Summary

The dam has a height of 16 feet and a length of 255 feet, creating a storage capacity of 160 acre-feet and a surface area of 20 acres. It is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP) and is considered to have a significant hazard potential and fair condition assessment.

The dam, situated on Keach Brook, features an uncontrolled spillway with a width of 100 feet and is equipped with slide (sluice gate) outlet gates. It has a maximum discharge capacity of 2456 cubic feet per second and serves as a popular recreational spot in Windham County, Connecticut. Despite being inspected regularly, the dam's risk assessment is moderate, with a 3 rating, indicating potential vulnerabilities that need to be managed to ensure the safety of the surrounding community and environment.

With its historical significance and importance for water resource management and recreation, Peck Pond Dam stands as a vital infrastructure in the region. It serves as a reminder of the intersection between human intervention in natural landscapes and the need for sustainable practices to mitigate risks associated with dam failure and ensure the long-term preservation of water resources in the area.

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.
