Summary

This privately owned dam on the Long Branch-Tr River is primarily used for recreational purposes, providing a serene environment for locals and visitors to enjoy. With a hydraulic height of 16.5 feet and a structural height of 19 feet, the dam's presence adds to the natural beauty of the area.

Despite serving as a recreational destination, Audubon Parc Dam has a high hazard potential, emphasizing the importance of proper maintenance and inspection. The dam, with a storage capacity of 8.1 acre-feet and a drainage area of 23 square miles, requires regular monitoring to ensure its structural integrity and safety. While the condition assessment is currently not rated, the last inspection in December 2019 indicated the need for ongoing attention and potential risk management measures.

As water resource and climate enthusiasts explore the intricacies of Audubon Parc Dam, its significance in water management and recreational activities becomes evident. With a blend of natural beauty and functional purpose, this dam is a vital component of the local landscape, highlighting the importance of responsible stewardship and maintenance to preserve its value for future generations.

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.
