ARROWROCK dam To
BE COMPLETED
BY 1916

In the last issue OF The Tribune
we published, letter from the sup
ervising engineer and project manager
of the Boise project which gave a
great deal of general information in
relation to the amounts of money al
lotted for use on the Boise project
during the calendar year 1914. We
herewith publish statement from the
construction engineer of the project
describing in detail the operations at
Arrowrock and explaining how the
money will be spent.
1t is the intention of the Reclama-
ton Service to rush the work on the
Boise project that it may be COM
pleted at the earliest possible moment.
We believe that the following state
ment will prove interesting to readers
of The Tribune:
Storage Unit of the Boise Project.
Status and Probable Progress.
Sufficient funds have been provided
by the Secretary of the Interior for
the carrying on of the work at Ar
rowrock during the year 1914 at the
highest rate of speed consistent with
proper economy, and it is expected to
have the dam finished during the win
ter of l9l5-l6, so that water may be
stored for use during the irrigation
season of 1916.
Scope of Work.
The principal object of this work
is the construction of the Arrowrock
the building of the Arrowrock Dam
and spillway across the Boise river
at a point about 20 miles above the
- e - T.. -
this work to the best advantage, the
construction and operation of several
occidental features was necessary, the
POST impc tant them icing:
The Arrowrock Railroad IAN
dard guage road II miles long, con-
Meeting Barberton with Arrowrock.
Over this railroad all equipment, ma
terial and supplies for the work at
Arrowrock are transported, and the
saving in cost of transportation of &C.
ment alone will very nearly pay for
the entire cost of the railroad;
The Boise Power Plant-built at
the Diversion Dam, at the head of the
New York Canal for the purpose Of
furnishing electric power for the OPP
Grafton of the construction equipment
at Arrowrock. This plant has max
imum capacity of about 5000 horse
power, and the power is transmitted
to Arrowrock over duplicate trans
mission lines at $4,000 volts. Besides
furnishing all the power used at Ar
rowrock, large part of the output
OF this plant is being sold for CONNER
cial purposes, the receipts from this
source at present nearly paying the
cost Of operation of this plant;
A Telephone System connecting
the Boise Office of the Reclamation
Service with Arrowrock.
A Wagon Road around the Reser-
voir above the flow line to replace that
portion of the old road up the river
that will be flooded by the reservoir;
A Sawmill located on Cottonwood
Creek, at a distance of about II miles
above Arrowrock, where practically
all of the lumber used for the work
will be obtained;
A Construction Camp at Arrowrock
with accommodation for about 1000
men;
Diversion Works, with a capacity OF
10000 second-feet, for the taking of
the flow of the river out of its old
channel and around the work dur
ing the construction of the dam;
A Sand Cement Plant, with a capac-
ity of 1900 barrels per day, for fur
niShing the sand-cement used in the
construction of the dam; and the as
Senbling and installation of an ade-
quate construction plant for carrying
on the work rapidly and economically.
