Summary

Built in 1953, this earth dam stands at a height of 13 feet and stretches 580 feet in length, creating a reservoir with a storage capacity of 1176 acre-feet. The dam is situated on the Pole Bridge Branch river and is regulated by the New Jersey Department of Environmental Protection, with regular inspections to ensure its safety and functionality.

Despite its satisfactory condition assessment, the Country Lake #1 Dam is classified as having significant hazard potential, underlining the importance of ongoing risk management and emergency preparedness. The dam's maximum discharge capacity is 1250 cubic feet per second, with a surface area of 64 acres and a drainage area of 16 square miles. While there have been no reported modifications to the dam in recent years, its last inspection in April 2021 indicated a need for continued monitoring and maintenance to uphold safety standards and prevent potential risks to downstream communities.

As a key recreational asset in Burlington County, New Jersey, Country Lake #1 Dam serves as a popular destination for water resource and climate enthusiasts. With its picturesque surroundings and vital role in providing outdoor recreational opportunities, the dam stands as a testament to the intersection of human infrastructure and natural landscapes, emphasizing the need for sustainable management practices to safeguard our water resources 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.
