<br />[ <br /> <br />Lining <br /> <br />Concrete line all canals and laterals justifiable with salinity control <br />funding in study area. <br /> <br />Concrete line adobe area canals and laterals. <br /> <br />Concrete line all deteriorated sections of canals and laterals. <br /> <br />Plastic line all canals and laterals justifiable with salinity control <br />funding. <br /> <br />Earth line all canals and laterals justifiable with salinity control <br />funds. <br /> <br />Land retirement <br /> <br />Retire 12,000 acre of nonarable irrigated land; concrete line all canals <br />and laterals. <br /> <br />Retire 12,200 acres of nonarable land; concrete line deteriorated sections <br />of canals and laterals. <br /> <br />Retire 12,000 acres of nonarable irrigated land; concrete line all <br />deteriorated sections of the east side of the Uncompahgre River. <br /> <br />Retire an a,OOO-acre block of land in the northeast part of the study area; <br />line all deteriorated sections of canals and laterals in the study area. <br /> <br />Retire 12,000 acres of nonarable irrigated land; no improvement. <br /> <br />Other <br /> <br />Sprinkler irrigate 70 percent of the study area; line all canals with <br />concrete and install pipe in all laterals. <br /> <br />"Futu re without" condition. (This alternat i ve is based on the as sumption <br />that no acceptable construction alternatives can be developed; however, <br />due to operation, maintenance, and rep lacement and rehabi litat ion and <br />betterment programs, and irrigation management, some salinity reduction would <br />be accomplished.) <br /> <br />Candidate Plans <br /> <br />Seven candidate plans were selected from this list on the basis of <br />public input, technical and economic criteria, and practicality of <br />implementation. The candidate plans for the Lower Gunnison Basin Unit <br />are as follows: <br /> <br />Plan A-I Concrete line 514 miles of the West, Montrose and Delta, and <br />Ironstone Canal systems on the west side of the Uncompahgre <br />Valley, and the South, Loutzenhizer, Selig, East, and Garnet <br />Canal systems on the east side of the valley.
