Range
editAlthough this species was once very widespread, most of the decline documented in the range of the species occurred historically; this species was historically widespread in the Mississippi River drainage in Minnesota, Wisconsin, Iowa, Illinois, Indiana, Missouri, Kentucky, and Arkansas. Populations are believed to be extirpated from the Upper Mississippi as well as significantly reduced in the St. Francis and Ohio River drainages but populations have since expanded in the latter two rivers as well as found in the Lower Mississippi River. Populations are extant in Illinois, Indiana, Kentucky, Arkansas, Mississippi, and the borders of Missouri and Louisiana. [3]
