<br />33 <br /> <br />Divide the acreage into three classes of 200,000 acres each. Allot, on <br /> <br />January l of each year, l.OO acre-feet per acre to the first priority acreage, <br /> <br />and 0.50 and 0.25 acre-feet to the other two priorities; this would total 350,000 <br /> <br />acre-feet. Then allot the balance of water in storage on January l to all acres <br /> <br />on an equal basis. Each month thereafter allot the new water on an equal basis <br /> <br />to all acres; when one class has received 2.50 acre-feet it no longer would be <br /> <br />given an allotment until after the next December 3l; the new water would be equally <br /> <br />divided each month among the remaining classes. If all 600,000 acres gets the <br /> <br />2.50 acre-feet limit, the.additional water would be held in storage. <br /> <br />Table 22 (p. 34) illustrates operation under above plan, for period 1945-64. <br /> <br />The minimum allocations, in acre-feet per year would be: <br /> <br />First <br />200,000 acres <br /> <br />Seconcl <br />200,000 acres <br /> <br />Third <br />200,000 acres <br /> <br />MiniInum year................. <br />Minimum 3-years.............. <br />MiniInum 5-years.............. <br />Aver~e for 20 years......... <br /> <br />0.98 <br />lo25 <br />lo75 <br />2.l5 <br /> <br />0.48 <br />.75 <br />lo37 <br />lo90 <br /> <br />0.23 <br />.50 <br />lol7 <br />lo78 <br /> <br />Another scheme may be illustrated by assuming water limited to 2.50 acre-feet <br /> <br />per acre per year on 600,000 acres, with six priorities of lOO,OOO acres each. <br /> <br />Assume that the water to be allocated will be divided into 7.5 equal parts and <br /> <br />that priority l will get l.5 parts; priority 2, l.4 parts; priority 3, l.3 parts; <br /> <br />priority 4, l.2 parts; priority 5, l.l parts; and priority 6, l.O part. The annual <br /> <br />allocation received by different priorities for annual supplies varying from 350,000 <br /> <br />to l,500,000 acre-feet are shown in table 23 (p.34); data from this table were <br /> <br />plottea to define curves of figure II (p. 48). These curves show the allotment <br /> <br />for any supply likely to be available. It ma;y- be noted that when the supply exceeds <br /> <br />l,500,000 acre-feet all acres will get the 2.50 acre-foot limit. <br /> <br />The above illustration is based on annual figures, but in practice allocations <br /> <br />should be made monthly. Table 24 (p.35) shows how monthly allocations could be <br /> <br />made, based on records for the 1963 calendar year. In the table, the inflow sh0'cn <br /> <br />0':':2:. J <br />
