Summary

The dam stands at a height of 25 feet and spans a length of 450 feet, with a storage capacity of 75 acre-feet. Situated on the Honey Run Beaver Brook, the dam serves as a popular spot for outdoor enthusiasts seeking to enjoy the 15-acre surface area for recreational activities such as fishing, boating, and picnicking.

Managed by the New Jersey Department of Environmental Protection (NJDEP), Lake Barylick Dam is regularly inspected to ensure its structural integrity and public safety. Despite being classified as a low hazard potential structure, the dam's condition assessment is currently listed as "Not Rated." With a maximum discharge capacity of 380 cubic feet per second, the dam plays a crucial role in flood control and water resource management in the region.

While the dam has not undergone any significant modifications in recent years, its emergency action plan (EAP) status and risk assessment measures are not fully documented. As a vital component of the local water infrastructure, Lake Barylick Dam serves as a testament to the importance of responsibly managing water resources in the face of changing climate conditions. With its picturesque surroundings and recreational opportunities, the dam continues to be a valued asset for both locals and visitors alike.

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.
