Review Of Water Situation.
We have certain forest reserves
which are presumed to protect our wa
ter supplies. They are far more lin
NEST intelligent analysis we can make.
we will assume the average rainfall
over all the Forest Reserve area is
$50 inches Per annuTl. and in cnm-
paris1n we will also assume l2G inches
Ber annum to be q closer estimate.
Make your own choice as to correct
ness Of either.
Rainfall in gallons per acre per
year at 1870 inches is 2 %hSE't4 gallons,
at $50 inches 1t is 4.SST.771 gallons.

Evidently there is more water
pumped from the artesian sources
than falls on the forest reserves, hence
the balance and surplus must be de-
rived from the remaining 347, 200 acres
lcemIrising the island Of Oahu.
The WaiahoIe Tunnel. s
This tunnel draws its water supply
| from the main forest reserve, The
aaW from the east portal at its great,
est discharge was 46,060.00o gallons
daily. The flow from tho southern
portal was 100000 gallons, but is
reduced to 12,900.0a0 gallons. daily.
The inflow to. the southern section
was so sudden 1t may have been
caused by tapping the eastern source.
As the sections arc but 900 feet apart

Waiahele tunnel is q great an6 costly
experiment, which cannot be duplicat-
led by the territory or the county,
hence urge you to refrain, for the
present, from tunnel or high elevation
boring experiments. .#5

this purpose, and it is Rart OF the

Extension OF Nuuanu Water System.
Reservoir No. AL have been fami-
liar with this reservoir since its in
ception to now.
I It is but two hundred feet in eleVa-
ton above Reservoir No. 8, hence all
arguments in its favor as. a source OF
water power are ill-eonsidered.. J
The nest experienced reservoir me!
in. the territory believe 1t will not re.
tain water above a very moderate
level 1t is admitted it now leaks. If
any experimenting is to be done, con-
I fine it to the return catchment ditch
estimated to cost SS,000.00.
/. The condition of the interior of Res
ervoir No. is quite alarming with
the mud and vegetation as exposed
to contamination unguarded in every
particular. ~.~. -. ..
A suggestion has been made that
the reservoir could be filed several
times yearly by tapping the head wa
tiers of Manoa valley at about the
100 feet level so as to, by tunnels,
deliver it into No. 4.
l directed Mr.. harrison to investi-
gate and his report is submitted here
with. 1t will be a surprise to know
the annual run off averages only $50
million gallons or less than one and
a half millions daily, and that 10000
feet CT tunnel would be necessary be-
sides other heavy expense,
l am opposed to the expenditure of
$33,50000 to divert water that natu-
rally should flow into Reservoirs No.
3 and No. 2, that it may be stored in
doubtful No. and furnish unreliable
power.
Reservoirs No. / and No. 2.-These
can be materially enlarged and water
