Frozen lake fortress
« on: February 21, 2009, 10:21:55 pm »
I've embarked on a cold biodome with a huge natural lake in it. My plan was to wait for the lake to freeze then dig down and build a tube from the floor to the surface so I could start an underwater fortress then eventually remove the bridge and enjoy only being accessible for a small part of the year.
After training my miners up before winter and then frantically making everyone carpenters we managed to build the tube just before the lake thawed (later when it did thaw we lost 4 dorfs who were stupid enough to ignore my restricted areas) but unfortunately water spawned in my tube rendering the whole idea useless.

Anyone got any ideas how I can stop the tiles being refilled with water? I could do pumps I suppose but I was kinda hoping to build a giant underwater dome, would be a bit rubbish if once a yeah everyone nearly drowned before I pumped the water out.

I do have an aquifer in the map as well but no magma as far as I know.

maybe dig out all of the natural tiles and replace them with walls/floors?

Water spawned in the tube? Was the tube built near the edge of the map, or the middle of the lake? Was there chunks of ice laying in the tube from when you dug it out? They can melt back into water.

Wait a minute... You built this tube from the top of the lake down to the bottom? Did you dig into the lake bottom, or floor over the lake bottom? I remember reading somewhere that the sea tiles each produce water, and if you have at the bottom of your tube a lake bottom tile...?

Dunno, but I'd like to look at your map.

....

if this is what happened, then it sucks. ive allways wanted to try doing this sometime.

also, ive often wondered about having some kind of dwarf diving suit. made of finely stitched leather and reinforced with chainmail.

also, having ice in contact with warm stone that has magma on the other side of it will aparently melt the ice. so you could use this on a glacier map to make an artificial hot spring type lake, which would be very easy to make into a pretty decent underwater dome fort.

You know you will have to build walls around your fortress, do not you? When lake defreezes, it would instantly flood everything you have builded.

Was a floor on the tube? Water pressure could've pushed water up into it.

Thats what its like only imagine several Z levels of the middle image

When it was frozen the entire middle section was all ice up/down stairs, so it could have been those melting.

Also I didn't pave over the river bed so it could be that spawning the water.
Its almost winter so I'll try paving and I won't leave ice stairs this time.

Huzzah!

I'm probably going to use your idea in a drawing, neue. Now I have an explanation for how to build an underwater tower. :P

Just letting you know.

Just wondering, do smoothed ice walls melt in spring?
