Reservations of Sindh
Sindhis believe that KBD left bank canal will divert the waters of Indus to Rasul-Qadirabad sector in the upper reaches of Punjab, and the whole of River Indus waters will be left to cater to the needs of Punjab only, whenever their is shortage of water in Jehlum, or in the eventuality of India appropriating all the waters of Jehlum, or Chenab or both
Sindh, which is a lower riparian of River Indus, has constantly felt threatened by Punjab and has bitterly disputed the figures of water availability advanced by WAPDA, citing legal, economic, ecological, geomorphologic and many other reasons for opposing KBD.
From the past experience of the operation of Taunsa-Punjnad and Chashma-Jehlum canal, people in Sindh perceive that Punjab plans to allow the civil works or the canal system to be constructed as projects of national survival and run the surplus water for a few years to establish precedence and develop water users, who will then apply pressure to keep the water supply running. Later, when the water rights are well established in Punjab, they can force the lower riparian (or don’t even ask) to accept the fait accompli and keep the water supply running since the tap is in the hands of the upper riparian.
Therefore, Sindh’s strongly opposes the construction of KBD.
