Summary
This earth dam with a buttress core stands at a height of 20 feet and has a storage capacity of 370 acre-feet. The dam is situated on Persimmon Creek in Calhoun County, Mississippi, and is regulated by the Mississippi Department of Environmental Quality.
Despite being classified as having a low hazard potential, the dam is rated as having a moderate risk level. While the condition assessment is marked as "Not Rated," the dam is reported to be in operational condition with no associated structures. The inspection frequency, emergency action plan status, and risk management measures for the dam are currently not available. With its uncontrolled spillway and outlet gates, the Persimmon Creek Structure Y-21-08 Dam remains a vital piece of infrastructure for flood risk management in the area.
For water resource and climate enthusiasts, the Persimmon Creek Structure Y-21-08 Dam offers a fascinating study in the design and management of earth dams for flood control. With its historical significance and continued relevance in mitigating flood risks in the region, this dam serves as a reminder of the ongoing efforts to balance water resource management and environmental protection. Monitoring and maintaining the integrity of structures like the Persimmon Creek Dam are crucial in ensuring the safety and sustainability of water resources in Mississippi and beyond.

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.
