Summary

This concrete dam stands at a height of 40 feet and has a length of 750 feet, creating a storage capacity of 125 acre-feet with a normal storage level of 95 acre-feet. The dam is situated on the Saw Kill River and is under the jurisdiction of the New York State Department of Environmental Conservation.

Despite its age, the dam is in poor condition and has a significant hazard potential. The last inspection in June 2019 revealed the need for maintenance and rehabilitation. The dam is uncontrolled with a spillway width of 130 feet, allowing for a maximum discharge of 14,200 cubic feet per second. The risk assessment for the dam is moderate, with a current risk rating of 3.

With its historical significance and potential risks, the Kingston Reservoir #2 Dam serves as a critical structure for water resource management and climate resilience efforts in the region. Ongoing monitoring, maintenance, and risk management measures are essential to ensure the safety and integrity of this important infrastructure for both recreational and environmental purposes.

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.
