I've been at this lake forever. It refuses to drain all the way because it's constantly raining. My dwarves finally starved to death because the farming patch was under water. Is there any way to fix this problem? Will adding extra channels help? Or am I jsut ognna have to find a new embark point?

[slothen]

if the lake is connected to the edge of the map it will fill with water infinitely.  Or are you talking about murky pools?

[HotSax]

I'm not really sure. It's just a body of water on my map, but it's not connected to the edge. I've been able to drain these things before, it's just that this one doesn't drain fast enough before the rain comes, and it's the only body of water on my map. So, is there any way to speed up the process?

[Passive Fist]

I don't know how to make it faster but if you turn off weather in d_init it'll stop raining.

And that would be cheating, too.

There are many other ways of farming than just draining a lake. Create a channel below the lake (or whatever water source you have) and divert the water to the area you want to farm. Before letting the water flow out, build a floodgate. Open it, let the water flow through your farming area, then close it. The water will evaporate.

There is the old burning lignite bin trick.  Hopefully that still works inthe latest version.  Of course, you need access to lignite and magma...

Oooooooh, you build the flood gate before you channel the water. Woops :p. Oh well, I'll do that with my next fort. Guess I'll just have to abandon this one.

I had the same problem in my last fortress, there was a lake I drained across my farm plots with the intention of building a wall to plug the hole once it was empty, the problem was it rained so much I could never build the wall.

I was able to fix the situation by building a giant 10x10 bridge over the lake this pervented the water from falling in the lake giving me time to drain the lake once more and the farm room which was now full to 7/7 as well. Once the water was drained out and the pond wall rebuilt I had my dwarves remove the bridge. Floors would work as well but take far longer to build and then demolish.

[Patchy]

Build a bridge or floor over it and the rain won't be able to refill it.

Floors would work as well but take far longer to build and then demolish.

Also might leave awkward submerged ex-floor materials, if you can't get in there and clear it out.  At least a bridge dismantles to an adjacent walkable edge on the same level.

(Unless you somehow manage to strand it and your building remover on a disconnected side-bit, of course...

When digging a long well-shaft down into the caverns, I usually try to insert a bridge at the top level of the cavern I'm digging into to catch the stone falling down the shaft channels.  The alternative is to not save the lowest channelling until you've cleared all the fallen stone off of that spot, and then breach the floor-thickness final stage without any rock falling into the water below.  If that's not possible, due to cavern height at that point, dig into the lowest non-cavern level early on (before being channelled into) deal with the waste rock on that spot how you wish, then channel it, add a bridge or hatch covering, then let the rest of the wellshaft be dug without fear of rock (or miners) falling into the pool, opening/removing the bridge or hatch when all is well.  IYSWIM.  NPI.


(Not that it causes any problems, saving the loss of the rocks involved which might be valuable ores/fluxes, etc.  But if you weren't too bothered about them, the alternate alternative is just to designate hidden and forbidden anything that does find its way into the water, of course.
