i searched for this topic, but perhaps my search-foo is poor.  Maybe this belongs in bug reports...

I know the topics of rewall and filling channels has come up, but what about reflooring?

When rivers floot, there are sometimes squares created that transform from stone to "mud / dirt".  Most often you just get a muddy stone floor, which can be cleaned.  Sometimes though, you get a square that transforms to a "mud / dirt" spot.

I hear on the IRC chanel that this is due to a plant growing there and dieing, but i havent positively confirmed that (but neither do i have any reason to doubt it).

You cant build roads underground, and you cant smooth or clean the spot once it becomes dirt.  If you need a caravan path leading into your fortress, the only option seems to be to bridge over it, unless you have enough open space to engineer a cave-in on top of it, and then mine it back out.

So... is reflooring going to be addressed at the same time as rewalling and filling channels?

Thanks!

Or instead of making the need to re-floor...

Prevent the mud/dirt tiles from being created inside?

[Wahnsinniger]

Well, I know it doesn't help after the fact, but smoothed cavern floors prevent that permanent mud from forming, so if you can plan ahead of time, try to make sure all the important areas are smoothed before they get wet. They still get muddy, but they won't have spontaneous plants growing on them, so no 1x? hallways will suddenly get blocked by a tower-cap growing in the middle of them.

On a related note, I'd like to be able to damn active channels.  (For when you've linked directly to the cave river and regret it.)  Dwarves come along, drop stones in the anjacent channel, and when they're done get that tile as just a stone floor and an antiflood.

seconded.  I have a problem which i think is a bug, on the cave river.

I was digging out a nice large hall, and breached into a fork of the cave river, and now i have this lovely waterfall coming through my wall.

"thats nice," i thought "i'll just surround it with a little pool".  And so I proceded to make some floodgates to do this, and to filter the water through some statues to try to keep out nasty riverdwellers.

so i have something like this:

code:

 
#~~WWW###
#X~WWW###
#X.WWW._.
#&&WWW&_.
#......_.
#_______.
#........
#:wall
W:waterfall
~:river
X:floodgate
&:statue

so i pull the lever, and get this:

code:

 
#~~WWW###
#=~WWW###
#==WWW._.
#&&WWW&_.
#......_.
#_______.
#........
=:non-river flood-water

so i remove the statues and get this:

code:

 
#~~WWW###
#=~WWW###
#==WWW==.
#==WWW==.
#=======.
#=======.
#........

Thats nice, i think.  But I'd really like to adjust things there and have some statue islands.  So I pull the lever again to close the floodgates, and get this:

code:

 
#~~WWW###
#X~WWW###
#X=WWW==.
#==WWW==.
#=======.
#=======.
#........

"huh" thinks me.  "that sucked".  I think this is a bug with anti-flood not properly anti-flooding since there is a un-gated river square next to part of the flood, but its a floor not channel, so i think it should be okay.  If its a feature and not a bug, it sure would be nice to be able to dam up that floor square and mop things up a little.

[Mechanoid]

Any liquid that touches it's source will become part of that source.

If you build a channel that leads back to the river, that channel will become a new river. I think.

[Pacho]

Unless you have another floodgate on the other entrance.  I tend to connect my moat to the river on both ends with two floodgates.  No drainage problems so far.

That's how I lost my original farms.  I had to change my tower-cap farm into a normal farm, which I now realize I would have had to do anyway (my dwarves get thirsty).
