Looks like fun times with the kids! Good job!
I also noticed your temperature reading, and I also think that's probably pretty accurate. Water is most dense at 4 degrees Celsius (about 39 Fahrenheit; pretty close to the reading on your screen). If it gets colder (or warmer) than that it becomes less dense. So in the wintertime the coldest water (less than 4 C) will be right under the ice because it's less dense than the heavier 4 C water below it.
This is a handy feature of water because most substances keep getting more and more dense as they get colder. If water did that too, the entire lake would freeze, ice fishing would be impossible, and we would have nothing to do in the wintertime! []
