Summary

The dam is classified as an Earth dam with a height of 10.5 feet and a length of 250 feet, creating a reservoir that has a normal storage capacity of 57 acre-feet. The dam impounds Hohokus Brook and covers a surface area of 7 acres, with a drainage area of 14.8 square miles.

The dam is owned and regulated by the local government, with oversight from the New Jersey Department of Environmental Protection (NJDEP). It is regularly inspected, with the most recent assessment conducted in May 2020, indicating a fair condition and a low hazard potential. The dam has not been significantly modified in recent years and does not have an Emergency Action Plan (EAP) in place. Despite its relatively low risk profile, the dam plays a crucial role in providing recreational opportunities and water resource management for the surrounding area.

Whites Pond Dam is a vital piece of infrastructure that not only supports recreational activities but also contributes to the overall water management strategy in the region. With its historical significance and ongoing maintenance, the dam continues to play a key role in the local community's efforts to balance water resource needs and climate resilience.

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.
