Summary

This masonry dam stands at a height of 18 feet and stretches 200 feet in length, holding a surface area of 3 acres within its boundaries. While its normal storage capacity is rated at zero, the dam is considered significant in terms of hazard potential, although its condition assessment remains unrated.

Owned privately, the Red Mill Pond Dam falls under state regulation, with the Department of Energy and Environmental Protection (DEEP) overseeing its permitting, inspection, and enforcement processes. Despite its last inspection dating back to 2003, the dam's inspection frequency is set at 5 years, reflecting a commitment to ensuring its structural integrity and safety. With Joe Courtney (D) representing the area in Congress, the dam's role in water resource management and climate resilience remains integral to the local community and surrounding environment.

In the realm of water resource and climate enthusiasts, the Red Mill Pond Dam stands as a key feature in the New London, Connecticut landscape, holding historical significance and functional relevance in the region. As efforts to assess and manage its risk potential continue, the dam serves as a reminder of the intricate balance between human infrastructure and natural ecosystems, highlighting the importance of ongoing monitoring and maintenance in safeguarding our water resources for future generations.

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.
