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.

FLOOD REPORT 2011

FLOOD HISTORY

In the past history Sutlej River had experienced worst historic

floods during September 1988. A total discharge of 5.0 lacs Cusecs was

recorded at Suleimanki Headworks against its designed capacity of 3.25 lac Cfs.

At Islam Headworks recorded total peak discharge was 3.66000 Cfs. At that

time this flood water passed safely through Mailsi Syphon without any damage;

but great pressure was experienced at Empress Railway Bridge Bahawalpur.

Likewise supper flood of 962000 Cfs. was experienced at Panjnad Headworks

during the year 1973 which caused serious damages in Bahawalpur and

Rahimyarkhan Districts.

In the history of Punjab, floods have created heavy damages to

property and infrastructure. The major losses of floods of 1988 and 1992 in

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.

FLOOD REPORT 2011

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

overcome any eventuality in the expected flood 2012. Therefore, it is recommended that:

PC-1 for Rs. 1219.28 Million of flood restoration work namely FloodRestoration Works in Rahimyarkhan Canal Circle already stands submitted to

the Federal Government for approval, which has already been discussed in theCDWP meeting held on 14-10-2011 and was cleared for submission to ECNEC

for approval. It is important that the funds may be allocated / released at the

earliest so that the work be got completed before the ensuing flood 2012.

An amount of Rs. 20.00 Million is long outstanding to be paid by this Zone to theArmy Authorities on account of purchase of flood relief explosive / accessories

for Breaching Sections at Panjnad Headworks. It is appropriate to arrange the

funds at the earliest for making payment to the quarter concerned before onset of

flood season 2012 for avoiding any eventuality during expected floods in future.

Special funds application has already been submitted.
