Summary
Constructed in 1962, this earthen dam stands at a hydraulic height of 46.9 feet and spans a length of 1100 feet, with a storage capacity of 390 acre-feet. The dam's primary purpose and associated structures are not specified, but it is regulated by the Tennessee Safe Dams Program and subject to state permitting, inspection, and enforcement.
Despite its low hazard potential and satisfactory condition assessment, Solutia #11 carries a moderate risk rating, indicating a level 3 risk assessment. The dam does not have an emergency action plan (EAP) prepared, and there is no information available on its compliance with EAP guidelines or the existence of inundation maps. The last inspection was conducted in March 2019, with a routine inspection frequency of 3 years, suggesting a commitment to monitoring and maintaining the dam's integrity.
As water resource and climate enthusiasts, the data on Solutia #11 provides valuable insights into the management of dams in Tennessee. The dam's location, design, and regulatory oversight offer a glimpse into the complexities of balancing water storage needs with safety and environmental considerations. While Solutia #11 currently presents a low hazard potential, the moderate risk rating underscores the importance of ongoing monitoring and risk management to ensure the safety and resilience of this essential infrastructure in the face of changing climate conditions.

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.
