Ndsik and Ahmednagar Irrigation District.
The construction of the masonry dam at Chankapur, in the Kalvan Taluka of the Nasik
District, to store water for the Girna Left Bank Canal as well as for the extension of the
irrigation under the existing bandharas or weirs on the Girna River, was completed by the
end of March 1910 . The erection of the waste weir gates was then commenced. The masonrv
w ork for the waste weirs was nearly completed. Fifteen gate frames were fixed in position
an d all the counter-weights conveyed to the vicinity of their chambers. The northern embank-
ment was nearly finished. I he expenditure on these works was Rs. 48,873 during the year.
Water was stored to the level of the weir, R. L. 159 - 00 , and was let out from the tank from
18 th December 1910 for irrigation on the Girna Left Bank Canal. It also supplemented
the supply to the existing bandharas on the Girna River and augmented the storage of the
Jamda Canals in the East Khandesh District. The storage this year was in excess of the
requirements owing to the copious rainfall and the only partial development of the Girna
Leif Bank Canal, the extension of which is under consideration.
The expenditure during the year on constructing distributaries and water courses on the
Girna Left Bank Canal was Rs. 19 , 464 . The total length of the distributaries constructed was
5-21 miles. The work of excavating water courses to conduct water to every field is in progress.
Goddveri Canals Project.
Darna Dam.—The. construction of the masonry dam. for the storage reservoir on the River
Darna near Igacpuri in the Nasik District was in progress. By the end of the season the
average height to which the dam, which is over a mile long, had been raised was R. L. 1864 - 00 ,
or only 11 feet below the top, and it was expected that by the end of the working season the level
reached would be within 6 feet of the finished height. Considerable progress was also made
with the waste weirs. The acquisition of the lands to be submerged above the dam made crood
progress and it is expected will be finished before the end of the working season. The Ghoti-
Ban and Sinnar Road diversions along short length of these roads to be submerged bv the tank
water, were in progress.
Pick-up-Weir at Nandur Madhmeshwar. —The masonry of the crest of the weir was
practically completed by the end of March 1911 , and the weir is now in use and the few items
remaining should be entirely finished by the end of the working season. The land acquisition
work is practically complete with the exception of some difficult cases, and the rebuildino-
of the small public buildings, such as schools and dharmashallas, to replace those in villages
submerged is in progress.
Goddveri Canals. —The first 27 miles of the Godaveri Right Bank Canal with its distribu-
taries and water courses were completed and water let into the canal. Excavation up to mile
62 is practically complete, embankment is still in progress at several places and nearing comple
tion. The distributaries in the length from mile 33 to 62 are also under construction. A
bungalow at Ranjangaon has been built and that at Chitali was in progress.
Excavation along the whole length of the Godaveri Left Bank Canal was practically
completed ; embankment was still in progress at several places. The survey of the distributaries
for this canal up to 16 ^ miles is complete and the detailed estimates have been sanctioned.
Bungalows at Mahalkheda and Padhegaon were in progress.
The expenditure during the year on the Godaveri works was as under:—

Bhandardara Dam. —'The foundations of the dam were excavated almost entirely ; only a
sma length remained to be uncovered on the Left Bank. The foundations show excellent hard
