Taxonomy: Three subspecies of Nerodia fasciata are currently recognized (Crother 2012).  According to Conant and Collins (1998), N. f. confluens (Broad Banded Watersnake) is the subspecies found in Tennessee. 

Distribution: Gentry (1956) described the Southern Watersnake’s distribution in Tennessee as counties along the Mississippi River and especially common in Reelfoot Lake.  We believe this is likely still an accurate description, even though documented records are lacking for Tipton and Lauderdale counties.
