Here are some actual flood water pictures:
This, by itself, doesn't look like much of a flood picture, but I was on the bridge and the water just a few feet below the bottom of it. This was taken on Rte61/67 near 141 & 55.
This is old Gravois on the border between Sunset Hills and Fenton. The river is actually beyond the horizon of this image, about 1/4-1/3 mile up the road.
