Summary
Constructed in 1976 by the USDA NRCS, this earth dam serves the primary purpose of flood risk reduction along the TR- Muddy Creek. With a height of 31 feet and a storage capacity of 88 acre-feet, the dam plays a crucial role in mitigating the potential impact of flooding in the area.
Managed by the Mississippi Department of Environmental Quality, the Muddy Creek Watershed Structure 28 Dam is regulated, permitted, inspected, and enforced by the state agency to ensure its safety and compliance with regulations. Despite being classified as having a low hazard potential and a moderate risk assessment, the dam's condition has not been rated. While it currently operates with uncontrolled spillways and outlet gates, there have been no associated structures or modifications reported over the years.
For water resource and climate enthusiasts, the Muddy Creek Watershed Structure 28 Dam offers an intriguing case study in local government dam management and flood risk reduction efforts. With its earth dam structure and buttress core type, the dam stands as a testament to the importance of proactive infrastructure measures in safeguarding communities from the impacts of natural disasters like flooding. As efforts continue to monitor and maintain the dam's integrity, its role in protecting the surrounding area from potential inundation remains a critical aspect of water resource management in Tippah County, 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.
