Chickamauga Lake is a reservoir in the United States along the Tennessee River created when the Chickamauga Dam, as part of the Tennessee Valley Authority, was completed in 1940.

The lake is commonly used for recreational and outdoor activities, especially at the southern end, due to the high population density surrounding it.

Actual lake levels vary due to weather conditions and power needs.
