RIVER. AT BooNToN..
The main intake dam will be below
the railroad bridge at Boonton, The
high water level in the intake will be at
elevation 1865, and low water level at $50.
The dam will he of rubble masonry,
intake will have a surface area Of eight
acres and a maximum depth of thirty
feet. The tributary drainage area above
the intake is 118 square miles in extent.
as follows
Rockaway Valley Reservoir will be To-
Gated on Stoney Brook. The dam will
be an earth embankment, with concrete
core wall and will be situated as shown
on the map accompanying. The high
water level of the reservoirs will be at
523 feet elevation, the low water level at
800 and the capacity twelve hundred and
fifty million gallons ,250, 0O0, 0O0. The
area at high water will be 2I6 acres and
Is per cent. of the area will exceed eight
feet depth when full. The maximum
depth will be twenty-seven feet. The
tributary drainage area measures twelve
square miles.
Beach Gler. Storage Reservoir will have
its full water level at 53S feet elevation,
its area being. 7S6 acres. 1t will be drawn
down to $40 feet elevation. It's capacity
will be three thousand two hundred mill
ion 100000, 000 gallons. Eighty. per
cent. of its area will have a depth ex-
ceed1ng eight (S) feet; nearly nail OF IL a
depth of eighteen Q8) feet or over, and
the maximum depth will be twenty-six
(26) feet. The dam will be of rubble ma
sonry and concrete. The bed of the
stream below the wasteway will be pro-
tected with heavy rip-rap. .

sorry and concrete.
Rockaway Valley Reservoir will be
connected with the intake gatehouse by
a steel srivetted pipe, having an internal
diameter of sixty 600 inches and a n.y.
draulic slope of two feet in one thousand
feet. When the Rockaway River is swollen
and turbid the water may be drawn direct
from the Rockaway Valley Reservoir to
supply the city. Usually, when the river
is III in its normal condition, this pipe
will net be used, but the water will be
allowed to flow down the stream from the
reservoir to the intake. This will insure
a supply of clear water at all times.
From the main intake dam there will
be asrivetted steel pipe of sixty-four inch
es least internal diameter leading to Great
Notch. This pipe will have a hydraulic
slope of one in one thousand Q-1,0N).
There will be an overflow provided where
the Pine crosses Hook Mountain, which
will always discharge the water when the
head rises than thehydraulic grade

pressure. The same device will be intro
i duced at Great Notch. From Great
Notch to Jersey City there VIII be a. riv-
