Summary

Built in 1922, this earth dam stands at a height of 19 feet and spans 250 feet in length, creating a reservoir with a normal storage capacity of 86 acre-feet. Situated on Raccoon Creek and within the Baltimore District of the US Army Corps of Engineers, this dam is owned and regulated by the state of New Jersey, specifically by the NJ Department of Environmental Protection.

With a hazard potential classified as significant but a condition assessment deemed satisfactory as of April 2021, Mullica Hill Pond Dam is subject to biennial inspections to ensure its structural integrity. Despite lacking certain features like spillways or outlet gates, the dam continues to serve its primary purpose of recreation, offering a surface area of 10 acres for outdoor enjoyment. The dam's EAP (Emergency Action Plan) status is currently unclear, but its compliance with state regulations and inspection standards underscores its commitment to public safety and environmental stewardship.

As the sole dam associated with Mullica Hill Pond, this structure not only provides opportunities for leisure activities but also plays a crucial role in managing water resources and enhancing the natural landscape of Gloucester County, New Jersey. As water enthusiasts explore the area and appreciate the beauty of Raccoon Creek, the Mullica Hill Pond Dam stands as a testament to the intersection of human ingenuity and environmental conservation in preserving our precious waterways for generations to come.

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.
