Summary
Built in 1964 and designed by the USDA NRCS, this earth dam stands at a structural height of 42.2 feet and has a length of 343 feet. It serves the primary purpose of flood risk reduction, with a capacity to store 923 acre-feet of water from the Sycamore Fork river or stream.
Managed by the local government and regulated by the Tennessee Safe Dams Program, Jennings Creek #4 has a low hazard potential and is currently in satisfactory condition as of the last inspection in December 2020. Despite its moderate risk assessment, the dam maintains a secure position within the community, with no associated structures or outlet gates. With a designated inspection frequency of 3 years, this dam remains a critical asset in protecting the surrounding area from potential flooding events, showcasing the importance of proper water resource management and climate resilience in the region.
As part of the Louisville District, Jennings Creek #4 contributes to the overall water infrastructure in the area, providing essential flood protection measures for the residents of Whitleyville and beyond. With its historical significance and ongoing regulatory oversight, this dam serves as a vital component in the sustainable management of water resources in Tennessee, highlighting the collaborative efforts between local and federal agencies to ensure the safety and well-being of the community 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.
