40d Talk:Water

I dug into a Murky pool, all 7's, drained out 8 squares of 7's into my reservoir to irrigate my farm, then closed the floodgate up. The murky pool was mixed 6's and 7's. After winter, it froze over, and in Spring melted back into all 7's again. Apparently they can refill themselves. It did snow on top of the pool. Perhaps the snow melted and got it wet? --Tracker 20:36, 30 October 2007 (EDT)

As far as I know, if there's any water in the pool then they will freeze into ice walls. When the ice wall melts, it will always melt to depth 7, irrespective of how much water the ice was originally formed from. It is unaffected by snowfall, so if your murky pool ever completely dries out, it will never refill, even if you get lots of rain or snow. --Morlark

Do fish really flop around after you drain a pool? This didn't happen for me. --Turgid Bolk 17:08, 3 November 2007 (EDT)

Does anyone know what the water output of a brook is? As in, does it fill a 1-width channel any faster or slower than a river?--Xazak 18:29, 3 November 2007 (EDT)

Has anyone else seen stagnant water spontaneously appear beside a still? I had it happen twice, I swear that the still is leaking. --Krenn 02:58, 14 November 2007 (EST)

Likely, a dwarf for some reason dumped out a bucket or waterskin nearby. It tends to happen when you get job cancellations while filling a well or taking water to a prisoner or injured dwarf.--Knivesu 06:58, 3 December 2007 (EST)

Evaporation

I notice that evaporation isn't covered here or in Magma, and I think it might be a useful topic. My observation is that depth 1 fluids can evaporate if left alone. This means that you can get rid of arbitrary amounts of fluid simply by spreading it out enough, or by using a multiple-floodgate lock system to meter measured quantities of fluid out over a chamber floor. In my experience, evaporated water leaves behind mud, whereas evaporated magma leaves behind nothing. --Doctorlucky 16:45, 19 March 2008 (EDT)

Bend bugs

Should we add a section about the u-bend bug?

I've just managed to make a V-bend that can absorb infinite water as well as the U-bend that creates it. Basically I used ramps to create a dip in a pipe trying to make a u-bend, and when I poured a full murky pool into it I ended up with only the bottom three squares full of water. I then got a real u-bend going from another pond and as much as it poured into a pool the v-bend absorbed it all.

Can anyone reproduce? —Preceding unsigned comment added by Ikkonoishi (talk•contribs)

The u-bend is notorious, but never heard or ran into a "v-bend" before. A (side) diagram of your v-bend would be helpful in reproducing. As for pages, I'd say no, since they shouldn't end up being around a long time, but who knows. --Edward 18:13, 1 February 2008 (EST)

I was going to do one but couldn't figure out how to make the ramps. I'll just use \.

 Water went in. -->  ~.~########
                     ~.~.~###       <--- No water out

                     #####\~/###
                     ###########

Even when I brought infinite water from a normal u-bend two levels above it it would not flow through to fill the pond again until I capped the holes. Using periods to break up the ~ so I don't have to use nowiki tags. --Ikkonoishi 18:58, 1 February 2008 (EST)
