j~ j . /e present hopeful outlook toward full agreement being reached 'within thetlextfew'years, full conservation use of the Navajo Reservoir 'Will be needed at an earlier date than he,retofore assumed. For this' reason it is' recommended that the Navajo' Dam and Reservoir 'be eliminated as a unit of the storage project, and that itbeoomea part of the Shiprock Indian Irrigation Project, with portions ,of its, cost,along"with por- tiOlis of the costs of other joint facllities,tobe che.rgedlater against the potential South San Juan and San Juan-ChamaProjects. ' It should, be the first unit of the Shfprock Project to be constructed. In view of the close relationship between the South, San Juan and ShiprookDevelop- ments, it ia believed' to be appropriate to' incorporate them as one project, to be called the Navajo Project, consistillg of two divisions, the Shiprook (Indian) Division and tile Soutll San Juan Division. Tile NavajO Reservoir is, recommended hereininitia1ly as apart of the Shiprcick Division as it is an elisentialintegral part of the Indian ' DevEllopment without which the program tOlllake the Navajo Indisn self. sufficient cannot be fully carried out. , 15. ' After reviewing the proposed report thll state of colorado ' recol1llllended that the Whitewater Unit 'on the Gunnison River not be,in~ eluded as an initilil unit of the Colorado River storage Project .AI~ though desiring one of the initial units to be located on the Gunnison River, the state at that time had not decided Which of the sevllral possible units should be selected, and ,recol1llllendedthat certain 'further ' ' studies be made of the' Gunnison RiVer Units before 'final selection is made. Further study was given' by the Bureau of, Reclaination to the loca- tion of storage units on the Gunnison River, in accordance witnthis recol1llllendation, and information was made IlNlillable to the State. The Director of the'Colorado Water Conservation Board'has recently advised us that the Board has approved' a reservoir atthiil CUrecanti site wi th a storage capacity of 940 ,000 acre-feet :, andhae urged that this project be included as a part of the initial authoril/:ationoftheColorado River Stor~ge Project.. Analyees of the'Colorado River Storage Project with both the large Curecanti (2,500,000 acre-feet)' and the small Curecanti (940,000 ac::re-feet) are includEld' as attachments to thiS1'eport.
