About the Watershed

The upper part of this watershed is the location where the aquatic species of the north met those of the south during the last ice age. This unique geologic history has made this watershed the most diverse freshwater aquatic habitat in the world.  Many species of fish, freshwater mussels and invertebrates live in the drainages of the Tennessee River which are found no where else on earth. The Great Smoky Mountains to the East meet with the Lower Mississippi River Watershed to the West.   Historical losses have left the watershed with only 1967 square miles of wetlands (5% of the total area).
