<br />above the confluence with West Tenmile Creek. The basin width is <br />7 miles and the total basin length is about 14 miles. The creek <br />slopes at about 1.4 percent at Frisco, 2 percent in the canyon, <br />and 2.7 percent in the upper basin. The elevations in the basin <br />range from 13,000 feet above Copper Mountain to 9,000 feet at <br />Lake Dillon. The study reaches within this basin are portions of <br />Tenmile Creek adjacent to and within the Town of Frisco. <br /> <br />The Meadow Creek Basin drains to the east from the Gore Range <br />into Dillon Reservoir at Frisco, just north of Lower Tenmile <br />Creek. The basin has a total drainage area of 5.8 square miles <br />and a length of 4.5 miles, The width of the basin varies from <br />1.0 tD 1.5 miles. The channel slope averages 1.7 percent fDr the <br />study reach near Frisco while steeper slopes of 10.7 percent <br />exist above Frisco in the Gore Range. The elevations in the <br />basin range from 12,700 feet to 9,000 feet at Dillon Reservoir. <br />The study reaches within this basin are portions of Meadow Creek <br />adjacent to the Town of FriscD, with some segments located within <br />the Town's corporate limits. <br /> <br />Miners Creek Basin is located to the east of Tenmile Range, with <br />the ridge to the east of Peak 4 being the southern boundary of <br />the basin. The basin has a drainage area of 6.8 square miles <br />which drains east into Miners Creek, then north to Dillon <br />Reservoir. Jug Creek and No Name Creek are tributaries of Miners <br />Creek. The study reach within the basin is a segment along <br />Miners Creek. <br /> <br />The Breckenridge Floodplain Information Report (Reference 8), <br />completed in 1975, derived frequency-discharge relationships for <br />certain tributaries within the Town of 8reckenridge. Synthetic <br />storms were derived from the statistical analysis of rainfall <br />data as presented in Technical Paper 40 of the U,S, Department of <br />Commerce, Weather Service. The peak flow rate data for French <br />Gulch and the Blue River (downstream of GDOSe Pasture Tarn) are <br />contained in the 1975 report, and provide peak flow rates for the <br />10-, 100-, and 500-year recurrence intervals, <br /> <br />The Hydrology Report for the Summit County Flood Insurance Study <br />completed in 1978 (Reference 6) contained the diSCharge-frequency <br />data that are tabulated in the published Flood Insurance Study. <br />Stream gage data for a particular study reach were statistically <br />analyzed to compute peak flow rates for specific recurrence <br />intervals, This was done for the Snake River using data from <br />Gage No. 475 and for Tenmile Creek using data from Gage No. 501, <br />Adjustments for locations other than at the gage station were <br />made by making a discharge versus drainage area comparison. <br /> <br />A regional regression analysis was performed to provide a basis <br />for estimating flows from ungaged drainage basins having similar <br />characteristics of gaged drainage basins. A single variable <br />(drainage area) algorithm was developed from the regression <br />analysis for each selected flood frequency. These algorithms <br />were converted into a graphical depiction (Reference 6) of <br /> <br />34 <br />
