Also. stredmflows d~ring the 1975 water <br /> <br />year were nearly equal to the long-term ~ean recoroed at many Upper <br /> <br />Coloraao River Basin gaging stations. <br /> <br />wnen oa i I Y va I ues were <br /> <br />unavailable. a linear-regression relation between dissolvea-sol iJS <br /> <br />concentration and water discnarge was calculated from the availaole <br /> <br />lo~-transformea data. <br /> <br />34 <br />
