Logan Martin dam
Logan Martin
Logan Martin is a captivating hydroelectric dam located in St. Clair, Alabama, along the Coosa River. Owned by a public utility, this gravity dam stands at an impressive height of 97 feet, with a structural height of 142 feet and a length of 6076 feet. Completed in 1964, Logan Martin boasts a storage capacity of 650,000 acre-feet, making it a crucial resource for flood risk reduction, hydroelectric power generation, recreation, and water supply for the region.
Managed by the Federal Energy Regulatory Commission, Logan Martin is equipped with a controlled spillway and seven Tainter radial gates for efficient water release. With a high hazard potential due to its size and location, the dam poses a significant risk that is closely monitored through regular inspections and emergency action planning. Despite its age, Logan Martin continues to operate effectively, providing ample storage space, a maximum discharge capacity of 167,000 cubic feet per second, and a surface area of 15,263 acres for various water resource management purposes.
For water resource and climate enthusiasts, Logan Martin represents a fascinating engineering feat that balances the needs of flood control, power generation, and recreational activities. With its strategic location on the Coosa River, this dam plays a vital role in water management for the region, showcasing the importance of sustainable infrastructure for addressing the challenges of a changing climate. As a key player in the Federal energy regulatory landscape, Logan Martin exemplifies the critical role of dams in ensuring water security and environmental resilience in the face of evolving weather patterns and increasing water demands.

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 Logan Martin
Where does the data for Logan Martin 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.
