I too fish these types of cover as mentioned above. With one exception I use a spinner bait with a small say # 4 size willow leaf blade. I toss out the spinner bait and let it sink on a tight line and then hop the spinner bait up off the bottom let it flutter back down and watch my line. If the line makes a tick or jumps, then a fish has got the bait and I set the hook. This trick works especially great around Beaver Dam's.
