Digging underneath water

[Insertclevername]

So I am currently considering adding a moat to my fortress. I just realized, however, that my farm is one level underneath where the river would flow if I did so. Will that flood my base? I can extend the moat out but it'd be a huge hassle.

Only if you channel down will the water leak into your farm. As long as there's floor or wall separating it, it won't flood.

So, if it looks a little like this, it should be fine, and the water won't leak through, even though the ground would be sand?

It doesn’t consider all of the structural properties of the material you are digging through (yet), so it will be fine.

Yep. As above says; this will be fine.

Change "yet" to "anymore". I miss cave-ins.

If you go down exactly one level and your farm is there, unfortunately, the farm *is* the space that the water tiles actually occupy. When you're on the surface, you're also on the water surface. Down a level are the water tiles.

--- (surface)
|_| (moat)
__ (farm)

Is actually three levels. The moat is sandwiched between the surface and the farm. If you are on the surface and go down one level you should not be able to see a farm. You would have to go another level down to see it. The layer inbetween is the layer that will contain the water.

___ surface
___ farm

This is two levels

Consider that a floor tile that you place on the surface actually becomes the immediate ceiling for the farm below. If that helps you visualize the layers.

The old cave–ins didn’t consider the material properties of the layer you were digging in either.
