Nile Stone Slurry Impoundment dam
Nile Stone Slurry Impoundment
Nile Stone Slurry Impoundment, located in Thacker, West Virginia, is a privately owned earth dam structure built in 1993 with a primary purpose designated as 'Other'. This high hazard potential dam stands at a height of 272 feet, with a hydraulic height of 250 feet, and a length of 1440 feet. The impoundment has a storage capacity of 1705 acre-feet, with a surface area of 27 acres and a drainage area of 0.38 square miles.
Managed by the Mine Safety and Health Administration, Nile Stone Slurry Impoundment is regulated and inspected by the state agency, with enforcement and permitting also under state jurisdiction. While the condition assessment of the dam is currently not rated, it is crucial to note its high hazard potential and the need for regular inspections and maintenance to ensure safety. The impoundment is situated along the Conley Fork River and falls under the oversight of the Huntington District, with no associated locks or spillways.
Water resource and climate enthusiasts may find the Nile Stone Slurry Impoundment an intriguing case study for its unique design and purpose, as well as the challenges and responsibilities associated with managing a high hazard potential dam. The impoundment's location in Mingo County, West Virginia, adds to its significance in the region's water resource management landscape. With its notable height and storage capacity, it serves as a reminder of the importance of effective dam safety practices and the need for proactive measures to mitigate potential risks and ensure the security of surrounding communities and ecosystems.

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 Nile Stone Slurry Impoundment
Where does the data for Nile Stone 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.
