Summary

Completed in 1914, this concrete dam stands at a height of 34 feet and spans 372 feet in length, with a storage capacity of 4 billion gallons. The dam is regulated by the New York State Department of Environmental Conservation and undergoes regular inspections to ensure its structural integrity and safety.

The Wilkie Intake Reservoir Dam plays a significant role in managing water resources and ensuring a reliable water supply for the surrounding area. With a spillway width of 20 feet and a hazard potential rated as significant, the dam is equipped to handle excess water flow and prevent potential flooding. Despite its age, the dam's condition is assessed as satisfactory, and risk management measures are in place to mitigate any potential hazards.

The Wilkie Intake Reservoir Dam stands as a testament to early 20th-century engineering and continues to fulfill its primary purpose of providing essential water supply services to the community. With its historical significance and ongoing maintenance efforts, the dam remains a vital infrastructure asset in the region, safeguarding against water scarcity and supporting sustainable water resource management practices.

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.
