Range DescriptionThis species was once known from the upper Mississippi River drainage and the St. Lawrence River drainage, from western New York west to Michigan, Wisconsin, Iowa, and Kansas, south to Arkansas and Alabama. Historically occurred throughout much of the Ohio River drainage. Now sporadic occurrences in Ohio River and apparently extirpated from the Wabash and some other tributaries. Localized occurrences in the Green, Tennessee and Cumberland river reservoirs and a few Tennessee River tributaries.
