Hi. As far as I know, Carp will go into deeper water in the winter as it is
warmer there.

Anyone know what depth the water will then stay the same temperature, no
matter how much deeper it goes? Is it just the top 10 ft for example, which
changes in temperature, due to surface losses?

At 4c or below water starts to get less dense which is why ice floats,
so when it is very cold there can be very cold at the surface and
warmer deeper down but when this happens the deeper water stays down
and gradually looses oxygen as the organisms use it up and the fish
will be up in the colder water. This only happens in deep lakes though
as in most lakes the wind keeps the water all mixed up. Unless your
lake has depths of about 20 meters or more this will not happen. look
for where the sun may warm the water or where a spring comes up in to
the lake, these are the warmer spots in most lakes. In most lakes in
the winter when it is sunny you may get some action about 2pm as this
is when the lake is at its warmest....
