Justification:
Epioblasma personata has been assessed as Extinct. It was recorded historically from the Clinch River in the headwaters of the Tennessee River system, the White River (Wabash tributary), and in the low Wabash River at Posey Co., Indiana, as well as the Ohio River in Cincinnati. This species is known from shells only, no live individuals have been observed.

Geographic Range [top]

Range Description:	This species is globally extinct. It is recorded historically from the Clinch River in the headwaters of the Tennessee River system, the White River (Wabash tributary), and in the lower Wabash River at Posey Co., Indiana, as well as the Ohio River in Cincinnati (Parmalee and Bogan 1998). In Tennessee, it is known historically from the Clinch River and from the Cumberland River near Priestly Shoals, Davidson Co. (Parmalee and Bogan 1998). In Alabama, it was historically distributed throughout the Tennessee River, but has not been reported since the river was impounded (Mirarchi 2004, Williams et al. 2008). In Kentucky, it formerly occurred in the Green and Ohio Rivers (Cicerello and Schuster 2003). In Indiana, it was formerly distributed in the Wabash River (Cummings and Mayer 1997). In Ohio, it formerly occurred in the Ohio River in Cincinatti (Watters 1995).

Population [top]

Population:	This species has not been collected since the early 20th century (IUCN 1996). It historically occurred in the Ohio, Tennessee, Cumberland, and Wabah Rivers (Parmalee and Bogan 1998). In the Cumberland River, it ranged upstream to near the mouth of the Stones River (Parmalee and Bogan 1998). It occurred in most of the Tennessee River drainage, from headwaters in eastern Tennessee to the mouth of the Tennessee River, but a paucity of museum material suggests it was rare (Parmalee and Bogan 1998). All Alabama museum records were collected at Muscle Shoals, but it probably ranged across northern Alabama with the most recent material from 1924 (Williams et al. 2008).
