Next door neighbour stupidly dropped his car keys into his farm dam while
out on his kayak. Knowing I was a diver he asked if I could try and find
them. OK we are 670m but I have dived at higher altitudes and the dam was
only 7-8ms deep so no problems.

Interestingly the water temp at the surface was about 5C and than I hit a
distinct thermocline at 3ms and the temp was 8C. Surely even with not much
wind the colder heavier water should sink below the warmer water. The dam in
question is quite large probably 1/2 a hectare and has got good inflow from
a small stream. Wondered how the warm water could sit on the bottom even
knowing that Sydney's bad smog is caused by an inversion layer where cold
air traps the warm air and pollution in the basin.

Anybody else experienced this and any theories on why it can happen

PS I soon got out of the water without his keys, far to bloody cold and he
can afford some new ones. Only had a 5mm Farmer John with hood

You're in Australia, so the thermoclines are naturally upside down?

ps why in America are the toilet bowls so full of water. That shits me off
but not as much as the european ones with the plate thingy at the back so
you can give it a good look before you flush it.

Because we're not pigs?

He's got a reasonable point here, Popeye -- a lot of the
toilets in the US seem to use far too much water - yeah
it may mean that they look cleaner more quickly, BUT when
looked at from the point of view of someone living on one
of the dryest continents on Earth, it looks a lot like a
waste of water.

That speaks for itself.
