manent hoist somewhat different
method should be used in raising the
fish, the above temporary makesh;ft
being employed because it was cheap
and easily handled, and answered the
purpose sought at this time.
"The Condit dam was built about
1911 and is about ESQ feet wide at
the top. Owing to the shape of the
canyon at this place the lower part
is only about 1854 feet in width. The
top of the dam is about 12l feet
from the ordinary water Just below
! the dsm and on the east side is an
overhanging rock LEDGE, the top of
which is 70 feet from the surface of
the dam, A line dropped straight
down from break in this ledge
would touch the upper side of lit
tie bay cutting into the shores of the
pool This little bay had been partly
excavated by the workmen who had
built the fishway { installed some
time after the dam was built and
which was later removed after the
company and L. H. Darwin, then
Washington district commissioner
had come to an agreement for its re-
moval.
| Large Box Constructed
"As it would have been impossible
to devise any apparatus competent
enough to gather fish swimming free
ly in the pool at the foot of the dam
(this was somewhat circular, about
$50 feet in diameter and about IL feet
in depth at the deepest place at the
time the experiments were carried
on), a large box was built on the
shore with the following shape and
dimensions: Face, 10 feet in width;
side width at bottom, 8 3-4 feet; side
width at top. IL feet; depth, IL
feet.
i ut was made especially strong to
withstand the pressure from the
water to be inclosed in it, and then
was launched into the water of the
little square cove and held there be-
tween two large logs which had been
bolted to the rocks on opposite sides
Of the cove and held down here by
being fastened to these and to 6x6
inch beams laid crosswise. In the for
ward end of this box spillway was
constructed, the sill being about one
foot above the water level. This
spillway was made quite deep, SO
that if the water of the pool should
rise above the sill Of the spillway
the latter could be raised by putting
in splash boards or mailing cross
pieces on.
Box Like Old Fishway
"The idea OF this box was that OF
the entrance to an old-style fishway
and was put in at the spot described
and because the entrance of the ole
fishway had been here, and the testi-
rnony of those who remembered il
was that the same would happen with
this box.
"The hoist rails were so arranged
as to run down to the bottom of this
box, the back of it being shaped to
fit the slope Of the rails, and the size
Of the basket was such that when ii
got to the bottom of the railway
which would be the bottom of the
box-it would be about Is inches from
the bottom, while the clearance on
the. front and sides would be Is
inches.
GAS the idea was to induce the fish
to Jump from the pool into the box
where they could be picked up by the
basket, it was necessary to have
considerable volume of water coming
out of the spillway. In order to- &C
complish this flune was built from
the face of the sloping dam to tn
; box, and the amount of water thu
; entered could be regulated by rud
, gates in the flume.st
: Backet Picks Up Fish
5 "In operating the device the baske
, would be lowered down the hoist un
5 til it came to a rest in the water O
i the box about is inches from the bot
: tom. 1t would be allowed to remai
here for varying, periods, from one t
rs minutes, then hauled up to the to-
of the hoist, picking up what fish
could on the upward journey.
"The basket rested on two sets G
!, axles and pulleys, each Independent
A of the other. Upon nearing the to
5 the forward set continued straight u
' the hoist, but the after set, upon whic
3 the basket rested, was run off upo
+. an inverted cresent-shaped trac
J which caused the basket to slowl
e tip backwards and when it reache
certain elevation the fish slide OF
: of the basket into the receiving tan
j previously described"
! About 70 salmon, procured at tn
e United States bureau of fisherie
: station on the White Salmon rivel
were transported to the dam by au
y tomobile for the experiment and re
y leased in a corral at the base, an
the results were said to have bee
n successful enough to justify the opir
: ion that the plan would be practice
t under favorable conditions with pei
manent apparatus.
!, Following the completion Of the es
!, pertinent the device was dismantle
- and stored away. 1T will be installe
again within few months durin
the steelhead trout run, when it
