The thing that amazes me is that we don't have more drowning deaths each year than we do. The Handicapped Access is too far downstream to hear the siren, and you really do have to watch the water. If you hear a change in the sound of the water, even though you can't see anything, get out! It may be all the warning you get. Watch for increased amounts of foam on the water, weeds or other debris coming downstream, you'll notice that long before you realize the water is rising.
