_� <br />6.0 IN-BASIN DEVELOPMENT PLAN FORMULATION AND EVALUATION <br />6.1 PIAN FORMULATION <br />IThe components retained after screening the alternatives discussed in the <br />I previous chapter are listed in Table 6.1. These components were combined into <br />six alternative development plans to meet projected in-basin water demands. <br />� The six plans were formulated with the intent of presenting a broad range of <br />development possibilities which would meet the target objectives to some <br />degree. These alternative plans are defined in general terms as follows: <br />� � <br />Alternative No. 1- a group of 17 recreational components. <br />Alternative No. 2- three storage reservoirs, one each in the Ohio Creek, <br />Tomichi Creek and Cochetopa Creek sub-basins. <br />I Alternative No. 3- a combination of alternatives 1 and 2. <br />Alternative No. 4- three storage reservoirs of Alternative 2 combined <br />I with ten recreation components selected from <br />Alternative No. 1. <br />Alternative No. 5- storage reservoirs on Tomichi Creek and Ohio Creek <br />� combined with the ten recreation components from <br />1 <br />Alternative No. 4 <br />I Alternative No. 6- one storage reservoir on Tomichi Creek combined with <br />ten recreation components from Alternative No. 4. <br />6.2 PLAN EYALUATION <br />The hydrologic computer model was used to evaluate the effects of <br />developing alternative plans. This allowed plans to be compared relative to <br />each other and also to the results of the No-Action Alternative discussed <br />previously in Chapter 4. <br />� The recreation components included in alternative plans do not consume <br />I water, although several of them may require management of streamflow through <br />I changes in reservoir release patterns. When modeling alternative plans, these <br />� <br />6-1 <br />� <br />
