Summary
Constructed in 1964 by the USDA NRCS, this dam serves as a crucial flood risk reduction measure for the TR- Pelucia Creek. With a height of 38 feet and a storage capacity of 621 acre-feet, it plays a vital role in protecting the surrounding areas from potential flooding events.
Managed by the local government and regulated by the Mississippi Department of Environmental Quality, Pelucia Watershed Structure Y-33a-11 Dam is classified as having a low hazard potential and a moderate risk assessment rating. Despite its age, the dam's condition is currently not rated, highlighting the need for regular inspections and maintenance to ensure its continued effectiveness in flood control. With its uncontrolled spillway and outlet gates, this structure serves as a key component in the overall water resource management strategy for the region.
Enthusiasts of water resources and climate will appreciate the significance of Pelucia Watershed Structure Y-33a-11 Dam in safeguarding the community from potential flood risks. As a vital piece of infrastructure in the Vicksburg District, this earth dam continues to play a crucial role in managing water flow and protecting the local environment. With its historical significance and ongoing importance, this dam serves as a reminder of the essential role that dams play in maintaining water security and mitigating the impacts of extreme weather events.

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.
