<br />geochemical information for evaluation of surface and ground <br /> <br />water systems as well as for management and policy decisions. <br />!\) <br />CJl To provide information required by the federal, state, <br />oj:>. <br />c..., and local agencies to address Colorado River water quantity <br /> <br />and quality problems, the Water Resources Division operates <br /> <br />and maintains a network of about 600 stream gaging stations <br />and 175 quality stations in the Colorado River drainage <br />basin. Streamflow and water-quality information from these <br />stations provide input to the hydrologic data base for <br /> <br />Reclamation's Colorado River Simulation System. <br /> <br />In addition to cOllecting hydrologic data, the Water <br /> <br />Resources Division conducts specific studies on surface <br /> <br />water, ground water, and water quality. During the past <br /> <br />year, Division scientists completed a major study of salinity <br /> <br />in the Colorado River system. <br /> <br />Results of this research <br /> <br />include a statistical analysis of streamflow and dissolved <br />solids data for all gaging stations in the Upper Colorado <br />River Basin with more than 5 years of record. Significant <br />long-term trends in dissolved solids concentration and salt <br /> <br />load were found associated with reservoir development, <br /> <br />mining, salinity control and changing irrigation practices. <br /> <br />Salt loading in Las vegas Wash, Nevada is also being studied. <br />The purpose of this investigation is to determine whether the <br />proposed engineering plan intended to reduce salt loading to <br />the Wash near Henderson is feasible and cost effective. <br /> <br />-18- <br />
