syphons will be Of structural steel
Wooden fumes over creeks and shall
low gulches will be carried on pile or
frame trestles
At the Yakima river crossing the
water viii be carried in a syphon
eight feet in diameter and $500 feet
long, consisting of 400 feet of wood
en- stave pipe, and LOO feet Of riv-
eted steel pipe. The maximum head
on the steel pipe will be about $40
feet. The pipe will be carried over
the river and the Northern Pacific
railroad on a steel bridge about 500
feet long, forty feet above the bed Of
the river
Three Tunnels Needed.
For several miles beyond the Yak
ina river crossing. the north
branch canal will run through a
rough broken country. consisting of
a succession of ridges and deep
gulches. On this section there will he
three tunnels having q total length
of about one mile. with one syphon
crossing the principal gulch. From
here to the end of the north branch
the construction will be comparatively
easy. johnson Gulch will be crossed
by syphon of wooden stave pipe,
and, short distance beyond this,
there will be q tunnel 1000 feet long.
The head of Badger Pocket will be
crossed by another syphon, after
which the canal line follows along a
rough broken hillside to the upper
end Of the Yakima river canyon.
The north branch" includes In
a "a u owAl~
imately 400 lineal feet of tunnel;
$500 lineal feet of concrete-steel
fiume; 1o,700 lineal feet of wooden
stave pipe; $500 lineal feet of wood
en- fumes; 1850 lineal feet of steel
fiume; and 10000 lineal feet of con-
crete lined canal.
On the south branch canal" in ad-
dition to the earth canal there will
be approximately 3.400 lineal feet Of
tunnel; $500 lineal feet of wooden
stsve pipe; $40 feet of wooden fiume:
$500 lineal feet steel fiume; and 49,
goo lineal feet Of concrete lined canal.
Water From Keechelus
The water supply for the district
VIII be from the Yakima river and
from storage in lakes Kachess and
keechelus ON the head waters of the
river. These lakes are. now being
converted into storage reservoirs
through the erection of large storage
dams by the reclamation service.
When completed the former will
have capacity OF $4,000 acre feet
and the latter 100000 acre feet. The
lakes are fed principally by the melt
ing snow in the mountains near the
summit of the Cascade range. The
depths of snowfall frequently arrre-
gates 20 to 80 feet in ono season,
during the periods of high water In
the spring OF the Year. the canal will
De supplied by the surplus waters Of
the Yakima river.

Inc headworks of the Kittitas re-
cianlatioh district canal. popularity
known as the High Line" canal, will
De located about one-haf mile west
Oh the town of Easton, and about
three miles below the lake Kaehess
reservoir Water will be diverted
from the Yakima river at an eleva-
ton of 2,175 feet, by concrete dam
| l5o feet long and so feet high. From
TINS point the main canal follows
oown the south side of the river a
distance OF twenty-siX miles, where it
divides, one branch crossing the Yak
ma river to the north side, and the
| other continuing around the south
side of the valley to Manastash creek.
IRE north branch has a total length
OF about fifty miles, and the south
branch about fourteen miles.
