Jacks Branch Slurry Impoundment dam
Jacks Branch Slurry Impoundment
Jacks Branch Slurry Impoundment in Peytona, West Virginia, is a private tailings dam with a height of 365 feet and a storage capacity of 4690 acre-feet. Managed by the Mine Safety and Health Administration, this earth dam poses a high hazard potential due to its size and location. While not regulated by the state, this impoundment serves as a critical storage facility for tailings in the area.
Despite its high hazard potential, the condition assessment of Jacks Branch Slurry Impoundment is not available, raising concerns about its safety and stability. With no state jurisdiction or permitting requirements, the impoundment's risk management measures and emergency preparedness plans are also not documented. The dam, which was completed at an unknown date, lacks crucial information such as inspection frequency and last inspection date, leaving its structural integrity and potential environmental impact uncertain.
Water resource and climate enthusiasts interested in Jacks Branch Slurry Impoundment will find a complex and potentially risky structure that demands further attention and oversight. With its significant storage capacity and high hazard potential, this tailings dam in Boone County, West Virginia, raises important questions about safety, regulation, and emergency preparedness within the mining industry. As a privately owned facility with limited state involvement, the impoundment's condition and risk management practices warrant closer scrutiny to ensure the safety of surrounding communities and the environment.
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 Jacks Branch Slurry Impoundment
Where does the data for Jacks Branch Slurry Impoundment 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.
