When Sardar Sarovar's holding capacity goes up from 1.25 acre feet to 4.75 acre feet, it means it goes up by 3.8 times, not a mere 74 per cent, as reported by The Indian Express. Either the paper or the Narmada Control Authority which cleared the dam height to 138.62 metres got it wrong when briefing the media. News outlets should invest in simple calculators.
