There 36.2 sec. IT,. flows southwark In
Ito the Tonasket lateral and 9.4 sec. it..
flows north into the Cordell lateral
THE pipe IL "a in, In diameter and
45S8 IT,, long. Both ends are belled tc
"a 40 In. diameter In length Of IL IT
THE inlet structure IL OF wood and de.
Isigned to reduce entrance losses to a
minimum. At the outlet no special at.
tempt was made to recover velocity
head. The pipe ends in 4 concrete well
which discharges into a large wooden
box with weirs and flashboards for
controlling the division Of the water
to the two branches.
The Tonasket siphon carries 16 sec
It. through Tonasket and across Bona
parte creek. 1t is 371S IT, long, made OF
continuous wood staveS and is 26 In.
in diameter. Through the town the
Ipipe is buried under streets and alleys
On account of the low hlsads the buried
portions were given three coats OF
] coal gas tar instead Of two as was
the case with the other pipes.
The siwash siphon, 5s3 It. of 26 In,
continuous wood stave pipe: the
the Whitestone siphons GAL IT,. Of 2S
In. pipe: the Ninemilt and Cache
Creek siphons. of 4SS and 498 IT. re-
spectively of IS in.. machine banded
pipe. and the Peterson Creek siphon,
276 It.. of le In, machine banded pipe,
were built in addition TO those before
mentioned.
The slaves of all continuous stave
|pipe for all static heads Of less than
|20 It. were given 10 min, bath in hot
|firoleum. After construction all pipe
was panied with one coat of water gas
|tar, and one coat where exposed or two
or more coats Of coal gas tar where
buried.
The macine banded pipe for all
heads less than 20 feet was given the
|hot firoleum bath after winding. All
pipes were dipped in hot tar and as
|pheltum before shipment.
The joints of all machine banded
pipe were of the insert type. No sieve
joints wore used. The insert is not SO
elastic as the sleeve Joint. since with
the former a deflection of ~ in, at
each Joint Is about the limit. Sharp
curves we're made by the use of REIN
forced concrete elbowsfa as shown. The
portion Of the pipe iinbedded in the
concrete was thoroughly cleaned Of
all tar by first scraping and then
|scrubbing with caustie soda. The re-
suits were very satissactory and no
leaks have been defeated in any of
them.
The Distributing lAsSrals were de-
signed to. deliver We AkSor irrigation
under the rotation plan. As the lands
are somewhat rolling. minimum of
2 sec., IT,. vas allowed in all distrib-
|uting bitches, fumes and pipe lines.
All laterals and deliveries were de-
|signed with trapezoidal weirs In earth
sections and suppressed weirs In the
fumes. The system was constructed to
carry water to each 40-acre tract or
lot. Water is delivered to the
high point In each tract, or where i'm
practicable, to the margin Of the tract,
lat sufficient elevation to reach the
high point.
Headings from the larger canals are
|of steel and concrete. The steel head
gates were specially constructed for a
|34-deg. slope by the Columbia Engin-
|eering Works Of Portland. The top is
supported on an extension Of the cut
loft wall, which makes a simple and ef-
fective installation.
The cement pipe used in the distri-
button system was made on the shore
|of Lake Osooyos and hauled to the
place. Plain pipe with male and female
joints were used. In laying the pipe In
1.-THE trench the male end was touched
|up with mortar before joining, and a
wrap Of mortar was made by rolling in
Ia piece Of cheesecloth long enough to
reach around the pipe. BY wrapping
this roll Of mortar around the outside
[of the joint and patting it with the
hand q practically water tight joint
was secured.
The affairs of the district are admin
|istered by a board Of three directors
elected from among the land owners.
H. X. Bowen of Tonasket is president.
Erwin Truax and George I. Cole of
Oroville constitute the board of di-
|rectors; E. Riste OF Oroville is secre-
|tary and J. Criswell, irrigation man
ager.
During construction, D. c. Henny Of
Portland was consulting engineer, R.
IF. Hoffmark was superintendent for A.
Guthrie & Company, the contractors,
and the writer was engineer in charge.
All wood pipe was furnished by the
Portland Wood Pipe Company Of Port
land.
