Salas,Secretary F6deralEnergy Regulatory Commission 888First Sffeet,NE WashingtonD.C. 24426 Attention:Ann Ariel Vecchio DearSecretary Salas: This documenttransmits the U.S. Fish and Wildlife Service's(Service) Biological Opinion on the effectsto bull trout(Salvelinus confluentus),northern spotted owls (Srrlxoccidentalis caurina)and bald eagles(Haliaeetus leucocephalus) fromthe relicensingof the Lewis River HydroeiectricProjects: Merwin (FERC No. 935),Yale (FERC No. 2071),Swift No. 1 (FERC No. Zr 11),and swift No. 2 (FERCNo. 2213). Theaction that comprises this consultationunder theEndangered Species Act of 1973,as amended (16 U.S.C. l53I et seq.)is therelicensing of the Lewis-RiverHydroelectric Projects by the FederalEnergy Regulatory Commission and the interdependentactions contained in the SettlementAgreement (PacifiCorp et aL.2004e),dated November30,2004,and Washington Department of Ecology's401 Certifications. Consultationfor the relicensingof the Lewis River Plojectswas initiated by the Commission's letterto the Servicewhich was received in our officeon October11,2005. Based on our letter datedMarch15,2006,the deadline for completingthis consultationwas extended by mutual agreementuntil May 5, 2006. On June12,2006,with concurrenceby thelicensees,we submittedanother request for an extensionto SeptemberI,2006, to completethe detailedand complexanalyses associated with theproposed action. This revised completion date was ,rrpport"oby pacificorp andcowlitz Publicutility District. Becausethe Servicewas receiving criticatinformation regarding components of the SettlementAgreement up to the endof August, we werenot ableto miet the Septemberl,2006,completion date. There has been regular contactbetween pacifiCorp, Cowlitz public Utility District, andthe Serviceduring the drafting of this documentand,agreement betweenallparties on thetiming of completionof theBiological Opinion. TAxe PntDE.iffi'*-*;,j 'wfiMERTCAreq" SecretaryMagalie R. Salas Thefinal Biologicalevaluation, dated January 15,2}}s,proposed a"may affect,not likely to adverselyaffecl'determination for the northernspotted owl. The FWS doesnot concurwith this determinationbecause the Wildlife HabitatManagementPlans will allow the removalof suitable spottedowl habitatwhich would adverselyaffect this species.The Final BiologicalEvaluation uiro propored a "may affect,not likely to advefselyaffect" determinationfor the bald eag1e.The FWS doesnot concurwith this effectdetermination because of the indirecteffects associated with increasedrecreational use of the actionarea which is likely to disturbforaging bald eagles on the reservoirsand in salmonspawning grounds. We thereforeconducted a formal consultationon the spottedowi andbald eagle. Theenclosed Biological Opinion contains the Service'sconcurrence with your determinationthat the proposedaction "may affect,but is not likely to adveiselyaffect" designatedbull trout criticalhabitat. Becausethe Licenseesare uncertain where instream habitat enhancement projects will occur,the Servicewas unable to conductan analysisof effectsto spottedowls from this activity. Therefore,this aspectof theproposed action in relationto effectsto spottedowls mustbe addressed,as appropri ate, in a separatefuture section 7 consultationwhen site-specific conditionsare known. ThisBiological Opinion, therefore, does not includean analysisof effects of instreamhabitatenhancement projects on spottedowls. We wish to commendFrank Shrier of PacifiCorpand Diana Gritten-MacDonald of CowlitzPUD for their invaluableassistance in preparingthis BiologicalOpinion. Theywere critical to our understandingof the proposedaction and provided valuable assistance in their review of draft documentsfor accuracyandcompleteness. Their professionalcommitment to completingthe Biological Opinionon time andin a legally sufficientmanner was tremendously helpful and appreciatedby my staff. A completeadministrative record of this consultationis on file in the Service'sWestern WashingtonFish and Wildlife Office, in Lacey,Washington.

Low-relief rocky meadows and modest forested ridges marked by scattered cinder cones and shields are common landforms in Simcoe Mountains volcanic field. Mount Adams (elevation: 12,276 ft; 3,742 m) is centered 50 km west and 2.8 km higher than foreground meadow (elevation: 2,950 ft.; 900 m); its eruptions began ~520 ka, its upper cone was built in late Pleistocene, and several eruptions have taken place in the Holocene. Signal Peak (elevation: 5,100 ft; 1,555 m), 20 km west of camera, is one of largest and highest eruptive centers in Simcoe Mountains volcanic field; short-lived shield, built around 3.7 Ma, is seven times older than Mount Adams. 2015 U.S. Department of the Interior U.S. Geological Survey Contents Introductory Overview for Non-Geologists ...............................................................................................1 Introduction.....................................................................................................................................................2 Physiography, Environment, Boundary Surveys, and Access ......................................................6 Previous Geologic
