of the construction OF an All-Ameflcan
Canal should be the enlargement of the
Yuma canal and its headworks and the
construction of an extension of the en'l
larged canal at capacity of either 5000
or 5000 second-feet depending upon
whether the All-American Canal is to be-
constructed by Imperial District alone or
by the district with the assistance off
the outside lands of Imperial kalley>i
down to Pilot Knob and the installation
of a power plant for construction pur
poses at that point.
The power plant installation for con
|struction purposes at Pilot Knob should
be for the utilization of fall of about
80 feet and the arrangement should bel
such that if necessary the capacity of
the plant can be increased. Provision
may sometime in the future have to be
made also for standby gasoline or
steam power plant, but this is not in
cluded in the works now necessary. III
power is required at any time for oper'
ating gates when there is no water in
the canal this will be obtainable from
the Southern Sierras Power Company,
whose transmission lines have already
been extended into this district.
| On the All-American Canal at two
points fall can be concentrated and
power should be developed. This is to
be done at or near the points marked
Power House" on the General Map"
which accompanies Mr.. Preston's report.
| The plants at these points will be
referred to as Power Plants Nos. l and 2.
Tue installation should be for the utiil
zation of 5000 second-feet falling about
! 80 feet at the first station although at
| first only "a feet of fall are to be util-
izeD and $500 secOnd-feet falling about
! AT feet at the second station.
| The total cost of constructing the All
American canal as described in Mr..
PrestOn's report at a capacity of 5000
second-feet, not including the two power
plants on the mesa, is estimated at $26,
I732,6O2 This includes $1,900,000 to be
paid to the United States in installments
without interest for the right to connect
with he Laguna Dam and utilize di
Iverting works in common with the Yuma
project.
The total cost of constructing an
All-American Canal for Imperial Irri
cation District only, at capacity of
5000 second-feet, not including the two
power plants on the mesa, is estimated
to be paid to the United States in in
stallments without interest, for the right
to connect win the Laguna Dam, and
to utilize diverting works in common
with the Yuma project.
! The amount which should be charged
by the United States to an All-American
Cana lproject with canal capacity of
5000 second-feet which is to supply
water to an area of 100000 acres, for
the privileges of connecting with the
Laguna Dam, has been estimated at
81, 10000 This amount should be ap.
portioned to the Imperial Irrigation Dis
trict and to outside lands in the proper
ton of the contributing areas. 1t will
be payable in installments to be fixed
by the Secretary of the Interior eX
tending over a period of 20 years with
out interest. The Imperial Irrigation
District should Obligate itself, as is con
ltemplated by the agreement of Octo.
ber 23rd 1918, between the Secretary
| of the Interior and the Directors of I'm
perial Irrigation District, to make the
payment of it's proportional part of this
sum or in round numbers about 60 per
cent thereof.
The amount which should be paid by
Imperial Irrigation District to the United
States for the privilege of connecting
with the Laguna Dam, if an All-Ameri'
can Canal is constructed at capacity
Fof 5000 second-feet to supply water
only to lands within the Imperial Irri
CATION District, is $1,6000,000. This
amount will be payable in installments
extending over period of 20 years with
out interest.
The agreement under which this Board
is acting makes ii imperative to con
slider olny high-line canal located en-
tirely on American territory. The un
fortunate position of the boundary lineI
interferes with the consideration of a,
location further to the South, which
would in all probability be better adapted
to the configuration of the ground.
The agreement of October 23rd, 1918 |
between the Secretary Of the Interior
and the Directors of the Imperial Irri
CATION District provides for the con
struction of an All-American Canal byl
the Imperial Irrigation District Should
the District fail to construct an All
American Canal as contemplated under
this agreement, the question Will then
arise on other methods of procedure |
The Board believes that means must
be found for extending the irrigation in
the Imperial Valley to the mesa and
other lands that can be commanded by
canal from the Laguna Dam, and that,
from an engineering pointcof view there
would be material advantage in canal
location not restricted by the interna |
tional boundary. After a nighttime cana
has been constructed under the pend
ing agreement or otherwise, the United
States should make provision for the
necessary sub-mains and laterals toI
serve the lands which are outside of
Imperial Irrigation District and dispose
of the public lands, granting long time
in which to make payments and low
rate of interest on deferred payments.
The canal has been planned as an
open canal through the sand hills The
canal banks are to be fairly fiat on
slopes of 2 to l and bernie, 30 feet
wide, is to ebprovided at the surface
of the mesa formation which is the
base of the sand dunes The Board is |
Of the opinion that the drifting sand
can be checked by proper disposal or
