SECTtON 3 <br /> <br />RECOMMElIIlATIONS <br /> <br />1. It is necessal:Y to detemine the desired level of salinity control .which <br />should be implemented as soon as possible since this will~ictate the <br />typ.. anllaxtent of. lllSny of the &learnetives. This is especially the ease <br />for on-farm improVements. <br /> <br />2. Beeause on-farm improvements andletera1i linings are cost....ffeetive in <br />all of the irrigeted areas which ..,e.re exami~ed in this analysis, it is <br />reeommended'that the list o.fareas included in PL 93-320 be exp.anded. It <br />appears that. these basio on-farm improvements should be implemented in <br />all of the agrioultural areas as .tha initial .most .coat-effective salinity <br />oontrol program. <br /> <br />3. The Soil Conaervation Servica, the Extanaion Service end the other tech- <br />n:tcal ageneiaa involved in salinity contl:ol should make a long-tem <br />commitment of adequate technical aasist~nceto the growers. Th~on-going <br />work in the Grsnd Valley clearly . indicates the need for thist;!pe of .. . <br />program. It will baneceaaary to recru~t and specially train personnel <br />for this type of activity. <br /> <br />4. <br /> <br />On-farm improvement and lateral liningprogl:ams consistent with selected <br />levels of a basin-wide salin:tty control policy should be start:ed as soon <br />as poasible in all of the irrigated .areaa. <br /> <br />The Sublette Flats evaporation area and a network of barrier wells and a <br />minimal on-fam improvemantprogram should be initiated as the total <br />salinity control program fOT the Big Slindy ana in, Wyoming. <br /> <br />6. The use ofeenals and lateral. for winteT livest:ook._ter. shOUld be <br />. eliminated, if dependable altecrnative <tater supplies such as rUTal water <br />districts or groundwatercoulcl be. c1evelopecl. <br /> <br />5. <br /> <br />. . . <br />7. Design and construction of the by-passalternative for the.1?8radoxValley <br />'Sa~.t source should. begin ae soon a$p<>8si1:>le'. T"'edcf'l:tion,,.,.i;t: Ill'Iy...b..... <br />necessary to construct a series of small wells to intercept some of the <br />groundweter inflo.., to the salt c1ome-brine interface. <br /> <br />8. A salinity damage function is presentlY being developecl under contract to <br />the Water and Po..,,,r Resources Service. When this information becomes <br />available it is recommended that the feasibility of maintaining the 1972 <br />salinity concentration levels at Imperial Dam be re-evaluated. <br /> <br /> <br />10 <br /> <br />. <br />
