Summary

Built in 1988, this earth dam stands at a height of 41 feet and spans a length of 720 feet, with a storage capacity of 1090 acre-feet. Its primary purpose is flood risk reduction, serving as a key infrastructure to protect the surrounding area from potential flooding events.

With a drainage area of 2.43 square miles and a maximum discharge of 3460 cubic feet per second, the dam plays a crucial role in managing water flow and safeguarding the local community against flood hazards. While its hazard potential is significant, the risk assessment is categorized as moderate. The dam's spillway, with a width of 160 feet, ensures controlled water release during high flow events, further enhancing its flood protection capabilities.

Despite its age, the dam's condition assessment is not available, and the last recorded inspection was in 2015. The dam's emergency action plan status, risk management measures, and inundation maps are also not specified in the data. As water resource and climate enthusiasts, staying informed about the status and management of structures like the Lower Little Tallapoosa River 19 dam is crucial for understanding and addressing potential risks associated with water infrastructure in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
