Any stream thermometer will work. We just take the surface temp, within a foot of the surface for consistency. If you have waders or a float tube a stream thermometer will do fine. If we're muskie fishing I'll attach one to a big topwater bait, cast it out and let it sit for 30 seconds or so and bring it back really quick to get a reading. I'll also clip it to my fly rod and stick it out as far as I can when I'm flyfishing.
There's some pool thermometers I've been looking into as well that may do the trick...they float and are pretty cheap. I've never tried one. Angler's Accessories makes the most affordable thermometer I've been able to find in shops around here. FishPond makes a really nice looking one, but are more expensive. It may be a good idea to calibrate your thermometer with your depth finder for consistency.
Also, William Joseph just came out with a laser or infrared thermometer that you just point at the water and it tells you the temp. Pretty neat stuff. We haven't tried it but it sounds cool. A bit more on the expensive end...
We've been trying to get a partnership with a shop or manufacturer to get a supply of thermometers to give out to people who are interested in keeping the lake info updated with us. We've had some progress in this area, but nothing going as of yet. If anyone has an interest in partnering with us to make this happen, please contact us.
