Since we are all noobs (including me, I have forgotten most everything from this game) I'd suggest that we use the LNP feature to DISABLE aquifers. Aquifers are generally a pain in the fucking ass to handle, I'd rather just undermine a pond and use that for water (or use a underground river, but that's beyond the point). Also, I can not play without a texture pack, DF ASCII is way too fucking messy.
