This canal worked satisfactorily throughout the inundation. The works provided for ’

canal continues to work satisfactorily.
The improvements to this canal estimated to cost about 1| Idkhs have been compW i
without any excess over the estimate. It worked very satisfactorily considering the p &
nature of the inundation. 1 0l '
This canal has once more fallen upon evil days, as the river has cut into the feeder ehapn ]
which previously gave such an excellent supply, and, owing to the erosion, much silt e ’i
brushwood was carried into the canal. An attempt was made in May to remove a silt dep 0 I1 ‘i
in a length of about 1,200 feet at the mouth by means of the dredger Mudlark, but the dred Sl
could not remove the clayey deposit. The first rush of water into the canal, however, remoy 6 )
this silt in a few hours. The Executive Engineer reports that at two places in the llth
the canal has deepened its channel by scour, while the width has been decreased by heavy s ju
deposits at the sides. The supply throughout the season was very poor and never reached
full supply level. Rotation was freely resorted to in order to distribute the water f a i r ]
amongst the different branches. The sum of about Rs. 10,700 was spent on constructing
masonry Kurria heads in order to improve the distribution of the water.

This very successful canal gave an excellent supply throughout '.the season in spite of
poor inundation.
The construction of the Choi branch ex-mile 6 was completed with the exception of the
distributaries and the new head regulator for the main canal was commenced. On the whole
the canal worked very well, but the extra supply had to be curtailed owing to the injury by
scour, which had been caused in previous years, by passing down more water than the canal i$
adapted to carry.. A more equitable distribution of the water in the lower reaches was effected
by reducing the sizes of some of the Kurria heads, and the tail portion received a late supply
for rabi. ^
Two small distributaries costing about Rs. 8,500 each were completed and seven other
were commenced, the object of these is to regulate the supply and check waste. The canal
worked well throughout the inundation. The project for improving this canal has been kept
m abeyance, as it will probably be included in the proposed Right Bank Canal System.
The Chur mouth was not opened until the 14th June, owing to the new road brid« , e in the
10th mile not haying been completed. It worked as well as could be expected considerino-the
very low inundation. The Eordwah mouth was opened on the 1st June and worked'’very
satisfactorily. The area cultivated on the GUv will probably be considerably less than usual.
The widening of the New Akil mouth, estimated to cost Rs. 1,68,060, has now been
completed. This canal and its branches worked remarkably well considering the low inunda
tion, but the area cultivated is probably considerably less than usual. This is principally due
to damage done by the heavy rain m June which flooded a large area (about 20 debs) of fertile
land and did a considerable amount of injury m other ways.
In the ShiUrpur Canals District, the head regulators in the new loop bund for the Chili
and Garang Canals were practically completed at a cost of Rs. 8,390 each, and in the KanSchi
Distnct, four small regulators were constructed at a total cost of Rs. 7,913. The principal
canals m the Karachi District, a. r, Ae Knyari, Baghar, Kalri, Laikpur, Satta Khanto and
w01 T ke ^, considering the poor inundation, nevertheless the crops suffered
e tensively.. In the Rpght Bank Division, about one-tenth only of the cultivation is by lift;
whereas, for the Left Bank, the proportion is about one-third, consequently the loss due to a
poor inundation is greater on the Right than in the Left Bank Division. 7

the tront bund was carried away and the flood water passed through the incomolete new loop.
This occurred on the 19th of August, but as the river fell, the iuumTation bring a very bid oi,
no serious damage was done. It is estimated that the revenue which will be derived^from the
flooded land will censiderab y exceed the loss due to the destruction of kharif clops. After
the inundation arrangements were made to complete this work and to increase the height by
two feet, also to construct a loop from 4/3 to 6. The progress on theso works and also on the
construction of a new loop (Abad Loop) from mile 19/6 to 22/3 was satisfactory.
The expenditure during the year on the above four loops was about Rs. 2,67,000.
