Geographic Distribution
I. greeleyi can be found in the Ohio River basin. This includes the Allegheny River, the headwaters of the Kentucky, Green, and Cumberland rivers, and the Tennessee River tributaries (NatureServe). I. greeleyi can be found usually upstream from the Ohio lamprey (Ichthyomyzon bdellium)(www.naturalheritage.state.pa.us/factsheet). The states in which I. greeleyi can be found include southwestern New York (Smith), northwestern Pennsylvania (Cooper), eastern Ohio (Trautman), Kentucky (Burr and Warren), West Virginia (Stauffer), Tennessee (Etnier and Starnes), northern Alabama (Mettee), northern Georgia, and western Northern Carolina (Menhinick). I. greeleyi populations have been depleted and even extirpated from some locations in Pennsylvania, West Virginia, and Kentucky. This is thought to be due to pollution (caused by runoff with cow manure, sewage, fertilizer, and pesticides), siltation (caused by overgrazing, row cropping and land clearing), and stream alteration (caused by dams) (NatureServe).

Famous quotes containing the word distribution:
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
