Capt. Gaillard, the engineer officer in
cnarge OF the Washington aqueduct and
accessories, reports to the chief of cngi-
neers that during the month Of March the
heisnt OF water at the gauge at Great
Fails varied between 1850 feet and 1906
1eet. Seventeen days out of the thirty-one
days of the month the water at Great
Falls and at the effiuent gate of the dis
tnDuting reservoir was very turbid. At the
last-named point, where it enters the main.
II was turbid for six days, slightly turbid
Tor three days. and clear for the remaining
nVe days. There was very little change in
the clearness of the water between Its en-
Try into the receiving reservoir and its dis
cnarge into the mains.
Repairs Of the Conduit road were con-
tlnued during the month. Twenty-Five Gu
Die yards of blue stone were hauled from
FOUNDRY branch and placed on the road
Inc stone crusher and engines were set
up in order to crush flint stone for the re-
pairs or the road, and three hundred and
nIty cubic yards of crushed stone were
placed thereon. Capt. Gaillard says that
the work Of crushing the flint stone and re-
pairing the Conduit road will be continued
during the present month.
Preparations are being made for the re-
SUMPTION OF work of raising the height of
the body of the dam at Great Falls, in or
ger to increase the water supply Of Wash
ington. which was suspended for the win
Ter December IA. Up to the close of last
stone and fifty cubic yards of rfprap had
been brought by boat from Seneca to Great
rams. and tracks had also been relaid and
derrfcks set up on the Maryland shore
stone Will be laid on the dam as soon as
the stage of the river permits With the
approval of the chief Of engineers. a con-
tract has been made with Asa B. Cook of
ieter5burg, Va. for furnishing about LOO
fpnn rcf1
cubic yards Of coping for use in raising the
body Of the dam.
The removal Of accumulated deposits IN
.ne CONDUIT was continued during the
inohIn' ana good progress was made. On
the Great Falls division the work has been
completed from the gate house at Great
Falls to point between man. holes % and
a. The work on the Dalecarlia division
has been completed from the receiving
reservoir to man-hole 33. The total dis
tance cleaned on both divisions was 5g53
feet, and the amount Of sediment removed
was l;oo4 cubic yardss The total length Of
feet. -'''
During the progress Of this work a num-
Der OF longitudinal cracks were discovered
IN the conduit, a small crack in top of each
over cuivert 16, about 40 feet long, and a
small crack in top of arch Of culvert II
about 100 feet long. Thirty eight days Ia
Dor has been devoted to cleaning out the
deposit Of mud in the bottom Of the Ches-
NO. !, which deposit was caused by the
necessary opening of the waste gates Of
re conduit for the removal Of deposits.
ne break which occurred, in the by-con-
duit around the Dalecarlia reservoir in
July last has been almost entirely repaired
A Golfer dam was constructed around the
broken section in eighteen feet Of water
and repairs were made with Brick and ce-
ment. The break was about fifteen feet in
length and five feet in height. To give ad-
ditional strength to the repairs a concrete
retaining wall. thirty-flve feet long and
80 feet thick, was constructed between the
by-conduit and the reservoir
