lin 1918. by the building of pipe line
with open iointed branches to inter
lcept its flow. Since the amount of
water obtained did not come up to eX-
lpectations another branch was run
out diagonally toward the channel Of
the Umatilla river, which probably
ldraws water from the main underflow
of the Umailla river channel.
Since the construction Of the Thorn
Hollow intake. there has been observ-
ed a lowering of the ground water in
the immediate vicinity. From con-
lsideration of the general situation, we
believe that the Thorn Hollow springs
will continue to give steady, and only
slightly diminished flow in the future,
i but that further development of this
supply will not be possible. The
growth of weeds in these lines was
brought to our attention, and may in
the future necessitate slightly differ
ent type of construction of equal eff
cheney in collecting the water.
Chaplish Springs.
These springs have been utilized
only during the present season. and it
is impossible to tell from surface indi
cations whether or not their possibil-
spring coming into the Umatilla river
north of the railroad tracks and op-
posite Chaplish springs may be found
to come from the same source as the /
water which is now being used. The /
valley of Squaw creek, only a little /
ways above Chaplish springs has been .
suggested as the souEce of these 4
springs. and the connection is very |
possible.
From all these conditions it apepars .
that the possibility of securing very .
largely Increased flow in the vicinity
Of the present Chaplish springs in
takes. is of sufficient weight to justi
fy rather extensive investigations of
this source of supply
SuIIaw Creek.
The collection of all of the under
low of Squaw creek through the con-
.truction of sub-surface dam be-
ween two rock points near the mouth,
mas been proposed. The existence of
live stream in the upper part CT
'Iuaw creek canyon, which disap-
,eais into the heavy gravels near tho
mouth. makes it appear a very fea-
ible source of supply. The use of a
ub-surface dam might prove a prop
+ solution If bed rock We're found at
reasonable depths extending entirely
cross the creek channel, but we be-
icNe that practically all Of the flow
