The creeper has never been found in lakes in the Northeast, but they have been discovered in small impoundments of run-of-river dams. (Nedeau, 2008)

Key Characteristics

Conservation Status


Creeper are river generalists and can be found in headwaters, deeper pools , and streams. It is likely more scarce in lower reaches of rivers, and absent from land-locked lakes.

Host Species

Largemouth bass, green sunfish, yellow perch, golden shiner, longnose dace, Atlantic sturgeon.

More Information


This species is found mostly in streams, and occasionally in lakes, including Lake Champlain. Rivers in which it occurs include the Black (Irasburg), Black (Ludlow), Connecticut, Lamoille, Missisquoi, Moose, Nulhegan, Poultney, West, and Winooski Rivers, Lewis and Otter Creeks, and Indian Brook (Colchester). The greatest densities were found in Lewis Creek and the lower Poultney River.

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.
