<br />6 <br /> <br />GENERAL <br /> <br />insofar as raw woter supplies are concerned, comprise the 23- <br />mile Harold D, Roberts Tunnel which will bring Blue River water <br />to the South Platte, and the 3-mile Vasquez Tunnel which will <br />transport water brought through Jones Pass Tunnel back across <br />the Continental Divide into Vasquez Creek. The water brought <br />through the Vasquez Tunnel will then again pass under the <br />Continentol Divide through the Moffat Tunnel and be processed <br />by the same focilities which process Fraser River water, Other <br />works embody the completion of lining of the Moffat water tun- <br />nel, and the enlargement of Williams Fork replacement reservoir <br />to its full decreed capacity of 93,637 acre-feet, <br /> <br />Hereinafter whenever Moffat Tunnel water or Moffat <br />System water is referred to it is intended to include the water <br />derived from the Fraser River and its tributaries and the water <br />derived from Williams Fork River which is transported through <br />the Jones Pass Tunnel and thence through Vasquez Tunnel to <br />the Fraser System, <br /> <br />The estimate of the amount of water that will be available <br />to the City on completion of the present construction program <br />was based on the water supply available during such a period as <br />1931 through 1954, This period was selected because it repre- <br />sents one of the most critical periods of recorded water supplies <br />in the Rocky Mountain Region, It was not only in itself a long- <br />time critical water supply period, but within it there occurred <br />some years of lowest recorded runoff in this area, <br /> <br />The estimated amount of water available to Denver from <br />her several sources during a period such as occurred from 1931 <br />through 1954 is portrayed graphically on Figure 2, It should be <br />noted that these charts show only the total annual supplies avail- <br />able from the several sources during each year of the study <br />period, and do not portray the seasonal variations in flow within <br />the year, <br /> <br />Table No.1 is a summary on an annual basis of Denver's <br />present water suppl ies and those that wi II be developed after <br />completion of the present construction program, The values <br />shown in this table, as well as on the charts on Figure 2, represent <br />total estimated supplies measured at their sources assuming that <br />
