Between 19'14 and 1980, th~(!)SGtestablished baseline discharge and water quality data in anticipation of widespread oil shale extraction in the region (Lindskov and Kimbal!\984). Suspended sediment transport measurements at the Watson gage were made on a daily basis for most of water year 1975, and these data are used in this study. Bedload transport was estimated from observed changes in mean channel depth during high flows at a gage temporarily located near the mouth of the White River (station " cts 09306900) (Seiler and Tooley/1982). During a flood of 116 m3/s}he bed scoured roughly 1 m at this site. They estimated that approximately 1.3 x 106 m3 of bed material f'fn was scoured and filled in 29 km upstream from the gage during this flood. Jurado and Fields (1978) used airphotos taken as early as 1936 to document long-term changes in channel position throughout the White River. They found that the White River is prone to channel migrations, and that the degree of channel migration is dependent on specific reach characteristics such as slope and degree of bedrock confinement. During the past century, the channel has migrated less in reaches of high slope and narrow bedrock confinement.
