Summary

With a dam height of 9.8 feet and a length of 500 feet, this earth dam provides a normal storage capacity of 73 acre-feet and covers a surface area of 20 acres. Despite not having a designated year of completion, the dam is actively monitored and inspected by the state regulatory agency, DEEP, with a hazard potential rated as significant.

Owned by the state of Connecticut, Great Meadow Brook Pd serves as a hub for outdoor recreation activities in the New London County area. Its primary purpose is for recreational use, with the dam offering opportunities for fishing, boating, and wildlife observation. The dam's spillway width of 24 feet ensures proper water flow management, and its location in a scenic natural setting makes it a popular destination for water resource and climate enthusiasts alike.

Although the dam's condition assessment is currently listed as "Not Rated," the Emergency Action Plan (EAP) was last revised in 2005 to ensure the safety and preparedness of the surrounding community in case of emergencies. With its significant hazard potential and state-regulated status, Great Meadow Brook Pd stands as a vital piece of infrastructure for both recreation and water resource management in Connecticut.

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.
