Colorado-Utah state line is about.7 34 x 108 m3-E595,100 acre-feet/, . Taylor Draw Dam (Fig. 3) was completed in 1984, and is located in northwestern 'm'\\e 'fen 9b Colorado at approximately river kilometer (fkm)~, as measured upstream from the confluence with the Green River. Taylor Draw Reservoir has a storage volume of.l4 ClII e[!.~ e xl07 In3 (13,800 acre-feetr,-which is less than 3% of the total volume ofthe^annual streamflow. The dam i3' primarily operated as a run-of-the-river project where discharges 0(' splll Let released/rom the dam equal the inflow to the reservoir. The reservoir is used primarily for recreation and supplies little to no water for irrigation. Just downstream from the dam, the White River enters a broad alluvial valley. 15 I11lles For the next 2-:S-km, the river flows through a valley where bedrock outcrops on opposite 0.. 9 I,J. fIIlf15 . valley sides are between kS- andZkm apart. The river's slope is 0.0014 (Fig. 4) as it cuts a meandering course between outcrops of the Cretaceous Mancos Shale on the north, and the Tertiary Unita formation on the south. Several oxbow lakes occur on the flood plain in the upstream and downstream portions of this reach, and mid-channel islands are o\&-lVlile Co\ 0 rctclDJ spaced at approximately -l--JeB intervals. The town of Rangelr"is located at approximately the center of this reach. . . ("f't1 8', IS m"ile..s At approximately rkm 130, 25 km downstream from Taylor Draw Dam, the river cuts through the southwest flank of the Rangely anticline. The valley width narrows to I/t- 1/& mlle between 9-4and {).S kIn and the channel's increased gradient is 0.0030, which is 3 rYI t'le.s maintained for the next s-km. Between rlan 120 and 60, the river passes through a canyon cut into the Green River formation. Valley widths range from 0.15 to 0.6 kIn, and the overall slope is 0.0013. River gradient within this canyon is steepest between the Colorado state line and 7
