1T will cause surprise when ii is
known that the waters of Lake Hearst
are merely sort of reserve to be used

supply of water that will be sent to

comes from three sources. First, the
water from the snow that flows down

group of springs about half way be-
tween Lake Hearst and the reservoir,
and third, a running stream which
empues into the gulch about half
mile below the lake. From these three
sources 1t is expected that sufficient
water can be secured to furnish the
city with an abundant supply. Should
these fail, however. there is always the
'oo'o0o,ooo gallons in the lake that are
available.
: The storage system consists practi-
caliy OF three immense reservoirs
counting Lake Hearst as one. Besides
the lake, the new. reservoir has a ca
pacity of 75.000.000 gallons of water
This reservoir. which is the distrib-
utlng reservoir, will have it's water
surface, when filled, 800 feet higher
than the street in front of the Montana
motel and 1t will be 40 feet higher than
the water surface of the old reservoir
The new reservoir is formed by build
ing an earth and masonry dam across
a narrow place in the gulch, and when

excavated from large deposit in the |
vicinity. and it is over 40 feet thick at |
its base and u feet wide at its top. |
Lengthwise through its center will be |
a massive wall of concrete, made from |
the German Portland cement and rest
ing on bedrock, its purpose being to
prevent absolutely the leakage of water
through the embankment. No pipe is
allowed to pass through the embank-
fnent, but in the solid rock, beyond it's
east END, a valve well is excavated in
the solid rock and lined with the best
hard burned brick, An open cut has
oeen made from this to the reservoir
nto which is laid a 24-inch blow off,
,lpe, and the two 14-inch pipes, which

In addition to this there is still the

'obable that pressure greater than
or 50 pounds will ordinarily be put c.

As has probably been observed, pipe L;

streets in the city proper, and rs
on as spring weather takes the frost a

master main will be laid from Nu-

this there will be a general over Ia
