The data report was published in 1994, An interpretative report <br />describing results of the study is currently in review and is scheduled for publication in 1995. <br /> <br />Based on preliminary data and results of the detailed study, the National Irrigation Water <br />Quality Program has decided that the Lower Gunnison Basin and Grand Valley will go into the <br />next study phase of the program, which is planning for mitigation. the east side of the <br />Uncompahgre Project and the lower Grand Valley will probably be the focus of the planning <br />effort, <br /> <br />Grand Valley Unit Monitoring <br /> <br />In a report released in 1993, the Inspector General (IG) of the Department of the Interior <br />stated that the Bureau of Reclamation has not adequately determined if the salinity control <br />projects have had an effect on salt concentrations and loads in the Colorado River. In 1994 an <br />investigation was initiated to determine the effects to salinity by salinity control projects in the <br />Grand Valley.'The objectives of the investigation are'to estimate salt loads and salt <br />concentrations for inflow and outflow stations for the Grand Valley Unit and to determine if <br />there are trends in salt concentrations and loads related to the Grand Valley Unit. Preliminary <br />evaluation of trends was completed in FY 1994, The analysis will be refined and a report <br />prepared in FY 1995, <br /> <br />. <br /> <br />Nevada <br /> <br />Salt Load Estimates from Public Lands <br /> <br />The project, conducted with Bureau of Land Management support, was described in detail in <br />the FY 1989 report to the Advisory Council, The primary objective of the project is to collect <br />hydrologic and water-quality information that will help identify source areas for saline <br />discharge and result in improved estimates of salt loading from public lands, Data are <br />published annually in the USGS Water Data Report for Nevada, <br /> <br />A report describing estimated water and salt budgets for the basins is in preparation, Data <br />from the stations mentioned previously and reconnaissance samples from ephemeral streams, <br />springs, 1l!id wells in the basins will be used in the report, <br /> <br />New Mexico <br /> <br />In addition to the activities related to the hydrologic data program (attachment 1), the New <br />Mexico District was involved with one interpretative study during fiscal year 1994: <br /> <br />. <br /> <br />IS <br />
