er. That IL, there is lost 284 horse
power o. account of transmission and
conversion to mechanical energy, or
"a per cen Of the power is lost. In
order to pump $500. 900 gallons per
"a hours from the anO into Raw
Inns. sufficient power will have to be
available to lift So feet against a
total head OF 700 feet using a l6 inch
pipe from the canon to Rawlins. This
will require APT actual horse power.
The plants as designed at the Ok
Bows would have an excess of 1877
horse power when $50 second feet or
ovcr was flowing in the river. How
ever. when the flow dropped to a
minimum of 1876 feet as it has in
some years, there would be about 300
horse power delivered to the canon
| from the combined plants. This
much w would deliver only p
100000 gallons to Rawlins. If a
canon to Rawlins the head pumped
against becomes $50 feet and 1t
would require $40 actual horse now
er to pump the $500. 900 gallons to
Rawlins. There would be sufficient
power to do this when the river was
flowing $50 second feet or more, but
when the river dropped to a minimum
Of 1876 second feet the available
power would pump only 100000
gallons per "a hours.
In brief this second system will be
outlined as follows: The develop
ment of the two OK Rows with all
electrical equipment, the construc-
ton Of a transmission line approx
imately 20 miles in length to the
canon site. the construction Of a
pump house and pumping equipment
similar to the equipment described
in the Big Ok Bow development ex-
cept the turbines are omitted: the
construction Of the pipe line to Raw
Inns as will be described in the canon
%struction Of proper natural filters as
described in the canon development.
In order to operate such a system
rs described last, 1t will require the
following labor based upon zach man
working a 12-hour shift. Two men
at the Upper Ok Bow; one lineman
20 watch the transmission lines and
keen same in order; one man at the
nuwO house: and several ezra men
during the winter months to teep
voter through the tunnels. There
~ill need to be CONSTRUCTED at least
five houses for the operators.
Canon System Development
4 In any water works development It
is an imperative matter to secur as
much concentration as possible in
the system and in the several units
that comprise the system. If q sys-
tenn can be developed that gives
greater concentration and at the
same time cuts operation and main
~tenance costs to the very minimum.

consideration q at a much higher
price.
The development OF such q con-
~centrated system is possible at the
canon site. At the canon there ex-
lists a fine natural dam site whore
rock abutments are found at both
ends Of the dam and where bed rock
Is encountered from 4 to 7 feet be-
llow the river bed.
In the construction Of q dam 30
feet high above normal low water
there is created a reservoir which
~lcovers at maximum high water 1851
acres and at low water 1880 acres.
An actual survey and traverse of the
high water line Of this reservoir was
made so that its surface areA and
capacity might he computed. When
the reservoir is full 1t has q storage

From the actual data relative to
the flow OF the North Platte River
there are periods OF minimum flow
that make the operation of turbines
uncertain. What is actually needed
In order to give consistency and secur-
Idty of service Is a reservoir of the
capacity here set forth. The turbines
which are designed for this canon in
l%stallation require $50 feet Of water
at all times to deliver $500, 900 gall
Ions per "a hours to Rawlins. Regu-
ilation of the stream flow without any
marked change in head is what Is
desired. The periods OF shortage are
not, at present. of long duration.
consequently this reservoir could, by
slightly lowering the gage height in
the reservoir. supply the period Of
shortage. Lowering the reservoir
only one foot would supply. any
probable deficiency in the flow Of the
North Platte River for a period Of
from 7 to IA days. This yimpound-
ing reservoir is an absolute essential
adjunct to the success OF any system
from the North Platte River.
The plan of development of this
canon project is to construct a dam
100 feet high above low water with
oHV leet VI o'eiI'o" icH6lu. ms
dam will be constructed Of mono
Ilithic concrete in which will be used
all the large stones possible to secure
land handle. The base Of the dam Is
Jas feet wide and set ON bed rock.
The dam is of the standard type with
a long apron to prevent underscour.
On the west end of the dam and as
an integral part Of 1t the power house
will be constructed. 1t is 40 feet
wide by 80 fee long and Is designed
of ample size to house the power ma
ehinery for the pumping OF the wa
tier.
