Summary

Completed in 1977, this earth dam stands at 29 feet high and stretches 440 feet in length, serving the primary purpose of flood risk reduction along the Farm Brook. With a storage capacity of 10 acre-feet and a spillway width of 15 feet, this dam plays a vital role in mitigating flood hazards in the area.

Managed by the state regulatory agency DEEP, Farm Brook Flood Control Site #2a Dam is considered to have a high hazard potential but is currently in satisfactory condition, as assessed in 2015. Despite its age, the dam meets inspection, permitting, and enforcement requirements, ensuring its effectiveness in flood risk reduction. The risk assessment for this structure is moderate, indicating a level 3 risk, and while no emergency action plan (EAP) details are provided, the dam's overall risk management measures are currently not specified.

Located in New Haven County, Farm Brook Flood Control Site #2a Dam stands as a significant component of flood control infrastructure in the region, serving as a testament to the ongoing efforts to manage water resources and mitigate the impacts of climate change. With its strategic design and regulatory oversight, this dam remains a critical asset in safeguarding the local community from potential flooding events along the Farm Brook.

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.
