Summary
Completed in 1965, this concrete dam stands at a height of 8 feet and spans a length of 50 feet, creating a reservoir with a normal storage capacity of 2400 acre-feet. Culvers Lake Dam is situated on Culvers Creek, within the Philadelphia District and Congressional District 05 of New Jersey, under the regulatory oversight of the NJDEP.
Despite its low hazard potential, Culvers Lake Dam maintains a satisfactory condition assessment as of its last inspection in June 2018, with an inspection frequency of every 4 years. The dam's Emergency Action Plan (EAP) was last revised in July 2007, indicating a proactive approach to emergency preparedness. While no inundation maps or risk assessments have been reported, Culvers Lake Dam continues to be a vital resource for water-based recreational activities in the Sussex County area.
With its picturesque location in FRANKFORD TOWNSHIP, Culvers Lake Dam stands as a testament to the importance of maintaining and regulating water resources for both safety and enjoyment. As climate change impacts water availability and quality, structures like Culvers Lake Dam play a crucial role in managing and preserving these valuable natural assets for future generations of water resource and climate enthusiasts.

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.
