Summary
Built in 1938, this gravity dam serves primarily for recreational purposes with a height of 20 feet and a length of 150 feet. It has a storage capacity of 100 acre-feet and a maximum discharge of 450 cubic feet per second.
Managed by the Mobile District of the US Army Corps of Engineers, Gray has been deemed to have a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite not being regulated by the state, the dam has not undergone any recent inspections or maintenance activities. While it meets recreational needs, the lack of updated emergency action plans and risk assessments may pose potential safety concerns for the surrounding area.
With its picturesque location in a Congressional District of Alabama, Gray serves as a valuable resource for water recreation enthusiasts. However, there is a need for increased oversight and maintenance to ensure the safety and continued functionality of the dam in the face of changing climate conditions and potential risks.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
