Summary
Constructed in 1958 by the USDA NRCS, this earth dam stands at a height of 23 feet and has a storage capacity of 916 acre-feet. It serves the primary purpose of flood risk reduction along the TR-Persimmon Creek, within a drainage area of 1.96 square miles.
Managed by the Mississippi Department of Environmental Quality, this dam is state-regulated and inspected regularly to ensure its structural integrity. With a low hazard potential and a moderate risk assessment rating, this structure plays a crucial role in protecting the surrounding community from potential flooding events. While currently not rated for its condition assessment, the dam is considered to meet guidelines for emergency action plans and risk management measures.
Overall, Persimmon Creek Structure Y-21-07 Dam stands as a testament to the collaborative efforts of local government and federal agencies in safeguarding water resources and communities against the impacts of extreme weather events. Its strategic location, design, and operational protocols highlight the importance of infrastructure resilience in the face of climate change challenges. As a key asset in flood risk reduction, this dam serves as a critical component of water resource management in Calhoun, Mississippi, and underscores the importance of proactive disaster preparedness and mitigation strategies.

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.
