valley than when taken from the owens
river.
Outline of Plan of Works
"The plan contemplated the building
of an, ,aqueduct of sufficient capacity to
deliver continuous flow of 400 cubic
feet per second, or 10000 miner s
inches, as it is locally considered and
measured. Starting at the point of in
take on owens river, about twelve miles
above the town of independence, or
two miles below a basaltic mound in
the valley Galley "Charley's Butte" the
main canal to the Haiwee reservoir, a
distance of sixty miles, will have a.
capacity of 700 to 900 cubic feet per
second, starting with 700 second feet
and increasing as the side streams are
crossed until Cottonwood creek is
reached, from which point TO the reser-
voir the capacity will be 900 second feet.
"This large capacity is provided for
the purpose of gathering as much of
the flood discharge as is practicable,
and conveying 1t to the main storage
reservoir at Haiwee meadows, whence
1t Is to be drawn at a uniform rate of
400 second feet, plus an additional
amount, estimated at 10 cubic feet per
For the first 20 miles through the
Owens valley the canal will be suffi-
ciently below the normal water plane
in clayey soil of close texture to require
no lining, but for the lower 40 miles
from the point where it begins to skirt
along the flanks of the Alabama hills
through to the reservoir it will be lined
on bottom and sides with masonry laid
| in Portland cement and plaStered in a
manner intended to prevent q loss of
water, thus forming canal of suffi-
cient stability to Withstand all ordinary
vicissitudes.
"The elevation of the hydraulic grade
at the head works is 1920 feet above sea
level and the proposed high water line
of the reservoir is 1850 feet, giving a
total fall of 60 fet to the canal, or an
average Of one foot per mile from the
intake to the Haiwee reservoir.
Aqueduct from Haiwee Reservoir to
the San Fernando Valley
"From the outlet of the Hawee
reservoir dow water elevation 3695), to
Little lake, distance of 1916 miles,
through Rose valley, there is a total
fall of $40 feet. Under the revised
plans 270 feet of this drop may be made
available for power whenever the de-
mands will justify it's development.
ture it now appears best to construct
this 15 miles in the form of an open
conduit of small sections lined with
masonry, following the smooth ground
in the Rose valley along the steep
natural gradient, thus utilizing the fail
to increase the velocity of the water
and lessen the size of the conduit.
Whenever demand comes for the
development Of power in this somewhat
remote locality new line of conduit
can be built along the higher gradient,
of power. After more complete sur
veys Of the high line it may be found
that its additional cost need not defer
it's construction, especially If there is a
prospect of the demand in the not dis
tant future for the 1000 horse power
which can here be developed.
From Little lake to Indian Wells, a
distance by the conduit line Of 24.5
miles, is a section of more difficulties
supported on the mountain sides at
an elevation of 200 to 500 feet above
the valley along which the high
way follows at the base of the Sierra.
Here a succession of tunnels, siphon
pipes and bench conduits eXcavated
much of the way in solid rock and
covered from the outset with rein
forced concrete, are required The
siphons are eight in number, having a
total length of three miles and a maxi
mum head of $50 to 400 feet, while the
tunnels have total length of five
miles.
From Indian Wells the line enters
upon a section of smooth open valley
land extending nearly to Red Rock
canyon, a distance of 20 miles, whore
the excavation will be comparatively
easy with only $3.50 feet of steel
fumes and siphon pipes for crossing
dry washes that come out from the
mountains.
Beginning at the summit of the
ridge dividing Indian Wells valley
from Red Rock canyon and extending
a distance of 21,6 miles the second
difficult section of the work is en-
countered, requiring about eight miles
and siphons and 10 miles of concrete
lined and covered conduit A con-
siderable portion of the distance, how
ever, is through indurated clay, sand
and shale which is not difficult of ex-
caVation, although extremely broken
i'm surface topography. In this diVl-
sion the line must be carried across
Jawbone canyon with a siphon pipe
having a maximum head Of $50 feet.
"After passing this broken ground
the conduit energies upon the smooth
plains of the Antelope valley, where a
canal may be built with a minimum OF
cost, crossing the Southern Pacific
railroad some two miles north OF Mo-
fave and extending entirely around
the head of the valley west of Neen-
aeh to a point nearly south of Fair
mont. In all this distance of 64.5 miles
there are but two exceptions to the un-
