agement combined with skillful farm
ing, the project can be made a success,
DR.. WOODBURY. concludes, adding that:
ssThe margin of safety is not large,
however, and no opportunities must be
overlooked to avoid waste and careless
ness in the pumping, distribution and
use of irrigation water. Cooperation
in the conservation of water IS essen
tial on the part of all concerned If the
project is to prosper instead of going
the way of Burbank and Alfalfa"
A classification Of lands in the en-
tire project, between the main canal
and the Columbia river, based on the
United States soils map Of 1919, the
Kenny Stevens soils map of 1905 and
the personal inspection Of the project
by DR.. WOODBURY., shows a total area
of 1914 acres, of which 1926 acres
are classified as Glass 1, 1914 acres as
Glass 2, and 6944 acres as Glass 8.
In Glass l are included those lands
recommended for continuation of pres
mediate development by extending irrl-
cation water to them, requiring only
minor extensions of the present dis
tribution system. Glass lands are
questionable as to the ACCESSIBILITY OF
continuing present irrigation on them,
or are recommended for later devel-
opment when economic conditions war;
rant and when the district is in po-
sition to make major extensions OF
the distribution system. OF Glass 3
lands, the engineer sees no feasibility
! of irrigating now or at any future time
unless unforeseen crop developments
! or economic changes occur
| One of the recommendation Of the
report is that lands now irrigated by
E lateral be withdrawn from cultiva-
ton in favor of better lands in the
project at least until major extern
sions of the distribution system are
undertaken. Reasons for this recon-
mendation are that these lands are
generally of a poorer soil type, are iso-
lated from any compact block OF irri-
gable lands, and the delapidated con-
dition of the pipe line on the lateral
This wood pipe has served long past Its
expected life, it's maintenance cost is
high and complete replacement cannot
be postponed many seasons. Abandon
ment of the lands irrigated from the
upper part OF this lateral would relieve
i the district of the expense OF replac-
ing the pipe; while few tracts now
irrigated from the lower end OF this
lateral which are in better soil class
can be irrigated from other laterals
} the report says.
FL Per Cent In Peak Month
Much can be done toward NOR
successful operation of the project p.
spreading the water ordinarily pumped
and delivered during the irrigation sea
son over more land than is now irrl
! gated, the report contends and from
, summary of data applying to light soil
similar to those of the Priest Rapid
project and from observation of actua
irrigation practice in this project an
!. in other places, it is recommends
: that an official farm duty of water i
this project OF u acre-inches OF waite
per acre for the irrigation season b
established, with the provision tina
. q per cent of the total seasonal al
lowance be made available in the pea
month of July
Il The resulting peak rate of deliver
f to the farms in the project would 3
. l cubic foot per second to SO acre
c and the average rate of delivery IL
c the 7-month season would be l CT
o to II acres.
n This peak rate of delivery of CT
IS to SO acres would amount to Is incht
If depth in a 31-day month, thus allow
ing three 5-inch irrigations per mont
d on fine sandy loan soils, four 3%
,e inch irrigations on sandy loan, ar
l. five 3-inch irrigation on sand.
