Option 2 would affect the most <br />acreage including 0.37 acres of wetland and 0.82 acres of mixed conifer. Road Corridor Option 3 <br />would affect median acreage, the least mixed conifer (0.71 acres), and the most wetland (0.48 acres). <br /> <br />4.7.3 Cumulative Impacts <br /> <br />Under all three alternatives, (A, B, and C) more trampling by recreationists and displacement of <br />vegetation would occur with increased human use of the area. <br /> <br /> <br />4.7.4 Mitigation and Enhancements Summary <br /> <br />In addition to the wetlands mitigation discussed in Section 4.5.4, under Alternatives Band C, <br />disturbed areas would be regraded and reseeded with a native grass mixture. <br /> <br />4.7.5 Unavoidable Adverse Impacts <br /> <br />Under Alternatives :s and C, existing vegetation communities affected by inundation or facility <br />construction would be permanently lost. Reclamation of disturbed borrow areas could return these <br />areas to aesthetically pleasing and functioning vegetation communities. <br /> <br />4.7.6 Irreversible and Irretrievable Commitment of Resources <br /> <br />Acreage which would be inundated by the proposed expansion would be irreversibly committed to <br />water storage. As a result, this acreage would no longer be available to support wetlands, upland <br />meadows, or coniferous forest. Likewise, new roads that are developed would commit resources for <br />the long-term unless reclaimed. Furthermore, timber resources currently existing proximal to the <br />reservoir would also be irretrievable once harvested. <br /> <br />4.8 WILDLIFE/FISHERIES <br /> <br />4.8.1 Introduction <br /> <br />This section addresses potential direct and indirect impacts that would be associated with the <br />alternatives addressed by this EIS. These impacts are discussed below for all wildlife, with particular <br />emphasis placed on potential effects to wildlife species of concern including: <br /> <br />. Big game <br />. Raptors <br />. Trout <br />. and Federal Threatened, Endangered, or Candidate species <br /> <br />4.8.2 Direct and Indirect Impacts <br /> <br />4.8.2.1 Alternetive A . No Actioo <br /> <br />Under the Alternative A, the project area would essentially remain in its existing state. As a result, <br />future habitat conditions and wildlife use of the project area would be similar to those currently <br />existing at the reservoir site, assuming there are no major alterations in current land use activities. <br />Stream habitat in the Puppy Dog Lake channel would continue to be degraded by high spring flows, <br />and no long-term fisheries pool would be maintained for fisheries in the reservoir itself. <br /> <br />:;-,'i:':",::-.%<::;:~:::<::I;~~.v...<::~%:-~:':'(~:;::..:.m.m;::::;:o::x<<=;:;>?x::":;::;:v.:::~.#.:~:<~~-:::>;:=::;;;x=:::,'.=:::;<~;":::':;^-"::::::;:::::::;~~:<~~~:&=::;':;'";-.-O:;;~:=":::W::;:::;~':>;;';::=:.:":-:l$m:-:>,':-..'::::;:,~':::::;':':;:x-:<:;:=:~.~:",~::.}:.:::=::;;:.:::.x~.~x <br /> <br />Srylmber 1993 <br /> <br />Page 4.25 <br />
