Good luck, let us know how you do. Can't say I have any specific bass hotspots for gan, only ever tried for pike there. There's plenty of docks up the Gan river that'll hold bass if you get there first. Other than that, there's shallow weedy bays surrounding all the islands close to gan and some rocky areas if you head east. I've been trolling the areas east of gan with worm hardesses looking for walleyes lately and have been getting some pretty sweet smallie action. It seems if you can find a rock pile on the river there will be fat smallies not too far behind. Try something that looks like a Goby.
