Summary
Designed by NRCS, this earth dam with a buttress core stands at a height of 25 feet, providing flood risk reduction along the UNT of Duncan Branch. With a storage capacity of 243 acre-feet and a surface area of 7 acres, this dam plays a crucial role in mitigating the impact of heavy rainfall and potential flooding in the area.
Managed by the MS Department of Environmental Quality, the dam is regulated, permitted, inspected, and enforced to ensure its structural integrity and functionality. Despite its low hazard potential, the dam is assessed as not rated in terms of condition, highlighting the need for ongoing monitoring and evaluation. The risk assessment for this dam is moderate, indicating a level 3 risk, which underscores the importance of continued risk management measures to safeguard the surrounding community and environment.
As part of the Vicksburg District, the Upper Tippah Watershed Structure Lt-6-05 Dam serves as a vital component in the region's water resource and climate resilience efforts. With its primary purpose being flood risk reduction, this dam stands as a testament to collaborative federal and state efforts in safeguarding communities against potential water-related disasters. By adhering to regulatory guidelines and implementing risk management measures, this dam plays a crucial role in maintaining the safety and well-being of the area's residents and ecosystems.

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.
