Summary
Completed in 1961, this earth dam stands at a height of 16 feet and spans 510 feet in length, with a storage capacity of 63 acre-feet. Its primary purpose is for recreation, providing a serene escape for water resource and climate enthusiasts to enjoy the surrounding area.
Managed by the New York State Department of Environmental Conservation, Thomas J Kelaher Dam is state-regulated and inspected regularly to ensure its structural integrity. With a spillway width of 65 feet and a maximum discharge capacity of 455 cubic feet per second, the dam poses a significant hazard potential but is currently assessed to be in satisfactory condition, meeting safety guidelines and risk management measures.
Although the dam's emergency action plan is yet to be prepared, the risk assessment deems it to be of moderate risk. With its picturesque location along TR-MIDDLE BROOK and ample recreational opportunities, Thomas J Kelaher Dam is a captivating destination for water resource and climate enthusiasts to explore and appreciate the beauty of nature.

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.
