Is that water currently flooding into that area?

Yeah, I found it in the first place because I heard water noises offscreen.

Water flows in the game may stop at a certain point, however. This was done to keep stability at the cost of a little realism.

I might be able to find a stable algorithm to have the water level itself out a bit more, but its very difficult to do in the 3D case without oscillations or the water going berserk.
