Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for Sharpnose Shiner and Smalleye Shiner

We, the U.S. Fish and Wildlife Service, designate critical habitat for the sharpnose shiner (Notropis oxyrhynchus) and smalleye shiner (N. buccula) under the Endangered Species Act. In total, approximately 1,002 river kilometers (623 river miles) of river segments occupied by the species in Baylor, Crosby, Fisher, Garza, Haskell, Kent, King, Knox, Stonewall, Throckmorton, and Young Counties, in the upper Brazos River basin of Texas, fall within the boundaries of the critical habitat designation. The effect of this regulation is to designate critical habitat for sharpnose shiner and smalleye shiner under the Endangered Species Act.
