Summary

This privately owned earth dam stands at a height of 5.5 feet and has a length of 300 feet, with a storage capacity of 49 acre-feet. Despite its primary purpose for recreation, the dam has a high hazard potential and is currently assessed to be in poor condition as of the last inspection in March 2018.

The dam, regulated by the New Jersey Department of Environmental Protection (NJDEP), is situated in Congressional District 02 and is overseen by Representative Jeff Van Drew. It has a drainage area of 8.1 square miles and a maximum discharge capacity of 400 cubic feet per second. The dam's condition assessment in 2018 revealed a need for improvement, and with a hazard potential classified as high, there is a call for enhanced risk management measures to ensure the safety of the surrounding area and water resources.

As a significant feature in the water resource and climate landscape of New Jersey, Jericho Pond Dam stands as both a recreational spot and a critical infrastructure requiring attention and maintenance to mitigate potential risks and ensure long-term stability for the community and environment it serves.

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.
