E. Water Using Areas Influenced by Man

The same procedures ,tere follo\-led in determining the water

using areas influenced by man for water years 1946 through 1951

as described in the report for the 1914-1945 period.

1. Irrigated Areas

The average area irrigated for the 1946-1951 period and the

area irrigated in 1951 in each state within the natural drainage

area of the Colorado River downstream from Lee Ferry to the

Arizona-Sonora Boundary and in Mexico within the drainage area

of the Gila River were determined to be as follows:
Arizona California Nevada New Mexico Utah Mexico Total
1%6-1951 Average Irrigated Acreages
84l,167 62,730 11,467 17,060 22,127 3,963 958,514
1951 Irrigated Acreage
1,033,514 69,926 12 , 141 18,546 22,340 3,960 1,160,427

Acreages irrigated annually in individual areas and states are

listed in Tables A-I through A-5 of the appendix to this supplement.

2. Cropped Areas
Table MS 5 summarizes the average acreage of the various crops

cultivated during the 1946-1951 period in each state within the

natural drainage area of the Colorado River downstream from Lee

Ferry to the Arizona-Sonora Boundary and in Mexico within the drain-

age area of the Gila River. Crop acreages for 1951 are listed in

Table !1S 6.

3. I.rater Consuming Noncropped Areas
Table MS 7 summarizes the average acreage of the water consuming

non cropped areas within the natural drainage area of the Lower Colorado

River Basin during the 1946-1951 period.
