Located in Henry, Tennessee, the Thompson dam stands as a testament to human ingenuity and resource management. Completed in 1999, this private-owned Earth-type dam serves a primary purpose of "Other," with a hydraulic height of 23.3 feet and a structural height of 25 feet. With a storage capacity of 22 acre-feet, the dam's normal storage level is at 18 acre-feet, covering a surface area of 2 acres.

Despite its low hazard potential and moderate risk assessment, Thompson dam has not been rated for its condition. The dam's spillway type is "Uncontrolled," and it is not equipped with outlet gates. While it has not undergone any modifications since its completion, the dam is inspected every five years, with the last inspection taking place in April 2019. The surrounding area is not regulated by the state, and there are no associated structures or locks.

As climate change continues to impact water resources, the Thompson dam serves as a crucial infrastructure for water regulation and management in the region. Its presence contributes to the overall resilience of the area, providing a buffer against potential flooding events. With its uncontrolled spillway and lack of state jurisdiction, the dam represents a unique case study in private ownership and operation within the larger context of water resource management in Tennessee.
