Summary
The dam stands at a height of 4 feet and has a storage capacity of 2.4 acre-feet, providing a surface area of 0.6 acres for recreational activities. Despite being classified as having a "Fair" condition assessment and a "Significant" hazard potential, the dam is regularly inspected by state authorities to ensure its safety.
Managed by the Connecticut Department of Energy and Environmental Protection (DEEP), Green Acre Lane Pond Dam has been deemed state-regulated, with permits, inspections, and enforcement measures in place to guarantee compliance with safety standards. The dam, constructed without federal funding or oversight, falls under the jurisdiction of the New England District of the US Army Corps of Engineers. While no modifications or enhancements have been recorded since the last inspection in 2016, the dam continues to serve as a vital recreational resource for the local community, under the watchful eye of state regulators and officials.
With its tranquil waters and scenic surroundings, Green Acre Lane Pond Dam offers a peaceful retreat for water resource and climate enthusiasts alike. As a privately-owned structure with a focus on recreation, the dam plays a significant role in providing a safe and enjoyable environment for outdoor activities. While maintaining a balance between conservation and public enjoyment, state agencies ensure that the dam remains in a fair condition and adheres to regulatory guidelines, safeguarding both the environment and the community it serves.

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.
