average length of 200 ft; it was suspected that had this not
happened, 193, 000 acre feet of water would have inundated
Ghotki district.
pp) Within Sindh, its declining but sustained flows demolished nearby
secondary Loop Bunds of old Ghauspur, Ghaurghat Bund and B.S.
Feeder Canal Bunds too, to dislocate large populations besides
inundation of the fertile farm-lands.
qq) These bunds had a history of frequent breaches, recorded in the
Sindh Bund Manual but not always necessarily coinciding with
Super floods: e.g. Tori Bund breached in 1904, 1930, 1932, 1942,
1975, 1976 and 1995; old Ghauspur Loop Bund in 1912, 1921,
1924, 1925, 1926, 1927, 1928, and 1929; whereas the GG Bund
breached in 1929, 1935, 1955, 1956 and 1976.
rr) By 10 th August, 1,131,000 cusecs reached Sukkur Barrage with
reduced capacity of 1.1 million cusecs. This barrage was
constructed in 1932 with a designed capacity of 1,500, 000 cusecs
optimum, and at a time when up-country major water reservoirs
under the 1960 Indus Water Treaty were not even in contemplation.
It commands some 7.0 million acres of fertile farm lands including
date-palm orchards in Khairpur through seven canals, three on right
bank and four on left bank with scores of minors and subsidiary
channels and is thus an important source of livelihood.
ss) Further downstream Sukkur Barrage, within Sindh, it took 17 days
for the super floods to reach 1956 vintage Kotri Barrage with
optimum design discharge of 1.0 million cusecs. In 2000, its gates
were revamped and pond level was raised by 2 feet.
tt) On 27 th August, 964, 897 cusecs passed Kotri against previous
highest of 981,000 in 1956.
uu) Against expected travel time of 72-78 hours from Sukkar to Kotri, it
took 336 extra hours.
