And - when those rains come down in large quantities, filling creeks and streams, a number of folks itch to get out the canoe, john boat or inflatable and venture forth. OK, no problem. Statistics indicate that this season of the year especially draws boats and their occupants toward low head dams or drowning machines. A low head dam is a barrier across a body of moving water which is so uniform in height, that you can't see it from upstream, until you are about to go over it. The sound of these dams is also projected down stream so there is next to no warning of their presence to the unsuspecting.
High waters rushing over dams stirs the sense of adventure in too many booze lubricated boaters.
So, tragedy often results. Remember that last fall the waters were down and the dam didn't seem much of a big deal. Maybe you or your kids even walked along the crest of the then trickling dam. Plus the water is cold. You lose heat 25 times as fast to water as to air of the same temperature, and that is to non-moving water.
