<br />-7- <br /> <br />-- <br /> <br />In this connection, it may be observed, that the natural flow of the <br /> <br />-Arkansas-River-at-Pt:eliloinI943, as-d-isclosed by the Daily River Reports as <br /> <br />corrected for increased releases of transmountain diversions by the Colorado <br /> <br />.~--:::; <br /> <br />canal, was about 90 percent of normal. The flow of the Purguitore at the <br />N <br />~ Highland Dam was about 15 percent of normal and that of other tributaries much <br />-.J <br />,... less than normal. <br /> <br />The attached tabulation shows that the Fort Lyon can..l which diverts no <br /> <br />water from upstream reservc'irs, apparently diverted 14,490 acre feet less water <br /> <br />in 1943 than its average historic diversions. An analysis of diversions by <br /> <br />other canals above the Fort Lyon, on dates when its second priority.was not <br /> <br />being satisfied, discloses that this was the result of some excessive diversions <br /> <br />by upstream canals and the requirements at times that the Fort Lyon pass more. . <br /> <br />water by La Junta than should have been required; also to the failure.on the <br /> <br />'. part of the management to divert all the water which was available to it on <br /> <br /> <br />certain dates, and finally to the fact that natural river flow through Pueblo <br /> <br />during the six months period was subnormal. <br /> <br />A further analysis of the large addition..l diversions maoe by the Catlin <br /> <br />canal were, at least partially, due to the regimen of stream flow which per- <br /> <br />mitted a longer period of diversions than in average years, and wtich also <br /> <br />I, <br /> <br />would adversely affect the amount of diversions under the Fort Lyon second <br /> <br />priority. No attempt has been made to determine the cause of lesser or greater <br /> <br />diversions by other canals in 1943, than their average historic diversions. <br /> <br />The foregoing statements and conclusions are subject possibly, to some <br /> <br />corrections following further analysis of all available records. <br /> <br />. <br /> <br />In conclusion, I desire; to express to the Water Users and to the Manage- <br /> <br /> <br />ment of all of the Colorado canals and their Attorneys, my sincere.appreciation <br /> <br /> <br />of_the _tol",rance_ displayed -by-them during - this .rather- trying -perTod;--- - - -- <br /> <br /> <br />?h-"~ <br /> <br />. , <br />State Engineer <br />
