Summary
Standing at a height of 22.2 feet and stretching 1940 feet in length, the dam provides a storage capacity of 58 acre-feet and covers a surface area of 12 acres. The dam, completed in an unspecified year, serves as a crucial recreational spot in Passaic County, accommodating activities such as boating, fishing, and picnicking for local residents and tourists.
Despite its low hazard potential and fair condition assessment as of July 2012, Pompton Dam undergoes inspections every four years to ensure its structural integrity and safety. The dam is equipped with emergency action plans and contacts, although the specifics of their preparation and adherence to guidelines are not provided in the available data. With its role in flood control and water management on the Ramapo River, Pompton Dam contributes to the environmental and recreational landscape of the region, attracting visitors to enjoy its serene waters and picturesque surroundings.
Managed by the New Jersey Department of Environmental Protection (NJDEP), Pompton Dam stands as a testament to responsible water resource management and recreational infrastructure in the state. Its location in the Philadelphia District of the US Army Corps of Engineers and within Congressional District 11 of New Jersey underscores its significance as a vital component of the local water management system. As climate change impacts water resources, the maintenance and upkeep of dams like Pompton Dam become increasingly crucial in ensuring the sustainable utilization of water for recreational and environmental purposes in the face of changing climatic conditions.

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.
