<br />EXECUTIVE SUMMARY <br /> <br />Seventy percent of the long-term annual suspended load of the White River near <br /> <br />Watson, Utah, is transported by discharges greater than 1,413 cfs. Flows greater than <br /> <br />about 1,413 cfs are also capable of scouring the bed of fine sediment. The effective <br /> <br />discharge of the stream is between 1,695 and 2,895 cfs. The White River is supply- <br /> <br />limited because more sediment is transported on the rising limb of the annual snowmelt <br /> <br />hydrograph than on the falling limb. Thus, higher flows are capable of transporting more <br /> <br />suspended load than they do. A channel-maintenance flow regime that guaranteed no <br /> <br />alteration to the natural flows greater than 1,413 cfs would prevent aggradation of fine <br /> <br />sediment on the bed, entrain gravels when flows approach bankful flow of3,708 cfs, and <br />ensure the availability of in-stream habitats. <br /> <br />Vlll <br />
