I apparently have great circulation because I did a water profile a couple weeks ago and the water temp is the same all the way to the bottom in all parts of the pond. No thermocline--no nuthin'. Wild, isn't it? As best I can tell the net temperature is about the same as in the big pond, which has higher surface temperatures, but a nice cool deeper area.
It's all a surprise to me. Somebody told me my name yesterday and I was surprised at that too.
