A sandy beach was present above and on the river right of the Charlie's Hole <br />structure before construction began. <br /> <br />The sandbar is created by the sediment load of Soda Creek shown flowing into the <br /> <br />Yampa River in Mr. McLaughlin's Figure 2, but that Creek and its sediment load are not <br /> <br />mentioned in his report. Also shown in Mr. McLaughlin's Figure 2 are the apparent <br />stream conditions directly upstream of Charlie's Hole. Note that these conditions, at a <br />relatively low flow, show accelerated current conditions that have created a readily <br />identifiable "wave train" indicative of accelerated flow conditions. Thus, Mr. <br />McLaughlin's own Pigurecontradicts his statements concerning decreased flow <br />velocities. These accelerated flow conditions would create increased riverbed shear <br />stress which would, in turn, increase the sediment transport capabilities of the streambed. <br />Also of note is the CWCB' s own survey shown as Attachments C, Fand G. in Mr. <br />Browning's letter of April 26, 2004. In these attachments there is no instance of <br />increased streambed elevation-indicative of sediment deposition-at or in the region of <br />the Charlie's or D-Holes when compared to a FEMA survey made before the Boating <br /> <br />15 <br />
