typically the same at both gaging stations. Flood magnitudes at Myton prior to 1920 <br />were significantly larger than those after 1930. <br />METHODS <br />Archival searches, geomorphic field measurements, aerial photo interpretation, <br />and U.S. Geological Survey gaging station record analysis were conducted in this project. <br />Initial archival searches were conducted at numerous libraries, government agencies, <br />and local agency offices in the Uinta Basin (Table 1). Field work, conducted from <br />October to December 1995, consisted of channel width measurements and longitudinal <br />surveys of geomorphic features. Comparisons of channel planform change and analysis <br />of gaging station records at two Geological Survey gaging stations -- Duchesne River at <br />Myton (station 09295000) and Duchesne River near Randlett (station 09302000) -- <br />were completed in the office. <br />Archival searches yielded descriptions of channel conditions between 1875 and <br />t 936. The primary sources were newspaper articles and persona! interviews. Changes <br />in channe( planform were assessed using original plait maps and accompanying field <br />notes from the U.S. General Land Office Survey and 1936 aerial photographs. The platt <br />maps were obtained from the U.S. Bureau of Indian Affairs at Fora Duchesne and the U.S. <br />Bureau of Land Management state office in Salt Lake City, UT. Platt maps show channel <br />planform in relation to the surveyed township and range system (Fig. 5), and survey <br />notes describe the location and width of the channel along quarter-section lines. The <br />maps and notes consist of surveys conducted in three different years, 1875, 1882, and <br />1903, but no one survey includes the entire study reach. Data from each survey were <br />compiled to form one integrated map of channel conditions for the period prior to <br />16 <br />
