Railways to operate breaching section on September 14, 2014. After
operation of breaching section maximum 78000 cusecs discharge passed
through the section. It remained operative till September 20, 2014.

2010 Flood
An Exceptionally High Flood was witnessed in August 2010 with a discharge
of 1085601 cusecs downstream at Taunsa Barrage. The duration of flood
remained for the period of about 22 days. The heavy pressure of flood was
particularly experienced on left side leading to the breach of Left Marginal
Bund of Taunsa Barrage. The flood water flowed freely on the country slope
and inundated vast areas of Kot Addu, Sinawan, Mehmoodkot, Gurmani,
Qasba Gujrat and Ghazi Ghat Town. A relief cut at RD: 125800/L
Muzaffargarh Canal was made to release and divert flood water into Chenab
River. The pressure of flood water was so severe that Muzaffargarh Canal got
breached at 12 points. All in all, the 2010 floods caused unprecedented
damage to public as well as private properties and infrastructure.
