a -4- r '. ~ - - - ---- - ----------- ----- ""-1 flow). Sinc~ tJ:e total Stateline flow avers_ged 260,700 acr-e f'eet annually, ~and since Kansas olassifies 190,000 aore feet thereof as coming from Caddoa, the remaining 70,700 acre feet was assumed to have originated below ~addoa. Expressed another way, the Kansas procedure indioates that the 190,000 acre feet of Stateline flow, oalculated to have :;assed leJ:1ar, was e.ssUllled to have passed Caddoa, and to have been "available for storage" in ~addoa reservoir. r ,-e 'e --- , -, 8. The few exceptions to the general rule above mentioned appear to have resulted from substitutions by Kansas of aSBUII1ed ge.inB~'between lamar and Stateline, in several ~onths of the study period (usually at times of ma- jor floods) When the records themselves disolose losses. The effect of such adjustments, amounting to ,changes in official records may be illustrated by comparing the 190,000 acre feet calculated by Kansas. with the 193.600 acre feet annually recorded at Lamar. Such a difference. amounting to 3.600 acre feet, or less than 2 percent, is relatively small, and at this time _y be ignored. 9. While the terms "available for store.ge" and "amourJ; s of usable water". are not denned in the document under discussi on, it is apparent from an an"ly- sis of the calculation procedure followed by K",sas, as herein later more fully discussed, that the 190.000 acre feet of Caddo a flow considered "aVlli lable for' store,ge" is excl',lsive of quantities hBrein termed "Caddoa flows heretofore U3 ed in Color"do " but inoludes streamflows in some months in excess of avail- able and effective storage capaoity in the assumed completed irrigation pool. and includes the calculated "amounts of usable water," - oaloulated by de- duoting evaporation losses and flood pool spills from the 190.000 aore feet considered "available for storage;" and that the calculated "lU:lounts of.usable' _tel'," in turn. include quantities herein 1c:;rmeqc"Caddoa, f~.ows~her!":tot:or\l ._~ used in Kansas," as well as "new water," - ~e-f.if.1':t~!!~ ~-W- attri- butable to operations of Caddoa reservoir. whioh segregations of the calou- lated "amounts of usable water" 'MIre not IIlll.de in the document under discussion. but are necessary to an understanding of the quanti ties of water therein re- ported. 10. The plan of reservoir operation assumed by Kansas. while unexplained. appears to consider "Caddoa f'lCl'l's her!3'tofore used in Colorado" as unavailable for storage, whereas "Caddoa flows heretofore used in- Kansas" are treated as "available for storage," - which raises a question as to how the irrigation pool in Caddo a reservoir shall be operated, and what are its purposes as au- thorized by Congress? Exolusive of the primary purpose of flood oontrol, aO- complished by storage of water in the flood pool, at times of major floods and abnormal streamflows.the irrigation pool was autr~rized for "streamflow regula- tion e-Ild water oonservation" for the benent of irrigation interests in Colo- rado and Kansas. Both .....streamfloVl regulat10op' and water conservation....... require, and may be aocomplished only by the storage of water in the irrigation pool. - _tel' oonservation by the storage of streamf'lovrs heretofore unused and wasted. to make them water supplies available for additional diversion and increased use in the two States; and streamf'low regulation by the storage of 6"treamflows heretofore appropriated, diverted and used, to make them available when and as needed by lands and crops. rather than_when they occurred ~nder pre~Caddoa__~___ conditions. - - - .......,
