<br />" <br /> <br />aG5G <br /> <br />South Platte River flows considered available for storage in Narrows <br /> <br />Reservoir were, at times, of such magnitude that it would be physically <br /> <br />impossible to divert them without the construction of huge canals <br /> <br />which for long periods of time would not carry any water. With the <br /> <br />upstream storage at Narrows, the present canal systems would be used <br /> <br />for the diversion of the previously stored flood and surplus flows. <br /> <br />Because of these problems, new diversion facilities capable of diverting <br /> <br /> <br />up to 2,000 ft3/s would be required to accommodate the recharge plan. <br /> <br />Energy requirements for pumping the needed water for irrigating <br /> <br />37,000 acres of new land are significant particularly if center pivot <br /> <br />sprinkler systems are used. The energy consumption would amount to <br /> <br />about 19,500,000 kWh annually. <br /> <br />The basic conclusion in this analysis is that the present dynamic <br /> <br />equilibrium that exists between the ground-water system and the surface <br /> <br />water system on the Lower South Platte River should be maintained as is <br /> <br />and not altered by the development of a ground-water alternative to <br /> <br />the Narrows Unit. In other words, base flows in the South Platte <br /> <br />River shOuld not be reduced by increased purnpage of ground water <br /> <br />from the alluvial aquifer. <br /> <br />., <br /> <br />3 <br /> <br />-, <br /> <br />~ <br /> <br />~1t"1. <br /> <br />. <br />. <br />.' <br /> <br />. <br />I <br />I <br />i <br />,/ <br />i:' <br />I <br />I <br />: <br /> <br />\ <br />f <br />I <br />L <br /> <br />f-1"-. <br />. <br />r <br />\ <br /> <br />- <br /> <br />.' <br />
