CLEAR LAKE IOWA help!

Hi.. My wife's family has a cottage home on Clear lake IA. For vacation she wants to go there around early Oct. I wanted to go to Lake of the Woods. But I have heard the fishing is pretty good on Clear Lake. So anyway I was wondering if I could get some info on what to expect for that time of year and where to fish for eyes etc. Also what/which is the best map to buy for Clear Lake? Also what other options do I have around that area?
Thanks
