Summary

This concrete structure stands at a height of 14 feet and spans a length of 325 feet, creating a surface area of 2.3 acres. While its primary purpose is for recreation, the dam is also regulated by the Connecticut Department of Energy and Environmental Protection (DEEP) and undergoes regular inspections to ensure its safety.

Situated on the Naugatuck River Tributary, May Street North Pond Dam plays a crucial role in managing water resources in the area. With a significant hazard potential and a condition assessment that is currently not rated, the dam poses challenges that require careful monitoring and maintenance. The last inspection was conducted in December 2014, with an inspection frequency of every 5 years.

For water resource and climate enthusiasts, May Street North Pond Dam presents an interesting case study in dam management and safety. Its location in New Haven County, Connecticut, highlights the importance of maintaining infrastructure to support recreational activities while also safeguarding against potential risks and hazards. As efforts continue to enhance the dam's safety and resilience, ongoing attention to its condition and regulatory compliance will be essential to ensure the continued protection of the surrounding community and environment.

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.
