In the hottest days of summer here in east Texas, a distinct thermocline occurs in almost all bodies of water. At my place, where the max depth is 21 feet, the thermocline usually forms around 9 feet deep.

I haven't measured the water temps below the thermocline, though I do know the top layer gets to the upper 80s, maybe even 90 at times. But I'd be interested to know what other pondmeisters have found re temperatures below the thermocline. How big a difference? Does the bottom water, here about 12 to 21 feet, stay below 72F all summer? Below 75?

Yeah, I get it: "It depends." But at least I'd like to have some idea of what similar BOW do.
