USFWS is designating 15 reaches of the Colorado River system (Figure I -2 -1) as critical
habitat for the razorback sucker. In the Upper Basin, critical habitat designation includes
areas of the Green, Yampa, Duchesne, Colorado, White, Gunnison, and San Juan rivers.
Portions of the Colorado, Gila, Salt, and Verde rivers are being designated in the Lower
Basin. Of the historical range of the razorback sucker, 49 percent is being designated as
critical habitat. This area encompasses the major basins of the historical range.
