The expenditure on maintenance and repairs of the Krishna Canal was Ks, 6,877 and a
sum of R-s. 1,400 was spent in constructing an overbridge on the road from Dndhandi to
ric ^ there w, the Kundal Road Station in order to provide facilities for local traffic. The remaining
'Ucliture nv, works given in the above table were maintained at a total cost of Rs. 12,766.
The Gok4k Canal Storage Reservoir is the only large irrigation work in this Division.
As almost the whole of the storage during the hot weather is required to supply energy
to the Gok^k Mills, irrigation is almost entirely limited to the monsoon and rabi seasons.
The rainfall was good and timely for crops, and consequently only 7,695 acres were irrigated
as compared with 13,389 acres in 1902-1903. The tank overflowed on the 12th June 1903,
and the level of the highest flood recorded during the year was 3*94 feet above the crest of
the weir, the corresponding discharge being calculated at 61,000 cubic feet per second,
which is equivalent to a run-off of 0*09 inch per hour from the catchment of 1,080 square
miles. '
Experiments were made to ascertain the rate of evaporation from the reservoir in the
fair season with results recorded in the following table : —

Worh done by the Superintending Engineer on Special Duty,
The Nira Canal Survey is by far the largest scheme in the Bombay Presidency The name given to each of the three divisions of the territory of the East India Company, and later the British Raj, on the Indian subcontinent. excluding
Sind. The area to be commanded by the proposed Right Bank Canal (probably over 350
miles in length) is a million acres. To supply water for it, four tank sites have been
examined, the two new ones dealt with in the past year being directly above and below Lake
Whiting. The latter will, if constructed, have a high dam at Yir on the site of the existing
pick-up weir for the Left Bank Canal. Further detailed surveys were made for the first
100 miles of the Right Bank Canal, and the preliminary surveys for the extension reached
the 250th mile on the boundary of the Bijapur District. It will be continued through the
Indi and Sindgi tdlukas of Bijapur (passing close to the Sangogi tank site) until it reaches
the Nizam ; s boundary. All the proposed tanks lie in the Bhor State; there is no possibility
of obtaining any useful storage outside the State boundaries.
The Gokak Canal Extension Survey is the next largest scheme. It will command
just under 500,000 acres, nearly half of which is in Native States. With the exception of
a third tank site (at Ajra on the Harankashi) all the field work for this project is completed,
and the designs and estimates will be very shortly submitted to Government. During the
past year the Hadlag tank site has been investigated, and the whole canal with its branches
has been re-surveyed on a higher and more favourable alignment. The total length is
now 80 miles of main canal and 100 miles of branches, exclusive of the distributary
channels.
The first stage of this project is to consist of one tank and 40 miles of canal up to
the Mndhol boundary, commanding 90,000 acres. The complete scheme will require three
tanks, two of which are in Native States and the third will submerge an exceptionally large
area of excellent cultivated land, besides many villages.
