Fred and Sara Muller - O",ners of Holiday <br />~otel, Gunnison <br /> <br />It is our understanding that previous floodplain information <br />studies similar to this study have not been conducted in the study area. <br />A limited work in connection with the ice jamming problems 1n Gunnison <br />River was performed by the U.S. Corps of Engineers in cooperation with <br />tbe U.S. Bureau of Reclamation. <br /> <br />Ice jam problems have been reported to occur in the Gunnison <br />River above 1I1ueMesa Reaervoir. Iceformingintberiveriscarr1ed <br /> <br />downstream to the reservoir as slush. <br /> <br />As tbis slush reacbes the rcs- <br /> <br />ervoir's iced surface, it may produce ice jams that tould potentially <br />move upstream depending On the river conditions and tlimatological fac- <br />tara affecting such a development. <br /> <br />During the fatl of t971, the Corps of Engineers completed a <br />clearing and snag removal operation upstream of the Blue Meaa Reservoir <br />and construction of bigher banks along the river. Additional clearing <br />at the upstream end of Blue Mesa Reservoir and removal of the river <br />banks upstream through the Cooper Ranch and Neversink properties was <br />completed in the summer of 1971. <br /> <br />Hr.
