I'm in the fourth year, but I haven't expanded past the cave river yet. I want to set up a decent military and build some noble rooms first. I know I haven't done much by the river, except lots of mining near there, some floodgates and a bridge made out of silver, but you'd think some nasty river creatures would come up through the wells. I've only had a single snakeman attack, and he got attacked by a war dog while my marksdwarf shot him down.
Edit: Well, there are corpses of poor forest creatures strewn across the wilderness from where my war dogs got a bit enthusiastic...but my dwarves are fine. I sent an unarmed peasant out to hunt and he wrestled a fox to death and brought it back. My hunters remain completely...alive.
