<br />CJl p~ol, spills (as well as evaporation l~sses) have been deducted from the '~t9r
<br />availahle for storage" to arrive at so-called "amouc.ts of usable water." Colo-
<br />rado suggests that the calculated 190,000 acre feet of so-called "water avail-
<br />able f'or storage," if diminished by flood pool spills, might be said to repre-
<br />sent the streamflows available for storage, and, if further diminished by
<br />evaporation losses, to represent the water supplies availahle for release from
<br />storage, provided that such quantities, in both instances, be reoognized as be-
<br />ing e:tclusive of "Cad.doa flows heretofore used in Colorado," but inclusive of
<br />"Caddoa flOlvs heretofore used in Kansas," both of whioh are'~ 8.Vailo.ble for stor-
<br />age for purposes of regulation.

<br />15. Though included by Kansas in the so-called "water available for stor-
<br />age" and "amounts of usable water," the Caddoa flowsheretofore used in Kansas
<br />were ignored, or not estimated, in the doc~ent submitted for study and dis-
<br />cussion. To arrive at the amouD!; s of "new water" attributable to Caddoa reser-
<br />voir operations, under the plan of operation assumed by Kansas. the Caddoa
<br />flows heretofore used in Kansas must be calculated or estimated. Total State-
<br />line flows. averaging 260,700 acre feet annually, were segregated by Kanzas:
<br />190,000 acre feet, or 73%, river flow passing Caddoa, and 70,700 acre f'eet, or
<br />27%, net accretions below Lamar. Total uses of State line flows in Kansas are
<br />indicated by the differenoe between 260,700 acre feet passing the Stateline
<br />and 171,000 acre feet passing Garden City, - a difference of 89,700 acre feet.
<br />which includes ditch diversions, estimated at 84,'00 acre feet, as well as
<br />channel oonveyance losses and river water used from wells by pumping. Segre-
<br />gating the uses in Kansas in the same proportions in which S'l:ate line , flows were
<br />segregated by Ke.nsas,the 89,700 acre feet of total use would consist of 24.200
<br />acre feet from net accretions belo"", Lemar, and 65,500 acre feet from rrver flow
<br />passing Caddoa.
<br />
<br />16. To arrive at amounts of so-called "new water." the Caddoa flows here-
<br />tofore used in Kansas must be deduoted from the so-called "amounts of usable
<br />water." as follows:

<br />".Amounts of Usable Water" 121.000 137.000 153.000

<br />used in Ke.n&O.s" 65.500 65,500 65,500
<br />Estimated Amounts of So-
<br />called "New \'Iater" 55.500 71,500 ' 87,500

<br />17. The showings of Studios 3 and 4, as compared with Study 2, as sum-
<br />marized by Kansa.s, are to the effect that greater "demnnds on the reservoir,"
<br />or greater assumed releases from storage, will have the effect of reducing
<br />losses of water from the reservoir by evaporation and spill (0. result ~\ich is
<br />evident and admitted). and will thereby inorease the "amounts of' usable _ter," .
<br />a conclusion questioned by Colorado depending on what is mBant ~J "usable
<br />~water. II __ On theother~ hand,- the graphs and other tahula tions submitted by ~Kansas
<br />tend to show that grenter assumed releases fraa storage are, also accompanied by
<br />smaller average volumes of water in storage, and by periods of greater frequen~y
