Comments: One viable population exists in the Estill Fork of the Paint Rock River. This one population appears to be limited to a reach of stream less than one mile in length. Dead shells are occasionally found throughout the upper Paint Rock River and its tributaries (Doug Shelton, pers. obs. 1995). Even in the 1970s and 1980s, few specimens were collected (2 specimens in Paint Rock River below Hurricane Creek; 6 fresh dead specimens at Estill Fork near Freedom Bridge) and numerous surveys have uncovered no specimens at all in the Paint Rock River, Hurricane Creek, and Estill Fork (see USFWS, 1984).
