Summary
This 11.4 feet high structure has a hydraulic height of 7.3 feet and a storage capacity of 66 acre-feet. With a normal storage capacity of 23 acre-feet, the lake covers a surface area of 9.2 acres and has a spillway type classified as uncontrolled. Despite being associated with low hazard potential and a moderate risk assessment rating, the dam's condition has not been rated and it has not been inspected since August 2017.
Owned by a private entity, Creswell Lake#20 does not fall under state jurisdiction or regulation. The dam, situated in the Memphis District of the US Army Corps of Engineers, does not have any associated locks or outlets. While it lacks a designated purpose and has not been assessed for its condition, the structure's risk assessment suggests a moderate level of risk. The dam's emergency action plan status and inundation maps preparedness are unknown, highlighting potential gaps in preparedness for any unforeseen events.
Despite its age and lack of recent inspection, Creswell Lake#20 remains a notable feature in the Tennessee landscape, serving as a reminder of the importance of maintaining and monitoring water resources. With its unique characteristics and risk profile, this dam presents an opportunity for further research and evaluation to ensure the safety and sustainability of the surrounding area's water supply and ecosystems. For water resource and climate enthusiasts, Creswell Lake#20 offers a fascinating case study in dam infrastructure management and the intersection of private ownership with public safety and environmental concerns.

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.
