Need some help catching some crappie on one of these two lakes. I've got a guy at work who wants to learn how to fish. I've taken him out three times and we've caught two fish total. We went to loudon around turkey creek today with minnows and caught one small catfish. I'm trying to keep it simple since he's new at it. We tightlined around the bridge pilings, and I saw some fish on a drop off in about 40 FOW on the depth finder. We got a lot of bites there but one small cat was all we caught.
I know crappie should be up shallower, but I don't know where any brush piles are. I was thinking about getting some slip floats and trying them about 10-12 feet deep, but I don't even know where to begin. I have a fish finder so I can find something if I had a little hint where to look.
