South Fork No. 9 dam
South Fork No. 9
South Fork No. 9 is a significant earth dam located in Fort Seybert, West Virginia, along the Dice Run river. Built in 1963 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction in the area. Standing at a height of 99.2 feet with a hydraulic height of 85.2 feet, it has a storage capacity of 949 acre-feet and a normal storage level of 54 acre-feet.
Managed by the Natural Resources Conservation Service, South Fork No. 9 has a fair condition assessment as of the last inspection in April 2015. With a high hazard potential and a moderate risk assessment, this dam falls under state jurisdiction and is regulated by the West Virginia Department of Environmental Protection's Division of Water and Waste Management (DWWM). Despite its age, the dam continues to serve its purpose effectively, showcasing the importance of proper maintenance and inspection protocols for water resource and climate enthusiasts.
In times of emergency, the dam's uncontrolled spillway and outlet gates play a crucial role in managing water levels and mitigating risks to downstream areas. With a history of periodic inspections and a designated emergency action plan, South Fork No. 9 remains a key infrastructure for flood control in Pendleton, West Virginia. As climate change continues to impact water resources, the maintenance and upkeep of such dams become increasingly vital for the safety and well-being of local communities.
Dam data reference
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.
- 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.
- 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.
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, environmental 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.

About South Fork No. 9
Where does the data for South Fork No. 9 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
