Summary
The dam, with a height of 22 feet and a length of 500 feet, serves as a flood risk reduction structure on TR-Mill Creek and Byers Creek. Designed by the USDA NRCS, the dam is primarily made of earth and has a buttress core type with a soil foundation.
The dam has a storage capacity of 244 acre-feet and an unsatisfactory condition assessment as of April 2016, with a low hazard potential. The structure is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections, with a moderate risk assessment rating of 3. While the dam has uncontrolled spillways and outlet gates, it meets state permitting and inspection requirements to ensure public safety and environmental protection.
Water resource and climate enthusiasts will be intrigued by the engineering details and regulatory oversight of the Mill Creek WS Str Lt-14b-1 Dam. Despite its moderate risk assessment, the dam plays a crucial role in managing flood risks in the Union County area. As a local government-owned structure, it highlights the importance of collaboration between state agencies and federal designers like the Natural Resources Conservation Service to safeguard communities and natural habitats from potential water-related disasters.

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.
