I didn't think they were, but I thought you might have got them from someone else who had a reason based on some standard for a club or organization. > I think 4" is > too shallow to give an accurate picture of what you'll > encounter out of the boat, but I may be all wet :). Four inches is around the depth that I notice a change from warm surface water to colder lake water in many still lakes. I can see it being useful in a turbulent stream where there is little temperature stratification, but in lakes it would be next to useless. I wonder if two foot depth would be better for reflecting the depth at which a paddler would be affected - five foot would be at their toes; two foot, at their waist. > I'm sure the USGS has some standard for their stream > guages, but I haven't checked yet. They must have. Does NOAA have offshore weather bouys with temperature readings? I was paddling yesterday within sight of the following bouy on southern Georgian Bay: http://weatheroffice.ec.gc.ca/scripts/marinegen.pl?Client=ECMar_e&city=45143 The water was warm to a considerable depth compared to what I expect in the more northerly areas of Georgian Bay. The recorder temp was 17C but it felt much warmer where we were closer to shore.
