Summary
With a dam height of 23.5 feet and a storage capacity of 6600 acre-feet, this facility plays a crucial role in water resource management in the region. Despite being regulated by the Federal Energy Regulatory Commission, Pepperell Paper has a low hazard potential and a moderate risk assessment rating.
The facility's uncontrolled spillway, 251-foot dam length, and 294-acre surface area make it a significant feature in the area's hydrology. The dam's normal storage capacity of 4530 acre-feet ensures a steady supply of water for both power generation and environmental purposes. While the condition assessment of Pepperell Paper is currently not available, it remains an essential asset for both water resource management and climate enthusiasts interested in sustainable energy solutions.
With its historical significance and ongoing role in water resource management, Pepperell Paper stands as a testament to the intersection of hydroelectric power and environmental conservation. As a key player in the region's energy landscape, this facility continues to be a point of interest for those passionate about water resources and climate resilience. Despite its low hazard potential, Pepperell Paper's risk assessment highlights the importance of ongoing monitoring and management to ensure its continued operation and contribution to the local ecosystem.

Dam Data Reference
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.
