Dam, located in New Hampton, New Hampshire, was completed in 1934 and serves multiple purposes including fire protection and as a stock or small fish pond.

Summary

The dam stands at a height of 20 feet with a length of 200 feet, creating a reservoir with a storage capacity of 25 acre-feet. However, despite its functional importance, the dam is currently assessed as being in poor condition with a significant hazard potential.

The dam is regulated by the New Hampshire Department of Environmental Services Dam Bureau, with state permitting, inspection, and enforcement mechanisms in place. The last inspection was conducted in May 2019, with an inspection frequency of 4 years. The risk assessment for Dickerman Pond Dam indicates a moderate risk level, with measures for risk management yet to be specified. With its earth structure and uncontrolled spillway, the dam presents an intriguing case study for water resource and climate enthusiasts interested in the maintenance and management of aging infrastructure in the face of changing environmental conditions.

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.
