Threatened Species Status for Kentucky Arrow Darter With 4(d) Rule; Proposed Rule

We, the U.S. Fish and Wildlife Service (Service), propose to list the Kentucky arrow darter (Etheostoma spilotum), a fish species from the upper Kentucky River basin in Kentucky, as a threatened species under the Endangered Species Act (Act). If we finalize this rule as proposed, it would extend the Act's protections to this species.
