Summary
Owned by the local government, this earth dam was completed in 1969 and designed by the USDA NRCS. With a height of 29 feet and a storage capacity of 787 acre-feet, this dam plays a crucial role in managing the flow of TR-Muddy Creek and Brusher Creek.
Regulated by the Mississippi Department of Environmental Quality, Muddy Creek Watershed Structure 26 Dam has a low hazard potential and is currently not rated for its condition assessment. Despite being uncontrolled, the spillway of the dam mitigates potential risks and ensures the safety of surrounding areas. With a moderate risk assessment, it is important for the local government to regularly inspect and maintain this structure to uphold its flood risk reduction purpose effectively.
As a part of the flood management infrastructure in the region, Muddy Creek Watershed Structure 26 Dam serves as a vital component in safeguarding the local community from potential flood hazards. With a focus on reducing risks and ensuring public safety, the dam's design and construction by the Natural Resources Conservation Service demonstrate a commitment to sustainable water resource management in 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.
