History of (KBD) Water Divided Nation

1. This Treaty was further interpreted by the pakistan and a new water distribution formula was proposed for the rights to use the Indus water. Accordingly, two dams, Mangla and Tarbela were built to compensate the loss of water transferred to India. Although, the proposed formula was considered as a violation of the legal water rights by few stakeholders, particularly from Sindh, it was mutually agreed and singed by distribution conflict between the provinces, Later, to solve the water distribution conflict between the provinces, the Indus River System Authority  (IRSA) was established, acting as a federal body. Despite the formulation of IRSA, provinces are still arguing on their water rights with IRSA acting as a hopeless spectator.
   
2.  Further, Sindh argues it requires a constant flow of water down the Indus into the Arabian sea. this flow of water keeps the seawater from intruding mainland. Seawater intrusion can turn a wide area of Sindh into an arid saline desert and can destroy coastal mangroves of Sindh. Sindhis also oppose construction of any dam on Indus, Looking at the previous instances of damming the Indus and condequently decreasing in water flow, which would further restrain the water storage capacity of wetlands like Haleji, Keenjhar and Manchar Lakes in the Sindh province. google
3.  On the other hand, to the allegations by Sindh about the theft oh water and Mangla were built to benefit punjab, the latter defends its case by stating that their is no evidence to this. And both dams were built under the Indus Water Treaty signed by the Government of pakistan and not punjab mainly to replace water lost due to the loss of its three eastern rivers Rani, Sutlej and Bias, that were given to India under the Treaty. Further, it argues that since Mangla dam could not meet the requirements of tthe punjab, Tarbela dam was built.
