Come-on Fritz...
Well, some people may not truly understand!

Once water freezes over on the surface, the ice and then snow acts as insulation, trapping the heat that's left in the lake. If you have a lot of Springs, or warm rainwater flowing in, it will continue to warm the bottom layers of the lake, even if the top is froze solid. Decaying matter, and other processes also add alittle heat and oxygen.
This is how all of the fish can survive!
It is almost like a reverse Winter thermocline, because all of the fish stay in just this warm zone....then because all of the fish are using up the oxygen on the bottom, this is the dead zone in the Spring...with the Spring turn-over, this is all the junk and smell that floats up! Then the lake processes start all over again!

I was privileged to be able to see this Natural Wonder in action!
