South Fork No.27 dam
South Fork No.27
South Fork No.27 is a crucial flood risk reduction structure located in Pendleton, West Virginia. Built in 1960 by the USDA NRCS, this earth dam stands at a height of 71.2 feet and has a normal storage capacity of 39 acre-feet. With a hazard potential rated as high and a risk assessment of moderate (3), this dam is regulated by the West Virginia Department of Environmental Protection, ensuring regular inspections and enforcement of safety measures.
Managed by the local government, South Fork No.27 plays a vital role in protecting the surrounding area from potential flooding events along the South Fork river. The dam is equipped with uncontrolled spillways and outlet gates, serving as a critical infrastructure for flood control in the region. Despite its satisfactory condition assessment as of the last inspection in 2015, the dam's emergency action plan and risk management measures may need further evaluation and updates to meet current guidelines and ensure the safety of nearby residents.
As water resource and climate enthusiasts, understanding the significance of structures like South Fork No.27 is essential in safeguarding communities from the impacts of extreme weather events. By staying informed about the design, regulation, and maintenance of flood risk reduction dams, individuals can contribute to resilience-building efforts and promote sustainable water management practices in the face of evolving climate challenges.
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.27
Where does the data for South Fork No.27 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.
