Summary
Owned by the local government and designed by USDA NRCS, this earth dam stands at a height of 33 feet and stretches 472 feet in length. Completed in 1966, it serves the primary purpose of flood risk reduction for the surrounding area, with a normal storage capacity of 105 acre-feet and a maximum discharge of 371 cubic feet per second.
Situated on the UNT of Sand Creek, this dam plays a crucial role in managing water resources and protecting the local community from potential flooding events. Despite its poor condition assessment in 2015, the hazard potential is classified as low, with a moderate risk rating. The structure features an uncontrolled spillway and outlet gates, with a maximum storage capacity of 434 acre-feet. Regular state inspections and enforcement ensure the dam's compliance with regulatory standards, highlighting its importance in water resource management in the region.
With its historical significance and ongoing role in flood risk reduction, the Big Sand Watershed Structure Y-32-14 Dam stands as a testament to the collaborative efforts of local government agencies and the USDA NRCS. As climate change continues to impact water resources and extreme weather events, this earth dam serves as a critical piece of infrastructure that safeguards the community and surrounding areas from potential disasters. Its location in the Vicksburg District of Mississippi underscores its significance in regional water management and highlights the need for ongoing maintenance and monitoring to ensure its continued effectiveness in protecting the local environment and population.

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.
