Summary
Completed in 1937, this hydroelectric structure stands at a height of 27 feet and spans a length of 328 feet, with a storage capacity of 800 acre-feet. The dam's primary purpose is hydroelectric power generation, with an uncontrolled spillway width of 244 feet and a maximum discharge capacity of 9700 cubic feet per second.
Managed by the Federal Energy Regulatory Commission, Upper Beaver Falls poses a high hazard potential due to its proximity to populated areas and downstream infrastructure. While the dam's condition assessment is currently not available, regular inspections are conducted to ensure its safety and compliance with regulatory standards. The dam's risk assessment is categorized as moderate, signaling a need for ongoing monitoring and risk management measures to mitigate potential hazards and safeguard the surrounding environment and communities.
Water resource and climate enthusiasts will find Upper Beaver Falls a fascinating example of early 20th-century hydroelectric infrastructure, blending engineering prowess with environmental stewardship. The dam's presence on the Beaver River contributes to the region's energy production while highlighting the importance of responsible dam management and maintenance in mitigating risks and ensuring long-term sustainability. As technology and regulations evolve, the continued monitoring and upkeep of Upper Beaver Falls serve as a crucial aspect of preserving both water resources and the surrounding ecosystem for future generations.

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.
