Vffl. SUPPLEMENTARY ZNTORMATION

(1) Constructional features

(2) Changes introduced in the plans of
the dam and in the method of carry*
ing out the work

Materials for masonry, as stone,
mortar, etc. were*taken by tippers
with motive power and the work was
executed departmentally. Earth
was carried by tippers and the
work was done under piece work
agencies.

The composite dam between Ch. 53
and 58 was replaced by an earthen
Dam, 8 feet top width and 2 to 1
earthen slopes and 1J to 1 revetment
slopes.

The top width of the earth backing to
main dam was re hiced fro T\ 15 to
10 feet.

Sanctioned proposal was for weirs 950
feet and 785 feet respectively at Left
and Eight flanks discharging with a
head of 5 feet. The weir at right
flank was abandoned due to bad
founds and 3 new weirs at left flank
were built. The length of weirs
built at left flank are 120 feet, 170
feet and 90 feet. The head over
the crest was raised from 5 feet to
6 feet. The length of 950 feet weir
was curtailed by 10 feel.

The sanctioned design of both right
flank and left flank sluices were
changed. The ventand shutters at
right flank are the same as sanc-
tioned while at left flank 2 vents,
4' X 5' were provided instead of 3
vents, 4' X 5'.

It was raised by one foot above the
of the dam.
