<br /><.~ <br />.1111 <br /> <br />Water will be used. in April only to prepare land for cul tiva- <br /> <br />tion or plowing when rainfall has been deficient. Growth will hardly <br /> <br />start before the middle of May and the prospect of later frost will <br /> <br />) <br /> <br />deter irrigation, when availability of stored water assures a late <br /> <br />season supply. During June and July the greater part of the irriga- <br /> <br />tion will be needed to mature a crop of alfalfa in each of these <br /> <br />months, as well as to water all the other crops. Sugar beets, pot a- <br /> <br />toes, and row crops generally will use considerable water in August <br /> <br />and even in September. Table 4 following presents the adopted use of <br /> <br />water, considering crops, climate and canal losses, on which data are <br /> <br />also presented in the table. <br /> <br />Table 4 <br /> <br />dtiilA <br />~~,:>I <br />',.'$.f <br /> <br />Use of Water <br /> <br />Month <br /> <br />:Temp-:Total :Irriga- : Canal: <br />: era-:water :Rain: tion : loss:Diversion:Diversion <br />:ture : re- :delivery: and : ~ <br />:quired: :in feet :waste: Feet of <br />of. : in ft.: Feet: Depth 1. annual <br />: depth depth <br /> <br />April 44 .10 .08: .02 65 .06 2 <br />May 52 .30 .06: .24 40 .40 13 <br />June 61 .63 .05: .58 33 .88 28 <br />July : 68 .62 .13 : .49 36 .76 24 <br />August 65 .50 .13: .37 40 .62 19 <br />September 58 .25 ;08: .17 50 .34 11 <br />October 47 .10 .07 : .03 65 .09 3 <br /> . . <br /> . . <br />Total :*2.50 :#.60: 1.90 40 3.15 100 <br /> <br />*Consumptive use of 2 feet in months of April to October, inclusive, <br />with allowance of .5-foot for deep percolation and unusable rain- <br />fall. <br /> <br />#Mean of low and average years. <br /> <br />,.,~:-:-;) <br /> <br />35 <br />
