Summary

Built in 1982, this earth dam stands at a height of 9 feet and stretches over 400 feet in length. It serves a primary purpose of managing sewage and water storage, with a maximum capacity of 9 acre-feet.

The dam is regulated by the NHDES DAM BUREAU and undergoes regular inspections to ensure its structural integrity and safety. Despite its significant hazard potential, the condition assessment in 2016 deemed it satisfactory. The dam's risk assessment is classified as high, highlighting the importance of ongoing risk management measures to mitigate potential threats.

For water resource and climate enthusiasts, the Meriden Village Sewage Lagoon Dam presents an intriguing case study in local government water infrastructure. Its location in Sullivan County, New Hampshire, and its significance in sewage and water storage make it a critical piece of the region's water management system. With its history, design, and risk assessment, this dam serves as a noteworthy example of the intersection between infrastructure, environmental stewardship, and public safety 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.
