Summary

Managed by the Middletown Township, this earth-type dam on the Navesink River-TR is regulated by the New Jersey Department of Environmental Protection (NJDEP) and meets state inspection and enforcement requirements. The dam has a significant hazard potential but is currently in satisfactory condition as of the last assessment in December 2021.

Although specific details on the dam's height, volume, and completion year are not provided, its surface area covers 1 acre with a drainage area of 0.24 square miles. The dam does not have a spillway or outlet gates, and there is no information on associated structures or modifications over the years. The last inspection in December 2021 deemed the dam's condition satisfactory, with an inspection frequency of 2 and an emergency action plan (EAP) last revised in September 2019.

For water resource and climate enthusiasts, the Navesink River Road Dam offers a unique opportunity for recreational activities while also serving as a critical piece of infrastructure in the region. With its location along the Navesink River-TR and state-regulated status, the dam plays a role in managing water flow and supporting local ecosystems. As efforts continue to monitor and maintain the dam's safety, it remains a focal point for both residents and environmental officials in ensuring its continued function for the community.

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.
