Summary

Built in 1880, this earth dam stands at a height of 12 feet and stretches 200 feet in length, creating a surface area of 24.6 acres and a drainage area of 1.3 square miles. The dam has a maximum storage capacity of 80 acre-feet and a maximum discharge rate of 140 cubic feet per second.

Despite being classified as having a "Fair" condition assessment, Shaker Pond Dam poses a significant hazard potential due to its outdated spillway type of "Uncontrolled." The dam is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP), which ensures that it undergoes regular inspections, with the last inspection conducted in August 2019. The dam's emergency action plan (EAP) status, risk assessment, and risk management measures are currently not explicitly specified in the available data.

Given its historical significance and the potential risks associated with its current condition, Shaker Pond Dam serves as a critical site for water resource and climate enthusiasts to monitor and advocate for proper maintenance and safety measures to protect the surrounding community and environment. The dam's location on the Jawbuck Brook, its association with recreation, and its significant hazard potential highlight the importance of ongoing oversight and proactive risk management to ensure the continued safety and sustainability of this iconic structure.

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.
