Summary
Built in 1914, this concrete gravity dam stands at 23 feet tall and stretches 508 feet in length, providing a storage capacity of 1091 acre-feet. The dam's primary purpose is hydroelectric power generation, with a spillway width of 508 feet and significant hazard potential.
Managed by the Federal Energy Regulatory Commission, Taylorville - South Dam plays a crucial role in the region's water resource management and climate resilience efforts. With a drainage area of 251 square miles and a surface area of 170 acres, the dam helps regulate water flow and ensure the sustainable use of the Beaver River's resources. Despite its age, the dam remains in moderate risk condition, with regular inspections conducted by the regulatory agency to ensure public safety and environmental conservation.
As a key component of the New York District's infrastructure, Taylorville - South Dam contributes to the state's energy production and water supply resilience. With its multi-arch design and rock foundation, the dam exemplifies engineering excellence and innovation in the face of changing climate conditions. By harnessing the power of water for clean energy generation, this dam stands as a testament to the intersection of water resource management, climate adaptation, and sustainable development in the region.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
