BESTSM accounts for <br /> <br /> <br />monthly water volumes of inflows, diversions, return flows, river gains and losses, and outfiows for <br /> <br /> <br />each segment of the stream system and allocates water based on the Colorado water rights priority <br /> <br /> <br />system and other legal and institutional arrangements. <br /> <br />Water Yield for Reservoirs and Reservoir Combinations- Firm annual yields for the six <br /> <br /> <br />reservoirs selected and for the four representative combinations of reservoirs are presented in <br /> <br />Table S.1. The firm annual yield estimates were based on a projected high future-level of water <br /> <br />development in the basin with two different Green Mountain operating conditions. The first Green <br /> <br />Mountain Reservoir operating condition assumes that the Reservoir would continue to operate as <br /> <br /> <br />originally prescribed in Senate Document No. BO. The second condition assumes that the pumpback <br /> <br />system from Green Mountain Reservoir to Dillon Reservoir and the associated water exchange <br /> <br /> <br />arrangement would be in operation. <br /> <br />Some of the proposed reservoir sites are in effect alternative locations for regulating the <br /> <br />same water. When more than one reservoir is added in the upper portion of the basin, the yield of <br /> <br />the combination of reservoirs is less than the sum of the yields of individual reservoirs. <br /> <br />RESERVOIRS <br /> <br />Nine sites were initially designated as candidates for J9int-Use or Replacement Reservoirs. <br /> <br />Screening analyses reduced these to six dam sites. Dimensions of the six dams and reservoirs <br /> <br />c9nsidered in this reconnaissance.level study are presented in Table S.2. The study has involved <br /> <br /> <br />review of previous reports and published data, site investigations; hydrological analyses, preliminary <br /> <br />design and project cost estimates. <br /> <br />., <br /> <br />II <br /> <br />4 <br />
