Summary
Built in 1956 by the USDA NRCS, this Earth dam stands at a height of 18 feet and has a storage capacity of 428 acre-feet. The dam is designed to mitigate flood risks along the TR- Brushy Creek, contributing to the overall water resource management in the region.
Managed by the local government and regulated by the Mississippi Department of Environmental Quality, Persimmon Creek Structure Y-21-05 Dam plays a crucial role in maintaining the safety and integrity of the surrounding area. With a low hazard potential and a moderate risk assessment rating, the dam is considered a reliable asset for flood control. While not currently rated for condition assessment, the dam remains operational and serves its primary purpose effectively.
For water resource and climate enthusiasts, Persimmon Creek Structure Y-21-05 Dam offers a glimpse into the intersection of infrastructure, environmental regulations, and risk management. As a key component of the Vicksburg District's flood risk reduction strategy, this dam showcases the importance of sound engineering practices and regulatory oversight in ensuring the resilience of water systems 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.
