Now I have this EPIC Waterfall, which is a Major river (fed from the West and a Small Stream above it feeding another Waterfall into it) which falls into another MAJOR River that curls around a hill a few Zs down. My plan is to build a Fortress which has a Military watch that extends out and around the Waterfall's well fall, and watches over the Major river below where I plan to build small ships and such (linked via bridges and attached to the worlds end) and have it so that it is a Major Port for a River Trade below. The thing is. I want my Main fortress itself BEHIND the waterfall, attached to the Outlook via some pipes in the wall. The thing is, I can't get the Dwarves to build the Walls and Floors needed to attach itself to the wall behind the water due to the waterfall putting water in the way....

I have tried building bridges into the area, but the Dwarves barely look long enough at the Bridges to acutally finish them, I have tried basic floor and walling, but the dwarves bounce away too quickly, heck I have even tried to do Pumps but I don't know if that took any effect to the water flow long enough to make a gap in the Fall to build in...

I just Savescummed to the start due to a few of my builders getting swept off the edge due to the fall picking them up and throwing them off the edge of the building supports...

What can I do???

Not exactly kosher, but I once had a similar fortress. Nice big mountain plateau with a river on top running down a side with a huge waterfall.

I decided to use dfliquids to make a temporary dam on top of the waterfall, dig into the cliff 'in' the waterfall, build a floodgate system on top of the waterfall to be able to turn it on/off at will, and then finally channel out the temporary dams and use dfde-ramp to clean up the channel mess.

OK, one, cool idea.

Two, divert the river. Dig a channel at least as big as the river that takes the water Somewhere Else. You'll probably need to use pumps, and bear in mind that you'll need to install the flood control equipment (floodgates etc.) on your diversion channel BEFORE you actually connect it to the main river, otherwise you just have the same problem again.

I am trying not to use hacks. So using dfliquids would be the last resort...


Diverting the River.... PFFT!!! LOL...
One sec I will DFMap it...

Just yesterday I've built a floor grate in existing waterfall's tube. It's very small - a 1 tile of water from nearest aquifier, but it got same problems.
I think best idea is to dig from the opposite side to leave only 1 tile wide gap and try to put grate there so that dwarf don't enjoy flight down caught by water. Then just stock grates near waterfall, burrow idle dwarfes nearby and start unsuspending the task to set 'em up. Eventually they'l sucseed, it cannot be permanently submerged.

That looks epic!  I don't think I've ever seen falls that huge before.

Any chance I could have the save?

My experience with waterfalls (mainly stemming from an aquifer that intersected a cavern) has been that grates are your friends.  They prevent flowing water from washing your dwarves over the edge, and can be placed fairly quickly even in the path of falling water.  They can't unfortunately provide connections for further construction, but you should be able to do something like

What about magma pump stack and magma drp? Hackless, the same effect.

[Hans Lemurson]

I think that constructing "Downward Stairs" allows for a walkable floor that lets fluids through it, so you could try those instead of or in conjunction with grates in order to get past the falls.

Its located near the top right, there is a haunted Marsh with an evil river attached to it. Its the Major river part that bends the the right there...

I might go with Grates, but the thing was I wanted to attach walls to the edge of the wall behind the waterfall but it should at least get the dwarves in, that is if they will WALK through the water itself. Might train swimming ^_^. Hopefully with some twitching work I can get walls on either side up so no one gets accidentally washed off like last time I tried...
Don't want to dig around due to the fact that I wanted it to be the only way in and out of the fort too...
Finally. Magma... You kidding me right. I ain't gonna drag magma all the way up there...

Edit :: Also the plan will end up like this...

Oh, I hadn't thought of constructing bounding walls AFTER the grates were in place.  Nice!  The tops of those walls will catch water though and so there could be some slight spillage onto the floors beyond, but it won't really be an issue unless you hate the color brown, since it should drain through the grates or evaporate fairly quickly.

Flooring over everything but the grate section, which will also have grates there...

[Hans Lemurson]

No, the walls were a good idea, don't abandon the bounding walls.  Floors will catch water just like the walls would, but with the added risk of idiotic dwarves walking onto them and getting washed off the platform.

Try this design (you can of course make it as wide as you want):

I suppose there's a chance your dorfs will construct some floor tiles, letting you build wall underneath. Floors are constructed fast enough. But you better be sure your dorfs won't get flushed away, maybe attach a floor tile to ramp or something as the water will spread around and flood surrounding tiles. Also it will drop down to nearest tiles so you will have to deal with more water when you try to expand your tube or floor fence above it.
But method is same - stock stone, burrow masons, and continue unsuspending construction. But this method seems to be too risky.
P.S. Althow if you're very dedicated you can build grated section beneath to cath flushed dorfs and start building walls and floors...
