Global Range: (<100 square km (less than about 40 square miles)) This species was historically found in the Conasauga River in Tennessee and Georgia, the Coosawatee, Oostanaula, Coosa, and Etowah Rivers in Georgia, and the Coosa River and following tributaries in Alabama: Big Wills, Terrapin, Big Canoe, Yellowleaf, Waxahatchee, Talledega, and Hatchet creeks (USFWS, 1999; 2003; 2009; 2010). In the Coosa River basin in Georgia, it is known historically from the Coosa, Etowah, Oostanaula, Conasauga, and Coosawattee River drainages (Williams and Hughes, 1998). Recently, fresh dead shells were collected in the upper Conasauga River above Dalton, Georgia (USFWS, 1999; 2003) and a single large specimen found alive also in the Conasauga River in Georgia (P. Johnson, TN Aquarium Research Institute, pers. comm.). The species has been extirpated from Alabama (Mirarchi et al., 2004; Mirarchi, 2004) where it was endemic to the Mobile basin; and nearly so in Tennessee (see Johnson et al., 2005) and Georgia (Williams et al., 2008).
