they will usually suspend just at the tops of the weeds. If the water is `12 feet and the weeds come to 7 feet, then set a cork at about 5 feet and try a slow retrieve. I've found that if you don't find them in one weed patch--move on. I have had very good luck with this method. The first time I found fish it was just with a flasher, but todays electronics should make it very easy. Good luck. We fished there toward the end of June but I'm sure the fish will stay in the weeds the rest of the summer also. Be prepared to catch some walleyes and northerns also.
