and no portion of potential damalJ'ls to this area were
considered attributable to increaaing salinity. Table
3.128 illustrates these conclusions aa represented by
the zero amounts opposite the lower four categories,

were employed to estimate yield declination functions
for each crop seleeted in this area. Table 3.124 is baaed
on the resulting 'rDS water mix aa explained above
which is unique to this project.

Consequent to the resulting irrigation water mix.
the interval waa widened to include the 775 mgll
conditions. AUocation of production and land to the
various crops is presented in Table 3-125. These
aggregated totals remained at the same levels over
the entire TDS interval under study. However,
sub.Appendix M should be consulted for a detailed
analysis of model allocations to respective land classes
and technologies.

The foUowing two tables (Tables 3-126 and 3-127)
contain constant amounts. 1<'or example, Table 3.128
shows 233,816 lie it of water consumed out of a
possible 240,000 ac it available. No change is observed
between 775 and 1400 mg/l. Likewise, In Table 3.127,
the objective function estimated net profit to be
$8,332, 477 for the whole area and $158.72 per acre.
These amounts were also constant over the interval in
question. Subsequently, no differences were deteeted

Additional land is projected to be brought under
irrigation by introduction of Central Arizona Project
(CAP) water to the Indian part of the San Carlos
Project (Map 3.14). Tabie 3-129 indicates that
approximately 21,170 acres will be under Irrigation.
Lands are assigned to specific drainalJ'l classes aa weU
aa their feaaible possibilities in relation to double
cropping.

Most of the same crops Were selected in the
Indian part aa were chosen to be major in the
non-Indian part (Table 3-130). One eddition is that of
watermelon. The matrix of double cropping possibili-
ties is slightly larlJ'lr than in the previous area,
however, land area avaUable for this activity is much
less.
