Summary
Built in 1948, this Earth-type dam stands at a hydraulic height of 16 feet and a structural height of 18 feet, with a length of 500 feet. It holds a maximum storage capacity of 64 acre-feet, with a normal storage of 60 acre-feet, making it a vital resource for the surrounding area.
Situated on the TR-Big Swamp Creek, Grant Dam is managed by the Mobile District of the US Army Corps of Engineers. Despite its low hazard potential, the dam's condition assessment is currently "Not Rated," with no recent inspection data available. While the dam has not been modified in recent years, it serves as a key component for both recreational activities and water supply in the region, highlighting the importance of maintaining and monitoring its structural integrity for the safety and well-being of the community.
With its historical significance dating back to the mid-20th century, Grant Dam plays a crucial role in managing water resources in Lowndes County, Alabama. As water resource and climate enthusiasts, understanding the infrastructure and functionality of such dams is essential in ensuring sustainable water management practices for future generations. Grant Dam stands as a testament to the importance of balancing human needs with environmental conservation, making it a noteworthy site for conservationists and engineers alike.

Dam Data Reference
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.
