Bostick state:3 thv.t this canon is S01116thigg 1i1\:8 65 miles <br />long cD:ld is quite doep, the walls in plaoes being three Or fo-~u' <br />hundred feet high. A large n:mount of side drainage cornen in <br />to the river in this distc.llce throu:{h canons c.:,nd. arroyos. <br />.chota No. I!} shov~;s one of the :3mall arroyos cominr; into the main <br />canon neul' the head and is prolJably typi',Jal of h1.J]:ull'eds of <br />others. The "nestion Of whether the rber loses wa te,~ or not <br />in traversing this 65 miles of canon is a perplexing one and <br />has never been definitely set tIed. It seems to me that twc <br />automatic gages, one at the entranoe to, and one at the mouth <br />of the canon would, if o.L)eru.ted for s.everal months, throw some <br />1 ight on this cluestion thouGh any local ruins on the ".vater shed <br />tributary to the canon WOuld,to Gome extent, vitiate the records. <br />'.Phis quest ion is not 0119 of' merely acaderoic interest <br />d.ut has a distinct bee,ring on tho distribution of' vvuter in <br />District NO. 19. The Sizer ditch rights, transferred to the <br />Hip)lland Irril;u.tion Distri0t, are for 16.6 sec. ft. of water <br />of (lhte Jiiay ~ll, 1866 and for 7.4 sec. ft. of <dater of ci.ate April <br />1, 1884. 1'11i8 ditch, supplying the lli~'~hland Irrigation District <br />is 10 outed below the mouth of the Purgatoire canon and its 1866 <br />right, for 16.6 sec. ft. is senior tc many of the rights of the <br />ditches located above the canon. At what river-stage must these <br />upper di tches be shut dOtm tc supply the HiGhland District with <br />16.6 sec. ft. of 1866 water? <br />30loowhat conflicting opinions have been hazarded by <br />various engineers on this point, but it seems to me tllELt consider- <br />able study will be necess&l'Y before it can <I)e def'ini tely settled. <br />It is self-evident that if the river is ever ,Hlo<.,ad to ITa cOm- <br />pI etely dry at the head of the canon, and then l&.ter on w8,ter <br />
