Summary
Built in 1960 by USDA NRCS, this Earth-type dam stands at a structural height of 28.3 feet and serves the primary purpose of flood risk reduction. Situated on the UPPER THOMPSON CREEK, this dam has a hydraulic height of 21.3 feet and a storage capacity of 3242 acre-feet, with a normal storage level of 1470 acre-feet.
Managed by the TENNESSEE SAFE DAMS PROGRAM, Thompson Creek #4 is regulated, permitted, inspected, and enforced by the state of Tennessee. Despite its significant hazard potential, the dam is currently in satisfactory condition according to the last inspection conducted in December 2019. With a moderate risk assessment rating of 3, Thompson Creek #4 poses a manageable level of risk, and no Emergency Action Plan (EAP) has been prepared as of now.
This dam not only contributes to flood risk reduction but also provides benefits for fish and wildlife habitat and recreational activities in the area. Serving as a vital infrastructure for water resource management in Weakley County, Thompson Creek #4 stands as a testament to the collaborative efforts between state and federal agencies in ensuring the safety and functionality of important water structures in Tennessee.

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.
