<br /> <br /> <br />o <br />'::.' <br />" ) <br />00 <br />e..n <br />...... <br /> <br />SUMMARY (Continued) <br /> <br />plan. This plan is described in detail and then is :followed by alterna- <br />tive plans that re:flect emPhasis on di:fferent uses for the available water <br />supplies and resources. The al ternati ve plans are identif'ied as: <br /> <br />1. States' alternative to the :framework plan (6.545 million acre- <br />:foot) level o:f development, <br /> <br />2. States' alternative at the 8.16 million acre-:foot level of <br />development, and <br /> <br />3. States' alternative for water supply physically available at <br />site in the region' (9.44 million acre-feet). <br /> <br />Comparisons of the framework plan and alternate levels of development <br />are shown in the table on the :following page. <br /> <br />The proposed levels of development meet the requirements o:f OBERS <br />projections and use the available resources of the region in varying de~ <br />grees. Water in the region, as in all semiarid areas, is the limiting <br />criterion. However, it appears that the commitments of the Colorado River <br />Compact can be met and, except :for some water deficiency for fish and wild- <br />life uses in Arizona and New Mexico and local shortages during low stream- <br />flows, on-site demands can be met :for the 6.5 MAF development level. At <br />higher levels, augmentation will be required. <br /> <br />Costs have been estimated only for the framework plan. Installation <br />and annual operation, maintenance, and replacement (OM&R) costs for water <br />related and associated development for the 1966-80, 1981-2000, and 2001- <br />2020 time frames are shown in the following tabulation: <br /> <br />Development costs for"~ramework plan <br />($1,000).Y <br /> <br /> Water Associated Total <br /> development development development <br />Installation <br />1966-1980 . 1,190,300 2,700,840 3,891,140 <br />1981-2000 1,074,350 5,982,310 7,056,660 <br />2001-2020 658,780 1,397,680 2,056,460 <br />Annual OM&R (change <br />by end of period) <br />1966-1980 17 ; 540 215,950 233,490 <br />1981-2000 20,290 452,780 473,070 <br />2001-2020 9,440 (-)21,720 (-)12,280 <br />lJ A Federal-nan-Federal breakdown is included in the section on <br />costs. <br /> <br />ii <br />
