<br />Model-simulated historical monthly streamflows for control point 28 (Yampa <br />River at Craig, Colo.) are presented in tables 22 through 26. This control point <br />is located downstream from the proposed Craig Reservoir and also downstream from <br />the confluence of the Williams Fork (fig. 1). The simulated results for reservoir- <br />development option 1 represent both limited upstream reservoir development (ta- <br />ble 3) and major downstream diversions from Juniper and Cross Mountain Reservoirs. <br />The option-2 simulations included a larger number of upstream reservoirs (table 3) <br />and consequently further reduced the flow at this site. Monthly streamflow simula- <br />tions for reservoir-development options 3 and 4 included the immediate upstream <br />effects of the Craig Reservoir and tended to even out the monthly flow distribu- <br />tion (tables 22 through 26). The monthly streamflow for reservoir-development op- <br />tion 4 is less than for option 3 because of the absence of the downstream demand <br />from Juniper and Cross Mountain Reservoirs. The simulated historical 50-year mean <br />monthly streamflows for the 100-percent water-use allocation (table 26) could be <br />reduced to zero for at least 4 months each year under options 3 and 4. <br /> <br />Table 22.--Summary of simulated historical. monthl.y streamflows~ <br />control. point 15 (Yampa River at craig~ Colo.)~ <br />for historical conditions and with 100 percent of transmountain diversions <br /> <br />[FLOW VALUES: A=MEAN; B=MEDIAN; and C=80-PERCENT EXCEEDENCE.
