Is there even a full time bass guide on lewisville? I saw a guy at bass pro grapevine once and believe would guide there and grapevine. Can't remember the name but want to say it was a good Irish name. What little I know would be the tire reefs and boat slips (with brushpiles) close to creeks road bed, points or gullies that have deep water close by ( usually the old creek) Simple as narrow long rocky point that has deep water off it hopefully it being a creek and a channel bend. The dam where the old creek channel hits it. The causeway for I 35. The old dam. I would bet the bigger fish are deeper on the structure you caught the dinks. Just have to find the sweet spot.
