It is quite correct that a consensus on Kalabagh dam was reached under the Water Apportionment Accord of 1991. What was not mentioned was that under the Accord Sindhs share in all future dams was increased from 34 percent to 37 percent by decreasing Punjabs share from 400 percent to 37 percent. Equal share for both despite the vast difference in population and the area under cultivation. Also that Punjab can utilise its 37 percent share only through the left bank canal at Kalabagh dam. Without this canal north Punjab will not get any water from any dam, present or future, on the Indus. The biggest cropland of the country will revert from irrigated to barani with a 500 percent loss in national food production. Mention was made of 10 maf release below Kotri, but the problem is that this amount of water is available only during the flood season the provinces are already sharing shortages during the remaining nine months. It is only by storing the required amount in dams that the requisite monthly dose can be made available for years round protection of the Indus delta. In any case 10 maf is almost 10 percent of the total water available to the provinces and can only be made available by reducing essential supplies to the irrigation canals. The latest foreign consultants study has determined 4.32 maf per annum, or 0.36 maf per month as sufficient for checking sea incursion. On the question of Nowshera drowning, Engr Shamsul Mulk is on record having said that during the flood season KBD reservoir level will be maintained at 860 feet above sea level i.e. 100 feet below Nowshera, and will in no way aggravate the flood situation at Nowshera. The flooding of Nowshera is because of the constriction to the river flow at the Kabul gorge and the Attock gorge which cause backflow in Kabul river. This flooding will continue even without KBL until Munda dam is built on Swat river. Under normal conditions the KBL reservoir at full capacity will remain 20 miles short of Nowshera in the Kabul river and 25 feet below Nowshera. It will be even lower from the other low lying areas and will not block normal drainage of the Peshawar valley or of the Mardan Scarp. Engr Khurshid Anwer, Lahore,?November 22.
