"Indus River System Authority (IRSA)is a federal organizaton. It was established under the IRSA Act of 1992 in the wake of inter-provincial Water Apportionment Accord (WAA) of 1991. The accord apportioned the water among the four provinces. It also established a formula to distribute surplus and scarcity of water. The Accord reqired establishment of an authority that would supervise the terms of the agreement. Hence, IRSA was established in 1992. IRSA consists of 5 members. One representing every province and the Chairman is appointed by the Federal government and according to a presidential order its chairman is required to be a Sindhi also. Its headquarter was shifted to Islamabad from Lahore. In the wake of current water scarcity and other water related problems among the provinces of Pakistan, the Authority holds a very prominant postition and a crucial one too."
