<br />LAKE CREEK <br /> <br />Drainage <br />Area (Sq. Mi.) <br /> <br />Peak Discharges (cfs) <br />10 50 100 500 <br /> <br />Location <br /> <br />1. Downstream Limit <br /> <br />64.0 <br />55.4 <br /> <br />2389 2972 <br />2200 2720 <br /> <br />3210 <br />2932 <br /> <br />3739 <br />3405 <br /> <br />2. Upstream Limit <br /> <br />1. Qs = 0.8822 Qg + 625 <br />2. Qs = 0.7872 Qg + 625 <br /> <br />Comparison of the previous results with other analyses in the <br />basin (See Figure 5) show poor agreement. The Lake Creek <br />watershed, due to its steepness, high percentage of rock cutcrop <br />in the higher elevations (See Soils Map in Appendix) and its <br />sparcity of vegetation, produces a larger volume and quantity of <br />snowmelt runoff than can be expected from the other basins which <br />were used in this comparison. The Lake Creek results, therefore, <br />appear reasonable. Although, the U.S. Forest Service has <br />monitored the Lake Creek Bas in (1965 - 1977) for a snow fence <br />study, the results of their monitoring as explained in the Other <br />Studies Section were not useful to this study. <br /> <br />Arkansas River <br /> <br />h <br /> <br />The hydrologic analyses for the Arkansas River were accomplished <br />by analyzing available streamgage records at the Granite gage <br />(07086000) located 4.8 miles downstream of the study site. For <br />this analysis, records for the period 1910 to 1979 were analyzed <br />using the procedures recommended by WRC Bulletin 17. The 1957 <br />flood was considered a high outlier in the calculations. Due to <br />numerous and complex diversions in and out of the Arkansas River <br />Basin upstream of the study site, no attempt was made to analyze <br />or study the diversions as was done for the Lake Creek Basin. <br /> <br />Knowing the flood flows at the gage site, the discharges were <br />transfered to the study area using the transfer equation from <br />TM-1. It should be noted that the Malta gage (07083700) which <br />lies 9 miles upstream of the study site was not analyzed due to <br />its extremely short period of record (8 years). <br /> <br />-5- <br />
