Summary
Designed by the NRCS, this earth dam stands at 25 feet high and has a storage capacity of 113 acre-feet, serving primarily for flood risk reduction. With a low hazard potential and a moderate risk assessment, this dam plays a crucial role in mitigating potential flooding in the Yazoo County area.
Located in Yazoo, Mississippi, this dam is under the jurisdiction of the Vicksburg District of the USACE. With uncontrolled spillways and no associated locks, this structure is designed to efficiently manage water flow and reduce the risk of overflow during times of heavy rainfall. Despite not having a condition assessment rating, the Piney Creek Watershed Structure Y-38-23 Dam remains a key component of the region's water resource management strategy, ensuring the safety and security of the local community in the face of changing climate patterns.
As water resource and climate enthusiasts, it is important to recognize the significance of structures like the Piney Creek Watershed Structure Y-38-23 Dam in safeguarding against the impacts of extreme weather events. With its strategic design and purposeful construction, this dam serves as a valuable asset in the overall management of water resources in Mississippi, highlighting the importance of proactive measures in adapting to a changing climate and ensuring the resilience of our communities in the face of environmental 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.
