Summary
The earth dam stands at a height of 19 feet and has a length of 950 feet, with a storage capacity of 86 acre-feet. With a normal storage capacity of 58 acre-feet and a maximum discharge of 71 cubic feet per second, the dam serves as a vital resource for water management in the area.
Managed by a private owner, Hayes Dam is regulated by the New York State Department of Environmental Conservation (NYS DEC) and undergoes regular inspections and enforcement to ensure its safety and compliance with state regulations. Despite being classified as low hazard potential, the dam has a moderate risk level (3) based on its risk assessment, indicating the need for ongoing risk management measures.
Water resource and climate enthusiasts visiting Hayes Dam can appreciate its contribution to the local ecosystem and recreational opportunities. The dam's location on the TR-Pleasant Brook river provides a serene setting for outdoor activities, while its modest size and controlled spillway width of 30 feet ensure minimal risk to surrounding areas. As a key feature in the Baltimore District, Hayes Dam continues to play a crucial role in water resource management and environmental conservation efforts in the region.

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.
