Summary
Built in 1900, this earth dam stands at a height of 20 feet and stretches 220 feet in length, providing a storage capacity of 210 acre-feet. The dam sits on TR-Cherry Valley Creek and is regulated by the New York State Department of Environmental Conservation.
Despite its scenic surroundings and recreational value, Belvedere Lake Dam poses a significant hazard potential due to its poor condition assessment. The last inspection in 2018 revealed the dam's deteriorating state, prompting a moderate risk assessment rating. With a spillway width of 32 feet and a maximum discharge of 160 cubic feet per second, the dam's emergency action plan readiness and risk management measures need improvement to ensure public safety.
As water resource and climate enthusiasts monitor the status of Belvedere Lake Dam, concerns linger about its ability to withstand potential hazards and emergencies. With a risk assessment rating of moderate and a significant hazard potential, stakeholders must work towards enhancing the dam's condition assessment, emergency preparedness, and risk management measures to protect the surrounding community and preserve this vital water resource for future generations.

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.
