Summary
11e, is a vital structure owned by the local government in Jefferson Davis County, Mississippi. This earth dam, with a height of 43 feet and a length of 2050 feet, was completed in 1991 by the USDA NRCS to primarily mitigate flood risks along the Unt of White Sand Creek. The dam has a storage capacity of 1235 acre-feet, serving a drainage area of 2.09 square miles.
Managed by the Mississippi Department of Environmental Quality, this dam is regulated, inspected, and enforced to ensure its continued functionality. Despite its fair condition assessment and high hazard potential, the structure meets moderate risk assessment standards. With an uncontrolled spillway and outlet gates, the dam poses a significant risk in case of emergencies, highlighting the importance of regular inspections and risk management measures to safeguard the surrounding community and water resources.
White Sand - Greens Creek Str 11e Dam stands as a critical flood risk reduction asset in Mississippi, playing a crucial role in protecting the local area from potential inundation. Its design and construction by the Natural Resources Conservation Service emphasize the importance of sustainable water resource management and climate resilience in the face of increasing environmental challenges. As water resource and climate enthusiasts, understanding the significance of infrastructure like this dam is essential in promoting effective water management practices and ensuring the safety and sustainability of our communities.

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.
