Summary
The dam, standing at a height of 11.2 feet and with a length of 200 feet, creates a tranquil lake that covers a surface area of 30 acres. The dam is situated on the Haynes Creek, within the beautiful surroundings of Burlington County, New Jersey.
Although the dam has a low hazard potential and is currently in satisfactory condition, it is regulated by the New Jersey Department of Environmental Protection (NJDEP) and undergoes regular inspections to ensure its structural integrity and safety. The last inspection, conducted in July 2010, found the dam to be in good condition. With a normal storage capacity of 90 acre-feet, the dam provides a serene setting for water enthusiasts and nature lovers to enjoy recreational activities in the area.
Despite its private ownership, Oliphants Mill Lake Dam plays a crucial role in the local community by offering a peaceful retreat for residents and visitors alike. The dam's importance lies not only in its recreational value but also in its contribution to the overall water resource management in the region. As climate change continues to impact water resources, dams like Oliphants Mill Lake Dam will play a vital role in ensuring the sustainable use of water for future generations.

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.
