Range
Known from three drainages in far western Vermont. There is an historic collection from the Clyde River in northeastern Vermont.
Distribution map has locations where this species has been documented and digitized into the atlas database. Systematic surveys have not been conducted for many species and those surveys that have been conducted have been largely focused on endangered species. Therefore, in some cases, the actual distribution of freshwater mussels may be more extensive than what is presented here. Shaded areas are watershed sub-basins and river main stems are shown.
