Despite complete control of the Arkansas River at John Martin <br /> <br />Dam, tremendous inflow from tributaries between the dam and the Co1orado- <br /> <br />Kansas state line produced unprecedented flows in the Arkansas River. <br /> <br />Wolf Creek produced a peak flow of 35,300 c.f.s. just above State Highway <br /> <br />117, about 9 and one-half miles southwest of Granada. This f1oodf1ow <br /> <br />breached the levee west of Granada and flooded the town with depths up to <br /> <br />6 feet. <br /> <br />15. Unit llydrographs. The unit hydrograph for Wolf Creek was <br /> <br />developed by synthetic methods because rainfall-discharge data are not <br />available to substantiate natural unit hydrographs. The synthetic unit <br /> <br />hydrograph was determined by use of the following formulas: <br /> <br />tp = 0.074 [CLLca)0.3] 0.669 <br />Sst <br /> <br />qp = 3,851 CSst)0.4542 <br /> <br />0.0264 r. 0 ] 0.9201 <br />A ~LLca) ..3 <br /> <br />6 <br />
