thus:I The stem is parallel with the
/ line of the dam.
This cut win be about fifty feet deep
and thirty feet wide at the top, sloping
| slightly toward the bottom 1t will re-
quire the cutting away of $4,000 square
| yards of rock At the entrance to this
\ sluiceway will be the gate house which
will regulate the flow of the water. Fur
ther to the right bywash will be CON
| structed and no water Will be allowed to
How over the dam.
The loose rock that is being carted out
OF the cut is being dumped on the banks
| OF the river, ana as soon as the cults COM
pleted the dump will be enlarged to form
/ q Golfer dam to turn the stream into the
| cut while the dam is being constructed.
The main dam will be a very substan-
tial affair. The earth will be excavated
to the depth of thirty feet or more, till
the ledge of solid rock is reached and a
wall of solid masonry, between six hum
dred and seven hundred feet long, VIII
be built on that to a height of forty-five
or fifty feet above the present
level, or total height Of seventy-tive or
eighty feet This wall will be eight feet
wide at the bottom and five feet at the
top. When it is completed earth will be
dumped in at both sides and sioped so that
a transverse view would show width of
276 feet at the bottom and twenty feet at
the top. The water side of the dam will
be paved with rock and the other side will
be covered with loan and soWn with grass
seed.
THE CLINTON BROOK RESERVOIR.
The site OF the storage reservoir is on
Clinton Brook, about three miles in an
easterly direction from the Oak Ridge
reservoir. This is a natural valley of II
regular shape about one and three-quarter
miles long and a mile wide in the widest
part. Three prongs of the valley extend
to the north and east between the hills.
IfaF.s ft1a
slopes are wooded and covered with laurel
and oak brush. The Clinton Brook,
tributary of the Pequannock River, runs
through the valley, and here and there
along its course is joined by riyulet OF
sparkling water, dashing down from the
hillside. Hanks pond, an almost circular
body OF beautifully clear water, a hail
mile or more in diameter. will be one OF
the sources of supply.
The two reservoirs will cover about $50
acres of land, and much of it has been
used for farming purposes. In purchas-
ing the property the company has ac-
Quired from TWENTY-FIVE to thirty farm
houses, with their barns and other build
ings. These were vacated by their occu-
pants on April l, and many of them are
now occupied by employees of the COM
pany. A large proportion OF the build
ings Will eventually have to be torn
down. as they are within the bounds set
for the reservoirs.
Surveyors have been at work several
months at Clinton and have not yet fin
ished their work. The real work of con-
structing the reservoir was not begun I'M
til Wednesday, a few hours before the
reporter reached there, when a
score of men were set at work cutting
brushwood and telling trees on the site
for the dam. A machine was at work on
the hill boring through the soil TO find
the solid rock on which the dam will be
built. The dam will be located short
distance above the ruins of the old Gin
ton iron furnace. The plan of construc-
tlon Tor this dam has not been completed
yet, but the dam will be about 1000 feet
long and of the same height as the Oak
Ridge dam The water area in this res
ervoir will be about the same as in the
other. The Warwick turnpike will be
submerged for considerable distance,
and two new roads will be constructed
by the company, one on either side OF the
reservoir.
THE GREAT WATERSHED.
The entire watershed from which the
reservoirs will be supplied with water is
about sixty-five square miles in extent.
The streams from tWenty-six square miles
will flow into the Oak Ridge reservoir,
and the rest will run into the Clinton res
ervoir. There are no factories or villages
within this region, and, judging from APP
pearances, there never will be, as a more
stony and hill country can scarcely be con-
ceived of.
The water from both reservoirs will
How through the natural channels and
meet at Newfoundland, two miles below
the Clinton dam and three miles below
Oak Ridge. 1t is possible that the two
storage houses will be connected, but
that has not been determined by the en-
gineers.
From Newfoundland to the reservoir at
xxyh fi1ff otror 1,o1f
the distance is about four miles. The
stream flows down over steep and
rocky bed, and the waters tumble and
hurry from rock to rock, in way that
makes one thirsty to look at 10. The in
take will be 400 feet below the Clinton
reservoir and $50 feet below the one at
Oak Ridge, The intake will be about 600
feet above sea level, the reservoir at Oak
Ridge being $50 feet and the Clinton res
ervoir 600. These reservoirs will hold
supply of water sufficient to furnish
100000 gallons day for three or four
months.
The lower reservoir, situated at Ma
copin, will be about a half of a mile
long by a quarter of mile wide
The dam will be built of stone. Little work
has been done there yet, excepting
to cut down and clear away the brush
with which the valley was covered.
gatehouse, with all the necessary appar-
atus for screening the water, will be built
There will be three sets of screens besides
a grating.
The pipe line from there to Newark will
be twenty-eight miles long, and the ex-
pense of the construction of this will be
half the cost of the works. Four-foot iron
pipes will be laid two feet under ground
TO protect the water from extremes of
heat and cold From the point where the
supply will be divided, at or near the city
line, the pipes will be three feet in diane
ter One branch will convey the water to
the Belleville pumping station to enter
the other will be built to connect with the
reservoir on South Orange avenue.
