The in-stream flow rights evaltlated arc based on the preliminary flow <br />,recommendations provided by CDOWIBLM (Appetidix AA) and more recent preliminary <br />recolTllllendaticn provided by CWCB (CWCB MemOrandum cfNovember 16, 2000). The <br />analysis is intended to evaluate the polential impacts,o! such in-stream flow rights on future water <br />right applicants jur.ior to in-stream flow rights, Table 3.3 3umman7.es the preliminary flow <br />recolTllllefldations ofCDOWIBLM and eWCB. lMse rewx:unendal.ions have not yet been <br />adopled,byeWeB, Additional modification ofin-stream flow recom..nendations by the agencies <br />is anticipated. . <br /> <br />TABLES,3 <br /> <br />CDOW/Bl.M PRELIMINARY CWCB PRELIMINARY <br />FLOW RECOMMENDATIONS .

Since existing senior water rights are grea.ter than ~ther the <br />CDOWIBLM or CWCB recommendations during t/1e period orriver cllll (April 15 to October 1) <br />the recommendations would essentia.11y have no eff~et durir.g t!lis period of time, A3 indicated in <br />Figurtl 3.3, the CWCS recommendation would be slightly more restrictive that the CDOWIBLM <br />rec;om.m~ndation, On the bl\Sis cfFigure 3.3, the diversion wi:ldow for jllnior rights would be <br />limited (0 a.bout II 145-day period ir. a low flow year; 120 days from March to the Cltd of June, the <br />. first wee..'< in October, and the first half ofNo"em~. During low flow years, flow in the San <br />Migu=l falls below 65 efs from mid-November thr$gh the end of February. Therefore, no <br />diversion of water would be a.11owed during this pei;od of time by water right holders junior to a."1 <br />in-stream flow tiling. i <br /> <br />3-9, <br /> <br />P.4 <br /> <br /> <br />e <br /> <br />e <br /> <br />e <br />
