Much of the base flow of the river at <br />site 8 consists of irrigation return flows. In 1980, the U,S. <br />Soil conservation Service initiated a plan for on-farm control of <br />salinity that has reduced the annual quantity of salt discharged <br />to streams in the Uinta River basin by 30,000 tons most of that <br />reduction occurred in the Dushense River basin," <br /> <br />Figure 1, Trend Analysis of the salt loading of the <br />Duchense River near Randlett, Utah, <br /> <br />TONS (Tbousands) <br />800 <br /> <br />ACTUAl. 41-&0 <br /> <br />REGRESSION 01-&0 <br />600 + ACTUAl. &1-92 <br /> <br />REGRESSION &1-92 <br /> <br /> <br />'0 <br />III <br />o <br />,.;j 400 <br /> <br />.., <br />...... <br />III <br />CI) <br /> <br />200 <br /> <br />o <br />o <br /> <br />200 400 <br />Water <br /> <br />600 800 1000 <br />AC FT (Thousands) <br /> <br />1200 <br /> <br />1400 <br /> <br />D.UA FROId USGS <br />
