My underground pond wont fill up.

[Euruzilys]

Its about 7 blocks deep (from the top of the pond.) with 3depth and 6 wide space for water. When it rains, it fills up a bit. Then water just went away :(

The walls and floor are made from stone in U shape.

It has to reach some minimum amount before it stops evaporating/seeping. What I usually do to get a pond started is to manually control a dwarf and just keep dumping water into the pond. Once the bottom is covered with water it should start to fill on its own.

So like 1 block deep?

Probably don't even need to fill it up that far so that should definitely do it.

This has been happening forever. I have this game since it came out and the ponds just dont work sometimes. I have posted screen shots of full 6 deep ponds beofre just to watch it evaporate. If you find an underground pond and change one block in it (bottom or side) sometimes the pond will dry up also.

I've never had that problem with a constructed pond, as long as I fill it up a bit. And I have built an underground pond in every world I have played. My usual pond design is to use dirt or stone for the back blocks and stone for the front blocks of the pond. I also knock out any back blocks where there will be water. So far at least this design has been pretty stable.

Randomly, its fill up now, also fish spawned. I removed 1 of the top layer, making it 2 deep instead (but the bottom still the same depth from the 'sea' level)

I've never had a problem either with constructed ponds, but I've now built one, (post the recent patches), and even though I filled it 2 blocks deep, it keeps draining.

This is on the ice world -- I am filling by using snow blocks melting from bridges above. The pond is 9 wide, by 7 deep, with 2 shafts from the surface to allow snow to fall in as well. (And yes, it is below ground surface).

The pond is lined with Stone Wall bricks, both background and foreground.

Do you know -- does it have to be solid stone? I thought stone or brick walls also worked in times past...

I think it has to be below 'sea level'. Look at your extreme sides for that sea level.

I finally got it sorted -- looks like the bottom DEFINITELY has to be solid stone, (not stone wall). I also made the sides stone for good measure.

Added more ice blocks & soon fish began to spawn.

And, yes, it's below sea level.
