<br />Introduction <br /> <br /> <br />I-" <br />W <br />~ <br />oJ:>. <br /> <br />The Department of the Interior and the United <br />States Department of Agriculture, in cooperation <br />with the Colorado River Basin Salinity Control <br />Forum (Forum) work group, reaSlessed the <br />adequacy of the Colorado River salinity control <br />program in meeting numeric criteria for salinity <br />at three stations (Hoover, Parker, and Imperial <br />Dams) along the river. The salinity control <br />program was authorized in the Colorado River <br />Basin Salinity Control Act of 1974 (Public Law <br />93.320) and amended by Public Law 98-569. <br /> <br />This joint evaluation report outlines the <br />coordination efforts to effectively undertake the <br />salinity control program, it describes the <br /> <br />lJ1>H <br /> <br />IEWlf\ <br /> <br />\~ <br /> <br />La YlQas wasn <br /> <br />CAlF. <br /> <br />\ <br /> <br />assumptions and methods used to arrive at the <br />current salinity control program-the 1990 <br />implementation plan, and it summarizes the <br />salinity control program and its effects. <br /> <br />The report also describes major program <br />activities through fiscal year 1990. Salinity <br />control units needed to achieve the objectives of <br />Public Law 93-320 and Public Law 98-569 are <br />shown in figure 1. This evaluation, updated <br />annually, monitors the program implementation <br />schedule, allowing inclusion of newly <br />formulated, more cost-effective units and <br />changes in technology. <br /> <br />W'ItlWG <br /> <br />~.-..a._CfMk <br /> <br />Son.... _ <br /> <br />" <br /> <br />foEW <br />>.et <br /> <br />Salinity Canlnll UnrtB <br />.
