<br />The above table indicates the irrigation development of the Colo-
<br />rado Hiver Basin since 1902, or illustra.tes "Claiming the Basin" for agri-
<br />cultural purposes durine; the past 40 years, and is not inconsistent with
<br />data appearing in the Report for the Bnsin as a whole. The table at page
<br />27 shows 2,400,000 acres irrigated in 1922, whereas the above table shows
<br />2,312,546 acres in 1919 and 2,537,124 acres in 1929. Later in the Report
<br />a figure appears of slightly more than 2,600,000 aores, which represents
<br />the present irrigated a.creage exo.lusive of allowanoes made for irrigable
<br />lands of existing and authorized projects to be irrigated in the future,
<br />which figure is substantially the SlUIle as the 2,601,963 acres reported by
<br />the u. S. Census Bureau for the season of 1939, although there are unex-
<br />p lained differences in the fi gure s when considered by individual states.
<br />Colorado questions the advisability of reporting information concerning
<br />lands considered irrigable in 1922, unless it can be shovm that the deter-
<br />minations v.ere based on land c lassifica.tion definitions that were uniform-
<br />ly applied in both basins and Nations. Information conoerning develop-
<br />ments in Hexico would not como within the title of the Report. 1!hatever
<br />data regarding Mexioo may be justified for inclusion and presorvation in
<br />the Report, if any, might better appear in the following Chapter entitled,
<br />"Jividing the Hater," and in the section thereof entitled, "BetweGn the
<br />United States and Hexico." Colorado points out that the irrigated acreage
<br />in the Basin, according to the above table, increased from 927 ,183 acres
<br />in 1902, to 2,601,963 aores in 1939; and suggests that the Bureau of Re-
<br />clamation segregate the increase of 1,674,780 acres as between federal
<br />and private developments. In this connection Colo~'9.do notes thnt the irri-
<br />gated acreage in the Colorado River Basin in Colorado inoreased from
<br />417,1339 acres in 1902 to 844,494 acres in 1939, and says that the increase
<br />of 426,655 acres in about 40 years may be attributed to federal develop-
<br />ments to the extent of 90,012 acres, and to private developments to the
<br />extent of 336,643 acres.

<br />of the factors said to have motivated the negotiation of the Colorado Ri-
<br />ver Compnct, and is arranged in tVIO parts entitled, "Between the Upper and
<br />LoVler Bnsins;" and "Between the United States and i'jexico." Subject headings
