Mud seems to form everywhere in my fortress, and now it seems to be clogging up vertical water shafts. My traps and drains just don't work anymore because there's mud everywhere!
Is there a way to fix this?

Pave your waterways with constructed floors and no plants will grow.
If mud is appearing in the air, though, that's probably a bug.

[Sphalerite]

Constructed floors will still gather mud, but mud does not impede the flow of water.  Your traps and drains aren't being clogged by mud - something else is causing your system to fail.

Can plants impede the flow of water?
Impede even means completely blocking, in this case.

[Sphalerite]

Trees completely block the flow of water.  Saplings, shrubs, and grass don't.  You can stop trees from growing by building constructed floors, paved roads, or other buildings that don't block water on the tile.

Stockpiles will also prevent things from growing too, as I recall.

[Hyndis]

Empty vertical shafts can have mud, blood, or other contaminants floating in mid air for some reason, but this does not block anything.

Easy way to reproduce this:


Dig a deep shaft right down into the magma ocean from your fort. Order corpses and dye you don't want to use down the garbage chute. It will leave a trail of contaminants in open air on the way down into the magma.

Note that muddied underground floors (whether natural or constructed) will grow underground trees in older versions and in the latest if the flow is low enough.

[Sphalerite]

No, muddied constructed floors will never grow trees.  This has been true since 40d at least.  Natural rock floors will, if muddied.

[Hyndis]

Constructed floors can be muddy and you can even farm on muddy constructed floors, but plants will never grow on them.

Sorry to rain on your guys' respective paradas, but I am literally seeing tiles that I channeled before that now turn into solid floors again.

The description is
Muddy cave moss
A pile of mud

This used to be channeled. It no longer is, I assume the mud (or blood?) clogged it, or maybe it froze but I can't see any description of that. I can channel it again.

What's on the Z level under that? Is it mined out or a ramp, in which case this is very buggy behavior? If it's a full wall of natural stone, it sounds like the tile hadn't actually been channeled (or this is a very unusual bug indeed).

Mined out.
I also see up/down stairways that disappear. It happens when there's a lot of water in there, like they dissolve or something.

I lost a fortress to that once. Accidental flooded my stairway and grass would grow over the stairs destroying them. I didn't have the patience to re-dig everything from top to bottom as the stairs kept disappearing

That should have been fixed in 31.23 with "Stopped plant regrowth underground from deleting ramps and stairs..."

[Hyndis]

The vertical water shaft I'm using to irrigate my farms is completely normal. There is no mud or grass in open space.

There is, however a vertical line of blood and dye leading down into the magma from my garbage chute floating in open space for some reason, but nothing is blocking either vertical shaft.
