Damming and Diking Depot.

mere mas Deen considerable talk pro
and con regarding tho matter oil diking
Depot slongh from Mr.. Grady's north
line to the head of tide on Depot slough
Big Beaver and Little Beaver.
There we're two propositions to be
considered. The first was continuous
line of dixie on each side of the above
streams to head of tide,
The second was to place dixie and
dam across Depot slough near Grady's
north line.
The first proposition involved the
binding of eleven miles, or nearly so,
OF continuous dixie. Now in IL miles
there are $500 linear rods of line. Now
the lowest figure at which a dixie could
be constructed that would properly
protect1he land enclosed would cost.
roughly s3 per linear rod requiring
Tor the entire dixie the expenditure Of
SlO,560, and adding to this the value of
the land needed for right-of.wav-3C
acres at $50 per acre gives an additional
$500, or total of $l2O6O-for which
sum the whole OF the lands so protected
could undoubtedly be bought. This
proposition then. on the face of it, the
viewers decided was unjust to the prop
erty owners affected.
The second proposition was then
taken up. A site for dixie and dam
across Depot slough was then selected
and located and the engineer in charge
was directed to make careful survev
of same, draw plans, maps and dia-
grams illustrating the proposition and
make proper estimates of cost of same,
and TO endeavor 10 meet the two serious
objections that at once arose against
the placing of dam as proposed across
Depot slough at the place selected.
The first and most serious objection
came from the obstruction of "logging
stream" which, under the laws of Or
egon, is held as inviolable as any other
public highway. This matter the en-
glneer in charge has met by the con-
struction of a log chute 81 feet by 915
feet in the clear, provided with both
tide pressure and spill-dam gates that
provide for the easy passage of logs up
to the diameter of feet, and which
also provides Il most spacious basin in
the bed of the slough. unaffected by
tide or current, where logs can be held
indefinitely and can be quickly and
readily taken out by closing one or
more of the three tide gates.
The engineer feels that this one feat
nre alone is almost worth the whole
cost of the dam to the loggers alone.
The second objection, and serious
one, was the question whether,the flow
OF storm water from aboye-from De-
pot, the two Beavers and a few small
creeks-would not so bank up on the
dam as to cause more serious damage
than the normal flow of the tide. This
necessitated on the part of the engi-
neer careful survey-frst of the var.
ious eams-Depot, the two Beavers
and Two other small creeks at head of
tide-to to ascertain the amount of storm
water which each could deliver at the
dam in the period of say six hours.
Second, to survey the basin contained
in the empty bed of Depot and the
Beavers from head of tide to dam and |
calculate on conservative estimate |
the number of cubic feet of water that |
this basin would contain as capacity for |
disposition of storm waters. This ca
paclty was ascertained to be equal to |
1900, 900 cubic feet. This second diff.
Guilty was met by the engineer by the
construction in the dam proper of three
tide gates, each having an area in the
clear of lx12 or total area of DISCHARGE
OF D feet by IL feet -equaling 36 square
feet, or in itself equal to the whole
flow OF Depot in storm food. Leaving
the vast capacity of the basin of the
slough-7 500, 900 cubic feet-to absorb
the two Beavers and other storm flow.
winch 1t Is ample to do for "a hours, in
stead of six hours calculated upon.
These tide gates are so placed that
there will only be period of IL hours
during high tide when they will not be
discharging. Therefore the engineer
considers that this second objection is
amply provided for. In the estimates
made, the last foot of earth, the last
foot of lumber, the last nail or bolt has
been provided for; the cost of labor
and material, of excavation aud en-
bankment necessary, has been shown,
and the figures are reliable and con.
servative, and the engineer invites the
closest criticism and inspection by those
interestedH-especially loggers-to the
