Has anyone had success with pumping water out of the aquifer? i am curious if it is possible, it could lead to the perhaps finding of bedrock underneath.  I kinda like starting with an aquifer, but the lack of stone really is bothersome, and if we could pump out the water and keep digging down, that could smooth things over.

next winter i will be ready to try my theory: ice i beleive if i can dig channels down to expose the aquifier during winter it should freeze like other water, i can then dig further down through it install some walls around my hole to stop it flooding come spring and hopefully get stuck into those rocks and ores

[Talith]

sounds intresting

Sounds like a good plan, will only work (potentially) on maps that are cold enough though.

my moat an river freeze each winter and just to be carefull ive dug it in the section of my map which is colder for longer during winter and spring, my biggest fear is my carpenters wont get the walls up in time and my miner will drown

I got an aquifer level and still managed to make a dwarf-home below it.

In my map I didn't have to do anything special. It was rather hilly so I tunnelled into the moutain until I found a non-porous rock. Gabbro I believe. Then tunnelled down.
It took me 3 tries but I eventually exposed enough of the area to find a watertight route down. But I don't dare dig much higher without some sort of method for dealing with floods.

I ordered some stone blocks from the dwarven caravan and build some screw pumps to try and pump out the water.  I'm using a combination of dwarven labor and windmills to pump out the water.  The problem is that the aquifer is more than one z-level deep and screw pumps can't be built on water tiles, as far as I can determine.  I'm going to continue working on it, but experiments are halted until I can buy some picks off of a carvan or I get some immigrant miners since both of them drowned and are at the bottom of a flooded pit.

The aquafer is underground, which never freezes. It might work if you dig out a large section and expose it so that it counts as above ground then wait for winter.

I ended up on a map with a very high aquifer (I'm lucky I have anything to dig into at all) because I wanted to play at the beach. If my map ends up freezing in the winter (I *think* I picked temperate but I'm not sure) I'll try it out.

Edit: Nope, the aquifer water does not freeze, even when the roof is dug out so it shows as above ground. in case anyone is wondering the ocean does not freeze either  :p

Burned, your problem is salt water. Salt water wont freeze!

Aquifer water will freeze if you expose it. Its relatively simple to dig through the aquifer when its frozen and wall it up permanently, as long as you have a cold winter.

I am developing a very complicated system of pumps and as soon as that blasted caravan brings some more blocks I'll get through the second z-level.  Don't know what I'll do after that though.  Those of you that have dug through frozen aquifers: how deep are they usually?

is that so? BAH!. oh well I already abandoned that fort due to a failed attempt at shaft fishing (fun fact: water flows diagonally. I know that NOW). Maybe I'll try a lake this time so I have fresh water.

thanks for the tip!

now if only freshwater lakes were easier to find....

Should be possible, needs constant pumping and amarok save your dwarven souls if the pumps do fail while they are behind the aquifier. My experiments did fail at the point that I didn't figure out how to pump water up. I'll try it again today.

This is pure awesomeness.

i used the freeze method i developed, but if you do go with (have to) use the pump method try walling it off once youve pumped out the water so you can stop pumping.
