Summary
This earth dam, constructed in 1966 by USDA NRCS, serves the primary purpose of flood risk reduction along Crab Tree Creek. Standing at a structural height of 48 feet and a hydraulic height of 17 feet, this dam has a storage capacity of 1487 acre-feet and covers a surface area of 19 acres within a drainage area of 3.64 square miles.
With a hazard potential classified as high and a condition assessment marked as satisfactory during the last inspection in January 2021, Jennings Creek #10 poses moderate risk according to the Tennessee Safe Dams Program. The dam lacks spillway gates and is of uncontrolled spillway type, emphasizing the importance of regular inspections and maintenance to ensure its structural integrity and safety. Despite its critical flood risk reduction role, this dam does not have an Emergency Action Plan (EAP) prepared or updated, highlighting the need for proactive risk management measures and emergency preparedness in the event of a potential breach.
Located in North Springs, Jennings Creek #10 stands as a significant asset in managing water resources and mitigating flood risks in the Jackson area. As climate change impacts continue to influence extreme weather events, the proper maintenance and monitoring of this dam are essential to safeguarding the community and surrounding environment from potential inundation. Through collaboration with regulatory agencies and adherence to inspection protocols, the local government can enhance the resilience of Jennings Creek #10 and ensure its continued effectiveness in protecting against flood disasters.

Dam Data Reference
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.
