Punjab and Sindh have a difference of opinion on the canals taken out from the Indus River for Punjab. Sindh says it has first right on waters of the Indus. Punjab says under the Indus Water Treaty, a certain amount of water has to be transferred from western rivers to the canals previously serviced by the eastern rivers. Hence there is a need for consensus on the basis of give and take. On Kalabagh dam there can be no difference of opinion (even though, there is a lot, unfortunately). Sindh would get an increased share equal to that of Punjab despite the great disparity in area under cultivation and in population. Both would get their share from the surplus water stored in the reservoir, less in the dry years, more in wet, without in any way depleting the flow of Indus. The flow in the Indus would actually increase when Sindhs share of 37 percent of 6.1 mafequal to 2.2 maf is released into it. Since the flow would not decrease, there can be no adverse effect on the Indus delta, which has other problems. In view of the above there is no need for another effort at time-delaying consensus. We have already had one in the Water Apportionment Accord of 1991. Kalabagh dam is a win-win proposition, both for Punjab and Sindh. Sindh would get all the benefits of power and water it badly needs, without the displacement of even one person and submergence of even one acre of land. Let the country not suffer merely because we are unable to add 2 and 2 to make 4. -KHURSHID ANWER, Lahore, May 30.
