Summary
Built in 1977, this dam on Cold Branch has a hydraulic height of 2 feet and a structural height of 227 feet, with a length of 3393 feet. It has a storage capacity of 32,945 acre-feet and covers a surface area of 12 acres, serving as a vital resource for water management in the area.
Managed by the Tennessee Safe Dams Program, Solutia #15 is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. Despite its low hazard potential and satisfactory condition as assessed in 2019, the dam is subject to moderate risk (3) according to a risk assessment. Emergency preparedness measures like an Emergency Action Plan (EAP) and inundation maps are not currently available, highlighting the need for continued monitoring and risk management.
With its critical role in water resource management and the potential risks associated with its operation, Solutia #15 underscores the importance of proactive monitoring and maintenance to ensure the safety of the surrounding community and the integrity of the dam structure. As climate change continues to impact water resources, dams like Solutia #15 will play a crucial role in mitigating the effects of extreme weather events and ensuring water security for the region.

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.
