Designation of Critical Habitat for Alabama Sturgeon (Scaphirhynchus suttkusi): Proposed rule.

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for the Alabama sturgeon (Scaphirhynchus suttkusi) under the Endangered Species Act of 1973, as amended (Act). In total, approximately 524 kilometers (326 miles) of river are proposed as critical habitat. The proposed critical habitat includes portions of the Alabama and Cahaba Rivers in Autauga, Baldwin, Bibb, Clarke, Dallas, Lowndes, Monroe, Perry, and Wilcox Counties, in Alabama.
