Summary
Built in 1969 by the USDA NRCS, this earth dam stands at a height of 21 feet and serves the primary purpose of flood risk reduction along Pelucia Creek. With a storage capacity of 58 acre-feet, the dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding.
Managed by the Mississippi Department of Environmental Quality, this dam is state-regulated and undergoes regular inspections to ensure its structural integrity and operational effectiveness. With a low hazard potential and moderate risk assessment rating, the Pelucia Watershed Structure Y-33a-20 Dam is considered a reliable asset in the region's water resource management system. While not currently assessed for its condition, the dam's design and construction by the NRCS speak to its quality and durability in mitigating flood risks and safeguarding the local community from water-related emergencies.
As part of the Vicksburg District's jurisdiction, this dam is an essential component in the overall management of water resources in Carroll County, Mississippi. Its uncontrolled spillway and outlet gates provide essential mechanisms for water release and flow control during periods of high water levels. With a focus on flood risk reduction and a history of successful operation since its completion in 1969, the Pelucia Watershed Structure Y-33a-20 Dam stands as a testament to effective water resource management and climate resilience efforts 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.
