The SPF hydro graphs for the locations <br /> <br />of "Dolores River below the confluence of Stone,r Creek" and "West Dolores <br /> <br />River at Mouth" were calculated in the same tnEl:tlne,r. Figures 11, 12, and <br /> <br />13 illustrate the computed hydrcgraphs. <br /> <br />The SPF thunderstorm was applied to the Lost Canyon Creek basin <br /> <br />];JOde1, and using the loss data shown on Table ";, ,'1 SPF hydrograph was <br /> <br />computed and is shown on Figure 14. <br /> <br />Various peak discharge-frequency values clll':ulated for each of the <br /> <br />four index point locations arc tabulated in Table 10. <br /> <br /> TABLE 10 <br /> PEAK DISCHARGES (C.F.S,J.. <br />12<l.ex ll'oint _Locat}on D.A. lO-Yr 50-Yr 10O--Yr ~OO'Jr SPF <br />-- '-' ----- <br />Dolores River below <br />the confluence of <br />Stoner Creek 270 3700 6000 7500 20000 16000 <br />Wcst lJolores River /ISoo ~~o <br />at Houth 167 2300 3800 /,800 ~) <br />Dolores River below <br />the confluence of 11<:"0,,, <br />Lost Canyon Ck. 567 6800 ,10000 1l.500 36000 28500 <br />Lost Canyon Creck <br />at HOllth 72 600 1700 2500 5400 5500 <br /> 13 <br />
