Summary0000893: faillure to flood
DescriptionOn my map, I had linked a murky pool to some underground tunnels to lead it to a well, on the same level as the pool. when the tunnels and the pool had filled up to 7/7 due to rain, no flooding occured from the well, while this would happen in 40d.
Steps To Reproduce1: dig underground tunnels from murky pool, to site for well
2: build the well, on the same z-level as the pool.
3: wait several years for the pool to fill.

Conversely, I have a pond connected to a tunnel, which ends in a multi-level channel to a 3 level 6x6 pit. as it rains, my pond fills up --> flows in the tunnel --> fills the inner pool.

It takes a lot of rain, but my water level is rising. I've done this on 3 forts now.

ray10k, you'll probably have to upload a save for this one, or at least draw a diagram -- I can't tell whether "well on the same level as the pool" means the top of the pool or the bottom.

That's because your well is at the same height as the pond. Water doesn't flow back up to the SAME HEIGHT as the source, but ONE LEVEL BELOW.

Draco has it mostly right

Unpressurized water only flows up to one level below the source water.

Pressurized water flows up to the same level.

A murky pool is not pressurized. A river or screwpump is.

"Unpressurized water only flows up to one level below the source water." Does anyone have confirmation that this is intended behavior?

rivers are not pressurized either. I've already done u-bend testing on 0.31.01. I can't read Toady's mind, but I can say this behavior is consistent with 40d.
