Unless many smaller (and usually separate) groups had gathered at what they thought would be higher ground, or were caught unawares on their way there.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.
Perhaps accompanied by a gas release?
