Summary
Completed in 2002, this earth dam stands at a height of 17.8 feet and has a length of 800 feet. It has a maximum storage capacity of 163 acre-feet and a normal storage of 81 acre-feet, serving as a crucial water resource for the surrounding area with a surface area of 12.7 acres and a drainage area of 0.56 square miles.
Managed by the Mississippi Department of Environmental Quality, the dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and functionality. With a low hazard potential and a moderate risk assessment rating, Tom Allen Dam plays a vital role in mitigating flooding and providing recreational opportunities for the community. Despite not being rated for its condition, the dam continues to serve its purpose effectively and contributes to the overall water resource management in the region.
Situated on the UNT of Clear Creek and falling under the jurisdiction of the Vicksburg District, Tom Allen Dam is a valuable asset for water resource and climate enthusiasts. Its uncontrolled spillway and buttress core type make it a unique structure, offering both safety and recreational benefits to the local area. With its strategic location and storage capacity, the dam serves as a key component in water management efforts, highlighting the importance of sustainable and well-regulated infrastructure in ensuring the resilience of our water resources in the face of changing climate conditions.

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.
