Moran, Wyoming, July ga
site of the permanent dam at the
foot of Jackson Lake has finally
been selected; operations are under
way, and the work will be completed
the latter part of next year unless
unforeseen obstacles are encountered.
During the past two years the
Reclamation Service has worked dill
gently prospecting for suitable loca-
ton, and have at last decided to build
the dam Immediately above the tenn
porary one at the foot of the lake.
The above information, together
with the following details, has been
very kindly furnished by Mr.. Francis
T. Crowa, the engineer in charge of
the project:
AS an initiative step, force Of
men are now at work on the west
side of the lake, getting out timbers
for the erection of saw-mill which
is scheduled for completion about
August GOTH The machinery, con-
sisting of carriage and saws, a As
horse power engine, and two 20
horse power boilers were shipped
from Chicago July 14th. A steam
tug will be utilized in transporting
timber to the mill.
Another gang of men are building
telephone line from the damsite to
Ashton. This work will also be rush
ed to completion as rapidly as posi-
BILE.
The road to Ashton, 81 miles in
length, on which a large force Of men
have been at work for two months,
will be completed during the first
week in August This highway which
will cost about 100000, will reduce
the distance from Moran to the rail-
road about So miles.
Freighting of structural material,
mill machinery, cement, ETC., will be
begun just as soon as the roadwork
is finished. About 1, 600 tons of
freight will have to be hauled from
Ashton the bulk of which will be
brought in during the coming fall
and winter.
Two road-houses are under con-
struction; one at Squirrel Meadow,
and one at Cascade Creek, 25 and 81
miles respectively from Ashton. Each
will consist of a kitchen, mess-house
and bunk house, and granary and
stable to house twenty teams.
The dam, 200 feet long, will be
built of reinforced concrete, and it
will require about $500 barrels of
cement to complete the job. The
dixie, 1000 feet in length, will con-
sist of heavy, earth section with
sheet piling and cement core-wall;
the upstream side to be protected by
heavy rip-rap. The total cost of dam
and dixie will be approximately $780,
600.
The permanent structure will be
six feet higher than the temporary
one, and for distance of half mile
the river will be excavated to lower
the water 3 feet below the natural
low-water level. This will give 8 feet
more capacity; but the intention Is to
raise the high-water mark only two
and one-half feet, making an actual
increase of five and one-half feet
above the amount of water that has
been consumed by the present struc-
ture. This vast reservoir will have a.
storage capacity of 10000 acre feet.
In all PROBABILITIES 200 men will be
at work on the project by the third
week of September.
Jackson, 40 miles from here and
80 miles from the railroad, has al
ways considered herself the slot Of
inverse. In the opinion of the
denizens of that hamlet, Moran is a
God-forgotten waste above timber
line where wagon-tramps are some
times obliged to camp at night on
their way to and from the Park; and
where elk sojourn only for short
rest as they wend their way each
autum toward the premival spring
land of the lower Holesrs. But when
Moran can move up on the map to a
little over sixty miles from the rail-
road, and have busy hive of 200
industrial workers within block of
the city hall and post office, the erst-
while metropolis of Jackson's Hole
will be animated as last-year's
birds nest. j. Z. 3.
