Summary
Built in 1960 by the USDA NRCS, this earth dam stands at a height of 75.6 feet and has a hydraulic height of 62.6 feet, providing essential protection to the surrounding area. With a storage capacity of 774 acre-feet and a normal storage of 62 acre-feet, this dam plays a crucial role in managing water flow and mitigating potential flood hazards in the region.
Despite its age, South Fork No.10 is deemed to be in fair condition, with a high hazard potential and moderate risk assessment rating. The dam is under the jurisdiction of the West Virginia Department of Environmental Protection and is subject to regular inspections and enforcement measures to ensure its continued safety and effectiveness. While the dam currently has uncontrolled spillways and outlet gates, it remains a key component in the flood risk reduction efforts in Pendleton County, contributing to the overall resilience of the local water resource management infrastructure.
As a part of the broader flood risk reduction strategy in the area, South Fork No.10 serves as a critical piece of infrastructure designed to protect the community from potential inundation and water-related emergencies. Its presence highlights the importance of proactive management and maintenance of water resources in the face of changing climate patterns and increasing water-related risks. For water resource and climate enthusiasts, understanding the role and condition of structures like South Fork No.10 is essential in ensuring the continued safety and sustainability of the region's water management systems.

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.
