Summary
This earth-type dam stands at a height of 22 feet and spans 675 feet in length, with a storage capacity of 99 acre-feet and a surface area of 7 acres. It serves primarily for recreational purposes and is situated on the TR-MIDDLE BROOK river or stream.
Despite its significant hazard potential and poor condition assessment, Korianski Pond Dam is regulated by the New York State Department of Environmental Conservation (NYS DEC) and is subject to state permitting, inspection, and enforcement. The dam features an uncontrolled spillway with a width of 40 feet, and its last inspection was conducted in December 2019. With a moderate risk assessment rating of 3, the dam poses a potential risk that requires effective risk management measures to ensure public safety and environmental protection.
For water resource and climate enthusiasts, Korianski Pond Dam offers an intriguing case study of a privately owned dam in New York with unique design and operational characteristics. Its location, dimensions, and regulatory oversight present challenges and opportunities for sustainable water management and emergency preparedness efforts. As stakeholders continue to monitor and assess the dam's condition and risk profile, there is a need for collaboration and proactive measures to mitigate potential hazards and safeguard the surrounding community and ecosystem.

Dam Data Reference
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.
