We, the U.S. Fish and Wildlife Service (Service), designate critical habitat for the Kootenai River population of the white sturgeon (Acipenser transmontanus) (Kootenai sturgeon) pursuant to the Endangered Species Act of 1973, as amended (Act). In total, approximately, 6.9 river miles (RM) (11.1 river kilometers (RKM)) of the Kootenai River fall within the boundaries of the critical habitat designation located in Boundary County, Idaho. This designation is in addition to the 11.2 miles (18 kilometers) of the Kootenai River already designated as critical habitat for the Kootenai sturgeon.
