You can get a cheap floating pool thermometer and attach it to a string so you can adjust the depth and check temps every foot or so from top to bottom. About a 60 second soak for each depth. That will allow you to find out what your deepest temps are with minimal cost. I use a railroad spike, loop knotted to the depth I want to check and let the thermometer float above it. Use black trotline string.
