<br />. <br /> <br />. <br /> <br />13G~ <br /> <br />Colorado River Basin vlater Quality Control Project, and, with the <br />U. 3. Bureau of Reclamation, has identified e number of specific <br />salinity control ~rojects. A reconnaissance level investi~ation has <br />been made of these pro~ects. These salinity control projects are <br />based upon the improvement of existine irrigation projects to reduce <br />~~e quantities of salts entering the river system and the elimination <br />of saltE from llieh1y saline natural springs or river beds. <br />Althoueh these studies were essentially completed approximately <br />two years aro, the comprehensive report, which includes the results <br />of these stu~ies, has not yet been issued. However, information on <br />these salinity control projects is available from the files of the <br />federal agencies and in the reports of the Type I, Comprehensive <br />Framework Studies for the Upper and Lower Colorado Regions. These <br />reports are as yet unpublished in a final eoition. <br />Twelve irrigated areas and four natural sources of mineral pol- <br />lution have been identified that appear susceptible of control and <br />appear to be particularly promising at this time. The locations of <br />these projects are shown on Figure~. It should be noted that there <br />may be other salinity control projects that have not been identified <br />to date that will be proven feasible in ~he future. For e:tample, <br />five flowing ~ells that together discharged 100,000 tons of salt <br />annually to the river were recently plugged at very low cost, and <br />corrective actions on other such sources may be accomplished in the <br />future. <br />The t\lelve projects involving drainage from irrigated areas vary <br />in size from 100,000 acres in the Uncompahgre Valley of Colorado to <br /> <br />-10- <br />
