Summary
The dam is an earth structure with a height of 15 feet and a length of 390 feet, creating a reservoir with a storage capacity of 68 acre-feet. The dam is regulated by the Mississippi Department of Environmental Quality and undergoes state inspection, permitting, and enforcement to ensure its safety and compliance with regulations.
Despite being classified with an undetermined hazard potential and a moderate risk assessment, Holcomb Dam has not been rated for its condition assessment. The dam features an uncontrolled spillway and a drainage area of 0.13 square miles, with a maximum discharge capacity of 119 cubic feet per second. Although the dam has not been modified in recent years, it is important for water resource and climate enthusiasts to monitor its condition and management to prevent any potential risks or hazards associated with its operation. With its recreational focus and its location in the Mobile District of the US Army Corps of Engineers, Holcomb Dam provides an intriguing site for those interested in water resource management and dam infrastructure.

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.
