<br />USU Projects: <br /> <br />A research program was developed to integrate geomorphology and <br />ecological sampling in Desolation and Gray Canyons, a debris flow- <br />affected reach of the Green River. Research activities in 1994 focused <br />on development of a geo-referenced data base of the distribution of <br />river-deposited sediment and associated low velocity habitat in these <br />canyons. We also developed a geomorphic data base with which to <br />characterize the availability of nursery habitat in these canyons at <br />different discharges. <br /> <br />Our research activities were restricted to air photo and map <br />interpretation during 1994, and only limited funds were expended. <br />However, our data base will permit detailed field characterization of <br />habitat/geomorphology relations during 1995 field season. <br /> <br />Relative to alluvial sections of the Green River, low velocity habitat <br />is less abundant in Desolation and Gray Canyons. However, at bankfull <br />flood stage, there is more available habitat in Desolation than Gray in <br />downstream fixed meandering reaches of Labyrinth and Stillwater <br />Canyons. Thus, we can consider these canyons as always having a <br />relatively constant amount of habitat available, while adjacent <br />alluvial reaches change in habitat availability more widely between low <br />and high discharge. <br /> <br />The appended three GIS mapped reaches .and graphs indicate results of <br />this project. <br /> <br />VII.
