Hello everyone. I have a chance to come fish pool 19 on the Mississippi River out of Fort Madison, Iowa. Im nervous about navigating the river and damaging my boat. Ive heard horror stories about wing dams and such. Does anyone know of a map card compatible with Lowrance that shows the Wing Dams? And is there anything anyone can tell me about navigating this pool. The do's and Dont's so to speak. Tournament is the TBF National Semi Finals October 9-10th.
