Summary
Owned and regulated by the Connecticut Department of Energy and Environmental Protection (DEEP), this earth dam stands at a height of 30 feet and spans 680 feet in length, with a storage capacity of 110 acre-feet. Situated along an unnamed river or stream, the dam's primary purpose is to ensure a reliable water supply for the local community.
With a significant hazard potential, Taftville Reservoir #2 Dam has not been rated for its condition since its last inspection in October 2008. The dam's spillway width measures at 12 feet, and it has a maximum discharge of 10 cubic feet per second. While the dam has not been modified in recent years, it is crucial to ensure regular inspections and maintenance to mitigate any potential risks associated with its aging infrastructure. The dam's emergency action plan (EAP) status and compliance with guidelines remain unspecified, highlighting the importance of proactive risk management measures to safeguard the surrounding area in case of emergencies.
As a key component of the local water supply system, Taftville Reservoir #2 Dam plays a vital role in supporting the community's water needs. With its location in New London County, Connecticut, and under the jurisdiction of the DEEP, this dam exemplifies the importance of effective regulatory oversight and maintenance practices to ensure its continued reliability and safety for both water resource management and climate resilience efforts in the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
