Maynard Branch Slurry Impoundment dam
Maynard Branch Slurry Impoundment
Maynard Branch Slurry Impoundment is a private structure located in East Lynn, West Virginia, with a primary purpose of storing tailings. This earth dam stands at a height of 262 feet and has a storage capacity of 12,630 acre-feet. While not state-regulated, it falls under the jurisdiction of the Mine Safety and Health Administration for inspection and enforcement. The impoundment is considered to have a high hazard potential, although detailed condition assessments are not currently available.
Despite lacking recent inspection data and comprehensive risk assessments, the Maynard Branch Slurry Impoundment presents an intriguing case study for water resource and climate enthusiasts. The dam's significant height and storage capacity may raise concerns about safety and environmental impact, particularly given its location in Wayne County. As this structure remains unregulated by the state, there is an opportunity for further research and analysis to better understand the potential risks and management measures associated with this impoundment.
For those interested in the intersection of water resources, climate, and industrial infrastructure, the Maynard Branch Slurry Impoundment offers a compelling subject for investigation. With its high hazard potential and private ownership, this structure poses questions about regulatory oversight, emergency preparedness, and environmental stewardship. By delving into the details of this earth dam and its operational history, enthusiasts can gain valuable insights into the complexities of managing water resources in a changing climate.

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 Maynard Branch Slurry Impoundment
Where does the data for Maynard 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.
