[40c] Channeled-out pond still generating 1-high water
« on: August 24, 2008, 07:30:41 am »



It continues to give 1 tile-high water every season (this is the bottom of the pond). I channeled out the little hill it was on top of, while the entire thing was frozen over, and now all the 'bottom' tiles that are exposed continue to make 1-high water every so often even though the pond doesn't actually exist anymore. This screenshot is maybe 3 years after I channeled it all out.

I think that several versions ago a feature was added that ponds refill by rain. Try to disable weather in the init.txt and if it still refills without rain - then it is a bug. If no - it is not a bug.

Actually, it was raining at the time..  But I don't think a pond should be filling up still if the pond doesn't exist, should it? The only thing left of the pond is the muddy ground, I channeled out everything 3 years ago.

If you [k] over the tiles, are they listed as "Murky Pool"s?  This is the special property that allows them to refill during rains.  I think you can build a dirt road over them and remove the murky pool status, which will prevent them from filling up with water.  If a dirt road doesn't work, you might try building, and then deconstructing, a paved road.

I may try this, but the point of the bug report wasn't to find a solution, it was to just mention it was a bug.

The interesting thing is that even the 1-tile water freezes during winter and leaves a solid wall of ice in its place, leaving some pretty awkward pillars of ice that caravans have to wind around.

Ah, I see.  I think the problem is that the pond feature is just very simplistic.  It has no idea that you removed the pond, since the actual tiles that define the pond, the murky pools, remained untouched (unless I misunderstood your description of what you did).  The only thing that changed were the tiles that were near the pond, but not part of the pond.  So it's less of a bug, and more of a simple-minded feature that isn't 100% intuitive.  Not sure that there would be any easy and appropriate way to fix this.

The most accurate way would be to remove murky pools altogether, and actually have some liquid physics operate when it rains (so that water collects, flows downhill, fills pool-shaped-areas, et cetera).  Unfortunately for some (since there have been people suggesting this feature), it doesn't look like it's high on Toady's priority list.  Besides, it'd just make weather calculations even more CPU intensive.

And likely just flood the lower mines and new players would have no freaking clue what's going on.

Well, from a realism point of view, lower mines should typically have pumps to get rid of excess water.

Could be an interesting feature to suggest: Flooded mines from rain and other sources that can be countered using pumps and cisterns.

That would be a cool feature to implement some time after or along the presentation/tutorial arc.

That could be turned on/off (off by default?) in the init of course.

I suspect this is already planned somewhere around all the bloats and devnotes...

I've set up a fort that channels rainwater from ponds into the cisterns. It's quite nice!
I think a lot of the water evaporates before it reaches the channels, but still, my reserve tank fills faster than the dwarves drink it.
