<br />the basin have been re-surveyed aIld re-measured in recent ye~rs <br /> <br />by the Bureau of Reclamation, and knowing also that crop report <br /> <br />information or irrigated acreage is available for the year 1937 <br /> <br />and the present time for the Uncompahgre Valley in Montrose and <br /> <br />Delta CounUes and for the Grand Valley in Mesa County, a tabu- <br /> <br />1ation of comparative irrigated land acreage figures were com- <br /> <br />piled for the five areas. The results of the tabulation for <br /> <br />the five study or sample areas is as follows: <br /> <br />SUW1ARY OF INCREASE OF IRRIGATED LANDS OF WESTERN COLORADO <br /> <br />Location of Irrigated Irrigated Increasl Percent <br />Sample Area 1937(Acres) 1952(Acres) in Acres Increase <br />Colo.River Basin <br />above Pali3ade 162,910 195,)00 )2,390 19.9 <br />San Miguel :Ri ver <br />Basin 19,980 24,270 4,290 21.5 <br />Little Snakl~ <br />River Basin 11,180 13,740 2,560 22.9 <br />Uncompahgre <br />Valley 62,270 71,230 8,960 14.4 <br />Grand Va1l6lJ' 63,200 74.980 11.780 18.6 <br />TOTAL 319,540 379,520 59,980 18.8 <br /> <br />The I'esul ts of the study af the five sample a~, which <br /> <br />constitute 42% of the irrigated lands of the basin show that an <br /> <br /> <br />average increase of 18.8% has taken place between the years 1937 <br /> <br />and 1952.
