Given a <br />potential consumptive use rate of 2.18 acre-feet per acre, the average annual <br />shortfall in the ditch supply was only about 127 acre-feet or about four percent <br />of the irrigation water requirement. <br /> <br />The results of the analysis of the Broyles wells indicated an average annual <br />stream depletion of 1,205 acre-feet. This amount is essentually the irrigation <br />requirements for the extra 500 acres irrigated under the ditch, combined with <br />the minor shortfall in the ditch supply. Based on the minimum interpretation <br />of the well water rights, the wells were capable of pumping at more than 5,600 <br />acre-feet per year, or almost five times the calculated stream depletion. <br /> <br />The separate analyses of the Keesee Ditch and Broyles wells irrigation <br />operations has demonstrated the adequacy of each source to supply the respective <br />assigned acreages. The annual and monthly pattern of diversions for the Keesee <br />Ditch do not exhibit any apparent reductions or changes in use as a result of <br />the operations of the Broyles wells. The pattern of operation and calculated <br />effects on the Arkansas can therefore be considered separately from the effects <br />of the Broyles wells. By limiting the analysis of the Keesee Ditch to the decreed <br />1,400 acres, the resulting historical depletions can be used as the basis for the <br />change of Water rights. <br /> <br />t/~ <br />{Je.9 r I.u)~' ~ <br />e-< 1.p j 0 <br />s v> fc 0 +lY'I'-'\'\ ~ <br />\ \0 ~ .p<V ,.e, Ie <br />k1eQO /t"Y' f -vI' ad <br />/' _,,~;:', ":") C ,1M j,~Je 'I,1,c, <br />~IP'C ,.,,,r' ,.Pj 1#1 \ .cP'. <br />L.- e J/ f"M . 1.: CO' Y (/ ~V- <j>- 1 <br />()J I c1\.t 1 "e5 .;t<' ~!rJ. <br />,;_~..I, /'I,,(..f \ (}wi- J'"" :' <br />.'~ ~_ I .....
