indicated a total of ;338, 900 acres

Quoting from the report pre-
sented to the committee by Mr..
Anderson:
"In considering project acreage,
we have pointed out that the des-
ignated project area with water
rights is 1OO,546 acres ApprQxi8.
mately 1850 additional acres are
located under the project works
and receive service through them.
A portion of these lands. are in the
old Florence-Casa Grande project
and have rights under the decree.
The balance is contained in lands
belonging to:the state and operated
as prison farm near Florence.
The total acreage under project
works is thus estimated at 101 800
600, ,546+1, ,250) acres.
"The assumption is made that at
full development the project will
irrigate 80 per- cent of ,its-.Gross
area, since areas taken in roads.
canals, urban areasy homesites.
etc., are about 10 per cent Of the
total. This results in a. total area
of 81 ,62O acres requiring irrigation
water.
"An average annual requirement
of 40 acre feet per acre delivered
at the land is estimated as neces-
sary. This would :resultsin an av-
erage total project requirement OF
365, 4SO acre feet each year, for de-
livery at the land. Z. .gGsss Gs
with the application, Of approx
imately 40 acre feet per sacre each
year, it is estimated that pumpage
can be supplied by project pumps
in an average annual amount OF
O.75 ac. ft. for each acre, fAeliv-
cred at the land, total delivered
amount of .6S, ,715 acre feet. This
leaves balance of 297,7e5 acre
feet to be obtained from gravity
sources. With losses in the sys-
tenn totaling 80 per cent, there
would thus be required at project
diversion points, a total of 425, 1880
acre feet of gravity water.
"It has been shown that the d1-
vertible supply to the project since
1880 has averaged 245,306 acre
feet, indicating an average a1pua
deficiency for the whole project OF
approximately. 100000 acre feet.
