Summary
Built in 1964, this earth dam stands at an impressive 66 feet in height with a hydraulic height of 26.3 feet, serving as a key defense against potential flooding in the area. With a storage capacity of 1782 acre-feet and a drainage area of 5.51 square miles, this dam plays a crucial role in protecting the surrounding community from water-related disasters.
Despite its high hazard potential, Jennings Creek #17 has been assessed as satisfactory in condition as of November 2020. Regular inspections affirm its structural integrity, with the Tennessee Safe Dams Program overseeing state regulation, permitting, inspection, and enforcement. The dam's spillway, classified as uncontrolled, adds an extra layer of protection in case of overflow, ensuring that water levels remain manageable during times of heightened risk. Its risk assessment labels it as moderate, further emphasizing the importance of ongoing monitoring and maintenance to uphold its protective capabilities for the community of North Springs.
As a focal point for water resource and climate enthusiasts, Jennings Creek #17 stands as a testament to the intricate balance between human engineering and natural forces. Its design by USDA NRCS and Dames and Moore, Inc. reflects a commitment to sustainable flood risk reduction, with a primary purpose of safeguarding the region against potential water hazards. With a history dating back to the 1960s, this earth dam continues to serve as a vital component of the local water management infrastructure, showcasing the intersection of environmental conservation and community safety in Tennessee's water landscape.

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.
