Summary
Completed in 1923, the dam stands at 18 feet high and spans 150 feet in length, with a storage capacity of 51 acre-feet and a maximum discharge rate of 1000 cfs. The dam, built as an earth structure on Spring Brook, serves a primary purpose other than flood control or water supply, making it a unique addition to the region's water management infrastructure.
With a low hazard potential and a moderate risk assessment rating, Palmyra Dam plays a crucial role in water resource management for the Wayne County area. Despite its age, the dam has not been rated for its condition assessment, but it is subject to regular inspections as mandated by the state regulatory agency. The dam features an uncontrolled spillway with a width of 42 feet, ensuring effective water release during high flow events. Although not owned or funded by federal agencies, the dam's operational and safety measures are overseen by state authorities to ensure its reliability and functionality in the face of changing climate conditions.
Water resource and climate enthusiasts can appreciate Palmyra Dam for its historical significance and continued importance in managing water resources in the region. As a privately owned structure with state regulatory oversight, the dam serves as a critical component in the local water infrastructure, providing flood protection and water storage capabilities for the surrounding community. With a focus on risk management and regular inspections, Palmyra Dam stands as a testament to sustainable water management practices in the face of evolving environmental challenges.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
