Summary
Built in 1965 by the USDA NRCS, this earth dam stands at a height of 34 feet and serves as a key component for flood risk reduction along the TR-Black Creek Ditch. With a storage capacity of 269 acre-feet, the dam plays a crucial role in managing water resources and protecting the surrounding area from potential flooding events.
Managed by the local government and regulated by the Mississippi Department of Environmental Quality, Winstead Reservoir Dam has been deemed to have a low hazard potential with a moderate risk assessment. The dam features uncontrolled spillways and outlet gates, highlighting its focus on flood risk reduction as its primary purpose. Despite its age, the dam's condition assessment remains unrated, underscoring the need for ongoing monitoring and maintenance to ensure its continued effectiveness in safeguarding the community and environment.
As a notable structure within the Vicksburg District, Winstead Reservoir Dam stands as a testament to the collaboration between federal and state agencies in managing water resources and mitigating flood risks. With its historical significance and functional design, the dam continues to be a vital component in the region's water infrastructure, showcasing the importance of proactive measures in adapting to the challenges posed by climate change and ensuring the resilience of our water systems.

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.
