Summary

Completed in 1941, this earth dam stands at a height of 14 feet and has a length of 265 feet, providing a storage capacity of 160 acre-feet. The dam's primary purpose is recreation, offering a surface area of 24 acres for water enthusiasts to enjoy.

Despite its historical significance and recreational value, Lake Pine Dam has been flagged with a significant hazard potential and poor condition assessment during its last inspection in July 2019. The dam is regulated by the New Jersey Department of Environmental Protection, ensuring state permitting, inspection, and enforcement protocols are adhered to. The dam's emergency action plan was last revised in 2013, highlighting the need for updated risk assessment and management measures to ensure the safety of its surrounding community.

The dam's location within the Burlington County, New Jersey, underlines the importance of maintaining its structural integrity and conducting regular inspections to mitigate any potential risks. As climate change continues to impact water resources, enthusiasts and stakeholders must stay informed about the condition of Lake Pine Dam and advocate for necessary improvements to safeguard its recreational and environmental significance for future generations.

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.
