Summary
Built in 1961 by the USDA NRCS, this dam stands at a structural height of 46.5 feet with a hydraulic height of 18 feet, providing flood risk reduction for the Brannon Creek watershed. With a storage capacity of 1136 acre-feet and a normal storage level of 91 acre-feet, this dam covers a surface area of 13.7 acres and serves a drainage area of 4.23 square miles.
Managed by the Tennessee Safe Dams Program, the dam has a low hazard potential and is considered to be in satisfactory condition as of the last assessment in January 2020. Although it does not have an Emergency Action Plan (EAP) in place, the dam is inspected every three years to ensure its safety and functionality. While the dam has no outlet gates, its spillway type is listed as "Uncontrolled," with a spillway width of 0 feet. Despite being a moderate risk structure, Jennings Creek #5 continues to play a crucial role in flood risk reduction in the area.
Overall, Jennings Creek #5 serves as a vital piece of infrastructure in the region, providing flood protection and water resource management for the surrounding community. With its earth construction and stone core design, this dam has stood the test of time since its completion in 1961. As climate change continues to impact water resources, the importance of structures like Jennings Creek #5 in mitigating flood risks and ensuring water security only grows, highlighting the ongoing need for effective dam management and regulation in Tennessee.

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.
