Mist is created by water falling from one Z-level to another. Walking through it generates a happy thought for a dwarf.
Do not confuse with magma mist; this does not create a happy thought for the dwarf.
Generating Mist
AncientEnemy [1] devised a convenient way to generate mist.
This method relies on the fact that screwpumps pump water faster than water spreads out.
Simply put, water is dropped from the floor above and then immediately sucked up by the next pump.
When built underground, evaporation is nonexistent. (Above ground may still suffer heat evaporation, depending on temperature.)
The walls in the corner of the z=0 level are unnecessary if you instead create a Pond zone in one of the z=1 corner squares.
The statues in the z=0 level are to prevent cancel job spam. Otherwise, the one or two frames the water is there will make the dwarf cancel whatever job they had queued.
This system is generally only capable of maintaining a single 7/7 square of water, due to the way water descends z-levels.
Any additional water put into the system will quickly overflow into the pump chamber.
A movie [2] best illustrates the operation.
For fun, this same configuration can be used with magma [3] as long as magma safe screwpumps are used.
