Summary
Built in 1959 by the USDA NRCS, this earth dam stands at a height of 23 feet and serves primarily for flood risk reduction along the Horsepen Creek. With a storage capacity of 370 acre-feet, the dam covers a surface area of 13.12 acres, providing vital protection for the surrounding area.
Managed by the Mississippi Department of Environmental Quality, the Persimmon Creek Dam has a low hazard potential and is classified as having a moderate risk level. Despite its age, the dam's condition has not been formally rated, and there is no emergency action plan in place. With uncontrolled spillways and outlet gates, the structure's primary purpose remains flood risk reduction, ensuring the safety and security of the local community in Calhoun County.
Climate and water resource enthusiasts will be intrigued by the Persimmon Creek Structure Y-21-02 Dam's historical significance and its continued role in managing water flow and mitigating flood risks in the region. As a key part of the local infrastructure, this earth dam serves as a reminder of the importance of maintaining and monitoring our water resources to adapt to changing environmental conditions and ensure the safety of communities in the face of climate challenges.

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.
