I want to clarify this - there's a bias in my thinking where I think of the thermometer initially at air temp with air temp higher than water temp. This need not be the case and the comment on wind chill might make you think that the moving thermometer would record a colder temp. The thermometer has to reach equilibrium with the water. A moving thermometer will reach equilibrium faster than one that is static, since the moving water will either carry away heat (warmer thermometer) or add heat (colder thermometer) more quickly. If you take a temp reading quickly, a moving thermometer will be more accurate. If you leave it immersed long enough, it doesn't matter. Since you are dragging it for 10 minutes, you're likely getting a good reading. The problem of depth still remains.
