So yeah, this is a really odd bug.  I've built a pump stack that draws water up from a flooded section of a fort, at the very bottom.  Water flows through it and get ejected our the side of the map (and it *does* drain out), however, the water level inside my fortress does not change.  I eventually had to abandon fort...

And DF then erased the save folder o_O

Anyways, I have an old version of the save, but I don't think it includes the pumping stack.  To be more precise, the water was several floors deep.  The first bug came when I expanded the hold tank, it almost instantaneously flooded to [7/7] water, and there was no drop in water level.

I haven't messed much with pumps yet. (I just dump the water into a bigger chamber below where it will eventually will evaporate)  But, is it possible that maybe the water is replenished faster than you are draining it.  Say you have a hole in your boat, and you are draining the water with a bucket? Just a guess.

Oops, did I say the save got erased?

I was looking in the wrong folder ._.  (I have two copies of the latest version; one for home, one for school on an external HD)

I'm not going to bother with downloading a 7MB save on my 56k, so I'll just ask what is probably a dumb question without looking at the fort: you aren't trying to pump out an aquifer, are you?

[Sukasa]

No aquifiers on this map.

how did the water get there in the first place, you said flooded, is it possible one of the squares is still connected to a source?

At the very least the square directly below the pumps should drop in level.

[Sukasa]

Drained out via floodgated channel from another tank, which is filled via (quadruple-floodgated) river connection.  Both sets of floodgates are locked shut.  As a note, if I turn off the pumps 'draining' the cistern, the water level does not rise, either.

Hi, I'm having the same exact problem. I know exactly where my leak came from (and I've plugged it up already, I miscalculated zlevels when making a fountain...). Unfortunately, while I'm bringing up an amazing amount of water, it keeps replenishing. I've taken a movie to show, if anyone would be interested, along with a save of my fortress.

I think the problem is that I have pressure coming from elsewhere that's never releaved. What I did, orginally, was

code:

~|..===.==
===..=...=
====...===
==========

with the expectation that the water would go up to the z-level it started, minus one (something I found when I experimented elsewhere). Unfortunately, my nice new room got flooded. Now, when I'm pumping, it seems to be pulling up water from the bottom level (unsurprisingly), but it is NOT depleting it from the other side.

Basically, I'm siphoning water from a never-dropping tank, even though there's a nice new floodgate blocking off any fresh supply.
