Summary

Built in 1912, this concrete dam stands at a height of 68 feet and stretches 546 feet in length, harnessing the power of the Seneca River/Canal for hydroelectricity generation and navigation purposes. Managed by the State, this dam is not regulated by the state but is subject to inspections by the Federal Energy Regulatory Commission.

With a storage capacity of 2700 acre-feet and a maximum discharge of 8360 cubic feet per second, Seneca Falls Dam plays a crucial role in water resource management in the region. Its uncontrolled spillway and array of outlet gates, including slide gates, ensure effective flood control and water flow regulation. Despite being classified as having a high hazard potential, this dam has a moderate risk assessment rating, highlighting the importance of ongoing risk management measures.

Seneca Falls Dam stands as a historic landmark, blending functionality with engineering excellence. Its role in harnessing renewable energy and facilitating navigation underscores its significance in the region's water resource infrastructure. As climate enthusiasts and water resource advocates, the intricate details and operational insights of Seneca Falls Dam offer a fascinating glimpse into the intersection of human ingenuity and environmental stewardship.

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.
