<br />I. <br /> <br />. ~ <br />v <br /> <br />1HE PROBLEM <br /> <br />The Colorado River Basin (Basin) <br />encompasses portions of seven <br />states. The river flows over <br />1,400 miles from its headwaters in <br />Colorado to its terminus in the Gulf <br />of California in the Republic of <br />Mexico. On its journey, it joins with <br />tributaries from Wyoming.. Utah, <br />and New Mexico; flows through the <br />Grand Canyon; and provides state <br />')undarics for Nevada, Arizona, <br />.nct California. <br /> <br />The river's water, now and in <br />future years, has been fully <br />allocated. through a long history of <br />appropriations and negotiations <br />that include acts, compacts, decrees, <br />and an international treaty, known <br />collectively as The LAw of the River. <br /> <br />About half of the present salinity <br />concentration in the Colorado River <br />at Hoover Dam ncaT Las Vegas, <br />Nevada, is attributed to natural <br />sources. The remaining half is <br />man-induced as indicated in <br />figure 1. <br /> <br />Natural Sources 47% <br /> <br /> <br />Exports 3% <br /> <br />Irrigation 37% <br /> <br />Figure 1. - Salt loading sources. <br /> <br />Municipal and <br />Industrial 1 % <br /> <br />Reservoir <br />Evaporation 12% <br />
