YUMA VALLEY AREA

In addition to several previous areas mentioned,
Imperial Dam also diverts water for the Yuma Valley
area (Map 8-8). Irrigation occurs on approximately
57,900 acres which are classified In respective classes
by Table 8-78. Double cropping is practiced to a
greater extent In this area than occurred In the Gila
area. Still, only about 10 percent of the irrigated acres
are used In this way. Table 8-74 shows the various
camblnatioDl of cauble cropping rotations assumed to
be feasible.
