Global Range: Elk, Susquehanna, Bush, Patapsco, Patuxent, Potomac, Nanticoke, James, and Roanoke drainages in Virginia, West Virginia, Maryland, Delaware, and Pennsylvania (Kinziger et al. 2000). Atlantic Slope drainages from the Roanoke River system north to the lower Susquehanna River system; also an isolated population in the Nanticoke system in Maryland and Delaware; populations in the Rappahannock (Virginia) seem to represent another taxon, perhaps more closely related to C. girardi (as inferred from an allozyme data set) (Kinziger et al. 2000; Dave Neely, pers. comm., 2000).

Ecology
Habitat
Habitat Type: Freshwater
Comments: Habitat on the coastal plain is limited to cold, spring-fed streams (Kinziger et al. 2000).
Trusted
Migration
Non-Migrant: Yes. At least some populations of this species do not make significant seasonal migrations. Juvenile dispersal is not considered a migration.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.
