PROPOSITION NO. /, UNDER PLAN A..
SUPPLY FROM BOONTON FALLS.
The proposition herewith submitted to
fulfill the requirements of Plan A con-
way River at the head of the water pow
er of the j. Copper Lord estate, at Boon
ton. erecting a masonry dam at an elN
walton of something over 4S0 feet, and all
necessary gate houses and a-ppurtenances
as required by your specifications.
The Rockaway River above this point
has a tributary watershed of 18 square
miles.
The storage requirements under your
specifications for this area are 1858 mill
ions of gallons. This we propose to fur
nish by two storage reservoirs, one in
the Longwood Valley and the other at
Beach Glen.
The first. reservoir, in the Longwood
Valley. will be formed by a dam at a
point about two miles north of the cross
ing of the Delaware, Lackawanna and
Western Railroad.
The bottom of the valley at this point
has an elevation of about $50 feet. The
high water line of the lake proposed to
be formed will be approximately 744 feet.
The low water level, or draught level,
will be at 700 feet.
The tributary drainage area is PA
square miles, which at the maximum
storage allowable under your specifica-
tionS of 175 million gallons Per square
| mile, will give 1920 million gallons. The
actual capcity of this reservoir above
low water level, or draught level. will be
slightly over 1000 million gallons. The
area of the reservoir will be about $50
( acres. Having a length of about four and
one-half miles and an average width
Of about one thousand feet, it's greatest
depth will be ffty-four feet, and the av-
| erage depth about 23 feet; much more
than IS per cent. of the area will be over
| your requirements of eight feet in DEPTH.
The other storage reservoir will be at
Beach Glen. This is a valley extending
north from the main river to the. Hiber-
The dam will be located at the mouth of1
the valley. where the present surface is
about 52 feet above tide. The high waf
ter level in the reservoir formed will ne
541 feet. The low water draught level

greatest depth of wafer at the dam will
be % feet, and the average depth ahouN
Is feet. The proportion of area with less

Of the whole area.
/ The water from storage reservoirs will
flow in the natural channel of the river

take, d single line of 60 inch riveted steel
pipe, with an hydraulic gradient of 7.2i
| feet pen mile. will extend TO the western
side Of Watching Mountains at an ele-
walton of 1896 feet. The water viii be
| carried through the mountain in a tunnel
brick or cement lined, for a distance or

slope Of lL2 feet per mile, or a total fall
of ITO feet, and will Y an area OF ser-s
