The irrigation water demand is based on the ALP Definite Plan Report which made a thorough <br /> study of the weather data to estimate crop consumptive use,which is listed below in Table 1. <br /> Table 1 <br /> Irrigation Consumptive Use <br /> (From ALP Definite Plan Report) <br /> Month C.U. (in feet) <br /> April 0.05 <br /> May 0.16 <br /> June 0.43 <br /> July 0.51 <br /> Aug 0.42 <br /> Sept 0.30 <br /> Oct 0.10 <br /> Total 1.97 <br /> The irrigation demand is determined by applying a conveyance and application efficiency to the <br /> above monthly consumptive use values. 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 /> Table 2 <br /> Irrigation Water Requirement for A Full Water Supply <br /> Month Gravity Sprinkler Total <br /> Delivery Eff. 40% 70% n/a <br /> Acres 500 ac 640 ac 1,140 ac <br /> April 62 AF 46 AF 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 /> 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 /> 11 <br />
