Okay catfisherman think you can figure this out?

i went fishing 2 days ago i was fishing creeks and rivers and stuff. well it rain alot in kansas for a good week and and it stop 2 days before i fished. the first creek i hit was a small one but i knew it was big enough to hold fish.it was 63 degrees.i was flatheading with a gold fish and channel catting with a worm. the water was about an inch higher then usual.( i really couldnt tell) anyways we stayed for about an hour and i caught an 8.5 pound carp. and i had a bite with a flathead that torn all the scales off the goldfish.(haha)so we relocate to the bigger creeks that go into Lake Pomona well all the pasters where flooded and the river was almost over bridge. and we got on the bidge and fished and didnt catch ****. it flooded it look like a gaint lake with tree everywhere with a few cows in the middle.(haha that was funny) i didnt know where to fish or what to do.so my question is when it floods and the creeks are claim would they come up shallow where the land is and feed or would they stay deep and not bite at all.(shore fishing)
