Summary

These earth dams were completed in 1960 and primarily serve the purpose of recreation. The dams have a height of 12 feet and a length of 2220 feet, providing a storage capacity of 125 acre-feet with a normal storage level of 105 acre-feet.

The dams are regulated by the New York State Department of Environmental Conservation (NYS DEC) and have a low hazard potential rating. The spillway type is uncontrolled with a width of 23 feet, and the maximum discharge capacity is 46 cubic feet per second. The drainage area for the dams is 0.05 square miles, with a surface area of 21 acres. The last inspection of the dams was conducted in July 1998, with a risk assessment rating of moderate (3).

Overall, Chenango County Pond Dams A & B are essential infrastructure for recreational purposes in the area, providing water storage and flood control benefits. With proper regulation and maintenance, these dams continue to serve their intended purpose while ensuring public safety and environmental sustainability in the region.

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.
