<br />-9- <br /> <br />. <br /> <br />The permeability of these alluvial soils is very high and except for a <br />few very localized spots mainly near or within the golf course, the <br />potential infiltration is not influenced by a high groundwater table. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />III. HYDROLOGY <br />Hydrologic Records <br />Hydrologic records (from precipitation and streamflow gages) in the <br />mountainous areas of Colorado are of relatively good quality but have only <br />short tointerrnediate recording periods. Due to the extreme orographic <br />effects of the mountain barriers, however, the micro climate changes <br />so rapidly with elevation and from range to range that these records <br />must often be supplemented with detailed analyses. <br />Rainfall precipitation records are available from the National <br />Weather Service (NWS) for stations at Dillon, Eagle, Climax and Bond. <br />Short-term recordS have been kept by a CSU Atmospheric Science Department <br />research group administered by Lewis Q. Grant. Measurements have been <br />taken by the research group at sites between Leadville and Minturn and <br />at Vail Pass, four miles west of Vail Pass and two miles northwest of <br />Climax. <br /> <br />Snow precipitation records are taken at Shrine Pass and at Vail Pass <br />stations by the S.C.S., in addition to the Forest Service and Vail <br />Associates data at the Vail Ski Area site. Short-term snowfall records <br />were also collected along the highway by the C.S.U. research group. <br />Streamflow records are kept by the U.S. Geological Survey (U.S.G.S.) <br />for several of the streams within the Gore Creek catchment as well as in <br />nearby basins. Additionally, Short-term data is available from a study <br />for the Bureau of Reclamation on the meteorology of the Colorado River <br />basin. This study provides data on both storm ChJrJcteristics and rain- <br />f~l1 losses (illfiHration, detention anll evaporation). <br />
