The Upper Colorado River Basin is home to 14 native fish species, including the endangered humpback chub (Gila cypha), bonytail (Gila elegans), Colorado pikeminnow (Ptychocheilus lucius), and razorback sucker (Xyrauchen texanus). These federally endangered fish are found only in the Colorado River system. The Upper Colorado River Endangered Fish Recovery Program is a multi-agency partnership to recover these four big-river fish while water use and development continues to meet human needs in compliance with interstate compacts and applicable federal and state laws.
