Well, if the terrain was flat as alleged, there wouldn't be one particular spot 
to gather.
Also, if it was a flash flood, there would have been no time for them to 
gather, if it flooded slowly - well there would need to be an explanation as to 
how it could flood slowly given drainage rates and such, while still preventing 
the animals from reaching a safer spot.
