Summary

With a height of 13 feet and a length of 225 feet, the dam serves as a popular spot for outdoor activities in Ocean Township. The dam has a storage capacity of 235 acre-feet, with a normal storage level of 35 acre-feet and a surface area of 2 acres.

Managed by the local government, Wickapecko Dam is regulated and inspected by the New Jersey Department of Environmental Protection. Despite its low hazard potential, the dam's condition is currently not rated, with the last inspection conducted in 2001. The dam does not have an Emergency Action Plan in place, and there are no existing risk assessment or management measures documented.

Water resource and climate enthusiasts will find Wickapecko Dam an interesting site to explore, given its historical significance and recreational purpose. As a key component of the Hollow Brook river system, the dam provides valuable insights into local water management practices and the importance of maintaining infrastructure for both safety and environmental sustainability. Visitors can appreciate the beauty of the surrounding area while learning about the dam's role in water storage and flood control within Monmouth County, New Jersey.

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.
