Tuscumbia Watershed Structure 8a Dam dam
Tuscumbia Watershed Structure 8a Dam
Tuscumbia Watershed Structure 8a Dam, also known as Dam 8a, is a locally owned structure in Corinth, Mississippi, designed by the USDA NRCS. 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
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Tuscumbia Watershed Structure 8a Dam
Where does the data for Tuscumbia Watershed Structure 8a Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
