Summary
Misery Dam, located in Pemberton, New Jersey, is a privately owned structure on Mt. Misery Brook. The dam serves primarily for recreational purposes and was completed in 1950, standing at a height of 10 feet and spanning a length of 660 feet. With a storage capacity of 64 acre-feet, the dam covers a surface area of 12 acres and drains a watershed area of 27.5 square miles.
Managed by the New Jersey Department of Environmental Protection (NJDEP), Mt. Misery Dam is classified as a low hazard potential structure with a condition assessment of "Not Rated." The last inspection was conducted in March 2003, with a scheduled frequency of every 4 years. While the dam has not been modified in recent years and lacks specific risk assessment and emergency preparedness measures, its presence contributes to the recreational and ecological landscape of the area, offering opportunities for outdoor activities and scenic enjoyment along Mt. Misery Brook.
To water resource and climate enthusiasts, Mt. Misery Dam represents a unique combination of human intervention in water management and natural beauty. As a privately owned earth dam designed for recreational use, its presence adds to the overall landscape and water resources of Burlington County, New Jersey. With its low hazard potential and state regulatory oversight, the dam remains a symbol of responsible stewardship and engagement with the surrounding environment, showcasing the intersection of human and natural systems in the context of water resource management and climate resilience.

Dam Data Reference
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.
