FLOOD REPORT 2011
EXECUTIVE SUMMERY
The flood 2010 was unprecedented and extra ordinary known
history in the Indus River System and flood peaks were for in excess of the
recorded historical floods. In Irrigation Zone Bahawalpur, during flood 2010
the highest gauge of 14.6 feet was recorded against 12.30 Lac Cfs discharge at
Chachran on 07-08-2010. While the river was in action, the vulnerable sites
where the erosive action of exceptionally high flood in River Indus was
experienced was personally inspected by the Chief Engineer, Irrigation
Bahawalpur and references were immediately made to Government for allowing
to take up the works under para 2.89 of PWD Code and the same were got
completed by the hectic efforts of Irrigation Engineers within the
stipulated period.
Drawing upon the lessons of flood 2010, the strategies for
improving flood management include establishment of new bench marks on the
basis of recorded highest flood levels. Furthermore, during the emergency at
large scale level, lack of leadership and coordination at local level was quite
apparent in District and Tehsil Administration System. Planning for improving
flood management on new bench marks was revised by adopting Standard
Operating Procedures (SOPs) to combat with any unpleasant situation for the
flood 2011. Standard Operating Procedures (SOPs) for flood management were
prepared for individual structure keeping in view the identified weak areas /
hotspots. Contingency plans were also got prepared which indicate the location
of infrastructures, flood route with special focus on low lying areas and
villages / towns to be affected.

FLOOD REPORT 2011
INTRODUCTION
Bahawalpur Irrigation Zone covers entire Bahawalpur Civil
Division. It operates Suleimanki Headworks, Islam Headworks and Panjnad
Headworks of Sutlej Valley Project and irrigates the entire area of this Zone
through different canal systems.
Since operation of Water Treaty between the two countries i.e Indo-
Pak, river Sutlej upstream Suleimanki Headworks has gone with its totalsupply to India. All the above three Headworks have been linked by means of
Link Canals emanating from Mangla and Tarbala Dams.
Left Bank of River Sutlej from Suleimanki to Panjnad, Left Bank of
River Chenab from Panjnad to Kot Mithan (Junction of River Chenab with
Indus) and the Left bank of River Indus from Kot Mithan to Guddu Barrage
face Bahawalpur Civil Division and spills / erosion from these rivers become
the concern of this Zone. In addition water from old Hakra River after entry
into Pakistan Border near Walhar in Fortabbas Tehsil also becomes concern of
Bahawalpur Civil Division.

CONCLUSION
In the light of lessons learnt during the super flood 2010 and identifying the
weakness and deficiencies in the existing system of flood planning and management SOPs were
revised by making Flood Fighting Plans on new format. By implementing valuable suggestions
and recommendations of the Punjab Flood Enquiry Tribunal 2010, the flood management was
considerably improved, resulting in saving the lives and properties in flood zone areas.

RECOMMENDATIONS
Although Rivers Sutlej, Channab and Indus remained silent in Irrigation Zone,
Bahawalpur during flood season 2011 yet necessary measures are important to be adopted to
