Summary

Completed in 1934, this earth dam stands at a height of 25 feet and stretches 400 feet in length, with a storage capacity of 28 acre-feet and a maximum discharge rate of 170 cubic feet per second. The dam, designed primarily for water supply purposes, overlooks TR Lake Waukewan and covers a surface area of 3 acres within a drainage area of 0.17 square miles.

Despite its low hazard potential, the dam is regulated, permitted, inspected, and enforced by the NHDES Dam Bureau, ensuring compliance with state safety standards and guidelines. With a moderate risk assessment rating, the dam's condition is currently not rated, and no emergency action plan has been prepared or updated. While the dam's risk management measures are unspecified, its controlled by an uncontrolled spillway with a width of 14 feet. Overall, Meredith Reservoir Dam stands as a crucial infrastructure supporting water supply needs in the region, warranting ongoing monitoring and maintenance to ensure its safety and functionality.

Enthusiasts of water resources and climate in the area can appreciate Meredith Reservoir Dam for its historical significance, engineering design, and essential role in water management. The dam's location within Belknap County, New Hampshire, underscores its importance in sustaining local water resources and serving the community's needs. As a key structure under state jurisdiction, the dam's operation and maintenance by the local government emphasize the commitment to ensuring water supply reliability and safety for residents. With its moderate risk assessment, the dam presents an opportunity for continuous evaluation and improvement to mitigate potential hazards and enhance its resilience in the face of changing climate 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.
