Summary

Managed by a public utility, this gravity dam stands at an impressive height of 168 feet and has been providing flood risk reduction, hydroelectric power, recreation, and water supply since its completion in 1926. With a storage capacity of 1,622,000 acre-feet and a surface area of 40,000 acres, this reservoir on the Tallapoosa River offers both scenic beauty and crucial water resource management.

The dam's controlled spillway, with a width of 720 feet, ensures the safe release of water during periods of high flow, while its 20 slide gates provide operational versatility. Despite its high hazard potential, the dam's risk assessment remains at a very high level, underscoring the importance of proactive risk management measures. From its rock foundation to its multi-arch core design, Martin Dam exemplifies the harmonious integration of engineering excellence with environmental stewardship, making it a key player in Alabama's water resource and climate resilience efforts.

With Martha Roby (R) representing the district in Congress, the Federal Energy Regulatory Commission oversees the dam's regulatory and inspection processes. As an essential component of the Mobile District, Martin Dam not only generates clean hydroelectric power but also serves as a recreational hub for locals and tourists alike. From its historic significance to its ongoing commitment to safety and sustainability, Martin Dam stands as a beacon of innovation and collaboration in the realm of water resource management and climate resilience.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
