Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for Kentucky Arrow Darter

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for the Kentucky arrow darter (Etheostoma spilotum) under the Endangered Species Act (Act). In total, approximately 395 stream kilometers (skm) (246 stream miles (smi)) are being proposed for designation of critical habitat for the Kentucky arrow darter in Breathitt, Clay, Harlan, Jackson, Knott, Lee, Leslie, Owsley, Perry, and Wolfe Counties, Kentucky. If we finalize this rule as proposed, it would extend the Act's protections to this species' critical habitat. We also announce the availability of our draft economic analysis of the proposed designation.
