<br /><:) <br />";&::a <br />;&::a <br />w <br /> <br />-19- <br /> <br />5. <br /> <br />The Sublette Flats evaporation area and a network of <br />barrier wells and a minimal on-farm improvement program <br />should be initiated as the total salinity control <br />program for the Big Sandy area in Wyoming. <br />The use of canals and laterals for winter livestock <br />water should be eliminated, if dependable alternative <br />water supplies such as rural water districts or ground- <br />water could be developed. <br />Design and construction of the by-pass alternative for <br />the Pa~adox Valley salt source should begin as soon as <br />possible. In addition, it may be necessary to con- <br />struct a series. of small wells to intercept some of the <br />groundwater inflow to the salt dome-brine interface. <br />A salinity damage function is presently being developed <br />under contract to the Water and Power Resources Service. <br />When this information becomes available it is recommended <br />that the feasibility of maintaining the 1972 salinity <br />concentration levels at Imperial Darn be re-evaluated. <br />Results of this analysis indicate the advisability of <br />implementing the identified most cost-effective salin- <br />ity control program regardless of where or which state <br />the salinity increases occurred. Colorado will contain <br />the major programs, and these projects will serve to <br />counter-balance salinity increases in other areas. <br />ivyoming could not physically be able to control its own <br />salinity increases. <br /> <br />6. <br /> <br />7. <br /> <br />8. <br /> <br />9. <br /> <br />I <br />I <br />I <br />, <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />'" <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />
