Summary

This private dam stands at a height of 28 feet and has a length of 450 feet, providing a surface area of 60 acres for various recreational activities. With a maximum storage capacity of 920 acre-feet and a normal storage level of 630 acre-feet, the dam also boasts a spillway width of 185 feet and a maximum discharge capacity of 6300 cubic feet per second.

Managed by the Connecticut Department of Energy and Environmental Protection (DEEP), Pinewood Lake Dam is classified as having a high hazard potential but is currently in satisfactory condition based on the most recent inspection in October 2020. Despite its age, the dam continues to meet regulatory requirements for state permitting, inspection, and enforcement. While no emergency action plan (EAP) is currently in place, the dam's emergency preparedness and risk management measures are continuously evaluated and updated to ensure the safety of nearby communities in case of a water-related incident.

Pinewood Lake Dam, with its historic masonry construction and significant recreational value, stands as a key water resource in Fairfield County. As water resource and climate enthusiasts, understanding the importance of maintaining and managing dams like Pinewood Lake is crucial for ensuring the safety and sustainability of our water infrastructure in the face of changing environmental conditions and increasing demands for recreational and ecological water use.

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.
