Summary

This earth dam stands at a height of 12.9 feet and has a normal storage capacity of 40 acre-feet, providing recreational opportunities in its 7-acre surface area. The dam, completed in an unknown year, plays a crucial role in water resource management and flood control in the area, regulated by the NYS DEC.

Despite its satisfactory condition assessment as of September 2018, Pompey Center Pond Dam has a moderate risk rating, prompting biennial inspections to ensure its structural integrity and safety. The dam features an uncontrolled spillway type with a width of 11 feet, capable of discharging up to 218 cubic feet per second. With a drainage area of 0.12 square miles, the dam serves as a vital infrastructure for the local community and wildlife, requiring ongoing risk management measures to mitigate potential hazards.

As a key component of the water resource infrastructure in the region, Pompey Center Pond Dam is a focal point for climate and water resource enthusiasts. With its strategic location and recreational significance, the dam serves as a testament to the symbiotic relationship between human development and environmental conservation efforts. Ongoing monitoring and maintenance ensure the dam's continued functionality and resilience in the face of changing climatic conditions and water management 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.
