There may be no viable populations left.

FWS Digital Media Library — The U.S. Fish and Wildlife Service’s National Digital Library is a searchable collection of selected images, historical artifacts, audio clips, publications, and video. Linked life history provided courtesy of NatureServe Explorer. Records may include both recent and historical observations. This mussel was native to Alabama, Illinois, Indiana, Kentucky, Ohio, Pennsylvania, Tennessee, and West Virginia. By 1991 it was thought that there were about five populations remaining in Kentucky, Tennessee, and West Virginia. It is now thought to be extirpated from West Virginia, as the population there was a misidentification. Only a few specimens of the species have been observed recently. If any viable populations remain, they will be located in the Green River of Kentucky.
