Summary

Completed in 1984, this concrete gravity dam boasts a height of 7 feet and a length of 140 feet, providing a storage capacity of 75 acre-feet. With a maximum discharge of 9300 cubic feet per second and a low hazard potential, Wadhams contributes to the local ecosystem while minimizing environmental risks.

Managed by the Federal Energy Regulatory Commission and regulated by the New York State Department of Environmental Conservation, Wadhams operates under strict inspection and enforcement protocols to ensure its structural integrity and safety. Despite its moderate risk assessment rating, the dam's emergency action plan is up to date, with a frequency of inspections every three years. With a primary purpose of hydroelectric generation and secondary functions including fire protection and fish pond maintenance, Wadhams exemplifies the multifaceted benefits of sustainable water resource management in the face of climate change challenges.

As climate enthusiasts and water resource advocates, the intricate details of Wadhams' construction and operation serve as a reminder of the delicate balance between human development and environmental preservation. With a focus on innovation and sustainability, dams like Wadhams play a crucial role in meeting energy demands while protecting the surrounding ecosystems and communities. By staying informed and engaged in the regulation and maintenance of such vital infrastructure, we can ensure a resilient and sustainable future for generations to come.

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.
