Summary
The dam serves multiple purposes, including providing a storage capacity of 71 acre-feet of water and a surface area of 23 acres. It is regulated by the New York State Department of Environmental Conservation (NYS DEC) and undergoes regular inspections, with a low hazard potential and a moderate risk assessment rating.
Despite not being rated for its condition, State Dam At Belmont has a spillway width of 463 feet and is equipped with uncontrolled spillways to manage potential overflow. The dam is owned and operated by the state, ensuring compliance with state regulations and permitting requirements. While it currently does not have an Emergency Action Plan (EAP) in place, its risk management measures are deemed adequate for its moderate risk level.
Water resource and climate enthusiasts would be intrigued by the historical significance and functional capabilities of State Dam At Belmont. With its strategic location along the Genesee River and its role in water storage and management, the dam presents a valuable asset in maintaining water resources and mitigating potential risks in the region. Its low hazard potential and moderate risk assessment indicate a well-maintained structure that continues to play a crucial role in water resource management in Allegany County, New York.

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.
