Summary

This dam, standing at 6 feet high and 150 feet long, helps create a surface area of 15 acres for recreational activities. It is located in Vernon Township along the Wawayanda Creek-TR, under the regulatory oversight of the New Jersey Department of Environmental Protection (NJDEP).

Despite being a small dam, the South Barry Lake Dike has a significant hazard potential and is subject to regular inspections to ensure its satisfactory condition. The last inspection took place in June 2021, with a scheduled inspection frequency of every two years. The dam has no associated structures and does not fall under the jurisdiction of any federal agency, making it solely under state regulatory control.

The South Barry Lake Dike serves as a vital recreational resource in the area, offering opportunities for boating, fishing, and other water-based activities. As a water resource and climate enthusiast, understanding the infrastructure and regulatory aspects of dams like South Barry Lake Dike can provide valuable insights into the management of water resources and the importance of maintaining these structures for both safety and recreation.

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.
