Summary

This earth-type dam stands at 34 feet high and spans 350 feet in length, with a storage capacity of 354 acre-feet. The dam, situated on Halfway Creek, has a spillway width of 3 feet and a maximum discharge of 190 cubic feet per second.

Despite its age, Wilkie Reservoir Dam has been well maintained, with a satisfactory condition assessment as of December 2016. The dam is inspected every two years, with the last inspection conducted in July 2019. The hazard potential of the dam is considered high, although the overall risk assessment is moderate. The dam is regulated by the New York State Department of Environmental Conservation (NYS DEC) and meets state permitting, inspection, and enforcement requirements.

For water resource and climate enthusiasts, Wilkie Reservoir Dam is a noteworthy structure that plays a vital role in the water supply infrastructure of Warren County, New York. With its historical significance and ongoing regulatory oversight, this dam exemplifies the importance of maintaining and monitoring critical water resources to ensure the safety and sustainability of communities in the face of environmental challenges.

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.
