Summary

Built in 1930, this earth dam stands at 100 feet in height and spans 1100 feet in length, with a storage capacity of 792,000 acre-feet. The dam serves multiple purposes, including flood risk reduction, hydroelectric power generation, navigation, recreation, and water supply for the region.

Managed by the Federal Energy Regulatory Commission, Conklingville has a controlled spillway with a width of 400 feet and three valve outlet gates. The dam's hazard potential is classified as high, with a very high risk assessment rating. Despite its age, the condition assessment of Conklingville is currently listed as not available, highlighting the need for continued monitoring and maintenance to ensure its safety and reliability for the surrounding communities and ecosystems.

For water resource and climate enthusiasts, Conklingville offers a fascinating example of how human infrastructure can harness the power of water for multiple beneficial uses. Its location in a picturesque setting in Hadley, New York, combined with its historical significance and ongoing importance in managing water resources and energy production, make it a site worth exploring and studying for those interested in the intersection of water management, climate resilience, and sustainable energy development.

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.
