Summary
Constructed in 1962 by the USDA NRCS, this earth dam stands at a structural height of 44.5 feet and serves the primary purpose of flood risk reduction along Hicks Branch. With a hydraulic height of 20.5 feet and a storage capacity of 528 acre-feet, this dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding events.
Managed by the Tennessee Safe Dams Program, Jennings Creek #3 is classified as having a high hazard potential due to its location and design. Despite this classification, the dam's condition assessment in January 2021 reported it as satisfactory, with regular inspections ensuring its safety and functionality. With a drainage area of 1.6 square miles and a normal storage capacity of 58 acre-feet, this dam continues to play a significant role in water resource management within Jackson County.
As a key component of flood risk reduction efforts in the region, Jennings Creek #3 remains a critical infrastructure asset in safeguarding communities and ecosystems from the impacts of extreme weather events. Supported by the Natural Resources Conservation Service and meeting state regulatory standards, this dam is a testament to the importance of proactive water resource management in mitigating climate-related risks and enhancing overall resilience in the face of changing environmental 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.
