advantage of a greater storage, but the former has, with the Godavari and Kadwa rivers a
much larger catchment area from which it draws its supplies. A special feature of the

-mrl CB"i v yP': e P arat iop have been made for the construction of a new dam, a mile long Nira Right Bank
j \wu-^ ° fee L he present graceful structure, 100 feet high, designed and built Canal —Lake
by Mr. J E. Whiting, M.A., M.LC.E. The original intention was to build the new dam over Whitin gdam.
e exis ing one, but that proposal has been abandoned for various reasons and an entirely
new dam is to be constructed, at a safe distance from the old one. A length of 1,740 feet of
ve excavation has been finally passed for foundations, another 1,380 feet will soon be ready
while in 1,200 feet of the river portion the presence of red rock is proving troublesome but '*
sound rock is available below it. About 1,000 feet length of the new dam lies inside the
existing tank and work can only be done there during half of the year.
T he red rock found in the river, though used for foundations in parts of the existino-
dam is not strong enough for the pressures in the deepest part of the new high dam, hence
the loundations must be taken do.wn below this material in the river portion.
( The irn gation water is being carried over the new foundation trench by means of a
sjeel pipe 5J feet diameter supported on masonry pillars and connected to three 30-inch
s uices laid in the old dam. The 15 large undersluices of the old dam, each 4'x 8' in size,
e purpose of which was to keep the tank clear from silt by the discharge of the first floods
o e monsoon, cannot be used again until the new dam has been founded and brought up
above ground level in the river portion.
The machinery on the works is to be driven by electricity produced by water power
rom the existing dam. I he preparation of this plant has been somewhat retarded by the
var in Europe. The war has also prevented the adoption of an aerial ropeway for the trans
port o lime and this work will therefore be done by bullock carts. Masonry has been com
menced on a short length of the dam. The expenditure of the year was 12 lakhs One lakh is equal to one hundred thousand rupees of rupees Indian silver coin also widely used in the Persian Gulf. .
About 3| lakhs One lakh is equal to one hundred thousand rupees of rupees Indian silver coin also widely used in the Persian Gulf. has been spent on foundations of the dam, otherwise the
expenditure of about 17 lakhs One lakh is equal to one hundred thousand rupees of rupees Indian silver coin also widely used in the Persian Gulf. up to date is for machinery, water-supply, all kinds
0 , Wings, kflns and lime supply, communications and materials at site. The cost of the
whole dam will be about 100 lakhs One lakh is equal to one hundred thousand rupees of rupees Indian silver coin also widely used in the Persian Gulf. .
While the construction of the Bhatghar dam is in charge of one Executive Engineer Canal.
p 1 .the usual staff, the Nira Right Bank Canal has been entrusted to two separate Executive
"Rgmeers who spent over 18 lakhs One lakh is equal to one hundred thousand rupees of rupees Indian silver coin also widely used in the Persian Gulf. during the year, continuing the excavation and
