This sun~ary is based upon information from the U. S. Bureau of Recla-
mation.

1. DIRECT BENEl'ITS................................... . . . . . . . . . . . , . . $ 5 103 000

Assumes project water supply of 78 1130 AF delivC'rnble to fllrm
heaJgates, projected crop yields [or the year 2010, and normalized
prices (whi,ch are significantly lower than current prices). 78 430
AF is enough water to supply 123 fully-irrigated farms, representative
of those in the project service area "[11 t.:1H..~ Yc"\.nr 2010. ThoBe far.ms
would occupy 108 000 acres, enough [or approximately 49 dryland
farms, representative o[ dryland farms for the year 2010. Total
net incomes were compu,ted for the two classes of farms. The differ-
ence in these not incomes is the amount shown.

2. INDIRECT BENEFITS...............................................$ 1 374 000

Total indirect economic activity generated by the two classes of
farms described above were computed, using a factor for each com-
modity. The differnce in illdi,rect economic activity generated by
by the two classes of farms is the amount shown.

3. PUBLIC BENEFITS........... .'...................................... $

255 000

5% of direct benefits.

4. GROSS BENEFITS................................................... $ 6 732 000

5. DIRECT ADVERSE EFFECTS.... .'.....................................$

148 000

This 'is an opportunity cost to labor, anJ represents alternate
earnings ("summer wages") of $2000 for each of 74 farms. (Note
that 74 is the difference'between the number of fully-irrigated
farms and drylann farms described in, 1. above.) .

6. IND IRECT ADVERSE EFFECTS........................................ $

278 000

This represents the unavoidable loss of indirect economic activity
due to tl~e changes 'in agricultural production in the "take area"
and vicinity. First; the crop value (using crop yields projected
for the year 2010 and normalized prices) for the following types
of land in the take area are computed: pastureland; dry cropland;
estimated dry cropland potential of presently irrigated land.
Second, factors are applied to each type of crop to compute inJirect
adverse effects.

7. PUBLIC ADVERSE EFFECTS... . . . . . . . . , . . . . . . . . . . , . . . . . . . . . . . . . . . . . . . $

32 000

2~ per cent of total crop value computed in 6. above.

8. TOTAL ADVERSE EFFECTS.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $

458 000

9. 'TOTAL ANNUAL NET IRRIGATION BENEFITS....... ,....................$ 6 274 000

Line 4 minus line 8. Does not include $22 000 i.n annual. AM&R savings
(irrigation interests).
