Summary

The earth dam stands at a height of 10 feet and stretches 350 feet in length, creating a surface area of 4 acres. The dam is state regulated and inspected, with a significant hazard potential but a fair condition assessment as of November 2019.

While Clarks Pond Dam serves as a recreational spot, it also poses a moderate risk level, prompting the need for risk management measures. The spillway type is uncontrolled with a width of 3 feet, and the outlet gates consist of a valve system. The dam has not undergone any significant modifications in recent years, and its last inspection in November 2019 highlighted the importance of maintaining its fair condition to ensure public safety and environmental protection.

Enthusiasts of water resources and climate in the New Haven area may find Clarks Pond Dam an interesting subject for study and monitoring. With its location on Mud Brook and the potential risks associated with its significant hazard level, the dam presents an opportunity to explore the intersection of recreational land use, dam safety, and environmental conservation in the region.

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.
