As Appalachian raindrops merge and begin to trickle into streams, they eventually reach the Tennessee River.
The river has been carefully controlled by the Tennessee Valley Authority (TVA) since the 1930s and is a reservoir system harnessed by 35 dams.
The Tennessee River gallery in River Journey examines the river, comparing the wild Tennessee with these new, man-made environments. Explore habitats representing the Tennessee River, Reelfoot Lake and more.
