Summary
Completed in 1990, the earth dam stands at a height of 11 feet and stretches for 1050 feet, creating a reservoir with a storage capacity of 182 acre-feet. The dam is situated on Barton's Run-TR and is regulated by the New Jersey Department of Environmental Protection, with regular inspections ensuring its safe operation.
Despite being classified as having a significant hazard potential, Lake James Dam is currently assessed to be in fair condition as of the last inspection in October 2020. The dam's emergency action plan was last revised in August 2018, and it meets established guidelines. With a maximum discharge capacity of 360 cubic feet per second, the dam plays a crucial role in managing water resources in the area, with a drainage area of 0.6 square miles and a surface area of 35 acres.
Lake James Dam provides not only recreational opportunities but also serves as a crucial infrastructure element in Evesham Township. With its strategic location and regulatory oversight, the dam plays a vital role in water resource management and climate resilience efforts in the region.

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.
