Since about 640 acres are sprinkler irrigated and 500 <br />acres are gravity irrigated, the delivery demand at the reservoir must be estimated for each type <br />of irrigation. Table 2 shows the estimated irrigation demand for each type of irrigation for each <br />month in acre-feet. <br /> <br />Table 2 <br />Irrigation Water Requirement for A Full Water Supply <br /> <br />Month Gravitv Sprinkler Total <br />Delivery Eft. 40% 70% n/a <br />Acres 500 ac 640 ac 1 ,140 ac <br />April 62AF 46AF 108 AF <br />May 200 AF 146 AF 346 AF <br />June 538 AF 394 AF 932 AF <br />July 638 AF 466 AF 1 ,104 AF <br />Aug 525 AF 384 AF 909 AF <br />Sept 375 AF 274 AF 649 AF <br />Oct 125 AF 91 AF 216 AF <br /> --------- --------- --------- <br /> --------- --------- --------- <br />Total 2,463 AF 1 ,126 AF 4,264 AF <br />AF/Ac 4.93 2.81 3.74 <br />Note: AF is acre-feet <br /> <br />11 <br />
