Leer Slurry Cell dam
Leer Slurry Cell
The Leer Slurry Cell is a crucial private-owned structure located in Grafton, West Virginia, designed for the primary purpose of tailings storage. With a towering dam height of 250 feet and a length of 4100 feet, this facility provides a massive storage capacity of 8540 acre-feet. Despite being classified as a high hazard potential structure, its condition assessment is currently unavailable, highlighting the importance of regular inspections and risk management measures.
Situated in Taylor County, the Leer Slurry Cell does not fall under state jurisdiction, permitting, inspection, or enforcement. Instead, it is regulated by the Mine Safety and Health Administration, emphasizing the significance of safety protocols in its operation. While the dam's construction year is unspecified, its sheer size and capacity make it a notable structure within the Huntington District of West Virginia.
The Leer Slurry Cell serves as a vital component in the region's water resource management, highlighting the intersection between industrial infrastructure and environmental conservation. As water resource and climate enthusiasts, understanding the intricacies of structures like the Leer Slurry Cell is essential for promoting sustainable practices and ensuring the safety of communities and ecosystems in the face of potential hazards.
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 Leer Slurry Cell
Where does the data for Leer Slurry Cell 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.
