<br />. . <br /> <br />YAMPA RIVER <br /> <br />Box Elder Site - 9/25/84 <br /> <br />Air photos - no noticeable changes in channel morphology between <br />1951 photos and 1982 photos. Noticeable side canyon input at <br />Warm Springs (1965). Bars and vegetation appear to have been <br />stable over Photo span with loss of minor bar at mouth of Yampa. <br />Flow width measurements may be difficult due to deep canyons and <br />extensive shadows. Plotted cross sections Show very little <br />change in bottom elevation between flows. LongitUdinal profiles <br />Should be plotted for different flows. <br /> <br />Conclusion: Suitable site for PHABSIM. <br /> <br />\ <br /> <br />Cleopatra's Couch and Replicate Site (Spawning Site) - 9/25/84 <br /> <br />Air photos - ve~ minor indications of more numerous bars <br />(midchannel) on 1961 air photos relative ~o 1982 photos in reaCh <br />approximately 1.5 miles downstream of Cleopatra's COUCh reach. <br />Cross section plotting has not been done for differing flow <br />conditions and should be completed. Also, longitudinal profiles <br />need tO'be plotted and compared for differing flows. <br /> <br />Conclusion: Channel stability is assumed. <br />
