Designation of Critical Habitat for the Oregon Chub (Oregonichthys crameri): Proposed rule.

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for the Oregon chub (Oregonichthys crameri) pursuant to the Endangered Species Act of 1973, as amended (Act). In total, approximately 53 hectares (ha) (132 acres (ac)) fall within the boundaries of the proposed critical habitat designation. The proposed critical habitat is located in Benton, Lane, Linn, and Marion Counties, Oregon.
