Summary

Owned by the local government, this earth dam stands at a height of 20 feet and has a storage capacity of 144 acre-feet, with a normal storage level of 89 acre-feet. With a low hazard potential and not yet assessed for condition, the dam serves as a critical piece of infrastructure in mitigating the impacts of flooding in the area.

Managed by the New York State Department of Environmental Conservation, the dam is regulated, permitted, inspected, and enforced by the state. While it was last inspected in October 1993 and considered to have a moderate risk level, there have been no recent modifications or assessments of its condition. With an uncontrolled spillway and a maximum discharge capacity of 116 cubic feet per second, the dam plays a vital role in protecting the surrounding area from potential flood events.

Despite its age and lack of recent evaluations, the Lesky Road Flood Control Dam remains a key component in the flood risk reduction strategy for the region. With its moderate risk level and low hazard potential, the dam continues to serve its primary purpose effectively. As water resource and climate enthusiasts, understanding and monitoring the condition and functionality of such infrastructure is essential to ensuring the safety and resilience of communities in the face of changing environmental 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.
