<br />EXECUTIVE SUMMARY <br /> <br />Seventy percent of the long-term annual suspended load of the White River near <br />c.~ <br />Watson, Utah, is transported by discharges greater than 40 m3/s. Flows greater than <br /> <br />about 40 m:Ls are also capable of scouring the bed of fme sediment. The effective <br /> <br />discharge of the stream 1S between ~ and_~3jP?ls. The White River is supply-limite~ <br /> <br />because more sediment is transported on the rising limb of the annual snowmelt <br /> <br />hydro graph 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 40 m3/s would prevent aggradation of fine <br />~ <br />sediment on the bed, entrain gravels when flows approach bankful flow of 1 05 m~, and <br /> <br />ensure the availability of in-stream habitats. <br /> <br />Vlll <br />
