Summary

Standing at a height of 11 feet and stretching 435 feet in length, the dam holds a maximum storage capacity of 54 acre-feet and serves as a low hazard structure with a moderate risk assessment rating. The dam overlooks the TR-Bumps Creek and is regulated by the New York State Department of Environmental Conservation (NYS DEC), with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.

Despite being classified as a low hazard potential dam, Berry Hill Hunting Club Dam has a spillway width of 50 feet for uncontrolled discharge, capable of managing a maximum flow rate of 50 cubic feet per second. The dam's normal storage capacity is 31 acre-feet, covering a surface area of 7 acres within a small drainage area of 0.05 square miles. With its last inspection conducted in July 1998 and a condition assessment of "Not Rated," the dam remains operational for recreational activities while being monitored for any potential risks. As a significant feature in the region, the dam contributes to the water resource management and climate resilience efforts in Chenango County, New York.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
