<br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />BACKGROUND <br /> <br />404 Clean Water Act Requirements, and passage of the Colorado Ute Indian Water Rights <br />Settlement Act. <br /> <br />Prior to the initiation of construction on ALP, new biological data caused Reclamation to <br />reinitiate formal consultation with the U.S. Fish and Wildlife Service (the Service) under <br />Section 7 of the Endangered Species Act (ESA). The new biological data concerned the <br />listing of the razorback sucker, critical habitat delineation for the Colorado squawfish and <br />razorback sucker, and several other issues regarding listed or species proposed for listing <br />under the ESA. As provided in Section 7 of the ESA, the Service provided Reclamation with <br />a draft Biological Opinion. The draft opinion indicated that ALP would jeopardize the <br />continued existence of the Colorado squawfish and that ALP provided no reasonable and <br />prudent alternatives (RP A) to avoid jeopardy. <br /> <br />On October 25, 1991, the Service issued a Final Biological Opinion for ALP on federally <br />listed endangered species. The Final Biological Opinion indicated that, based on current <br />development in the region, the full project would jeopardize the continued existence of the <br />Colorado squawfish but provided an RPA to avoid jeopardy which resulted from <br />negotiations between Reclamation and the Service and involved those in the project area and <br />San Juan Basin, both Indian and non-Indian. The Final Biological Opinion also contains <br />information on the razorback sucker, which was listed as an endangered species in <br />November 1991. <br /> <br />The RP A that avoids jeopardy to the endangered fish includes the following five elements: <br />(1) a Project that results in an initial annual depletion of 57,100 acre-feet; (2) seven years of <br />research to determine endangered fish habitat needs after which additional decisions will <br />be made to finalize the full scope of ALP completions; (3) operation of nearby Navajo Dam <br />and Reservoir to provide a wide range of flow conditions for the endangered fish; (4) a <br />guarantee that the Navajo Reservoir will be operated for the life of ALP to mimic the natural <br />hydrograph based on the research; and (5) legal protection for the Navajo Dam and <br />Reservoir releases to the San Juan River, through the endangered fish habitat to Lake Powell <br />and a commitment to develop a Recovery Implementation Program for the San Juan River. <br /> <br />2-4 <br />
