IMPROVEMENT OF CHANEL.
The channel of the bayou may be
fmproved as follows: From the north
hne OF Washington county to the
south end of Fish Lake, a distance
of about II IL miles the percent
channel is sufficiently large. and
OF about II I-2 miles. tire prehent
IN good condition The only exca-
vation required for this section will
be about 500 feet cutoff at the upper
end of the lake. The channel below
the lake will require enlarging at
some points and Strengthening by
cutting off bends and cleaning out
the chanel where it is obstruc.ed
Beginning at the outlet of Fish Lake,
the channel deepcns sufficiently to
lower the grade line q feet This can
be done by deepening the Original
ichaTnel as far south as section
I7-Iz-7, where the grade OF the pres
ent channel will be intercepted. the
channel from Fish Lake to the Red
Bridge near the centfr of section 81

the present channel may be clean

posed will involve the construction OF

In discussing this feature of tht
drainage we may divide the basin
ipto two sctions, the upper lying
above section 2S-I7-7 and compris-
ing 10000 acres, and the lower
lying between this line and Swan
Lake having an area of $1,000 acres
