Summary
This earth dam, completed in 1966, stands at a height of 38 feet and spans a length of 1220 feet, offering a storage capacity of 646 acre-feet. With a normal storage capacity of 38 acre-feet and a maximum discharge rate of 4025 cubic feet per second, this dam plays a vital role in mitigating flood risks in the area.
Managed by the local government and regulated by the New York State Department of Environmental Conservation, Ischua Creek Watershed Dam #3 is classified as having a significant hazard potential but is currently in satisfactory condition. Regular inspections occur every 4 years, with the last assessment completed in May 2018. The dam's emergency action plan is in place, and while the risk assessment is moderate, overall risk management measures and guidelines are yet to be detailed. Enthusiasts of water resources and climate will find this dam to be a key component in the region's flood protection infrastructure, safeguarding communities and enhancing resilience in the face of changing weather patterns and hydrological conditions.

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.
