Tn'" draln"ge area was <br /> <br />used because the ratio of the peak discharges occurring at the West <br /> <br />Dolores and Dolores gages equals approximately the drainage are., ratio, <br /> <br />as :l1lustrated in Table 9. It was assumed that If'the I,est Dolores gage <br /> <br />ratio was valid, then the peak flow ratio of "Dolores River beiow the <br /> <br />confluence of Stoner Creek" to the Dolores gage 'imuld also equ.3.l <br /> <br />approximately the ratio of their respective dra:lnage areas, L,a. a ratlo <br /> <br />of 0.54. <br /> <br />T~!E 9 <br /> <br />k'INUAL PEAK DISCHARGE RATIO's <br /> <br />GAGE <br /> <br />D.A. <br /> <br />1941 <br /> <br />19f,2 <br /> <br />1943 <br /> <br />194f, <br /> <br />\Vest Dolores R. nr.
