I'm working on transforming an underground pool into a towercap forest/dining hall/statue garden recreation area, and my first attempt at a waterfall has gone poorly.

Since I'm not really in the mood to work today I thought I'd solicit advice.

Here's the setup. Top pic is Z+2 where the water comes in. Bottom pic is ground level of the dining hall where I attempted to have the water drain.

As you can see from my mspaint skillz the primary problem is the water fricken splashed all over the place, muddying up my polished floors.

The original plan was to have the dwarves walk through the waterfall to get to the dining hall, and I may still do that, but I want ideas on how to avoid the splashing. Hopefully the grates aren't the issue because one of them is an artifact Hematite grate that I'd like to incorporate into the design.

I tried to look through DFMA for designs but I didn't find any that were quite like I wanted. Lots of waterfalls *near* dining halls/stairs, etc but I didn't find a waterfall that dropped right into the hall.

I'm not tied to that particular entrance, either. I may open up holes in the wall on all 4 sides eventually as the whole cavern is the 'room', I mainly wanted the walls for aesthetic effect and to help define the dining hall room size.

Thanks!

What's your drainage situation like? You'll want the waterfall to fall directly over the grates, and you'll want adequate drainage, like a chasm or closed loop waterfall.

What's probably happening is that either the waterfall is not falling directly on the drain, or water is not flowing out fast enough through the drain, causing it to get backed up and flood the dining area.

And mud can be removed. Just construct and remove floors over it.

What happened with my constructed waterfall (and may be the problem with yours) it that the drainage grate get filled with water and water piles on that water. It has nowhere to go but your clean floor. Try making a wider grate area. If that isn't the problem build a wall in front of the waterfall so it has to fall straight down.

*facepalm*

See the 7/7 water on the left a Z-level down? That's what the waterfall drains into. So I'm basically dropping water onto an already full pool.

The whole pool drains into a bottomless pit but I guess I'll have to dig a special drain down a couple more z-levels just for the waterfall.

Floor grates.

And make sure that Drain >> Source.

I dig a channel around the target tile (that the water lands on, for maximum mist), cover that with grates, and have several/many channels/tunnels leading down and out from that.
