Summary

The dam stands at a height of 9 feet and has a length of 220 feet, with a storage capacity of 90 acre-feet. Despite being classified as having a low hazard potential, the dam is considered to be in fair condition as of the last inspection in April 2017.

Managed by the New Jersey Department of Environmental Protection (NJDEP), Coxhat Pond Dam is subject to state regulation, inspection, and enforcement. The dam's emergency action plan status and risk assessment are currently unknown, but its moderate storage capacity and surface area of 10 acres make it an important water resource for the local area. With a drainage area of 3.1 square miles, the dam plays a role in regulating water flow and providing recreational opportunities for the community.

As a landmark in Quinton Township, Coxhat Pond Dam serves as a focal point for outdoor activities and wildlife habitat along the Deep Run river. Despite its relatively small size, the dam plays a vital role in water resource management and climate resilience efforts in Salem County, New Jersey. Its continued maintenance and monitoring ensure the safety and sustainability of the surrounding ecosystem and recreational amenities for future generations to enjoy.

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.
