Summary
Owned by the local government and regulated by the Mississippi Department of Environmental Quality, this earth dam stands at a height of 22 feet and has a storage capacity of 545 acre-feet. The dam, designed by USDA NRCS, is classified as a buttress dam with a soil foundation, serving the TR- Muddy Cr; Hurricane Cr river or stream.
Despite being rated as low hazard potential and not currently assessed for its condition, the Muddy Creek Watershed Structure 13 Dam presents a moderate risk level (3) for potential emergencies. While it lacks a formal Emergency Action Plan (EAP) or updated contact information, the dam has not experienced any significant modifications since its construction. With uncontrolled spillways and outlet gates, this structure plays a vital role in managing floodwaters in the region and highlights the importance of ongoing monitoring and maintenance to ensure its effectiveness in mitigating risks and protecting the surrounding community and environment.

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.
