Summary
Constructed in 1959 by the USDA NRCS, this earth dam with a height of 33 feet provides a storage capacity of 80 acre-feet. Despite being categorized as having low hazard potential, the dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections to ensure its structural integrity.
This dam, also known as Lt-10-2, falls under the ownership of the local government and primarily serves the purpose of flood risk reduction. The surrounding area, including New Albany, benefits from this essential infrastructure designed to mitigate potential flooding events. With a moderate risk assessment, the dam has not been rated for its condition, but it continues to play a crucial role in safeguarding the community against potential water-related disasters. As water resource and climate enthusiasts, understanding the intricacies of this dam's design, function, and regulatory oversight provides valuable insight into the intersection of infrastructure and environmental protection.

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.
