Summary

Designed by USDA NRCS and completed in 1968, this dam serves the primary purpose of flood risk reduction along Pond Brook. With a height of 23 feet and a length of 350 feet, the dam has a storage capacity of 1,010 acre-feet and a drainage area of 4.7 square miles.

Despite its significant hazard potential and poor condition assessment, the Genegantslet Creek Project Dam 2a has seen regular state inspections, permitting, and enforcement by the NYS DEC. The dam's spillway, with a width of 110 feet, is uncontrolled, allowing for a maximum discharge of 8,230 cubic feet per second. In addition to flood risk reduction, the dam also provides recreational opportunities for the local community, highlighting its multi-functional role in water resource management.

As a key infrastructure in the region, the Genegantslet Creek Project Dam 2a plays a crucial role in protecting the surrounding area from potential flooding events. With a moderate risk assessment rating, efforts to improve the dam's condition and emergency preparedness are essential to ensuring the safety and resilience of the community in the face of changing climate patterns and water resource 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.
