Summary
Completed in 1971, this earth dam stands at a height of 33 feet and has a length of 575 feet, creating a reservoir with a storage capacity of 425 acre-feet. The primary purpose of the dam is for recreation, providing a surface area of 29 acres for activities like boating and fishing.
Despite being classified as having a low hazard potential, Ymca Pond Dam is situated on the TR-STILLWATER BROOK and is regulated by the New York State Department of Environmental Conservation. The dam has a spillway width of 50 feet and a maximum discharge capacity of 620 cubic feet per second. While its condition is currently not rated, the risk assessment for the dam is considered high, indicating a need for proper risk management measures to ensure its continued safety and functionality.
For water resource and climate enthusiasts, Ymca Pond Dam presents an intriguing case study of a privately owned recreational structure in upstate New York. With its modest size and high risk assessment, there is a potential for further exploration into the management practices and regulatory oversight of such dams in the region. The dam's history, design features, and current condition offer valuable insights into the intersection of water resource management, recreational infrastructure, and environmental conservation efforts in the area.

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.
