Summary0004690: Water not stackable above 8 - 9 tiles
DescriptionWhen attempting to flood the world, my large (entire 3x3 embark map) water tank was unable to fill past 7/7 on the first layer, with scattered 1/7 water floating on top. It appears that the water evaporates faster than it accumulates when the water is on top of water, with a constant in source from above, or simply does not accumulate.
Steps To ReproduceDesign large tank with several z-level high walls. Connect several screw pumps to a nearby river and feed them into the tank. Activate screw pumps and wait for first level to fill up. Second level will not fill, despite the pumps dropping the water from above and the water unable to escape.

Description should Read "8-9 tiles". Use of tilde caused errors.

Do you have an ocean?

Oceans can cause funky issues with depth; I had one and was unable to make a 3 z-level desalination reservoir (with the top level above sea level).

No there is not an ocean, only a river.

1/7 water tiles can evaporate even when they're on top of existing 7/7 water tiles, and that's what's preventing your flood tank from filling up - if you want to fill up such a massive reservoir, you'll need an additional holding tank with a smaller surface area.

There's also the issue that, in version 0.31.xx, water can pressure-path off the edge of the map, so even if that tank is fully filled (e.g. using the DFHack tool 'dfliquids'), the only thing that will actually get flooded is a 10 tile diameter semicircle centered around each drain floodgate...

That is what I deduced. As far as the pressure pathing issue, can that allow it to travel through walls? I ensured that the walls were at least as high if not higher than the water level, but I stopped building after it wouldn't fill past the first z-level.
