ner•:1 for a reservoir of this s:Lze and the construction o` <br />Yamcolo as a first phase of developr.tent with the Bcar Reservoir <br />site held in reserve as a second ohase would minimize total <br />industrial ourla_y and at the sa*1e time neet the iririediate needs <br />of the valley. <br />Surface ;�7ater SunPlv <br />The sources o; water for irrigated lands in the oroject <br />area are the headwaters of the Xamoa Piver, Eqeria Creek and <br />King Creek. Eqeria and King Creeks flo�•� into Rock Creek and <br />thence directly into the Colorado River near ?�cCoy, Colorado. <br />The Yar,tpa F.iver flows into the �reen River in the extreme <br />*torthwest corner of Colorado. <br />F.geria Creek does not nrovide su`ricient sun�lies `or the <br />irrigable lands through ti�hich it £lows. Consequently, transbasin <br />diversions f.rom the Yar.ipa River are made by means of the Stillwater <br />Ditch and to a lesser exten*_ the Do�e Creek Ditch to auament these <br />flows. A najor part of the water stored in Stillwater Reservoir <br />is taken through the Still�•:ater Ditch for use on lands whose natur�sl <br />drainage is to F.geria Creek. <br />The watershed area for the above strear.is lies along the <br />East rim or the T.+7hite River Plateau. mhe highest point in <br />the drainage area is Flatton ?'!ountain having an elevation of <br />12,500 feet, and practically all of the contributorv drainage <br />area is between 10,000 and 11,500 feet. The maior portion of <br />the annual flow is contributed by snow melt runoff. Stream <br />flows normall�� vary from a?linir..ur,i in P�arch to a r.�axiriu*s in June. <br />A gaging station has been maintained by the U. S. Geological <br />Survey since 1952,on the Yampa River just above the point of diversion <br />of the Stillcaater Ditch. Average annual discharge at this gage for <br />22 �ears of record has been ?.�,900 acre feet from a drainage area <br />of 23 sauare miles. Dome CreeY, and Coal Creek enter the Yarmpa <br />a short distance below the gage. These two creeks have a combined <br />drainaqe area of 17..� sauare miles and are estimated to contribute <br />an average of 11,100 acre feet annually. Strean flows are shown <br />by month for the twent��-two vears of record in APPENDIX B. <br />The average floc-� in the three main Yamcolo Reservoir tributari_es, <br />Yamoa River, Coal Creek and Done Creek, are given in Table 14. <br />IV-10 <br />i ' <br />� ' <br />' <br />' <br />' <br />' <br />, <br />' <br />, <br />' <br />' <br />, <br />1 <br />LJ' <br />1 <br />1 <br />, <br />' <br />
