The steady-state water-table configuration for the proposed canal layout <br />'using all of the canals and stream channels is shown in figure 35. The parts <br />.of the stream that are shown at or above land surface represcnt those areas <br />where the simulated water table would rise above the bottom of the streambed <br />'and cause a flowing stream. The other areas where the water table would rise <br />'above the land surface represent waterlogged areas, The model did not account <br />,for additional evapotranspiration nor a change of seepage rates computed by <br />'the distribution model in any of these waterlogged areas, These need to be <br />accounted for in future analysis of this project as they will reduce the <br />waterlogged areas but they also will represent a loss of water to the system <br />.that agricultural interests would consider a nonbeneficial use. For instance, <br />evapotranspiration losses in the areas shown on figure 35 could be as much as <br />4 ft3/s, and this loss would probably reduce the flow in Beaver Creek <br />(table 12) by about 25 percent. The model computed that it would take <br />'57 years to reach steady-state with this recharge and pumping configuration, <br />:although from figure 36 it can be seen that the system nearly reaches <br />:equilibrium within 15 years, <br /> <br />92 <br /> <br />---------~--------- <br />
