Summary
Standing at a height of 18 feet and stretching 85 feet in length, this dam serves a primary purpose of "Other," with a fair condition assessment as of August 2018. Despite its modest size, Pound Pond Dam is deemed to have a significant hazard potential, warranting regular inspections every five years to ensure its structural integrity and public safety.
Managed by the Connecticut Department of Energy and Environmental Protection (DEEP), Pound Pond Dam is subject to state regulations, permitting, inspection, and enforcement. While the dam currently holds a normal storage capacity of zero and lacks detailed information on its storage volume and discharge capabilities, its spillway measures 10 feet in width. The last inspection conducted in August 2018 deemed the dam's condition as fair, suggesting a need for ongoing monitoring and potential maintenance to address any safety concerns.
With its picturesque location in Fairfield County, Pound Pond Dam serves as a crucial structure for managing water resources and mitigating flood risks in the region. As climate change continues to impact weather patterns and water levels, the maintenance and monitoring of dams like Pound Pond become increasingly vital to ensure their effectiveness in safeguarding communities and ecosystems. Enthusiasts of water resources and climate resilience will find Pound Pond Dam to be a fascinating case study in the intersection of infrastructure management, environmental stewardship, and public safety.

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.
