Summary
Built in 1941, this earth dam stands at a height of 13 feet and spans a length of 410 feet, creating a reservoir that stores up to 115 acre-feet of water. The dam's primary purpose is for recreation, offering opportunities for boating, fishing, and other leisure activities in the picturesque setting of Barton Run.
Despite its fair condition assessment, Cedar Lake Dam is classified as having a significant hazard potential, underscoring the importance of regular inspections and maintenance. The dam is regulated by the New Jersey Department of Environmental Protection (NJDEP) and undergoes state permitting, inspection, and enforcement processes to ensure its safety and compliance with regulations. With a maximum discharge capacity of 1304 cubic feet per second, the dam plays a crucial role in managing water flow and protecting downstream areas from flooding.
The dam's proximity to Congressional District 01, represented by Donald Norcross, highlights its significance in water resource management and climate resilience efforts in the region. As water resource and climate enthusiasts, understanding the critical role of infrastructure like Cedar Lake Dam is essential for safeguarding communities and ecosystems in the face of changing weather patterns and increasing water-related risks.

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.
