Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: > 300
Comments: The species has been introduced to Massachusetts (University of Massachusetts campus pond, Amherst) and Rhode Island (University of Rhode Island campus pond, Kingston) (Smith, 2000). Recently it was found at a single in the Catawba River in North Carolina (Alderman, 2005). It has been introduced to all North Carolina river basins in the Piedmont Plateau and Coastal Plain (Cooper and Armstrong, 2007; Simmons and Fraley, 2010). It has been introduced in a variety of aquatic habitats in lentic areas in South Carolina across much of the state (Eversole and Jones, 2004).In Georgia, it has been introduced into a single stream in downtown Athens and a highly disturbed urban stream in Gwinnett Co. and an urban stream in the Etowah River system (Skelton, 2010). In the Cumberland Plateau it occurs from introductions in the Black Warrior River system in Jefferson Co., Alabama. (Bouchard, 1974). In Kentucky, it has a distribution almost identical to Procambarus viaeviridis; known from the floodplains of the extreme lower Tennessee, lower Ohio, and Mississippi Rivers and from tributaries of the Mississippi River in the extreme western portion of the state (Taylor and Schuster, 2004). In Indiana, it was collected in 2000 from Lake Michigan in Indiana and it has spread into the West Branch of the Grand Calamet River (Simon, 2001) and more recently in East Branch Calumet River in Lake Co. (Simon et al., 2005). In Ohio, it was introduced in the western end of Sandusky Bay, a fish hatchery at Denison University, and the Grand River upstream of Harpersfield Dam (Thoma and Jezerinac, 2000). In Missouri, it occurs widely in the Lowland Faunal Region (Pflieger, 1996). In Illinois it is known from lowland habitats in the extreme southern Illinois counties of Alexander, Jackson, massac, Pope, Pulaski, and Union (Page, 1985) and recently the North branch Chicago River in Chicago, Cook Co.; hundreds of km north (Taylor and Tucker, 2005). In Alabama, it is known from the Tennessee, Mobile, Black Warrior, Cahaba, Coosa, Tallapoosa, and Escambia River systems (Schuster and Taylor, 2004) as well as Alabama, Pascagoula, and Tombigbee drainages (Schuster et al., 2008). In Texas, the natural range is throughout the eastern portion along the coastal plain and upstream within rivers thatr flow from the Edwards Plateau into the Gulf (Johnson and Johnson, 2008). This species has been documented in Cuatro Cienegas, Coahuila, Mexico (Dinger et al., 2005).
