I remember when I was a kid we were haying on a terribly hot day handling small square bales. Neighbors pond looked inviting so we jumped the fence and went swimming. It was a cow pond and stirred up to the point of chocolate milk color.
The top inch was so hot it felt like boiling water. Couldn't stand it. But the water below it was cool. As soon as it was mixed a little it was fine.
A pond can have two thermoclines if it is really muddy. One very shallow right near the surface that heats up quickly and also cools down the same I would presume at night. Out in that pond in deeper water there was a second thermocline of really cold water about 5' down.
