Summary
Built in 1991 by the USDA NRCS, this earth dam stands at a height of 45 feet and spans 692 feet in length. It plays a crucial role in mitigating flood risks along the White Sand Creek, with a storage capacity of 222 acre-feet and a normal storage of 63 acre-feet.
Managed by the Mississippi Department of Environmental Quality, this dam is state-regulated and subject to regular inspections to ensure its structural integrity. Despite being classified as having a low hazard potential, the dam is deemed to be in satisfactory condition as of the last assessment in 2015. With a moderate risk assessment rating, the dam serves as a vital piece of infrastructure in the region, protecting surrounding communities from potential flooding events.
As part of the Vicksburg District, this dam is a testament to the collaborative efforts between local government agencies and federal partners in safeguarding water resources and managing climate-related risks. Its design and construction highlight the importance of proactive flood risk reduction measures in ensuring the resilience of communities in the face of changing environmental conditions.

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.
