Summary

This earth-type dam stands at a height of 10 feet with a length of 200 feet, providing a surface area of 25 acres and a drainage area of 26.5 square miles. The primary purpose of this dam is for recreation, offering a storage capacity of 166 acre-feet.

Despite being classified with a low hazard potential and currently not rated for its condition, Caines Mill Pond Dam is regulated by the New Jersey Department of Environmental Protection (NJDEP) and undergoes regular state inspections. With a designated inspection frequency of 4, this dam ensures compliance with state regulations and enforcement measures. While details on its construction year, maximum storage, and spillway type are not specified, the dam remains a notable feature within the natural landscape of Atlantic County, New Jersey.

Water resource and climate enthusiasts interested in the management and maintenance of dams will find Caines Mill Pond Dam to be a fascinating subject of study. Its location, design characteristics, and regulatory oversight by NJDEP offer valuable insights into the importance of monitoring and ensuring the safety of such structures. As part of the broader network of dams in the region, Caines Mill Pond Dam contributes to water storage capabilities and recreational opportunities while highlighting the need for ongoing assessment and risk management strategies in the face of changing environmental conditions.

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.
