WILL Dc nearly ~ miles nearer
to Spokane with the compile
ton of the Omak-Disautel-N Mes
pelem road to the Grand Coulee
dam is shown by the survey of the
state highway eng neers.
The present distance from Omak
to Spokane by way of Mansfield
and the Brewster Coulee Cutoff is
1927 miles and over the Disautel
route now under construction will
be 1854 miles.
The report submitted to John
Duff, district engineer, by G. w.
Nash, engineer of secondary pro-
Jects, shows that the Omak lake road
would cost about 100000 more than
the Disautel road. 1t also shows
that of the 51.54 miles from Omak
through Disautel and Nespelem to
the dam all but 1915 miles has re-
Gently been improved or is either
now under construction or includ-
ed in the budget Of the Indian SER
vice for construction this year.
A serviceable road could soon be
finished if an appropriation could
be secured that would cover the
completion of the remaining 1915
miles of highway.
The state engineers were en-
ployed by the county commission
ers to make the survey.
Both routes are completely cov-
cred in the report. The sections Of
the roads indicated by letters may
be found on the engineers map

Mr.. John Duff
District Engineer I
Wenatchee, Washington
Dear Sir:
wish to submit herewith my
ltemized and sectionized report of
Okanogan County Secondary Road
Project No. Is, performed at the
expense Of the County and with
personnel OF the Highway Depart
ment.
This project includes locations on
the two routes from the Okanogan
Valley to the Grand Coulee Dam.
Addition information Is included
on the sections involved in the two
routes so that the report covers
the entire length of each route.
In this report the two routes
(Omak Lake and Disautel Summit)
have been divided into sections
which are shown on the accom-
panying vicinity map and an esti-
mate OF cost made for each section.
The estimate for Secondary Pro-
ject No. Is is based on actual field
data which accompanies this re-
port. The estimate on the sections
not included in the location project
is based on experience with works
of a similar nature. Secondary
Project No. 10 includes sections BE,
Hi, and Ill as shown on the vtcin-
ity map.
The data for the Disautel route
has been checked by the District
Office and corrected That for
Omak Lake has been checked but
has not passed through the District
Office.
Nothing in this report Is to be
construed as recommendation for
either route but the information
shown is statement of conditions
as they were found to exist.
Following is an explanation of
the sections:
Section ABB
From the point A which is ap-
proXimately nine-hundred feet
north Of the east end of the State
Highway bridge at the Coulee Dam,
to the point B which is the COM
mon point of beginning for the two
routes and Station O. 90 on the
located line, Omak Lake route,
there has been constructed a road
by the United States Indian Ser
vice, 7.12 miles in length, with good
alignment and profile with
twenty-four foot section but with
out surfacing.
Section BIC
This section is the located line
on the Omak Lake route of secon-
Diary project No. 10 and Is 32.777
miles in length. The existing road
on this section is a one-Way earth
road with heavy curvature and
steep grades and is at present dam
gerous to travel.
The maximum curvature on the
new location is ten degrees and the
maximum grade is Tilt per cent.
The estimate of cost is based on
a roadway "a it. from shoulder to
shoulder after placing inches of
ballast and includes inches of
standard base course surfacing and
3 inches of standard top course
surfacing. There are five trestles
included in the project varying in
length from Is #. to 400 #. and in
