So I started a new fort halfway up a mountain, and I have a partly iced over stream.

^ Partly iced over brook. You've seen it all before.

Then I managed to find an underground pool. Cool! Except I managed to dig right through the bottom of it, and the whole freaking thing leaked through my fortress. Dang! But luckily I had designed the entrance of my fort with a water jet trap in mind, so it flowed out naturally. Water flows out the fort, down a cliff, spreads through the grasslands, and running off into the brook.

Where it contacted the ice is where it gets interesting.

^ That's when I first noticed it.

^ There it is 10-20 min later.

^ Another 10-20 min later. At this stage the underground pool has emptied 1 or 2 z-levels and the flow rate is dropping off.

^ 6th of Sandstone.

^3rd of Timber, (one game month later). That's the maximum extent it reached, the water started evaporating after that. I assume it'll melt during summer, but I haven't played that far and aren't going to - loaded a backup cause a Giant Olm rampaged through my fort.

I dunno, maybe this doesn't belong in bug reports, but it seems pretty odd to me to have puddles of water turning into walls of ice.

Known issue, especially since your water is passing into a biome that freezes at that time.

God, that must be some brilliant fucking idea for a trap.

Done it.  On some freezing maps with aquifers you can pump water out of the aquifer and have it immediately freeze.  Line your 2-wide entrance with pumps and trigger them when enemies are in the corridor to "clot" your hallway.

The problem is...

code:

  
  fort
WWWW  WWWW
W.PPIIPP.W
W.PPIIPP.W
W.PPIIPP.W
W.PPIIPP.W
WWWWxxWWWW
 outside
.=water channel
W=wall
P=pump
I=ice
x=tile from which pump can be diagonally attacked

easily solved by placing pumps up a z level, or by flooring a flood chamber in hatches to dump water down. I dunno if these ideas work though lol.... never even tried anything remotely like this.

Water would freeze instantly on any higher level, is the problem.  Unless I pumped magma into the level above THAT...  hm

Unless the water was indoors...right?

So you create a reservoir inside your base to hold the water, channel out to the pumps and cover it all with floor or walls to make it "indoor."  Above your main entrance you place your pumps to pump from the channel of indoor water and bombard the invaders with chunks of ice.

You may also be able to find a cliff map with the ability to drop freshly frozen ice from an internal reserve from above your main door and serve the same purpose.

Haven't tried it though.

I think it's just based on z-level and biome.
