Summary
Constructed in 1962 by the USDA NRCS, this earth dam stands at a height of 26 feet and has a storage capacity of 787 acre-feet. The dam is regulated by the Mississippi Department of Environmental Quality and is designed to protect the surrounding area from the potential hazards of high water levels.
Despite its important role in flood risk reduction, the Upper Tippah Watershed Structure Lt-6-17 Dam is currently rated as having a high hazard potential and an unsatisfactory condition assessment. The last inspection conducted in November 2017 revealed its critical state, highlighting the need for immediate attention and maintenance. With a moderate risk assessment score of 3, it is evident that proactive risk management measures are required to ensure the continued effectiveness and safety of this essential infrastructure.
As water resource and climate enthusiasts, it is crucial to recognize the significance of structures like the Upper Tippah Watershed Structure Lt-6-17 Dam in safeguarding communities and ecosystems from the impacts of flooding. By staying informed about its condition, advocating for necessary upgrades and maintenance, and supporting responsible management practices, we can contribute to the resilience and sustainability of our water resources in the face of changing environmental conditions.

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.
