"">",,,'-/1' ,:,.::, , ~':> ...;" ,~ ,J t.~ (0 (,0 - 2 - (c) Runoff or climatic conditions below the reservoir such that Holly flows would be in excess of 2,000 c.f.s., with con- siderable amounts of water passing Garden City. (d) Inflovfs of such amount or duration that there would be no doubt that sufficient storage would accumulate for a find~ ing of water in the reservoir. The classification in which the various floods might, be placed is indicated on the attached tabulation. This segregation is a matter of judg- ment and is based on inspection of mean daily streamfl~fs and diversio~ as recorded. A detailed study of hydrographs, together with definite knowledge of climatic and ground water conditions, might result in a somewhat different segregation. H~'ever, this analysis should be a reasonable indication of what might be expected to occur during a period of water supply such as that of the years 1931 - 1953. .:. It would appear that significant storage might be possible for floods with mean daily flow on the first day in excess of 5,000 c.f.s." with- out any material detriment to interests above or below the reservoir, if re- leases should be made at those times for diversicn requirements in Water Dis- trict 67 only. The same thing is probably true for inflows between 2,000 and 5,000 c.f.s., with durations of four or more days. Excluding those, there would remain 22 floods in the 1931 - 1941 period, and 17 floods in the 1943 - 1953 period for further consideration, all with mean daily flows on the first day between 2,000 and 5,000 c.f.s., and with durations of from one to three days. For the eleven years prior to the operation of the reservoir, if 10 of these floods fall in classification (c), there are l2 remaining in clas- sifications (a) and (b). Of these, 3 would probably be in classification (a), which includes inflows of one day duration, from which water users in Kansas historically derived minor benefits. The remaining 9 floods in classification (b) which occllred in the eleven years are those during which water users in Kansas historically made substantial diversions for periods of from two to four days. On a similar basis for the 1943 - 1953 period, there would be 12 floods in classification (c), 2 in classification (a), and 3 which would have a (b) classification. There would thus be a total of 12 classification (b) floods over the period of twenty-three years considered.
