Summary
Completed in 1995, this earth dam stands at a height of 37 feet and serves the primary purpose of flood risk reduction along Hurricane Creek. With a maximum storage capacity of 10,857 acre-feet and a normal storage capacity of 1,830 acre-feet, the dam covers a surface area of 354 acres and has a drainage area of 26.47 square miles.
Managed by the Mississippi Department of Environmental Quality, the Tuscumbia Watershed Structure 8a Dam is classified as low hazard potential with a moderate risk rating. The dam features an uncontrolled spillway type and outlet gates, with a maximum discharge capacity of 5,293 cubic feet per second. While the condition assessment is not rated, the dam has not been inspected recently, and emergency action plans and inundation maps have not been prepared as of the last data update in May 2021.
Overall, the Tuscumbia Watershed Structure 8a Dam plays a crucial role in mitigating flood risks in the area and protecting the surrounding communities from potential water-related hazards. Its strategic location and design contribute to the overall water resource management efforts in the region, highlighting the importance of maintaining and monitoring such critical infrastructure for the long-term sustainability of the watershed and climate resilience.

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.
