Summary
Built in 1960 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along Pelucia Creek in Carroll County. Standing at a height of 30 feet with a storage capacity of 416 acre-feet, this structure plays a crucial role in mitigating potential flooding events in the region.
Managed by the Mississippi Department of Environmental Quality, Pelucia Watershed Structure Y-33a-13 Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its structural integrity and functionality. While categorized as having a low hazard potential, the dam is considered to have a moderate risk level, indicating the need for ongoing risk management measures. Despite not being rated for its condition, the dam remains a key component in the water resource management system of the area, providing vital flood protection to the surrounding community.
With its uncontrolled spillway and outlet gates, Pelucia Watershed Structure Y-33a-13 Dam is designed to handle floodwaters and protect downstream areas from potential inundation. While not under the jurisdiction of the USACE, this structure stands as a testament to the collaborative efforts between local government agencies and federal entities in safeguarding water resources and addressing climate-related challenges in the region.

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.
