Summary

With a height of 24 feet and a length of 220 feet, the dam serves primarily for recreational purposes, providing a surface area of 4 acres and a storage capacity of 52 acre-feet. The dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.

Managed by the New York State Department of Environmental Conservation (NYS DEC), Klein Pond Dam is regulated, permitted, inspected, and enforced by the state agency. The dam features an uncontrolled spillway with a width of 21 feet and a maximum discharge capacity of 215 cubic feet per second. Despite being last inspected in 1994 and not having a recent condition assessment, the dam poses a moderate risk level with a moderate risk management rating of 3, suggesting that further evaluation and potential maintenance may be needed to ensure its safety and operational integrity for the surrounding community and ecosystem along TR-KLEIN KILL.

For water resource and climate enthusiasts, Klein Pond Dam presents an interesting case study in dam infrastructure management and risk assessment. With its picturesque location and recreational purpose, the dam serves as a vital component in the local environment while also requiring ongoing attention to maintain its safety and functionality. The involvement of the NYS DEC in overseeing its operation highlights the importance of state agencies in ensuring the sustainability and resilience of water infrastructure in the face of changing climate conditions and evolving regulatory standards.

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.
