Four Mile Branch Slurry Dam dam
Four Mile Branch Slurry Dam
Four Mile Branch Slurry Dam, located in Knott County, Kentucky, is a privately owned earth dam primarily used for tailings storage. Standing at a height of 350 feet and with a length of 1280 feet, this dam has a storage capacity of 8416 acre-feet. The dam is regulated by the Mine Safety and Health Administration, with inspections conducted by the same agency.
With a high hazard potential, Four Mile Branch Slurry Dam poses a significant risk in the event of a failure. Unfortunately, the condition assessment of the dam is not available, highlighting the importance of regular inspections and maintenance to ensure its structural integrity. Emergency action plans and risk management measures for the dam are also not specified, raising concerns about the preparedness and response in case of an emergency.
For water resource and climate enthusiasts, Four Mile Branch Slurry Dam serves as a point of interest due to its size and potential impact on the surrounding area in the event of a breach. Monitoring and assessing the condition of this dam are crucial in ensuring the safety of the community and the environment. As such, continued oversight and maintenance of this structure are essential to mitigate any potential risks associated with its operation.
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 Four Mile Branch Slurry Dam
Where does the data for Four Mile Branch Slurry Dam 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.
