Summary
Owned by the local government, this structure was designed by the USDA NRCS and completed in 1967 for the primary purpose of flood risk reduction along the Whitehead Creek. With a height of 26 feet and a storage capacity of 407 acre-feet, this dam plays a crucial role in managing water resources in the area.
Managed by the Mississippi Department of Environmental Quality, the Big Sand Watershed Structure Y-32-22 Dam is regulated, permitted, inspected, and enforced to ensure its safety and functionality. With a low hazard potential and a moderate risk assessment rating, this dam provides vital protection against flooding while also serving as a valuable resource for the local community. Despite not being rated for its condition, this structure continues to play a key role in water management and climate resilience efforts in the region.
As part of the flood risk reduction strategy, the Big Sand Watershed Structure Y-32-22 Dam features an uncontrolled spillway and outlet gates. Its location on the Whitehead Creek, within the Mobile District of the USACE, highlights the collaboration between different agencies to ensure the safety and efficiency of water infrastructure in the area. Overall, this dam stands as a testament to the importance of sustainable water resource management and climate adaptation measures in safeguarding communities against natural disasters.

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.
