Summary
Constructed in 1965 by the USDA NRCS, this earth dam stands at a hydraulic height of 18 feet and a structural height of 50 feet, with a length of 445 feet and a storage capacity of 1447 acre-feet. With a drainage area of 4.43 square miles, this significant dam plays a key role in mitigating potential flooding in the region.
Managed and regulated by the Tennessee Safe Dams Program, Line Creek #3b has been inspected regularly, with its last assessment conducted in October 2020, indicating a satisfactory condition assessment. Despite its significant hazard potential, the dam is well-maintained and meets regulatory guidelines for safety. With a moderate risk assessment level of 3, the dam's risk management measures ensure its continued effectiveness in safeguarding the surrounding area from potential flooding events.
With no outlet gates and an uncontrolled spillway type, Line Creek #3b serves as a vital infrastructure for flood risk reduction in Clay County, Tennessee. As a key component of the local government's water resource management strategy, this dam embodies the collaborative efforts between state agencies and federal designers to ensure the safety and resilience of the community against natural disasters related to climate and water resource management.

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.
