Summary
This earth-type dam, designed by the USDA NRCS and completed in 1968, serves the primary purpose of flood risk reduction along the TR- Muddy Creek. With a height of 29 feet and a storage capacity of 387 acre-feet, this dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding events.
Managed and regulated by the Mississippi Department of Environmental Quality, Muddy Creek WS Str 9 Dam has a low hazard potential and is currently in satisfactory condition as per the last assessment in 2010. While the dam has uncontrolled spillways and outlets, it has a moderate risk level (3) and meets the necessary guidelines for risk management. Despite not having associated structures or locks, the dam stands as a testament to effective flood risk reduction measures and the collaborative efforts of various agencies in safeguarding water resources and communities in Tippah County.
For water resource and climate enthusiasts, Muddy Creek WS Str 9 Dam serves as a notable example of infrastructure dedicated to managing flood risks and ensuring water security in the region. With its strategic location and design elements, this dam showcases the importance of proactive measures in mitigating potential hazards and safeguarding the environment. As climate change continues to impact water systems, structures like Muddy Creek WS Str 9 Dam play a crucial role in enhancing resilience and protecting communities from the adverse effects of extreme weather events.

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.
