Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for the Klamath River and Columbia River Populations of Bull Trout

We, the U.S. Fish and Wildlife Service (Service), designate critical habitat for the Klamath River and Columbia River populations of bull trout (Salvelinus confluentus) pursuant to the Endangered Species Act of 1973, as amended (Act). For the Klamath River and Columbia River populations of bull trout, the critical habitat designation includes approximately 1,748 miles (mi) (2,813 kilometers (km)) of streams and 61,235 acres (ac) (24,781 hectares (ha)) of lakes and marshes. We solicited data and comments from the public on all aspects of the proposed rule, including data on economic and other impacts of the designation.
