NEARING COMPLETION - The final load
of clay was placed and packed into place
In the Trinity river dam in northern Cali
fornia recently. This picture shows the dam,
at lower left, nearing completion. It was
taken from a lookout point near the proj
ect, which will cost an estimated $49 million
when complete. Work on the dam was start
ed several years ago.
Riprap Is Placed
On Big Earth-Fill
Dam in California
By KATHERINE CHAPMAN
Mail Tribune Correspondent
"What will you do without
water? was the thought-
provoking question asked in
advertisements appearing re
cently in many nationally
circulated periodicals.
In an attempt to guarantee
that this and future genera
tions in California may not
have to learn the devastating
and death-dealing answer to
that question, a plan was
spawned in the minds of gov
ernment engineers. And thus
was brought into being the
Central Valley Project in Cali
fornia. The construction of the
CVP got actively under way
in 1937, and by August, 1951,
all the works comprising the
initial project were in opera
tion. These included Shasta
Dam, Delia Cross Channel,
Dclta-Mcndota canal, Friant
dam, Madera canal, Triant
Kcrn canal, Contra Costa
canal and a power transmis
sion system.
Regulate Water
In addition to these units,
Keswick dam was authorized
and built to regulate the fluc
tuating power releases from
Shasta Dam and to add to the
power capacity of the project.
In 1949, Congress authoriz
ed the construction and opera
tion of the American river
unit, including Folsom dam
and power plant. Nimbus

Sly Park project as part of

the CVP. All features of the
project have been integrated
into a unified operations sys
tem. Now the project is being
further expanded by the con
struction of the Trinity di
vision of the CVP.
Transport Water
These works will operate to
transport an average of 865,
000 acre-feet of water from
the Trinity river watershed
into the CVP system each
year.
(An acre-foot of water is the
amount of water covering one
acre to the depth of one foot.
This is equivalent to 43,560
cubic feet, or a cubic foot per
second for 12 hours.)
The power facilities will
have some 384,000 kilowatts
of generating capacity.
Work on Trinity dam was
begun several years ago, and
on Sept. 23 this year, the final
load of clay in the Center of
t h e $49,000,000 dam was
tamped and rolled into place.
A layer of riprap and the 40
foot asphalt road on its crest
line are now being completed.
Riprap -huge rock blasted
from a quarry-protects the
dam from weathering, ero
sion and wave action.
In Two Counties
The Trinity river division
features are located in Trini
ty and Shasta counties. The
dam is located in the rugged
evergreen country of north
ern California about nine
miles upstream from the
town of Lewiston, on the

Trinity river.
At Lewiston dam, the Trin
ity river is about 1,400 feet
higher in elevation and 20
miles west of the Sacramento
river at Keswick dam. The
town of Lewiston is reached
by driving on Highway 99 to
Redding, thence west on 299
for 43 miles, thence six miles
north on a well-marked turn
off road.
An amazing engineering
feat connected with this proj
ect is the Clear Creek tunnel.
Seventeen feet, six Inches in
diameter, this tunnel is be
ing drilled 11 miles through
a mountain. By means of this
tunnel, water will be diverted
from Trinity dam to the Sac
ramento river.
Fascinating Aspect
. To the layman watching
construction operations, one
of the most fascinating as
pects is the high-speed con
veyor system that rushes clay
and rock at a 3,000-tons-an-hour
clip from a mountain to
a river valley two miles away
-and there' is being reshaped
into this world's-highest earth
fill dam-465 feet above the
streambed of the Trinity
river.
A signboard posted on the
look-out point at the dam
site tells the rest of the story,
statistics-wise. The sign, in
part, reads:
"Type-Earth Fill.
"Structural height-537 feet.
"Height above streambed
465 feet.
"Crest length-2,450 feet.
"Maximum width at base-
2,962.
"Width at crest-40 feet.
"Volume of material in
dam-33, 180,000 cubic yards.
"Elevation of crest of dam
2,395. "Elevation of crest of spill-way-2,370.
"Reservoir area at maxi
mum normal storage -16,400
acres.
"Maximum reservoir capa-city-2,500,000
acre feet.
Usable reservoir capacity
-2,160,000 acre feet.
"Drainage area-688 squar
miles. , ., "
"Six million truck miles
will be traveled to place all;
the material in the dam.
"It would take 815,000
trains of 100 tank cars each'
to haul enough water to fill
Trinity reservoir; The requir
ed tank cars would reach
around the world 26 times, .
40 Story Building
"The dam will be as high
as a 40 story building and
two Empire State buildings
layed end to end in the river
channel would be completely
covered in the dam."
Although work is progress
ing steadily on the mammoth
project, no estimated date of
completion has been released
as yet.
And the passage by the
people of California at the re- '
cent election of the Califor
nia Water Resources Develop
ment Bond Act will enable
work on the Feather River
project to swing into action
in the near future.
Provides for Bond Issue
This act provides for a
bond issue of $1,750,000,000
to be issued by the Depart
ment of Water Resources for
the development of the water
resources of the stale, and be
comes the largest bond issua
ever to be underwritten by
any state.
Funds thus provided will
bring into being a dam on
the Feather river above Oro
ville, Calif., and a 500-mile
long man-made river to divert
the precious water from the
north to the south end of the
state.
Truly it has been said
"Water, the most important
word in the winning of the
West."

CONVEYOR BELT - This view shows the
end of a two-mile long conveyor belt at the
Trinity river dam project. The highway
where the bell terminates is just out of the
picture in the foreground. The belt, when
the project is complete, will have moved i
estimated 33,180,000 cubic yards of materia
from a nearby mountain at 3,000 tons
