Summary

Completed in 1936, this concrete gravity dam stands at a height of 175 feet and has a maximum storage capacity of 228,045 acre-feet. The primary purpose of Wheeler Dam is hydroelectric power generation, with additional functions including navigation and recreation.

Managed by the Tennessee Valley Authority (TVA) and designed by both TVA and the Bureau of Reclamation, Wheeler Dam plays a crucial role in regulating water flow, providing flood control, and supporting various recreational activities in the area. With a spillway width of 176 feet and two locks each measuring 600 feet in length, the dam ensures controlled water release and navigation along the Tennessee River. However, due to its high hazard potential and very high risk assessment, proper risk management measures are essential to maintain the safety and integrity of the structure.

Despite not being regulated by the state, Wheeler Dam remains a significant landmark in Lauderdale County, Alabama, drawing the attention of water resource and climate enthusiasts alike. Its historical significance, engineering marvel, and contribution to the region's energy and water management make Wheeler Dam a fascinating site to explore for those interested in the intersection of water resources and climate dynamics.

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.
