<br />F1G.{ <br />~ <br />(nei:'l 1:~(C~ <br /> <br />'TABll I <br />,~~ <br />;n~.., herd <br /> <br />0110r} <br /> <br />Reservoir Pool at 4,404 Feet (1,342 Metres) <br /> <br />The water-table surface computed by the model for the proposed <br /> <br />reservoir pool at 4,404 ft (1,342 m) is shown on figure 4. The computed <br /> <br /> <br />loss to evapotranspiration was 26 ft3/s (0.74 m3/s). The rate of evapo- <br /> <br />:. <br /> <br />transpiration was the same as that for existing conditions because the <br /> <br />increase due to higher water levels was offset by the decrease due to <br /> <br />the area inundated by the proposed reservoir. Direct evaporation' from <br /> <br />the proposed reservoir was not modeled. <br /> <br />Ground-water discharge to the South Platte River was computed by <br /> <br />the model. A longer reach of Bijou Creek intercepted ground water than <br /> <br />for simulated existing conditions (compare fig. 2 and fig. 4). Computed <br /> <br />ground-water discharge to the South Platte River, including Bijou Creek, <br /> <br />is summarized in table 1. The net effect of the proposed reservoir on <br /> <br />ground-water discharge was to redistribute the discharge along the river <br /> <br />in the downstream direction. As shown in table 1, ground-water dis- <br /> <br />3 3 <br />charge decreased by 24 ft /s (0.68 m Is) above the proposed dam and <br />3 3 <br />increased by 24 ft /s (0.68 m Is) below the proposed dam. <br /> <br />.Jc> <br />
