New York State Distribution [-]
There are 3 general areas of occupancy in New York, reflecting the routes of entry into the state: the Allegheny, Great Lakes, and Champlain basins (Strayer and Jirka 1997). Within the Allegheny drainage the species is known from the Allegheny River in the vicinity of Olean and Portville, as well as 2 of its major tributaries, the Cassadaga and Conewango Creeks. In the Great Lakes basin, there are old records from Lake Erie, but more recently a thriving population was located in Tonawanda Creek along the border of Niagara and Erie counties (Marangelo and Strayer 2000). Several pre-1970 records are also known from the Erie Canal and Oneida Lake, but apparently the species has not been found there more recently (Strayer and Jirka 1997). The St. Lawrence basin population seems to be the most precarious, since only pre-1970 records are known from the St. Lawrence River (Strayer and Jirka 1997), and only old weathered shells have been recently found in 2 of its tributaries, the Grass and Oswegatchie Rivers. Finally, a small population also occurs on the Poultney River, a tributary of Lake Champlain. Sauger was found to be the primary host for this mussel (Khym and Layzer 2000) and the mussel's distribution within the state does follow the general distribution this rare fish.

Global Distribution [-]
This species is widespread in the eastern and central U.S. and Canada, occurring from the Great Lakes basin south into the Mississippi River drainage to Louisiana and in some Gulf Coast drainages (Parmalee and Bogan 1998).
