Summary
This concrete buttress dam stands at a height of 10 feet and stretches 34 feet in length, completed in 1934. With a storage capacity of 82 acre-feet, the dam serves as a recreational spot with a surface area of 14.5 acres and a drainage area of 0.43 square miles.
Despite its low hazard potential and satisfactory condition assessment, Lime Pond Dam is subject to regular inspections by the NHDES Dam Bureau to ensure its safety and compliance with state regulations. The spillway of the dam is uncontrolled with a width of 2 feet, capable of discharging a maximum volume of 182 cubic feet per second. The risk assessment for the dam is classified as moderate, indicating a need for ongoing risk management measures to mitigate potential hazards and ensure the safety of the surrounding area.
Water resource and climate enthusiasts may find Lime Pond Dam an interesting case study for its recreational significance, structural design, and regulatory oversight. As a part of the New England District, this dam not only provides leisure opportunities but also serves as a vital component of the local ecosystem and water management system. With its location in a picturesque setting in Coos County, New Hampshire, Lime Pond Dam presents a unique blend of natural beauty and engineered infrastructure that merits attention and appreciation from those interested in water resources and climate resilience.

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.
