When you arrive at the city Cait Sith actually mentions something to do with how high the water was when he was last there. 'Flood' seems to be entirely the wrong word to describe the disaster. It sounds to me like it was actually a tsunami taller than the pyramid of Mhach... Not at all surprised something like that would wipe them out, technologically advanced or not.
