Flat Top Mine-#1 Impoundment dam
Flat Top Mine-#1 Impoundment
The Flat Top Mine-#1 Impoundment, located in Jefferson County, Alabama, is a rockfill dam with a hydraulic height of 70 feet and a structural height of 75 feet. Completed in 1979, this dam serves a primary purpose of "Other" and has a storage capacity of 35 acre-feet. While the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, it has not been inspected in recent years.
Situated along the TR-LOCUST FORK river/stream, the Flat Top Mine-#1 Impoundment is owned by a private entity and is not regulated or permitted by the state. Despite its critical role in water resource management and climate control, this dam has not undergone recent inspection or maintenance, raising concerns about its long-term stability and safety. With a maximum discharge of 115 cfs, this dam plays a crucial role in flood control and water storage in the region.
As water resource and climate enthusiasts monitor the status of dams like the Flat Top Mine-#1 Impoundment, it is important to advocate for regular inspections and maintenance to ensure their continued functionality and safety. With its location in a high-risk area prone to flooding, proper monitoring and management of this dam are essential to prevent potential disasters and protect the surrounding communities and ecosystems.
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 Flat Top Mine-#1 Impoundment
Where does the data for Flat Top Mine-#1 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 Low 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.
