Fog forms when the air has a high relative humidity, the water vapour condenses to form very small droplets, which remain suspended in the thermal currents of the air.
This occurs when the air temperature, is above the freezing temperature of the water. Below this temperature, the water freezes and fall to the ground to form Frost.
At sub-zero temperatures, the air is very dry.

Why does fog form over lakes and ponds on cold days?
Fog might form over lakes and ponds on cold days because fog forms when the ground temperature is warmer than the air above it. This is also true over water when water is warmer than the air above it.
On a really cold day last winter roughly 30 C below the river in my town appeared to be steaming in the morning light. Could it have been fog over the water or another phenomena?
It's a form of fog sometimes called steam fog. Cold air over relatively warm water (any water in liquid form is warm relative to air at that temperature) will cause the air at the water-air interface to become saturated and cool to its dewpoint, condensing out moisture into fog.

It has to do with the temperature and dew point on that particular day.
Why does smoke fall when it is cold?
Rather than smoke, it is really a misty fog that comes about as the result of evaporation of the colder substance, whether in liquid form (cold water) or solid form (ice). Other substances can be used as well, for example carbon dioxide, nitrogen and more.
