It must be emphasized that the objective <br />of the Phase 1 investigation is to screen a relatively long list of alternatives and produce a short <br />list of alternatives which will be studied in greater detail in Phase 2. Where data and information <br />gaps exist, these gaps are noted and recommendations made for follow-up investigations in <br />Phase 2 for those alternatives not screened out during the Phase 1 investigation. Unless <br />i inapplicable to the specific alternative, the following topics are covered for each of the <br />I alternatives to the extent that existing data and information allows: <br /> <br /> . <br />, j . <br /> . <br />fe' <br /> I <br /> . <br /> . <br /> <br />Ii <br /> <br />. Description of the alternative: (1) project operation, (2) physical layout and location of <br />all project facilities, and (3) existence of channel flow capacity constraints affecting <br />project operation/feasibility. <br /> <br />. Source of water. <br /> <br />Necessary water rights and discussion of how these water rights will be obtained. <br /> <br />Total volume of water made available. <br /> <br />Feasibility of using water from this specific alternative to augment flows during the 7 to <br />I O-day peak spring runoff flow period. <br /> <br />Frequency/dependability with which the water can be delivered. <br /> <br />Feasibility of carrying over unused water from year-to-year. <br /> <br />. Capital and operation and maintenance costs. <br /> <br />. Potential effects of the specific alternative on yields from this and other existing projects, <br />i.e., would implementation of the specific alternative reduce the yield of other projects. <br /> <br />. Effect of alternative on this and other existing projects' operational flexibility or <br />reliability. <br /> <br />. Effect of alternative on this and other existing projects' operations and maintenance costs. <br /> <br />. Discussion of how the water available from this alternative will be administered during <br />the late summer and fall. <br /> <br />. Discussion of any potential legal problems other than water rights and permJttmg <br />concerns, such as rights of way, Colorado River Compact Problems, Blue River Decree <br />concerns, necessity of new Federal or state legislation, etc. <br /> <br />3-1 <br /> <br />p:\data\gen\Ocwcb\ 18 J 33\report\phase-1 \chap-3.doc <br />
