According to the rainfall charts (rather than the spreadsheets, Sandman must have been on vacation), water either came in excess in two separate occasions in a year or nothing at all during the long seasonal drought. Makes one wonder what kind of lifeform could have survived for so long in such a crappy environment (definitely not those pompous palm trees). No wonder people fought over the precious liquid resource (before the non-polar oil brush off the moody water), whether they wanted to be involved or not (sorry Jake); just hope that the weather was more stable back then.
