Summary
This Earth-type dam stands at a height of 22 feet and spans 300 feet in length, with a storage capacity of 300 acre-feet. The primary purpose of this dam is for recreation, providing a tranquil environment for visitors to enjoy water activities and scenic views. Despite its significant hazard potential, the dam's condition assessment is deemed satisfactory as of the last inspection in December 2020.
Managed by the New Jersey Department of Environmental Protection (NJDEP), Forest Hill Park Dam is state-regulated, inspected, and enforced to ensure public safety and environmental protection. With a drainage area of 0.25 square miles, the dam serves as a critical infrastructure for managing water resources in the region. While there are no associated structures or federal involvement, the dam's compliance with state regulations and inspection frequency of every 2 years demonstrate a commitment to maintaining its integrity and functionality.
For water resource and climate enthusiasts, Forest Hill Park Dam serves as a notable recreational feature along the Pequannock River-TR. Its Earth-type construction, satisfactory condition assessment, and state regulatory oversight highlight the importance of responsible dam management in preserving natural habitats and safeguarding communities from potential hazards. With its location in Passaic County, New Jersey, this dam represents a balance between human recreation and environmental stewardship in a changing climate landscape.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
