When commonsense fails desperate measures are called for. Let us stop power generation and storing of water at Mangla and Tarbela dams, allow Jhelum and Indus rivers to revert to the run-of-the-river mode, and merrily alternate between floods and droughts. One year of this will bring home to the followers of Benazir Bhutto and Wali Khan the many benefits of dams. Total disruption of agriculture, industry, town supplies etc for one year will be a small price to pay for cracking open their politicised minds. Maybe this is the only way we can get back to the 'Wapda Vision of 7 dams on the Indus, one mega dam every ten years. Still only 7 dams to Indias 4500, even a blind beggar has some residual sight left which we seem to have lost completely. ENGR KHURSHID ANWER, Lahore, December 11.
