The Headline reads "Bhumibol Dam able to retain over 7 billion cubic metres of water more" from Thailand's Nearly English Language Daily, "The Nation. Now do they mean more than the 6.191 billion cubic metres it already holds or is it 6.19 divided by 0.46 which gives us 13.45.
But the opening sentence states "The Bhumbibol Dam can retain over 7 billion cubic metres more of rain waters, the chief of the dam management said Monday". I realize that 13 is more than 7, but it seems to indicate that the total volume held can be a bit more, not nearly twice the estimated capacity. I doubt the Nation, one of Thailand's Nearly English Language Dailies, will clarify.
One thing I do know is we are in for rainfalls, or not.
