I assumed that the 'river' under the castle was some kind of artificial waterway - part of the castle's own plumbing or ornamental facilities. After all, the castle's suspended in the air, so a natural river seems very unlikely, especially since we never see any evidence of water falling off the edge and back to the ground.
I was always more intrigued by the giant manta ray hovering near the door to Ultimecia's throne room. Statue? Lazy guardian? Superboss that never got around to it?
