Assuming that there's some logic behind underground river locations, it seems to me that the following might be good places to look: 'Upstream' from the source of a regular river (perhaps that river doesn't start there, but that's simply where it makes it to the surface first), in an area without many visible surface rivers (rain falls and has to go somewhere), and in areas with lots of limestone, which is where a lot of real-world underground rivers are.

It is in my understanding that underground rivers spawn cave fish. Also, above ground rivers channeled under ground do not spawn cave fish. Can someone verify this? --Flaa 12:55, 22 April 2008 (EDT)
- As far as I'm concerned creatures spawn only in respectable biomes. When you channel to cave river this biome does not extend up. It cannot be extended in any direction. If you could block flow of the cave river you could make small pond, from which cave fishes could travel up the channels to the aboveground river, but they will never spawn there.--Someone-else 14:38, 22 April 2008 (EDT)
In the current version (38c) underground river creatures do get caught in cages. I can verify this, I have a pit full of cave crocodiles, and I've caught numerous lizardmen. -- Lotus 9:58, (CST) June 11, 2008
Flooding
Do cave rivers still flood seasonally like in the 2D versions? Extar 15:11, 30 August 2008 (EDT)
Odd River
I have a very... odd river. It starts out as mist, in the middle of nowhere, and counts as a waterfall, then it goes on for a screen, then falls off a chasm. http://s4.tinypic.com/6sgi90.jpg The entire area 1z above is empty space the same size as the river. Then above that, rock. Where is the water comming from? It's mildly amusing, because random underground river creatures will spawn in it, swim around for a while, then fall into the chasm.
- A underground river tends to start within pure rock without any "real" reason. My actual map has one starting this way, too. It´s not as odd as yours. It goes south, then 1 z-level down, then nort-west, then down again, then east... There are five of these short parts before it goes down a chasm. I think this is normal when it doesn´t come from the edge or leaves the map.
