Range Description

In the United States, this species occurs in California, Nevada, Oregon and Washington and is possibly extirpated from Utah (Oliver and Bosworth 1999).

In Canada, this species occurs in British Columbia (NatureServe 2009).

The geographic range of this clade is in question because of the taxonomic uncertainty that has plagued the genus Anodonta. This species has been confused with A. beringiana in the northern part of its range and with A. californiensis in the southern part of its range (Nedeau et al. 2009).
