F "'. �W <br />reduaad by reserving pore than 40,000 acre -faet in Narrows Reservoir <br />for new lands since all the water stored during; 1936, 1940, and 1941 <br />is utilizad by ne, land. 'Thus the water supply for 20,000 acres of <br />new land is sliwhtly deficient. An oxamination of the ot:roration study <br />for the years 1939 -1940 shows than even with a full reservoir at the <br />beginning of the 1939 irrigation seas:7n, the distribution of straam <br />f10 is so erratic that storage capacity greater Lhan 62b,000 acre -foet <br />is 4 ndica "ad as being required to regulate possible variation in <br />streauflow over a taro -year period. Both 1939 and 19 were classified <br />as dry years oa the aasis of anticipated strealualow after April 16. <br />If a reservoir of 8& ,0UU acre -feet capacity is used at :farrows <br />Logether with 30,000 acres of new land and increased return flows <br />from the Colorado -big Thompson and Blue -South Platte Pro jects, the <br />are <br />shortages wx those liGted under Operation Ito. 6 in table 2. On <br />currently irrigated lands the maximum shortage is 13.1 percent in <br />1 {i37 with a maximum acctrrulati.ve shortage of 56.1 percent for the <br />years 1934 -1941. On 30,000 acres oP new land the maximum shortage <br />is 26.4 percent in 1937 with a maximum accumulative shortage of <br />5 7.4 percent for the period 1937 -1941. Thus a project with a reser- <br />voir of 825,000 acre -foot capacity together with 30,000 acres of new <br />land is feasible from the standpoint of water supply if the Blue -South <br />Platte Project is developed as planned. <br />When the reservoir at Narrows is increased to 1,000,000 acre -feet <br />with 40,000 acres of new land together with increased flows from the <br />Colorado -Big Thompson and Blue -South Platte Projects, the available <br />water sunaly is not sufficient for a project of this size.
