Summary
Built in 1958 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the TR- Persimmon Creek. With a height of 23 feet and a storage capacity of 352 acre-feet, this buttress-type dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the Mississippi Department of Environmental Quality, Persimmon Creek Structure Y-21-51 Dam is regulated, inspected, and enforced to ensure its structural integrity and compliance with state standards. Despite its low hazard potential and moderate risk assessment, the dam has not been rated for its condition. With uncontrolled spillways and outlet gates, this dam remains a key component in managing water resources within the region. Although not under the jurisdiction of the US Army Corps of Engineers, this dam contributes significantly to flood control efforts in the area.
For water resource and climate enthusiasts, Persimmon Creek Structure Y-21-51 Dam presents a fascinating example of local government infrastructure designed to mitigate flood risks and protect the community. With its historical significance dating back to 1958, this earth dam continues to play a vital role in water management along Persimmon Creek. As efforts to assess and manage the dam's condition evolve, the importance of structures like Y-21-51 in safeguarding against potential flooding events becomes increasingly apparent in the face of changing climate patterns and water resource 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.
