Summary
Built in 1997 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction, with a hydraulic height of 18.2 feet and a structural height of 46.1 feet. The dam has a NID storage capacity of 623 acre-feet and a normal storage capacity of 59 acre-feet, covering a surface area of 8.4 acres and draining a 1.24 square mile watershed.
Maintained and regulated by the Tennessee Safe Dams Program, Red Boiling Springs #4 has a high hazard potential but is currently in satisfactory condition, as per the last inspection in August 2020. The dam has an uncontrolled spillway type and is designed with stone core and rock foundation. Despite its moderate risk assessment score of 3, the dam has no outlet gates and is not associated with any other structures. With a captivating location along Salt Lick Creek, this dam is a vital asset for flood risk management in the area, serving as a testament to responsible water resource management in Macon County, 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.
