Mycommentu11l as followl: <br /> <br /> <br />COll1I1l~tal <br /> <br />The lISOlllIblc aild P.l1IdClllt A1lMnlllhe (RPA) includes ~ requirement that 300,000 AF of Water ' <br />be ma Ivajliblli for fish relCll5es 96'1: of the time. This requiremenl predetennines what tlDwS I <br />!.be S Juan Rivet Biology Committee can recommend for the benefit of the species and to allow <br />water eveloptnentto continue, !.be dua1goals of the San luan Recovery Implementation <br />Pro m. Tbe.latiguage rlllardin, the water storod for fISh releases should be chanscd to allow <br />the 81 101>' Com~ltce to determine the required flowl!OCimc for timing, magnitude and duration , <br />of III e (both seuonal and annual) based on the results Cof the ongoing research effon. <br /> <br />Pu.rth ; thiuuqll~nt al.o asSunte3 that the 300,000 AI' relcLle is necdlld eveq year. Delli <br />flOm e San Juan: Ilcsearch may show lbal the release should not be made in some years becaiue \ <br />of little or DO tienefitlO the fish. An eumplo would be in dry water years when the amount Df <br />total w in the river would nOI be sufficienlto cle8ll the spawning substrate. II may be more <br />beDefi ial to Rlake a release during peak flow times in lUgher water years when the maximum <br />- ",,,,,,,.,. w..... 0....1" ow. _. !hi. _loa' ~""l,... ,,'" flow . <br />amou made ~Vailable each year. II may be more appropriate to have an average annual amount <br />of w r reserv.ed to aUow fOt srcatet manipulation in concur with me lIatural runoff patterns <br />based n Ihe water availability (e.g. wet. averase or dry condition). <br /> <br />Finall ,il is ~sslble co determine the percent cxceedencc of OCC:lImnce of tltis amount of WIler <br />ill pre ious Y~'F.' it is not possible CO predict with the a<:<;urac)' ~pcciiied that the wllter will be <br />avail 10 in th~ fultlrc due to naUll:lIl vllliation in the hydrologic cycle. This storage for <br />COlupllUlCe wilh the RPA would requirc that the water is available every year for the fUit 22 <br />yom ~r con ltIiction Df Ihe project. Only in Ibe 23rd year after project construction could a <br />flow year with ICSi than 300,000 AP occur. This means thaI no depletions over 57.100 Af CaD <br />occur Unlen c 300.000 AP is guaranteed at the rate of 96 years out of 100. n" Biological <br /> <br />1401 RiVerside,. e. Suite 3.
