Summary

With a height of 16 feet and a length of 208 feet, the dam provides a maximum storage capacity of 59 acre-feet and a normal storage of 28 acre-feet. Its uncontrolled spillway, 170 feet wide, ensures the safe management of water flow during periods of high discharge.

Managed by a private entity and regulated by the New York State Department of Environmental Conservation, Juengst Dam has a low hazard potential and a moderate risk assessment rating. Despite being in operation for over a century, the dam's condition assessment is currently not rated, with the last inspection conducted in March 2017. While the dam meets regulatory guidelines, there is no Emergency Action Plan in place, suggesting potential areas for improvement in emergency preparedness and risk management.

For water resource and climate enthusiasts, Juengst Dam serves as a fascinating example of historical engineering that continues to play a vital role in recreational activities and water management in the region. As discussions around dam safety and environmental protection evolve, monitoring and maintenance of structures like Juengst Dam will be crucial to ensuring the safety and sustainability of our water resources in the face of changing climate 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.
