Endangered Status for the Diamond Darter and Designation of Critical Habitat

We, the U.S. Fish and Wildlife Service, propose to list the diamond darter (Crystallaria cincotta) as endangered under the Endangered Species Act of 1973, as amended (Act); and propose to designate critical habitat for the species. In total, approximately 197.1 river kilometers (122.5 river miles) are being proposed for designation as critical habitat. The proposed critical habitat is located in Kanawha and Clay Counties, West Virginia, and Edmonson, Hart, and Green Counties, Kentucky.
