I get a few drops of water out of one side or the other fairly regularly in the 172. I check both and the float bowl every time I fly, before I move the airplane, and its not a big deal. Maybe we got more water in Tennessee but I've gotten water at some time or other out of every airplane I've flown includeing Air Force planes. I saw what looked like a quart come out of a Piper 140 that is used at a flight school and the instructor got in and flew. One of the partners in the 172 told me of a test Cessna did on a 172. They put one gallon of water in and were never able to get a gallon back out through the drains. Water hides in pockets till the right time to scare the crap out of you, Cessna built that in to keep you thinking about flat spots.
