Summary
Built in 1974 by the USDA NRCS, this earth dam stands at a height of 74 feet and spans 1800 feet in length. It serves the primary purpose of flood risk reduction, with a storage capacity of 3598 acre-feet and a drainage area of 9.6 square miles along the Batavia Kill.
Managed by the NYS DEC, this dam is state-regulated, permitted, inspected, and enforced to ensure its structural integrity and functionality. With a high hazard potential and a satisfactory condition assessment, the dam poses a moderate risk level according to the latest evaluation. Its spillway type is uncontrolled, with a width of 414 feet, capable of handling a maximum discharge of 45,900 cubic feet per second. The dam also offers recreational opportunities and covers a surface area of 26 acres.
In the event of an emergency, the dam's Emergency Action Plan (EAP) is regularly updated and meets guidelines for risk management. With regular inspections and maintenance, Batavia Kill Watershed Dam #1 plays a critical role in protecting the surrounding communities from potential flooding while offering a recreational oasis for water resource and climate enthusiasts to enjoy.

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.
