My son and I have been fishing Tawakoni for about a year. We have a Helix 10 MSI, and can not locate any brush piles. We look and look and then we just head over to 2 mile bridge eventually. I have looked on line for waypoints of structure for this lake but can not find any. There are several other lakes such as Fork and Palestine. Any suggestions other than look harder? We have spent countless hours trying to find them.
