A later Bureau of Recla/J"ation <br />study shows that irrigaion by the year 1951 had been expanded <br />to a total of 83,584 acres. A field reconnaissance study in- <br />dicates that the amount of land presently irrigated is 80,320 <br />acres, an expansion of 22,310 acres for an increase of 38.5~ <br />in the 25 year period 1939 to 1964. <br />A study of the location of the irrigated land in <br />relation to the availability of water indicates that approx- <br />imately 61,670 acres of the 80,320 acres receives a full or <br />nearly, full supply of irrigation water and 18,650 acres are <br />in need of additional water for full crop production. <br />The population of the subbasin as given in the 1960 <br />census reports is 6,546. This includes the population of the <br />several cities and towns as well as the ranch population. <br />The sUbbasin 1930-1960 population growth was 2,621 for a 67% <br />increa$e. The strealT, depletion chargeable to don.estic, /J;uT\- <br />icipal and industrial use of water and reservoir evaporation <br />is estimated to be 7,400 acre feet, including allowance for <br />transient population. <br />The transr.ountain diversion of water for use in <br />Eastern Colorado has expanded until in the /J;ore recent years, <br />it far,exceeds the use of water in the subbasin. During the <br />last 5 years of t]-,e study period ending in 1960, the water <br />exported averaged 367,000 acre feet per year. This included <br />the unusually high runoff year of 1957.
