Range Description

This species ranges throughout the Mississippian Region, and from the Great Lakes into western New York state, west to Minnesota, and into southern Canada; it also occurs in peninsular Florida, Apalachicolan region, and in the western Gulf Coastal region in most drainages in Louisiana to the Rio Grande system in Texas (Johnson 1999).

Surveys have found this species to be locally abundant in drainage systems in the southern US (White and White 1977), and abundant in Ohio in modified habitat (Smith et al. 2002). However, there is evidence of local extirpations in the Red River drainage of Texas and Oklahoma since the early 20th century, where the species has been reduced from four sites to just one (Vaughn 1999).
