If I had to guess, it’s because the temperature above the water is constantly colder than the water itself – but that is what I actually don’t understand.
If the surface temperate is extremely colder than the temperature of the water itself, wouldn’t the cold “sink” that much faster, making the warm water “rise” at an equivalent rate, and thus forcing more of the cold water to the bottom?
Maybe a better post for stupid questions, but I’m very curious what causes this – perhaps this just applies to air, and not water? And if that’s the case, then also why?

Deep water is insulated by surface water, the surface water has to cool to freezing before the deep water can get that cold. For small stuff. And yes, that’s connected to what’s in contact with the colder air.
For REALLY deep, not middle of the small river deep, pressure actually prevents water from freezing. Remember that it has to expand to form ice.
