Summary
Built in 1979 by the USDA NRCS, this earth-type dam stands at a height of 34 feet and serves the primary purpose of flood risk reduction in the area. It is owned and regulated by the local government, with the Mississippi Department of Environmental Quality overseeing its operation, inspection, and enforcement.
With a storage capacity of 329 acre-feet, the Lower Tallahatch Y-10-34 Dam plays a crucial role in managing water resources and mitigating flood risks in the region. The dam is classified as having a low hazard potential and a moderate risk assessment rating, indicating the importance of regular monitoring and maintenance to ensure its structural integrity and functionality. Despite not being rated for condition assessment, the dam continues to fulfill its purpose effectively and contributes to the overall water resource management efforts in Panola County, Mississippi.
As water resource and climate enthusiasts, it is essential to recognize the significance of structures like the Lower Tallahatch Y-10-34 Dam in safeguarding communities against flooding and preserving the ecological balance of the surrounding areas. By understanding its design, purpose, and regulatory framework, we can appreciate the role this dam plays in ensuring water security and resilience in the face of changing climate patterns. Looking ahead, continued support and stewardship of such infrastructure are crucial for sustainable water management practices in the region.

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.
