Summary
Built in 1965 by the USDA NRCS, this earth dam stands at a height of 33 feet and has a storage capacity of 734 acre-feet. Situated on the TR- SAND CREEK, this dam plays a vital role in managing water flow and reducing the risk of flooding in the area.
Owned by the local government and regulated by the Mississippi Department of Environmental Quality, Big Sand Watershed Structure Y-32-07 Dam has been deemed to have a high hazard potential with a satisfactory condition assessment. While the dam has uncontrolled spillways and outlet gates, its risk assessment is moderate. The inspection frequency and emergency preparedness measures for the dam are not specified, but the last inspection in September 2015 confirmed its satisfactory condition.
With its strategic location and significant impact on flood risk reduction in the region, Big Sand Watershed Structure Y-32-07 Dam serves as a critical infrastructure managed by the local government and designed by the USDA NRCS. As climate change continues to pose challenges to water resources management, structures like this play a vital role in protecting communities and ensuring the sustainable use of water in Mississippi.

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.
