Summary
Built in 1963 by USDA NRCS, this earth dam stands at a height of 19 feet and serves the primary purpose of flood risk reduction along the TR- Tackett Creek. With a storage capacity of 397 acre-feet, this dam plays a crucial role in managing water resources in the region.
The dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular state inspections and enforcement measures to ensure its safety and functionality. While it has a low hazard potential, the risk assessment indicates a moderate risk level (3). Despite not being rated for condition assessment, the dam continues to serve its purpose effectively in reducing the risk of flooding and protecting the surrounding areas from potential water-related disasters.
Located in Holmes County, Mississippi, the Tackett Watershed Structure 11 Dam contributes to the overall water management efforts in the region. With a focus on flood risk reduction, this dam plays a significant role in safeguarding the community and environment from the impacts of extreme weather events and ensuring the sustainable use of water resources. As a key piece of infrastructure, it highlights the importance of proactive water resource and climate management strategies for a resilient and secure future.

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.
