Designation of Critical Habitat for the Trispot Darter

We, the U.S. Fish and Wildlife Service (Service), designate critical habitat for the trispot darter (Etheostoma trisella) under the Endangered Species Act of 1973 (Act), as amended. We are designating as critical habitat for this species six units, totaling approximately 175.4 miles (282.3 kilometers) of streams and rivers and 9,929 acres (4,018 hectares), in Calhoun, Cherokee, Etowah, and St. Clair Counties in Alabama; Gordon, Murray, and Whitfield Counties in Georgia; and Bradley and Polk Counties in Tennessee. This rule extends the Act's protections to the trispot darter's designated critical habitat.
