Summary

Built in 1973 by the USDA NRCS, this earth-type dam stands at a height of 57 feet and spans 1050 feet across the Little Choconut Creek. With a maximum storage capacity of 1480 acre-feet, the dam serves as a crucial defense against high-risk flooding events in the area.

Managed by the local government and regulated by the NYS DEC, Finch Hollow Site 2 Dam is subject to regular inspection and enforcement to ensure its structural integrity and safety. Classified as having a high hazard potential, the dam has a moderate risk assessment rating and is equipped with an uncontrolled spillway with a width of 107 feet. Despite its critical role in flood risk reduction, the dam's condition assessment is currently listed as "Not Rated."

Enthusiasts of water resources and climate resilience will find Finch Hollow Site 2 Dam to be a fascinating example of engineering ingenuity and environmental protection. As a key component in safeguarding the surrounding community from the threat of flooding, this dam's strategic design and operational protocols highlight the importance of proactive risk management in the face of ever-changing weather patterns and hydrological challenges.

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.
