Note: For many non-migratory species, occurrences are roughly equivalent to populations.

Comments: Clench and Turner (1956) list the Flint (Decatur and Seminole Cos., Georgia), Chattahoochee (Troup Co., Georgia and Houston Co., Alabama), and Apalachicola (Calhoun Co., Florida) River drainages. In Georgia (Dillon et al., 2006), North Carolina (Dillon et al., 2006), and South Carolina (Dillon and Stewart, 2003), this species is ubiquitous. In Alabama, it is found throughout the state and is common (Mirarchi, 2004). In the Cuyahoga Valley National Park (between Cleveland and Akron, Ohio), this species was recently found in three ponds and a ackwater area in Adam Run part of the mainstem in the park (Smith et al., 2002). In Indiana, Pyron et al. (2008) found it in 16 of 123 sites surveyed across the state compared to Goodrich and van der Schalie (1944) who reported it present only in northern Indiana counties. Dillon and Benfield (1982) documented this species in the New River in southwestern Virginia and Northwestern North Carolina. In Pennsylvania, it occurs in the Delaware, Ohio and Susquehanna basins (Evans and Ray, 2010). Dawley (1965) lists North Carolina distribution as across the entire state. In Missouri, it is distributed in Lowland, Ozark (mainly southeast division), and Prairie (Mississippi and Lower Missouri divisions) in Boone, Butler, Carter, Dunklin, Henry, Jackson, McDonald, Mississippi, Montgomery, New Madrid, Oregon, Pike, Polk, Ralls, Reynolds, Ripley, St. Charles, Scott, Shannon, Stoddard, Warren, Wayne Cos. (Wu et al., 1997). It occurs in the White River drainage, Arkansas, below Beaver Reservoir dam, Carrol Co. (Gordon, 1982). Minton et al. (2008) documented it in the Bayou Bartholomew drainage in Arkansas; where it was the most abundant species. It occurs in ponds and creeks and the Savannah River on property of the Savannah River Power Plant, Aiken, South Carolina (Wood, 1982). In Kentucky it has been documented in the Green River (creek in Casey Co., pond in Mason Co., Rockhouse Slough) drainage (Branson and Batch, 1983); as well as the Kentucky (pond in Madison Co.) and Licking (Licking River) (see also Rosewater, 1959) River drainages (Branson and Batch, 1981). Branson and Batch (1987) documented it in Kentucky in the Cumberland (Bert T. Combs Pond), Licking (Slate Creek, Licking River), Green (Roundabout Swamp), and Kentucky (West Fork Otter Creek) drainages but indicate it probably occurs statewide. Blair and Sickel (1986) documented it in 1 of 44 sites (Duncan Lake in Kentucky) surveyed in Land Between the Lakes (national recreation area between Cumberland River (Lake Berkeley) and Tennessee River (Kentucky Lake)) in Kentucky and Tennessee. Subspecies championi occurs in Nicaragua in Polvon, Chontales; in Mexico in a lake near Uruapan in Michoacan and in Tepic, Nayarit; and Panama in Bigabo (Thompson, 2008). Branson (1966) lists one site each in the Spring River basin of Kansas and Missouri.
