Summary
Built in 1962 by the USDA NRCS, this earth dam serves the primary purpose of flood risk reduction along the TR- Tippah Creek N Thompson Br. With a dam height of 28 feet and a storage capacity of 509 acre-feet, it plays a crucial role in managing water flow in the area.
This dam is regulated by the Mississippi Department of Environmental Quality and meets state inspection, enforcement, and permitting requirements. Despite its low hazard potential, the dam is classified as having a moderate risk level, with a rating of 3. While the condition of the dam is currently not rated, it remains an important structure for flood control in the region. With uncontrolled spillways and outlets, the North Tippah Watershed Structure Lt-6a-02 Dam is designed to mitigate flooding and protect surrounding communities from potential water-related disasters.
The Vicksburg District of the US Army Corps of Engineers oversees this dam, which has buttress core types and soil foundations. While there are no associated structures or locks, the dam plays a critical role in managing water flow and reducing flood risks in the area. With its strategic location and design, the North Tippah Watershed Structure Lt-6a-02 Dam remains an essential component of the region's water resource and climate management efforts.

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.
