During wet years of no supplemental <br /> <br />irrigation requirement, much water would bo lost past tho state line. <br /> <br /> <br />In order to maintain a high rosorvoir uso factor, irrigation roquire- <br /> <br />ments must be increased during wet years by serving a large acreage~ <br /> <br />For this study, it is assumod that an additional <:Cl'eage would be <br /> <br />irrigated in ordor to accomplish maximum use of reservoir capacities <br /> <br />and water supply, In actual operation the Granada Reservoir wo~ld <br /> <br />make possiblo a systen of flexible irrigated aoroage bas~d on water <br /> <br />in storage in both Granada ani John ~brtin Reservoir at the begilU1ing <br /> <br />of tho irrication se(lson or SOl'lO other appropria"",e date" Thus, when <br /> <br />storage in John Martin RBservoir is low: Granada Reservoir wclte~ <br /> <br />. <br />
